The project is funded by local Road Funds (100%).
In 2003, Jonas & Associates, Inc. completed a Phase I and Phase II Environmental Site Assessment for a 60 foot wide strip of land owned by Union Pacific Railroad Company (UPRR) parallel to Norman Avenue and Port Chicago Highway between Sussex Street and Warwick Street (Property) and identified the presence of polynuclear aromatic hydrocarbons and arsenic on the Property.
In February 2010, Nichols Consulting Engineers, Chtd (Nichols) completed a Phase II Supplemental Site Assessment that conducted additional testing and provided specific recommendations for mitigation of the hazardous materials identified. This report identified the construction of a pedestrian path along the former railroad track alignment as a suitable containment remedy.
The Clyde Pedestrian Path (Project) included the construction of a bicycle-pedestrian trail in the unincorporated community of Clyde. The path reflects the recommendations outlined in Nichols’ report and serves as a cap to known contaminants found on the property, providing containment of hazardous soils.
On June 22, 2010, the Board of Supervisors approved the Purchase and Sale Agreement and Grant Deed for the Property from UPRR for the Project.
On November 2, 2010, the Board of Supervisors adopted the Mitigated Negative Declaration and Mitigation and Monitoring Reporting Plan in compliance with the California Environmental Quality Act (CEQA) and authorized advertisement of the Project.
On March 1, 2011, the Board of Supervisors approved the plans, specifications, and design for the Project, Project No. 4660-6X4114-10, and awarded the construction contract for the Project. On December 13, 2011, the Board of Supervisors adopted Resolution No. 2011/493 accepting as complete the contracted work for the Project.
On November 1, 2011, the Board of Supervisors approved the Voluntary Cleanup Agreement, dated November 30, 2011, between the County and the California Department of Toxic Substances Control (DTSC), in an amount not to exceed $7,397, to provide oversight activities for the Project. A Preliminary Endangerment Assessment and Operations and Maintenance Plan for the Project, both dated May 31, 2012, were prepared by Nichols. Upon review of the Project, DTSC requested that a Covenant to Restrict Use of Property and Environmental Restriction (Covenant) be recorded on the Property to ensure full protection of the environment and human health.
On June 26, 2012, DTSC issued a no further action (NFA) letter for the Project, requiring annual reports and five year summary reports be submitted for review and approval, as long as contamination is in place. Annual reports are estimated at $2,958 for DTSC review and five year summary reports are estimated at $6,984 for DTSC review. For the purposes of estimation, the life of the Project is assumed to be 25 years. Remaining oversight activities in connection with preparation of the Covenant are estimated at $6,874, for a total fund increase of $122,603, as detailed in the attached cost estimate tables. In accordance with the Voluntary Cleanup Agreement, the fund increase will provide reimbursement to DTSC for ongoing oversight, as required by DTSC.
The project will not fulfill the requirements of the Voluntary Cleanup Agreement executed with DTSC.
