SUBJECT:

Reconstruction of Portions of Princeton Avenue and Broadway - Princeton-By-The-Sea [County Project No. RL303, Project File No. E4841000]

RECOMMENDATION:

Adopt a Resolution:

1.

Adopting plans and specifications, including conformance with prevailing wage scale requirements for the reconstruction of portions of Princeton Avenue and Broadway - Princeton-By-The-Sea; and

2.

Authorizing the publication of a Notice to Contractors twice in a weekly local newspaper of general circulation published in the County; and

3.

Authorizing the Director of Public Works to call for sealed proposals to be received by Thursday, July 14, 2011 at 2:30 p.m., in the office of the Clerk of the Board of Supervisors.

BACKGROUND:

On December 15, 2009, your Board adopted Resolution No. 070583, which approved a work plan for spending Proposition 1B Transportation Funds allocated in the FY 2007-2008 Supplemental Appropriation, and must be spent by June 30, 2012. The Princeton Avenue and Broadway reconstruction project is in the approved work plan.

On December 4, 2007, your Board adopted Resolution No. 069136, which approved a two-foot road realignment on Princeton Avenue (from Broadway to Columbia Avenue) to minimize the impact to the eighteen Monterey Cypress trees in the roadway shoulder.

On October 11, 1994, your Board adopted Resolution No. 058748, which adopted minimum road standards for road policies and standards for the Mid-Coast area including the Princeton-By-The-Sea area.

DISCUSSION:

The proposed reconstruction of Princeton Avenue (between Vassar Avenue and Broadway) and Broadway (between Harvard and Princeton Avenues) to the adopted road standard was based on the results of property owner surveys in 2007. The property owners were in favor of their road being reconstructed to the adopted standard, which is two 11-foot wide travel lanes, with a 3-foot wide valley gutter on each side. The project has not been completed due to limited funding, therefore the roads have continued to degrade. The pavement condition indexes for Princeton Avenue and Broadway are 4 and 32, respectively, with 100 being the best possible pavement condition rating.

Your Board received comments and provided direction to the Department at your June 7, 2011 meeting. As a result, the Department has further evaluated the existing and proposed drainage patterns and stormwater quantity and quality within the project scope. This project, which does not change existing drainage patterns and directions of flow, calls for shaping an existing earthen swale and planting vegetation on Broadway. Columbia and Vassar Avenues currently have grass lined drainage swales. Vassar Avenue is not in the County road maintenance system. This work will increase infiltration, reduce stormwater velocities, and filtrate sediment. Additionally, the project includes grading the shoulder areas after the reconstruction work is complete, in order to improve drainage conditions and minimize stormwater ponding in parking areas. Based on the comparison of existing and proposed conditions, we believe that the completed project will provide for improved water quality, formalize the drainage system, reduce the impact to stormwater, and improve the roadway for the traveling public.

The Granada Sanitary District and Coastside County Water District have requested that specific sewer or water facility work be performed in conjunction with this project. The plans and specifications for the work have been prepared and staff is recommending that your Board authorize calling for bids for the proposed work.

County Counsel has reviewed and approved the Resolution as to form.

Approval of this action will contribute to the Shared Vision 2025 outcome of a Livable Community by improving our roads for use by the traveling public to support livable connected communities.

FISCAL IMPACT:

The estimated cost of construction is $365,000 and is proposed to be financed as follows:

Coastside County Water District*

$ 4,000

Total Estimated Cost

*The Director of Public Works is authorized to enter into agreements with special districts and utility companies for work less than $50,000 proposed to be done in conjunction with County road projects. Reimbursement for the cost of doing work for the Granada Sanitary District and the Coastside County Water District will be covered by agreements executed by the Director as authorized by your Board.

There is no impact to the General Fund.
