UNSPSC 81151800: Oceanography and hydrology

UNSPSC 81151800 Oceanography and hydrology is a Class code encompassing hydrologic and hydraulic engineering services, watershed and stormwater analysis, flood-risk modeling, and drainage system design and evaluation. State and local governments soliciting under this code procure design and advisory services for watershed master plans, stormwater system improvements, flood forecasting and mitigation, and floodplain management support. Recent opportunities show cities, counties, and special-purpose districts engaging professional engineering firms on continuing-services contracts for hydrologic modeling, lake assessment and restoration, stormwater permitting and compliance, and flood-risk analysis. The Hillsborough County Board of County Commissioners is procuring an automated compound flood forecasting and mapping system valued at $850,000 over four years with an RFP response deadline of September 11, 2026, requiring integration of rainfall, tides, storm surge, and other data into dynamic models supporting cloud-based access and extensive cybersecurity compliance including NIST SP 800-53 v5 Moderate Baseline standards. The City of Casselberry selected four qualified firms—CPH, Inc.; Geosyntec Consultants, Inc.; Vanasse Hangen Brustlin, Inc.; and Wood Environment & Infrastructure Solutions, Inc.—under a Statement of Qualifications for continuing stormwater and lakes management consulting with service areas spanning hydraulic and hydrologic modeling, retention and detention system design, lake assessment and restoration, and watershed management planning.

Recent activity concentrates in Florida, with additional opportunities in Texas. The City of Tallahassee issued an RFQ for watershed master plan development under FEMA HMGP Project 4673-305-P01 with qualifications due October 2, 2026, encompassing watershed data collection, GIS analysis, hydrologic and hydraulic modeling, and flood-mitigation strategy development. Williamson County, Texas is selecting approximately three engineering firms under RFSQ 26RFSQ69 to provide third-party design review and quality assurance for plat and driveway permits, FEMA Floodplain Program administration, and drainage and hydraulic engineering support, with submissions due August 18, 2026. The University of Texas at Austin requested qualifications for a Campus Geological and Hydrogeological Study due July 17, 2026, addressing groundwater intrusion in campus infrastructure and alternative beneficial uses for groundwater. The City of DeBary, Florida solicited competitive bids for Rob Sullivan Park irrigation system improvements under IFB 03-15 with a bid submission deadline of April 10, 2015 and Engineer's estimated cost of $90,000. Issuing bodies include municipalities, county governments, special districts, and higher-education institutions; repeat activity appears across Florida jurisdictions pursuing flood-risk management and watershed planning initiatives funded through FEMA grants and local capital programs.
