Honorable Board of Supervisors

Neil R. Cullen, Director of Public Works

SUBJECT:

Coyote Point Marina 2003 Maintenance Dredging Project

Recommendation

Adopt a resolution authorizing an increase in the "not to exceed" amount for the Coyote Point Marina 2003 Maintenance Dredging Project (Dredging Project) from $1,081,000 to $1,131,000 - an increase of $50,000 - to provide for additional dredging in the Marina.

Previous Board Action

Adopted Resolution No. 065970 which awarded a contract for the Dredging Project to the Dutra Construction Company in an amount not to exceed $1,081,000.

Key Facts

*

The contract included a relatively high contingency ($238,000) as the Parks and Recreation Division of the Environmental Services Agency (Parks) wanted to take advantage of the favorable unit prices that we received for the work.

*

Parks has now requested that the dredging contract be increased in order to include the dredging of the boat slip areas where large boats are berthed.

*

The boat slip areas are included in our regulatory permits and Marina Funds are available to finance the cost of this additional work.

Discussion

Parks was recently approached by Marina tenants who have requested that individual boat slips also be dredged as part the current projects as some of the larger boats are "hitting bottom" at low tide. Parks evaluated the tenants' request and are recommending that the large boat slip dredging be included in the contract in addition to other areas that were originally contemplated when the Dredging Project was awarded.

The contractor has provided an estimate for this additional work that includes the mobilization of additional smaller equipment, as the boat slips are narrow, and smaller less efficient dredging equipment is necessary to complete this work. This dredging coupled with the other additional work as proposed, is estimated to increase the total project cost to approximately $1,131,000. The final cost will be based on the amount of material actually dredged.

The contractor was beginning to mobilize his forces of the project at the writing of this report. However, we are recommending that the contract be increased at this time as we anticipate the contractor being prepared to do the work relatively soon since he is proposing to work 24 hours a day seven days a week.

Vision Alignment

We believe our recommendation is consistent with the Shared Commitment to "preserve and provide people access to our natural environment" and Goal Number 15 "residents have nearby access to green space such as parks and recreational opportunities, as the dredging will allow the boating public to continue to have access to the Bay for recreational opportunities from the Coyote Point Marina.

Fiscal Impact

The "not to exceed" costs of the project, as stated in the Recommendation section of this report, will increase by $50,000 to $1,131,000 if your Board approves the proposed resolution. Funds for the work are available from the Marina Reserve Fund and there is an appropriation in the Capital Project Budget that is sufficient to cover this work.

The Director of the Environmental Services Agency and Parks Director concur in our recommendation.

There is no impact to the General Fund.

A form of resolution has been approved by County Counsel.
