Construction is expected to take approximately three years following asset transfer. The project’s environmental compliance is governed by California law, with all contractual obligations binding on the City, its successors, and assigns in perpetuity. Termination rights allow either party to end the agreement with thirty days’ written notice, and any unenforceable provisions will be severed without voiding the remainder. Administrative costs are outlined in detail, including annual recurring expenses for chip sealing, groundwater monitoring, trench maintenance, and DTSC oversight, with a total estimated contract value of $1,587,331 based on a thirty-year net present value calculation. An advance payment of $2,900 is required within ten days of full execution for DTSC, with quarterly billing and sixty-day payment terms. Contractors must comply with rigorous environmental and safety protocols, including mandatory Worker Environmental Awareness Program training covering protected species avoidance, hazardous material handling per Cal/OSHA standards, and site-specific Health and Safety Plans addressing chemicals of potential concern and emergency response. Extensive documentation, including permits, waste manifests, laboratory analyses, and chains of custody, must be submitted to DTSC upon completion. Attachments and appendices provide supporting technical data on noise, biological resources, air quality, hazardous materials, and historic gas plant sites, ensuring comprehensive regulatory adherence throughout the project lifecycle.
