Floodplain ordinances l.jpg

Floodplain Ordinances

  • Model provided by MS and LA

  • Local Authority

    • Permits

    • General Standards

      • Flood loss reduction methods and practices

      • Protection of utilities and services

    • Specific Standards

      • Lowest floor elevation

      • Floodproofing nonresidential buildings

      • Manufactured Homes/ RV’s/ Subdivisions

Local Floodplain Permit Requirememts

ANY development in the mapped floodplain

requires permit review

Buildings must be protected

Residential – elevated

Non-residential – floodproofed

Minimal value – wet floodproofed

Other development activities must not

alter or divert flood waters or flood neighbors.

Permit Issuance

The process of administering & issuing…

  • The floodplain development permit is issued for everything that alters the floodplain.

  • Every development proposal must be reviewed in regard to its location.

  • What is development?
