The Community

Patterson is located in California's Central Valley, on the western edge of Stanislaus County bordering the Diablo Mountain range and I-5. It is home to 25,000 people. As of the last census, 65% of the population is Hispanic, with 25% White. It is a recognized disadvantaged community per CalEnviroScreen. Over the past several decades Patterson has seen much growth due to proximity to the Bay Area. The local economy has expanded from agriculture to include a number of large distribution warehouse centers (Amazon, Kohls, Granger, etc), among other businesses. 

The Context

Del Puerto Canyon is located just to the west of Patterson at the eastern edge of the Diablo Range.  The Del Puerto Canyon Reservoir Project, which calls for a main dam, saddle dams, and flooding several miles of the lower canyon by the I-5 Patterson exit, was formally introduced to the community of Patterson in the summer of 2019 by the Del Puerto Water District and the Water Exchange Contractors ("Partners"). By the time public comment was due regarding the draft Environmental Impact Review (dEIR) no community outreach had been made in Spanish and two of three meetings were held during working hours. Patterson city leadership remained silent on the issue. 

After pressure from Save Del Puerto Canyon, ("SDPC"), the Partners met with city leaders during a special meeting in February. A "FAQ" sheet was also provided. Although these measures were in the right vein, SDPC notes inaccuracies and glaring omissions in the information provided to the community. 

The project is not a "done deal". There are several steps prior to the final authorization of this project, and we intend to continue opposition.
