Written by GovTribe AI · Aug 24, 2026

This is a line drawing and technical specification document prepared by the Los Angeles County Metropolitan Transportation Authority (LA Metro) for cathodic protection system work on the Passenger Line A infrastructure, including multiple metro maintenance and bus divisions throughout Los Angeles County. The project encompasses corrosion control installations and maintenance across Division 11 (Long Beach facility at 4382 E 208th St) and Division 21 (Los Angeles facility at 1800 Baker Street), along with coordination across additional division locations including Divisions 2, 3, 4, 5, 7, 8, 9, 10, 15, and 18. The work involves installing new anodes, test stations, electrical isolation equipment, and reference electrodes at various yard areas within these divisions. Specific installation requirements are documented for individual test stations, with actions including clearing electrical shorts, installing new anodes (typically in pairs), installing electrical isolation kits, and replacing existing shunts. The project drawings indicate revision date of October 30, 2024, and are designed by S. Singh with in-charge engineer L. Pederson and checker E. Johnson.

The technical specifications detail installation of 48-pound magnesium alloy anodes with high-potential specifications, insulating flange kits, dielectric unions, and terminal board equipment. Work must comply with National Association of Corrosion Engineers (NACE) standards and California Code of Regulations Title Eight requirements. Contractors are required to call Underground Service Alert (USA) 811 at least 48 hours prior to work initiation, verify all utility locations through potholing, obtain required CalOSHA permits for excavations exceeding five feet in depth, and properly dispose of excavated materials. The project is partially financed through a grant from the U.S. Department of Transportation Federal Transit Administration (FTA) under the Federal Transit Act of 1964, as amended, with additional funding from Los Angeles County and State of California taxes. Contract number PS46172000 is referenced, with engineering services provided by a firm located at 23309 La Palma Ave, Yorba Linda, California 92887.
