Procedure Memorandum No. 42 - Quality Control Requirements in the DFIRM Process
This Procedure Memorandum provides Federal Emergency Management Agency (FEMA) staff, contractors, and mapping partners with guidance for seven quality control reviews to be performed during the Pre-Preliminary and Post-Preliminary Phases of the Digital Flood Insurance Rate Map (DFIRM) production process. The original memo was issued on June 20, 2007, which was later revised and re-issued on December 1, 2008. The revised PM42 only partially supersedes the original PM42, therefore, both memos are effective for their relevant sections.
