Pruning of city-owned trees and trees in the public right-of-way requires a permit from Longmont Forestry Services and must be performed by a City of Longmont Licensed Tree Contractor under LMC Chapter 6.88. Work must follow ANSI A300 standards and ISA Best Management Practices.
Per LMC Chapter 13.24 (Trees and Plants) and Chapter 6.88 (Tree Contractor License), any pruning, removal, or plant-health-care work on a City-owned/maintained tree, or work on a tree in the public ROW, requires a Forestry Services permit. Permits are submitted online and processed within five business days. Adjacent property owners are responsible for trees in the ROW abutting their property unless the City has assumed maintenance. All commercial pruning must be performed by a contractor holding a Longmont Tree Contractor License (LMC 6.88), which requires $1,000,000 general liability insurance, an ISA Certified Arborist on staff, a passed practical climbing/pruning field test, and a $60 annual fee. Soil injections and aerial sprays on ROW trees are prohibited.
Unpermitted pruning, topping or improper cuts on a city or ROW tree can trigger appraisal of damages by the City Forester and mitigation/replacement under LMC 13.24.110. Hiring an unlicensed contractor to perform aloft tree work in Longmont is a violation of LMC Chapter 6.88 against the contractor and may invalidate any work performed.
