BACKGROUND:
The Coyote Point Marina periodically requires maintenance dredging due to siltation of its channels and boat slips from San Francisco Bay’s tidal action. Previous maintenance dredging in 2010, 2006, and 2002 included the Marina’s main channel, most of the secondary channels used by tenants to access their boat slips, and specific boat slips. Since the completion of those dredging episodes, new siltation has occurred that is once again affecting navigation in portions of the Marina.
On June 28, 2016, your Board approved a contract with TranSystems, Inc. to provide consultant services to prepare plans and specifications and to secure permits for the Coyote Point Marina 2017 Maintenance Dredging Project (“Project”). On May 16, 2017, your Board adopted Resolution No. 075201, which adopted the Project plans and specifications, including conformance with prevailing wage scale requirements and calling for sealed bids for the above-mentioned project. The necessary agency permits for the Project have been obtained and the Project qualifies for a Categorical Exemption pursuant to the California Environmental Quality Act (CEQA) Guidelines for Implementation, which will be filed by the San Francisco Bay Regional Water Quality Control Board.
DISCUSSION:
On Wednesday, June 14, 2017, bids were accepted for this Project and subsequently referred to Public Works for checking and recommendation. The bid of:
Salt River Construction Corporation
5643 Paradise Drive, Suite 8
Corte Madera, CA 94925
at $1,169,750 was the lowest bid received for the work. The final Engineer’s Estimate was $1,175,000. A summary of the bids received is attached as Exhibit “A”.
County Counsel has reviewed and approved the resolution and agreement as to form.
Approval of this action will contribute to the Shared Vision 2025 outcome of an Environmentally Conscious Community as sediment removal through the Project will keep the Marina entry channel at sufficient depths for vessels to use and will minimize accidents from occurring.
FISCAL IMPACT:
The total estimated construction cost of construction is $1,286,750, which includes authorization for up to $117,000 in change orders as the work is bid on a unit price basis. The contingency is used to pay the contractor for any unforeseen conditions not anticipated in the construction agreement documents.
The Project has been included in the Recommended Budget for FY 2017-18 for the Coyote Point Marina Fund, which is funded by the user fees and boat slip rentals.
There is no impact on the General Fund.
