Local Ownership of Floodplain Maps Through Letters of Map Change Pilot Program
Local communities have a vested interest in maintaining up-to-date floodplain maps and flood information. Through a pilot program, Storm Water Services reviews and processes Letters Of Map Change (LOMCs.) The Federal Emergency Management Agency (FEMA) has historically processed these revisions to approved floodplain maps.
However, on July 1, 2006, FEMA delegated to Charlotte-Mecklenburg Storm Water Services the authority to review and process Conditional Letters of Map Revision (CLOMRs) and Final Letters of Map Revision (LOMRs.) The pilot program applies to LOMCs for unincorporated Mecklenburg County, the City of Charlotte, and Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill, and Pineville.
In 1999, Storm Water Services contributed $2,000,000 to develop an updated Flood Insurance Study (FIS) and revised Flood Insurance Rate Maps (FIRMs) which were formally adopted by FEMA in 2004. Those FIRMs are updated by the issuances of LOMCs.
