Tree removal permit rules in Longmont, CO — sometimes called heritage tree, protected tree, or street tree ordinances — list which trees require a permit before you can cut them down.
Removal of a healthy, high-value tree on City property or in the public ROW requires a Forestry Services permit and triggers appraisal and mitigation under LMC 13.24.110. The City Forester sets the appraised value, and equivalent replacement value must be paid or planted. Stump grinding is required with every approved removal.
Per the City of Longmont Forestry Services permit page and LMC Chapter 13.24, removal of a city-maintained tree or a ROW tree requires a Forestry permit issued within ~5 business days. Healthy, high-value tree removals fall under LMC 13.24.110 (Tree Protection): the City Forester appraises the tree using the International Society of Arboriculture trunk-formula method, and the applicant must provide equivalent mitigation (in-kind replacement trees or a payment in lieu). Stump grinding is required as part of every removal. Removal must be performed by a Longmont Licensed Tree Contractor (LMC 6.88). EAB-killed ash trees on private property are handled under Code Enforcement's pre-code-enforcement letter process before formal nuisance abatement.
Removing a city or ROW tree without a permit triggers an appraised-value charge under LMC 13.24.110 plus mitigation. Dead, hazardous, or EAB-infested private trees that are not addressed after Code Enforcement notice can result in municipal nuisance citations and a city-contracted removal billed back to the owner.
