On-Call Third Party Review and Modeling Services

The Sacramento County Water Agency is conducting a procurement for On-Call Third Party Review and Modeling Services, seeking professional engineering consultants to provide comprehensive drainage study and improvement plan reviews for development projects within unincorporated Sacramento County. The solicitation, released on January 14, 2025, covers third-party technical reviews to verify modeling techniques, ensure compliance with county hydrology and hydraulic standards, and assess stormwater quality regulatory requirements. Qualified consultants will be expected to perform services including drainage study reviews, hydrologic and hydraulic modeling, master drainage study development, CLOMR/LOMR FEMA submittals, and participating in agency and developer meetings. Review timelines are structured with large drainage studies having negotiated review periods and smaller studies limited to 20 business days for initial submittals and 15 business days for resubmittals. Key evaluation criteria will likely include technical expertise, experience with drainage modeling software, understanding of local regulatory requirements, and ability to meet prescribed review timelines. Proposal questions were due by February 7, 2025, with final proposals required by February 20, 2025.

The agency anticipates awarding three separate on-call contracts, each valued at $100,000, with an estimated two-year contract duration beginning in 2025. While specific set-aside designations are not explicitly detailed in the available documentation, the procurement appears open to professional engineering consulting firms with demonstrated expertise in drainage and hydraulic modeling. The solicitation covers jurisdictions including Sacramento County and San Francisco City, suggesting potential regional implementation of the contracted services. Consultants will be required to utilize various modeling software tools and work collaboratively with Agency staff throughout the review process. The comprehensive nature of the procurement indicates a preference for firms with robust technical capabilities, professional certifications, and proven experience in municipal water agency drainage and stormwater management review processes. The total potential contract value across the three awards is estimated at $300,000, providing multiple firms the opportunity to secure on-call engineering review services.
