As highlighted in the Flood Consequences Assessment, the most significant source of flooding at risk to the site is tidal from the Irish Sea. The site is protected to some extent to the north from coastal sand dunes and the embankments of the Flint-Prestatyn railway line. The mechanisms for site flooding include breach or overtopping of this protection. The Flood Warning and Evacuation Procedure will be designed to help manage residual risks from extreme events in case of a breach of flood defences, and will inform site residents of potential risks, flood emergency procedures and identify escape / evacuation routes as recommended by the Environment Agency publication ‘Flooding – Minimising the risk. (See Appendix F) This document outlines new procedures to implement, their limitations and recommendations for improvements. Additionally, plans indicating a safe exit route and flood warning notices for placement around the site have been included.

Although specific details of the proposed development of the site have not yet been fully realised, it is understood that the site will be developed for a similar enduse i.e. touring caravans and as such the Flood Warning and Evacuation Procedure has been developed on this basis. This document has been written in line with current guidance from the Environment Agency, ‘flooding- Minimising the risk’ which is included in this report (See Appendix C). The objectives of the site specific Flood Warning and Evacuation Procedure are to: Outline responsibilities placed on the site owner Know what precautions to take to safeguard everyone on site Establish a set of actions to take in the event of a food Highlight the Flood warning Codes and Signage Provide a Evacuation Route/Map Minimise the impact of flooding on the site Irish St Marys Caravan Park NORTH Mostyn Road Gronant Prestatyn Figure 2 – Site Location Plan (Source Google Maps) File Name and Path N:\0769_St Marys Park Prestatyn\Reports\R0769_02 Flood Warning & Evacuation Plan\R0769_02_ Flood Warning & Evacuation Plan.doc QAF32.1 Rev 02 Document Ref Issue No Page No R0769_02 01 1 of 1 Sanderson Watts Associates 2.0 SITE INFORMATION & FLOOD RISK SUMMARY 2.1 Existing Site Description St. Marys Caravan Park is located to the North East of Gronant village centre and approximately 3.5 km east of Prestatyn town centre. (Grid Reference SJ 09915 83507) Area denotes extents of North Site NORTH ; Mostyn Road Area denotes extents of South Site Dashed line denotes approximate location of section A-A See Figure 4 Figure 3 – Enlarged Site Plan (Source Google Maps) The site is separated into two distinct areas either side of Mostyn Road (A548) Prestatyn. For the purpose of this report these areas are referred to as ‘North Site’ and ‘South Site’. A topographical survey of the two areas is provided in Appendix A. Both areas of the site are considered vulnerable to Flooding from the Irish Sea to the north as detailed in the Flood Consequences Assessment produced by Sanderson Watts Associates (R0769_01). The North Site camping and as historically for surfaced access the east. incorporates approximately 4.8 Ha of land, and was primarily used for such consists mainly of grassed areas. The remainder of the site was used touring and static caravans and comprises of grassed areas and gravel roads, with a reception building located to the south and wooded areas to The South Site is approximately 2.5 Ha of land arranged on four levels. The site entrance level is at 7mAOD with three tiers at 11mAOD, 17mAOD and 26mAOD respectively, supported by gabion walls. The site consists of primarily grassed areas with a gravelled access road leading to the uppermost level to the south. A washroom building is located 45m south of the site entrance and a small electrical out-building is present along the northern boundary. Trees traverse the northern boundary of the site.

The south boundary of the site is approx 20m higher than levels by Mostyn Road. Therefore we would suggest the south part of the site is significantly less vulnerable to tidal flooding from the Irish Sea. 2.2 Proposed Development The site is to be re-developed with a similar end use to the existing arrangement, i.e. as a caravan park. The site will retain many of the original features and infrastructure from the existing development including the site access roads and the reception building. Development plans for the South Site are still to be confirmed. 2.3 Sources of Flooding There are several potential sources of flooding, these include; Surface water run-off from the site Fluvial flooding from several streams and a pond sited on the North Site Tidal flooding from the Irish Sea to the north There is no significant increase in impermeable area on site from the proposed development. Also the majority of the site is free draining with the roof of the reception building providing the most significant source of impermeable area. It should also be noted that the site will be closed during winter months (a time when the site is more at risk from flooding due to increased soil water saturation and groundwater levels). As such the risk of an active site flooding from surface water is therefore considered negligible. The EA have confirmed that the site will not be subject to fluvial flooding from the streams and pond located on site. It can therefore be seen that the major potential source of flooding for St. Marys Caravan Park is tidal flooding from the Irish Sea.

These defences include formal protection from coastal sand dunes and informal protection from the embankments of the Flint-Prestatyn railway line to the north (this is considered informal as future maintenance of the embankment cannot be relied on upon if the line is discontinued). It should be noted that the extents of flooding shown on the EA Flood Risk Map exclude any protection offered from sea defences. 2.5 Areas Affected by Flooding During an extreme event of tidal flooding from the Irish Sea; where the costal sand dunes could be breached, the first affected area in relation to St. Marys Caravan Park would most likely be Presthaven Sands Holiday Park. The Holiday Park lies within Flood Zone 3 on EA maps (Appendix D); the north boundary of the site projects out onto the sand dunes, and follows the coastline for approximately 1.9km. The EA maps also show these natural sand dunes have some localised defence measures. Added to this Presthaven Sands and surrounding land, including the majority of the north Site at St. Marys are described by the EA as: “areas benefiting from Defences” (See Appendix D). The Presthaven Sands Holiday Park’s south boundary runs parallel, and backs onto the FlintPrestatyn railway line. The railway also divides Presthaven Holiday Park and Greenacres caravan Park as presented in Figure 5 below. Figure 5 – Site Plan and Surrounding Area File Name and Path N:\0769_St Marys Park Prestatyn\Reports\R0769_02 Flood Warning & Evacuation Plan\R0769_02_ Flood Warning & Evacuation Plan.doc QAF32.1 Rev 02 Document Ref Issue No Page No R0769_02 01 4 of 4 Sanderson Watts Associates The land separating Presthaven Sands Holiday Park and St. Marys Caravan Park which also lies within Flood Zone 3 appears to be agricultural farmland with open drainage ditches some of which are described as main rivers on the EA Flood Maps (Appendix D); we anticipate this area may also have underground land drains that potentially run into the open ditches/rivers. One river in particular runs straight through the north site of St. Marys Caravan Park and into the pond to the East Part of the north site. 2.6 Flooding Route In the worst case event of a tidal flood, it is expected that the flow of flood water will travel upstream through the open ditches which run through the North Site of St. Marys Caravan Park. It is expected that during an extreme flood event overwhelming surge loads will be generated whereby all site infrastructure is liable to failure; resulting in burst pipes and channel overflows which will be dispersed to the localised areas. It is expected some flood water may be retained by the land drainage, however once the land is saturated, ground water levels would increase and rapidly envelop the North Site. 2.7 Flooding History The Strategic Flood Risk Assessment for Denbighshire County Council has been reviewed along with information provided by the EA. There is a history of flooding in Denbighshire which can be traced back from records to 1879. Several flood events occurred through overtopping of sea defences which caused flooding of coastal properties in Rhyl and Prestatyn. Other records indicate flood events near to major rivers in the area including the Dee, Severn, Wye and Clwyd Rivers. There is also evidence of coastal flooding near to Colwyn Bay. The SWA Flood Consequence Assessment (R0769-01) indicates that the south site lies in an area known to have flooded in the past, though the EA have no record of this occurrence.

With no mechanisms in place the site staff and visitors are unable to prepare for possible flooding and arrange and organise the site accordingly. Safe egress from the site is also compromised. 3.3 Recommendations To ensure the safety of staff and visitors on site at the St. Marys Caravan Park, the following procedures should be put in place: • The Site Manger should request receipt of ‘flood warning direct’ Automatic Voice Messaging (AVM) from the EA. • A Flood Warning Procedure to be put in place including the following actions: - A log book to be kept of all visitors to the site (this is not currently in place). The Site Manager will be responsible for notifying all staff and visitors on site flowing receipt of an AVM. - The Site Manager is to be responsible for coordinating responses to flood warnings when an AVM is received (See Section 7.0 for the EA’s flood warning codes); managing staff and visitors during the Flood Warning Procedure and ensuring safe evacuation route is known and followed. • All staff and visitors on site should be made aware of the EA Floodline telephone number and the four flood warning codes and their meaning (see Section 7.0). • According to the EA, the Local Authority/Police endeavour to give at least 2 hours warning of an impending flood – however given the sites proximity it will be a requirement that all staff and visitors will be assembled immediately upon receipt of any warning. • Training on the Flood Warning Procedure will be given to site staff at Health and Safety Briefings – staff will be made aware of the Safe Exit Route, EA Floodline, Flood Warning Notice and Flood Warning Codes. • Site induction for any staff working on site is to include awareness of the Flood Warning Procedure. • All visitors to the site are to be made aware that there is a Flood Warning Procedure and Evacuation Plan in place and where to locate it.

This route is also appropriate for vehicular exit from the site. The proposed ‘on-site’ meeting place is outside the Washroom Facility of the South Site. As indicated in Figure 6 by the Green Circle. The level outside the washroom is approximately 8mAOD and lies within in Flood Zone 1 i.e. outside the extreme event flood extent and is classed as low risk. There are available areas for car parking; and most importantly the location provides safe egress from the site outside the floodplain. Figure 6 – Flood Risk Map (Source environment-agency.gov.uk) The route outlined in Appendix B specifies a safe vehicular exit route from the north site and a suitable meeting point where a head count can be undertaken out of danger of any sudden rise in water level. The exit route and evacuation procedures have been determined based on existing site conditions. It is also considered appropriate for any future developments, unless the safe assembly point or access to the safe area is inaccessible (See section 6.0). As shown in Figure 4 (Page 3), the land rises steeply to the south of the site. In a worst case event, should the intended assembly point be affected by the flood, evacuees could retreat to these elevated areas until the emergency services arrive.

However it should be noted that codes may not always be given in sequence and in the cases of flash flooding no time for warnings may be possible. In the event of a serious flood event across the site the competent warning authority is the Environment Agency. When a flood is expected the Local Authority and local emergency services will be responsible for public care and safety. This section sets out 3 action levels and the actions associated with each phase of the flood risk as: Flood Alert Flood Warning Severe Flood Warning All Clear 7.2 Flood Alert What it means: Flooding is possible. Be prepared. When it's used: Two hours to two days in advance of flooding. What to do: Be prepared to act on your flood plan. Prepare a flood kit of essential items. Monitor local water levels and the flood forecast on the EA website. In Detail: The EA will issue a Flood Alert status when flooding is possible. This will be issued by the EA through their website and Flood Warning Direct based upon the weather and river conditions.

Be aware, be prepared, and watch out. When a Flood Alert warning is issued residents should: • Be aware of water levels and whether the river is rising or falling • Reconsider travel plans • Listen to and watch for weather and flood warnings on local radio and television stations • Contact Floodline on 0848 988 1188 • Check that a flood kit has been prepared At this stage residents should ensure that their neighbours are aware of the Flood Alert in case residents are not subscribed to Floodline Warning Direct and do not receive the alert. 7.3 Flood Warning What it means: Flooding is expected. Immediate action required. When it’s used: Half an hour to one day in advance of flooding. What to do: * Move family, pets and valuables to a safe place. * Turn off gas, electricity and water supplies if safe to do so. * Put flood protection equipment in place. In Detail: Flood Warning means – ‘Flooding of homes and businesses is expected. Act now. The flood warning alert will be issued when water levels are rising and further rain is expected – it is advised to safeguard the property and prepare to evacuate. At this stage residents should: • Contact the local emergency authorities to find out whether evacuation is considered necessary and where they are providing for evacuees • Consider what is needed if evacuation to short term accommAODation is necessary: children’s essentials (for example, milk, baby food, sterilised bottles and spoons, nappies and wipes) medication and clothing (if there is heavy rainfall you may get wet whilst evacuating).

It will be necessary to switch off utilities and secure unoccupied properties during evacuation. • Put sandbags or flood boards in place Residents must locate, water, electricity and gas supplies and switch off before evacuating. If residents are unsure of how to do this they must contact their supplier. Neighbours may be able to provide assistance as the houses within the development are generally similar and other residents may have similar problems or solutions. Residents should call the EA Floodline on 0845 988 11 88 periodically and listen to and watch for weather and flood warnings on local radio and television stations. If water levels begin to fall without reaching the properties, residents should continue to monitor the situation. Residents should stay alert and be ready to evacuate and check the EA warning code status. 7.4 Severe Flood Warning What it means: Severe flooding. Danger to life. When it's used: When flooding poses a significant threat to life. What to do: * Stay in a safe place with a means of escape. * Be ready should you need to evacuate from your home. * Co-operate with the emergency services. * Call 999 if you are in immediate danger.

There is extreme danger to life and property and people are advised to act immediately i.e. Evacuate. The Environment Agency aim to provide at least 2 hours warning between the Flood Warning alert being issued and the commencement of flooding. The EA recommend that residents should evacuate when a Flood Warning or Severe Flood Warning status is issued. If flood levels continue to rise, residents are advised to evacuate before safe access is lost. At this level driving through flood water may become hazardous and residents must evacuate beforehand. Residents should monitor the flood progression and evacuate, on foot as soon as possible. The safe access route (See Appendix B) in times of flood will be clearly marked and signposted and residents should use this route for means of evacuation rather than attempting an alternative route. Residents should be aware that parts of the evacuation route may be up to 300mm depth of flooding. Before evacuating, residents must ensure that all windows are securely closed and locked; this will provide protection against thieves and water pressure caused by flood waters. On leaving the property residents must ensure that doors, including internal doors, are securely locked and closed. At this stage the local authority, the emergency services and the Environment Agency should be managing the situation, with widespread flooding potentially over a large area, and will endeavour to provide advice on an evacuation route, shelter and assistance to evacuees. The Local Authority has a legal obligation to provide assistance to evacuees under the Homelessness Act 2002. However, residents must be aware that at times of widespread flooding local services may have difficulty providing for a large number of evacuees. In this instance residents may be advised to stay upstairs in their home by the relevant authorities. 7.5 Flood Warnings are no longer in Force What it means: No further flooding is currently expected in your area. When it's used When river or sea conditions begin to return to normal. What to do: * Be careful. Flood water may still be around for several days. * If you've been flooded, ring your insurance company as soon as possible. All clear means that flood watches or warnings are no longer in force in this area. • Keep listening to weather reports • Only return to evacuated buildings if you are told it is safe • Beware sharp objects and pollution in flood water File Name and Path N:\0769_St Marys Park Prestatyn\Reports\R0769_02 Flood Warning & Evacuation Plan\R0769_02_ Flood Warning & Evacuation Plan.doc QAF32.1 Rev 02 Document Ref Issue No Page No R0769_02 01 15 of 15 Sanderson Watts Associates Residents should contact the local authority to check that it is safe to return to their property. Residents should be aware that if floodwaters have entered the property it will need to be cleaned disinfected and repaired and fully dried out prior to reoccupation. Residents must check that the building is safe before entering the building, and if there are any doubts professional opinion should be sought. If there is any doubt that appliances may be water damaged they must be checked before switching the power or gas back on. Contact your insurance company as soon as possible to get their approval before arranging any clean-up or repairs. These codes are typically written for domestic/residential scenarios however in the event of a flood the same principles should be applied to touring caravans and static lodges. IE, switch off utilities at mains and secure windows and doors to prevent theft and water damage etc. File Name and Path N:\0769_St Marys Park Prestatyn\Reports\R0769_02 Flood Warning & Evacuation Plan\R0769_02_ Flood Warning & Evacuation Plan.doc QAF32.1 Rev 02 Document Ref Issue No Page No R0769_02 01 16 of 16 Sanderson Watts Associates 8.0 CONCLUSIONS & RECOMMENDATIONS 8.1 CONCLUSIONS This Flood Warning and Evacuation Procedure has been designed to help manage residual risks from extreme events in case of a breach of flood defences which could affect St. Marys Caravan Park, Prestatyn. These measures are designed to minimise the impact of flooding and ensure the safety of staff and visitors, not to prevent nor minimise the risk of flooding to the site. This Flood Warning and Evacuation Procedure will enable the site manager to inform site residents of potential risks, flood emergency procedures and identify escape / evacuation routes. It is apparent from acquired data that the North Site is at greater risk as it lies within Flood Zone 3 of Environment Agency Maps. Therefore, a safe evacuation assembly point has been identified outside the washroom of the South Site as this area lies out of high-risk (Flood zones 3 & 2) and site levels are higher than Mostyn Road and the North Site. The EA have confirmed that this is an appropriate muster-point. 8.2 RECOMMENDATIONS The Site Manager should register with the Environment Agency and sign up to ‘Floodline Warnings Direct’ (call Floodline on: 0845 988 1188) This is a free, 24 hour service that sends automated flood warnings by telephone, SMS text, email fax or pager. The ‘Safe Exit Route Map’ and ‘Flood Warning Notice’ posters/or similar should be made available/displayed to all people on the site, including all staff and visitors. The Site Manager should complete a ‘Business flood plan’ See Appendix G to establish Key Contacts and locations of service shut off points etc. On receipt of a Flood Warning from the relevant authorities the Site Manager should initiate the flood warning and evacuation procedures appropriate to the flood warning code given. If the Site Manager is informed of a flood warning via third party source, confirm the authenticity with the Police, Environment Agency or Local Authority prior to instigating evacuation. If the usual meeting place or the route to the usual meeting place is obstructed by any onsite activities a temporary meeting point/route should be identified and notified to all staff and visitors for the duration of any such activities.
