The Cave Buttes Dam is an earth-fill flood control structure, complemented by a system of three earthen dikes, that impounds stormwater runoff from Cave Creek Wash. Constructed by the U.S. Army Corps of Engineers, the dam and dike system has provided flood protection for downstream properties in the Valley of the Sun since 1980.
The Flood Control District of Maricopa County has initiated design work for modifications to Cave Buttes Dam under a consultant contract with AECOM. While this dam has no Arizona Department of Water Resources (ADWR) dam safety deficiencies, the District intends to implement dam safety improvements to the existing Cave Buttes Dam.
These modifications will consist of two major features. The first planned improvement (Phase I) will be a drainage tunnel gated outlet and channel, which will decrease the time it takes for the water collected behind the dam to drain. The second planned improvement (Phase II) will be a seepage collection system to control potential seepage through the dam embankment and foundation.
There is no plan at this time to hold public meetings. For additional information contact the project manager listed above.
Phase I currently in design. CMAR pre-construction contract has been awarded to Coffman/SSC Joint Venture. Construction contract timing for Phase I is targeted for District Fiscal Year 2020.
