UNSPSC 30121711: Natural curbstone

UNSPSC 30121711 Natural curbstone is a Commodity code under which state and local governments procure decorative and functional stone materials for roadway, landscape, and hardscape applications. Recent solicitations show the code capturing a narrow range of stone products and installation services — primarily decorative aggregate (river rock, flagstone, sandstone, crusher fine, rip-rap, and recycled asphalt), fill materials (topsoil, fill dirt), and erosion control supplies — rather than traditional curbstone as the code name might suggest. Issuing bodies include county consolidated governments, municipal parks departments, county transportation and public works agencies, and state departments, with Boulder County Parks and Open Space, Columbus Consolidated Government (Georgia), the City of Fairburn (Georgia), and the State of Georgia appearing in recent postings. The work ranges from annual commodity supply contracts on an as-needed basis to standalone landscape enhancement projects and short-list qualifications for multiple small projects across five-year periods.

Activity is concentrated in the Southeast, particularly Georgia and Florida, with recent opportunities also in Colorado and Connecticut. Representative recent solicitations include Columbus Consolidated Government's RFB 26-0037 (posted May 14, 2026, due June 17, 2026) for annual stone supply — fourteen classifications including #3, #34, and #5 stone, crushed stone base, and rip-rap, with an estimated 200 tons monthly usage and two-year initial term plus three optional one-year renewals; Boulder County Parks and Open Space SOQ28626 (posted May 6, 2026, due May 27, 2026) seeking a pre-qualified vendor list for landscaping and erosion control materials on a five-year project-by-project basis; and the City of Fairburn IFB 26-013 (posted May 21, 2026, due June 16, 2026) for landscape enhancement within roadway medians including decorative rock installation and plantings. The Williamson County notice and Sourcewell's law enforcement equipment RFP are unrelated to the code's scope and should be disregarded.
