There are four common forms used to manage floodplain development:
- The Floodplain Development Permit
- The “No-Rise” Certificate
- The Elevation Certificate
- The Floodproofing Certificate
- This sample Floodplain Development Permit was developed by the State and can be used “as is” or modified to fit the community’s permit process. Regardless, some type of permit MUST be issued for ALL development in the floodplain. Floodplain Development Permit Form
- An Engineering “No-Rise” Certificate is required for all proposed development in the regulatory floodway, and must be obtained by the community before the floodplain development permit may be issued. “No-Rise” Certificate Form
- The National Flood Insurance Program (NFIP) Elevation Certificate (EC)is an NFIP administrative tool that is used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to determine the proper insurance premium rate, or to support a request for a Letter of Map Amendment (LOMA). Elevation Certificate Form
- The National Flood Insurance Program (NFIP) Floodproofing Certificate is the form used to certify a floodproofing design for non-residential buildings. This permitting acts as an alternative to elevating the building to or above the Base Flood Elevation (BFE). Floodproofing Certificate Form
Letter of Map Change (LOMC)
Individuals wanting to remove structures or parcels from the SFHA need to complete the appropriate MT (mitigation) package form. They are:
Letter of Map Revision (LOMR)
LOMR is FEMA's modification to an effective Flood Insurance Rate Map (FIRM).
How to Create a FIRMette
FIRMettes are an official copy of a portion of the FIRM panel and are considered to be a legal document for NFIP purposes. This is not true of FIRM copies reproduced using an office photocopier. A FIRMette is created online by visiting FEMA’s Map Service Center at: www.msc.fema.gov.
If it is visually apparent that a property or structure is not in the SFHA, then a Letter of Map Amendment – Out as Shown (LOMA-OAS) is an option. The LOMA-OAS will state that the property or building is correctly shown outside the SFHA.
FEMA Model Floodplain Ordinances
The State of Missouri Floodplain Management Section has developed a variety of sample floodplain management ordinances for use by communities. The ordinance your community should use will depend on the type of maps prepared by the Federal Emergency Management Agency (FEMA) for your community, the types of flood zones shown on those maps, and the level of development that exists or could occur in floodplain areas.
We recommend that you contact SEMA Floodplain Management Staff for assistance prior to adopting a floodplain ordinance. Each community is unique, and the generic ordinances included here should be tailored to each community. Also note that the SEMA Floodplain Management Staff must approve new floodplain ordinances prior to their adoption in order to verify that minimum state and federal standards are met and ensure community eligibility for the National Flood Insurance Program.
