RECOMMENDATION(S):

APPROVE the Alhambra Valley Road and Bear Creek Road Intersection Safety and Sideshow Deterrence Project (Project), Briones Valley area. [County Project No. 0662-6U4203, DCD-CP# 18 - 29] (Districts I, V).


DETERMINE the Project is a California Environmental Quality Act (CEQA), Class 1(c) Categorical Exemption, pursuant to Article 19, Section 15301 of the CEQA Guidelines, and

RECOMMENDATION(S): (CONT'D)

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

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

FISCAL IMPACT:

Estimated Project cost: $41,000, 100% Local Road Funds.

BACKGROUND:

The purpose of this Project is to install and evaluate the effectiveness of a road feature to deter illegal sideshow activities (spinning circles and other illegal vehicular stunts) at the intersection of Alhambra Valley Road and Bear Creek Road. The community has voiced concerns about the sideshows. In response, District I, Supervisor Gioia’s Office has directed Contra Costa County Public Works to determine measures to prevent these illegal activities.

The Project consists of installing a series of 6-inch and/or 8-inch raised ceramic domes at the four approaches to the intersection. The ceramic domes will be strategically placed along the centerline striping and in the shoulder areas. The intent of the raised features is to provide a visual, auditory, and sensory deterrence, while minimizing the impact to most road users who follow the vehicle code. The Project will test if raised ceramic domes have the intended deterrent effect on sideshow activities.

CONSEQUENCE OF NEGATIVE ACTION:

Delay in approving the project may result in a delay of design and construction of a project designed to enhance public safety.
