Reports and Documents

Once available, public review documents and reports related to the Sunnyvale East and West Channels Flood Protection Project will either be listed on the right under the "Related Information" box or posted below.

Pursuant to the California Environmental Quality Act, the District, as the lead agency for the Project, has prepared a Draft Environmental Impact Report (DEIR) to evaluate environmental impacts of the proposed Project. The DEIR identified potentially significant environmental impacts associated with aesthetics, air quality, biological resources, cultural resources, geology/soils, greenhouse gas emissions, hazardous materials, hydrology/water resources, noise and vibration, land use, public utilities, recreation, and traffic. The majority of impacts were determined to be less than significant after the implementation of mitigation measures proposed for the Project. Construction impacts related to violation of applicable air quality and noise/vibration standards were determined to be significant and unavoidable even after implementation of air quality and vibration mitigation measures.

The Draft EIR and all related documents can be reviewed on any District business day between the hours of 8 a.m. and 5 p.m., at the District’s headquarters building, located at 5700 Almaden Expressway, San Jose, CA 95118. In addition, electronic PDF versions of the documents are available for download below.

The public comment period on the Draft EIR closes at 5 p.m. on December 15, 2013. Comments should be submitted via mail or electronically, by 5 p.m. to:

  • By mail to:  Tiffany Hernandez, Santa Clara Valley Water District, 5750 Almaden Expressway, San Jose, CA  95118
  • or, email
