Floodplain Development Permit

Floodplain Development Permit

Review of a Floodplain Development Permit is the procedure used by the City to review applications for land-disturbing activities such as grading or deposition of fill within the Special Flood Hazard Area.  The Special Flood Hazard Area is a flood-prone area adjacent to a watercourse that has a one percent chance of being inundated by floodwater in any given year.  For the purposes of the Floodplain Development Permit, the Special Flood Area is the same as the 100-year floodplain (the area likely to be subject to partial or complete inundation by floodwater during a flood anticipated to occur only once during any 100-year period).  The Special Flood Hazard Area is depicted on the City’s Flood Insurance Rate Maps on file in the offices of the Planning and Code Enforcement Department.  The purpose for the Floodplain Development Permit is to ensure that any activities occurring within the 100 year floodplain will have only a negligible impact on the floodplain’s ability to contain floodwater during the 100-year flood event.

Construction of habitable floor area within the 100-Year-Floodplain requires preparation and approval of an Elevation Certificate by a licensed engineer prior to issuance of a Building Permit.  To be approved, the Elevation Certificate must demonstrate that the lowest habitable floor area and all associated appurtenances (like water heaters, major appliances, HVAC condensers, electrical outlets, etc.) are at least two feet above the base flood elevation.  The base flood elevation is the minimum elevation (relative to sea level) that has a one percent chance of flooding during any given year.  The City’s standards require that all development be at least two feet above the base flood elevation. 

Detailed information on the City’s Flood Damage Prevention standards may be found in Chapter 12 of the City Code of Ordinances (http://online.encodeplus.com/regs/fayetteville-nc/doc-viewer.aspx#secid-29).
