Upcoming changes to Aspen’s tree code: wildfire risk and tree protection
Aspen, CO – The city of Aspen has announced important updates to its tree code aimed at addressing wildfire risk while continuing to protect the city’s valuable urban forest. These changes focus on wildfire mitigation and updated standards for tree protection during construction.
In response to increasing homeowner requests for wildfire risk reduction, the city’s Parks and Open Space Department, in collaboration with the Aspen Fire Protection District (AFPD), has revised its tree removal policy. These updates reflect best practices in wildfire mitigation while safeguarding the health of the local forest.
Wildfire Mitigation Policy
The newly adopted Wildfire Mitigation Policy provides a clear framework for homeowners seeking to remove trees to reduce wildfire risk. The process includes the following steps:
Home Assessment: Homeowners will schedule a free assessment with the AFPD to evaluate their property’s wildfire risk.
Permit Application: After the assessment, homeowners apply for a tree removal permit with the city’s Parks and Open Space department, including the assessment findings in their submission.
Onsite Evaluation: The city forester will visit the property to discuss the proposed tree removal and determine final approvals based on the new wildfire mitigation matrix.
Tree Removal: Once a permit is issued, homeowners or licensed tree care providers may proceed with the approved removals.
Replanting: In some cases, homeowners will be asked to replant fire-resistant trees, with the city forester conducting an inspection after replanting is completed.
This policy integrates national Firewise guidelines, a set of recommendations for reducing the risk of wildfires in communities, to ensure the removal process balances wildfire protection with long-term forest health.
Critical Root Zone (CRZ) Update
In addition to the wildfire mitigation measures, the city has updated its tree protection code to more accurately reflect the needs of a tree's root system during development. The previously used term “dripline” has been replaced with Critical Root Zone (CRZ), which is now defined in the municipal code.
The CRZ more accurately represents a given tree's root structure, simplifying the development process and providing clearer guidelines for builders. The CRZ ensures that tree roots are adequately protected during construction, preserving tree health and reducing damage risks.
