Region: W
District: 5 - Steve Gallardo
Description:

The Flood Control District of Maricopa County (District) is conducting a detailed Floodplain/Floodway Delineation Study along several washes in the Rainbow Valley area.

The study will use detailed topographic mapping and technical analyses to re-evaluate the extent of floodprone areas along the study washes. The results will be a re-delineation of the floodplain boundaries, and, for some washes, an upstream extension of the floodplain and/or the addition of a floodway. This detailed study will replace the results of portions of a previous delineation study which used approximate study methods.

Status:

The study has completed and the Federal Insurance Rate Maps have been updated effective February 2014 to reflect the study results.
