Additionally, LOMR, Best Available Data Letters issued since the previous effective FIRMs in September 30, 2005 as well as three community restudies: North Scottsdale, Lower Centennial wash, and Upper New River, will be incorporated. Maricopa County will also be completing analysis for 44 CFR 65.10 certification or Provisional Accreditation of levees and these zones will also be incorporated on the map revision.
