Unit W Wastewater Interceptor Condition Assessment

The City of Thousand Oaks is undertaking a targeted infrastructure assessment and repair project for the Unit W Wastewater Interceptor, authorized under an amended Lake and Streambed Alteration Agreement issued by the California Department of Fish and Wildlife. The scope includes assessing the internal condition of the interceptor and replacing damaged isolation valves at four key locations: Structures W-A, W-D, W-1, and the Shapell lateral, along with installing two pipe access tees via temporary excavation. The work also involves constructing four temporary culvert creek crossings over a local waterway, with materials and methods revised in 2025 following storm damage that compromised earlier crossings. The amended approach ensures all new crossings fully span the creek without placing any materials within the channel, eliminating additional environmental impact. The project is governed by Section 1602 of the Fish and Game Code and complies with state environmental review requirements under CEQA, supported by a Mitigated Negative Declaration and a Mitigation Monitoring and Reporting Plan. All work is confined to the project site at the terminus of Hill Canyon Road in Thousand Oaks, California, with specific parcel identifiers provided for location accuracy. The City of Thousand Oaks serves as the permittee and responsible party for execution, while the California Department of Fish and Wildlife retains oversight authority as the regulatory agency. Contract administration details are limited, with no formal contract type specified, no pricing data available, and no explicit invoicing, payment, or accounting codes provided. Key points of contact include Nader Heydari, the Public Works Director representing the City, and Angela Castanon of CDFW as the environmental liaison. No formal representation, certification, or socioeconomic status information for the offeror is documented, and the procurement structure relies on the amended environmental permit rather than a standard federal acquisition format. The period of performance and delivery schedule are not explicitly defined, and no special contractual requirements beyond environmental compliance and construction methodology are outlined.
