A call was made for nominations for Chair. A. Featherstone was nominated and accepted the nomination. Moved by A. Merry Seconded by W. Caston That the nominations for Chair of the Ecological and Environmental Advisory Committee be closed. Carried A. Featherstone was acclaimed as Chair. A call was made for nominations for Vice-Chair. A. Merry was nominated and accepted the nomination. Moved by W. Caston 1581268 2 2 EEAC -2- 14/02/25 Seconded by A. Dean That the nominations for Vice-Chair of the Ecological and Environmental Advisory Committee be closed. Carried A. Merry was acclaimed as Vice-Chair. A. Featherstone assumed the Chair. Introduction Of New Member: Eduardo Cejudo E. Cejudo introduced himself to the Committee. He stated that he was excited to join and looks forward to working with the Committee. The Committee members provided self introductions. Declarations of Pecuniary Interest Under The “Municipal Conflict Of Interest Act” Chair A. Featherstone declared a conflict in regards to items 4(a), 4(b), 5(a) and 5(b) due to her employment. *A. Featherstone left the meeting at 6:40 p.m. Vice-Chair A. Merry assumed the Chair. Minutes: December 17, 2013 Moved by C. Millar Seconded by A. Woroch THAT the minutes of the Ecological and Environmental Advisory Committee of December 17, 2013 be approved. Carried Reports a) EEAC-14-001, River Road Extension Class Environmental Assessment: Comments on Proposed Alignment 5 Wayne Cheater, Senior Project Manager, provided a presentation on the latest option for the proposed River Road extension. A copy of the presentation is appended to the original minutes. He explained that the latest option will consist of a four lane road with multi-use trails on either side that will address the current traffic issues and minimize the effect on the Hidden Valley area. He outlined the measures that staff are proposing to mitigate the environmental impacts of the project including minimizing the loss of Provincially Significant Wetland and low vertical walls in the Hidden Valley area to prevent Jefferson Salamanders and small animals from entering the road. 1581268 3 3 EEAC -3- 14/02/25 Daphne Nicholls, Kitchener, appeared to provide a presentation encouraging the Committee to oppose the extension of River Road. A copy of the presentation is appended to the original minutes. She explained that while the latest option impacts the woods and wetlands less than any previous plans she remains opposed to the project for various reasons. G. Michalenko presented the subcommittee’s report. He provided an overview of the history of the project and noted that the subcommittee is happy that option 5 has the River Road extension running closer to Highway 8. The subcommittee noted that the section of the wetland that would be removed contains a population of Phragmites which poses a danger to the rest of the wetland. Two small creeks flow into the wetland from the proposed road alignment, and there is therefore a need to keep chloride from road salting out of the wetland in winter months. He noted that it is a complex issue but that option 5 represents an improvement over option 4. C. Millar noted that due to personal reasons she has not been active with the subcommittee. In response to a question from the Committee, W. Cheater stated that there will be a substantial area of trees that will be removed but that native trees will be replanted as a part of an offsetting reforestation project. He also noted that staff are aware that land in the area is owned by private developers but that staff are unaware of any specific plans they may have for the land. C. Gosselin noted that most of the trees to be removed are located in a small woodland adjacent to Highway 8 rather than in the more ecologically significant woodlands within the Hidden Valley Core Environmental Feature. Moved by C. Millar Seconded by A. Dean That the Ecological and Environmental Advisory Committee advise Planning, Housing, and Community Services staff that: a. proposed new Alignment 5 poses fewer potential adverse environmental impacts on the Hidden Valley Core Environmental Feature than previous preferred new road alternatives; b. proposed Alternative 5 may be adopted pursuant to Regional Official Policies Plan Policies 4.3.17 and 4.4.9 and Regional Official Plan policy 7.C.12(c); and c. the Ecological and Environmental Advisory Committee continue to be involved in the review of the detailed design of the proposed new road at a subsequent stage in the Environmental Assessment process. Carried 1581268 4 4 EEAC b) -4- 14/02/25 EEAC-14-002, Proposed Cambridge Aggregates Pit, 1830 Wrigley Road, North Dumfries Township, Cedar Creek Spillway [E.S.P.A. 41], McCrone Lake [E.S.P.A. 46] Bob Long (Long Environmental) and Ken Zimmerman (Essroc Cambridge Aggregates) appeared before the Committee to note that they are largely satisfied with the subcommittee’s report. B. Long explained that the request in section 3.2 of the subcommittee’s recommendation to clear the natural regeneration area of “nonindigenous species such as Common and/or Glossy Buckthorn” would require warmer weather before the area could be evaluated. It was also noted that Buckthorn can be very difficult to clear entirely. The Committee agreed to change the wording of 3.2 to reflect the need to “control” rather than “clear” the Buckthorn. B. Long explained that timing requested in 3.4 would not be possible. He stated that the soil required for the oak savanna would not be available until stage two of the project. This is due to the soil from stage one being required for berms. The soil from stage two will be used for berms as well as the oak savanna area but B. Long could not commit to it being completed within the time frame noted in 3.4. The Committee agreed to remove 3.4 from the recommendation. B. Long noted that they planned to create four turtle nests and stone piles for snake and small mammal habitats and suggested that the subcommittee assist with locating the areas. The Committee agreed to reflect this in the recommendation. B. Long noted that they were not prepared to undertake the extended groundwater monitoring requested in 3.11. He felt that this request was excessive given that it is a relatively small pit that is above the water table. The Committee agreed to remove 3.11 and requested that well water at neighbouring properties be tested if the property owners agreed. B. Long agreed to ask neighbours that are within 100-150 metres but noted that in other projects many property owners do not agree to have their water tested. B. Long noted that in their plans the “enhancement” plan and area referred to in 3.5 and 3.12 is called the “rehabilitation” plan and area. The Committee agreed to change the term in the recommendation. Moved by C. Priddle Seconded by G. Michalenko That the Ecological and Environmental Advisory Committee provide the following advice to Community Planning staff with respect to the proposed zone change and aggregate licence on part of the lands at 1830 Wrigley Road, North Dumfries Township on lands contiguous to the Cedar Creek Spillway Environmentally Sensitive Policy Area [E.S.P.A. 41] and the Dumfries Carolinian Environmentally Sensitive Landscape. 1581268 5 5 EEAC -5- 14/02/25 1. that the scoped Environmental Impact Statement required in support of the proposed zone change and aggregate licence application pursuant to Regional Official Policies Plan Policies 4.2.7, 4.3.13, and 4.4.5 and Regional Official Plan Policies 7.B.12, 7.C.9 and 7.G.4(b) satisfactorily fulfills the Terms of Reference adopted on August 13, 2013, and that the Committee has no objection in principle to the approval of the required zone change application. 2. that the boundary of the Cedar Creek Environmentally Sensitive Policy Area [E.S.P.A. 41] be interpreted as shown on Attachment 1 such that it follows the southern rim or the main kettle feature and also includes the small kettle feature on the western boundary of the subject property; 3. 2.1 that only the proposed extraction area be re-zoned to permit aggregate extraction, and that the Cedar Creek Environmentally Sensitive Policy Area and the recommended buffer strip be re-zoned for environmental conservation pursuant to Regional Official Policies Plan Policy 4.3.6 and Regional Official Plan policy 7.A.2; 2.2 that the ‘taking of water’ be specifically excluded from the re-zoning; Advise Community Planning staff that the Region request the Ministry of Natural Resources to consider including the following in the Site Plan of the proposed Class A, Category 3 Pit Licence: 3.1 That a detailed planting plan for the 1.8 hectare tableland area between the Limit of Extraction boundary and the kettle feature be prepared in consultation with the Region; 3.2 That invasive non-indigenous species such as Common and/or Glossy Buckthorn in the natural regeneration area be controlled before allowing natural successional processes to proceed; 3.3 That planting of the oak savanna component of the Enhancement Plan outside the Limit of Extraction boundary start within five years of Licence approval, and be completed prior to commencement of Stage 2 extraction; 3.4 That planting of the oak savanna component of the Rehabilitation Area inside the Limit of Extraction boundary in Stage 2 be completed at least two years before the Licence is surrendered; 3.5 That exclusion fencing be installed along the northern edge of the Limit of Extraction boundary to deter turtles from the kettle feature from entering the pit to find nest sites; 3.6 That at least four stone piles be created within the buffer area to provide habitat for snakes and small mammals; 1581268 6 6 EEAC 4. -6- 14/02/25 3.7 That at least four areas of turtle nesting habitat be created on a southfacing slope within the buffer area using methods recommended by the Toronto Zoo; 3.8 That the Site Plan notes contain detailed erosion and sedimentation control measures; 3.9 That a groundwater monitoring programme as described in section 13.6 of the Goodban report be implemented, subject to the following revisions; 3.10 That a detailed ecological monitoring program be established, in consultation with the Region to monitor the ecological integrity of contiguous portions of Environmentally Sensitive Policy Area 41, as well as the progress of the plantings within the Rehabilitation Areas inside and outside the Limit of Extraction boundary, and that such monitoring plan also document remedial actions undertaken to address previously-noted deficiencies in meeting the targets of the approved Rehabilitation Plan; 3.11 That the results of water resources and ecological monitoring be reported by a qualified professional on an annual (calendar year) basis to the M.N.R., Township, GRCA and Region by April 30 of the year following.

Carried *A. Featherstone returned to the meeting at 8:23 p.m. A. Featherstone assumed the Chair. *A. Merry left the meeting at 8:23 p.m. c) EEAC-14-003, Regional Forest Management Plan: Operating Management Plan for Gibney Regional Forest [ESPA13] Albert Hovingh, Principal Planner, provided a presentation outlining the draft operating plan for Gibney Regional Forest. A copy of the presentation is appended to the original minutes. He provided an overview of the different areas of the forest and the species found within it. Some of the key issues for the forest include deciding whether to remove or manage the conifer plantation, how to ensure stability in the short and long term for the sandy slope adjacent to Sandhills Road, identifying the entrance to the forest, and possibly creating a short walking loop. A. Featherstone, A. Woroch, A. Dean, C. Priddle, L. Ehnes and C. Millar expressed interest in participating in the subcommittee. Moved by C. Priddle 1581268 7 7 EEAC -7- 14/02/25 Seconded by G. Michalenko That the Ecological and Environmental Advisory Committee: a) receive the Draft Operating Management Plan for Gibney Regional Forest as attached to Report EEAC-14-003, dated February 25, 2014, and b) strike a subcommittee to review proposed property and forest management activities on-site and make recommendations as necessary. Carried Information/Correspondence a) P-14-020, The Cornerstone Standards Council’s Draft Responsible Aggregate Standards – Regional Comments Chris Gosselin, Manager, Environmental Planning, noted that he has been sitting on the Cornerstone Standards Council’s Standards Development Panel which is responsible for drafting the standards. He noted that a colleague rather than he drafted this report. He explained that the report had been accepted at Planning and Works Committee and would be submitted to Regional Council on February 26, 2014 and if approved would constitute the Region’s comments of the draft standards. Committee members are welcome to submit their own comments on the draft standards directly to Cornerstone. In response to a question from the Committee, C. Gosselin stated that the final standards will be purely voluntary. Aggregate operations, not necessarily firms, that are certified will be able to market their products as socially and environmentally responsible aggregate in a manner similar to Forest Sustainability Council forest products. He also noted that these standards are the first draft. The Standards Development Panel will re-convene after the circulation period to review all the comments and prepare a final draft to be released in the summer or fall of 2014. Received for information. Other Business W. Caston informed the Committee that the new Provincial Policy Statement was released on February 24, 2014 and will come into effect on April 30, 2014. Active EEAC Subcommittees C. Gosselin noted that the scoped EIS reports for the Granval Industrial Subdivision and the Bosdale Subdivision have been received and reports on the projects will be coming to the Committee in the near future. The snowy winter has delayed site visits by the respective sub-committees. Received for information. 1581268 8 8 EEAC -8- Next Meeting: March 25, 2014 Adjourn Moved by A. Dean Seconded by C. Priddle That the meeting adjourn at 9:05 p.m. Carried Committee Chair, A. Featherstone Committee Clerk, T. Brubacher 1581268 14/02/25 9 9 Report: EEAC-14-004 Region of Waterloo Planning, Housing, and Community Services Community Planning To: Chair Allison Featherstone and Members of the Ecological and Environmental Advisory Committee Date: May 27, 2014 File Code: D04-20025 Subject: Proposed Mixed Use Development, Fairway Road and Lackner Boulevard, City of Kitchener, Lackner Woods [ESPA 25] and Core Environmental Feature Recommendation: That the Ecological and Environmental Advisory Committee advise Planning, Housing and Community Services staff as follows: 1. That the Chicopee Hills, Kitchener (Fairway Rd. / Lackner Blvd.) Environmental Impact Study (Stantec, February 26, 2014) is generally acceptable, and the Committee has no objection in principle to the approval of proposed Zone Change Application ZC14/04/L/AP within and contiguous to Lackner Woods (ESPA 25) and Core Environmental Feature, subject to the following conditions: a) That the southern boundary of the Lackner Woods Environmentally Sensitive Policy Area (ESPA 25) and Core Environmental Feature be interpreted to include the Forb Mineral Marsh (Unit MAM2-10a) and the Dry-Fresh White Cedar Mixed Forest (Unit FOM4) as shown on Figures 2 and 3 of the Chicopee Hills, Kitchener (Fairway Rd. / Lackner Blvd.) Environmental Impact Study (Stantec, February 26, 2014) following field verification by a sub-committee of the Ecological and Environmental Advisory Committee on May 8, 2014., and that the area of Cottonwoods to be retained be considered an appropriate buffer to the ESPA/Core Environmental Feature from the proposed development. b) That ESPA 25, the Core Environmental Feature and associated buffers on the subject lands be placed in suitable conservation open space zoning (P-2) as shown on Map No. 1 of the Zone Change Application, pursuant to Policy 7.A.2 of the Regional Official Plan. 1639422 Page 1 of 14 10 10 May 27, 2014 Report: EEAC-14-004 2. That the City of Kitchener consider implementing the following conditions through the site plan approval process: a) That no clearing of vegetation occur on the site during the bird breeding season (May 1 - July 31) in compliance with the “Migratory Birds Convention Act” unless it can be ascertained by a qualified expert to the satisfaction of the City of Kitchener that no birds covered by the Act are observed to be breeding in or adjacent to the affected area. b) That prior to any land clearing, grading or other site alteration, the owner ensure compliance with the “Endangered Species Act.” c) That, prior to site plan approval or any site alteration, the owner install permanent fencing along the Tree Protection Line as identified on the proposed master plan (GSP Group, January 28, 2014) and along the boundary of the stormwater management area in the southeastern corner of the site with signage identifying the Lackner Woods Environmentally Sensitive Policy Area and Core Environmental Feature to the satisfaction of the City of Kitchener in consultation with the Region. d) That, prior to any land clearing, grading, or the installation of services, the owner submit a detailed erosion and sediment control plan acceptable to the City of Kitchener and the Grand River Conservation Authority in order to prevent sedimentation into ESPA 25 and Core Environmental Feature. e) That, prior to site plan approval, the owner submit a detailed stormwater management plan, to the satisfaction of the City of Kitchener and the Grand River Conservation Authority. f) That, prior to site plan approval, any wells on site be decommissioned in compliance with applicable regulations to the satisfaction of the City of Kitchener in consultation with the Region of Waterloo. g) That, prior to site plan approval the Cottonwoods within the area to be retained be assessed by a certified arborist in terms of health and structural soundness, and that any trees that could pose a hazard to the adjoining future school be appropriately pruned or removed, if necessary. h) That, prior to site plan approval, the owner submit landscaping and planting plans for all buffer areas contiguous to ESPA 25 and the Core Environmental Feature and for the stormwater management area, and that recommended plantings consist of locally-appropriate, self-sustaining native vegetation to the satisfaction of the City of Kitchener in consultation with the Region. i) That, prior to site plan approval, the owner submit a detailed monitoring plan for ESPA 25, the Core Environmental Feature and adjoining stormwater management facility on the subject lands as outlined in the Chicopee Hills, 1639422 Page 2 of 14 11 11 May 27, 2014 Report: EEAC-14-004 Kitchener (Fairway Rd. / Lackner Blvd.) Environmental Impact Study (Stantec, February 26, 2014) to the satisfaction of the City of Kitchener, GRCA, and Region. j) That the owner consider dedicating through consent the portion of ESPA 25, the Core Environmental Feature and associated buffers areas on the subject lands to the City of Kitchener. k) That, prior to site plan approval, the owner submit a detailed stewardship management plan to the City of Kitchener in consultation with the Region for the portion of ESPA 25 and the Core Environmental Feature within the subject lands including but not limited to removal and/or control of invasive species and retention of Virginia Stickseed, only if these natural areas are not dedicated to the City of Kitchener. l) That, prior to site plan approval, the owner develop a brochure and other information tools for new residents which provides information about the natural heritage features contiguous to the site along with advice about how they can be good stewards of these areas, and that the brochure be to the satisfaction of the City of Kitchener, Ministry of Natural Resources and Grand River Conservation Authority. m) That, prior to site plan approval, the owner remove any debris/furniture from ESPA 25 and the Core Environmental Feature within the subject lands, in addition to the stone fence along the eastern property boundary, to the satisfaction of the City of Kitchener in consultation with the Region. Report: On September 25th 2012, EEAC approved the recommendation in report EEAC-12-008 that a subcommittee be established to review the required Environmental Impact Statement (EIS) for the proposed mixed use development located at the northeast corner of Lackner Boulevard and Fairway Road in Kitchener. The subject lands are within and contiguous to the Lackner Woods Core Environmental Feature and Environmentally Sensitive Policy Area (ESPA 25) (see Figure 1). Currently, the lands are owned by the Waterloo Region District School Board (WRDSB) and the proposal for the lands includes an elementary school and playing fields as well as a mix of residential and commercial buildings and associated parking areas for all uses. In October 2012, following discussions among Regional environmental staff, City of Kitchener staff, and the applicant, it was determined that review the proposed development would occur in two phases. Since Regional Official Plan (ROP) Policy 7.C.8 prohibits development or site alteration within a Core Environmental Feature, the first phase in the review of the application was for EEAC to interpret the boundary of the Core Environmental Feature on the subject property in accordance with Policy 7.A.6. This will define a development envelope to guide site planning for the subject lands in Phase 2. This approach was necessitated by the fact that the boundary of the feature contiguous to the site had become indistinct since it was last interpreted due to the 1639422 Page 3 of 14 12 12 May 27, 2014 Report: EEAC-14-004 growth of a grove of poplars. To this end, EEAC passed the following recommendations at its August 13, 2013 meeting (see EEAC 13-009): a) That in order to interpret the boundary on the subject property of the Lackner Woods Core Environmental Feature consisting of Environmentally Sensitive Policy Area 25, the Idlewood Creek Provincially Significant Wetland, and an associated Significant Woodland, it is first necessary to confirm whether the poplar trees at the northern end of the property are Regionally significant Eastern Cottonwood or a Carolina Poplar hybrid. b) That if the poplars are confirmed to be Regionally significant Eastern Cottonwood, the boundary of the Significant Woodland component of the Lackner Woods ESPA/Significant Woodland be interpreted to retain some part of the population on site, so that this species continues to be represented in the Core Environmental Feature. c) That if some of the poplar population is retained, reasonable effort should also be made to retain the habitat of the Regionally significant Virginia Stickseed (Hackelia virginiana) within the refined boundary or buffer, and that if it is determined that all or part of the poplar grove may be removed, reasonable efforts be made to relocate the Virginia Stickseed to suitable habitat within ESPA 25. d) That staff seek clarification from the Grand River Conservation Authority as to whether the small pond in the eastern corner of the site warrants inclusion within the PSW boundary. The consultant team for the proposed development has now had the opportunity to study these issues and have submitted the following documents in support of the application, which have been reviewed by the subcommittee: - Chicopee Hills, Kitchener (Fairway Rd./Lackner Blvd.) Environmental Impact Study (Stantec Consulting Ltd., February 26, 2014) - Chicopee Hills, Kitchener (Fairway Rd./Lackner Blvd.) Functional Servicing and Stormwater Management Report (Stantec Consulting Ltd., February 2014) - Fairway Lackner Site – Wetland Hydrologic Assessment (Stantec Consulting Ltd., February 27, 2014) - Master Plan, Chicopee Hills (GSP Group, January 28, 2014) In addition, on May 8, 2014, a representative from the subcommittee (Andrew Dean) met on site with staff from Regional environmental planning, the City of Kitchener, Grand River Conservation Authority and the consultant team to verify the boundary of 1639422 Page 4 of 14 13 13 May 27, 2014 Report: EEAC-14-004 and buffers to ESPA 25 and the Core Environmental Feature within the subject lands. The subcommittee finds that the EIS is generally acceptable and conforms to the Terms of Reference for the study as outlined in the following sections. 1. Boundary of Lackner Woods Core Environmental Feature Significant natural features on the subject lands and recommended buffers are shown on Figure 3 of the EIS (reproduced in Figure 2 of this report). The Core Environmental Feature consists of three components which partially, but not completely overlap. a) ESPA 25 Designated in 1976, the Lackner Woods ESPA is a Provincial Area of Natural and Scientific Interest (ANSI) and is approximately 36 hectares in size. It includes a large Sugar Maple-Beech-Hemlock forest located on hilly topography around a large central swamp forest of Black Ash, Yellow Birch, White Cedar and Silver Maple. Idlewood Creek flows in a southeastern direction through the ESPA and is the primary hydrological feature draining the associated Provincially Significant Wetland complex (see Figure 1). The southwestern boundary of the ESPA on the subject property was interpreted by Regional staff in 1994 in anticipation of a development application. The application did not materialise at that time, and over the intervening 19 years, the feature boundary has altered significantly through natural succession. In summary, the subcommittee finds the ESPA boundary on Figure 3 of the EIS acceptable. b) Idlewood Creek Provincially Significant Wetland and Other Wetlands Subsequent to the designation of the ESPA, the Province identified portions of the subject lands as the Idlewood Creek Provincially Significant Wetland (PSW), generally located in the northern and eastern parts of the property. Most of the wetland complex, with two exceptions, is within ESPA 25. The PSW boundary extends in a western direction towards Lackner Boulevard in the northern part of the site. The PSW also extends towards a small pond in the eastern corner of the site adjacent to Fairway Road. In addition, a small non-PSW wetland pocket is located in the southern corner of the property adjacent to the intersection of Lackner and Fairway (see Figure 1). The removal of this small wetland has been proposed as part of the site’s development pursuant to GRCA policies. Recognising that the delineation of PSWs is ultimately the responsibility of the Ministry of Natural Resources and that it is often carried out in the field by GRCA staff, the subcommittee accepts the delineation of wetlands on the subject lands as shown on Figure 3 of the EIS. With respect to the small pond in the eastern corner of the site, the subcommittee recommended previously that the wetland be evaluated to determine whether it should be included within the PSW. To date, this evaluation by MNR and GRCA has not 1639422 Page 5 of 14 14 14 May 27, 2014 Report: EEAC-14-004 occurred. In addition, the EIS presents a rationale for removal of this wetland based on the GRCA’s wetland removal policy. Regional environmental planning staff has followed-up with GRCA staff on this issue but to date GRCA staff has not issued comments on the consultant’s evaluation contained in the EIS. c) Significant Woodland As previously mentioned, the southwestern boundary of the Lackner Woods ESPA has changed over time through natural succession. In 2009, the new ROP designated a Core Environmental Feature (Significant Woodland) over the ESPA, a designation which extends beyond the interpreted 1994 ESPA boundary to include a Poplar/Cottonwood grove (see Photo 1 and Figure 1). At issue with respect to this application is whether or not the grove should be considered part of a larger Significant Woodland and therefore part of the Core Environmental Feature and/or ESPA. Policy 7.A.6 of the ROP directs that boundaries of Core Environmental Features be interpreted through the review of EISs. Confirmation of the boundary on this site will then facilitate evaluation of whether potential removal of all or part of the woodland would result in an adverse environmental impact to the Core Environmental Feature. Photo 1: Cottonwood Grove within Core Environmental Feature (Significant Woodland) (Photo: Tim Van Hinte, Region of Waterloo, May 8, 2014) 1639422 Page 6 of 14 15 15 May 27, 2014 Report: EEAC-14-004 Section 4.5.2 of the EIS (p.4.4), (Vegetation Communities) describes the poplar grove as a Mineral Cultural Woodland (CUW1) based on the Ecological Land Classification (ELC) for Southern Ontario: The canopy is open in many sections throughout the community. The canopy is dominated by Eastern Cottonwood (Populus deltoides) with occasional associates of Black Locust (Robinia pseudo-acacia) and Crack Willow (Salix euxina). Manitoba Maple (Acer negundo) is an abundant component of the sub-canopy. The understory is dominated by Glossy and European Buckthorns, as well as Riverbank Grape (Vitis riparia). The ground layer is densely covered by weedy species including Garlic Mustard (Alliaria petiolata), Canada Goldenrod (Solidago canadensis), Dame’s Rocket (Hespersis matronalis) and seedlings of Glossy and European Buckthorn. In addition, the subcommittee notes that a population of Regionally significant Virginia Stickseed (Hackelia virginiana) has been observed within the poplar grove (see page 4.6 of the EIS). Staff advise that this species was previously noted in ESPA 25 in a 1996 floristic survey carried out for one of the adjoining subdivisions. To this end, at its August 13, 2013 meeting, EEAC asked the proponents to confirm whether or not the trees within the Significant Woodland were in fact Eastern Cottonwoods, a Regionally significant species if native-occurring (see EEAC 13-009). In addition, EEAC recommended that if the poplars are confirmed to be Eastern Cottonwood, the boundary of the Significant Woodland component of the Lackner Woods ESPA/Significant Woodland be interpreted to retain some part of the population on site, so that this species continues to be represented in the Core Environmental Feature. Subsequently, the consultants confirmed, through genetic testing, that the trees were in fact Eastern Cottonwoods (see page 4.6 of the EIS). Furthermore, the consultant team completed a Detailed Vegetation Plan for the lands which resulted in a preservation plan for the Cottonwoods. In summary, the proposed Tree Protection Area will protect 65 of 163 Eastern Cottonwoods (40%) within the woodland which is consistent with the recommendation in EEAC Report 13-009. Considering the nature of the habitat in which the Cottonwoods are growing and the representative population to be preserved, the subcommittee is satisfied with the revised boundary of the Significant Woodland and no adverse environmental impacts are anticipated as this population of Cottonwoods will be protected in perpetuity. Having reviewed the EIS, the sub-committee recommends that staff consider revising the southern boundary of the Lackner Woods ESPA/Core Environmental Feature to include the Forb Mineral Marsh (Unit MAM2-10a) and the Dry-Fresh White Cedar Mixed Forest (Unit FOM4). The Cottonwoods to be retained will in effect form the required ten metre buffer to the ESPA. The trees observed on May 8, 2014 were relatively young and for the most part in good condition. We did, however, notice a few which might have some structural defects. Given the rapid growth of this species and the large size at full maturity, the subcommittee recommends that, as part of the site preparation process contiguous to the retained woodland, the trees within the area be assessed by a certified arborist in terms 1639422 Page 7 of 14 16 16 May 27, 2014 Report: EEAC-14-004 of health and structural soundness. Any trees that could pose a hazard to the adjoining school should be appropriately pruned or removed, if necessary. 2. Delineation and design of buffers around ESPA 25 and Core Environmental Feature Proposed buffers from ESPA 25 and Core Environmental Features on the property are shown on Figure 3 of the EIS. Buffers of 20-30 metres from the Idlewood Creek PSW and 10 metres from the ESPA/Significant Woodland boundary have been applied. In summary, the subcommittee is satisfied with the proposed buffers and finds that the proposal conforms to ROP Policy 7.C.10. In addition, the subcommittee recommends that ESPA 25, the Core Environmental Feature and associated buffers on the subject lands be placed in suitable conservation open space zoning (P-2) as shown on Map No. 1 of the Zone Change Application (City of Kitchener, April 9, 2014) pursuant to Policy 7.A.2 of the Regional Official Plan. 3. Biophysical survey of natural habitats and species Various field surveys were conducted on the subject lands between 2008 and 2013 including but not limited to Ecological Land Classification (ELC), vascular flora inventories, breeding bird surveys, wetland delineation, and reptile surveys. The subcommittee is of the opinion that the type and frequency of biophysical surveys undertaken by the consultant is consistent with the “Region of Waterloo Greenlands Network Implementation Guideline” with respect to a scoped EIS. Noteworthy results of the various surveys are as follows: Four (4) Regionally significant plants/trees were observed: Eastern Cottonwood, Hackberry, Rough Sedge, and Virginia Stickseed. Three (3) Regionally significant birds were observed: Brown Creeper and Swamp Sparrow (both possible breeders) and Osprey (flyover, no suitable habitat). Other bird species of conservation concern observed previously within ESPA 25 by Ecoplans circa 1995 include Chimney Swift, Wood Thrush, Red-headed Woodpecker, Swainson’s Thrush (Regionally significant), Ovenbird and Scarlet Tanager. Due to the presence of several Regionally significant breeding birds, the subcommittee recommends that no clearing of vegetation on the site occur during the bird breeding season in compliance with the “Migratory Birds Convention Act”, unless it can be ascertained by a qualified expert that no birds covered by the Act are observed to be breeding in or adjacent to the affected area. In addition, the subcommittee recommends that prior to any land clearing, grading or other site alteration, the applicant ensure compliance with the “Endangered Species Act.” In addition, the subcommittee recommends that appropriate fencing be installed to limit intrusion from the future development into the ESPA. It is expected that the school board will require fencing around the schoolyard. 1639422 Page 8 of 14 17 17 May 27, 2014 Report: EEAC-14-004 In summary, the subcommittee is satisfied with the level of habitat protection as ESPA 25 and the Core Environmental Feature on and contiguous to the subject lands will be protected and afforded suitable buffers from proposed development. 4. Hydrological and hydrogeological regimes sustaining ESPA 25 and Core Environmental Feature In summary, the following hydrological features are located within or contiguous to the subject lands: Idlewood Creek (east branch) flows in a southeasterly direction contiguous to the subject lands, across Fairway Road, eventually spilling into the Grand River; Idlewood Creek PSW complex is located in the northern and eastern portions of the subject lands, which forms part of ESPA 25; and One small pond/wetland is located in the southwest corner of the property. Surface water from most of the site (5.3 hectares) generally flows east and southeast across the site towards Idelwood Creek and eventually to a culvert that crosses Fairway Road. However, a small portion of the site (1.7 hectares) drains to the wetland in the southwest corner of the property. In terms of groundwater, the EIS states the following (page 4.2): “Groundwater level measurements indicated that local groundwater flow at the site is predominantly towards the wetland (south-east direction) from areas of topographic highs. Vertical hydraulic gradients within the wetland and creek area indicate recharging with the exception of one location which exhibited minimal discharging function.” The stormwater management strategy for the subject lands recommends the development of a stormwater management facility adjacent to the creek in the southeastern corner of the site. The facility will be equipped with a cooling trench to ensure that water is cooled before it leaves the site. The pond would discharge flows to an existing culvert and eventually to Idlewood Creek across Fairway Road. In addition, the consultants note that soils on-site are not conducive to infiltration and recommend that the water balance across the site be maintained by infiltration structures on a lot-bylot basis to the extent feasible. In summary, the subcommittee finds the stormwater management approach acceptable and recommends that, prior to site plan approval, the owner submit a detailed stormwater management plan to the satisfaction of the City of Kitchener and the GRCA. In addition, any wells not needed for ongoing monitoring should be decommissioned pursuant to applicable regulations. 5. Monitoring Program The conceptual environmental monitoring strategy for the proposed development is presented in Section 8.6 of the EIS and the subcommittee finds it acceptable. The 1639422 Page 9 of 14 18 18 May 27, 2014 Report: EEAC-14-004 program includes standard during-development monitoring procedures, such as inspection of sediment controls and tree protection measures. Further, post-construction performance monitoring will include terrestrial, stormwater and ground water monitoring. In summary, the subcommittee recommends that, prior to site plan approval, the owner submit a detailed monitoring plan for ESPA 25, the Core Environmental Feature and adjoining stormwater management facility on the subject lands to the satisfaction of the City of Kitchener and the GRCA in consultation with the Region. 6. Stewardship Plan Recommended stewardship/management measures have been included in the proposed Detailed Vegetation Plan in Appendix G of the EIS. The plan includes preserving 65 of 163 Eastern Cottonwoods (40%) within the woodland in addition to forest edge management measures. While the recommended management measures are acceptable, the subcommittee would like to make the following additional recommendations for consideration by the City during the site plan approval process: - That the owner consider dedicating through consent the portion of ESPA 25, the Core Environmental Feature and associated buffers areas on the subject lands to the City of Kitchener in order to consolidate the ESPA under municipal ownership and stewardship. - That the owner submit a detailed stewardship management plan to the City of Kitchener for the portion of ESPA 25 and the Core Environmental Feature within the subject lands including but not limited to removal and/or control of invasive species and retention of Virginia Stickseed, only if these natural areas are not dedicated to the City of Kitchener. The invasive Phragmites noted at the southern edge of the CUW1 community should be removed and disposed of in an ecologically appropriate manner to prevent its re-colonization elsewhere. - That the owner develop a brochure and other information tools for new residents which provides information about the natural heritage features contiguous to the site along with advice about how they can be good stewards of these areas, and that the brochure be to the satisfaction of the City of Kitchener, Ministry of Natural Resources and Grand River Conservation Authority. - That, that prior to site plan approval, the owner remove debris/furniture that the subcommittee observed within the cedar woodland on the subject lands, - That the stone fence along the eastern property boundary be retained, or, if necessary, re-located to provide wildlife habitat adjacent to Idlewood Creek, to the satisfaction of the City of Kitchener. Area Municipal Consultation/Coordination: The report will be shared with staff from the City of Kitchener and the Grand River Conservation Authority. 1639422 Page 10 of 14 19 19 May 27, 2014 Report: EEAC-14-004 Corporate Strategic Plan: The review of the scoped EIS for the subject application will help achieve the strategic objective to preserve sensitive natural areas.

Background The Ecological and Environmental Advisory Committee has had a long involvement with the Southeast Galt area. Beginning in mid-1997, a sub-committee worked with staff to evaluate the woodlands and wetlands along Moffat Creek which had earlier been investigated in the Moffat Creek Watershed Plan (1992-96). The sub-committee advised staff that the natural features along the creek corridor fulfilled sufficient criteria to warrant designation as a new E.S.P.A. (Report PC-EEAC-SC-97-012, dated October 28, 1997). A sub-committee also participated in the review of a Class Environmental Assessment for a road crossing of Moffat Creek (Reports PC-EEAC-SC-98-002, dated January 27, 1998, PC-EEAC-SC-98-007, dated March 31, 1998, and PC-EEAC-SC-98018, dated October 27, 1998). E.E.A.C. also provided advice on the Southeast Galt Community Servicing Study Class Environmental Assessment with respect to the stormwater management system, the sanitary trunk sewer, and watermains (Report PCEEAC-SC-99-004, dated April 27, 1999). Subsequently the committee reviewed a Plan of Subdivision for the lands north of the creek corridor (Report, PC-EEAC-SC-03-008, dated November 25, 2003). On May 29, 2007, E.E.A.C. approved terms of reference for a scoped Environmental Impact Statement for a proposed Plan of Subdivision on two large properties in Southeast Galt south of the Moffat Creek corridor. As per Report EEAC-07-007, dated May 29, 2007, the terms of reference were scoped to address the following: a. b. c. d. e. f. g. h. i. 1639039 confirmation of an ecologically and topographically appropriate boundary of the proposed Moffat Creek ESPA on the subject lands; the delineation and design of suitable buffers and/or setbacks from the proposed ESPA and the PSW on the subject lands; the ecological significance and role of the subject lands within larger landscape and particularly with regard to the proposed Moffat Creek ESPA and associated PSWs and how this will be affected by the proposed development; maintaining and/or enhancing natural linkages between major natural heritage features on adjacent properties as well as between the subject area and the rest of the proposed Moffat Creek ESPA; completion of a bio-physical survey of the property and environs and identification of any Regionally significant plant and animal species present; maintaining the quantitative and qualitative aspects of the hydrological and hydrogeological regimes sustaining the PSW on the subject properties and the rest of the proposed Moffat Creek ESPA; methods for preventing sedimentation from the proposed development areas into the PSW and the proposed Moffat Creek ESPA; the management of the trees/hedgerows along the boundaries of the subject properties and adjacent parcels and the forest /ESPA edge adjacent to the development area; and proposed stewardship options for the ESPA and buffer areas on the subject property; Page 4 of 16 27 27 May 27, 2014 2. Report: EEAC-14-005 Draft Plan of Subdivision 30T-13013 Regional staff has now received a draft Plan of Subdivision for a portion of the lands addressed in Report EEAC-07-007 located immediately south and east of the creek corridor in what is known as Neighbourhood 2. They will be accessed by the creek crossing approved in 1998 (Wesley Boulevard) and by the up-graded former Bibby farm lane which runs north from Dundas Street across a Provincially Significant marsh (the proposed Faith Street). Due to attrition since 2007, the sub-committee has been reconstituted. We have reviewed the following documents: Draft Plan of Subdivision, Bos Development (IBI Group, August 2013) Scoped Environmental Impact Study, John Bos Property (Dougan & Associates, September 2013) Stormwater Management Report, Bosdale Subdivision, City of Cambridge (IBI Group, September 16, 2013) Functional Servicing Report, Bosdale Subdivision (IBI Group, September 16, 2013) Hydrogeology Study, Residential Subdivision Site (Parcel 1), Dundas Street South, Cambridge, Ontario (Naylor Engineering Associates, December 2008) Supplementary Hydrogeology Investigation Report, 1261-1265 Dundas Street South, Cambridge, Ontario (LVM, August 30, 2013) In addition, the sub-committee and Regional staff (C. Gosselin, S Rafalski-Misch) met on site with Jim Dougan (Dougan & Associates), Andy Kroess (IBI Group), Paul Puopolo (Polocorp Inc.) and the owners John and Gerald Bos on the morning of April 25, 2014. The site visit had been postponed for several weeks due to the very cold winter weather and deep snow covering the site. After our preliminary review of the supporting studies, the sub-committee forwarded some comments and questions to the consultants in anticipation of the site visit. Following the site visit, the sub-committee and staff sent additional comments. The responses to these questions and our review of the studies have informed this report. The structure of the report will generally follow the items in the 2007 terms of reference. 2.1 Confirmation of an ecologically and topographically appropriate boundary and buffers of the Moffat Creek E.S.P.A. on the subject lands Figure 3 in the scoped E.I.S. illustrates the woodlands and wetlands comprising the Moffat Creek Core Environmental Feature. This includes what was recommended in 1997 as the Moffat Creek E.S.P.A. as well as an area of Provincially Significant Wetland which was excluded from the E.S.P.A. at that time because the former swamp and cattail marsh had been degraded by tile-draining in 1991 and had become overrun with Reed Canary Grass and Phragmites. The E.S.P.A. boundary in the vicinity of the proposed stormwater management facility shown on Figure 3 in the E.I.S. does not appear to match the Regional Core Environmental Feature layer shown on Figure 1 which is based on mapping in the Regional Official Plan (R.O.P.). In addition, the proposed boundary on Figure 3 does not appear to be consistent with E.E.A.C.’s interpretation of the boundary which was completed in 1997 (Report PC-EEAC-SC-97-012). The consultants have informed us 1639039 Page 5 of 16 28 28 May 27, 2014 Report: EEAC-14-005 that this area of shrubby meadow was cleared in 2010 so that corn could be planted on the tableland areas at the top of the valley slope. The mapping in Figure 1 represents an interpretation of the Region’s high level Official Plan mapping, and Figure 3 is the flagged boundary based on field review of existing conditions with Regional staff on September 1, 2011. Some of the area will be utilised for the stormwater management facility and the proposed restoration area. It is recommended that the E.S.P.A. boundary in this locality be interpreted to coincide with the western boundary of the stormwater management block. For the most part, the boundary around the Core Environmental Feature on the subject property is relatively well-defined due to ongoing agricultural cultivation on the adjoining fields. A ten metre buffer has been delineated from the dripline and a 30 metre buffer from the wetland within the Core Environmental Feature. The greater of the two buffers forms the limit of proposed development. The original terms of reference were adopted in 2007, well before the approval of the new R.O.P. which contains a policy requiring a minimum ten metre buffer around Core Environmental Features. The sub-committee is generally satisfied with the buffer as delineated, but has noted an encroachment into the 30 metre wetland buffer east and west of proposed Faith Street. We have reviewed the consultants’ justification that part of this buffer area is essentially a manicured lawn associated with the existing heritage home. It is further proposed to construct a retaining wall which is expected to help to control access and encroachment into the wetland and direct surface drainage back into the wetland feature to maintain the water balance. As this area is Provincially Significant Wetland and not part of the Moffat Creek E.S.P.A., it is recommended that the matter be referred to the G.R.C.A. and City for resolution. As the wetland is considered a Core Environmental Feature in the R.O.P., a minimum buffer of ten metres is required. 2.2 Ecological context and maintaining and/or enhancing natural linkages between the subject area and the rest of the Moffat Creek E.S.P.A. The Bos property is located within a larger landscape context of a large linear E.S.P.A. and Provincially Significant Wetland complex. It is important to ensure that the ecological integrity of that landscape is not unduly fragmented by new development. As articulated by the predecessor of this sub-committee in 1998, the proposed road crossing over Moffat Creek is a potential threat to ecological connectivity along the Moffat Creek corridor. 2.2.1 Moffat Creek crossing The preliminary information provided to the G.R.C.A. for the proposed culvert crossing was also circulated to the sub-committee. The proposed culvert is not what we normally think of as a culvert (i.e., pipe). A single-cell open-bottom culvert structure is proposed in the form of a concrete arch 14.6 metres wide by 3.0 metres high at its apex. It will have the capacity to convey the Regional Storm event with minimal impacts on the floodline elevation. The consultants advise that the culvert dimensions are expected to be wide enough to contain the main channel of Moffat Creek along with some adjacent bed and bank during low-flow conditions. Under normal flow conditions, it is expected that dry terrestrial benches can be incorporated to facilitate the movement of terrestrial wildlife throughout most of the year. While it may differ to some extent from what was 1639039 Page 6 of 16 29 29 May 27, 2014 Report: EEAC-14-005 considered in 1998, the sub-committee is of the opinion that the crossing structure will be sufficiently large to allow the passage of deer along the creek corridor. Given the amount of fill required to construct the crossing, there would seem to be opportunities to create dry eco-passages in the restoration areas either side of the creek to allow smaller animals to pass safely beneath the road. The sub-committee requests that all required details of the crossing, including dimensions, materials, design specifications, construction staging, temporary flow bypass, erosions and sediment control, fluvial geomorphology design, etc., be provided to the Region as well as to the City and G.R.C.A. at the detailed design stage. 2.2.2 Moffat Creek floodplain enhancement area In addition to the Core Environmental Feature, the floodplain of Moffat Creek extends well beyond the buffers in the western part of the property on either side of the proposed Wesley Boulevard crossing. This will not be developed except to construct part of that road. It is further proposed to create wetland and upland habitat in the floodplain either side of Moffat Creek in the vicinity of the creek crossing. The subcommittee strongly supports this concept in that it can be expected to support the corridor function as the lands on either side are converted to urban uses. We recommend that a detailed design and planting plan for the wetland compensation/ restoration areas in the floodplain either side of Moffat Creek or along the periphery of the marsh south of the site be submitted for approval to the Region, City, and G.R.C.A., and that plantings consist of locally-appropriate indigenous species, consistent with ROP policy 7.I.12. In addition, proposed landscape and planting plans for buffer areas will require review by Regional staff as a condition of final approval. Proposed plantings should be locallyappropriate native species as listed in the Listing of Trees and Shrubs Native to the Regional Municipality of Waterloo (1993), in accordance with ROP Policies 7.I.12 and 7.I.13. It is expected that such plans would include the type/amount, location and monitoring of all plantings. 2.3 Bio-physical survey of the property The scoped E.I.S. contains considerable detail about the vegetation communities on and in proximity to the subject property. Several plant species not previously recorded for the Moffat Creek E.S.P.A. have been noted. Nine species of Regionally significant breeding birds were also noted. The sub-committee requested further detail on Species at Risk on the site. Dougan staff has informed the sub-committee that salamander and snake surveys were conducted at MNR request in 2007 and 2011. They will contact MNR again to ensure that Species at Risk are adequately addressed in light of the recent additions and potential additions to the listings. 2.4 Maintaining the hydrological and hydrogeological regimes The Bos property is surrounded on three sides by the Moffat Creek Provincially Significant Wetland which comprises both wooded riparian swamp and open marsh 1639039 Page 7 of 16 30 30 May 27, 2014 Report: EEAC-14-005 communities which are sustained by different hydrological and hydrogeological regimes. The sub-committee is concerned that inappropriate stormwater management practices could adversely affect hydrology or cause erosion and sedimentation into the wetlands. If groundwater contributions to the wetlands are reduced, localized conversion from a moist to fresh condition may result in a long-term vegetation composition shift in the lowland Green Ash forest (Vegetation units 5.2, 6.1). Conversely, added surface or groundwater inputs could contribute to waterlogging the soils in the swamp forest along the creek and cause significant die-off of trees. From our discussions at the site meeting, it appears that the area occupied by the marsh (Units 7.2, 8.1, and 8.2) was once drier than it is at present, and that some alteration of local hydrology has occurred. Measures to avoid such changes are considered in the preliminary engineering and stormwater management design. The sub-committee notes that the hydrogeology report mentions groundwater monitoring in 2007-08 and 2013. This seems rather sporadic. We feel that groundwater monitoring from a representative sample of wet and dry years is necessary to inform the design of the stormwater management system and it component parts. 2.4.1 Enhancement of the marsh ecosystem The large open marsh habitat along the southern frontage of the property complements the wooded swamp wetlands along Moffat Creek. Marshes are not particularly common in Waterloo Region, and the sub-committee supports the conservation of the area as marsh rather than attempting to restore it back to the swamp forest that it is reported to have been in the past. Nevertheless, we view with concern the establishment of beds of Phragmites within the marsh. Ensuring a sufficient depth of water within the marsh either side of the future Faith Street (i.e., the existing farm lane) may suppress the Phragmites and Reed Canary Grass and favour re-colonisation of the area by native cattails (Typha spp.) The sub-committee requested that this be discussed in the context of the stormwater management plan as well as the design of the future Faith Street crossing of the marsh. The sub-committee would like to initiate a discussion as to whether it may be feasible and desirable to alter the hydrology of the marsh to enhance native wetland vegetation either by altering the quantity or distribution of surface or groundwater inputs, or by adjusting flows through the culvert beneath the proposed Faith Street. Phragmites removal was not considered as part of the E.I.S. The consultants have advised the sub-committee that they will consider options for the design of the future Faith Street and stormwater management facility that may have some potential to reduce the further spread of Phragmites. It is understood that high water levels could facilitate Typha re-colonisation, deter Phragmites, or possibly both. This could potentially be achieved by diverting more surface run off to the marsh or alternately by manipulating the water level in the eastern section of the marsh by raising the invert elevation of the proposed culvert. Any such options would have to be evaluated in the light of G.R.C.A. wetland policies. The subcommittee supports the recommendations in Section 7.2.3.1 which recommends consideration for the main drainage culvert to also accommodate wildlife movement, in addition to equalization culverts and wildlife directional curtains. Accommodation of wildlife movement or prevention of animal-vehicle conflicts will need 1639039 Page 8 of 16 31 31 May 27, 2014 Report: EEAC-14-005 to be balanced against managing the hydrological regime in this area. 2.4.2 Surface hydrology The stormwater management report shows that the central part of the site is an internally draining catchment. The peripheral areas of the subject property drain toward Moffat Creek to the west and southwest and to the marsh to the south which contains a tributary of Moffat Creek. The proposed post-development pattern directs most of the stormwater to a stormwater management facility beside Moffat Creek south of the proposed creek crossing. It is proposed to reduce the catchment draining directly to the upper or eastern part of the marsh from 4.212 hectares to 1.237. Maintaining the water balance of the marsh wetland is required. Nevertheless, it is also important to maintain the distribution of surface water flows to the marsh in light of the fact that Faith Street appears to act like a weir across the marsh. In this regard, the sub-committee wishes to ensure that the upper or eastern portion of the marsh is not starved of surface and groundwater inputs. The consultants have replied that maintaining the water balance of the wetland east of the future Faith Street has been one of the focal concerns of the stormwater management design. They are working to ensure that the future urban catchment routes sufficient surface water to the wetland east of the future Faith Street. It is noted that the surface catchment area for this wetland encompasses lands east of the Bos property and other areas south of Dundas Street. The Bos lands contribute approximately 4.2 ha or only 7 % of the total 58 ha drainage area. Assuming no significant reduction of surface discharge throughout the entire catchment, the consultants do not expect to see impacts to the surface hydrology of this wetland. The sub-committee is concerned about potential water quality impacts on adjacent wetlands. The stormwater management plan currently provides for an oil-and-gritseparator (OGS) for run-off from catchments 202 and 205 to the wetland. This will achieve an Enhanced Protection Level as per MOE requirements. Additional polishing for finer sediments will occur within the spreader swales. This is not able, however, to remove road salt. This issue can only be addressed by the City in its winter road maintenance practices and through salt management plans for applicable types of developments. The sub-committee had also been concerned initially about whether the proposed flow from catchment 203 would be clean in that part of this catchment (Figure 2 in stormwater management report) may include parts of driveways for single detached lots in Block 8 of the draft plan. The sub-committee has been informed that drainage from catchment 203 will consist of overflow from roof areas and rear-yard drainage which does not require additional quality treatment since it is considered clean. 2.4.3 Maintaining the groundwater regime Much of the residential area is underlain with silt till which has a low infiltration rate of 2 to 5 millimetres per hour. This is below the minimum 15 mm/hr infiltration rate recommended by the Ministry of the Environment. Nonetheless, it is proposed to 1639039 Page 9 of 16 32 32 May 27, 2014 Report: EEAC-14-005 infiltrate the first 25 mm of roof run-off in this catchment by directing it to soakaway pits. This will support recharge toward the marsh.1 Given the reported low infiltration rates (2-5 mm/hr vs. MOE recommended minimum of 15 mm/hour), the sub-committee inquired about potential alternative measures in the event the system does not work effectively. The consultants have stated that the infiltration strategy will be effective provided the infiltration facilities are designed to contain at least the first 25 mm of roof runoff, are located in areas of unsaturated soils, and are constructed with an overflow to grade. Revised preliminary water balance calculations indicate that if all subdivision roofs are directed to a lot-level infiltration facility, the existing annual infiltration rate will be exceeded. The exact locations of lotlevel infiltration facilities will be determined at the detailed design stage when additional geotechnical information becomes available. If all roof runoff cannot be infiltrated on the lots and additional infiltration is required to meet the water balance, other options can be explored including infiltration of treated road runoff, or a ‘third pipe’ system for roof runoff. In addition, options for on-site stormwater management best management practices (BMPs) such as permeable pavements can be explored for areas in the subdivision that require a Site Plan Application. The study mentions the existence of unconfined, confined and even pressurized local groundwater conditions in certain areas. The sub-committee has inquired how these conditions might affect the operation of infiltration facilities / soak-away pits. The consultants have replied that it is standard practice to install infiltration facilities only in unsaturated soils with a separation between them and the groundwater table. This is straightforward for unconfined groundwater conditions. Infiltration can also occur in soils overlying confined conditions provided those soils are not saturated as this is similar to pre-development conditions where infiltration is determined by soil type and topography. The sub-committee inquired whether research or monitoring was completed with respect to the hydroperiod in the marsh wetland. The consultants have advised that the surface flow water balance toward the wetlands is based on matching existing conditions based on an annual runoff volume. Recharge is based on matching existing conditions using active infiltration in lot-level galleries. It is suggested that continuous groundwater flow monitoring for a representative sample of wet and dry years is required to supplement the 2007-08 and 2013 monitoring. Monitoring data would be utilized to refine the proposed spreader swale designs and peak flow rates discharging to the wetland areas. 2.4.4 The stormwater management facility Proposed landscape and planting plans for the stormwater management area will also require review by Regional staff as a condition of final approval. Proposed plantings should be locally-appropriate native species as listed in the Listing of Trees and Shrubs Native to the Regional Municipality of Waterloo (1993), in accordance with ROP Policies 7.I.12 and 7.I.13. The stormwater management facility will be constructed in the first phase of the project, and immediately planted and stabilized so that it will function properly. Throughout site 1. Stormwater Management Report, p. 5-6. 1639039 Page 10 of 16 33 33 May 27, 2014 Report: EEAC-14-005 development, it will be monitored. In addition, temporary sedimentation ponds will be located throughout the development since the stormwater management pond will not serve this function. The consultants will provide further details in the final stormwater management plan. Monitoring and warranty inspection for plantings associated with the stormwater management facility will also be outlined during detailed design. Typically, monitoring activities continue until 90% build-out of a subdivision (as opposed to five years after development is initiated or 75% build-out as proposed in the EIS). The consultants are proposing to consider the monitoring requirements of all approval agencies to inform the monitoring plan. 2.5 Erosion and sedimentation control Development activities always have the potential to generate sediment and runoff into low-lying areas. Given the relatively steep slopes from the proposed development area down to the Moffat Creek wetlands, effective erosion and sedimentation control will be critical at all phases of development on this property. Table 8 of the E.I.S. lists a number of instances where clearing and grubbing are proposed. Some of these have the potential to affect the Moffat Creek E.S.P.A.: Areas of cultural thicket north and south of the marsh will be removed A swath of the Green Ash deciduous swamp will be cleared to construct the previously-approved road crossing of Moffat Creek The Bibby farm lane across the marsh will be widened and upgraded to become the proposed Faith Street The cultural meadow adjacent to the creek corridor will be removed to accommodate the stormwater management facility We recommend that detailed erosion and sedimentation plans for each of these areas be submitted to the Region along with the City and G.R.C.A. While each of these activities has the potential for sedimentation, the construction of the Wesley Boulevard crossing of Moffat Creek is of particular concern to the sub-committee, as it was to our predecessor sub-committee in 1998. 2.6 Management of the trees/hedgerows along the boundaries Since the Moffat Creek corridor is largely defined by forest/woodland features, the management of trees within the Moffat Creek E.S.P.A. will be a significant environmental management issue over time. 2.6.1 Woodlands in Moffat Creek E.S.P.A. A significant proportion of the site abuts treed areas, either E.S.P.A. woodlands or hedgerows. Although the woodlands will receive appropriate buffers from the proposed new development, the sub-committee sees a need for some additional care. For example, there is evidence of damage from the December 22, 2013 ice storm along the edge of the woodland. The sub-committee is of the opinion that the damaged trees should be tended before the E.S.P.A. is dedicated to a public agency. There is also evidence of refuse dumping by previous owners along the woodland edges which 1639039 Page 11 of 16 34 34 May 27, 2014 Report: EEAC-14-005 should be removed prior to conveyance. The Green Ash swamp community along the Moffat Creek corridor appears to be relatively healthy, but given the advance of Emerald Ash Borer, and the disturbance that will be caused by the construction of the Wesley Boulevard crossing, its long-term prospects may be in question. We recommend that before it is conveyed, that it be examined for evidence of Emerald Ash Borer mortality, and that, if it is the case, that a woodland management plan be developed. The presence of numerous ash trees along the creek corridor may warrant longer term monitoring by the City forestry staff in coming years. 2.6.2 Hedgerows The hedgerows throughout the southeast Cambridge area were identified in the Moffat Creek Watershed Study as providing a number of functions, ecological and aesthetic, and must therefore be taken into account and managed accordingly. The hedgerows form a network of small fields. Many of them contain stone piles created by previous farmers as they cultivated these stony fields. Some hedgerows on the subject property cannot be retained, but the sub-committee notes that Hedgerow 7 which frames the eastern boundary of the subject property and the City of Cambridge property to the north will remain to link the Provincially Significant Wetland to the south to a woodland adjoining the Moffat Creek corridor to the north. Nevertheless, the sub-committee notes that in the event Wesley Boulevard is extended to the east to service future development applications, there could be impacts to this hedgerow in particular and landscape connectivity in general. The consultants have stated that Impacts to connectivity posed by a future road connection would need to be addressed as part of a future E.I.S. in support of the development of neighbouring lands. They add that preliminary grading information suggests that a dry culvert may be feasible to allow movement by smaller terrestrial wildlife. 2.7 Proposed stewardship options for the E.S.P.A. and buffers The Moffat Creek E.S.P.A. and Provincially Significant Wetland on the subject property are part of a much larger natural system in southeast Cambridge. It is anticipated that as the open agricultural lands are developed, many of the natural areas will be dedicated to the City or some other public agency. The sub-committee wishes to make some recommendations with respect to areas or features on the subject property that may warrant special stewardship measures. 2.7.1 Delineation of the Moffat Creek Environmentally Sensitive Policy Area Given the impacts of adjoining residential development on natural areas, it is recommended that fencing be installed along rear lot lines where they abut the Moffat Creek E.S.P.A. or Provincially Significant Wetland to limit encroachments and unauthorised trail creation. Signage should be affixed to the fencing to inform adjacent homeowners and the general public that the area is ecologically sensitive. In addition, it is recommended that consideration be given to installing interpretive or educational signage at appropriate locations along the E.S.P.A. boundary. 1639039 Page 12 of 16 35 35 May 27, 2014 Report: EEAC-14-005 2.7.2 Trails As the extensive Moffat Creek valley provides an opportunity for trail development within southeast Cambridge, the sub-committee anticipates that a potential multipurpose trail will be developed by the City of Cambridge to tie into the proposed community centre planned for the north side of Wesley Boulevard. A well-designed trail system can guide the public safely through natural areas and help minimise encroachments and inappropriate uses. At this time, the consultants have advised that it is being considered in consultation with City staff. The sub-committee recommends that a trails plan for the area be developed preferably before residents move into the area in order to minimise negative impacts to the natural features. It is anticipated that the buffers around the E.S.P.A. may provide suitable opportunities for trails. 2.7.3 Artificial Lighting In recent years, it has come to be understood that artificial lighting can have disruptive effects on the physiology and behaviour of native plants and animals in natural areas. It is therefore becoming standard practice to design outdoor lighting on structures and along roads so that it is directed away from natural areas. It is recommended that lighting along the proposed Wesley Boulevard creek crossing, the upgraded Faith Street crossing of the marsh habitat, and also outdoor lighting required for the multiple residential properties on proposed Blocks 2, 9, and 10 be designed and placed so as not to shine into the adjoining natural areas. 2.7.4 Homeowner Information As has been recommended for other significant new residential developments, the subcommittee also recommends that the owners, in consultation with the City, G.R.C.A. and Region develop an informational brochure for future residents of the area to help them become better informed neighbours of a significant natural area. Area Municipal Consultation/Coordination: The report will be shared with staff from the City of Cambridge and the Grand River Conservation Authority. Corporate Strategic Plan: The review of the scoped EIS for the subject application will help achieve the strategic objective to preserve sensitive natural areas. Financial Implications: The usual fee for the review of a scoped EIS has been received. Other Department Consultations/Concurrence: Other aspects of this application are being reviewed by Transportation and Water Services staff. 1639039 Page 13 of 16 36 36 May 27, 2014 Report: EEAC-14-005 Attachments Figure 1 Subject Lands in Relation to Core Environmental Features Figure 2 Proposed Development Plan and Buffers to Core Environmental Features Respectfully submitted, Eduardo Cejudo Jared Ehgoetz Allison Featherstone Greg Michalenko Claudette Millar Bosdale Lands Sub-committee 1639039 Page 14 of 16 37 37 May 27, 2014 Figure 1 1639039 Report: EEAC-14-005 Subject Lands in Relation to Core Environmental Features Page 15 of 16 38 38 May 27, 2014 Figure 2 1639039 Report: EEAC-14-005 Proposed Development Plan and Buffers to Core Environmental Features Page 16 of 16 39 39 Active EEAC Sub-Committees Application Members Date Struck Status Gibney Regional Forest Operating and Management Plan Holcim Cedar Creek & Alps Pits AD LE AF, CM CP AW Feb 25/14 Awaiting suitable conditions for site visit WC AD GM Dec 17/13 Cambridge Aggregates Pit, 1830 Wrigley, North Dumfries WC, AD, LC,GM Aug 13/13 Granval Industrial Subdivision, Bishop & CanAmera, Cambridge WRDSB Property, Lackner & Fairway, Kitchener Cambridge Golf Club GM, CP, RD, TC Aug 13/13 Awaiting submission of scoped E.I.S.
