RECOMMENDATION(S): (CONT'D)

3. AUTHORIZE the Public Works Director, or designee, to solicit bids to be received on or about March 10, 2015 and issue bid addenda, as needed, for clarification of the bid documents, provided the involved changes do not significantly increase the construction cost estimate.

4. DIRECT the Clerk of the Board to publish, at least 14 calendar days before the bid opening date, the Notice to Contractors in accordance with Public Contract Code Section 22037, inviting bids for this project.

5. DIRECT the Public Works Director, or designee, to send notices by email or fax and by U.S. Mail to the construction trade journals specified in Public Contract Code Section 22036 at least 15 calendar days before the

bid opening.

FISCAL IMPACT:

63% Environmental Protection Agency grant funds and 37% Stormwater Utility Area 17 Assessments.

BACKGROUND:

The purpose of the project is to participate in a pilot project to divert storm water to a sanitary district treatment plant to determine the feasibility of treating storm water at a wastewater treatment plant before it is discharged into a receiving water body. The project will divert storm water from the existing North Richmond Pump Station to a West County Wastewater District sewer main on Gertrude Avenue. The diversion will be conducted on a temporary basis. Inside the existing pump station, two new pumps will be installed (currently estimated at 250 gallons/minute capacity) into the wet well of the existing pump station, automated level sensors will be installed to operate the new pumps, and a new circuit breaker and control panel will be installed. Installation of the new pumps will also help rehabilitate the pump station which is in need of repair.

Plans and specifications for the project have been prepared for the Public Works Department by LCA Architects and filed with the Clerk of the Board by the Public Works Director. The construction cost estimate is $345,000 and the general prevailing wage rates are on file with the Clerk of the Board of Supervisors and will be the minimum rates paid on this project.

CONSEQUENCE OF NEGATIVE ACTION:

If the project is not approved, the County and Cities in the County will not meet the requirements of their stormwater permit issued by the Regional Water Quality Control Board. In addition, the existing pump station will continue to deteriorate and will ultimately be unable to protect the community from flooding.

CHILDREN'S IMPACT STATEMENT:

Not applicable.
