Signature Name 27 June 2016 Mitchel Hanlon Evans Head Airpark – Statement of Environmental Effects Page v Executive Summary The Proponent The proponent for the development is Evans Head Airpark Pty Ltd (http://www.evansheadairpark.com.au). Evans Head Airpark Pty Ltd is a company which has been established on behalf of the airpark proponents. Evans Head Airpark Pty Ltd are a group of passionate aviators and supporters of the aviation industry with a vision to preserve the heritage value and significance of the Evans Head Memorial Aerodrome. The Proposal Approval is sought for the development of an integrated residential, industrial and commercial aviation development as ancillary development to an existing air transport facility. The proposal incorporates the following key elements: Local commercial and recreational aerodrome; Small scale commercial uses and community facilities associated with the aerodrome; Museum for military aviation and community groups; Residential airside precinct with direct access to flying facilities; o 26 residential lots on the western side (museum precinct); o 59 residential lots on the eastern side (residential precinct); and o 23 commercial/industrial/private hangars. Aircraft maintenance and support hub; and Boutique hotel and convention centre. Approvals Required The project is deemed permissible due to the following: Development of the site as an airpark is permissible as an ancillary development to an air transport facility under the NSW State Environmental Planning Policy (Infrastructure) 2007. Evans Head Airpark – Statement of Environmental Effects Page vi Development of the site for subdivision is permissible as the project satisfies the heritage incentive clause 5.10(10) of the Richmond Valley Local Environmental Plan 2010. Approvals are required under the following: Environmental Planning and Assessment Act 1979; State Environmental Planning Policy 71 – Coastal Protection; State Environmental Planning Policy (Infrastructure) 2007; Integrated development s91 EPA Act 1979; o Heritage Act 1977; o Roads Act 1993; and o Rural Fires Act 1997. Clause 18 of State Environmental Planning Policy 71 – Coastal Protection requires a masterplan to be approved prior to consent if the development is located in a residential zone within a sensitive coastal location that proposes to subdivide land that will create more than 25 lots. Clause 18 permits exemptions from the NSW Planning Minster if there are adequate planning controls. An application for an exemption has been lodged with the Grafton office of NSW Planning. Impacts A number of specialist environmental studies have been prepared for the site from which an assessment has been made of the proposed development. These studies comprised: Servicing Strategy (prepared by Mitchel Hanlon Consulting); Acid Sulfate Soils Assessment (prepared by Mitchel Hanlon Consulting); Traffic Impact Assessment (prepared by Seca Solutions); Noise Impact Assessment (prepared by Vipac Scientists and Engineers); Flora and Fauna Assessment (prepared by Peter Parker Environment Consultants Pty Ltd); Contaminated Land Assessment (prepared by MTNKR Consulting); Evans Head Airpark – Statement of Environmental Effects Page vii Heritage Due Diligence Assessment (prepared by Weir Phillips Heritage); Bushfire Assessment (prepared by Mitchel Hanlon Consulting); and Socio-economic Assessment (prepared by Mitchel Hanlon Consulting). Service Infrastructure Based on a review of the servicing information provided by Richmond Valley Council, several options exist to extend water, sewerage, telecommunications, and electricity into the development site. Acid Sulfate Soils A preliminary desktop assessment was undertaken and indicated that ASS potentially occurs on the site. The geological and soil landform features suggest that ASS could exist and preliminary soil sampling confirmed that ASS may be present onsite. The extent of the ASS was not determined in the preliminary soil sampling. It is recommended that further soil analysis be undertaken to confirm the location of ASS hotspots. Broad management strategies and monitoring have been outlined, however more detailed management strategies and a site-specific monitoring plan will be prepared prior to construction works being undertaken. A detailed ASS Management Plan will also be prepared prior to construction to mitigate the potential impacts of ASS onsite. Traffic The proposed development site has frontage to both Woodburn-Evans Head Road and Currajong Street. It is proposed that an access point will be made available off each of these roads. Data on traffic flow was collected by Seca Solutions on Woodburn-Evans Head road. Peak flow was recorded as 266 vehicles per hour. It was calculated that daily flows would be approximately 2 700 vehicles per day. It is anticipated that the development will have a minimal impact on road safety. The current roads have good visibility and the traffic flows are expected to remain low. Evans Head Airpark – Statement of Environmental Effects Page viii Noise Noise modelling was carried out by Vipac Engineers and Scientists Ltd. The development of ANEF contours enabled the identification of potential impacts for comparison between current and future operations of the Aerodrome. At present the activities at the Aerodrome have been determined to be approximately 5,148 movements per annum (20152016). The projected movements for 2019-2020 are thought to be approximately 10,556 movements per annum. It was identified that recreational helicopter movements significantly affected the ANEF contours. As such, a second helipad was proposed and modelled with the original helipad for emergency uses only. The proposed development currently straddles the ANEF contours and the high density residential lots are in the >25 ANEF contour, which AS 2021 considers to be unacceptable for development, unless there is a ‘special case’. As the proposed development will be inhabited by aviation enthusiasts, who will use the Aerodrome for leisure, this development is considered as a ‘special case’. A comparison of the impacts on existing receptors surrounding the Aerodrome was undertaken; a comparison of the LAeq, day contours and the ANEF contours for the current and future scenarios with two helipads has determined: The number of existing residences that will sit between the 55-60 LAeq, day contour does not increase; and All existing residencies sit below the 20 ANEF contour for all scenarios. Overall, the impact on existing receptors will improve compared to the current situation with a second helipad despite the increase in flight movements. Ecology A Flora and Fauna Assessment of the site was undertaken in 2014 by Peter Parker Environment Consultants Pty Ltd (PPEC). Previous site assessments were undertaken by Peter Parker in 2001, 2004 and 2010 and by Geolink in 2010. PPEC identified seven (7) vegetation associations in the three (3) communities: woodland; shrubland; and grassland No threatened plant species or Endangered Ecological Community (EEC) was recorded at the site. Evans Head Airpark – Statement of Environmental Effects Page ix Desktop Search The NSW Office of Environment and Heritage’s (OEH) Wildlife Atlas maps a number of threatened plant species within five (5) kilometres of the site: heath wrinklewort; needle-leaf fern; red-flowered king of the fairies; and water nut grass. The threatened fauna species are well represented in the Evans Head locality due to the presence of habitats of high conservation value (i.e. Broadwater and Bundjalung National Parks. Reptiles and Amphibians Few reptiles were recorded at the site in the 2014 survey or on previous surveys. Four (4) frog species were recorded in the 2014 survey. These were the common froglet, the rocket frog, the northern banjo frog and the introduced cane toad. Birds PPEC reported the site supported large numbers of honeyeaters due to the prolific blossoming of heath-leaf banksia and broad-leaved paperbark. The peak of honeyeater activity was noted during the May 2014 survey due to the proliferation of flowering trees and shrubs. Characteristic “open country” species included the rainbow lorikeet, the scalybreasted lorikeet, the Australian magpie, and the torresian crow. Richard’s pipit was common on the grassland adjacent to the airport runways as was the masked lapwing. A number of raptors were recorded on most survey days. These included the Australian kestrel and the vulnerable square-tailed kite. Severable vulnerable bird species have previously been recorded adjacent to the site in 2001. One additional species, the square-tailed kite was recorded during the 2014 survey. Mammals With respect to mammals, two (2) large macropods, the eastern grey kangaroo and the swamp wallaby, were recorded grazing at the site in previous surveys (Parker 2001; 2004) and both were recorded in the 2014 survey. Traps yielded poor results in the 2014 survey. The bush rat was the only species of small mammal captured and was captured in Elliott traps along both transects. However, only nine (9) individuals were captured over the entire survey period. The cage traps failed to capture any fauna despite the presence of the long-nosed bandicoot being detected by the fauna camera and the northern brown bandicoot in hair-tune traps. The swamp wallaby, northern brown bandicoot and the grasslands melomys were recorded using hair-tube traps. Evans Head Airpark – Statement of Environmental Effects Page x Koalas Whilst koalas are known within the study area, no evidence was recorded during any of the fauna surveys. Potential koala habitat within the meaning of the SEPP does not occur at the site and therefore a koala plan of management is not required. Bats Ten (10) bat species were identified during the 2014 survey. Three (3) bat species recorded in 2014 are listed as vulnerable. Fish Fish species were recorded downstream from the study site on the southern side of Woodburn-Evans Head Road. Three (3) fish species were recorded in the 2010 survey and two (2) species in the 2014 survey. The introduced mosquito fish, which was recorded in the 2010 survey, is listed as a threatening process pursuant to the Threatened Species Conservation Act. The striped gudgeon and the firetail gudgeon are both relatively common native species in east coast Australian freshwater streams. Their presence suggests that the habitat quality is high. These species are found in habitats where the Oxleyan pygmy perch may occur. The Oxleyan pygmy perch was not recorded during the fish survey conducted for this proposal. The drainage regime from the site feeds into Oxleyan pygmy perch habitat. It is recommended that appropriate stormwater design be undertaken to mitigate any detrimental impact to this habitat. Recorded Threatened Species The PPEC survey (2014) recorded the following threatened species: Two (2) frogs: the wallum froglet (Crinia tinnula) and the wallum sedgefrog (Litoria olongburensis); Six (6) birds: the bush-hen (Amaurornis olivaceus) the glossy black cockatoo (Calyptorhynchus lathami), the osprey (Pandion haliaetus), the ground parrot (Pezoporus wallicus) the eastern grass owl (Tyto capensis) the square-tailed kite (Lophoictinia isura); and Seven (7) bats: the hoary bat (Chalinolobus nigrogriseus), the little bent-wing bat (Miniopteris australis), the large-footed myotis (Myotis adversus), the yellow-the bellied sheath-tail bat (Saccolaimus flaviventris), the eastern false pipistrelle (Falsistrellus tasmaniensis), the grey-headed flying fox (Pteropus poliocephalus) and the common blossom bat (Syconycteris australis). Evans Head Airpark – Statement of Environmental Effects Page xi The number of threatened species is not surprising given that the Broadwater National Park occurs within the study area. 7-Part Test S5A of the Environmental Planning and Assessment Act 1979 (the “7-part test”) must be taken into account in deciding whether there is likely to be a significant effect on threatened species, populations or ecological communities, or their habitats. In regards to each, the relevant section and comment is provided. a) In the case of a threatened species, whether the action proposed is likely to have an adverse effect on the life cycle of the species such that a viable local population of the species is likely to be placed at risk of extinction. No threatened plant species was recorded at the site. Accordingly, the proposal is unlikely to have an adverse effect on the life cycle of the species such that a viable local population of the species is likely to be placed at risk of extinction. The proposal is unlikely to have an adverse effect on the life cycle of any fauna species such that a viable local population of the species is likely to be placed at risk of extinction. b) In the case of an endangered population, whether the action proposed is likely to have an adverse effect on the life cycle of the species that constitutes the endangered population such that a viable local population of the species is likely to be placed at risk of extinction. No endangered populations listed under Part 2 of Schedule 1 of the Threatened Species Conservation Act 1995 (TSC Act) occur within the vicinity of the site. Thus, the action proposed is unlikely to have an adverse effect on the life cycle of the species that constitutes the endangered population such that a viable local population of the species is likely to be placed at risk of extinction. c) In the case of an endangered ecological community or critically endangered ecological community, whether the action proposed: No endangered ecological community was recorded at or in the vicinity of the site. Thus, the proposal is unlikely “to have an adverse effect on the extent of the ecological community such that its local occurrence is likely to be placed at risk of extinction.” Nor will the proposal “substantially and adversely modify the composition of the ecological community such that its local occurrence is likely to be placed at risk of extinction”. d) In relation to the habitat of a threatened species, population or ecological community: Evans Head Airpark – Statement of Environmental Effects Page xii Habitat modification or removal Threatened species and threatened species habitat has been recorded within the study site and study area. However, this habitat is conserved within the Broadwater and Bundjalung National Parks. Habitat isolation or fragmentation The area of habitat proposed to be removed lies adjacent to the Broadwater-Evans Head Road. Its removal is not likely to fragment or isolate other areas of habitat. In conclusion, the habitat of a threatened species, population or ecological community will not be modified, fragmented or isolated any extent as a result of this proposal. The importance of habitat to be removed The proposal will not require the removal of any habitat of particular significance to threatened species or the removal of an EEC. Thus, the proposal will not affect the long-term survival of the species, population or ecological community in the locality. The long-term survival of the species, population or ecological community in the locality Section 5A(d)(iii) requires an assessment with respect to the importance of the habitat to be removed, modified, fragmented or isolated to the long-term survival of the species, population or ecological community in the locality. This site is located in proximity to habitats which are recognised for their high conservation value (e.g., the Broadwater National Park). The proposal will not require any habitat to be removed, modified or fragmented to the extent that it will significantly affect the long-term survival of the species, population or ecological community in the locality. e) Whether the action proposed is likely to have an adverse effect on critical habitat (either directly or indirectly), The site does not contain any area which has been identified and declared as critical habitat under Part 3 of the TSC Act. Therefore, critical habitat will not be affected by the proposal. Evans Head Airpark – Statement of Environmental Effects Page xiii f) Whether the action proposed is consistent with the objectives or actions of a recovery plan or threat abatement plan, The National Recovery Plan for the Wallum sedgefrog and other Wallum-dependent frog species and the Oxleyan pygmy perch is relevant. The recommended water quality management controls will “restore essential habitat”. None of the other specific recovery objectives are relevant with respect to this proposed development. g) Whether the action proposed constitutes or is part of a key threatening process or is likely to result in the operation of, or increase the impact of, a key threatening process Potential threatening processes as defined under the TSC Act which may occur at the site include predation by foxes, introduced garden weeds, cane toad impacts, introduction of Phytophthora and the exotic rust fungi. However, the site will be landscaped using native species of local origin, and potential breeding sites for the cane toad will be minimised to the extent practicable and possible. This proposal includes the removal of woodland and shrubland. The extent of tree removal will destroy a sufficient proportion of one or more strata (layers) within a stand or stands of native vegetation so as to result in the loss, or long-term modification, of the structure, composition and ecological function of a stand or stands. The tree removal proposed is within the meaning of “clearing of native vegetation” as described above, this threatening process will increase as a result of this development proposal Under the Fisheries Management Act 1994, the proposal is unlikely to lead to any change or significant increase in any of the listed threatening processes, most of which are not relevant in the circumstances. Evans Head Airpark – Statement of Environmental Effects Page xiv Environment Protection and Biodiversity Conservation Act 1999 A search of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) protected matters database for the area was conducted on 1st December 2014. Parker has reported: One (1) threatened ecological community, fifty-five (55) threatened species and forty-five (45) migratory species were reported by PPEC. The threatened ecological community is lowland subtropical rainforest which does not occur at the site. The fifty-five (55) threatened species listed includes shorebirds, marine fish, turtles, whales and sharks thus leaving fourteen (14) terrestrial species and one (1) fish, the Oxleyan pygmy perch, as the only fauna species which potentially may occur at or in the vicinity of the site Using the Commonwealth Department of the Environment’s significant impact guidelines, assessment by PPEC indicate: No Matters of National Environmental Significance (MNES) were identified; Indirect impacts on the Oxleyan pygmy perch are considered to be negligible provided that the implementation of the recommended water quality controls is undertaken; No measures are proposed to for impact avoidance as no MNES were identified; and The impacts of the proposal are not considered to be significant within the meaning of the definitions provided in the significant impact guidelines. Recommendations To safeguard the potential Oxleyan pygmy perch habitat south of the site, PPEC recommends that road runoff is directed into pits with gross pollutant traps installed and a portion of the road runoff be treated by permeable pavers. Also, that roof water should enter the stormwater system via roof water drainage lines upstream of the gross pollutant traps where possible Runoff water should flow through vegetated open space (vegetated or bioretention swales) via surcharge pits for further treatment. Runoff water should then fed into the pygmy perch habitat rehabilitation area for final polishing. Evans Head Airpark – Statement of Environmental Effects Page xv Contamination Mr. Mark Imber of MTNKR Consulting was engaged to examine past site investigations and identify the most appropriate course of action regarding any historical site contamination. Extensive site investigations have identified past land uses have resulted in contamination. No further testing is deemed necessary as a Remedial Action Plan (RAP) has already been developed. As this RAP was produced prior to changes in the National Environment Protection Measures (NEPM), its relevance will be evaluated against the new NEPM requirements. The site will be remediated as required. Wetlands There is a wetland located to the north of the development site. This will remain outside the development footprint with no plans to alter or encroach on the wetland. Heritage Evans Head Memorial Aerodrome has significance arising out of use during WWII as an EATS training base and as a WWII memorial. The site is listed on the State Heritage Register (Item 01649), under the auspices of the NSW Heritage Act 1977, under the name ‘Evans Head Memorial Aerodrome.’ The site is also listed by Schedule 5 Part 1 of the Richmond Valley Local Environmental Plan 2012. The site is identified as ‘Evans Head Memorial Aerodrome (including runways, Bellman Hangar, timber huts and machine gun pit).’ A Plan of Management (PoM) prepared by GHD Pty Ltd (2009) exists for the site. The proposed development retains and upgrades the existing aerodrome facilities. The residential airpark and associated community facilities provide a viable source of funding to ensure its future viability. Provision of an aviation museum provides an opportunity to explore and interpret the heritage significance of the site. The proposed lots are located outside of the heritage zones identified by the Plan of Management for the site. A full understanding of the orientation of, and relationships between, the runways is maintained. This is key to understanding the site from the ground and the air. Groups of buildings on this site are not a new phenomenon; large groups of buildings existed on this site during World War II. The proposed location of buildings will not interfere with any significant spatial relationships or view corridors into, within or out of the site. Evans Head Airpark – Statement of Environmental Effects Page xvi Bushfire A bushfire assessment has been undertaken to determine the presence and degree of bushfire threat applicable to the proposed development. The site is identified as bushfire prone land as per the NSW Rural Fire Service mapping for the Richmond Valley LGA (July 2003). The vegetation type within the proposed development sites is characterised by ‘tall heath (scrub)’. There are large areas which are free of canopy or shrub vegetation and the groundcover is maintained. There are also a number of areas that are identified as non-vegetated areas and areas of reduced vegetation. The subject site has been identified as a potential bushfire risk (Category 1 – greater than 1 hectare of vegetation type 1 or 2). Bushfire mapping for the site indicates the western residential and museum precinct as Category 2 vegetation while the remainder of the vegetation is identified as Category 1. To increase access and defence mobility for fire trucks, it is recommended that fire trails be constructed along the northern boundary of the museum/residential precinct and along the northern boundary of the residential/hotel precinct. Recommendations include: Asset Protection Zones (APZs) be adopted for the proposed development to ensure protection from Bushfire; Building envelopes, be enforced through a section 88b instrument community title scheme; Minimum AS 3959-2009 building and construction requirements, be enforced through a section 88b instrument community title scheme; Asset Protection Zones should be regularly maintained to ensure the APZ is effective in providing an adequate protection area between assets and any potential bush fire events. APZ maintenance should include regular mowing of any grass. The requirements for Asset Protection Zone maintenance are set out in Planning for Bushfire Protection, 2006; Any future landscaping within the development should take into consideration the type of shade trees used to ensure the genus of tree planted does not contribute to any fuel load build-ups within the future landscaped areas of each allotment. Any future landscaping should comply with the principles within Appendix 5 of PBP (‘Bushfire Provisions – Landscaping and Property Maintenance’); Evans Head Airpark – Statement of Environmental Effects Page xvii Emergency fire trails be constructed to ensure emergency exits routes for residents, and ease of access for fire fighters in the event of a bushfire. Emergency fire trails will be required to be constructed to a standard which allows a fully loaded fire tuck to be able to navigate them. Construction Should be in accordance with ‘Access (3) – Fire Trails’ in the NSW Rural Fire Service Planning for Bushfire Protection; All internal roads associated with the development are constructed in accordance with Table 4.1 of Chapter 4 of the NSW Rural Fire Service Planning for Bushfire Protection (minimum width requirements); Socio-economic Over the period to 2036, the population of Richmond Valley is expected to increase by an average annual rate of 0.4% whereas the forecast for the Northern Rivers is 1.0% and New South Wales is 0.9%. Future forecasts for continuing population growth in the Richmond Valley require an estimated 9,900 new homes to be built by 2031, particularly for Casino, which will be the main growth centre. The Richmond Valley has historically been dependent on primary industries and food manufacturing enterprises supported by a number of agricultural businesses. There is also an active retail and tourism sector with growth in the creative industries, building and construction sectors. Evans Head remains a popular holiday destination with tourism and support services. It has a number of attractions, natural assets and State Heritage Listed sites as well as annual events. Tourism remains a focus of Richmond Valley Council and is viewed as a key mechanism to attract visitors and revenue to the region. Richmond Valley Council is actively looking for opportunities for developing a robust and resilient economy that can cater for future population growth. The Richmond Valley local government area (LGA) has been identified as a region with diminished social and economic performance. It has a low socioeconomic base and is among one of the most disadvantaged LGAs in NSW The local economy lacks diversify scoring low across a number of standards. The economy is significantly less diverse than all seven northern NSW councils and NSW more generally. May 2016 quarterly unemployment figures from the Department of Employment indicates the Richmond – Tweed region had an unemployed rate of 5.2% and a youth unemployed rate of 14.3%. The state average was 5.3% and 11.9% respectively. Evans Head Airpark – Statement of Environmental Effects Page xviii A competitive LGA is more likely to deliver sustainable economic growth resulting in vibrant social communities. However this depends upon current economic performance and what demographic advantages one LGA has compared to others. The conversion of the aerodrome to a medium-sized airpark will not only conserve the heritage and environmental values of the site, but bring economic opportunities for the local community whilst simultaneously reducing the cost burden on Council The proposed development will assist with diversification of the local and regional economy which is presently heavily dependent on the primary industries of agriculture, forestry and fishing and on manufacturing. There will be a lift in the aviation and hospitality related sectors. Tourism activity will also increase upon the completion of the museum complex. It is estimated that there is an initial employment opportunity of up to 30 jobs with an identified future potential of over 100 within the aviation-related industries. A further 23 jobs are predicted within the tourism and hospitality related businesses derived from the project. The civil construction phase, the subject of this development application will see an approximate spend of $20.9M. Further development will see a total estimated building spend of $136.5M. From a socio-economic perspective the project delivers against the triple line of sustainable economic development, environmental performance and social vitality. The proposal offers an opportunity to capitalise on inherent advantages and strengths of Evans Head locality to facilitate this. Regional areas that host an airport and aviation services generate an increase in economic development leading to expansion of businesses and community facilities Evans Head Airpark – Statement of Environmental Effects Page xix Justification for the Proposal Social and Economic From an economic perspective, the proposed development will benefit the Evans Head area through stimulation of the local economy and by providing job opportunity for local people. Richmond Valley Council is actively looking for opportunities to develop a resilient local economy that can cater for future population growth and provide employment opportunities for local people. The project is well aligned with the priorities outlined in Council’s strategic plans to facilitate a robust economy and provide for community priorities. Moreover, Council has identified Evans Head Memorial Aerodrome as a potential asset which could be utilised to deliver these goals. The proposal development will assist with diversification of the local and regional economy which is presently heavily dependent on the primary industries of agriculture, forestry and fishing as well as on manufacturing. The development will provide a lift in the aviation and hospitality related sectors. Tourism activity will also increase upon the completion of the museum complex. It is estimated that there is an initial employment opportunity of up to 30 jobs with an identified future potential of over 100 within the aviation-related industries. A further 23 jobs are predicted within the tourism and hospitality related businesses derived from the project. Local construction business will benefit during the construction phase and utilise local labour and materials. The local economy will benefit from increased consumer spending by local businesses supplying labour and/or goods and services during construction. Once completed, the airpark, hotel, aviation enterprises and museum will benefit the local economy by providing directed sustainable employment and local business spending on goods. The development will help alleviate the low diversity in the Richmond Valley LGA economy. From a socio-economic perspective the project delivers against the triple line of sustainable economic development, environmental performance and social vitality. The proposal offers an opportunity to capitalise on inherent advantages and strengths of Evans Head locality to facilitate this. Regional areas that host an airport and aviation services generate an increase in economic development leading to expansion of businesses and community facilities Evans Head Airpark – Statement of Environmental Effects Page xx Ecologically Sustainable Development Evans Head Airpark Pty Ltd is committed to the use of environmentally friendly practices in the development of the proposed facility. Furthermore, in considering this application, it needs to be remembered that Ecologically Sustainable Development (ESD) requires the effective integration of economic and environmental considerations in the decision-making process. Conclusion The proposed development will create a number of key benefits: Improve economic viability for the local economy through increases in employment opportunity, tourism opportunity and diversification of the local region; The NSW Heritage Council supports the development as the best outcome for the site. The development will implement a community title scheme and an ongoing sustainable funding mechanism for its continued maintenance and upkeep. The introduction and implementation of erosion and sediment control measures; Maintenance of the existing waterways and dams on the site for aquatic species; Sustainable wastewater irrigation; and Maintenance of native vegetation via landscape screening. This has great potential to maintain native flora and fauna in the area once established. This application is the result of a thorough assessment and evaluation of the environmental impacts which may result as a consequence of this proposal. Issues such as: noise, traffic, flora and fauna, site contamination and coastal sensitivity have been examined and reported in conformance with the requirements of this principle. Based on implementation of the proposed mitigation measures, the proposed development will not contribute to serious or irreversible damage to the local environment.

Approval is sought for the development of an integrated residential, industrial and commercial aviation development as ancillary development to an existing air transport facility. The proposal incorporates the following key elements: Local commercial and recreational aerodrome; Small scale commercial uses and community facilities associated with the aerodrome; Museum for military aviation and community groups; Residential airside precinct with direct access to flying facilities; o 26 residential lots on the western side (museum precinct); o 59 residential lots on the eastern side (residential precinct); and o 23 commercial/industrial/private hangars. Aircraft maintenance and support hub; and Boutique hotel and convention centre. This statement describes the existing land and the characteristics of the proposed development. The statement also identifies the potential impacts the development will have on the immediate environment. Where deleterious impacts are identified, measures which may mitigate their impact are presented. The regional context in which the development is situated is illustrated in Figure 1 (p11), while Figure 2 (p12) shows the site location within the locality of Evans Head. The proposed development site is illustrated on an aerial photograph in Figure 3 (p13). Site images are depicted in Plate 1 (p18) to Plate 5 (p20). Evans Head Airpark – Statement of Environmental Effects Page 9 The Proponent The proponent for the development is Evans Head Airpark Pty Ltd (http://www.evansheadairpark.com.au). Evans Head Airpark Pty Ltd is a company which has been established on behalf of the airpark proponents. Evans Head Airpark Pty Ltd are a group of passionate aviators and supporters of the aviation industry with a vision to preserve the heritage value and significance of the Evans Head Memorial Aerodrome. The members have been specifically drawn together for this project through their mutual love for aviation and desire to see the heritage-listed Evans Head Memorial Aerodrome not only preserved but significantly contributing to the economic viability of the region and local community, once again.

At present the aerodrome is supported by voluntary organisations and the local council, with very little income being derived for its own upkeep. With self-sufficiency a high priority for the developer of the land, the proposed Airpark provides the opportunity to not only conserve the aerodrome for continued use in general aviation, but also bring substantial economic and lifestyle benefits to the local and greater community. With the creation of a residential and commercial airpark, aviation related industries would be enticed to the area to start businesses and increase the number and range of employment opportunities. With an aviation centre such as this, more job opportunities are open to local youth, not only in aviation, apprenticeships, building, etc, but also in tourism related industries. With this in mind, Evans Head Airpark Pty Ltd is also determined to keep and pay homage to the significance of the aerodromes military history, both out of respect to the part the aerodrome played in World War II, but also out of respect to the relatives and friends of our men and women who worked and played there in times of war. This goal will be achieved with the creation of a military museum similar to the Temora and Point Cook aviation museums. It would initially be built around the last surviving Bellman Hangar, eventually leading to the creation of a very large scale museum with a strong RAAF theme in line with its heritage. The local community would be consulted and invited to take an active role in the nature and operation of such a museum. The last surviving Bellman Hangar has been restored by the proponent ahead of time in good faith jointly funded by the proponent ($250K), the Richmond Valley Council ($250K) and the Australian Federal Government ($130K). The facility is occupied by the recently established community based not for profit organisation, Evans Head Memorial Aerodrome Heritage Aviation Association (EHMAHAA). EHMAHAA was successful in being allocated one of six ex-RAAF F-111s loaned to non-defence museums. The restoration of the last surviving Bellman hangar was brought forward and completed in record time to allow the Evans Head to satisfy the timing requirements of defence. Evans Head Airpark – Statement of Environmental Effects Page 21 The larger future museum facility will be sited in the Museum precinct on the Western side of the aerodrome to house the expanding collection of EHMAHAA and available to other local community groups such as the Evans Head Living Museum. The new facility will serve as a centre for multiple community based groups ensuring a close relationship with the aerodrome. Local community would be consulted and invited to take an active role in the nature and operation of such a museum. The proposal incorporates the following key elements: Local commercial and recreational aerodrome; Small scale commercial uses and community facilities associated with the aerodrome; Museum for military aviation and community groups; Residential airside precinct with direct access to flying facilities; o 85 residential lots; and o 23 commercial/industrial/private hangars. Aircraft maintenance and support hub; and Boutique hotel and convention centre. Evans Head Airpark Pty Ltd believe a residential and commercial airpark facility, with its aviation focus and historical significance, is unique and will attract a more varied clientele that can only be of added value to the residents of the Richmond Valley. This airpark will bring added prosperity and significance to the Evans Head area and distinguish it from the usual development often found in coastal towns. Staged Development The development will be staged in accordance with the definition of s83B of the Environmental Planning and Assessment Act 1979. Development consent will be required for the construction of the museum, hotel, hangar homes and industrial hangars. A construction certificate will be sought to allow for the construction of the access roads, internal roads, utility services, water supply, sewerage and stormwater. Some taxi-way works will also be necessary. Evans Head Airpark – Statement of Environmental Effects Page 22 Staging The residential, museum and industrial lands will be developed in stages. The eastern precinct will comprise the eastern residential and industrial areas. Initial access will be via Memorial Airport Drive with final main access being via Currajong Street. Memorial Airport Drive will provide access to the industrial area and the medium/high density residential area. The Memorial Airport Drive will facilitate access for construction traffic and the first three residential stages. The third, fourth and hotel stages will gain access via a new intersection from Currajong Street. The western precinct is comprised of the proposed future combined aviation museum and community centre and residential airpark area. Access to the western museum will occur via Woodburn-Evans Head Road. This precinct will be developed after the eastern precinct. The aviation museum will relocate from the existing Bellman Hangar to the museum precinct. Development consent will be required for the museum complex. A final staging plan will be submitted for approval prior to any application for any construction certificate. Museum Whilst it is intended the Evans Head Memorial Aerodrome Heritage Aviation Association be the principle user of the Museum, the complex will be available for other museum groups within the Evans Head area to take up residence within the museum building. Other community groups will also be invited to utilise shared areas with other community groups within the building. The men’s shed group will also be able to move to the museum site. It is not the intention for the site to be the sole bastion of any one group. An architect’s impression of the museum complex is shown in Figure 8 and Figure 9 Evans Head Airpark – Statement of Environmental Effects Page 23 Figure 8: Museum Concept – Aerial Perspective Figure 9: Museum Concept – Ground Perspective Evans Head Airpark – Statement of Environmental Effects Page 24 Community Title Scheme The development will be subdivided and managed as a Community Development Scheme. The airfield and its curtilages will be held within a common lot parcel (Lot 1) whilst the hangar homes, industrial sites, hotel, museum and wetlands will each have their own parcel and separate title. As the project will be staged, development precincts will be created and registered with NSW Land and Property Information. The scheme will have an overarching management plan. Each hangar-home lot will have an individual Torrens Title. These will be available for sale. Restrictive building covenants will be created under Section 88B of the Conveyancing Act 1919. The covenants will control the characteristics of the buildings to ensure the design and construction standards are appropriate for the development. A sinking fund will be established to pay for ongoing management and maintenance. The fund will be funded via levies imposed on each of the lots within the scheme. The levy will be proportionate to each lot’s unit entitlement. Evans Head Airpark – Statement of Environmental Effects Page 25 Previous Development Consents 2.6.1 DA 2011/223 Retirement Village, Subdivision and Childcare Centre Development consent was issued for DA2011/223 for the development of an Integrated Retirement Village including Community Complex, a childcare centre and the subdivision of Lot 1 in DP 1193927 to create 24 residential lots. The consent was issued by the Joint Regional Planning Panel (JRPP) on the 15th March 2012 (JRPP, 2012). A Section 96 amendment to the consent was approved by Richmond Valley Council at an ordinary meeting on 19th February 2013 (RVC, 2013). It is understood contracts have been exchanged with RSL LifeCare Limited for the residue lot (RVC, 2012). The land is held as Lot 1 in DP 1193927 with current title held by Richmond Valley Council. 2.6.2 DA 2011-097 Remediation Works Grant funding by the Federal government of $1,625,200.00 together with additional funds of $1,923,600.00 was used for the remediation of part of the Evans Head Memorial Aerodrome site (RVC, 2013). Development consent was issued for DA 2010-097 for remediation works at Evans Head Memorial Aerodrome by the JRPP on 18th January 2011. The development was for the proposed remediation of identified contamination across parts of the Evans Head Memorial Aerodrome and former Council Depot. The contaminated materials were to be excavated to a nominated depth and transported to Vacant Industrial Land (VIL) northwest of the remediation area. Soils were to be stockpiled according to level or nature of contaminates. Once materials have been determined suitable for industrial land use, the materials will be spread across the VIL for future site development (JRPP, 2011). Evans Head Airpark – Statement of Environmental Effects Page 26 Existing Environment Site Location The land is located on Lot 3 in DP 1217074. This lot comprises the entire aerodrome site. Lot 1 in DP 1193927 located to the immediate southeast and bounded by the Woodburn-Evans Head Road, Curragong Street and Memorial Airport Drive, was originally part of the site until it was excised from the parent parcel. Council intends to sell a strip of land with frontage to Curragong Street as individual residential allotments. Council intends to dispose of the remaining residue when opportune. The proposed development site is located along the Woodburn-Evans Head Road approximately 1.5 km north-west of the centre of Evans Head. Specific details of the subject land are included in Table 1 (p27). Table 1: Site Identification ASPECT DESCRIPTION Site Owner Richmond Valley Council Site Address Memorial Airport Drive, Evans Head Lot / Section / DP 3 / 1217074 Town / City Evans Head Parish Riley County Richmond LGA Richmond Valley Approximate Site Area 185 Ha Current Zoning * RU1 Primary Production and E3 Environmental Management Current Use Evans Head Memorial Aerodrome Site Information Sourced from ACS Title Search * Zoning under Richmond Valley LEP (2012) The existing memorial aerodrome site is characterised by World War II aviation infrastructure, including four runways, associated taxi-way and aprons as well as a number of hangars, including a recently restored Bellman Hangar. Vegetation is extensively present within the site, with large patches of native heath vegetation located within the northern half of the site, with patches extending across the southern half of the site in areas not occupied by aviation infrastructure. Evans Head Airpark – Statement of Environmental Effects Page 27 The site is bound by the Woodburn-Evans Head Road and Currajong Street on the south-western and south-eastern sides respectively. Land to the north, north-west and east of the site has been identified as the northern extents of the Broadwater National Park. Existing Activities & Land Use 3.2.1 Surrounding Area Broadwater National Park is the dominate landuse to the west, north and east of the aerodrome. Richmond Valley Council’s landfill and wastewater treatment plant are located to the immediate northeast of the site (1/605097 and 10/1075394). Crown Land is located on the eastern boundary (2/1012063, 7094/1113512 and 7019/1051692) followed by Broadwater-Evans Head Road. Land use is residential from the southern end of the national park on Broadwater-Evans Head Road (near Camp Koinonia). This residential landuse continues south along Broadwater-Evans Head Road and west along the southern side of Currajong Street to Woodburn-Evans Head Road. Airforce Beach lies approximately 550 metres from the aerodrome’s eastern boundary. An industrial estate is located to the southeast of the aerodrome. The sole public access to the aerodrome is via Memorial Airport Drive. Access within the industrial estate being from to the industrial is via Memorial Airport Drive. A vacant land parcel is located to the immediate south of Memorial Airport Drive. The parcel was the former works depot for Richmond Valley Council. Remediation works have occurred on the site. Development consent has been issued for the development of a retirement village. A strip of land along the Currajong Street frontage has being developed for residential use. Both the vacant land parcel and the industrial estate were excised from the original the aerodrome land parcel. The aerodrome’s southern boundary is bounded by Woodburn-Evans Head Road. The land located on the southern side of Woodburn-Evans Head Road forms part of the Broadwater National Park or is held by the NSW Aboriginal Land Council. Peri-urban land holdings are located on the southwest perimeter of the aerodrome. Evans Head Airpark – Statement of Environmental Effects Page 28 Physical Environment 3.3.1 Topography The subject site is identified as falling within the Coastal lowlands (on weak sedimentary rocks with littoral alluvial plains) of the Clarence Lowlands region. The area consists of moderately weathered bedrock (>50%) (2050%). The topography range is approximately 330-335m ASL AHD (CSIRO 2006). 3.3.2 Soils and Geology 3.3.2.1 Soils The topsoil within the local area is generally described as brownish grey coarse loamy sand. The sub soil contrastingly is described as being comprised of a white / light grey coarse sand. The site is deemed to be impacted by acid-sulfate soil as both the subsoil and topsoil are identified as being naturally moderately-highly acidic with a pH of approximately 4.2 and 4.4 respectively (CSIRO, 2006). The soil within the area is generally described as being a Rudosol (NSW OEH, 2014c). 3.3.2.2 Geology The subject site is identified as falling within the Cunningham Slopes, of the New England Moreton Uplands Province (CSIRO, 2006). Specifically the subject site is generally identified as being situated on marine, barrier and estuarine sediments, some with veneer of undifferentiated alluvial deposits (sand, silt, clay and gravel). These formations include estruarine basin and channel, intertidal, back-barrier, washover and tidal delta deposits and organic swamp deposits (Dept. of Mines, 1971). 3.3.3 Climate The nearest Bureau of Meteorology (BoM) automatic weather station (AWS) to the subject site that contains historic temperature averages is located at Evans Head RAAF Bombing Range (station number 058212). Validated data is currently available from this station since records began in 1998-2014 (Bureau of Meteorology, 2014). This site is located approximately 8 kilometres from the proposed subject site. Evans Head Airpark – Statement of Environmental Effects Page 29 3.3.3.1 Temperature A graph displaying the monthly fluctuations in mean daily minimum and mean daily maximum temperatures at the Evans Head RAAF Bombing Range AWS is shown in Figure 10. The average annual maximum daily air temperature ranges between 20.4 ºC and 31.0ºC, and the average annual minimum daily air temperature ranges between 18.7ºC and 26.1ºC (Bureau of Meteorology, 2014).

The rainfall experienced at Evans Head RAAF Bombing Range AWS can be described as high, as the mean annual rainfall for this AWS is 1467.4 mm/year, the median rainfall is 1464.4 mm/year and the rainfall is predominantly summer rainfall (Bureau of Meteorology, 2014). Figure 11: Mean Monthly Rainfall Evans Head Airpark – Statement of Environmental Effects Page 30 3.3.4 Service Infrastructure 3.3.4.1 Water Supply Based upon a review of the servicing information provided to MHC by RVC, water reticulation to the nearby existing industrial and residential developments is provided via one of the following water mains are located at or near the site: Memorial Airport Drive – A 150 mm diameter water main is located in the northern portion of the road reserve of Memorial Airport Drive. This water extends into the development site and terminates at the existing water metre adjacent to the tarmac / hanger area. The industrial area adjoining Memorial Airport Drive and the residential area to the south are both serviced via an existing 100 mm main. Woodburn-Evans Head Road – A 200 mm diameter water main is located in the northern portion of the road reserve of WoodburnEvans Head Road along the frontage of the proposed ‘museum’ site. It is noted that this main is owned by ‘Rous Water’; and Broadwater-Evans Head Road / Flame Street – A 150 mm diameter water main is located in the eastern portion of the road reserve of Broadwater-Evans Head Road. The residential area to the east of Broadwater-Evans Head Road / Flame Street is serviced via an existing 100 mm main. 3.3.4.2 Sewerage Based upon a review of the servicing information provided to MHC by RVC sewage from the existing industrial and residential developments located within the vicinity of the development site is conveyed to the Evans Head Wastewater Treatment Facility (WWTF) via one of the following rising sewer mains are located at or near the site: A 300 mm diameter rising sewer (pressure) main traverses middle of the site. The main runs from Woodburn-Evans Head Road to the Evans Head Wastewater Treatment Facility (WWTF) adjoining the site to the north; The industrial estate immediately to the south of the site is serviced via a 150mm gravity main which discharges at a sewerage pump station located along Currajong Street. Sewerage is then conveyed via a 300 mm diameter rising sewer main which connects to the rising main traversing the site and then discharges at the WWTF located to the north; and Evans Head Airpark – Statement of Environmental Effects Page 31 Sewerage generated within the nearby residential land to the south and east of the site is conveyed to a pump station located adjacent to Pine Lane. Sewerage is then pumped via a 200 mm diameter rising main situated in the western portion of the Broadwater-Evans Head Road / Flame Street the road reserve to the WWTF located to the north. 3.3.4.3 Stormwater Drainage Based upon a review of the servicing information provided to MHC by RVC, management of the stormwater generated within vicinity of the nearby existing industrial and residential developments is provided via one of the following water mains are located at or near the site: Stormwater generated within the region west of the tarmac area and the residential area to the south is conveyed via a combination of overland and channel flows and is discharged at the existing headwall and associated culvert located within Woodburn-Evans Head Road. Stormwater is then directed via an existing open channel through Lot 543 in DP 48550 and discharging into the Evans River via an un-named drainage line; The north western portion of the site is deemed to drain via overland flow towards the wetland area adjoining the Broadwater National Park.; and Stormwater generated within the eastern of the site is conveyed via a combination of overland and channel flows and is discharged at the existing headwall and associated culvert located within Broadwater-Evans Head Road. Stormwater is then directed via an un-named drainage line (located within Lot 469 in DP 755624) and is then discharged in to the Pacific Ocean at Airforce Beach. Stormwater generated within the existing tarmac areas, adjoining industrial estate and parts of the residential area to the south east and east is conveyed via channel flows and is discharged at the existing headwall and associated culvert located at the intersection of Currajong Street and Broadwater-Evans Head Road / Flame Street. Stormwater is then directed via an un-named drainage line (located within Lot 7040 in DP 1052589) and is then discharged in to the Pacific Ocean at Airforce Beach. Evans Head Airpark – Statement of Environmental Effects Page 32 3.3.4.4 Telecommunications A review of the available ‘Dial-Before-You-Dig’ plans indicates that, at present, there is extensive telecommunication infrastructure exists within the local area. All telecommunication services will be provided via the extension of the existing telecommunication infrastructure located within the vicinity of the site. A suitably qualified consultant will be engaged to undertake the necessary telecommunication design upon the issue of Development Consent. Subsequent confirmation that a suitable telecommunications supply is available for each lot will be obtained from Telstra/NBN following the construction of the infrastructure and forwarded to Council. 3.3.4.5 Electricity A review of the available ‘Dial-Before-You-Dig’ plans indicates that, at present, there is extensive electricity infrastructure exists within the local area. It is our understanding that at present electricity power supply is supplied to the site and nearby industrial lands via overhead reticulation. However, future electrical servicing will be provided via underground reticulation. A suitably qualified consultant will be engaged to undertake the necessary electrical design upon the issue of Development Consent. Subsequent confirmation that suitable electrical services are available for the development will be obtained from Essential Energy following the construction of the infrastructure and forwarded to Council. 3.3.4.6 Natural Gas A review of the available ‘Dial-Before-You-Dig’ plans indicates that, at present, there is no existing natural gas connections located within the development site. As such, no allowance has been made to supply the development with reticulated gas. 3.3.5 Road Network and Traffic The proposed development site has frontage to both Woodburn-Evans Head Road and Currajong Street. It is proposed that an access point will be made available off each of these roads. 3.3.5.1 Woodburn-Evans Head Road Woodburn-Evans Head Road runs along the southern boundary of the site. It is single lane in both directions and operates under a posted speed limit of 50km/h increasing to 80km/h outside the urban area. Evans Head Airpark – Statement of Environmental Effects Page 33 3.3.5.2 Currajong Street Currajong Street also runs along the southern boundary of the site and connects with Woodburn-Evans Head Road at a roundabout. It is single lane in both directions and operates under a posted speed limit of 50km/h. 3.3.5.3 Daily Traffic Flows Data on traffic flow was collected by Seca Solutions on Woodburn-Evans Head road. Surveys were conducted between 7.30 am and 9.30 am and 2.30 pm and 6.00 pm on the 12th December 2014. Peak flow was recorded as 266 vehicles per hour. It was calculated that daily flows would be approximately 2 700 vehicles per day. 3.3.6 Noise At present, Evans Head is a low movement aerodrome. The Great Eastern Fly-In occurs every January and is a two-and-a-half day event that celebrates the World War II heritage of the aerodrome. 3.3.6.1 ANEF Contours and Planning Controls The Australian Noise Exposure Forecast (ANEF) is a complex average of annual aircraft movements. The average is based on a rating of each aircraft event which occurs in a year, with noise adjustments applied to movements which occur outside the period 07:00-19:00 hours. ANEF contours with a value higher than 25 are considered incompatible with residential development, whilst areas below 20 are considered acceptable for residential development. Between 20 and 25, residential developments should only be permitted with the incorporation of suitable noise reduction features. The boundary of the south-eastern area which is currently zoned residential is approximately 60 metres outside the 20 ANEF contour. Per the Australian Standard AS 2021, development, which is compatible with the area’s existing zoning would be permissible. 3.3.6.2 Existing Noise Levels Ambient noise monitoring between the 27th February 2015 and the 9th March 2015 occurred at three locations within the aerodrome to establish the existing noise environment. The summary of measure noise levels are shown in Table 2 Evans Head Airpark – Statement of Environmental Effects Page 34 Table 2: Summary of Measured Noise Levels during Whole Monitoring Period NOISE DESCRIPTOR LAMAX LAeq, 15 minute Average LA10, 15 minute Average LA90, 15 minute 10th percentile Average RBL TIME PERIOD MONITORING LOCATION 1 MONITORING LOCATION 2 MONITORING LOCATION 3 91.2 24-hour 79.3 102.8 Day (7am to 6pm) 50.0 58.2 49.2 Evening (6pm to 10pm) 47.9 50.0 44.6 Night (10pm to 7am) 47.5 44.3 44.6 Day (7am to 6pm) 50.7 52.0 48.9 Evening (6pm to 10pm) 49.4 54.1 46.6 Night (10pm to 7am) 49.7 44.5 44.4 Day (7am to 6pm) 35.4 33.0 34.8 Evening (6pm to 10pm) 37.3 38.5 37.5 Night (10pm to 7am) 36.1 38.1 37.7 Day (7am to 6pm) 38.9 39.6 39.1 Evening (6pm to 10pm) 38.4 39.8 38.9 Night (10pm to 7am) 38.9 39.6 39.3 Evans Head Airpark – Statement of Environmental Effects Page 35 LAeq, 15 minute is considered to be the best descriptor for human perception of sound pressure level over each monitoring period. The difference between the monitoring locations was 0.3-9 dB(A) depending on the time of day. Flight movements during the monitoring period were recorded with their time of arrival or departure, runaway and type of craft. The noise level for each aircraft movement was also recorded – refer Appendix D. The National Airports Safeguarding Framework states that Zoning for noisesensitive development should be avoided where ultimate capacity or long range noise modelling for the airport indicates either: 20 or more daily LASmax events greater than 70 dB(A); 50 or more daily LASmax events greater than 65 dB(A); or 100 events or more daily LASmax events of greater than 60 dB(A) It was determined that the current flight operations as measured at site comply with the above National Airports Safeguarding Framework criteria. 3.3.7 Ecology Peter Parker Environment Consultants Pty Ltd (PPEC) was engaged to undertake a Flora and Fauna Assessment of the site. The report is contained in Appendix E. Previous site assessments were undertaken by Peter Parker in 2001, 2004 and 2010 and by Geolink in 2010 (PPEC, 2014). 3.3.7.1 Field Surveys Field surveys were undertaken by PPEC over four (4) days in May 2014. Vegetation was surveyed using meandering transects. The adopted vegetation classification system was Keith’s Open Shores to Desert Dunes: the native vegetation of NSW and the ACT (2004) and Walker and Hopkins’s Vegetation in Australian soil and land survey field (1990). The Biometric Vegetation Classification for the Northern Rivers Catchment Management Area includes a vegetation type identification code. The following features were recorded: Dominant trees, shrubs and ground covers in each strata; Major plant species in the association; Tree heights and foliage cover; and Any threatened species. Evans Head Airpark – Statement of Environmental Effects Page 36 Fauna surveys included the trapping and database review based on the vegetation recorded at the site and relevant local records. Threatened species known in the area were targeted in the fauna survey. The surveys were undertaken over four (4) nights from 19th to 23rd May 2014. Hair-tube trapping occurred over ten (10) nights between 19th and 30th May 2014. The survey methods used include: Mist nets and acoustical detection devices were set in flyways for megachiropteran and microchiropteran bats; “A” and “B” Elliott traps and cage traps were set in a variety of forest types and ecotones. The “B” Elliott traps were attached to trees using tree-brackets or placed in log piles; Hair-tube traps and spotlighting was used in association with other survey methods to identify the presence of larger vertebrates. Ten (10) hair-tube traps were also set in trees to attract blossom bats. These were baited with peanut butter, oats and honey and sprayed daily with a sugar solution; Pit-fall traps were used to capture small mammals, frogs and reptiles; and Trail cameras were set up along transect lines and near bait stations. A variety of meat and vegetable baits were used to attract fauna. Survey methods and trap locations are depicted in Figure 12. Reptiles were searched for opportunistically in suitable habitats (e.g. among leaf litter and under logs). Frogs were identified by call, pit-fall captures or observations. Survey locations included creek-lines, ponding adjacent to the runway and roadside drains (refer Figure 16). Birds were identified visually and aurally during post-dawn and evening transects. Transects of approximately 40 minutes duration were undertaken each morning. Birds were also recorded during the vegetation and fauna survey and follow up surveys. Play-back calls were used to identify the presence of cryptic or nocturnal species. Calls of the masked owl, grass owl, powerful owl, bush hen and bush stone curlew were broadcast shortly after dusk on each survey night. Calls of the ground parrot were broadcast in the north of the site on sunset. Calls were broadcast over a 15 minute period in sequences of approximately three minutes on and two minutes off. Evans Head Airpark – Statement of Environmental Effects Page 37 The mammal survey used a spotlight, Elliott “A” and “B” traps, hair-tube traps, cage traps, harp-nets, mist nets, ultrasonic detection devices (Anabat II and Songmeter), play-back calls (for birds) and collections of scats and skeletons. Trail cameras were also used as were pit-fall traps Nocturnal searching using a hand-held 100-watt spotlight was undertaken along the trap-line transects and along tracks within and around the site over four (4) nights. Spotlighting from a vehicle was also carried out using two observers along the airport runway, tracks and local road network. Opportunistic daytime litter searching occurred for scats, skeletons, reptiles, frogs and skinks. Survey sites included roadside drains, under logs and amongst litter along tracks. Surveys also included searches for koala scats under forest redgum Eucalyptus tereticornis, a recognised koala food tree. Megachiropteran and microchiropteran bats were searched for using harpnets, mist nets, ultrasonic detection devices (Anabat II and Songmeter) and a spotlight. Three (3) Anabat II detection devices and one (1) Songwriter were used to record bat ultrasound in a variety of habitats which included potential flyways over banksia and paperbark shrubland and open grassland. This effort is equivalent to 16 acoustical detector nights (i.e. 4 nights x 4 detection devices). One of the detectors was used as a hand-held device during the spotlight transects and then set in a stationery location for the remainder of the night. Bat calls were recorded onto a digital flash card for later analysis. Spotlighting for microchiropteran bats and flying-foxes as well as other fauna species was undertaken in potential food trees and by call identification over four (4) nights for approximately two hours/night. Call detection for frogs was undertaken opportunistically. Fish surveys were undertaken in a small stream located south of the site using baited fish traps and a dip net (referFigure 13). Traps were spaced at 10 to 30 metre intervals along the drainage line which commences under the Woodburn-Evans Head Road. Eight (8) fish traps were set on 19th May 2014 and retrieved on 20th May 2014. Native fish were retrieved, identified and released back into the creek. A previous survey at this location (Parker 2010) used ten (10) fish traps over three (3) nights from 6th to 8th December 2010. On the 2010 survey, traps were inspected each morning (7th, 8th and 9th December 2010), rebaited and native fish were retrieved, identified and released back into the creek. Evans Head Airpark – Statement of Environmental Effects Page 38 Figure 12: Fauna Survey Methods & Locations Evans Head Airpark – Statement of Environmental Effects Page 39 Figure 13: Fish Survey and Location of Baited Fish Traps Evans Head Airpark – Statement of Environmental Effects Page 40 3.3.7.2 Flora PPEC has identified seven (7) vegetation associations in three (3) communities. These communities are: Woodland; Shrubland; and Grassland. The location of the vegetation associations is depicted in Figure 14. The Woodland consists of: A 6.8 ha area of broad-leaved paperbark (Melaleuca quinquenervia), heath-leaf banksia (Banksia ericifolia var. macrantha) and wallum banksia (Banksia aemula). These plants are typically located in areas with a high watertable and along drainage lines though they were located throughout the site. The broad-leafed paperbark is a common species and this association is locally common and conserved in both the Broadwater and Bundjalung National Parks. A small area (0.16 ha) of forest redgum (Eucalyptus tereticornis) located on the edge of the runway. Forest redgum is locally important as a koala food tree although no evidence of the koala (observations, scats or scratches) was recorded at the site. Two areas of swamp box (Lophostemon suaveolens), forest redgum (Eucalyptus tereticornis) and broad-leaved paperbark (Melaleuca quinquenervia) are located on the site. A 1.7 ha area located north of the airport runway and a 2 ha area within the proposed eastern development precinct (2 ha). Swamp box, like broad-leaved paperbark, is a common floodplain species. The 2 ha component of this association supports several mature forest redgum which were not represented elsewhere at the site. No evidence of koala occurring in this association was observed. Mature forest redgum are well represented locally at Iron Gates located several kilometres to the south of the site and adjacent to the Evans River. Evans Head Airpark – Statement of Environmental Effects Page 41 The Shrubland is tall open shrubland and consists of: A 5.3 ha area of Brush iron-bark wattle (Acacia disparrima subsp. Disparrima) and broad-leaved paperbark (Melaleuca quinquenervia). Brush iron-bark wattle is a common regrowth species in the Evans Head locality being recorded mainly along the coast and extending north from the Bellinger River into Queensland. This species occurs in woodland, wet sclerophyll forest, on margins of rainforest and behind coastal sand dunes. This association is scattered throughout the site, particularly along the runway margins and along the Woodburn-Evans Head Road. It is particularly common locally. A 98 ha area of heath-leaf banksia, broad-leaved paperbark, (Melaleuca nodosa), prickly tea tree within mid-high open shrubland. The northern part of the site has not experienced bushfire for over a decade and the southern part of the site for a considerably longer period. Evans Head Airpark – Statement of Environmental Effects Page 42 Figure 14: Vegetation Associations Evans Head Airpark – Statement of Environmental Effects Page 43 Plants and vegetation of conservation significance No threatened plant species or Endangered Ecological Community (EEC) was recorded at the site. The NSW Office of Environment and Heritage’s (OEH) Wildlife Atlas maps a number of threatened plant species within five (5) kilometres of the site: Heath wrinklewort (Rutidosis heterogama), grows mostly in heath, often along disturbed roadsides. It occurs chiefly in coastal districts from Maclean to the Hunter Valley, and inland to Torrington. It is a small perennial herb to 30 cm tall, with a woody base bearing sparse upright, or sometimes horizontal, branches with upright shoots at the end. This is a relatively conspicuous species which occurs in the Yuraygir and Bundjalung National Parks. It may potentially occur but was not recorded during the survey; Needle-leaf fern (Belvisia mucronata). This species is epiphytic or lithophytic in rainforest or along creeks in moist open forest. Usually found in small clumps on trees or rocks in rainforest. It is unlikely to occur at the site due to the absence of rainforest; Red-flowered king of the fairies (Oberonia titania). This species is a small orchid which grows on trees and rocks. It occurs in littoral and subtropical rainforest, paperbark swamps, and eucalypt-forested gorges and mangroves. This species could potentially occur in the broad-leaved paperbark association; and Water nut grass (Cyperus aquatilis), occurs north from Evans Head and grows in ephemerally wet areas. Suitable habitat occurs in the north of the site in the area mapped prickly tea tree, zig-zag bog rush. Evans Head Airpark – Statement of Environmental Effects Page 44 3.3.7.3 Fauna PPEC states that threatened fauna species are well represented in the Evans Head locality due to the presence of habitats of high conservation value (e.g. Broadwater and Bundjalung National Parks). Reptiles and Amphibians Few reptiles were recorded at the site in the 2014 survey or on previous surveys. This result is somewhat problematic as the habitats at the site are suitable for a wide range of species. Two (2) species; the eastern grass skink (Lampropholis delicata) were recorded in all vegetation associations but were not abundant and the green tree snake (Dendrelaphis punctulata), was recorded in the broad-leaved paperbark woodland. Four (4) frog species were recorded in the 2014 survey. These were the common froglet (Crinia signifera), the rocket frog (Litoria nasuta), the northern banjo frog (Limnodynastes terraereginae) and the introduced cane toad (Chaunus marinus). Suitable habitat for the wallum sedgefrog (Litoria olongburensis) and the wallum froglet (Crinia tinnula) was recorded north of the site where these species were recorded by Parker (2001). However, neither of these species were detected during the 2014 survey. Birds The site supported large numbers honeyeaters due to the prolific blossoming of heath-leaf banksia and broad-leaved paperbark. Common species included the noisy friarbird (Philemon corniculatus), the white-throated honeyeater (Melithreptus Albogularis), the brush wattlebird (Anthochaera chrysoptera), the brown honeyeater (Lichmera indistincta) and Lewin's honeyeater (Meliphaga lewinii). Characteristic “open country” species included the rainbow lorikeet (Trichoglossus haematodus), the scaly-breasted lorikeet (Trichoglossus chlorolepiotus), the Australian magpie (Gymnorhina tibicen), and the torresian crow (Corvus orru). Richard’s pipit (Anthus richardi) was common on the grassland adjacent to the airport runways as was the masked lapwing (Vanellus miles). A number of raptors were recorded on most survey days. These included the Australian kestrel (Falco cenchroides) and the vulnerable square-tailed kite (Lophoictinia isura). Bird abundance and species-richness is expected to vary throughout the year. However, the peak of honeyeater activity was noted during the May 2014 survey due to the proliferation of flowering trees and shrubs. Evans Head Airpark – Statement of Environmental Effects Page 45 Severable vulnerable bird species have previously been recorded adjacent to the site in 2001. One additional species, the square-tailed kite was recorded during the 2014 survey. Mammals The 2001 and 2014 surveys included trapping for small and medium size mammals, spotlighting and call detection. Two (2) large macropods, the eastern grey kangaroo (Macropus giganteus) and the swamp wallaby (Wallabia bicolor), were recorded grazing at the site in previous surveys (Parker 2001; 2004) and both were recorded in the 2014 survey. The Elliott, cage and pit-fall traps all yielded poor results in 2014. The bush rat (Rattus fuscipes) was the only species of small mammal captured and was captured in Elliott traps along both transects. However, only nine (9) individuals were captured over the entire survey period. The cage traps failed to capture any fauna despite the presence of the long-nosed bandicoot (Perameles nasuta), being detected by the fauna camera and the northern brown bandicoot (Isoodon macrourus) in hair-tune traps. The swamp wallaby, northern brown bandicoot and the grasslands melomys (Melomys burtoni) were recorded using hair-tube traps. Koalas The koala is known within the study area, particularly at Iron Gates to the south of the site. However, it was not recorded during any of the Parker fauna surveys and no evidence of scats was detected under forest redgum (a koala food tree). Spotlighting was unsuccessful in detecting any arboreal mammals. Bats A total of 848 recognisable calls were recorded throughout the 2014 survey. Ten (10) bat species were identified. They include: Long-eared bat (Nyctophilus sp.); Eastern broad-nosed bat (Scotorepens orion); Eastern false pipistrelle (Falsistrellus tasmaniensis); Eastern forest bat (Vespadelus pumilus); Eastern horse-shoe bat (Rhinolophus megaphyllus); Gould’s wattled bat (Chalinolobus gouldii); Grey-headed flying fox (Pteropus poliocephalus); Little bent-wing bat (Miniopterus australis); Little broad-nosed bat (Scotorepens greyii); and Evans Head Airpark – Statement of Environmental Effects Page 46 Little forest bat (Vespadelus vulturnus). Three bat species recorded in 2014 are listed as vulnerable. 3.3.7.4 Fish Fish species were recorded downstream from the study site on the southern side of Woodburn-Evans Head Road (refer Figure 13). Three (3) fish species were recorded in the 2010 survey and two (2) species in the 2014 survey. The introduced mosquito fish, which was recorded in the 2010 survey, is listed as a threatening process pursuant to the Threatened Species Conservation Act. The striped gudgeon (Gobiomorphus australis) and the firetail gudgeon (Hypseleotris galii) are both relatively common native species in east coast Australian freshwater streams. Their presence suggests that the habitat quality is high. These species are found in habitats where the Oxleyan pygmy perch may occur. The Oxleyan pygmy perch was recorded in 1998 and 1999 in a small drain near the Woodburn-Evans Head Road. A more intensive survey of this area in 2000 resulted in the capture of 566 pygmy perch from 25 water bodies in and around Broadwater National Park. Surveys undertaken in 2001-02 recorded seven new locations close to Broadwater and Bundjalung National Parks, including some on private property and on Aboriginal land. While the Oxleyan pygmy perch was not recorded during the fish survey conducted for this proposal, this may be explained by population fluctuations rather than lack of habitat suitability. For example, the Oxleyan pygmy perch was recorded in Lake Hiawatha, Tick Gate, Swamp and Wooli Creeks in the 1970s, but not again in those area until 1995 (NSW DPI, 2005). Similarly, it was recorded in Blue Lagoon on Moreton Island in 1976, then not again until 2000, despite surveys in 1982, 1990 and 1993 (NSW DPI, 2005). PPEC refers to an illustration within a report prepared by Geolink in 2010. The report was for the ecological assessment for the Remediation Works at Evans Head Aerodrome. This illustration shows the local distribution of known, potential and unlikely Oxleyan pygmy perch habitat. The illustration is reproduced herein as Figure 15. Evans Head Airpark – Statement of Environmental Effects Page 47 Figure 15: Local distribution of known, potential and unlikely Oxleyan pygmy perch habitat Evans Head Airpark – Statement of Environmental Effects Page 48 3.3.7.5 Recorded Threatened Species The surveys undertaken by Parker in 2001, 2004 and 2014 recorded the following threatened species: Two (2) frogs: the wallum froglet (Crinia tinnula) and the wallum sedgefrog (Litoria olongburensis); Six (6) birds: the bush-hen (Amaurornis olivaceus) the glossy black cockatoo (Calyptorhynchus lathami), the osprey (Pandion haliaetus), the ground parrot (Pezoporus wallicus) the eastern grass owl (Tyto capensis) the square-tailed kite (Lophoictinia isura); and Seven (7) bats: the hoary bat (Chalinolobus nigrogriseus), the little bent-wing bat (Miniopteris australis), the large-footed myotis (Myotis adversus), the yellow-the bellied sheath-tail bat (Saccolaimus flaviventris), the eastern false pipistrelle (Falsistrellus tasmaniensis), the grey-headed flying fox (Pteropus poliocephalus) and the common blossom bat (Syconycteris australis). The common planigale (Planigale maculate), was recorded on lands adjacent to the aerodrome in 1998 and the endangered Oxleyan pygmy perch (Nannoperca oxleyana) was recorded in 2000 in a drainage line south of the Evans Head to Woodburn Road. The locations of the recorded threatened species are depicted in Figure 16. The number of threatened species is not surprising given that the Broadwater National Park occurs within the study area. Species recorded within the National Park but not within the site include the ground parrot, the bush hen, the wallum froglet and the wallum sedgefrog. Many of the species listed above are wide-ranging and were recorded while passing over or through the site (e.g., the osprey, the square-tailed kite, the glossy black cockatoo and the bats. Moreover, the site does not provide critical habitat for any of the species recorded during the 2001 or the 2014 fauna surveys. The habitat at the site provides foraging sites, nesting sites, and sheltering sites and is part of a larger area which includes the Broadwater and Bundjalung National Parks and surrounding privately owned lands. The Oxleyan pygmy perch was not recorded during the fish survey. This may be explained by population fluctuations rather than lack of habitat suitability. In NSW, the Oxleyan pygmy perch is recorded at sites with wide-ranging and variable water quality. Evans Head Airpark – Statement of Environmental Effects Page 49 Figure 16: Threatened species recorded within study area Evans Head Airpark – Statement of Environmental Effects Page 50 Contamination Several previous contamination reports have been carried out on the site. Mr. Mark Imber of MTNKR Consulting was engaged to review previous reports and identify any potential issues with the site. 3.4.1 Potentially Contaminating Activities During the use of the aerodrome by the RAAF, several potentially contaminating activities occurred, including: 10,000 gallon petrol tanks; 1,000 gallon oil tanks; Petrol Bowser; Incinerator; Workshops; Boiler house; Pyrotechnics store; Blacksmith; and Armoury. Following its use by the RAAF, the Richmond Valley Council took ownership of the aerodrome in the 1950’s with parts of the site being utilised as a council depot from 1983. During its use by council, potentially contaminating activities include: Vehicle storage; Plant storage; Offices; Chemical storage – herbicides; Paint and solvent storage; Sand blasting; Wash down bay; Machinery workshop; Bulk materials storage; Machinery component storage; Evans Head Airpark – Statement of Environmental Effects Page 51 Pipeline storage; Fuel storage and refuelling; Waste oil storage; and Temporary waste transfer location for construction materials. A site walkover in 2005 by council noted the following: Staining at the petrol bowsers, the waste oil handling area and the historical waste oil area (southwest of the bowsers adjacent to the workshop); Pieces of timber, fill and concrete were stored at the boundary to the airfield; Surface water drainage lines were present at the site, leading the water onto the Airfield Site; The drainage network under the depot was connected to a sump that had been used as general washdown for wastes such as oils, solvents, paints etc at the depot. The sump was located at the historical waste oil area to the southwest of the bowsers adjacent to the workshop. The drainage network leads into the main drain and goes into the SEPP14 Wetland; Herbicides used were Round Up Bi Active (“frog friendly”); and Stockpiles of road base material was stored on site. Numerous site investigation reports and remediation plans have been carried out for the site as seen in Table 3. The two primary testing areas were the council depot with adjacent airfield which constitutes the ‘Aged Care Facility Site’. The second area is the ‘Vacant Industrial Site’.

Despite this, it is important to note that the Old Council Depot site and the adjoining land to the south and south east are outside of the development boundary. As such, no development will occur on this land. 3.4.2 Cultural Heritage Reviews of World, Federal, State and Local Heritage databases and plans have been consulted to identify and European or Indigenous heritage items or places occurring in or adjacent to the proposal site. 3.4.2.1 Local Heritage The Richmond Valley Local Environmental Plan 2012 has a list of identified Heritage Items outlined in Schedule 5. Schedule 5 was consulted to determine if there were any locally listed heritage items within the Evans Head area. A total of seventeen (17) heritage places were identified, as detailed in Table 4.

The search tool has been consulted for listings occurring within the Evans Area. A single State listed heritage listing was returned for the Evans Head Area – this being the Evans Head Memorial Aerodrome. No other items of State Heritage Significance in the Evans Head area have been identified. Evans Head Airpark – Statement of Environmental Effects Page 60 3.4.2.3 Federal Heritage Sites and places determined to be heritage items under the Environment Protection and Biodiversity Conservation Act 1999 are listed on the Department of the Environment Australian Heritage Database. The database has been consulted for listings occurring within the Evans Head area. Four (4) commonwealth listed heritage places have been identified using the search tool. The identified heritage places are outlined in Table 5. Table 5: Commonwealth Listed Heritage Places – Evans Head HERITAGE PLACE SIGNIFICANCE RELEVANT NOTES Broadwater National Park (1978 boundary) Pacific Hwy Natural – Register of the National Estate (Non Statutory) The sand plains of Broadwater National Park stretching inland up to 10 km are of great scientific interest in the study of the geomorphology of the east coast. Research has also been carried out on the paleobotany of the area highlighting climatic change. There is a great diversity of plant communities (five scrub/heath, six swamp communities). Indigenous Place Indigenous– Register of the National Estate (Non Statutory) Limited details provided Indigenous Place Indigenous– Register of the National Estate (Non Statutory) Limited details provided Natural– Register of the National Estate (Non Statutory) The Jerusalem Creek Area contains extensive representations of coastal heath and scrub vegetation and extensive swamp forest, as well as a diversity of other vegetation types. The area is valuable for its geological and geomorphological features, distinctive indigenous vegetation (mangroves, sedgelands, heaths, woodlands, sclerophyll forests) and pristine waterways. Jerusalem Creek Area It should be noted that while the location of the two natural heritage items are known (and do not occur within the proposed development area) the locations of the indigenous listings have not been detailed. Indigenous Heritage is discussed further in Section 3.4.2.5. Evans Head Airpark – Statement of Environmental Effects Page 61 3.4.2.4 World Heritage Sites and Places deemed to be of world heritage significance are listed by the United Nations Educational, Scientific and Cultural Organisation (UNSECO). The UNESCO World Heritage list was consulted to determine if there were any listed heritage sites within the Evans Head area. It was determined that there were no world heritage listings relevant to the Evans Head area. 3.4.2.5 Protection of Aboriginal Cultural Heritage Aboriginal sites within NSW are protected under the National Parks and Wildlife Act 1974 and National Parks and Wildlife Regulation 2009. Under this Act, all Aboriginal objects are protected regardless of their significance or land tenure. It also protects Aboriginal places that may or may not contain Aboriginal objects. This Act outlines the ‘Due Diligence’ process that serves to provide a framework for identifying potential objects or sites of significance. This process minimises the likelihood of Aboriginal objects or sites being damaged or affected by development. An Aboriginal Heritage Information Management System (AHIMS) database search was undertaken on the 3rd February 2016. The search did not identify any Aboriginal sites within a 200 metre radius of the proposed development site. A copy of the search results is included in Appendix CAppendix A. The NSW Department of Environment, Climate Change & Water Due Diligence Code of Practice for the Protection of Aboriginal Objects in NSW provides guidance as to when a cultural heritage consultant should be engaged. The code details that proposed activities within 200 metres of waters on land that is not disturbed land must be subject to specialist assessment. The proposed development site is consistent with these criteria and subsequently will be required to be subject to specialist assessment. 3.4.3 Coastal Surface Water Evans Head township is part of the NSW Evans River Catchment. The Evans River is a small coastal catchment of approximately 62 km2 and enters the ocean at the township of Evans Head. Most of the catchment area is located within the Bunjulung and Broadwater National Parks and is largely unmodified (NSW Office of Water, 2010). Flows into the river during dry periods are generally low. Daily tidal currents flush the lower reaches of the river and results in generally good quality water near the river mouth (Hartley Associates International, 2006). However, water quality can be affected by the flow inputs from the Richmond River catchment via the Tuckombil Canal upstream. Evans Head Airpark – Statement of Environmental Effects Page 62 The Evans River surface water is managed under the Water Sharing Plan for the Richmond River Area Unregulated, Regulated and Alluvial Water Sources 2010. There are no surface water entitlements current for the subject site under this Plan. The subject site is positioned in the low-lying areas of the catchment, where wetlands and flooding is prevalent. The topography of the subject site can be classified as relatively flat with an average elevation of six (6) metres and negligible slope. Surface water from the airport site does not flow freely from the site. The north-western corner of the site is an ephemeral wetland area that captures runoff from the northern part of the site. The southern part of the site flows to the south of the site to a low-lying area near Woodburn-Evans Head Road. In the event of heavy rainfall and flood conditions, the site drains to the Evans River to the south of the site. 3.4.4 Wetlands There is a wetland located to the north of the development site. This will remain outside the development footprint with no plans to alter or encroach upon the wetland. 3.4.5 Coastal Groundwater The groundwater sources within the Evans Head region are dominated by porous rocks of the Woodburn Sand Units and the South Casino Gravel aquifers that are part of the regional flow system of the Clarence Moreton Basin. The sand and gravel geology of the area facilitates large volumes of groundwater flows and effective infiltration after rainfall events. Groundwater around the Evans Head township is generally very shallow and fluctuates due to local rainfall infiltration and regional groundwater movement (Hartley Associates International, 2006). Based on prior fieldwork, local groundwater is expected to be perched in natural sand. Groundwater was estimated to flow mainly in an easterly – north easterly direction and be located at approximately 1 – 2 mbgs. The estimated gradient was 0.005 metres per minute (m/m) and the non-retarded groundwater flow was estimated to be 0.025 metres per day The Evans River groundwater is managed under the Water Sharing Plan for the Richmond River Area Unregulated, Regulated and Alluvial Water Sources 2010. There are no groundwater entitlements current for the subject site under this Plan. There are no identified high priority groundwater dependant ecosystems located on the subject property as outlined by this document. Evans Head Airpark – Statement of Environmental Effects Page 63 A desktop hydrology study was undertaken to identify the groundwater bore receptors in proximity to the proposed subject site. The findings of this investigation are summarised below in Table 6. The groundwater works summaries for these bores can be found in Appendix A. There is one groundwater bore located on the subject site that was used as a dewatering bore. This groundwater bore is 3 m deep, and no water bearing zones were reported on the groundwater works summary. A number of the other groundwater bores listed are monitoring bores for the Evans Head Sewage Treatment Plant (GW305384, GW306411, GW306412, GW306413, GW306414, and GW306415).

Tuckombil Canal was constructed in the early 1900’s and enlarged in 1965 to reduce the flood impacts on the Richmond River downstream areas. The Evans River significant flood events are dominated by large events on the Richmond River overtopping the Tuckombil Canal weir. Significant flood events have occurred in 1954 and 1974. The 1974 flood was noted as being particularly severe as it occurred during high spring tides. Generally, flooding occurs within the Evans Head township area due to local catchment runoff, storm surge and Richmond River overflow. High intensity, short duration rainfall has the potential to cause localised flooding within the township area. The flooding is generally short-term and due to the waters draining into the Evans River. Large storm surges from low pressure systems can result in flooding of low-lying areas due to the proximity of the area to the ocean (BMT WBM, 2014). The site is not specifically identified as a flood prone area as per the Richmond Valley Flood Mapping map (BMT WBM, 2010) or the Evans River Flood Study (BMT WBM, 2014). The Richmond Valley LEP 2012 also does not specifically identify the subject site as flood prone. However, due to the site’s proximity to the ocean and to the Evans River, flooding will be considered as part of this assessment. 3.4.7 Bushfire The site is identified as bushfire prone land as per the NSW Rural Fire Service mapping for the Richmond Valley LGA (July 2003). A full Bushfire Assessment Report has been included in Appendix I of this document for referral to the NSW Rural Fire Service. The vegetation type within the proposed development site is characterised by ‘tall heath (scrub)’. There are large areas which are free of canopy or shrub vegetation and the groundcover is maintained (predominantly in areas surrounding the existing runways). Vegetation formations immediately surrounding (within 140 metres) the proposed development areas range from saline wetlands (a single, small patch) to tall heath and forests. There are a number of areas within the proposed development site that are identified as non-vegetated areas and areas of reduced vegetation. These areas are not considered to pose a bushfire hazard. Non-vegetated areas and areas of reduced vegetation within 140 metres of the proposed development site include: Runways and associated grassed buffer areas; Bitumen aprons and taxi-ways; Evans Head Airpark – Statement of Environmental Effects Page 65 Residential dwellings and associated gardens; Roads and managed road reserves; and Industrial development and associated gardens. The subject site has been identified as a potential bushfire risk (Category 1 – greater than 1 hectare of vegetation type 1 or 2). A number of mitigation measures have been discussed in further detail within the Bushfire Assessment report. Evans Head Airpark – Statement of Environmental Effects Page 66 Planning Regulatory Framework Background This section outlines the environmental and planning legislative framework relevant to the proposed development. This section describes the environmental assessment process under the Environmental Planning and Assessment Act 1979 (EP&A Act) and other relevant environmental planning instruments pertaining to the development. The approval pathway is identified under Part 4 of the EP&A Act and is outlined in more detail in Section Project Definition The Richmond Valley LEP 2012 dictionary defines an airport to mean: a place that is used for the landing, taking off, parking, maintenance or repair of aeroplanes, and includes associated buildings, installations, facilities and movement areas and any heliport that is part of the airport The site is referenced in the Richmond Valley LEP 2012 (RVLEP 2012) in cl 6.11 Airspace operations and cl 6.12 Development in areas subject to aircraft noise as Evans Head Airport. The current land usage for the Evans Head Memorial Aerodrome can therefore be defined as an airport. Environment Protection and Biodiversity Conservation Act 1999 The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) is administered by the Commonwealth Department of the Environment (DOE) and provides a legal framework to protect and manage nationally important flora, fauna, ecological communities and heritage places defined as matters of national environmental significance (MNES). The existing site has been subject to an ecological assessment to determine the presence of MNES within the site (refer to Section 5.6 Ecology). It has been determined that impacts on MNES resulting from the development are deemed to be unlikely. Subsequently, referral of the project under the EPBC Act is not required. Evans Head Airpark – Statement of Environmental Effects Page 67 Environmental Planning and Assessment Act 1979 The Environmental Planning & Assessment Act 1979 (EP&A Act) is the NSW Government’s key piece of legislation for the management of our environment and resource use, in relation to planning and development. The proposed development requires consideration under S. 79C of the EP & A Act. 4.4.1 Objectives of the EP&A Act 1979 The objects of the EP&A Act are: (a) To encourage: (i) the proper management, development and conservation of natural and artificial resources, including agricultural land, natural areas, forests, minerals, water, cities, towns and villages for the purpose of promoting the social and economic welfare of the community and a better environment, (ii) the promotion and co-ordination of the orderly and economic use and development of land, (iii) the protection, provision and co-ordination of communication and utility services, (iv) the provision of land for public purposes, (v) the provision and co-ordination of community services and facilities, and (vi) the protection of the environment, including the protection and conservation of native animals and plants, including threatened species, populations and ecological communities, and their habitats, and (vii) ecologically sustainable development, and (viii) the provision and maintenance of affordable housing, and (b) to promote the sharing of the responsibility for environmental planning between the different levels of government in the State, and (c) to provide increased opportunity for public involvement and participation in environmental planning and assessment. Through the preparation of this Statement of Environmental Effects, the project’s consistency with the objectives of the Act has been clearly demonstrated. Evans Head Airpark – Statement of Environmental Effects Page 68 Permissibility & Consent 4.5.1 State Environmental Planning Policy (Infrastructure) 2007 The site is a functioning aerodrome. The NSW State Environmental Planning Policy (Infrastructure) 2007 permits construction works, fencing, drainage, and vegetation management by or on behalf of a public authority. It also permits development if the development is ancillary to the air transport facility for: passenger terminals; freight storage, receival and forwarding; hangars for aircraft storage, maintenance and repair; and premises for retail, business, recreational, residential or industrial use. The development specifically seeks approval as an ancillary development to an air transport facility. SEPP Infrastructure allows for ancillary business, residential and industrial uses to an air transport facility to be permitted with consent. The SEPP therefore permits all of the intended airpark activities on Lot 3 in DP 1217074. 4.5.2 Lot size Reference to the lot size maps for the RVLEP 2012 indicate two minimum lot size areas for RU1 and E3 zoned land and for IN1 and R1 zoned land: RU1 and E3 minimum lot size is 40 ha for AB land; and IN1 and R1 minimum lot size is 750m2 for R land. 4.5.3 LEP Heritage Incentive Clause Whilst SEPP (Infrastructure) 2007 permits the airpark development, subdivision of the site is not permitted unless the minimum lot size conforms to Clause 4.1 of the RVLEP 2012 and the Minimum Lot Size Map for the relevant zone. The heritage incentive clause 5.10(10) of the RVLEP 2010 permits any use of the land if it leads to the conservation of the heritage item. Allotments are mentioned in heritage management plan. As the proposed community title subdivision will create a funding source, via annual levies, to pay for the use and management of the air facilities, the subdivision of the land is deemed to be permissible. Evans Head Airpark – Statement of Environmental Effects Page 69 Environmental Planning and Assessment Regulation 2000 The following is an assessment of the possible triggers for designated development under Schedule 3 of the Environmental Planning and Assessment Regulation 2000. 4.6.1.1 Clause 2 Aircraft facilities – Part 1 This clause does not apply as the development is not for a proposed aircraft facility. Development approval is sought for an integrated residential, industrial and commercial aviation development as ancillary development to an existing air transport facility. 4.6.1.2 Clause 37A Ancillary development – Part 3 This part of Schedule 3 of the regulation addresses what is excepted from designated development. Development of a kind specified in Part 1 is not designated development if (a) it is ancillary to other development, and (b) it is not proposed to be carried out independently of that other development. For this development, development approval is sought for an integrated residential, industrial and commercial aviation development as ancillary development to the existing air transport facility. 4.6.1.3 Clause 15 Contaminated soil treatment works – Part 1 It is our understanding a stockpile of approximate 3,000 to 4,000 cubic metres in volume is located on the site. We have sought confirmation of this volume from Mr Mark Imber from MTNKR Consulting the author of the initial contamination review (2010). We further understand the material originated from the remediation works undertaken on the Council controlled site to the southeast (now Lot 1 in DP 1193927). As the land parcel was formerly part of the airfield site, it can be classified as having originated from the site. Sub-clause (a) refers to material not originating from the site on which the development is proposed. The listed thresholds within this sub-clause do not apply due to the origin of the material. Similarly sub-clause (b) is not applicable. There is no intention for the development to treat 1,000 cubic metres of contaminated soil not originating from the site. Evans Head Airpark – Statement of Environmental Effects Page 70 The last sub-clause (c) is the most relevant. Contaminated soil is located on the site that originated from the site. The development will: Not incinerate 1,000 cubic metres of contaminated store per year; Not treat and store more than 30,000 cubic metres of contaminated soil; or Not disturb more than an aggregate area of 3 hectares of contaminated soil. Finally, it is noted that the development is not a Contamination Soil Treatment Works but rather an integrated residential, industrial and commercial aviation development as ancillary development to an existing air transport facility. 4.6.2 Integrated development – s91 Environmental Planning and Assessment Act 1979 It is understood integrated development approval will need to be obtained from other public authorities (e.g. the EPA) before consent can be granted for: Heritage Act 1977; Road Act 1993; and Rural Fires Act 1997. NSW Environmental Planning Instruments There is a number of State Environmental Planning Policies (SEPP) that are considered relevant to the project which includes: SEPP Infrastructure 2007; SEPP 44 – Koala Habitat; SEPP 55 – Remediation of Land; and SEPP 71 – Coastal Protection. SEPP Infrastructure has been discussed in Section 4.5.1 whilst SEPP 44 is addressed in Section 5.6 Ecology. The remaining SEPPs are addressed in the following sections. Evans Head Airpark – Statement of Environmental Effects Page 71 4.7.1 State Environmental Planning Policy 55 – Remediation of Land It is understood that several contamination assessments and remedial action plans have been developed for the site. An Initial Contamination Review was undertaken by MTNKR Consulting’s Mr Mark Imber. We have engaged Mr Imber to address contamination especially with respect to designated development triggers. Mr. Imber has also reviewed all previous site works and remedial plans to assist in the development of an appropriate course of action. This is discussed further in Section 5.7. 4.7.2 State Environmental Planning Policy 71 – Coastal Protection SEPP 71 applies to the area declared as the NSW Coastal Zone under the Coastal Protection Act 1979. The NSW coastal zone can generally be described as a special transition area between land and water. Outside the greater metropolitan region the coastal zone extends from approximately one kilometre inland of any coastline, bay, estuary, lake or lagoon three nautical miles out to the edge of the State’s coastal waters (NSW Planning, 2016). The eastern boundary of the Evans Head Memorial Aerodrome is approximately 550 metres from the mean high water mark at Airforce beach. Hence SEPP 71 is deemed to apply. Clause 18 of this SEPP requires a masterplan for subdivisions located in a residential zone within sensitive coastal zones or, if not located in a sensitive coastal location zone that create 25 lots or more. The Minister may waive the need for a master plan to be adopted because of the nature of the development concerned, the adequacy of other planning controls that apply to the proposed development or for other such reasons as the Minister considers sufficient As the proposed development will create allotments in excess of this number, an application for ministerial approval or an application for an exemption is required. An application for exemption has been made with the Grafton office of NSW Planning. Evans Head Airpark – Statement of Environmental Effects Page 72 Regional Environmental Plans No Regional Environmental Planning Policies apply to the proposed development.

Richmond Valley Development Control Plan 2012 4.10.1 Part A – Residential development The proposed facility includes development of land to permit standalone and medium density residential dwellings. 4.10.2 Part B – Commercial development This section of the DCP does not apply as the proposed facility will not be undertaking commercial activities. 4.10.3 Part C – Industrial development The proposed facility includes land intended for industrial use. This will be in the form of hangars and sheds which will be used for aviation related activities. 4.10.4 Part D – Rural land uses This section of the DCP does not apply as the proposed facility does not include land for rural land uses. 4.10.5 Part E – Accommodation, Caravan Parks and Manufactured Home Estates This section of the DCP is in respect to Caravan Parks and Manufactured Home Estates. The masterplan for the facility makes allowance for hotel accommodation. Evans Head Airpark – Statement of Environmental Effects Page 85 4.10.6 Part F – Signage Minor signage will be erected to promote the site and to notify construction stages. 4.10.7 Part G – Subdivisions The site will be subdivided to allow effective management of the facility. A community lot will be created to contain the airfield. The industrial, museum and residential parts of the facility will be subdivided to allow the effective collection of annual contributions for the maintenance of the communal land. 4.10.8 Part H – Natural Resources The land is not flood affected. Bushfire prone land mapping indicates the land is classified as Bushfire Prone Land – Vegetation Category 1. The airfield is classified as Bushfire Prone Land – Vegetation Buffer. This is a trigger for integrated development, hence approval from the NSW Rural Fire Service under Planning for Bushfire Protection will be required. RVLEP 2012 Acid Sulfate Soil mapping classifies the site as Class 3. The map represents where acid sulfate soils may be present from and below a metre of the nature ground surface. An acid sulfate soil management plan is recommend when the nature of development poses an acid sulfate soil risk. This section of the DCP will apply as it is likely trenching works up to one (1) metre in depth will occur for sewer and/or water mains. The existing wetlands located in the northern section of the site will not be developed. 4.10.9 Part I – Other Considerations 4.10.9.1 Heritage conservation The site is subject to a heritage listing. A conservation management plan has been prepared and accepted by the NSW Heritage Council. A heritage impact assessment report has been prepared by Weir Phillips. 4.10.9.2 Building In, On, Over or Under a Road Access roads will be constructed to and on the Woodburn-Evans Head Road and Currajong Street. The former is a classified road under the Roads Act 1993 and concurrent consent will be required from the NSW Roads and Maritime Authority. Evans Head Airpark – Statement of Environmental Effects Page 86 4.10.9.3 Building Lines The development will comply with all relevant setbacks from public roads. It will also comply with the maximum 8.5 metre building height limitation. 4.10.9.4 Car Parking Sufficient car parking will be provided for each industrial hangar, the residential areas, and at the museum precinct. The rates will be as follows: Residential 2 per dwelling Medium density: 1 per dwelling + 1 per every 4 dwellings Industrial: 1 per 50 m2 of GFA The museum precinct will have a small number of carparks with overflow parking. Car parking will be addressed further when development applications are for the various building works. 4.10.9.5 Noise Impact The facility has the potential to have a noise impact on adjoining land users. A noise impact assessment has been undertaken to determine the likely impact on adjoining lands. 4.10.9.6 Social Impact The development will have an impact on the Evans Head and wider Richmond Valley Community. Additional aviation related activity will occur and there will be a corresponding increase in local economic activity. The facility’s dedicated industrial hangar areas will attract aviation related industry. There will be a corresponding increase in the skill base in the region. There is expected to be increase employment from the likely increase in demands for local services such as trades. The new museum precinct will be able to house additional aircraft and associated aviation related paraphernalia. There is likely to be an increase in tourism traffic to Evans Head to view the aircraft display and the role the airport played in training Australia’s bomber crews during World War II. The heritage-listed aerodrome will be maintained from levies collected from the members of the community scheme thereby contributing to the social wellbeing of the families of those men and women who participated in the training programmes. The DCP recommends a high level social impact assessment. Evans Head Airpark – Statement of Environmental Effects Page 87 Section 5.10 addresses socio-economic impact issues relating to the development. The assessment by Mitchel Hanlon Consulting is located in Appendix H. 4.10.9.7 Water Sensitive Urban Design Water Sensitive Urban Design integrates land use and water management (water supply, stormwater and wastewater) planning with the aim of minimising the impacts of urban development on the natural water cycle. Stormwater management is addressed in Section 5.11.5. 4.10.9.8 Crime Prevention through Environmental Design The site has been design with the principles of CPTED. The facility will have community ownership and be managed accordingly. The landscaped areas will be maintained as will the airpark infrastructure. Each residential precinct will be a naturally closed environment. Through traffic will not be possible. The public will generally be restricted to the museum and industrial precincts. 4.10.9.9 Land Use Conflict Land use conflict has been assessed for noise and the judicious location selection. The proposed aviation industrial hangars are located adjacent to the existing industrial precinct whilst the proposed museum has been located on the Woodburn-Evans Head Road. Evans Head Airpark – Statement of Environmental Effects Page 88 Environmental Impacts and Mitigation Measures Introduction A number of specialist environmental studies prepared for the site from which an assessment has been made of the proposed development. These studies comprised: Servicing Strategy (prepared by Mitchel Hanlon Consulting); Acid Sulfate Soils Assessment (prepared by Mitchel Hanlon Consulting); Traffic Impact Assessment (prepared by Seca Solutions); Noise Impact Assessment (prepared by Vipac Scientists and Engineers); Flora and Fauna Assessment (prepared by Peter Parker Environment Consultants Pty Ltd); Contaminated Land Assessment (prepared by MTNKR Consulting); Heritage Due Diligence Assessment (prepared by Weir Phillips Heritage); Bushfire Assessment (prepared by Mitchel Hanlon Consulting); and Socio-economic Consulting). Assessment Evans Head Airpark – Statement of Environmental Effects (prepared by Mitchel Hanlon Page 89 Acid Sulfate Soils 5.2.1 Introduction Acid sulfate soils are a major environmental issue for coastal areas, and can impact on the sustainability of local landscapes and waterways. Effective management is imperative to protect coastal water systems from the potential negative impacts caused by acid sulfate soils (ASS). Acid sulfate soils (ASS) are characterised by their high concentration of pyrite minerals (iron sulphide) and chemical by-products of pyrite oxidation. This oxidation process can occur naturally when pyrite is exposed to oxygen during times of prolonged drought or changes in tidal regimes. ASS can also be accelerated by human activities such as dredging, surface drainage changes and lowering of the local watertable. Acid sulphate soil disturbance can cause environmental impacts such as fish kills, increased mobility of acid, aluminium and iron within estuaries, fish disease, habitat degradation and human and animal health issues related to drinking of aluminium-rich groundwater. Potential acid sulfate soils (PASS) are characterised by: Contain iron sulfides or sulfidic material that has not been exposed to air and oxidised; Field pH in an undisturbed state is pH greater than 4; Presence of waterlogged soils; Presence of reduced sulphur odours; and Presence of shells. Actual acid sulfate soils (AASS) that have been disturbed and exposed to oxygen are characterised by: Soil pH of less than or equal to 4; Presence of shells; Jarosite deposits (pale yellow mottles); and Iron oxide deposits (orange to red secondary mottles). The potential activities to occur as part of the proposed development that may impact on PASS and AASS include: Water and sewer pipe installation; Site drainage works; Evans Head Airpark – Statement of Environmental Effects Page 90 Road construction and runway construction; and Building and structure foundation preparation and excavation. This section aims to outline the key results of the preliminary site assessment, discuss the potential impacts of the development on PASS and AASS, and proposed management strategies that may be implemented to ensure effective management of ASS onsite. 5.2.2 Preliminary Site Assessment 5.2.2.1 Desktop Study A desktop study of the site was undertaken to identify the potential for ASS to exist within the proposed development areas. The relevant documents identified to provide guidance for this assessment include: Richmond Valley Council Local Environmental Plan 2012; Richmond Valley Council Development Control Plan 2012 – Part H Natural Resources and Hazards (H3 Acid Sulphate Soils); Richmond Valley Council – Acid Sulphate Soils – Guidance for Construction Activities (June 2007); Ahern et. al.(1998) Acid Sulfate Soils Assessment Guidelines; Stone et. al.(1998) Acid Sulfate Soils Manual; and Stone and Hopkins (1998) Acid Sulfate Soils Planning Guidelines. The proposed subdivision development may require works to be undertaken below 1 metre of the natural ground surface. It is not envisaged that the local watertable will be affected by the proposed subdivision. However, in the interest of identifying all potential environmental issues of the site, a preliminary site assessment was undertaken. The Ahern et. al. (1998) ASS assessment guidelines were consulted for the appropriate preliminary assessment pathway as per the Richmond Valley LEP 2012. A desktop assessment based on Table 2.2 of the guidelines was undertaken. Similarly, the Richmond Valley Council – Acid Sulphate Soils – Guidance for Construction Activities (2007) document was consulted for council specific information. The proposed assessment will outline the key components required by the relevant documents including: Understanding the characteristics of ASS; Project planning in relation to ASS; Evans Head Airpark – Statement of Environmental Effects Page 91 Undertaking a preliminary ASS assessment for the site; and Identify suitable management strategies to be implemented during the construction and operation phases. 5.2.2.2 Existing Site Environment The ASS Assessment Guidelines identify a number of steps required to perform an ASS assessment of the proposed development site. A review of the acid sulfate soils planning maps for the Richmond Valley Council area was undertaken. The Richmond Valley Council LEP mapping indicates the proposed development site is identified as Class 3 acid sulfate soils. This classification requires development consent for: Works beyond 1 metre below the natural ground surface; and Works by which the watertable is likely to be lowered more than 1 metre below natural ground surface. At this planning stage of the project it is not clear whether works will extend more than 1 metre below the natural ground surface. Foundations for buildings, excavation of trenches for water and sewer piping, and road construction activities as part of the project may require the need for excavation greater than 1 metre below the natural ground surface. More detailed engineering information will be available during the construction certificate phase of the project. However, for the purposes of providing a comprehensive environmental assessment of the site, a preliminary ASS assessment was undertaken as per the ASS Assessment Guidelines (Ahern C R, Stone, Y, and Blunden B, 1998). An assessment of the geomorphic and site criteria to refine the broadscale mapping of the Richmond Valley Council LEP was undertaken. The geological criterion for potential ASS was reviewed. The site is located within a coastal wetland area and there are waterlogged areas on the site. The geological sediments are of recent geological age. OEH soil mapping undertaken on the site in 1993 indicate soil profiles approximately to 2 metres, and the lithology is described as aeolian sands (OEH, 1993). It was determined by the desktop assessment that the site was likely to disturb ASS as it is in a mapped Class 1-4 category as per the Richmond Valley LEP ASS mapping, however it is considered to have a lower probability of ASS being present based on the site geomorphology. The assessment option was to undertake step 3 (analyse soil and water indicators) and 4 (Chemical analysis to confirm ASS and action levels) as per the ASS Guidelines. The field sampling and analysis results are discussed further in Sections 5.2.2.3 and 5.2.2.4. Evans Head Airpark – Statement of Environmental Effects Page 92 5.2.2.3 Site Sampling Soil sampling was undertaken at the site on the 13th February 2014 by Ms Catherine Lockyer, Environmental Scientist at MHC. A visual inspection of the site was undertaken to confirm the geophysical characteristics in terms of predicting area of ASS. Site characteristics of wetland and poorly drained areas, and swamp-tolerant vegetation was observed on the site and indicate the potential for ASS to occur. There was no jarosite or iron mottling observed during the soil sampling. There was no shell material or scalded areas observed during the soil sampling. Six (6) test pits were sampled at 2 depths, 0-10 cm and 20-30 cm. A total of twelve (12) samples were taken from the site. The samples were submitted to East West EnviroAg laboratory in Tamworth for analysis. 5.2.2.4 Analysis Results and Discussion The soil samples were analysed for Total Oxidisable Sulfur (TOS) and Peroxide Oxidisable Combined Acidity and Sulfate (POCAS) laboratory methods as per the ASS Guideline recommendations. The results are summarised in Table 8. Appendix B provides the full analysis results. Table 9 outlines the action criteria from Table 4.4 of the ASS guidelines that triggers the requirement for an ASS Management Plan.

The soil pH ranges from 3.9 to 4.8 and indicates strongly acidic soils. Similarly, the oxidisable sulphur and titratable acidity results also indicate potential for ASS on the site. The analysis results trigger the requirement for ASS management on the site. Evans Head Airpark – Statement of Environmental Effects Page 94 5.2.3 Potential Impacts and Issues The preliminary desktop assessment and site soil sampling indicate there may be potential or actual ASS on the site. Preliminary soil sampling results are above the action criteria that trigger the need for an ASS Management Plan and ASS management on the site. The potential impacts that ASS could have on construction and operational activities includes: Type of engineering and landscaping works required; Design of roads, buildings, drainage systems, and material specifications; Maintenance programs for drains, water and sewage pipelines; Management of extracted ASS soil; and Affect biodiversity and aquatic systems. Potential impacts of ASS will be managed by implementing a number of management strategies throughout the construction and operation phases of the project. 5.2.4 Management Strategies Potential management strategies during construction include: Risk assessment of construction activities and potential for ASS disturbance; Prevent ASS oxidation by avoiding ASS hotspot areas, restricting watertable fluctuations, and removal or capping of ASS material once disturbed; Acid and pH control by using lime application to insitu and excavated soil; Containment and management of excavated ASS material onsite; Define a specific stockpile area for suspected ASS material; Dispose excavated ASS to landfill as a contaminated soil; Site layout adjustments to avoid construction activities on ASS hot spot areas; Drainage design adjustments to avoid construction activities on ASS hot spot areas; Source clean fill as construction material and not use onsite ASS as fill material; and Evans Head Airpark – Statement of Environmental Effects Page 95 Environmental monitoring of surface water, groundwater and soils during construction. 5.2.5 Monitoring Environmental monitoring is proposed during the construction phase of the project. A detailed monitoring plan will be prepared prior to construction works, and location of ASS areas will be taken into consideration. Environmental monitoring may include: Mapping of ASS hotspots; Effective communication with site construction employees about the risks of ASS disturbance and location of ASS hotspots; Daily inspections of the site; Visual inspections of excavated soil material for physical indications of ASS; Regular field testing and laboratory analysis of excavated soil material where ASS are suspected; and Regular laboratory analysis of surface waters and groundwater for changes in pH, electrical conductivity, chloride and sulphate concentrations which may indicate ASS impacts. All monitoring data will be compiled and reviewed regularly by the site manager. Soil monitoring data will be compared to the ASS Guidelines and recommended trigger concentrations for ASS indicator parameters. Water monitoring data will be compared to ANZECC Water Quality Guidelines (2000) and any indications of negative impacts on water quality will be further investigated. Where monitoring data indicates that potential contamination issues have occurred from ASS disturbance, works will be suspended until remedial actions are prepared and implemented. 5.2.6 Contingency Planning Contingency planning will be implemented onsite during the construction phase of the project. A number of measures will be implemented to ensure effective understanding of the potential ASS impacts on the environment. Procedures will be prepared for the management of ASS onsite and regular field/laboratory testing. Procedures for the site may include: Field testing of excavated soils for ASS potential; Laboratory testing of suspected ASS; Evans Head Airpark – Statement of Environmental Effects Page 96 Liming and treatment of ASS onsite (if this is an option); Handling of ASS and equipment requirements; ‘Toolbox’ information sessions on ASS management; Emergency measures for ASS management in adverse climatic conditions; WHS requirements for employees exposed to ASS; and Work method statements for onsite management of ASS. 5.2.7 Summary Acid sulfate soils can adversely affect coastal waterways if disturbed and not managed effectively. A preliminary desktop assessment was undertaken and indicated that ASS potentially occurs on the site. The geological and soil landform features suggest that ASS could exist and preliminary soil sampling confirmed that ASS may be present onsite. The extent of the ASS was not determined in the preliminary soil sampling. It is recommended that further soil analysis be undertaken to confirm the location of ASS hotspots. Broad management strategies and monitoring have been outlined, however more detailed management strategies and a site-specific monitoring plan will be prepared prior to construction works being undertaken. A detailed ASS Management Plan will also be prepared prior to construction to mitigate the potential impacts of ASS onsite. Evans Head Airpark – Statement of Environmental Effects Page 97 Climate Change Sea level rise is expected to increase the average depth in the estuary and extend tidal propagation up the estuary with potential changes in salinity regime. It is anticipated that sea level rise will naturally result in the landward recession of fringing estuarine wetland systems. The location of estuarine habitats such as mangrove forests and salt marsh are controlled principally by tidal range and salinity influence and will gradually respond to changes in increases in average water levels and salinity. There is a risk that natural upslope migration of these wetlands will be curtailed by anthropogenic constraints such as roads, levees, agriculture and urban development on the landward side (Department of Climate Change, 2009). Increased estuary water levels due to sea level rise will also affect riparian and other low-lying vegetation in the freshwater reaches of the estuary. While the location of estuarine vegetation communities in the Evans River has been mapped by DPI-Fisheries, it is not currently known to what extent barriers to upslope migration will affect the wetlands and vegetation communities. Due the existing high level of riparian vegetation cover along the Evans River and the planning protection afforded by environmental zoning along most of the river, it is likely that upslope migration of estuarine communities will proceed naturally for most of the estuarine extent. Exceptions may exist in the lower estuary where urban development could curtail migration of communities such as mangroves and small pockets of communities may be lost. The endangered Oxleyan Pygmy Perch (OPP) is found in the vicinity of Evans Head in low-lying freshwater habitats in wallum heathland. Significant efforts to identify and map habitat, restore and enhance habitats of the species have been undertaken in recent times. Due to the low-lying nature of OPP habitat, it is likely that at some point in the future, this habitat may be impacted by sea level rise. Evans Head Airpark – Statement of Environmental Effects Page 98 Traffic and Access All traffic will be able to enter and exit the site in a forward direction. All internal roads will meet Council requirements and allow for 2-way traffic movements. It is anticipated that the development will have a minimal impact on road safety. The current roads have good visibility and the traffic flows are expected to remain low. 5.4.1 Access New access to the site will be provided from Woodburn-Evans Head Road. This access will be in accordance with relevant council requirements. A second access will be provided from Currajong Street near Tuckeroo Crescent and will be developed as a roundabout. 5.4.2 Sight Distance Under the Austroads guidelines, a road operating under a posted speed limit of 80km/h requires a minimum sighting distance of at least 160 metres. The onsite sighting distance measured by Seca Solutions is in excess of 200 metres for both directions. Access from Currajong Street requires a sighting distance of at least 80 metres. The onsite distance measured is in excess of 200 metres in both directions. The sighting distances comfortably meet sighting requirements. 5.4.3 Parking Parking will be determined as part of the DA process. Residential parking will be at least one garage space and driveway space to allow for at least two vehicles. Evans Head Airpark – Statement of Environmental Effects Page 99 5.4.4 Traffic Generation Seca Solutions implemented the RTA Guide to Traffic Generating Developments to determine the worst case traffic movements. It should be noted that due to the nature of the development being targeted to retired people, traffic movements may be much less than predicted. The results can be seen in Table 10. It is anticipated that this added traffic will have minimal overall impact on the locality.

This was to determine the potential impacts of noise generated from aircraft movements from the Evans Head Aerodrome and to provide recommended minimum building requirements to minimise any potential impacts. 5.5.1 Modelling The Integrated Noise Model (INM) is a widely used prediction tool developed by the United States Federal Aviation Authority (FAA). Further, the model is approved for use in Australia by Air Services Australia, the governmentowned corporation responsible for endorsing ANEF contours at civilian airports. The INM was utilized in evaluating the noise levels of the development. Two flight movement scenarios were modelled: Current (2015-2016): Movements based on flight numbers at Evans Head Aerodrome; and Future (2019-2020): Movements based on the current scenario and extrapolated for increased use of the Aerodrome. The future scenario movements include all projected movements from the proposed development. The projected numbers were provided to Vipac. The projected numbers can be seen in Appendix D. 5.5.2 Results Both the current and future scenarios were modelled via the INM. The results for each are discussed further in the following sections. 5.5.2.1 Current Scenario (2015-2016) The ANEF contours as seen in Figure 18 show that the 20 ANEF line runs through the residential zone. Three dwellings and the proposed high-density residential area are within the 25 ANEF contour. AS 2021 recommends that residential uses within the 20-25 ANEF contour are conditional when internal noise levels are compliant. The Hotel sits below the 20 ANEF contour thus complies. Evans Head Airpark – Statement of Environmental Effects Page 101 Figure 18: ANEF Contours for the Residential Zone for 2015-2016 As seen in Figure 19, the ANEF 20 contour runs through the middle of the museum precinct. Five dwellings on the front row of the museum precinct will sit in the 20-25 ANEF contour.

The proposed high density area will sit in the 3525 ANEF contour. AS 2021 recommends that residential uses within the 2025 ANEF contour are conditional when internal noise levels are compliant. The Hotel sits below the 20 ANEF contour thus complies. Figure 20: ANEF Contours for the Residential Zone for 2019-2020 As seen in Figure, the ANEF 20 contour runs through the middle of the museum precinct.

Only events greater than 70 dB(A) are applicable. As seen in Figure 22 it can be seen that: No residential lots in the high density residential area are within the ANEF contour line; Eight residential lots in the museum precinct are within the ANEF contour lines; and No existing residences are within the ANEF contour line. Evans Head Airpark – Statement of Environmental Effects Page 105 Figure 22: Contour Line for 20 Events >70dB LASmax for 2019-2020 5.5.2.3 Future Scenario with Second Helipad Modelling was carried out with the addition of a second helipad which will be utilised by recreational helicopters. The existing helipad will remain but would only be utilised by emergency helicopters due to its proximity to the road. The ANEF contours as seen in Figure 23 show that the 20 ANEF line runs through the residential zone. The proposed high density area will sit in the 30 ANEF contour which is considered unacceptable per AS 2021. Evans Head Airpark – Statement of Environmental Effects Page 106 Figure 23: ANEF Contours for 2019-2020 with a Second Helipad The ANEF contours shown in Figure 24 indicate that two rows of residential dwellings sit below the 20 ANEF contour and one row of dwellings sit between the 20-25 ANEF contours. The museum site between the 20-25 ANEF contour which indicates compliance.

As seen in Figure 25 it can be seen that: No residential lots in the high density residential area are within the contour line; Eight residential lots in the museum precinct are within the contour lines; and No existing residences are within the contour line. Figure 25: Contour Line for 20 Events >70dB LASmax for 2019-2020 with two helipad Evans Head Airpark – Statement of Environmental Effects Page 109 5.5.3 Impacts on Existing Receptors Noise modelling was carried out in order to determine impacts on existing receptors. The LAeq contours for the current scenario can be seen in Figure 26. The LAeq contours for the future scenario with one helipad and two helipads can be seen in Figure 27 and Figure 28 respectively. The modelling indicates that increased aerodrome activity will extend the 60 dB(A) contour line by approximately 40 metres, the 55 dB(A) contour by 50 metres, and the 50 dB(A) contour by 80 metres. This shows: There is no increase in the number of residences in the 60-65 dB LAeq, day contour band; There is no increase in the number of residences in the 55-60 dB dB LAeq, day contour band; and The number of residences that will sit between the 50-55 dB LAeq, day contour band increases from five (5) to approximately seventeen (17). Evans Head Airpark – Statement of Environmental Effects Page 110 5.5.3.1 ANEF Contours A comparison of the ANEF current scenario and the future scenario both with one helipad and two helipads indicate that all receptors sit below the 20 ANEF contour. This suggests no negative impacts when compared to the current scenario. Figure 26: LAeq, day (2015-2016) (dB(A)) Evans Head Airpark – Statement of Environmental Effects Page 111 Figure 27: LAeq, day (2019-2020) (dB(A)) - One Helipad Figure 28: LAeq, day (2019-2020) (dB(A)) - Two Helipdads Evans Head Airpark – Statement of Environmental Effects Page 112 5.5.4 Summary There appears to be very little difference between the ANEF for 2015-2016 and 2019-2020. When comparing the future ANEF with one helipad against the ANEF with a second helipad, it is apparent that there is a significant reduction in the impacted dwellings. Six dwellings as well as the high density area are impacted with one helipad compared to just the high density area with two helipads. The modelling indicates that some dwellings may be classified as ‘unacceptable’ or ‘conditional’ per AS 2021. Where dwellings are classified as ‘conditional’, it is suggested that the building methods be utilised to minimise noise impacts. The recommendations made in the Vipac report are not final and will need to be assessed once each dwelling has been designed correctly. Where dwellings are classified as ‘unacceptable’ Clause 2.3.3 states that development can proceed in special cases. As the impacted dwellings will be inhabited by aviation enthusiasts, who will utilise the aerodrome for leisure, it is considered that this is a special case. Evans Head Airpark – Statement of Environmental Effects Page 113 Ecology 5.6.1 Statutory Considerations An assessment of the site was undertaken by Peter Parker Environmental Consultants (PPEC) in accordance with the following: NSW State Environmental Planning Policy 44 – Koala Habitat; NSW Threatened Species Conservation Act 1995; Environmental Planning and Assessment Act 1979; NSW Fisheries Management Act 1994; and Environmental Protection of the Environmental Conservation Act 1999 (Commonwealth). 5.6.1.1 SEPP 44 – Koala Habitat As the site triggers prescribed thresholds within SEPP 44 Koala Habitat, an assessment of potential koala habitat was undertaken. The aim of SEPP 44 is to encourage the proper conservation and management of areas of natural vegetation that provide habitat for koalas. This is to ensure a permanent freeliving population over their present range and to reverse the current trend of koala population decline. For potential koala habitat to occur, a minimum of 15% of the total number of trees in the upper or lower strata of the tree component need to be koala food species listed under Schedule 2 of the SEPP. Forest redgum was recorded at the site but was considerably less than the 15% requirement for potential koala habitat to occur. Thus potential koala habitat within the meaning of the SEPP does not occur at the site and therefore a koala plan of management is not required. Further, ecology field work failed to identify any evidence of koala activity on the site. 5.6.1.2 Environmental Planning and Assessment Act 1979 The Threatened Species Conservation Act 1995 (TSC Act) commenced on 1st January 1996. This Act, inter alia, amended s4, s110, s111 and s112 of the Environmental Planning and Assessment Act 1979 (EPA Act) with regard to the protection of plants and animals. S5A of the EPA Act (the “7-part test”) must be taken into account in deciding whether there is likely to be a significant effect on threatened species, populations or ecological communities, or their habitats. In regards to each, the relevant section and comment is provided. Evans Head Airpark – Statement of Environmental Effects Page 114 5A Significant effect on threatened species, populations or ecological communities, or their habitats: a) In the case of a threatened species, whether the action proposed is likely to have an adverse effect on the life cycle of the species such that a viable local population of the species is likely to be placed at risk of extinction. The following factors have been considered in assessing the likelihood that a viable local population of the species is likely to be placed at risk of extinction from this proposal: o the proposal’s likely impact upon the key habitat components essential to the species’ lifecycle; and o The size of the local population in comparison with that which is proposed to be removed/modified. No threatened plant species was recorded at the site. Accordingly, the proposal is unlikely to have an adverse effect on the life cycle of the species such that a viable local population of the species is likely to be placed at risk of extinction. Fauna: Wallum froglet: The development will not threaten a local population as the core habitat in banksia and paperbark woodlands and sedgelands within the Broadwater National Park will not be disturbed. Recommended mitigation measures include the treatment of stormwater in bio-retention swales. Wallum sedgefrog: No wallum sedgefrog habitat occurs within the area proposed for development and drainage from the site will not be directed into its habitat. Accordingly, the development will not threaten a local wallum sedgefrog population. Birds: Glossy black cockatoo: The glossy black cockatoo was recorded flying over the site by Parker in his 2001 survey. Hence, it will not be impacted as no feeding or nesting resources will be significantly removed or modified Bush hen: Impacts on this species are likely to be minimal due to the extensive areas of suitable habitat within the Broadwater National Park and Salty Lagoon to the north. Osprey: No suitable habitat is located at the site. Evans Head Airpark – Statement of Environmental Effects Page 115 Ground parrot: Play-back calls in 2014 did not detect this species and it is considered that the area where it was previously recorded is now marginal habitat as it has regenerated extensively after fires in 2000. Eastern grass owl: This species was recorded by Parker (2001) west of the site in the Broadwater National Park. The proposal is unlikely to impact on this species as no suitable habitat occurs at the site. Square-tailed kite: The proposal is unlikely to significantly impact on this species due to its extensive range and the availability of large tracts of suitable habit in the Evans Head region. Mammals: Hoary wattled bat: The habitat at the site is sub-optimal and the understorey vegetation is dense and senescent. Thus, the proposal is unlikely to result in any significant loss of foraging or roosting habitat. Yellow-bellied sheath-tailed bat: This species was recorded by Parker (2001) to the north of the site. The proposal is unlikely to result in any significant loss of foraging or roosting habitat. Large-footed myotis: This species was recorded near the site by Parker in 2001. However, no roosting sites or water bodies suitable for foraging occur at the site, thus this species will not be impacted by the proposal. Little bent-wing bat: The proposal will have little impact on this species as no roosting areas occur at the site. Common blossom bat: The proposal is unlikely to impact on this species roosting habitat as rainforest does not occur at the site. Eastern false pipistrelle: Suitable roosting locations were not recorded and it is unlike that roosting sites will be impacted. Grey-headed flying-fox: The proposal will require the clearing of potential sources of blossom which this species may utilise. However, the heath-leaf banksia and broadleaved paperbark woodlands and shrublands are common in the locality and the proposal is unlikely to pose a significant impact on this species. Evans Head Airpark – Statement of Environmental Effects Page 116 Common planigale: The common planigale is threatened by habitat clearing and burning and predation by feral animals, especially cats and foxes. The proposal is unlikely to impact on this species as it is not considered to occur at the site. Fish: Oxleyan pygmy perch: The major impacts on this species include the habitat modification, agricultural pesticides or fertilisers and introduced species such as the mosquito fish and possibly the cane toad. It is recommended that water quality control measures are incorporated into the site design to ensure water quality is not compromised. Provided that suitable measures are implemented it is unlikely that this species will be impacted by the proposal. The proposal is unlikely to have an adverse effect on the life cycle of any fauna species such that a viable local population of the species is likely to be placed at risk of extinction. b) In the case of an endangered population, whether the action proposed is likely to have an adverse effect on the life cycle of the species that constitutes the endangered population such that a viable local population of the species is likely to be placed at risk of extinction. No endangered populations listed under Part 2 of Schedule 1 of the TSC Act occur within the vicinity of the site. Thus, the action proposed is unlikely to have an adverse effect on the life cycle of the species that constitutes the endangered population such that a viable local population of the species is likely to be placed at risk of extinction. c) In the case of an endangered ecological community or critically endangered ecological community, whether the action proposed: i. Is likely to have an adverse effect on the extent of the ecological community such that its local occurrence is likely to be placed at risk of extinction, or ii. Is likely to substantially and adversely modify the composition of the ecological community such that its local occurrence is likely to be placed at risk of extinction, No endangered ecological community was recorded at or in the vicinity of the site. Thus, the proposal is unlikely “to have an adverse effect on the extent of the ecological community such that its local occurrence is likely to be placed at risk of extinction.” Nor will the proposal “substantially and adversely modify the composition of the ecological community such that its local occurrence is likely to be placed at risk of extinction.” Evans Head Airpark – Statement of Environmental Effects Page 117 d) In relation to the habitat of a threatened species, population or ecological community: i. the extent to which habitat is likely to be removed or modified as a result of the action proposed, and ii. whether an area of habitat is likely to become fragmented or isolated from other areas of habitat as a result of the proposed action, and iii. the importance of the habitat to be removed, modified, fragmented or isolated to the long-term survival of the species, population or ecological community in the locality, Habitat modification or removal Threatened species and threatened species habitat has been recorded within the study site and study area. However, this habitat is conserved within the Broadwater and Bundjalung National Parks. Habitat isolation or fragmentation The area of habitat proposed to be removed lies adjacent to the Broadwater-Evans Head Road. Its removal is not likely to fragment or isolate other areas of habitat. In conclusion, the habitat of a threatened species, population or ecological community will not be modified, fragmented or isolated any extent as a result of this proposal. The importance of habitat to be removed The proposal will not require the removal of any habitat of particular significance to threatened species or the removal of an EEC. Thus, the proposal will not affect the long-term survival of the species, population or ecological community in the locality. The long-term survival of the species, population or ecological community in the locality Section 5A(d)(iii) requires an assessment with respect to the importance of the habitat to be removed, modified, fragmented or isolated to the long-term survival of the species, population or ecological community in the locality. This site is located in proximity to habitats which are recognised for their high conservation value (e.g., the Broadwater National Park). The proposal will not require any habitat to be removed, modified or fragmented to the extent that it will significantly affect the long-term survival of the species, population or ecological community in the locality. Evans Head Airpark – Statement of Environmental Effects Page 118 e) Whether the action proposed is likely to have an adverse effect on critical habitat (either directly or indirectly), The site does not contain any area which has been identified and declared as critical habitat under Part 3 of the TSC Act. Therefore, critical habitat will not be affected by the proposal. f) Whether the action proposed is consistent with the objectives or actions of a recovery plan or threat abatement plan, Wallum sedgefrog and other Wallum-dependent frog species The National Recovery Plan for the Wallum sedgefrog and other Wallum-dependent frog species and the Oxleyan pygmy perch is relevant for the purpose of an assessment under s5A(f). The National Recovery Plan for the wallum sedgefrog and other wallum-dependent frog species identifies the relevant threats to these frog species. These are: habitat loss; habitat degradation; changes in hydrology; habitat eutrophication and pollution; habitat fragmentation as a result of land clearing; inappropriate fire regimes; predation by mosquito fish Gambusia holbrooki; and use of biocides in weed and mosquito control. The following is noted: Habitat loss: surveys with respect to the proposed development have identified the prime wallum froglet and wallum sedgefrog habitat and it does not occur within the development footprint. Habitat degradation: the proposed development is isolated from important Wallum sedgefrog and Wallum froglet; Changes in hydrology: it is recommended that runoff from the site passes through bio-retention filters and be directed away from sensitive areas. In order to compensate for the increase in hard surfaces and lower percolation rates water tanks should be used to collect stormwater for later discharge during dry weather Habitat eutrophication and pollution: accumulation of these toxicants in wetland areas could also have a negative impact on Wallum frog species in areas adjacent to developed areas. It is recommended that runoff from the site passes through bio-retention filters and be directed away from sensitive areas Habitat fragmentation as a result of land clearing: The proposed development will not result in the fragmentation of an isolated population of either the wallum froglet or wallum sedgefrog. Evans Head Airpark – Statement of Environmental Effects Page 119 Inappropriate fire regimes: This report identifies that asset protection zones can be suitably provided on the site. Predation by mosquito fish Gambusia holbrooki: Wallum frog species may therefore be highly susceptible to predation by this species. The mosquito fish was recorded in downstream receiving waters in the fish survey conducted for this proposal and is likely to be widespread in the locality. Biocides use for weed and mosquito control: there is no proposal to use pesticides to control mosquitoes at the site. Oxleyan pygmy perch An Oxleyan pygmy perch recovery plan has been prepared by the NSW Department of Primary Industry (2005). Specific objectives of recovery planning are as follows: Increase scientific knowledge and understanding about the distribution, habitat, life history, ecology and genetics of pygmy perch; Increase community awareness and support of pygmy perch recovery actions; Protect and restore essential habitats for pygmy perch; Minimise the impacts of introduced fish on pygmy perch; Reduce the illegal collection of pygmy perch by encouraging and involving aquarium enthusiasts to support recovery efforts; and Establish a program to monitor the status of pygmy perch and assess the effectiveness of recovery actions. With respect to the above, the recommended water quality management controls will “restore essential habitat”. None of the other specific recovery objectives are relevant with respect to this proposed development. g) Whether the action proposed constitutes or is part of a key threatening process or is likely to result in the operation of, or increase the impact of, a key threatening process. Threatened Species Conservation Act Potential threatening processes as defined under the TSC Act which may occur at the site include predation by foxes, introduced garden weeds, cane toad impacts, introduction of Phytophthora and the exotic rust fungi. However, the site will be landscaped using native species of local origin, and potential breeding sites for the cane toad will be minimised to the extent practicable and possible. Evans Head Airpark – Statement of Environmental Effects Page 120 This proposal includes the removal of woodland and shrubland. The extent of tree removal will destroy a sufficient proportion of one or more strata (layers) within a stand or stands of native vegetation so as to result in the loss, or long-term modification, of the structure, composition and ecological function of a stand or stands. The tree removal proposed is within the meaning of “clearing of native vegetation” as described above, this threatening process will increase as a result of this development proposal. Fisheries Management Act 1994 The proposal is unlikely to lead to any change or significant increase in any of the listed threatening processes, most of which are not relevant in the circumstances. 5.6.1.3 Environment Protection and Biodiversity Conservation Act 1979 The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) is a Commonwealth Act administered by the Department of the Environment. A search of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) protected matters database for the area was conducted on 1st December 2014. Parker has reported one (1) threatened ecological community, fifty-five (55) threatened species and forty-five (45) migratory species. The threatened ecological community is lowland subtropical rainforest which does not occur at the site. The fifty-five (55) threatened species listed includes shorebirds, marine fish, turtles, whales and sharks thus leaving fourteen (14) terrestrial species and one (1) fish, the Oxleyan pygmy perch, as the only fauna species which potentially may occur at or in the vicinity of the site. These are listed in Table 14 together with their likelihood of occurrence.

The spotted-tail quoll occurs in rainforest, open forest, woodland, coastal heath and inland riparian forest. Individual animals use hollow-bearing trees, fallen logs, small caves, rock outcrops and rocky-cliff faces as den sites, none of which occur at the site. Thus, the site contains marginal habitat for this species. The New Holland mouse occurs in open heathlands, woodlands and forests with a heathland understorey and vegetated sand dunes. It has been captured in the Broadwater area by this consultant in similar habitat to that which occur at the site. The leafless tongue orchid Cryptostylis hunteriana occurs in swampy heathland, the margins of coastal swamps and sedgelands, coastal forest, dry woodland, and lowland forest. It was not recorded at the site but suitable habitat occurs. The EPBC Act requires a person to not take an action that has, will have or is likely to have a significant impact on any of the matters of environmental significance without approval from the Commonwealth Minister for the Environment. An action is a project, a development, an undertaking, an activity or a series of activities, or an alteration of any of these things. Guidance is provided in the Commonwealth Department of the Environment’s significant impact guidelines as to whether the proposal is likely to have a significant environmental effect pursuant to the EPBC Act: A ‘significant impact’ is an impact which is important, notable, or of consequence, having regard to its context or intensity. Whether or not an action is likely to have a significant impact depends upon the sensitivity, value, and quality of the environment which is impacted, and upon the intensity, duration, magnitude and geographic extent of the impacts. Evans Head Airpark – Statement of Environmental Effects Page 123 To be ‘likely’, it is not necessary for a significant impact to have a greater than 50% chance of happening; it is sufficient if a significant impact on the environment is a real or not remote chance or possibility. If there is scientific uncertainty about the impacts of your action and potential impacts are serious or irreversible, the precautionary principle is applicable. Accordingly, a lack of scientific certainty about the potential impacts of an action will not itself justify a decision that the action is not likely to have a significant impact on the environment. To determine whether or not to refer an action to the Minister, the following criteria is required to be considered. Comments for each criteria with respect to the development and the site impact are provided: Are there any matters of national environmental significance located in the area of the proposed action (noting that ‘the area of the proposed action’ is broader than the immediate location where the action is undertaken; consider also whether there are any matters of national environmental significance adjacent to or Comment: The EPBC Act protected matters search tool was used to ascertain matters relevant to the site. Three (3) species, the spotted-tail quoll, the new Holland mouse and the leafless tongue orchid were considered to have potential habitat at the site. However, the spotted-tail quoll is unlikely to be impacted given its wide-ranging nature and the large expanse of suitable habitat available in the area. Similarly, an abundance of suitable habitat is available for the new Holland mouse in both the Broadwater National Park and nearby privately owned lands. The leafless tongue orchid was not recorded and no local records are known. It is unlikely that this species will be significantly affected by the proposal. Considering the proposed action at its broadest scope (that is, considering all stages and components of the action, and all related activities and infrastructure), is there potential for impacts, including indirect impacts, on matters of national environmental significance? Comment: Indirect impacts on the Oxleyan pygmy perch are considered to be negligible provided that the implementation of the recommended water quality controls is undertaken. Are there any proposed measures to avoid or reduce impacts on matters of national environmental significance (and if so, is the effectiveness of these measures certain enough to reduce the level of impact below the ‘significant impact’ threshold)? Evans Head Airpark – Statement of Environmental Effects Page 124 Comment: There are no proposed measures to avoid impacting on the vegetation but the vegetation associations are not listed as matters of national environmental significance. Are any impacts of the proposed action on matters of national environmental significance likely to be significant impacts (important, notable, or of consequence, having regard to their context or intensity)? Comment: The impacts of the proposal are not considered to be significant within the meaning of the definitions provided in the significant impact guidelines. 5.6.2 Recommendations The Oxleyan pygmy perch habitat south of the site is considered to be typical of wallum habitat; low salinity, low magnesium, low calcium hardness and a pH range of >3 to <7. The creek flows over siliceous sands and through aquatic vegetation and plant debris. The high organic acid content of this water body is derived from leachates from riparian vegetation. Parker recommends that the drainage waters from the site do not alter these characteristics. To this extent, it is recommended that engineering structures be designed and established and their efficacy modelled. It is recommended that road runoff is directed into pits with gross pollutant traps installed and a portion of the road runoff be treated by permeable pavers. With this system, roof water enters pits via roof water drainage lines, above the gross pollutant traps where possible. Runoff water then flows through vegetated open space (vegetated or bioretention swales) via surcharge pits for further treatment. Runoff water is then fed into the pygmy perch habitat rehabilitation area for final polishing. Evans Head Airpark – Statement of Environmental Effects Page 125 Contamination As previously mentioned the Old Council Depot site and the adjoining land to the south and south east are outside of the development boundary. As such, no development will occur on this land. The following sections detail the proposed course of action regarding the development and options regarding contamination. 5.7.1 Industrial/Commercial Hangar Area The proposed industrial/commercial hangar area is to be developed on the vacant industrial land. No further intrusive testing is proposed. Extensive investigations have already been carried out and appropriate Remedial Action Plans developed have identified the following areas requiring remedial action to bring the site within HILF Commercial/Industrial landuse criteria: TPH hotspot located on the western portion of the site; Heavy metal hotspot located in the northern portion of the site; PAH hotspots located in the western portion of the site; Asbestos fragments located on surface soils site wise; and PAH hotspot located in the north-west portion of the site. Due to changes in the NEPM in 2013, portions of the RAP may not be relevant. As such the recommendations of the existing RAP will be considered in light of the changes to the (NEPM 2013) and implemented as deemed necessary as part of the development of this precinct. This will include the preparation of an undated RAP Management Plan to Council advising of the proposed management approach. As the areas to be remediated are likely to be much less than 5 ha in total area, the remediation action is not anticipated to trigger Designated Development provisions. 5.7.2 Private Residential Airpark/High Density Area The Private Residential Airpark/High Density Area precinct proposed for the northern section of the Vacant Industrial Land has undergone contamination investigations associated with the Additional Supplemental Investigation of the Vacant Industrial Land and the associated Updated Remedial Action Plan, along with earlier intrusive investigations. As such no further intrusive investigations are proposed. Evans Head Airpark – Statement of Environmental Effects Page 126 The investigations identified elevated heavy metals associated with the previous land use which will require remedial action to minimise the potential risk of harm. The investigations also identified Benzo(a)pyrene at depths of between 0.10.2 m at TP-01 in exceedance of the NEPM (2013) criteria for high density residential use. This area will require further delineation to determine the spatial extent of the contamination; however, given the density of sampling within the immediate vicinity and the surficial extent of the contamination it is expected that volume of contamination will be minimal. The recommendations of the Updated RAP will be considered and implemented as deemed necessary as part of the development of this precinct. This will include the preparation of a Management Plan to Council advising of the proposed management approach. 5.7.3 Private Residential Airpark The Private Residential Airpark precinct that joins the eastern edge of the Vacant Industrial Land has undergone contamination investigations conducted as part of the Additional Supplemental Investigation of the Vacant Industrial Land and the associated Updated Remedial Action Plan along with earlier intrusive investigations. Of these intrusive investigations no samples returned results that exceeded residential land use criteria (HILA Standard residential with garden/accessible soil (NEPM, 2013)). As such no further intrusive investigations are proposed for this portion of the Private Residential Airpark precinct. The contamination investigations undertaken to date within the Private Residential Airpark precinct that overlays the Vacant Industrial Land confirmed no exceedances of residential land use criteria (HILA Standard residential with garden/accessible soil (NEPM, 2013)). As such, it is considered that the remainder of the Private Residential Airpark precinct presents a low risk of contamination being present that exceeds residential land use criteria HILA Standard residential with garden/accessible soil (NEPM, 2013). It is recommended that preliminary intrusive investigations be undertaken within the precinct to confirm the absence or otherwise of contamination occurring that exceeds residential land use criteria. The suggested sampling regime is located in Appendix F. Evans Head Airpark – Statement of Environmental Effects Page 127 5.7.4 Remediation The Updated Remedial Action Plan (AECOM, 2011) provides a range of remediation options to address contamination exceedances within the Vacant Industrial Land. As discussed above, the relevance of the RAP will be revisited after a review of the existing data for the Vacant Industrial Land against NEPM 2013 to determine the relevance of the recommendations. Due to the superficial nature and anticipated small volume of impacted material identified at the site the following general remediation options remediation options have been suggested by AECOM (2011) and still remain relevant if exceedances still exist when compared to NEPM 2013: PAH (soil): Excavate, stockpile and bio-remediate to re-use on site; Heavy metals (soils): Excavate, stockpile, classify on-site and dispose off-Site; TPH/BTEX (soils): Excavate, stockpile and bio-remediate to re-use on site; and Asbestos (soils): Manually hand pick - Emu Pick. The appropriateness of any particular option will vary depending on a range of local factors associated with the staging of the Airpark development and the prevailing site conditions. Evans Head Airpark – Statement of Environmental Effects Page 128 Heritage 5.8.1 Introduction Weir Phillips was engaged to prepare an assessment of the heritage impact. The assessment is located in refer Appendix C. A s60 application must be made to the NSW Heritage Council once approval has been obtained from Richmond Valley Council. 5.8.2 Background Evans Head Memorial Aerodrome has its origins as an emergency landing strip constructed in 1936. During World War II, the Aerodrome played a pivotal role in Australia’s contribution to the Empire Air Training Scheme (EATS). From August 1940 until December 1943, it operated as No. 1 Bombing and Gunnery School (No. 1 BAGS). No. 1 BAGS trained 5,500 RAAF personnel, over 1,000 of who were later killed in active service. In December 1943 No. 1 Air Observers School was relocated to Evans Head. Before the school was disbanded on 15 August, 1945 (Victory in the Pacific Day), over 630 personnel had been trained using Ryan, Tiger Moths, Wackett and Anson aircraft. The EATS programme came to an end in June 1944. From 1940 until 1944, the Aerodrome operated as a self-contained village that could accommodate up to 1,400 people. The Aerodrome returned to civilian use following World War II. The site is listed on the State Heritage Register (Item 01649), under the auspices of the NSW Heritage Act 1977, under the name ‘Evans Head Memorial Aerodrome.’ The site is also listed by Schedule 5 Part 1 of the Richmond Valley Local Environmental Plan 2012. The site is identified as ‘Evans Head Memorial Aerodrome (including runways, Bellman Hangar, timber huts and machine gun pit).’ 5.8.3 Impacts The proposed works are assessed under the controls provided by the Plan of Management for the site and by the Heritage Agreement between Richmond Valley Council and the Minister responsible for the administration of the Heritage Act 1977. The impacts are then summarised using the questions raised by the NSW Heritage publication Statements of Heritage Impact (2002 update). The following conclusions are drawn. Evans Head Airpark – Statement of Environmental Effects Page 129 Question 1: The following aspects of the proposal respect or enhance the heritage significance of the item or conservation area for the following reasons: Use as an aerodrome is the original and best use for the site. Provision is made for a museum to interpret and commemorate the site’s WWII history. The proposed lots are located outside of the areas of primary significance identified by the POM for the site. A sufficient curtilage is retained around surviving WW II fabric. There will be no impact on items in the vicinity of the site or the surrounding area. Question 2: The following aspects of the proposal could detrimentally impact on heritage significance. The reasons are explained as well as the measures to be taken to minimise impacts: Lengthening runway 18/36 will have no additional impact on the significance of the site. The creation of lots and the construction of buildings will alter the appearance of the site from the ground and from the air. Large groups of buildings are not an alien element to this site. During World War II, there were numerous huts, hangars etc on site. Building in the proposed areas, which is outside areas of primary significance, will not interrupt significant view corridors into, within or out of the site or important visual spatial relationships. 5.8.4 Plan of Management For the effective management of the heritage items onsite, a Plan of Management (PoM) was prepared by GHD Pty Ltd (2009). The PoM divides the site into five management zones. These zones are: Hangar conservation and aviation operation zone; Runway conservation and aviation operation zone; Aerodrome open space zone; Southern hangar/works depot zone; and Southern runway zone. Evans Head Airpark – Statement of Environmental Effects Page 130 The proposed residential lots will be located outside of the heritage zones. Further, the placement of buildings will not interfere with spatial relationships or views into or out of the site. A Section 60 Application will be required to NSW Heritage Council. 5.8.4.1 Hangar Conservation and Aviation Operation Zone The hangar conservation and aviation operation zone consists of the Bellman Hangar and the sites of five adjacent hangars together with the surrounding tarmac areas. The hangar sites may be used as sites for new buildings that have been designed to respect the ‘hangar aesthetic’ of the remaining hangar and World War II visual character of the complex. The tarmac areas surrounding the hangar will be retained, repaired or reconstructed where required. 5.8.4.2 Runway Conservation and Aviation Operation Zone The runway conservation and aviation operation zone consists of the four runways and immediately adjacent cleared grass strips and drainage systems. All of the runways are culturally significant and should be conserved as features in the aerodrome landscape. If runways are to be utilised for aviation operations, the strips are to be maintained to their current level. If they are no to be utilised, the strips will be managed as mown grass landscape elements, with no requirement to maintain the sealed surface to operational condition. 5.8.4.3 Aerodrome Open Space Zone The aerodrome open space zone consists of the existing open space between and adjacent to the runways. The landscape of this open grassland should be maintained to conserve the historic and cultural landscape values of place. Evans Head Airpark – Statement of Environmental Effects Page 131 5.8.4.4 Southern Hangar/Works Depot Zone The southern hangar/works depot zone consists of the sites of eleven former hangars, which have been extensively disturbed by post-World War II activities, to the point where very little evidence of their existence is discernible on the ground. Future development of the area should reflect the orientation, scale, and spatial arrangement of the World War II hangar complex without slavishly recreating hangar forms. 5.8.4.5 Southern Runway Zone The southern runway zone consists of the southern section of Runway 14/32 and associated taxiways, disturbed to varying degrees. The heritage significance in this zone relates to the role of the runways in the aerodrome landscape, but redevelopment for new uses could be allowed while still conserving that value. The alignment of runway 14/32 and the two taxiways should be retained in some recognisable form in the landscape. This may include the retention of open space, alignment of roads and adjacent building development, landscape treatment or some other approach that stresses the lineal nature of the runways and taxiways. 5.8.5 Recommendations It is proposed to retain and upgrade the facilities at the Aerodrome to create a residential airpark and associated community facilities. This proposal both continues the long use of the site for aviation, which is essential to its significance, and provides a viable source of funding to ensure its future viability. Provision of an aviation museum provides an opportunity to explore and interpret the significance of the site. The proposed lots are located outside of the heritage zones identified by the Plan of Management for the site. A full understanding of the orientation of, and relationships between, the runways is maintained. This is key to understanding the site from the ground and the air. Groups of buildings on this site are not a new phenomenon; large groups of buildings existed on this site during World War II. The proposed location of buildings will not interfere with any significant spatial relationships or view corridors into, within or out of the site. Evans Head Airpark – Statement of Environmental Effects Page 132 Bushfire 5.9.1 Introduction The site is identified by Richmond Valley Council as a bush fire prone area as per the NSW Rural Fire Service bushfire mapping for the region. Given the bushfire risk to the development a Bushfire Assessment has been prepared by Mitchel Hanlon Consulting in accordance with NSW Rural Fire Service’s (RFS) Planning for Bushfire Protection (PBP) 2006. The requirements and objectives of PBP 2006 have subsequently been applied to the proposed development. The bushfire assessment is contained with Appendix I of this document. A summary of the methodology utilised and the findings of the assessment has been provided below. 5.9.2 Bushfire Hazard Assessment Properties considered to be affected by possible bushfire impact are determined from the local Bushfire Prone Land Map as prepared by Council and / or the Rural Fire Service. All property development within affected areas is subject to the conditions detailed in the document ‘Planning for Bushfire Protection – 2006’ (PBP). Set back distances for the purpose of creating Asset Protection Zones (APZs) must be applied and any buildings must then conform to corresponding regulations detailed in Australian Standard 3959 – 2009 ‘Construction of Buildings in Bushfire Prone Areas’ (AS 3959 – 2009). Planning for Bushfire Protection – 2006, (PBP) provides for the protection of property and life (including fire-fighters and emergency service personnel) from bushfire impact. The thrust of the document is to ensure that developers of new properties or subdivisions include the constraints associated with the construction of buildings in bushfire prone areas within their proposed development sites. PBP is applicable to proposed development inside a determined Category 1 or 2 areas and also inside a buffer zone radius of 100 metres from a Category 1 bushfire area or 30 metres from a Category 2 bushfire area. Bushfire mapping for the site indicates that a majority of the site is identified as being bushfire prone. The mapping obtained delineates the western residential and museum precinct as Category 2 vegetation while the remainder of the bushfire vegetation is identified as Category 1. Evans Head Airpark – Statement of Environmental Effects Page 133 5.9.2.1 Predominant Vegetation Type An assessment of the predominant vegetation types were undertaken in accordance with NSW Rural Fire Service’s Planning for Bushfire Protection 2006. The vegetation type within the proposed development sites is predominantly characterised by ‘tall heath (scrub)’. There are large areas which are free of canopy or shrub vegetation and the groundcover is maintained (predominantly in areas surrounding the existing runways). Vegetation formations immediately surrounding (within 140 metres) the proposed development areas range from saline wetlands (a single, small patch) to tall heath and forests. Following the vegetation classification, fuel loads were determined for the identified community type, as detailed in the table below. The formation descriptions detailed within the NSW RFS Planning for Bushfire Protection have also been included. Table 15: Community Fuel Loads VEGETATION FORMATION DESCRIPTION FUEL LOAD Managed Lands Not defined as a vegetation formation that poses as a bushfire hazard N/A Tall Heath (Scrub) Heathlands greater than 2m tall. Includes Hawkesbury Sandstone Vegetation with scattered overstorey trees and predominantly healthy understorey and coastal heath. May include some mallee eucalypts in coastal locations. Dry Sclerophyll Forests (Shrubby subformation) Understorey dominated by shrubs including waratahs, banksias, spider flowers, pea flowers, gum trees, tea trees, native fuschias, boronias and wax flowers. Sparse groundcover comprised mainly of hard leaved sedges. Found on sandy infertile soils on exposed sites. 20/25 t/ha Saline Wetlands Distinguished by an abundance of salt. Halophytes abundant. Eg: mangrove swamps, salt marshes and seagrass meadows. Coast (tidal estuaries) and western plains (salt lakes). N/A 25 t/ha 5.9.2.2 Slope The proposed development area is located on the coastal flats (slightly sloping) of Evans Head. Field work was undertaken to determine the specific relative slope of the proposed development area with reference to surrounding areas. It was determined, using a clinometer, that the slope within 140 metres of the development area ranges from approximately 0 - <1 degrees. Table 2 below lists the directional slope adjacent to each development area. Evans Head Airpark – Statement of Environmental Effects Page 134 Table 16: Site Land Slopes DEVELOPMENT AREA (DA) Museum / Residential Precinct (Area 1) Residential Area / Hotel Area (Area 2) Northern Potential Future development Area (Area 3) Western Potential Development Area (Area 4) Nursing Home Area (Area 5) Commercial / Industrial Hanger Area (Area 6) ADJACENT SLOPE LAND (DEGREES) POSITION RELATIVE TO DEVELOPMEN T AREA POSITION RELATIVE TO DA SUBSEQUENT SLOPE FOR ASSESSMENT (DEGREES) North 0 Flat 0 East <1 Down Slope <1 South 0 Flat 0 West <1 Up Slope 0 North 0 Flat 0 East <1 Down Slope <1 South 0 Flat 0 West <1 Up Slope 0 North 0 Flat 0 East <1 Down Slope <1 South 0 Flat 0 West <1 Up Slope 0 North 0 Flat 0 East <1 Down Slope <1 South 0 Flat 0 West <1 Up Slope 0 North 0 Flat 0 East <1 Down Slope <1 South 0 Flat 0 West <1 Up Slope 0 North 0 Flat 0 East <1 Down Slope <1 South 0 Flat 0 West <1 Up Slope <1 The results of the slope assessment have been used to calculate the required asset protection zones in Section 5.9.2.4 of this report. Evans Head Airpark – Statement of Environmental Effects Page 135 5.9.2.3 Bushfire Risk The site has been identified by Richmond Valley Council as a bushfire prone area as per the NSW Rural Fire Service bushfire mapping for the region. The following factors have been taken into consideration for this risk assessment: (a) Lot 3 in DP 1217074 has been identified as a site with a potential bushfire risk (Category 1 – greater than 1 hectare of vegetation type 1 or 2). The site is located within an area shown to be bushfire prone on the Richmond Valley LGA Bushfire Mapping published by NSW RFS; and (b) The proposed development area contains both category 1 and category 2 vegetation. The vegetated area mentioned is required to be assessed to determine the overall fire hazard. 5.9.2.4 APZ A significant area of the proposed development has been identified as having a potential risk of bush fire. The development area proposed, adjacent to each of the risk areas, requires an Asset Protection Zone (APZ). Asset Protection Zones for residential subdivisions are determined from Table A2.4 of PBP 2006 or radiant heat modelling not exposing the closest part of a dwelling to greater than 29 kW/m2. As the proposed development does not contain a habitable component there are no minimum required Asset Protection Zones. The APZ is required to ensure compliance with the deemed-to-satisfy arrangements under the Building Code of Australia (i.e. the provisions for Level 3 building construction of AS 3959 and Planning for Bushfire Protection 2006). An Asset Protection Zone constitutes an Inner Protection Area (IPA) immediately surrounding the building and an optional Outer Protection Area (OPA) which adjoins the IPA and the bush land. For forest and woodland vegetation, the IPA manages the heat intensities at the building surface and incorporates the surrounding defendable space whilst the OPA reduces the potential length of flames by slowing the rate of spread, filtering embers and suppressing the crown fire. Evans Head Airpark – Statement of Environmental Effects Page 136 The APZs for the development precincts 1-4 have been determined based upon the following values: FDI Rating (80); Slope; and Vegetation Type. Table 17 (p139) demonstrates the APZ calculations for each side of the development sites. APZs have not been calculated for Development Area 5 as the potential future nursing home is not a part of the proposed EHAP development. This area was included in the vegetation assessment for the purpose of completeness of information and providing greater environmental context. Special Fire Protection Purposes In NSW, a hotel or other tourist accommodation is identified as a type of Special Fire Protection Purpose (SFPP) development. SFPP developments are required to be assessed as ‘Integrated Development’ under S.91 of the Environmental Planning & Assessment Act 1979 and will require a Bushfire Safety Authority from the NSW Rural Fire Service (as per S.100B of the Rural Fires Act 1997). Special Fire Protection Purpose requirements apply to developments where the occupants may be more vulnerable to bushfire attack for reasons including age, physical limitations, mental limitations, unawareness of the local area etc. As the proposed museum and hotel are identified as potentially being Special Fire Protection Purposes (SFPPs) and the evacuation challenges associated with these types of development, the Asset Protection Zone requirements are based on keeping radiant heat levels at buildings below 10kW/m2. It is noted, however, that Planning for Bushfire Protection states that ‘...for some SFPPs, such as tourist accommodation… are occupied by able-bodied persons and that evacuation plans or refuge are appropriate alternative options”. Additionally, PBP states that where the proposed building is in excess of 100 metres from bushfire prone vegetation, radiant heat levels are not required to comply with the 10kW/m2. It is noted that the proposed Museum building will not be located within 100 metres of any bushfire prone vegetation. Subsequently the required APZ will be determined by applying the 29kW/m2 APZ specifications. As a result of the Museum Precinct of the development being identified as a SFPP, an emergency evacuation plan has been prepared for the site (Included as Appendix B in the attached Bushfire Assessment). Evans Head Airpark – Statement of Environmental Effects Page 137 It should be noted that while the external potential nursing home site has been included in this assessment for the purpose of completeness of information, an emergency evacuation plan for the proposed facility has not been compiled. The nursing home site does not comprise a part of the EHAP proposal and subsequently, should it be developed in the future by another proponent, should be subject to a separate bushfire assessment and preparation of an associated emergency evacuation plan. A preliminary concept plan has not yet been designed for the proposed hotel area (which is also a SFPP). APZs have been calculated based on keeping radiant heat levels at less than 29kW/m2.

Given the nature of the proposed development it is recommended that the entire APZ be managed as an IPA (Inner Protection Area). This area will require: Fuel at ground level to be kept at a minimum; Trees and shrubs do not overhang buildings; The placement of vegetation does not provide a path for the transfer of fire; The placement of vegetation does not allow for direct ignition, or ignition by radiant heat, of a building; and Stored combustible material is not kept within the IPA. The APZ is discussed further in relation to building requirements in Section 10 of the attached Bushfire Assessment. It should be noted that the APZ on the southern side of the Hotel/residential precinct is only required to be extended the stated amount into areas of forest. PBP does not state required APZs for saline wetlands; subsequently the APZ for a freshwater wetland has been adopted. Sensitive areas of saline wetlands are deemed to only require an APZ of 10 metres which is accommodated by the proposed road. 5.9.2.5 Property Access – Fire Services & Evacuation Access to the subdivision for fire fighting vehicles is provided through newly constructed roads via Woodburn-Evans Head Road, Memorial Airport Drive and Currajong Street. The internal access roads within the development will be two-wheel drive, all weather roads. Fire Trails To increase access and defense mobility for fire trucks, it is recommended that fire trails be constructed along the northern boundary of the museum/residential precinct and along the northern boundary of the residential/hotel precinct. In this instance, fire trails are required to be used instead of perimeter roads as a result of the multiple crossings of aviation taxiways (a gravel fire trail will not inhibit the movement of aircrafts). Evans Head Airpark – Statement of Environmental Effects Page 141 The proposed fire trails and access points are deemed to comply with the access requirements Planning for Bushfire Protection 2006. As such, access for Fire Service’s and staff evacuation is considered satisfactory. 5.9.3 Building and Construction Considerations Australian Standard AS 3959-2009 Construction of buildings in bushfireprone areas contains six Bushfire Attack Levels (BAL) each with a prescribed suite of design and construction specifications aimed at preventing ignition during the passing of a bushfire front. The BALs are introduced below: BAL-LOW: The threat does not warrant application of construction standards. Developments with BAL-LOW are generally not within bushfire prone land (greater than 100 metres from bushland); BAL-12.5: Addresses background radiant heat at lower levels and ember attack; BAL-19: Addresses mid-range radiant heat and ember attack; BAL-29: Addresses high range radiant heat and ember attack; BAL-40: Addresses extreme range of radiant heat, potential flame contact and ember attack; and BAL-FZ: Addresses construction within the flame zone. The BALs under have been mapped in Figure 30, Figure 31and Figure 32. N.B. If the stated APZ maintained to the minimum standard as stated in PBP, these BALs are deemed adequate. However, if these APZs are not maintained then a higher level of BAL may be required. Evans Head Airpark – Statement of Environmental Effects Page 142 5.9.4 Recommendations A bushfire assessment has been undertaken to determine the presence and degree of bushfire threat applicable to the proposed development. The result of the assessment is to create a series of recommendations which will seek to create a safe environment for the future users of the proposed development. If the minimum recommended building requirements, Asset Protection Zone and Asset Protection Zone maintenance is carried out as required, then the development has the ability to manage and survive the potential for bushfire attack present within the area. Asset Protection Zones (APZs) as depicted in Figure 29 be adopted for the proposed development to ensure protection from Bushfire; Building envelopes, as depicted in Figure 29, Figure 31and Figure 32 be enforced through a section 88b instrument community title scheme. Minimum AS 3959-2009 building and construction requirements, be enforced through a section 88b instrument community title scheme; Asset Protection Zones should be regularly maintained to ensure the APZ is effective in providing an adequate protection area between assets and any potential bush fire events. APZ maintenance should include regular mowing of any grass. The requirements for Asset Protection Zone maintenance are set out in Planning for Bushfire Protection, 2006; Any future landscaping within the development should take into consideration the type of shade trees used to ensure the genus of tree planted does not contribute to any fuel load build-ups within the future landscaped areas of each allotment. Any future landscaping should comply with the principles within Appendix 5 of PBP (‘Bushfire Provisions – Landscaping and Property Maintenance’); Emergency fire trails be constructed as per Figure 33 to ensure emergency exits routes for residents, and ease of access for fire fighters in the event of a bushfire. Emergency fire trails will be required to be constructed to a standard which allows a fully loaded fire tuck to be able to navigate them. Construction Should be in accordance with ‘Access (3) – Fire Trails’ in the NSW Rural Fire Service Planning for Bushfire Protection; and All internal roads associated with the development are constructed in accordance with Table 4.1 of Chapter 4 of the NSW Rural Fire Service Planning for Bushfire Protection (minimum width requirements).

The report identifies potential social and economic issues arising as a result of the proposed development, and recommends mitigation measures to address these issues.. 5.10.1 Existing Conditions and Expected Impacts The identified potential economic and social impacts, both positive and negative, arising from the development generally includes: Demographic changes to the area through employment of permanent and casual staff; Positive economic impacts of new employment and flow on effects to the surrounding area; Social amenity impacts on neighbouring properties from potential impacts on amenity: Increased traffic flow; Increased aircraft movements; Increased demand on utility services; and Increase in tourist visitor numbers. Economic and social impact from the following elements of the proposed airpark, residences, industrial precinct and museum: o Preservation of the heritage and unique history of the aerodrome; o Support, enhancement and promotion of the region and of existing events; o Bring sustainable investment opportunities to the region o Raising the profile of the Richmond Valley for future investment; o Support of region as place to invest and grow; o Employment and training opportunities; o Increasing the business diversity in the region by expansion into the aviation and hospitality industries; Evans Head Airpark – Statement of Environmental Effects Page 149 o Provide an improvement to business confidence; and o Provide an increase in the accessibility of Evans Head and visitors. 5.10.2 Population The coastal township of Evans Head is part of the Richmond Valley in the Northern Rivers region of NSW. The Richmond Valley LGA spreads from the coastline at Evans Head to the rural hub of Casino, a total area of approximately 3,050 sq. km. The region has a population of over 22,600 (Census, 2011) with the coastal township of Evans Head comprising around 2,600 people. The population is continuing to grow with the population of Richmond Valley increasing at an annual rate of 0.5% over the past five years which is the same as the average annual growth rate for the Northern Rivers (0.5%) but lower than NSW (1.4%) over the same period. The Richmond Valley LGA can be further divided into the ‘Casino’ region, and the ‘Balance’ of the LGA which includes the township of Evans Head. For the ‘Balance’ the growth rate is significantly less, with an annual rate for the period 2006-2011 of only 0.1% (refer Table 18). Over the period to 2036, the population of Richmond Valley is expected to increase by an average annual rate of 0.4% whereas the forecast for the Northern Rivers is 1.0% and New South Wales is 0.9%. Future forecasts for continuing population growth in the Richmond Valley require an estimated 9,900 new homes to be built by 2031, particularly for Casino, which will be the main growth centre. Given current projections it is unlikely that the population of Evans Head will substantially alter in the foreseeable future. Evans Head Airpark – Statement of Environmental Effects Page 150 Table 18: Population POPULATION REGION 2011 LEVEL ANNUAL % CHANGE AVERAGE ANNUAL % CHANGE (200611) Richmond Valley 22,697 0.2 0.5 Richmond Valley – Casino 11,430 1.0 0.9 Richmond Valley – Balance 11,267 -0.5 0.1 Northern Rivers 287,809 0.2 0.5 NSW 7,302,174 1.1 1.4 5.10.3 Regional Economy The Richmond Valley has historically been dependent on primary industries and food manufacturing enterprises supported by a number of agricultural businesses. There is also an active retail and tourism sector with growth in the creative industries, building and construction sectors. Traditionally, Evans Head has relied primarily on the Fishing Industry. However, by 2006 the professional fishing fleet operating from Evans Head had decreased to around 18 vessels from over 80 vessels based in the harbour in the 1960s. This industry has diminished considerably. The local economy lacks diversify scoring low across a number of standards. There has been some diversity within the local economy with the development of residential subdivisions, a response to the “Sea Change” effect, an industrial estate and a commercial precinct predominately providing retail and property services. The result is greater year round activity. Evans Head remains a popular holiday destination with tourism and support services. It has a number of attractions, natural assets and State Heritage Listed sites as well as annual events. Tourism remains a focus of Richmond Valley Council and is viewed as a key mechanism to attract visitors and revenue to the region. Events such as Primex, Beef Week and the Evans Head Fishing Classic and Fly-in attract out-of-region income. Evans Head Airpark – Statement of Environmental Effects Page 151 5.10.4 Socio-Economic Performance Richmond Valley Council is actively looking for opportunities “for developing a robust and resilient economy that can cater for future population growth.” (Richmond Valley Council website). This is a clear priority given that the Richmond Valley LGA has also been identified as a region with diminished social and economic performance. It has a low socio-economic base and is among one of the most disadvantaged LGAs in NSW. 5.10.4.1 Key Socio-Economic Indexes Socio-Economic Indexes for Areas (SEIFA) is a product developed by the Australian Bureau of Statistics (ABS) that ranks areas in Australia according to relative socio-economic advantage and disadvantage. Table 19: Socio-Economic Indicators INDICATOR RICHMOND VALLEY SCORE STATERANK (OUT OF 153) NATIONAL RANK (OUT OF 564) Socio-Economic Advantage & Disadvantage 887.63 7 56 Socio-Economic Disadvantage 899.55 8 62 Economic Resources 939.69 18 97 Education and Occupation 877.24 1 27 The low rankings indicate relative disadvantage for the Richmond Valley LGA across all key indexes. Regionally, statistical information from the 2011 Census shows that the Richmond Valley Council local government area rates well below the other NSW councils in the northern region (refer Table 20). Table 20: 2011 ABS population figures for regional LGAs Decile 1 is the most disadvantaged compared to other Deciles. Percentage 1 is the most disadvantaged compared to other percentiles. Evans Head Airpark – Statement of Environmental Effects Page 152 5.10.4.2 Economic Profile The region has low economic diversity. The Index of Economic Diversity measures economic or industrial diversity within a region. When the index value is close to one, the industrial profile of a region more closely mirrors that that the national economy and is considered more diverse. Using this comparative benchmark, the Richmond Valley LGA is significantly less diverse than all seven northern NSW councils and NSW more generally. Table 21: Economic Diversity Index INDICATOR ECONOMIC DIVERSITY INDEX Richmond Valley LGA 0.408 Northern Rivers 0.804 NSW 0.980 Richmond Valley Economic Brief, February 2013 The Gross Regional Product (GRP) of the Richmond Valley LGA for 2011/12 was an estimated $823.6 million, with real annual growth of 7.3%. This was significantly higher than the average annual growth for NSW (2.4%). In terms of business numbers, Agriculture, Forestry and Fishing is the largest industry in the Richmond Valley, accounting for 37.3% of all businesses in the region. At only 4.3% manufacturing is one of the smallest industries in actual business numbers yet is the region’s most significant producer of income at 21.6% of GRP. Health Care and Social Assistance contributes 7.5% of GRP. The manufacturing sector is the largest employer in the Richmond Valley in 2011, with 19.2% (1,184 persons) of the total workforce. The total working population (2011) was 6,152 persons, a slight decrease of 115 persons from the 2006 census. 5.10.4.3 Employment The unemployment rate in the Richmond Tweed area was 5.2% in the April 2016 quarter (Dept of Employment. 2016). The unemployment rate remained only marginally higher than the Northern Rivers (5.6%), NSW (5.2%) and Australia (5.2%). May 2016 quarterly unemployment figures from the Department of Employment indicates the Richmond – Tweed region had an unemployed rate of 5.2% and a youth unemployed rate of 14.3%. The state average was 5.3% and 11.9% respectively. Evans Head Airpark – Statement of Environmental Effects Page 153 5.10.4.4 Summary Richmond Valley Council’s low socio-economic base coupled with fundamental weaknesses in the diversity of the economy, presents a number of challenges for the region if it is to improve prosperity, achieve sustainable economic growth and enhance the liveability of the region. A competitive LGA is more likely to deliver sustainable economic growth resulting in vibrant social communities. However this depends upon current economic performance and what demographic advantages one LGA has compared to others. 5.10.5 Economic Impacts At present the aerodrome is supported by voluntary organisations and the local council with very little income being derived for its own upkeep. As a consequence it is a somewhat neglected and high maintenance asset. The conversion of the aerodrome to a medium-sized airpark will not only conserve the heritage and environmental values of the site, but bring economic opportunities for the local community whilst simultaneously reducing the cost burden on Council. The economic values of the project are primarily achieved through the delivery of a range of service businesses attracted to the project due to its importance as an aviation hub and the scope of its tourism potential. These will generate economic and diverse employment opportunities for the local community. In addition to the direct opportunities, it is anticipated there will be indirect flow-on effects of benefit to the community. The ‘multiplier effect’ of both direct and indirect businesses contributing to goods and services within the local region will create subsequent employment opportunities 5.10.5.1 Aviation Related Business Opportunities The proposal aims to establish significant aviation businesses by the provision of: Commercial aviation hangar sites and Light Industrial allotments with priority for aviation related businesses. To-date there are four (4) businesses interested in establishing themselves at the airpark: Curry Kenny Aviation Group; Aircraft Maintenance Specialists; Matt Hall Racing/Inverted Down Under; and Thrillion Air. Evans Head Airpark – Statement of Environmental Effects Page 154 There are indications that an aviation cluster will develop. The proponent has received enquiries from a number of parties interested in establishing a presence once development is complete. Thus it is expected there will be an immediate boost to the local economy from these and other businesses with a corresponding positive effect. 5.10.5.2 Employment The proposed enterprises would stimulate employment via the provision of specific opportunities in the aviation field. This would be an additional and diverse offering to the range of jobs and occupations currently available in the local area. It would be expected that some of these opportunities would be available for the youth of the Evans Head community. To-date, the potential number of positions available can be determined as follows: Table 22: Employment ENTERPRISE INITIAL FURTHER POTENTIAL POTENTIAL IDENTIFIEDTODATE +42 if relocate Caloundra Curry Kenny Aviation Group 9 + 4 if setup small remote relocation of helicopter and fixed wing charters 55 13 Additional support services in local community e.g. welding, electrical etc 13 plus Matt Hall Racing 3 Plus support services 3 Thrillion Air 3 Aircraft Maintenance Specialists Expressions of Interest Total 3 Up to 33 staff 28 79 33 107 This is an anticipated initial employment opportunity of up to 30 jobs with an identified potential of over 100. Evans Head Airpark – Statement of Environmental Effects Page 155 5.10.5.3 Local Economy In addition to the direct employment and economic activity generated by the new businesses, many will rely on local suppliers and skills to provide goods and service critical to their specific product delivery. This will have broad positive effects on commercial businesses currently in Evans Head providing a multiplier effect for stimulating the rest of the local economy. 5.10.5.4 Tourism and Hospitality Related Business Opportunities Tourism features as one of the key focus areas for Richmond Valley Council to stimulate the region and help provide a comparative advantage over other areas. The Airpark proposal will stimulate tourism via the establishment of a number of attractive and compelling tourist and visitor opportunities. This includes: The restoration of the Bellman Hanger as the first home for an Aviation /Historic Museum; A boutique hotel/ convention centre with 60-90 rooms; A future museum precinct; and The Aeroclub, eatery and community recreation facilities. The redevelopment would also support and facilitate events and functions such as the Great Eastern Fly-in and “the low level activity linked to the museum and resident historic exhibits. Tourism trade would thus be increased and the local economy boosted via new business investment and the resultant impact on employment, visitor numbers, and enhancement of the competitive advantage of the region. Evans Head Airpark – Statement of Environmental Effects Page 156 5.10.5.5 Employment There are a number of employment opportunities that would arise from the proposed tourism businesses. Table 23: Employment BUSINESS INITIAL FURTHER POTENTIAL POTENTIAL IDENTIFIEDTODATE Hotel Convention Centre 9 Plus ancillary contractors 22 Museum 1 1 Aeroclub – Café/Restaurant 1 2 Total 23 2 23 That is an initial employment opportunity of over 20 positions. 5.10.5.6 Local Economy With the expectation of a substantial boost to tourism in area there would be an anticipated flow-on to all ancillary business supplying tourism services in the region. This would provide security and opportunities for the local supply chain with a resultant multiplier effect. In addition, by supporting the use and maintenance of the existing aerodrome infrastructure, it would enable more fly-in activity in addition to the commercial and residential usage of the airport, and enhance the opportunity for more visitors to the area. 5.10.5.7 Construction Phase Additional contribution and stimulus during the construction phase is estimated to have a value of $157,535,997. Estimates for the construction of the civil component of the development and the estimated build costs are detailed in Table 24.

Unit costs from Rawlinsons Australian Construction Handbook with country loading Evans Head Airpark – Statement of Environmental Effects Page 158 5.10.5.8 Council Revenue and Expenditure Council will realise the direct economic benefit from the elimination of the cost burden of maintaining the aerodrome and its associated liabilities. With the re-development Council would also realise the additional income from the increase to the number of active ratepayers once occupancy is achieved. 5.10.6 Social Impacts Social indicators have determined that the Evans Head area is one of the most disadvantaged economically and socially in NSW. Some of the perceived issues are: Opportunities for youth particularly regarding employment; Education and training; Educational advancement; and Accommodation for a growing population. And a sustainable and robust local economy that provides for its residents. There is arguably a very strong link between the vitality of a local economy and the social standards realised in any location, with indicators such as employment providing the platform for social advancement. 5.10.6.1 Employment Without adequate employment, the maintenance of any community’s social fabric is at risk. One of the main drivers for impacts on community fundamentals is employment. Any opportunity to provide more and better jobs will help promote and sustain economic and social development. The proposal would help bolster employment during the construction and operational phase. Construction work will be available for both the civil and building phases. Post construction employment opportunities will be available with the hotel, aviation industry, and aerodrome maintenance and operation. Increased employment opportunities will have consequent positive social impact. 5.10.6.2 Education and Training The new businesses attracted to the Airpark development will not only generate employment opportunities but will require ongoing training and skills development. Evans Head Airpark – Statement of Environmental Effects Page 159 Skill levels, the type of jobs and roles, gaining of qualifications and potential career paths are other important employment factors crucial to the overall social and financial well-being of a regional centre. Specifically in the Evans Head area there is an identified need to recruit and retain skilled employees and the challenge of retaining youth. The new businesses attracted to the Airpark development will not only generate employment opportunities but will require on-going training and valuable skills development. With the introduction of the skilled employment opportunities in aviation and hospitality, there is a desire to also promote subjects locally with the high school and not only improve prospects for employment at the aerodrome but also within industry more generally. 5.10.6.3 Housing The Richmond Valley LGA has been identified for major population growth with the requirement for substantial new homes to be built to meet the demand. Niche housing will be required at the airpark. The estimated build can be considered is surplus to the trend estimates within Council commissioned economic studies. 5.10.6.4 Infrastructure/Isolation The site would continue as a working aerodrome. Upgrade of the facilities would increase usage from aviators resident to the aerodrome and the Evans Head community whether residential or with commercial interests. Some usage will occur as a result of tourism and commercial visitors to the Aerodrome. This could help reduce the relative isolation of the township via the improvement of infrastructure for aviation users. The upgraded facilities would also provide availability at no cost to emergency services such as airborne bush firefighting, air ambulance and air evacuation. 5.10.6.5 Community Facilities The community would also benefit from enhanced amenity via the provision of new and improved facilities. Evans Head Airpark – Statement of Environmental Effects Page 160 Museum “The proposal to establish a sizeable museum at the aerodrome has drawn interest from various private collectors interested in placing their rare machines in the building for visitors to appreciate. Over time the museum will become a key tourist feature for the town attracting increasing numbers of visitors which will no doubt have positive benefits for the local community”. Open Space The proposed environmental open space as part of the development will create a natural area for both local residents and tourists. Preserving the natural space in the north-west of the site is paramount and emphasis has been made to retain vegetation habitat. Environmental education will be implemented by using interpretive signage throughout the conservation area. Providing cycle ways and pathways throughout the complex, connecting residential areas to the beach and township, will enhance community access 5.10.6.6 Promotion and Pride A new exciting and innovative airpark development should bolster community pride and facilitate promotion of the area. The development provides an opportunity for Council, community groups and the general public to explicitly and actively market the Airpark and other local attractions to a wide range of potential visitors, future investors and new residents. Both business and household confidence should be boosted as a result and further encourage the spending and investment that helps drive economic growth. 5.10.6.7 Net Community Benefit In order for the project to proceed it must demonstrate a net benefit for the community as a result of the development. In addition to the many benefits detailed above the proposal can be reviewed against outcomes of the SWOT analysis conducted by Richmond Valley Council and published in the Economic Development Strategy 2010-2015. This enables a reconciliation of the deliverables of the project against perceived key inherent prospects and limitations of the region Those most relevant items are tabled in Table 25.

Richmond Valley Council is actively looking for opportunities to develop a resilient economy that can cater for future population growth and provide employment opportunities for local people. Moreover, RVC is seeking higher utilisation of the existing asset in the heritage listed Evans Head Memorial Aerodrome and to minimise maintenance costs. The project is well aligned with the priorities outlined in the Richmond Valley Council’s strategic plans to facilitate a robust economy and provide for community priorities. The proposal development will assist with diversification of the local and regional economy which is presently heavily dependent on the primary industries of agriculture, forestry and fishing and on manufacturing. There will be a lift in the aviation and hospitality related sectors. Tourism activity will also increase upon the completion of the museum complex. It is estimated that there is an initial employment opportunity of up to 30 jobs with an identified future potential of over 100 within the aviation-related industries. A further 23 jobs are predicted within the tourism and hospitality related businesses derived from the project. From a socio-economic perspective the project delivers against the triple line of sustainable economic development, environmental performance and social vitality. The proposal offers an opportunity to capitalise on inherent advantages and strengths of Evans Head locality to facilitate this. Regional areas that host an airport and aviation services generate an increase in economic development leading to expansion of businesses and community facilities. Evans Head Airpark – Statement of Environmental Effects Page 164 Servicing Strategy The proposed development will have a significant demand on utility services and on stormwater. The following sections quantify the demand for services and address the identified impacts. The full servicing strategy is located in Appendix I. 5.11.1 Water Supply Capacity The water supply to the site will be supplied from the extension of the existing network. Presently, the industrial and residential areas to the south and east are serviced by via 150 mm diameter main and a 100 mm internal pipe. Section D11.09.7 of the Northern Rivers Local Government, Development and Design Manual, requires a minimum of 100 mm diameter main and 150 mm diameter pipe for commercial, industrial and high-rise building areas. Though the fire-fighting requirements are met by the existing system, it is proposed to install 100 mm and 150 mm diameter pipe in the subdivision. Maximum unassisted pressure at the highest elevation in the development site is approximately 534 kPa. The following pressure requirements have been met for a fire brigade pumping appliance: 250 kPa for Attack fire hydrant, unassisted; and 150 kPa for Feed fire hydrant, unassisted The 10.5 L/s flow rate for the 100mm diameter water main is marginally above the 10 L/s hydrant flow rate criteria 5.11.1.1 Internal Water Supply The internal water supply will have the following characteristics: The eastern residential, industrial and medium density precinct areas will be serviced via the extension of the existing 150 mm diameter water supply main located within Memorial Airport Drive. The new 150 mm main will be installed in the footpath of the proposed new road running from Memorial Airport Drive to Currajong Street. The new 150 mm main will connect to the existing 100 mm diameter water supply main in Currajong Street; A new 100 mm main will be installed throughout the residential area (including the proposed future hotel) and connect back on to the proposed 150 mm main. This will ensure hydraulic connectivity thereby reducing the incidence of air pockets in the line; Evans Head Airpark – Statement of Environmental Effects Page 165 The western museum precinct will be serviced via a new 150 mm connection to the 200 mm water main located on the northern side of Woodburn-Evan Heads Road. The new 150 mm main will be installed in the footpath of the proposed roads and extended throughout the residential / museum area and reconnect to the existing 200 mm diameter water supply main in Woodburn-Evan Heads Road. Negotiations will be held with Rous Water following the issue of development consent; The exact location and depth of the water mains will need to be confirmed prior to formalising the proposed connection points above; The main will provide water supply to each of the residential lots via water standard water service connections. Each connection will be metered and have a non-return valve to prevent backflow contamination; External fire hydrants will be installed in the water main at 70 metre intervals. Hydrants will also be installed at high and low points in the line; Stop valves will be installed in the water main to permit maintenance; and Services to be in accordance with Council requirements. Typically 20mm diameter services are required. It is should be noted that the above mentioned provisions are concept only and are subject to significant change as a result of the design phase. 5.11.2 Electricity A review of the available ‘Dial-Before-You-Dig’ plans indicates that, at present, there is extensive electricity infrastructure exists within the local area. It is our understanding that at present electricity power supply is supplied to the site and nearby industrial lands via overhead reticulation. However, future electrical servicing will be provided via underground reticulation. A suitably qualified consultant will be engaged to undertake the necessary electrical design upon the issue of Development Consent. Subsequent confirmation that suitable electrical services are available for the development will be obtained from Essential Energy following the construction of the infrastructure and forwarded to Council. Evans Head Airpark – Statement of Environmental Effects Page 166 5.11.3 Telecommunications A review of the available ‘Dial-Before-You-Dig’ plans indicates that, at present, there is extensive telecommunication infrastructure exists within the local area. All telecommunication services will be provided via the extension of the existing telecommunication infrastructure located within the vicinity of the site. A suitably qualified consultant will be engaged to undertake the necessary telecommunication design upon the issue of Development Consent. Subsequent confirmation that a suitable telecommunications supply is available for each lot will be obtained from Telstra/NBN following the construction of the infrastructure and forwarded to Council. 5.11.4 Natural Gas A review of the available ‘Dial-Before-You-Dig’ plans indicates that, at present, there is no existing natural gas connections located within the development site. As such, no allowance has been made to supply the development with reticulated gas. 5.11.5 Stormwater Drainage Pipe flow within the industrial site will be determined for the 5-year and 10year (where necessary) ARIs. It is intended to develop a network of pits and drainage lines to carry all developed runoff from the proposed development during a 5-year (residential areas) and 10-year (commercial/industrial/hotel and museum areas) ARI rainfall event. A series of overland flow paths have will also be designed to cater for stormwater surcharging for the piped network in the event of a 1 in 100 year storm event. It is intended that all internal roads and taxi ways will function as overland channels directing flows to existing discharge points. The capacity of these discharge points will be confirmed during the design phase. Should these points be found to be at capacity or ‘under-sized’ suitable augmentations or upgrades will be undertaken. The principal discharge point for the eastern portion of the site has been identified as the existing channel located on the eastern side of BroadwaterEvans Head Road / Flame Street whilst the secondary discharge point is the existing culvert beneath the intersection Evans Head Road / Flame Street and Currajong Street. The principal discharge point for the western portion of the site has been identified as the existing culvert located beneath Woodburn-Evans Head Road. Evans Head Airpark – Statement of Environmental Effects Page 167 It is should be noted that the above mentioned provisions are concept only and are subject to significant change as a result of the design phase. 5.11.5.1 Stormwater Quality Stormwater from the proposed allotments will be partially captured by on-site rainwater tanks. Dwellings harvest rainwater and potentially re-use that rainwater for toilet flushing and gardens and in some cases laundry. In addition to the obvious resource efficiency outcome the rainwater tanks also mitigate the effect of urbanisation on the flow regime of the waterways. By reducing the peak flows the aquatic ecosystems within the waterways are better conserved. Due to the flat nature of the site, runoff discharged from the lots, access roads and taxiways will flow via overland flow paths to the existing channels and waterways. These flow-paths will consist of road kerb and gutters, swale drains and table drains. Some site regrading will be required to ensure flow efficacy. The regrading will consist of cut-and-fill to achieve maximum falls of 0.3 to 0.5%. As a result, changes in elevation are expected to be minimal. Water quality will be controlled via gross-pollutant traps and bio-retention units located within the drains and at the point of discharge to the existing waterways. The bio-retention units will be designed to work in conjunction with a traditional kerb and guttering approach preferred by residents. The bioretention units will be positioned on the border of the riparian reserve treating stormwater before it enters the waterway. The riparian areas will be maintained and managed as functioning waterways in an urban context. The intent is for the waterways to be to be a feature of the subdivision. A riparian buffer will be maintained to ensure the sustainability of the aquatic ecosystems. Walkways will be incorporated into the design to allow public access. Erosion and sediment control will be installed and maintained in accordance with NRLG’s requirements and Landcom’s Managing Urban Stormwater, Soils and Construction (‘Blue Book’). Evans Head Airpark – Statement of Environmental Effects Page 168 5.11.6 Sewer Sewer for the site will connect to the existing rising (pressure) sewer main which traverses the site. The projected Equivalent Tenements (ET’s) for the proposed development in relation to sewerage has been calculated in accordance with the ‘AUSSPEC#1 Development and Design Manual’. Section D12.06 states that initial design may assume that one Equivalent Tenement (ET), which equates to a standard single dwelling unit, is equal to 3.2 equivalent persons (EP), i.e. 1 ET = 3.2 EP. Based upon the relevant design loading criteria, the number of ETs for the development are detailed in Table 28.

This pump station discharges to the existing 300mm rising main which traverses the site; Should the servicing of these areas not be possible (due to minimum grade restrictions etc), the areas will be serviced via a combination of gravity and pressure sewer systems; It is understood that due to recent development within the area the existing pressurised sewer main that traverses the site (north to south) is expected to be at capacity; As such, it is proposed to construct a new suitably sized pump station located towards the center of the site. A new suitably sized rising main will also be constructed to convey sewage to the sewage treatment plant to the north of the site; It is proposed to relocate the length of rising main fronting proposed lots 14 – 28; Lots 14 – 28 (industrial hanger lots) will be serviced via new gravity sewer mains, these mains will transfer sewage to a grinder pump station (or similar) which will feed to the proposed pump station; and All lots within Precinct 2 will be serviced via new gravity sewer mains, these mains will transfer sewage to the new pump station which will feed to the proposed the rising main. Evans Head Airpark – Statement of Environmental Effects Page 171 It should be noted that the above mentioned provisions are concept only and are subject to significant change as a result of the design phase. Erosion and Sedimentation Erosion control will be implemented at this site during construction activities to minimise soil erosion and protect surface water quality. Sedimentation of surface flows will be minimised by ensuring stockpiles are located within the construction zone and sediment fencing is installed around the downslope area of the stockpile. Rock line energy dissipaters will be installed and allow sediment to settle out of surface water prior to moving offsite. Detailed erosion and sediment controls measures will be detailed in the construction drawings at the Construction Certificate stage. Landscaping The site will be significantly landscaped to enhance the amenity of the site. Landscaping will need to be cognisant of aviation criteria. A landscaping plan will be submitted with the construction drawings at the Construction Certificate stage. Evans Head Airpark – Statement of Environmental Effects Page 172 Justification of the Proposal It is necessary to consider the reasons for carrying out of this proposed development and having regard to the biophysical, economic, and social considerations of the proposal, and the principles of ecologically sustainable development (ESD). Biophysical Considerations The various significant components of the biological and physical environment have been well documented and discussed in the previous sections of this statement, and the associated appendices. Social and Economic Considerations From an economic perspective, the proposed development will benefit the Evans Head area through stimulation of the local economy and by providing job opportunity for local people. The development also represents the opportunity for cost reductions in the operation and maintenance cost of the local aerodrome. Local construction business will benefit during the construction phase and utilise local labour and materials. The local economy will benefit from increased consumer spending by local businesses supplying labour and/or goods and services during construction. Once completed, the airpark, hotel, aviation enterprises and museum will benefit the local economy by providing directed sustainable employment and local business spending on goods. The development will help alleviate the low diversity in the Richmond Valley LGA economy. Evans Head Airpark – Statement of Environmental Effects Page 173 Principles of Ecologically Sustainable Development The principles of Ecologically Sustainable Development (ESD) are found in Schedule 2 of the Environmental Planning and Assessment Regulation 2000 (EPA Regulation 2000) and in s6 of the Protection of the Environment Administration Act 1991 (PEA Act), They are defined as follows: The “precautionary principle”, namely that if there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation; “Inter-generational equity”, namely that the present generation should ensure that the health, diversity, and productivity of the environment is maintained or enhanced for the benefit of future generations; “Conservation of biological diversity and ecological integrity”; that conservation of biological diversity and ecological integrity should be a fundamental consideration, and “Improved valuation, pricing and incentive mechanisms”, namely that environmental factors should be included in the valuation of assets and services. Evans Head Airpark is committed to the use of environmentally friendly practices in the development of the airpark. Furthermore, in considering this application, it needs to be remembered that ESD requires the effective integration of economic and environmental considerations in the decisionmaking process [s.6(2) Protection of the Environment Administration Act, 1991]. This Statement of Environmental Effects has outlined the current environmental qualities of the site and mitigation measures to minimise environmental impact from the proposed development. Evans Head Airpark – Statement of Environmental Effects Page 174 7.3.1 The Precautionary Principle The EPA Regulation 2000 defines the precautionary principle as: …if there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation. Further, the EPA Reg states that, in applying the precautionary principle, decisions should be guided by: i. Careful evaluation to, wherever practicable, avoid serious or irreversible damage to the environment; ii. An assessment of the risk-weighted consequences of various options In the preparation of the proposed development of the airpark, the Precautionary Principle has been adhered to, as evidenced by: Pre–Development Application consultations and meetings with Richmond Valley Council; Discussions by the local museum and various adjoining neighbours; Careful evaluation of the perceived threats of environmental damage, as well as comprehensive planning, evaluation, and development of the implications of the proposal; Consideration of the aerodrome’s considerable heritage value; Assessment of the impact of noise on the local community and The objective and comprehensive environmental assessment of the proposed development. This application is the result of a thorough assessment and evaluation of the environmental impacts which may result as a consequence of this proposal. Issues such as: noise, traffic, flora and fauna, site contamination and coastal sensitivity have been examined and reported in conformance with the requirements of this principle. Based on implementation of the proposed mitigation measures, the proposed development will not contribute to serious or irreversible damage to the local environment. Evans Head Airpark – Statement of Environmental Effects Page 175 7.3.2 Intergenerational Equity The EPA Regulation 2000 defines Intergenerational Equity as …the present generation ensuring that the health, diversity and productivity of the environment are maintained or enhanced for the benefit of future generations. The proposed development is in accordance with the principles of intergenerational equity on the following basis: It will result in a significant and sustained stimulus to the local and regional economies; It will improve the economic viability of many of the region’s existing grain producing land holdings; The burden upon the utility for infrastructure upgrades and electricity supply will diminish; and The carbon footprint of the facility will be significantly reduced. 7.3.3 Conservation of Biodiversity and Ecological Integrity The EPA Regulation 2000 states: …conservation of biological diversity and ecological integrity should be a fundamental consideration. Biological diversity is defined by the Threatened Species Conservation Act 1995 (TSC Act) as: …the diversity of life and is made up of the following 3 components: (a) genetic diversity - the variety of genes (or units of heredity) in any population, (b) species diversity - the variety of species, (c) ecosystem diversity - the variety of communities of ecosystems The proposed development will preserve the variety of biodiversity and ecological integrity on the site by: The introduction and implementation of erosion and sediment control measures; Maintenance of the existing waterways and dams on the site for aquatic species; Sustainable wastewater irrigation with minimal impact on soil structure and nutrient loads; and Evans Head Airpark – Statement of Environmental Effects Page 176 Maintenance of native vegetation via landscape screening. This has great potential to maintain native flora and fauna in the area once established. 7.3.4 Improved Valuation, Pricing and Incentive Mechanisms The principle of Improved Valuation, Pricing and Incentive Mechanisms deems that environmental factors should be included in the valuation of assets and services. The EPA Regulation 2000 identifies the following methods to achieve this: (i) Polluter pays: those who generate pollution and waste should bear the cost of containment, avoidance or abatement; (ii) The users of goods and services should pay prices based on the full life cycle of costs of providing goods and services, including the use of natural resources and assets and the ultimate disposal of any waste; and (iii) Environmental goals, having been established, should be pursued in the most cost effective way, by establishing incentive structures, including market mechanisms, that enable those best placed to maximise benefits or minimise costs to develop their own solutions and responses to environmental problem The triple bottom line analysis includes costs associated with using or impacting upon environmental resources. Such costs should be factored into development proposals so that the value of the end-product and/or service in seen in the broader context of the natural environment. In terms of the proposed development, Evans Head Airpark will bear the full costs associated with: The maintenance of the heritage items at the aerodrome. This will be achieved via the use of a sinking fund and levies raised from the community title scheme. A life-cycle plan will be developed to determine the value of the levy. The maintenance of all non-heritage items at the aerodrome and its compliance with all aviation safety requirements. The avoidance, abatement, containment and management of any incident that results in or has the potential to result in environmental pollution during the construction and operation of the development; The appropriate management of all waste streams generated by the development except those considered to be more appropriately collected and managed by Richmond Valley Council; The upgrade and/or extension of infrastructure to service the proposed development; and Evans Head Airpark – Statement of Environmental Effects Page 177 Fulfilling and complying with the conditions of consent applied by Richmond Valley Council. The proposed airpark development will result in an improvement in the maintenance and environmental performance of the aerodrome. Analysis of Alternatives The applicant has considered the alternatives to investing considerable finances into the proposed development. These include: a) The do nothing option. The developer Evans Head Airpark is solely committed to the development of the Evans Head Aerodrome. If development consent cannot be achieved, it is unlikely the company will seek a similar site either locally or further afield. Moreover, the opportunity to take over the cost of maintaining the aerodrome, enhancing its infrastructure, providing local job and business opportunities would be lost. b) Discontinue operations. This is unlikely as Council has a commitment to maintaining the aerodrome’s operational capability for local operators and for the Great Eastern Fly In. Moreover, the site is heritage listed and as such requires ongoing care and maintenance in accordance with the site’s Heritage Management Plan. 7.4.1 Consideration of Alternative Sites Due to the nature of the proposed development, there is no similar sites available in the region. Councils are generally examining means to enhance the economic opportunities for their local communities through the development of Council owned aerodromes. Examples include: Temora Shire Council: development of their aerodrome into an airpark and heritage museum. Like Evans Head, Temora provided aircrew training during the Second World War. Glen Innes Shire Council: development of the Glen Innes Aerodrome into a 600 student flying college. Development consent has been granted and funding is being sought to finance the development. Tumut Shire Council: development of 70 aviation industrial lots. Armidale Dumaresq Council: development of aviation industrial lots. Evans Head Airpark – Statement of Environmental Effects Page 178 Potential sites would need to satisfy a number of criteria: satisfy ANEF noise criteria, have access to utility services, be located in an attractive setting, provide suitable amenities and access to local commercial centre. Because of the time required to locate and acquire a suitable site that complies with the criteria plus the cost of development, this option is not considered viable 7.4.2 Consequences of the Development Not Proceeding If the development were not to proceed, it is likely Richmond Valley Council will be required to continue funding the maintenance of the aerodrome. Council may elect to reissue expressions of interest for the use of the aerodrome. It is possible a commercial or not-for-profit organisation may come forward and be willing to invest funds. It is almost equally possible no entity will emerge who is willing to undertake any activity at the aerodrome. It is more likely Council will undertake or facilitate development of the area in piecemeal. The area adjacent to the industrial estate would likely be developed to allow expansion of the industrial precinct. The existing Bellman hangar will remain the base for the museum. The Great Evans Head Fly In will continue and there may be organic growth in the number of visitors to the event. It is unlikely to be a significant increase in tourism revenue unless additional aviation or related events are scheduled. The foreseeable future will see Richmond Valley Council needed to allocate both monetary and human resources to the aerodrome. Evans Head Airpark – Statement of Environmental Effects Page 179 Conclusion As this Statement of Environmental Effects outlines, the proposed development of an integrated residential, industrial and commercial aviation hub is well suited to Evans Head Aerodrome. The Evans Head Aerodrome is an active aerodrome and is a state listed Heritage item. This listing is courtesy of its important role as a training facility in World War II. Recently, the last remaining onsite Bellman Hangar has been refurbished by the developer. As the development is being carried out by aviation enthusiasts, it will respect the aesthetic of the aerodrome and honour the role it played in World War II with the development of a museum. The site, currently owned by Richmond Valley Council, is maintained by volunteers and generates very little income for its upkeep. This development would see an increase in revenue so that the site can be maintained and enjoyed by the community. It also offers the Evans Head region an opportunity to gain a unique development that will lead to increased tourism. Several specialist investigations were carried out to ensure minimal impact to the site and surrounding areas. It was determined that no significant impacts are likely to occur as a result of the development. Further, through this development, it is likely that several associated benefits will occur such as increased employment opportunities, strengthening of the aviation industry and improved physical management of the site. During the construction process it is intended to use local businesses where possible. Once construction has been completed jobs will be created onsite in a range of industries. This will improve economic viability for the local economy through increases in employment opportunity, tourism opportunity and diversification of the local region. The installation and management of sediment and erosion control devices will aid in protecting local waterways around the site. Additionally, the planting and maintenance of native vegetation will assist with establishing and maintaining flora and fauna around the site. Based on implementation of proposed mitigation measures, the development will not contribute to serious or irreversible damage to the local environment.

Asbestos ID was analysed by Approved Identifier: Asbestos ID was authorised by Approved Signatory: INS: Insufficient sample for this test NA: Test not required <: Less than Not applicable for this job Not applicable for this job PQL: Practical Quantitation Limit RPD: Relative Percent Difference >: Greater than NT: Not tested NA: Test not required LCS: Laboratory Control Sample Quality Control Definitions Blank: This is the component of the analytical signal which is not derived from the sample but from reagents, glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples. Duplicate : This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selected should be one where the analyte concentration is easily measurable. Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist. LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortified with analytes representative of the analyte class. It is simply a check sample. Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds which are similar to the analyte of interest, however are not expected to be found in real samples. Laboratory Acceptance Criteria Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries for the batch were within the laboratory acceptance criteria. Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sample extraction. Spikes for Physical and Aggregate Tests are not applicable. For VOCs in water samples, three vials are required for duplicate or spike analysis. Duplicates: <5xPQL - any RPD is acceptable; >5xPQL - 0-50% RPD is acceptable. Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140% for organics and 10-140% for SVOC and speciated phenols is acceptable. In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, the sample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols. When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis has proceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon as practicable.

Introduction Background Seca Solution Pty Ltd has been commissioned by Mitchel Hanlon Consulting on behalf of Evans Head Airpark Pty Ltd to prepare a traffic and parking report for the proposed redevelopment of the Evans Head airport, Evans Head NSW. The plans are for the partial re-development of the subject site allowing for a residential sub-division as well as hotel development, with additional land potential for future development at a later stage. This assessment has allowed for the initial residential development and hotel development only. The subject site is located on the northern fringe of Evans Head and will gain access direct to Evans Head Road as well as Currajong Street. The site is bounded by a mix of residential and light industrial users to the south whilst to the north and west the site is bounded by open land. As part of the project, Seca Solution has collected current traffic data on Evans Head Road during both the morning and afternoon peak periods to determine current traffic flows and observe current road operations. Planning Context In preparing this document, the following guides and publications were used: • • • • RTA Guide to Traffic Generating Developments, Version 2.2 Dated October 2002. Note the RMS have advised that this document can continue to be used. RMS Technical Direction Guide to Traffic Generating Developments, Updated Traffic Surveys and Trip Rates August 2013; Richmond Valley Council Development Control Plan Australian / New Zealand Standard – Parking Facilities Part 1 : off-street car parking (AS2890.1:2004); The location of the site is shown below in Figure 1. 2 Subject site Figure 1 – Site Location 3 2. Traffic Impact Assessment Summary The following assessment has been completed in accordance with the requirements of the RMS’s Guide to Traffic Generating Developments and Austroads Guidelines. Note that whilst this publication has been withdrawn by the RMS, their advice is that it can be used until the revised guide is published. Item 2.1.1 Site Location and Access 2.2.1 Road Hierarchy 2.2.2 Roadworks 2.2.3 Traffic Management Works 2.2.4 Pedestrian and Cycling Facilities Comment The site is located on the northern fringe of Evans Head and has road frontage to Evans Head Road and Currajong Street. There are two separate access points proposed, with one off each of these roads. Evans Head Road runs along the southern boundary of the site and provides the road connection between Evans Head and Woodburn to the west. It provides a single lane of travel in both directions in the locality of the subject site and provides the road access to connect the locality with the Pacific Highway at Woodburn. It operates under the posted speed limit of 50 km/h in Evans Head which then increase to 80 km/h outside of the urban area. There is a dedicated off road footway / cycleway running along the northern side of this road and parking is available along the unsealed verges to both sides of the road. It connects with the Pacific Highway to the west via a give way controlled intersection which allows for all turning movements and provides a sheltered right turn lane on the Pacific Highway. The Pacific Highway forms part of the National Highway system and provides an important road link along the east coast of Australia. It provides a single lane of travel through Woodburn with additional lanes at the key intersections to maintain capacity. It carries local traffic as well as a high volume of through traffic traveling interstate. Currajong Street runs along the southern boundary of the subject site and connects with Evans Head Road at a 3-way roundabout controlled intersection. This roundabout forms the gateway to Evans Head and re-enforces the urban speed limit change to 50 km/h. Currajong Street provides a single lane of travel in both directions with roll over kerbs to both sides. There are no footpaths provided along its length, reflective of the low traffic and pedestrian demands in this area. It operates under the posted speed limit of 50 km/h. Currajong Street connects with a number of local roads allowing for connection to the centre of Evans Head as well as Beech Street for access to the sea front. Richmond Valley Council is the road authority for any new works on or adjacent to the roads within Evans Head and Evans Head Road. None noted in the general vicinity of the site. The RMS are continuing to upgrade the Pacific Highway with the aim to ultimately provide a dual carriageway alignment to maximise safety and capacity and as part of this upgrade, the road diverts away from the major residential centres. The upgrade will allow for a bypass of Woodburn but the RMS currently have no plans for the upgrade in the location of Woodburn nor any timeframe. There were no other traffic management works currently occurring within Evans Head. This is reflective of the relatively low traffic flows in this location. Apart from the shared pathway along Evans Head Road, there are no footpaths within the general locality of the subject site, reflective of the low pedestrian and vehicle demands in the locality. Pedestrians are able to walk along the verges or side of the road as required. In a similar manner, cyclists are also able to ride on the road due to the low traffic speeds and volumes. 4 Item 2.2.5 Public Transport Comment Evans Head is serviced by Northern Rivers Buslines including Ballina Buslines which provide two routes, Route 660 Evans Head to Ballina and Route 690/695 Grafton to Lismore via Evans Head. These services do not operate of a weekend or public holidays. The service between Evans Head and Ballina provides two outbound services in the morning (7.20 and 11am) and two return services, one in the late morning and one in the afternoon. The service to Lismore allows for two morning and one afternoon outbound service with one morning and two afternoon services inbound from Lismore. The Grafton to Lismore via Evans Head however only provides a single morning service (9.10am) and a single return service (3.35pm). Transport NSW Trainlink also provides a bus service to Evans Head between Grafton and Byron Bay. This daily service picks up/drops off passengers northbound in the early evening (8pm) whilst southbound passengers are picked up/dropped off at 6.45am. This service provides coach connection with the Sydney rail service at Grafton. Carpooling is encouraged in the Richmond Valley through the promotion of the Northern Rivers carpooling scheme. This is a free online service connecting people wishing to travel together to the same endpoints. In major destinations such as hospitals and TAFEs it also includes priority parking options. 2.3 Traffic Flows 2.3.1 Daily Traffic Flows As part of the project work, Seca Solution collected traffic data on Evans Head Road in the vicinity west of Currajong Street to determine the peak and daily flows on this road. These surveys were completed on Friday 12th December 2014. The surveys were completed between 7.30 and 9.30 AM and then 2.30 to 6.00 PM. The peak flow during the AM period was between 8.30 and 9.30 when the 2-way flow on Evans Head Road was 266 vehicles. The peak flow in the PM period was between 4.00 and 5.00 when the flow was 266 vehicles per hour. Based upon peak flows typically representing 10% of the daily flows, this would indicate that the daily flows would be in the order of 2,700 vehicles per day. Traffic flows on the other roads including Currajong Street in the locality would be much lower, due to dispersed trips over a number of different roads. These flows reflect the low number of residents in this location and the potential for a significant number of the resident within Evans Head to be retired from full time work. 5 Item 2.3.2 Daily Traffic Flow Distribution 2.3.3 Vehicle Speeds 2.3.4 Existing Site Flows 2.3.5 Heavy Vehicle Flows 2.3.6 Current Road Network Operation 2.4 Traffic Safety and Accident History 2.5 Parking Supply and Demand 2.5.1 On-street Parking Provision 2.5.2 Off-street Parking Provision 2.5.3 Parking Demand and Utilisation 2.5.4 Set down or pick up areas 2.6 Public Transport 2.6.1 Rail Station Locations 2.6.2 Bus Stops and Associated Facilities Comment Daily traffic flows along Evans Head Road would be reasonably balanced over the day. The peak hour surveys show a bias in traffic westbound on Evans Head Road in the morning with the opposite in the afternoon period. This would be reflective of work and school trips towards Woodburn and the Pacific Highway. No speed surveys were completed as part of the study work. However, observations on site indicate that drivers typically travel within the speed limits due to the interaction with other vehicles, driveways and the side roads within Evans Head. The straight alignment and low traffic volumes on Evans Head Road could potentially encourage drivers to travel above the posted speed limit of 80 km/h on Evans Head Road to the west of Evans Head. The subject development land within the site is currently vacant and therefore develops no traffic movements. There are a very limited number of heavy vehicles on Evans Head Road and within Evans Head, reflective of very little demand within the township and the lack of through route for traffic. There is a demand for Council refuse trucks servicing the locality as well as delivery vehicles associated with the demands within the town centre. During the site work there were very few heavy vehicle movements along Evans Head Road, typically representing 2-3% of the total traffic flows. These vehicles comprised of vehicles delivering products to the local business in Evans Head only. Observations on site during the morning and afternoon peak periods show that the road network in the vicinity of the subject site operates very well, with no delays or congestion for existing road users. Traffic accident data provided by the RMS for the locality shows that there has been just 3 accidents in the vicinity of the site over the past 5 year timeframe. These accidents all occurred at the roundabout controlled intersection of Evans Head Road and Currajong Street. This roundabout is located at the end of a long straight section of road and enforces the speed limit change from 80 km/h to 50 km/h – although it is considered that vehicles will travel at a higher speed than the 80 km/h on the approach. None of these accidents created any serious injuries with one of them related to fatigue with a single vehicle involved running off the road. Overall it is considered that the local roads in and around Evans Head offer a safe road environment. Parking is permitted on both sides of the roads within the general locality of the site as well as along Evans Head Road. The majority of residential dwellings in Evans Head have off street parking. In the centre of town there is on-street parking available for customers of the various commercial outlets in this location. Other than in the centre of Evans Head there is very little demand for parking. The majority of parking demands are met off road. There are no set down or pick up areas in the vicinity of the site. This area is not serviced by train lines with the closest service at Grafton. There are no bus stops in the locality of the site. All services operate as Hail and Ride. 6 Item 2.6.3 Pedestrians 2.7 Other Proposed Developments 3.1 The Development 3.1.1 Nature of Development 3.1.2 Access and Circulation Requirements 3.2 Access 3.2.1 Driveway Location 3.2.2 Sight Distances 3.2.3 Service Vehicle Access 3.2.4 Queuing at entrance to site Comment There are no footpaths within the locality of the site and generally within Evans Head. The only footpaths are provided within the central commercial centre of Evans Head. No other significant developments noted. The development will allow for a partial re-development of the site to allow for a 27 lot residential subdivision with direct access off Evans Head Road, together with a hotel with upto 90 beds and a 90 lot residential subdivision off Currajong Street. All vehicles will enter and exit the site in a forward direction direct off Evans Head Road or Currajong Street as appropriate. A new access will be provided on Evans Head Road to provide access to the proposed residential subdivision. This access will allow for all turning movements and will be designed and constructed in accordance with Council requirements. A new access will be provided on Currajong Street in the vicinity of Tuckeroo Crescent. This intersection will form a 4-way intersection and will be a roundabout to allow for all turning movements as well as maintaining safety. Whilst a 4-way giveway controlled intersection has been considered, a roundabout is more appropriate on road safety grounds and will act as a speed control device. The location of the internal driveways to the individual lots and the hotel will be the subject of a separate DA. They will all be designed and constructed in accordance with Council requirements. Evans Head Road offers a straight alignment offering good visibility in both directions, for vehicles entering and exiting the site as well as for through traffic movements on Evans Head Road. Evans Head Road, in the locality of the proposed site access operates under a posted speed limit of 80 km/h and Austroads Guidelines indicates the safe intersection sight distance requirement is 160 metres. This distance has been checked on site and the sight distance exceeds 200 metres in both directions. If Council consider the urban speed limit of 50 km/h should be extended to this location (in consultation with the RMS) then the sight visibility distances would be decreased and road safety increased further. For the access on Currajong Street, the posted speed limit is 50 km/h and the safe intersection sight distance is 80 metres. The sight distance available in the location of the proposed site access exceeds 200 metres in both directions, which would allow for safe entry and exit movements. Note that with the construction of a 4-way roundabout at this location the sight distance requirements would be reduced further due to the low traffic speeds through the roundabout. There is no specific service vehicle access required for the residential subdivision. There will however be the requirement for occasional larger vehicles associated with deliveries and these will be able to be accommodated within the internal roads. These roads will be designed and constructed in accordance with Council requirements which allowing for access for these occasional vehicles. There will be a requirement for servicing for the hotel site e.g. laundry, supplies etc. and these will typically be via large vans. These large vans have similar characteristics to a large car / 4WD and as such can be accommodated within the development site via the proposed access point off Currajong Street. It is considered that there will be few, if any delays, for traffic entering and exiting the site, given the low traffic flows on the adjacent road network and the low flows associated with the proposed development. 7 Item 3.2.5 Comparison with existing site access 3.2.6 Access to Public Transport 3.3 Circulation 3.3.1 Pattern of circulation 3.3.2 Road width 3.3.3 Internal Bus Movements 3.3.4 Service Area Layout 3.4 Parking 3.4.1 Proposed Supply 3.4.2 Authority Parking 3.4.3 Parking Layout 3.4.4 Parking Demand 3.4.5 Service Vehicle Parking 3.4.6 Pedestrian and Bicycle Facilities 4.1 Traffic Generation Comment Any delays for drivers exiting the site will allow for containment of vehicles within the site with no impact upon the external road network. The site is currently vacant over a large portion and generates low traffic flows. There is some limited use of the air strip and a Mens shed on the site which generate some traffic in and out of the site. There are no bus stops within the locality of the subject site. Bus services along Evans Head Road operate as Hail and Ride. All vehicles will be able to enter and exit the site in a forward direction, with the internal site layout designed in accordance with Council requirements. All internal roads will be designed in accordance with the Council requirements within the DCP and allow for 2-way traffic movements as required. There may be a requirement to allow for bus access to the hotel site, to cater for group travel. The design of the roads in accordance with Council DCP requirements allows for these larger vehicles, which have a similar operating characteristics to a Council refuse collection vehicle. A service area will be provided for the hotel, to allow for delivery of linen and general supplies. This service area will be design in accordance with AS2890 Part 2 and allow for a maximum vehicle size of a large rigid truck (length 12.5 metres). The car parking supply will be determined as part of the DA process for the various elements within the overall development.
