Conservation & Development, Public Works Finance Div., M. Cordis, PWD Maintenance Div. C. 6 To:Board of Supervisors From:Julia R. Bueren, Public Works Director/Chief Engineer Date:July 31, 2012 Contra Costa County Subject:APPROVE Winslow Street Retaining Wall Project & AUTHORIZE Public Works Director, or Designee, to advertise the project & make related CEQA findings BACKGROUND: The purpose of this project is to repair the failing wood retaining walls on the north side of Winslow Street, directly across from 219 Winslow Street in Crockett. The repair is needed to protect the roadway because the wood walls retain fill under the roadway. A guardrail end treatment will also be added to the end of the existing guardrail where currently none exists. The end treatment will be angled away from the edge of the pavement to reduce the likelihood of a head on vehicle impact to the end of the guardrail. The work will consist of removing the two existing wood retaining walls. The west wall is a 2-foot tall wood wall, and the east wall is a 5-foot tall wood and steel beam wall. The two existing wood retaining walls will be replaced with one new wood and steel beam wall in approximately the same footprint. The new wood and steel beam wall will consist of 10 piers spaced approximately 5 feet apart. The piers will consist of steel beams set in drilled and concreted 18-inch diameter holes that are 6 to 11 feet deep. The total length of the wall will be approximately 45 feet. The end treatment is approximately 36.5 feet long and will be placed at the end of the existing west wall. Additionally, a limited amount of trees and shrubs will need to be trimmed to complete the work. One existing tree stump will be removed, but no tree removal is necessary. Real Property transactions may be necessary in support of this project. At least one lane of traffic will remain open at all times during construction activities. Emergency vehicles will have access at all times. CONSEQUENCE OF NEGATIVE ACTION: Delay in approving the project will result in a delay of design and construction and may jeopardize funding.
