Progression of new schemes

• Clyde Kelvin and Irvine Schemes (Interim arrangements now operational)

• Dee, Don, Deveron and N Esk Schemes (CBA and feasibility complete)

• Coastal flood warning scheme (requests received from Dundee CC and Lord Thurso, - anticipate request from Western Isles Council)

• Stirlingshire Rivers (request received)• Extension of Irvine to Lower Irvine and Garnock?• River Nevis (SEPA proposal).

Key Facts

• Flood warning schemes implemented following requests from LA’s in response to flood events

• No consistency in flood magnitude• Variation in dissemination methods• Requests are progressed under SEPA Policy 34• Key areas of Scotland at risk have no FWS –

including coastal areas• More Strategic approach required
