UNSPSC 70171803: Flood protection or control services

UNSPSC 70171803 Flood protection or control services is a Commodity code capturing state and local procurement of engineering design, construction, and inspection services for stormwater management, drainage improvements, and flood mitigation infrastructure. Recent solicitations show state and local governments buying design and permitting services for detention ponds, stormwater best management practices, drainage system rehabilitation, and pump station upgrades; construction bids for storm sewer replacement, drainage conveyance improvements, and flood-mitigation channel projects; and on-call maintenance and cleaning of drainage pipes and structures. Issuing bodies include county governments (Pasco County, Orange County, Galveston County, Clay County, Flagler County, Harris County Flood Control District), cities (Orlando, Brownsville, Alpharetta, Norwalk), special districts (West Basin Municipal Water District), and state agencies (Georgia Department of Transportation). Water districts and county flood control authorities appear as repeat buyers. Representative recent work spans on-call professional engineering services for water districts (West Basin, RFP RFPTH0128, proposals due July 14, 2026, estimated $3 million across five awards), drainage construction (Pasco County underdrain installation and repair, IFB Y26-1003, due August 4, 2026, $19.6 million five-year contract value), design services for flood mitigation (City of Orlando drainwell replacement, RFQ RQS260249, due June 11, 2026), and stormwater infrastructure design (multiple design and engineering RFPs in Georgia, Florida, Texas, and Connecticut with July through August 2026 due dates).

Geographic concentration spans Florida (Orange County, Pasco County, Flagler County, Clay County, Broward County, Sarasota County), Georgia (Alpharetta, Dalton, DeKalb County, GDOT Districts 3/6/7), Texas (Harris County, Galveston County, Cameron County, San Antonio River Authority, Burnet County), California (West Basin in Los Angeles area), Connecticut (Norwalk), and Ohio (Cincinnati). Activity is heaviest in Florida and Georgia, with significant ongoing work in Texas and scattered state-level design procurement in the upper Midwest and Northeast. The code reflects sustained demand for both capital project engineering (design and bidding support) and construction services (pipe installation, pond construction, conveyance system upgrade), with contract values ranging from under $200,000 for small park drainage improvements to over $19 million for multi-year maintenance agreements, indicating a mature market with routine project cycles and recurring on-call service needs.
