Central Contra Costa Sanitary District (Central San) is soliciting statements of qualifications from up to four consulting firms for as-needed soil management and compliance support services covering 2027 through 2032, with questions due November 20, 2026 and qualifications due December 11, 2026 at 4:00 p.m. Submittals go through PlanetBids. No set-aside or preference program is stated. Office location is a preferred qualification, not a requirement.

Scope covers clean soil data review, air monitoring during excavation, design and construction support for soil-disturbing projects, regulatory coordination with the Department of Toxic Substances Control (DTSC), soil treatability pilot study implementation, long-term monitoring of capped property areas, and miscellaneous environmental compliance support. Work is performed at Central San's wastewater treatment facility in Martinez, California.

Qualified firms must demonstrate five years of professional environmental consulting experience and two completed soil management projects within the last five years. The Project Manager needs ten years of contaminated soil management experience and current California professional engineer or geologist licensure, with preferred DTSC oversight experience. The Subject Matter Expert needs fifteen years of municipal environmental compliance experience, with preferred DTSC project management background. Consultants must provide proof of required insurance and accept the sample agreement terms without exceptions before award.

The five-year term carries no renewal options. Compensation is time and materials, with an annual cost range of $30,000 to $200,000, subject to a firm cost ceiling per the fee schedule. Proposers must state maximum annual rate increases for 2028 through 2032. Central San does not guarantee work volume.

Top-ranked consultants will be interviewed February 8–11, 2027, with selection notifications February 22–26, 2027, and agreements anticipated in May 2027.
