Building in a Floodplain?
The County Building Department requires a survey to determineBase Flood Elevation (BFE) and additional building requirements to ensure compliance with ASCE 24-05 pertaining to Flood Resistant Design and Contstruction. A National Flood Insurance Program (NFIP) Elevation Certificate will be required at the end of the project. If you are a contractor or a homeowner and are working within the 100-year floodplain you must hire a qualified design professional to assist with surveying, design and construction, and/or the use of fill.
