  • Using the Flood Maps as Part of the Planning Process

    These flood maps can be used to produce Flood Consequence Assessments (FCAs). It is incumbent upon the applicant to produce an FCA when seeking planning consent. All developers should contact Environment Agency Wales prior to the commencement of an FCA (see 'Useful Links and Contacts'). Climate change scenarios should also be used to support planning applications.
