Reports and Documents

Pursuant to the California Environmental Quality Act, the Santa Clara Valley Water District, as the lead agency for the proposed project, prepared a Draft Environmental Impact Report and a Final Environmental Impact Report to evaluate environmental impacts of the proposed flood protection project. Below is a summary of the environmental reports and documents.

Draft Environmental Impact Report 

The Draft EIR 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. 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 was published and circulated between November 1, 2013 and December 15, 2013. The public review period was extended to February 21, 2014 to accommodate additional review time by the public agencies.
