Longmont's tree code lives in LMC Title 13 (Streets, Sidewalks, Public Places) Chapter 13.24 'Trees and Plants' and LMC Title 6 Chapter 6.88 'Tree Contractor License.' Together they govern responsibility (13.24.020), protection of high-value trees (13.24.110), abatement of dead/hazardous trees (13.24.160), and require contractor licensing for all aloft work. Longmont Forestry Services administers the program.
LMC Chapter 13.24 (Trees and Plants) is the city's master tree ordinance, covering: 13.24.020 Responsibility of adjacent owners (care, maintenance, and removal to the center of the alley); 13.24.110 Tree Protection — appraisal and mitigation for healthy, high-value trees; 13.24.160 Abatement of dead/hazardous trees and unwanted plants; and authority for Forestry Services to permit and inspect work on City and ROW trees. LMC Chapter 6.88 (Tree Contractor License) requires anyone performing aloft pruning or removal of trees within the city limits to hold a Longmont Tree Contractor License with $1,000,000 liability insurance, ISA-certified arborist on staff, $60 fee, and a passed field test. The City supports the urban forest with EAB management (43,000 estimated ash trees citywide, 2,800 City-maintained), Tree City USA designation, and the 2020 Forestry Standards and Specifications which set technical standards aligned with ANSI A300 and ISA BMPs.
Common citations: (1) unlicensed tree work — contractor charged under LMC 6.88; (2) unpermitted work on a city/ROW tree — owner or contractor liable for appraised-value mitigation under LMC 13.24.110; (3) failure to maintain or remove a dead/hazardous tree after Code Enforcement notice — abatement under LMC 13.24.160 at owner's cost. Penalties scale up for repeat violations.
