Developer / Contractor Resources


 

Forestry has prepared a landscape planning checklist (PDF)  to assist in the plan submittal and review process. Applicants submitting development / landscape plans to the City and County of Denver for review and approval should be aware of the requirements included in the checklist regarding trees in the Public Right of Way.

As a condition of any permit to demolish or construct any building containing a single unit dwelling, two-unit dwelling, or multi-unit dwelling in a Residential Zone District, the owner of the zone lot shall be required to preserve any established tree not otherwise diseased or decayed within the primary and side street setback areas of the zone lot. For a list of current zone districts, click here.
 
In order to protect an established tree from damage or destruction and to enhance the tree's chance of survival after construction activities on the zone lot are completed, the owner shall take and maintain throughout the course of demolition or construction the following measures:
 
A. Erect and maintain temporary fencing surrounding the area beneath the tree in order to mitigate the chance of impact injuries to the tree during demolition or construction;
 
B. Refrain from operating construction equipment or storing construction materials beneath the canopy of the tree or engaging in other activities that would cause the undue compaction of the soil in the tree's root zone; and
 
C. Refrain from any excavation beneath the canopy of the tree that would cause undue destruction of the tree's roots.
 
The owner may be relieved from the requirements of this Section only upon obtaining a permit for tree removal from the City Forester according to the provisions of Sections 57-20(b) and 57-25 of the D.RM.C.

All Public Right-of-Way, Park, Parkway or public space trees are protected by ordinance.  Whenever trees are within or adjacent to a work zone, tree protection is required for the entire duration of the project, all the way through final completion. Information is available at denvergov.org/forestry, click on land developer resources then detail and specification center. The Office of the City Forester should be notified three days prior to commencement of work, please call or email at (720) 913-0651, forestry@denvergov.org.

No access, storage of materials, debris and/or equipment, or activity, including but not limited to, excavation, grading or grade changes, installation of underground utilities, and/or installation of site improvements, is permitted within tree protection zones (TPZ) without prior authorization and instruction from the Office of the City Forester. Any disruption of existing irrigation, the permittee must provide supplemental watering of any trees and landscape impacted as instructed by the Office of the City Forester and/or Parks Representative until the irrigation system is repaired. Removal or alteration of tree protection zones, or damage to public trees, shall result in issuance of penalties which may include compensation of lost value and /or cost of tree removal and replacement.

For plan review submittals, existing trees, notation of proposed retention or removal, tree protection zones, as well as all proposed work within the TPZ or proposed tree planting, must be shown on plans. Tree removals and planting must be approved and issued the required permit by the Office of the City Forester prior to work commencing. Applicants preparing plans should add the Tree Protection (PDF) and/or Tree Planting Details (PDF) to their plans prior to submittal for review. For a list of all plan review requirements, please see the landscape planning checklist (PDF) in the Plan review process section.

One of the things that makes Denver such a beautiful, livable city is our diverse array of trees.  Selecting the right tree for your site assures a healthy tree that will provide many years of benefits and enjoyment.  Denver Forestry has prepared this helpful guide to show you which tree species are recommended and which tree species are not permitted to be planted in the public right-of-way.   For more information contact the City Forestry office at 720-913-0651.
