NIGP 98889: Weed and Vegetation Control (Including Trees, Shrubs and Aquatic Weed Control)

NIGP 98889 Weed and Vegetation Control (Including Trees, Shrubs and Aquatic Weed Control), an Item code, encompasses mowing, trimming, herbicide application, tree removal and pruning, invasive species management, and landscape maintenance across parks, facilities, rights-of-way, stormwater infrastructure, and natural resource areas solicited by state and local governments. State and local opportunities under this code reflect a broad mix of issuing bodies—counties, cities, special districts (flood control districts, transportation authorities, parks departments), and regional authorities—with substantial recent activity in Texas (particularly Harris County Flood Control District, City of Waco, Williamson County, and San Antonio River Authority), California (Orange County Transportation Authority, City of Tucson), Florida (City of Tampa, Orange County, Okaloosa County), Georgia (DeKalb County, Rabun County, Augusta Parks Department), and Oregon. Representative current solicitations include the City of Waco's ITB for FM 1637 ROW mowing (due August 7, 2026), the City of Tampa's grounds maintenance contracts for parks and recreation properties restricted to Small Local Business Enterprises with bid discounts (due June 26 and June 16, 2026), the Orange County Transportation Authority's tree maintenance and pruning services at transit facilities with prevailing wage and DBE participation requirements (due July 20, 2026), and Harris County Flood Control District's riparian management and property boundary vegetation removal services (ITBs due July 20 and August 10, 2026).

Work solicited ranges from routine grounds maintenance at municipal facilities and parks (mowing, edging, debris removal, landscape bed maintenance) to specialized services including certified herbicide application, invasive species and noxious weed control, riparian restoration, tree pruning under ANSI standards, and habitat management at nature preserves and GSI (green stormwater infrastructure) assets. Contract structures vary from one-year terms with optional renewals (three to four additional years typical) to multi-year initial periods and long-term QVLs such as the City of Tucson's five-year GSI landscaping maintenance framework. Many jurisdictions attach prevailing wage requirements, set-asides or bid discounts for small, local, or disadvantaged enterprises, and ISA Certified Arborist or pesticide applicator licensing mandates. Commercial general liability insurance ($1–2 million per occurrence) and performance/payment bonds are standard. Geographic concentration is heaviest in Texas and Florida, with secondary activity across California, Georgia, Oregon, Colorado, Illinois, and Arizona; activity is distributed across both urban municipal parks and facilities as well as regional environmental and stormwater management infrastructure.
