Stormwater to Sewer Diversion and Reuse Project at Ocho Rios Way (CI 5600)

The City of Thousand Oaks, in coordination with Ventura County, the Las Virgenes Municipal Water District (LVMWD), and the Triunfo Water and Sanitation District (TWSD), is seeking qualified professional engineering firms to design and engineer a stormwater diversion system at Ocho Rios Way (Project CI 5600) within the Upper Malibu Creek Watershed in Ventura County, California. This Request for Proposals/Qualifications (RFP/Q) procurement seeks design and bidding phase services to develop a stormwater diversion structure that will redirect dry weather stormwater flows (anticipated at up to 5 gallons per minute) from the storm drain system to the downstream sanitary sewer system for conveyance to the Tapia Water Reclamation Facility (TWRF) for treatment. The primary project objective is to reduce bacteria and nutrient concentrations (Total Maximum Daily Loads) discharged into the Malibu Creek Watershed to comply with Los Angeles Regional Water Quality Control Board regulations and the Municipal Separate Storm Sewer System Permit. Deliverables include a kickoff meeting, preliminary investigation (background document review, site investigation, topographic and utility survey), project scoping workshop with public outreach, design phases at 30%, 60%, 90%, and 100% completion levels, identification and location of existing utilities, geotechnical investigation, project status and coordination meetings, City Council presentation, and bid support services, with construction support services potentially issued as a future amendment. Proposers must meet California Labor Code prevailing wage requirements (Section 1771) and apprenticeship requirements (Section 1777.5) for public works contracts exceeding $30,000, demonstrate necessary qualifications and experience, maintain comprehensive insurance coverage including Commercial General Liability ($2,000,000 per occurrence/$4,000,000 aggregate), Automobile Liability ($1,000,000 combined single limit), Workers' Compensation ($1,000,000 employer's liability limits), and Professional Errors and Omissions coverage ($1,000,000 per occurrence/$2,000,000 aggregate with three-year tail). The solicitation was released on March 27, 2026, with a question submission deadline of April 14, 2026, and a proposal submission deadline of April 29, 2026, at 5:00 p.m. via the City's eProcurement Portal; the anticipated award timeline includes proposal evaluation in May 2026, finalist interviews and contract negotiations in May 2026, City Council award authorization in June 2026, agreement execution in July 2026, work commencement in July 2026, and project completion by February 2027.

The procurement is subject to federal EPA Community Grant funding and must comply with 2 CFR Part 200 procurement standards, requiring all proposers to certify non-debarment status, comply with the Byrd Anti-Lobbying Amendment, and avoid use of covered telecommunications equipment. Proposers must comply with EPA Disadvantaged Business Enterprise (DBE) program requirements under 40 CFR Part 33, including DBE utilization goals, six good faith efforts documentation, and quarterly or annual reporting using EPA Form 5700-52A; the procurement mandates full and open competition without geographic preferences. No specific set-asides or incumbent vendor preferences are identified in the solicitation documents, though proposers must register with the City's eProcurement Portal using NIGP Code 96800 and maintain a valid City of Thousand Oaks Business License prior to contract execution. Required submissions include a completed W-9 form, Non-Collusion Affidavit, and Levine Act Disclosure Form with all proposals. Compensation is structured on an hourly basis with expenses reimbursed, with proposers required to submit a detailed cost breakdown including hourly rates, reimbursables, and maximum anticipated costs not to exceed a specified amount, though the exact contract value or budget range is not explicitly disclosed in the available solicitation documents. The project will integrate with existing infrastructure including coordination with TWRF operated jointly by LVMWD and TWSD through the Las Virgenes-Triunfo Joint Powers Authority, and the existing stormwater and sewer systems serving the Ocho Rios Way area.
