Phase: Floodplain Delineation

The Flood Control District of Maricopa County (District) is conducting the Luke Watershed Phase 2 Floodplain Delineation Study to update floodplains for several washes in the upper portion of the Luke Wash Watershed. This project will revise 30 linear miles of approximate floodplains to detailed floodplains without floodways.

The study area is located in an unincorporated area of western Maricopa County and is generally bounded on the south by Indian School Road and on the north by the Central Arizona Project Canal and the west by 363rd Avenue and on the east by 335th Avenue.

Once the study is complete, impacted property owners will be invited to review its results. The study results will then be submitted to the Federal Emergency Management Agency (FEMA) for review and approval and eventually will be incorporated onto the Flood Insurance Rate Maps (FIRMs) for the area. It typically takes approximately 6 months to a year for FEMA to approve a study. Incorporation onto the FIRMs can take between 1 and 3 years after FEMA approval. In the interim, the study information will be used as “best available data” until the FIRMs are updated.


The study is currently under review by FEMA.
