RECOMMENDATION(S):

DETERMINE that the Vasco Road Overlay project is a California Environmental Quality Act (CEQA) Class 1C Categorical Exemption, and


DIRECT the Director of Community Development to file a Notice of Exemption with the County Clerk, and

RECOMMENDATION(S): (CONT'D)

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

APPROVE the project, and AUTHORIZE the Public Works Director, or designee, to advertise the project.

FISCAL IMPACT:

This project will be funded with $2.6 million from the Federal Economic Stimulus Bill and a 10% Local Road Funds match.

BACKGROUND:

The purpose of the project is to improve the pavement condition of Vasco Road by providing an asphalt concrete overlay on Vasco Road between the Alameda County Line and Frisk Creek Bridge. The project will grind and overlay Vasco Road between the Alameda County Line and Frisk Creek Bridge (7.4 miles). The project does not include any pavement widening and all work will be contained within the existing road pavement. The project will include base and pavement failure repairs in some locations requiring excavation of the existing road pavement to the bottom of the existing base layer. The excavations will not exceed the bottom of the existing roadway base section and therefore, native soil will not be disturbed. A consistent 0.2-foot-deep grinding of the existing roadway pavement from edge of traveled way to edge of traveled way will be followed by installation of pavement reinforcement fabric and a 0.2-foot-thick asphalt concrete overlay. The new pavement surface elevations will match the existing roadway surface elevations. Traffic control devices such as thermoplastic striping, rumble strips, and delineators will be applied in the center line and on both sides of the traveled way; the existing paved shoulders will be applied with fog sealant. A construction staging area approximately 4,000 square feet in size has been identified approximately 0.6 mile north of the Alameda County line in a previously disturbed area, directly adjacent to the southbound lanes. At least one lane in each direction will be maintained throughout construction. Emergency vehicle access will be allowed at all times.

This project will not result in the removal of any scenic resource.
