Description:

The purpose of the McMicken Dam Rehabilitation Project is to provide for the overall rehabilitation of the McMicken Dam Project, and in coordination with project stakeholders and with public input, improve the function and benefits associated with the current McMicken Dam Project.

The McMicken Dam Project was constructed by the U.S Army Corps of Engineers (USACE) in 1954 and 1955 to protect Luke Air Force Base, the Litchfield Park Naval Air Facility, and agricultural activities in the area from flooding. Today, the McMicken Dam Project also provides flood protection for critical public facilities, infrastructure and properties located directly downstream, including significant portions of Surprise, El Mirage, Sun City, and unincorporated Maricopa County. The ability of the McMicken Dam Project to maintain the current level of protection in the long term for the benefit of the public in an increasingly urbanized environment is in question due to significant concerns regarding aging infrastructure, land subsidence, earth fissuring, urbanization encroachment and current dam safety standards. These dam safety issues have led the District to determine that an overall rehabilitation of the dam is required. Landscape and multi-use opportunities will also be evaluated.

Status:

The District has initiated design for the rehabilitation of McMicken Dam. AECOM Technical Services, Inc. is the engineer of record. The rehabilitation will occur in phases starting with the emergency spillway and principal outlet reconstruction and relocation (Phase 1) along with a new principal outlet channel, north dam extension and a Picacho Wash Diversion Dike and Emergency Spillway Exit Channel (Phase 2). Final design of Phase 1 is scheduled for completion in April 2019. Final design of Phase 2 is scheduled for completion in February 2020. Construction of Phase 1 is anticipated to begin once design is complete. Phase 2 construction will commence when Phase 1 is complete.
