Signed Community Acknowledgement forms are required when a LOMR-F or CLOMR-F application is submitted to revise a community’s FIRM or Flood Insurance Study (FIS).

Actions resulting in LOMRs generally require local floodplain development permits.

A signed Community Acknowledgement Form indicates to FEMA that:

• All necessary permits were obtained
• Applicant is in compliance with local and NFIP regulations
• Fill does not result in a floodway encroachment
• Endangered Species Act compliance (CLOMR-F)
• The community is aware of actions that can potentially impact floodplains
• The LOMR does not undermine the authority of the community
• The development is reasonably safe from flooding

Resource: For more information on the definition of “reasonably safe from flooding,” refer to guidance in Ensuring that Structures Built on Fill In or Near Special Flood Hazard Areas are Reasonably Safe From Flooding, Technical Bulletin 10 available at https://www.fema.gov/media-library/assets/documents/3522.
