FLOOD RISK MANAGEMENT

F12 Develop a climate change impact GIS risk map with scenarios for the Dublin Region

In the next 5 years

EWCC GIS map developed

Update: South Dublin County is susceptible to several types of flood risk. The flood zone extent mapping were prepared and are presented in Appendix A of the SFRA report developed by ROD to support the County Development Plan 2022. The flood zone maps are primarily derived from the Eastern CFRAM and the Dodder CFRAM mapping. The maps are the most comprehensive flood maps produced for South Dublin since the introduction of the Guidelines and the Floods Directive. Flood extents for areas that are outside of the scope of the CFRAM Studies and are supplemented by fluvial mapping from the earlier OPW Preliminary Flood Risk Assessment (PFRA) Report. Additionally, pluvial flood extent mapping has been prepared for the 1% and 0.1% AEP events as derived from the PFRA study. The Flood Zone mapping is based on the best currently available data. More detailed, site specific Flood Risk Assessments may generate localised flood extents.

F13 Develop template to capture impacts, response and costs (including ecosystem services/natural capital costs) for all major climate events

In the next 5 years

EWCC Template developed and issued

Update: The CARO have developed a mobile data collection App named WIRE (Weather Impact REgister) for local authority staff to record the impacts of weather events. The data collected by the App can be accessed via an online Map Viewer and Data Dashboard with spatial analysis and reporting functionality to assist climate adaptation planning. The WIRE App was piloted in a number of local authorities including South Dublin in 2020/2021, after which upgrade work was completed with the finalised App launched in 2022. CARO are working with interested LAs to implement the system across Climate Action Teams and wider Local Authority teams. CARO are also working to link other data collection systems in use in LAs, such as MapAlerter, with the WIRE App dataset. For further information contact wire@caro.ie

F14 Update DLA urban drainage and flooding policies for current knowledge of flood risk and the latest best practice in drainage design, promoting natural flood measures as a priority

In the next 5 years EWCC, LUPT Policies updated

Update: South Dublin County Council SuDS guidance documents were published in February 2022. Householders guide was published in May 22. Training has been provided to SDCC staff March and April 2022. Workshop for developers was presented by McCloy Consultants and SDCC on 24th May 2022. Taking in Charge SuDS documents were issued in August 2022. Policies have been developed in the County Development Plan 2022-2026 on Riperian Corridors based on a hydromorphological assessment and Flood Risk Assessment.
