This closed solicitation seeks on‑call consulting services for Yolo County, covering three distinct groups: Geotechnical Services, Environmental Engineering Services, and Environmental Planning & Permitting Services. The county intends to maintain a roster of qualified firms that can be called upon as needed for projects related to soil investigations, environmental impact assessments, and permitting processes. • Scope includes geotechnical analysis (soil testing, foundation recommendations, slope stability) for public infrastructure projects. • Environmental engineering tasks involve remediation design, stormwater management, and compliance with state/federal environmental regulations. • Planning and permitting services cover preparation of environmental impact reports, permit applications, and liaison with regulatory agencies. • Services are on‑call, meaning the contractor must be ready to mobilize quickly when the county issues work orders. • The contract likely spans multiple years with periodic task orders rather than a single fixed‑price award.
