FROM: Doug Bellomo, Director
Risk Analysis Division
 
SUBJECT: Procedure Memorandum No. 53
Guidance for Notification and Mapping of Existing
Provisionally Accredited Levee Designations
 

EFFECTIVE DATE: Effective April 24, 2009, for all current,
expiring, and Future Provisionally Accredited Levee Designations

Background: To clarify the guidance for the evaluation and mapping of levee systems provided in Appendix H of Guidelines and Specifications for Flood Hazard Mapping Partners, the Department of Homeland Security’s (DHS), Federal Emergency Management Agency (FEMA), issued Procedure Memorandum No. 43 (PM 43) on September 25, 2006. PM 43 introduced the concept of the Provisionally Accredited Levee (PAL) system designation and established a reasonable timeframe (24 months) for a community or levee system owner to supply data and documentation demonstrating that a levee system owner to supply data and documentation demonstrating that a levee system meets the requirements of the National Flood Insurance Program (NFIP) regulations cited in the Code of Federal Regulations (CFR) at Title 44, Chapter 1, Section 65.10 (44 CFR Section 65.10). FEMA also implemented certain timeframes (12 months) where communities and/or levee system owners are to submit progress reports during the 24-month PAL data and documentation submittal period. To address subsequent issues and provide further clarification of requirements, FEMA issued a revised version of PM 43 on March 16, 2007. On May 12, 2008, FEMA issued PM 45 to provide updated guidance on the notes that will appear on DFIRM panels on which levee systems and levee-impacted areas are shown.

Issue: As the 24-month deadline approaches for communities and/or levee system owners to submit 44 CFR Section 65.10-compliant data and documentation for the PAL systems, FEMA recognized that a plan for mapping levee-impacted areas after the PAL period expiration date

needed to be developed in association with a public outreach and awareness strategy for these areas. The plan needs to cover both accredited levee systems and de-accredited levee systems. In developing the plan, FEMA will continue to consider stakeholders’ concerns that communities and levee system owners are confronted with serious challenges in providing 44 CFR Section 65.10-compliant data and documentation.
