Preparing Your Business: Flood Protection Checklist
Determine if your building is located in a Special Flood Hazard Area.
Find out the base flood elevation (BFE) for your property.
Consult your community’s records or your property survey for the elevation of your building’s lowest floor. If the community records and the property survey do not indicate the elevation of the lowest floor, you will need to hire a licensed surveyor to determine it.
If the lowest floor is below the BFE, consider the following retrofit options:
Relocation out of the floodplain provides the greatest protection from future flooding. A building that is structurally sound can be relocated although this is an expensive option. If the structure has had repetitive losses, it may be eligible for assistance from FEMA.
Elevation of an existing structure provides the owner an opportunity to retrofit the structure by raising it above the anticipated base flood elevation level. It may be elevated by using fill, solid extended foundation walls, columns or piles. The technique used will depend largely on the flood, site and building characteristics, as well as cost.
Flood proofing involves preventing floodwaters from entering a structure (dry flood proofing) or allowing floodwaters to enter a structure and flow through reducing the impact on the structure walls (only recommended for basements). Dry flood proofing involves completely sealing the exterior walls of the structure to prevent entry of floodwaters. Dry flood proofing provides an excellent vehicle for owners of existing flood-prone non-residential structures to bring them into compliance with the standards of the National Flood Insurance Program. It tends to be affordable and effective and should be considered if your facility is subject to flooding.
Identify and repair all leaks and cracks to windows and doors, roof, foundation and exterior walls, plumbing, ventilation, heating and air conditioning systems.
Prevent water intrusion through good inspection and maintenance programs.
