Powerline Flood Retarding Structure (FRS) is the northern-most of a system of three flood control structures (Powerline FRS, Vineyard Road FRSĀ and Rittenhouse FRS) running parallel to the Central Arizona Project between the Baseline Avenue and Ocotillo Road alignments in Pinal County. Despite being located in Pinal County, the structures primarily provide flood protection for downstream portions of Maricopa County. Powerline FRS conveys stormwater runoff to the Powerline Floodway which outfalls at the East Maricopa Floodway. The structure is 2.5 miles in length and has a height of 26 feet, with a storage capacity of 4,194 acre-feet. The three structures combined capture stormwater from a 159-square-mile area including parts of the Superstition and Goldfield mountains. The U.S. Soil Conservation Service, now the Natural Resources Conservation Service (NRCS), was the federal sponsor. The District and the U.S. Soil Conservation Service were cost share partners on this project.
