Description: The Sites Project Authority (Sites Authority) is requesting Proposals for the Sites Reservoir Project Terrestrial Compensatory Mitigation contract (Compensatory Mitigation Contract). This RFP (RFP No. 26-05) initiates Step 2 of a two-step procurement process (RFQ then RFP) under Public Contract Code section 20928 et seq. Only RFQ-shortlisted respondents are eligible to submit Proposals. Shortlisted RFQ respondents named in this RFP (listed alphabetically) are: HGS, LLC dba RES Environmental Operating Company, LLC; and Westervelt Ecological Services. Overview and purpose: The selected Compensatory Mitigation Contractor will develop and implement a comprehensive terrestrial compensatory mitigation program to satisfy the Sites Reservoir Project's terrestrial mitigation requirements under applicable federal, State, and local permits and environmental commitments. Responsibilities include planning, site identification and acquisition or conservation easement negotiation, preparation of mitigation and habitat plans, obtaining applicable permits and regulatory approvals for mitigation actions, implementation and construction of restoration activities where required, interim and long-term stewardship and monitoring, establishment and funding of long-term stewardship endowments, providing surety in the form of payment and performance bonds, and coordination with the Sites Authority, Resource Agencies, Project Partners, construction contractors, Tribal Nations, Local Community Working Group, and other stakeholders. The contract contemplates phased Task Orders covering: (1) Planning/Early Implementation Phase Services; (2) Mitigation Phase 1 (early impacts); (3) Mitigation Phase 2 (majority of mitigation needs); and (4) Mitigation Phase 3 (final reservoir inundation area). Procurement process and evaluation: This is a best-value, two-step procurement. The RFP describes the Sites Authority's Evaluation Committee, evaluation criteria and weighting (Criterion 1: alignment with Authority values and partnership expectations 20%; Criterion 2: community engagement, tribal coordination, and third-party engagement 15%; Criterion 3: execution plan 35%; Criterion 4: compensatory mitigation, pricing, and cost management 30%), potential interviews (optional), reference checking (optional), negotiations with the highest ranked Proposer, and Authority Board approval/authorization. The RFP allows the Sites Authority broad procurement rights (e.g., amend or cancel the RFP, waive non-material defects, reject proposals, negotiate with next-ranked proposers if negotiations fail).
