Department of State Hospitals Metropolitan Water Tanks #1 and #2 Replacement Project

The Department of State Hospitals is undertaking a major infrastructure project at its Metropolitan State Hospital campus in Norwalk, California, to replace two aging 750,000-gallon water tanks with two new 1,000,000-gallon tanks that will stand 40 feet tall and have an 80-foot diameter. The existing nonpotable water pumphouse behind Tank #2 will also be demolished and replaced, along with associated piping, valving, and appurtenances. The project includes verifying and completing connections from the existing 12-inch firewater main along Balsam Street and South Circle Drive to the campus’s central kitchen, administration building, and skilled nursing facility sprinkler systems. Construction will occur in two distinct phases, each lasting approximately 12 months, with Phase 1 scheduled to begin in late 2025 and Phase 2 commencing at the end of 2026. The project site is identified by Assessor’s Identification Number 8025-003-902 and is located at the northeastern corner of Balsam Street and 9th Street. All work must comply with state and local regulations, including strict construction hour restrictions under the City of Norwalk Municipal Code, which limit activities between 7:00 a.m. and 6:00 p.m. or sunset, whichever comes first. Special requirements include the mandatory retention of a Native American Monitor approved by the Gabrieleno Band of Mission Indians – Kizh Nation for all ground-disturbing activities, with immediate work stoppage required within 50 feet of any discovered Tribal Cultural Resource. Daily monitoring logs must be maintained, and the Kizh Nation has sole authority over the handling of cultural materials, including human remains, in compliance with California Public Resources Code and Health and Safety Code provisions. Hazardous materials mitigation is required for lead-based paint and asbestos-containing materials, with removal strictly following Cal/OSHA standards based on prior surveys. Environmental compliance is governed by the California Environmental Quality Act, with a Mitigated Negative Declaration issued to document findings and mitigation measures. The project triggers obligations under AB 52 for tribal consultation and requires adherence to the Mitigation Monitoring and Reporting Program for hazardous materials, wildfire risk, and other environmental impacts. While no formal contract clauses or federal acquisition regulations are specified, the procurement is administered under state authority with oversight from the Department of State Hospitals and the Department of General Services, and no federal invoicing
