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 Dysart Ranch and Sage Creek Floodplain Delineation Study to update a ponding Zone AH floodplain and several Zone A floodplains in partnership with the City of Avondale. The update will account for improved infrastructure built since the effective study was completed. Most significantly, the subdivision was constructed on dirt fill material that is likely to reduce the floodplain limits.

The study is located within the City of Avondale in the western part of Maricopa County, and is generally bound by Indian School Road on the north, the Roosevelt Irrigation District (RID) Canal on the south, Dysart Road on the east, and Litchfield Road on the west. The floodplains that will be studied are located within the Dysart Ranch and Sage Creek subdivisions.

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 until the FIRMs are updated.

Status:

The study results have been submitted to FEMA for review and approval.
