Report Title: APPROVE the Morgan Territory Road Bridges 5.0 and 5.2 Replacement Project and take related actions under CEQA
RECOMMENDATIONS:
APPROVE the Morgan Territory Road Bridges 5.0 and 5.2 Replacement Project (Project) and
AUTHORIZE the Public Works Director, or designee, to advertise the Project, Clayton area. [County Project No. WO4160, DCD-CP# 23-08] (Districts II, III, IV).
DETERMINE the Project is a California Environmental Quality Act (CEQA), Class 2 Categorical Exemption, pursuant to Article 19, Section 15301(c), 15301(d), 15301(f), and 15302(c) of the CEQA Statue and Guidelines, and
DIRECT the Director of Department of Conservation and Development (DCD), or designee, to file a Notice of Exemption (NOE) with the County Clerk, and
AUTHORIZE the Public Works Director, or designee, to arrange for payment of a $25 fee to DCD for processing, and a $50 fee to the County Clerk for filing the NOE.
FISCAL IMPACT:
Estimated Project cost: $5,500,000. 100% Local Road Funds.
BACKGROUND:
The purpose of the project is to improve public safety and emergency vehicle access by replacing two existing bridges on Morgan Territory Road over Marsh Creek located at postmiles 5.0 and 5.2. Both bridges are constructed of timber decks on rubble abutments with significant scour at the abutments and retaining walls. Both replacement bridges will be clear span, one lane with shoulders supported by reinforced concrete pile abutments and wingwalls; concrete barrier rails and metal guard railings at the bridge approaches will be installed, and adjacent drainage improvements. The profile grade of the roadway and bridges will be raised, and the lengths of both bridges will increase to meet hydraulic requirements for the 100-year storm event and restore the natural width of the channel under the bridges. Riprap will be placed in the creek at both bridge locations and at four (4) outfall locations within the project area to prevent future scour and continued degradation of the creek.
CONSEQUENCE OF NEGATIVE ACTION:
The bridges would continue to deteriorate, posing risks to the safety and structural integrity of the bridges.
