Active Community Fund GRANT APPLICATION FORM Section D: Your funding application Community Group Tarring Flood Action Group SuDs retro solutions to surface water flooding Project Title recommendations from earlier Feasibility study. Description of issues, needs and/or initiatives Within the West Tarring Conservation Area (See attached supplementary paper -map Appendix 1) there are a number of areas that large amounts of water collects on a regular basis, and more importantly, there have been a number of occasions in the recent past (2000, 2012) when flash floods have badly affected the area, resulting in flooding of, and damage to, a number of residential and commercial properties. Tarring High Street, in the conservation area, has had several floods in recent years and old buildings at the south end of the street and at the north end of South Street / Priory Close have suffered in particular. Following discussions at a TFAG Multi-Agency Meeting, the general consensus is that the floods were caused by a number of contributing factors:- • Climate Change impacting on localised intensity of rainfall • An inability of the network of drains and gullies to cope with heavy downpour events • Blocked drains and gullies • An aging, predominantly combined, surface water and sewage system • Discharge of roof water directly on to pavements/roads • Bow-wave surges caused by uncontrolled through-traffic • The influence of the Teville Stream and its confluence with Broadwater Brook, although this factor is subject to debate. • The lack of empirical data on problem areas of pooling and flooding in the Worthing area. • The dominance of a hard landscape and the lack of any ‘natural’ means of absorbing excessive rainwater before it can develop into flooding. The TFAG has developed an action plan with WSCC and other agencies to deal with short-term and longer-term actions and strategies, which include training, community awareness and involvement, and the maintenance of our local environment on an ongoing basis. Phase one included two Operation Watershed grants results of which would inform future Operation Watershed applications and work in the area. • Jetting and CCTV investigation of combined Highways & Southern Water surface water drainage network in various road to identify any issues and ascertain if the flooding is related to a capacity issue or specific blockages = £16,2020 - Conclusion: CCTV did not identify any specific blockages so flooding issues are related to a capacity issue in the network. • Feasibility study to investigate the potential options for Sustainable Urban Drainage that would work with and supplement the existing drainage to increase capacity for surface water during times of heavy rain including Rectory Road, High Street, South Street, Glebe Road and Church Road = £38,460 - Conclusion: Feasibility study identified 2 locations and types of schemes that would provide the biggest benefit and value for money. A) Rectory Road network of Rain Section D: Your funding application Gardens B) High Street permeable paving Alongside the Operation Watershed applications, the Flood Action Group have been working with the residents, schools and businesses around how they can contribute towards reducing the risk of flooding. • Expansion and Sustainability of the new Tarring Flood Action Group and our Adopt a Drain Pilot”, we now have 90 volunteers and new members to the Core group. This group monitor highway gullies that are prone to flooding, remove debris and report any issues to Love West Sussex. • Ongoing monitoring and attention by local community members to include a public event. (promoting extension to recycling of water butts.) Video made by two members of the Adopt a drain team and a public information event at a local venue. • Working with local schools to promote what people can do in their own properties to reduce surface water flooding and assist in increasing local drainage capacity. • Completion of a community Resilience plan agreed by WSCC Fire & Rescue Service to respond to flooding emergencies. • Adoption of the green space at junction of Rectory Road and High Street to undertake planting to reduce surface water run off at this point. • Working with other Residence Associations and Community Groups to develop groups and schemes to raise awareness of what can be done to reduce the risk of flooding in an urban area. The group are working with the Borough Council Parks Team and the Emergency Planning Officer around activities to reduce flooding in the area. Attached additional supporting information: • Highways Verges and Retrofitting SUDS summary from feasibility study findings and EA data • Love West Sussex report Oct 2018 to 2020 – log of reports of highways flooding/drainage issues • Woodlea Road Community Gulley Clearance 18.01.20 Flooding of High Street Section D: Your funding application Brief description of proposed works or activity Construct a network of 3- rain gardens in the existing grass verges along the eastern side of Rectory Road. Complimented by two further rain gardens located in the western side of Rectory Road/Fairoak Triangle opposite the bus stop and school. The rain gardens will manage surface water through mimicking natural processes. Reducing the flow and peaks of stormwater (attenuation), storing water above and below ground, as well as enhancing the environment providing green space for both people and wildlife. They can also reduce discharges to the sewer network, therefore, lowering the risk of surface water and sewer flooding in higher order rainfall events. • All areas to be dug out to 1000mm and then back filled with 200mm drainage aggregate/800mm of special blend soil (50% BS3882 and 50% Horticultural sand lime free/sharp sand) Please bear in mind we are working in quantities of 5/600 Tons of specially blended soil in/out • To include 10 x drop kerbs with positioning to accommodate existing sewers. • Shingle channels included to allow water to reach the base of each section quickly • To include steppingstones to cross from the road as discussed • To include a planting scheme (as Maltravers) at 5 per metre 3L pot size with species attached to this email • All traffic management (no road closure/lights) and correspondence with authorities as such – to include closure of relevant footpaths.

Community Commitment Statement: Please provide a statement detailing; What the Group is contributing to the delivery of this project in terms of management, funding, volunteers; What the Group will contribute to further outcomes after completion of this project; What commitment the Group will make to ongoing maintenance where appropriate; How this project will bring your community closer together. The Tarring Flood Action Group is communicating with local schools, businesses, and general public through our network of supportive and active partners: Worthing Borough Council, the High Street Residents’ Association, the Neighbourhood Watch, Transition Town, and the West Worthing Baptist Church. We are pleased to report that significant interest is being expressed including the local children.
