Report
Summary
The Tres Rios Wetlands were constructed as the final treatment for the 91st Avenue Wastewater Treatment Plant (WWTP) effluent. In addition to enhancing the effluent water quality, other benefits resulting from creation of the wetlands include rehabilitation of riparian habitat in the Salt River, and mitigation of flood damage to the adjacent community. During its conception phase, the Tres Rios Wetlands was originally planned to include public recreational and environmental education components.
These components were designed by Tetra Tech, Inc. and its subconsultants. Tetra Tech Inc.'s design contract was with the U.S. Army Corps of Engineers (USACE) and reached 95 percent completion. The plans were not completed because the USACE was unable to fund the planned 50 percent federal match to the City of Phoenix funds.
The Water Services Department is now seeking continuation of the project using the USACE's 95 percent design documents of the recreational facilities as completed by Tetra Tech, Inc. to develop an updated set of scaled-back construction documents with the recreational elements as selected by the City of Phoenix. The USACE has granted Tetra Tech, Inc. approval to use the 95 percent design documents in the preparation of final design documents for the City of Phoenix.
Tetra Tech, Inc.'s CA&I services will include, but are not limited to: project administration services, engineering services during construction, inspection services and other CA&I related services as required during construction.
