RECOMMENDATION(S):

APPROVE the Stone Valley Road Bike Lane Gap Closure Project and AUTHORIZE the Public Works Director, or designee, to advertise the project, Alamo area. County Project No.: 0662-6R4209, DCD-CP#07-91 (District II)


DETERMINE the project is a California Environmental Quality Act (CEQA), Class 2 Categorical Exemption, pursuant to Article 19, Section 15302 of the CEQA Guidelines; and

RECOMMENDATION(S): (CONT'D)

DIRECT the Director of Conservation and Development to file a Notice of Exemption with the County Clerk; and

AUTHORIZE the Public Works Director to arrange for payment of a $25 fee to Conservation and Development for processing, and a $50 fee to the County Clerk for filing the Notice of Exemption.

FISCAL IMPACT:

This project will be funded by 62% Transportation for Livable Communities Grant; 38% Alamo Area of Benefit Funds.

BACKGROUND:

The project consists of the closure of an approximately one (1) mile long gap in the bike lane between Round Valley Drive and Alamo Hills Drive. The gap closure will allow a continuous class II bike facility along the south side of Stone Valley Road. The project will widen the north and south sides of the roadway along the length of the project from one to four and a half feet, depending on the existing roadway width. The project will add striping for the bike lanes and construct one median island. The project will include replacement of the existing curbs and dikes with Portland Cement Concrete (PCC) curb, Asphalt Concrete (AC) dike and gutter. Three drainage inlets will need to be relocated to accommodate the widened bike lane. Two locations (east and west of the intersection of Justin Morgan Dr. and Stone Valley Road) along the project site may require an approximately three foot tall, 500 foot long retaining wall along the side of the road to support the adjoining slope after construction. A Rectangular Rapid Flashing Beacon (RRFB) will be constructed at the existing crosswalk of Roundhill Drive. One existing crosswalk at Alamo Hills Drive will be removed. Sidewalk along the south side of Stone Valley Drive will be constructed from Roundhill Drive to Alamo Hills Drive. In order to accommodate the bike lane, the minor reconstruction of a hardscape median (narrowing by 1 foot) may be required. In order to minimize damage to any nearby trees, any roots exposed during excavation will be cut cleanly and tree branches will be trimmed. Three ornamental trees will be removed due to the project. Real property transactions may be necessary in support of this project. At least one lane of traffic will be open at all times during construction activities and emergency services access will be provided for at all times. Utilities may need relocation as a result of the project.

CONSEQUENCE OF NEGATIVE ACTION:

Delay in approving the project may result in a delay of design, construction, and may jeopardize funding.

CHILDREN'S IMPACT STATEMENT:

Not applicable.
