Floodway Development
Any project in a floodway must be reviewed to determine if the project will increase flood heights. An engineering analysis must be conducted before a permit can be issued. The community's permit file must have a record of the results of this analysis, which can be in the form of a No-rise Certification. This No-rise Certification must be supported by technical data and signed by a registered professional engineer. The supporting technical data should be based on the standard step-backwater computer model used to develop the 100-year floodway shown on the Flood Insurance Rate Map (FIRM) or Flood Boundary and Floodway Map (FBFM).

FLOOD ZONE A 

  1. THE FOUNDATION,  THE UTILITIES, AC, THE WELLHEAD AND PUMP MUST BE ELEVATED 2’ ABOVE THE HIGHEST ADJACENT GRADE.
  2. ELEVATION CERTIFICATE BY THE OWNER OR AGENT.
  3. IN ADDITION FOR MOBILE HOMES
  • LOWEST FLOOR JOIST OF MOBILE HOME MUST BE ELEVATED 2 FEET ABOVE HIGHEST ADJACENT GRADE
  • ENGINEERED TIE DOWN FOR MOBILE HOME IF BLOCKS ARE IN THE BFE. (MOBILE HOMES WILL ALWAYS NEED ENGINEERED TIE DOWN UNLESS THE PROPERTY IS BUILT UP.)
  • FLOOD VENTS IN THE SKIRTING.

                                                                     OR

  1.  BUILD UP PROPERTY AT LEAST 2’ ABOVE THE HIGHEST ADJACENT GRADE.

 FLOOD ZONE AE

  1. THE FOUNDATION,  THE UTILITIES, AC, THE WELLHEAD AND PUMP MUST BE ELEVATED ABOVE THE ESTABLISHED BASE FLOOD ELEVATION.
  2. ELEVATION CERTIFICATE BY THE OWNER OR AGENT.
  3. IN ADDITION FOR MOBILE HOMES
    • LOWEST FLOOR JOIST OF MOBILE HOME MUST BE ELEVATED ABOVE THE ESTABLISHED BASE FLOOD ELEVATION.
    • ENGINEERED TIE DOWN FOR MOBILE HOME IF BLOCKS ARE IN THE BFE. (MOBILE HOMES WILL ALWAYS NEED ENGINEERED TIE DOWN UNLESS THE PROPERTY IS BUILT UP.)
    • FLOOD VENTS IN THE SKIRTING.

                                                   OR

  1. BUILD UP PROPERTY ABOVE THE BASE FLOOD ELEVATION
