How long does it take to obtain a LOMA, LOMR, or physical map revision?
For single-building or single-lot determinations that do not involve changes to base flood elevations or floodways, a LOMA or LOMR-F generally can be issued within 4 weeks. LOMAs and LOMRs involving multiple lots or multiple buildings require up to 8 weeks to process. Times are specified from the date of receipt of all technical, scientific, or legal documentation. LOMRs involving decreases in Base Flood Elevations (BFEs) or floodways take approximately 90 days for processing. If changes in flooding conditions are extensive or if BFEs increase, a physical map revision will be required, which will take 12 months or longer.
