Project Contact: Richard Harris
Region: W
District: 4 - Clint L. Hickman
Phase: Floodplain Delineation
Description:

The Flood Control District of Maricopa County (District) is conducting the Palo Verde West Area Floodplain Delineation Study to update several  Zone A (approximate) floodplains. The update will establish Zone AE floodplains with Base Flood Elevations (BFE’s) using improved mapping and updated hydrologic information.

The study is located within the western part of Maricopa County, and is generally bound by West Heatherbrae Avenue on the north, Roeser Road on the south, 395th Avenue on the east, and 443rd Avenue on the west.

The study is complete. Impacted property owners have been notified and are able to review the results online. The study results have been submitted to the Federal Emergency Management Agency (FEMA) for review and approval and will eventually be incorporated onto the Flood Insurance Rate Maps (FIRMs) for the area. FIRMS are special maps that show flood hazards for an area. They are produced as part of the County’s participation with the National Flood Insurance Program (NFIP). It typically takes approximately 6 months to a year for FEMA to approve a study. Incorporation onto the FIRMs can take up to 1 additional year after FEMA approval. In the interim, the study information will be used as best available data for regulation purposes.

Status:

The study has been submitted to FEMA for review and approval.
