Description:

Areas along the Salt River have been subject to historic debilitating floods. The District has participated in various projects since its inception to channelize sections of the Salt River and mitigate this historical flooding hazard.

This summary addresses recent channelization efforts.

The first section of the Salt River to receive channelization improvements since 1990 was the area between approximately 40th Street to the Southern Pacific Railroad Bridge near Mill Avenue in Tempe. The Arizona Department of Transportation (ADOT) was the construction lead for this section and the project was constructed in partnership with the District, ADOT, the Salt River Project and the cities of Tempe and Phoenix. Generally, the District is responsible for the operation and maintenance of all flood control facilities and the cities of Tempe and Phoenix are each responsible for maintenance of all landscaping and aesthetic features within their jurisdictions. (IGA 87051, 87052, 87053)

The Salt River between Mill Avenue and McClintock was the next section to receive channel improvements. To reduce costs, the improvements were implemented in conjunction with the construction of the SR-202L freeway. ADOT was the construction lead and a cost share partner along with the District and the City of Tempe. Tempe is responsible for the maintenance of all landscaping and aesthetic features and the District is responsible for the operation and maintenance of the flood control features. (IGA 89025, 90008, 93004)

Channelization of the Salt River between McClintock and SR-101L was also constructed in conjunction with the freeway. The project consisted of hard-bank implementation with ADOT as the construction lead. The District and the City of Tempe shared project costs for the south bank and ADOT covered all costs for the north bank. ADOT is responsible for the operation and maintenance of the roadway and all non-flood control features and the District is responsible for all flood control features of the project. (IGA 94001)

Channelization along the south bank of the Salt River from SR-101L to Country Club Drive was implemented as part of the construction of the freeway. ADOT was responsible for the construction as well as all costs and maintains all non-flood control features. In accordance with the IGA, the District is responsible for the operation and maintenance of the flood control features of the project.** Similar channelization was completed on the north bank of the Salt River from SR-101L to approximately 1800 feet west of Alma School Road. The project was completed in partnership with ADOT and the Salt River Pima-Maricopa Indian Community (SRPMIC), with SRPMIC as the project lead in accordance with the IGA. SRPMIC is responsible for the operation and maintenance of all non-flood control features and the District is responsible for all flood control features of the project. (IGA 95005, 98013)

The most recent section of the Salt River to receive channelization was the section between the I-10 Bridge and 19th Avenue in Phoenix. The project, known as Phoenix Rio Salado, was sponsored by the U.S. Army Corps of Engineers (USACE) and locally by the City of Phoenix. The project included environmental restoration as well as construction of flood control features including a low flow channel, grade control structures and related side drainage. The District was the construction lead for the flood control features and in accordance with the IGA was a cost share partner along with the City of Phoenix. A separate IGA was competed between Phoenix and USACE for the cost share of the project. The City of Phoenix is responsible for the operation and maintenance of the completed project. (IGA 98040)

All referenced channelization projects were completed between the years 1991 and 2002 and provide 100-year flood protection.

Status:

Recent channelization efforts were completed in 2002.
