Buckeye Flood Retarding Structure No.1 was designed and built by the Soil Conservation Service (now the Natural Resources Conservation Service, or NRCS) between 1973 and 1975. The dam is located along the southern slopes of the White Tank Mountains and parallels the north side of Interstate 10 for about 7.1 miles from just west of State Route 85 to the Hassayampa River. The dam is operated and maintained by the Flood Control District of Maricopa County and is regulated by the Arizona Department of Water Resources, or ADWR.
The District, in conjunction with the NRCS, is in the process of rehabilitating Buckeye FRS No.1 to extend its useful life and ensure it continues to protect downstream property owners from a 100-year flooding event.
This project includes: raising the dam crest 2.5 to 3 feet at the eastern end of the FRS; reinforcing the auxiliary spillway with grade control and bank protection constructed with soil-cement and rip-rap; installing an engineered central filter (a zone of sand material placed in the dam to provide a safety measure from potential cracking of the embankment); installing a concrete riser for the principal spillway; constructing a closure structure (a one-way concrete box culvert) at the east end; constructing new ramps and resurfacing existing roads with gravel for maintenance; and restoring aesthetics and landscape.
The design and construction of the project has been divided into phases. Phase 1 is 2.3 miles long west of Johnson Road, Phase 2A is 4.8 miles long beginning east of Johnson Road, and the remaining eastern-most section is phase 2B.
Phase 2A construction began in September with the Contractor Mobilizing. Phase 2B design will be completed in 2016 with construction expected in 2016-2017, pending available funding.
