Document Description
Note: Reference SCH# 2006061140 The project proposes to reconstruct the existing Trampas Canyon Dam and Reservoir from its current use as a retention facility for tailings from the sand mining operation to a reservoir for storage of 5,000 acre-feet of recycled water. Both FEIR 584 and FEIR 589 address the anticipated development in the Project study area; therefore, an addendum to these FEIRs was prepared to analyze the potential differences between the impacts evaluated in FEIR 584 and FEIR 589 and those that would be associated with the development of the Trampas Canyon Dam and Reservoir Project. SMWD determined that none of the triggers that require a new environmental document exist.
