Mr. Robert Silverstein, Esq. 0 0 <br />Review Of The Recirculated DEIR And FEIR For The San Lorenzo Sewer Lift Station Project <br />January 12, 2012 <br />Page 16 of 18 <br />Exhibit 1 is a photocopy of a part of Sheet 4 of 49 of the plans for the proposed <br />pump station. (Figure 2 -11 of the RDEIR). it has been marked up to show what <br />the superior submersible pump station alternative would look like. <br />There would be three submersible pumps in the existing 8 -foot diameter wet well. <br />The new facilities would include a valve vault in the sidewalk with a hatch cover. <br />Work on the valves thus would not have to be done in the street. Both the 19605 <br />and the 1989 pump stations had similar access hatches in the sidewalk. <br />A submersible pump station is not only environmentally superior to the Project, it <br />is economically superior. The estimated cost of a submersible pump station is <br />presented in Exhibit J. The total estimated cost is $748,000. This is less than a <br />quarter of the estimated cost of the proposed pump station. <br />Construction has just ended on the Secline Pump Station for the North Tahoe <br />Public Utility District. I was the lead design engineer on this project. In this <br />project a new circular wet well was placed in an existing rectangular wet well, <br />four submersible pumps were installed in the new wet well, a valve vault and <br />piping were installed to connect the new pumps to the existing force main, and <br />an underground pump station was abandoned. This is similar to a submersible <br />pump station that could be placed in South Bristol Street. The cost of the <br />Secline project was $750,000, which confirms that the cost estimate in Exhibit J <br />is reasonable. <br />Not only is the submersible pump station alternative about four times less costly <br />than the proposed project, but it also can be done in only a fraction of the time. <br />In the Secline project, the contractor was on site only five weeks. That, in turn, <br />means that environmental impacts of the proposed project would be mitigated or <br />avoided, including but not limited to traffic, pedestrian safety, and noise. The <br />submersible pump station alternative is clearly a potentially feasible alternative. <br />it should have been fully disclosed and analyzed, preferably as part of a <br />recirculated RDEIR, so that the public, other public agencies, and decision <br />makers have a full and fair opportunity to review and comment on it. <br />55A -165 <br />
