Watershed Master Plans for Nassau River Basin & St. Mary's River Basin

Nassau County Board of County Commissioners is requesting proposals for watershed planning services to develop Watershed Master Plans for the Nassau River Basin and St. Mary's River Basin under RFP NC26-015-RFP, with proposals due October 7, 2026 at 10:00 a.m. ET. The projects are funded through the Florida Division of Emergency Management Hazard Mitigation Grant Program and administered under FEMA requirements.

The scope encompasses professional watershed planning services including hydrologic and hydraulic modeling, GIS analysis, flood risk assessment, mapping, public and stakeholder coordination, and reporting to satisfy grant requirements and Community Rating System (CRS) compliance. Bidders must demonstrate qualifications in watershed planning, flood risk assessment, CRS compliance, federally funded mitigation projects, and experience with municipalities comparable to Nassau County. At least three relevant references from projects completed within the past five years are required. Professional liability insurance with minimum coverage of $1,000,000 per occurrence is mandatory.

Combined available funding is $632,136.30: Nassau River Basin Watershed Master Plan, $300,000; St. Mary's River Basin Watershed Master Plan, $332,136.30. These amounts represent the maximum available for each respective watershed, with no additional grant or County funds available; costs exceeding available funding are the Bidder's sole responsibility. Each project is funded through separate grant awards and invoices must separately account for work performed under each project.

Contract term begins upon execution with all required deliverables completed no later than February 29, 2028. The contract remains in effect through August 31, 2028 to allow for revisions, corrections, supplemental documentation, technical support, and grant closeout. Evaluation criteria are weighted as follows: Experience/Qualifications/References (25 points), Understanding of Scope & Technical Project Approach (35 points), CRS expertise (15 points), Grant Compliance (15 points), and Project Management (10 points). Questions are due September 28, 2026 by 2:00 p.m., with County responses posted by October 2. All proposals must be submitted electronically via PlanetBids; mailed, facsimile, or emailed proposals will not be accepted. Payment is contingent upon County acceptance of deliverables.
