RECOMMENDATION(S):

APPROVE the Morgan Territory Road Bridges 4.30 & 4.40 Scour Repair Project (Project) and AUTHORIZE the Public Works Director, or designee, to advertise the Project, Clayton area. [County Project No. 0662-6U4145, DCD-CP# 15-30] (District III)


DETERMINE the Project is a California Environmental Quality Act (CEQA), Class 1(c) Categorical Exemption, pursuant to Article 19, Section 15301(c) 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 is funded 100% Local Road Funds.

BACKGROUND:

The purpose of this project is to repair scour damage and bank erosion at two bridges located on Morgan Territory Road. Bridges 4.30 and 4.40 are similar structures that cross Marsh Creek and are located approximately 200 feet apart from each other. The project consists of installing rip rap (rock) on embankment slopes, placing a reinforced concrete slab in the channel below each bridge, filling voids in the boulder abutments with mortar, removal of trees where stability has been undermined due to erosion, repairing and replacing existing bridge railings with timber posts and guardrail system barriers, and installation of guardrail at the bridge approaches. These improvements will strengthen the bridge abutments and extend the service life of the existing bridges.

CONSEQUENCE OF NEGATIVE ACTION:

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