The Public Comment Period for the Calaveras Dam Replacement Project DEIR has been extended to December 21, 2009.

“The San Francisco Public Utilities Commission has requested, and received, an extension to the public comment period for the Draft EIR for the Calaveras Dam Replacement Project from the San Francisco Planning Department. This is in response to requests received from other public agencies and the general public and the need to accommodate an additional public hearing for the project. ”  (source: SFPUC website)

EBCNPS is concerned that the EIR fails to properly report impacts to vegetation that will be inundated.  Since these vegetation impacts are not clearly defined, the mitigation measures are equally vague.  The failure of the analysis to be appropriately specific on impacts and mitigations brings into question the adequacy of this document.  Additionally, all habitat mitigations are materializing slowly, “to be completed within 5 years of the completion of the project”.  We believe all mitigations should be complete before construction is initiated.

Additionally, the reservoir expansion project will impact known populations of two CNPS 1B plants: Mt. Diablo helianthella and Most-beautiful jewelflower.  Additionally, fish resources and silverspot calippee habitat will be taken in this expansion project.  The below Figure 4.4.4 shows some of the impacted resources (reproduced from the EIR).
