FLOOD RISK MANAGEMENT

F8 Tree planting for water attenuation In the next 5 years EWCC, Public Realm, LUPT

F9 Develop demonstration sites to show how to combine SuDS/flood attenuation systems with existing land uses

In the next 5 years

F10 Protect and conserve floodplains, wetlands, rivers and watercourses subject to flooding

# of trees planted

EWCC # of demonstration sites developed

Update: A landscaping plan has been developed for the Poddle Flood Alleviation Scheme in conjunction with SDCC Public Realm. A similar plan will be prepared for the Whitechurch Stream FAS if planning permission is approved. Tree planting schemes with pits for water attenuation have been completed on St. Joseph’s Road.

Update: South Dublin County Council has developed a number of demonstration sites to show how to combine SuDS and flood attenuation into existing land use. Examples include Integrated Constructed Wetlands at Griffeen and Dodder Valley, Permeable paving at Kiltipper Car park and Lucan Demesne. Green Roofs on Community Centres and Sports Pavilions and a Swale at Tymon Park.

In the next 5 years EWCC, LUPT Map of vulnerable areas and species’ habitats

Update: A Strategic Flood Risk Assessment and Hydrological Assessment was completed by Roughan O’Donovan to support the County Development Plan 2022-2028. Included in the Risk Assessment is a review of riparian zones with definitions, mapping and objectives are included within the written statement. The policy requires hydro morphological assessments where proposed development lands are wholly or partly within riparian corridors. A strategy is being developed for the sequential removal of culverts along watercourse routes and allowing adjacent land areas to flood water while minimising the risk of flooding to properties. The project is being carried out in cooperation with neighbouring LAs to ensure that the removal of restricting structures is done in an appropriate sequence.

F11 Integrated constructed wetlands for water attenuation and purification

In the next 5 years EWCC, LUPT # of wetlands created

Update: Integrated Constructed Wetlands currently in development as part of the Life project and the Flood Alleviation Schemes will also demonstrate how to combine nature and biodiversity with existing land use. A contractor was appointed in 2022, construction of the project is underway. ICW at Griffeen park and one on the Dodder are complete, third ICW to be completed by November 2022.
