Western San Bernardino Distribution System Infrastructure Protection Program

Western San Bernardino Distribution System Infrastructure Protection Program

The proposed program consists of a comprehensive program to design and construct projects addressing surface infrastructure repair and protection needs, while simultaneously implementing a plan for conducting routine operations and maintenance (O&M) activities in the Western San Bernardino County Operating Region in order to ensure continued water supply reliability. The scope of the program does not include projects related to the subsurface infrastructure (i.e., pipelines). There are two components within the proposed program: Capital Investment Plan (CIP) projects and O&M activities. The proposed CIP projects generally consist of repair, upgrade, and/or relocation of existing structures, or the installation of structures to address access or infrastructure problems that threaten system reliability. Types of CIP projects fall into three categories: patrol road improvements and paving, engineered erosion control, and slope stabilization. These projects typically require design engineering and would be conducted on a one-time basis. Metropolitan’s proposed O&M activities are conducted on a regular and ongoing basis and are intended to maintain existing structures, patrol roads, and other appurtenant pipeline structures. These activities are currently ongoing within the Western San Bernardino County Operating Region; however, an O&M Manual, which is being developed as part of this program, would establish a formalized plan that would provide a systematic and scheduled approach to these maintenance activities. O&M activities are divided into two categories: routine O&M activities and single-occurrence O&M activities. Routine O&M activities are repeated, routine activities that occur and will continue to occur at regular intervals to maintain patrol roads and other infrastructure in good condition. These activities include patrol road maintenance; patrol and inspection; routine structure maintenance, repair and replacement, including maintenance/cleanout of drainage features; facility maintenance, repair, and replacement; vegetation management/maintenance; and other activities such as pipeline shutdowns/dewatering and emergency work. Single-occurrence O&M activities would typically be conducted on a one-time basis and would include repair, rehabilitation, or replacement of existing structures to support the continued operation and maintenance of existing pipelines and appurtenant pipeline structures. These O&M activities are primarily limited to installation of low water crossings, including Arizona crossings, culverts, and/or bridges to reestablish and improve access along patrol roads. Metropolitan, acting as the Lead Agency under CEQA, certified a Program Environmental Impact Report for the “Western San Bernardino County Distribution System Infrastructure Protection Program” on October 13, 2020.
