The Section 19 investigation for Sully has identified 18 properties that were affected by surface water flooding on 23rd December 2020. The Vale of Glamorgan has already secured £149,270 funding to provide property level flood protection measures to 21 properties in Sully. Property surveys are ongoing and installation is planned within the next 6 months. Whilst this will help protect the individual properties it won’t help prevent any wider impacts due to flooding of gardens, outbuildings and roads. The Lead Local Flood Authority therefore intends to assess the viability of a community level scheme to manage the risk of surface water flooding in the area, starting with an application to Welsh Government for funding to develop an outline business case. Development of an outline business case will require more detailed modelling of the existing flood risk and potential damages as well as the assessment of options, such as flood storage areas or upgrading of existing infrastructure and associated costs. The timescales for delivery of any physical works will depend on the location and type of works as well as securing the necessary funding and consents for delivery. Subject to a successful bid to Welsh Government for Flood Defence Grant in Aid, preparation of an outline business case is expected to commence in April 2022, with an estimated completion timescale of 6 months.
A Section 19 investigation for Dinas Powys identified 98 properties that were affected by internal flooding on 23rd December 2020 and one of the key recommendations was to consider the viability of Property Flood Resilience (PFR) measures for at risk properties across Dinas Powys. Since the 2020 event the Vale of Glamorgan has developed a business case and secured Welsh Government grant in aid funding allocation of £2.5M for the installation of PFR to 181 properties. Procurement of the PFR installation contract is ongoing with award anticipated in April 2023, subject to Welsh Government funding approval, and an estimated 9 month programme of works.
