Chapter 5
Urban Forestry
(10/6/2014)
Section 5.1 Purpose of This Chapter
The purpose of this chapter is to promote, conserve, and enhance the City’s Urban Forest by:
recognizing the historical and cultural importance of the Eastern Cross Timbers and its impact on
Colleyville; recognizing the environmental, economic, social, and aesthetic benefits of trees;
encouraging and facilitating site planning and design which preserves trees and natural areas;
protecting trees during construction; limiting the removal of trees; providing for the establishment
of a diversity of native and adapted trees.
It is the further intent of this chapter to compliment Destination Colleyville, The City of Colleyville
Comprehensive Master Plan and The City of Colleyville Parks Master Plan as well as maintaining
and enhancing Colleyville’s identity as a Tree City USA.
Section 5.2 Authorization for Adoption of This Chapter
The regulations contained in this chapter have been adopted under the authority of Chapter 51 –
General Powers of Municipalities of the Texas Local Government Code, which authorizes a
municipality to adopt ordinances, rules, or police regulations that are for the good government,
peace, or the trade and commerce of the municipality. This chapter is also adopted under the
authority of the Home Rule Charter of the City of Colleyville, which authorizes the City Council to
exercise all powers granted to municipalities by the Constitution or the laws of the State of Texas.
Section 5.3 Variances and Appeals
Except where provided in this chapter, any person seeking approval of a development as required
by this Land Development Code may request a variance from a requirement contained in this
chapter, or appeal a decision of an Administrative Official by submitting a request using the
procedures described in Chapter 1 – General Provisions of this Land Development Code.
Section 5.4 Definitions
Definitions applicable to this chapter may be found in Chapter 2 – Definitions of this Land
Development Code.
Section 5.5 Tree Removal and Damage
No person directly or indirectly shall cut down, destroy, remove, move, damage, or effectively
destroy through damaging the roots, trunk or canopy, any tree without first obtaining the required
approvals or permits as outlined in this chapter, unless otherwise exempted by the provisions of
this chapter.
Section 5.6 Applicability
A. Prior to the following activities, review and approval of that activity’s compliance with this
chapter (Urban Forestry Review) shall be completed by the Administrative Official unless
subject to the exemptions in Paragraph B:
1. Removal, damage, or adverse impact of any Protected Tree.
2. Construction or expansion of structures for which a building permit is required.
3. Demolition of structures.
Page 5-2
4. Clearing, grading, excavation, filling, or paving on any site or property that has
existing Protected Trees.
5. Subdivision of land into lots by Preliminary Plat, Final Plat, Minor Plat, or Replat.
6. Site plan submittals for commercial or institutional uses as well as site plans that
are part of a PUD, SUP, or other Zoning Case.
B. Exemptions to Urban Forestry Review:
1. Authorized City employees or contractors and authorized Franchise Utility
employees or contractors may, in the course of official business, remove, damage,
or adversely impact Protected Trees or portions thereof which exist in a dedicated
public street right-of-way or a public utility easement which the City or Franchise
Utility has an interest in. The removal, damage, or adverse impact shall be limited
to the extent reasonably necessary to install, maintain, or replace utilities or
infrastructure. If a Tree Preservation Plan is approved showing to preserve trees
in public utility easement or street right-of-way dedicated for new or expanding
streets, then those trees shall be preserved and protected per the approved plans.
Ordinance O-98-1130 shall govern management and control of all trees within City
street right-of-ways, City public parks, and City owned facilities.
2. Any of the above activities may be done without Urban Forestry Review on
properties with an active single-family use that are one (1) acre or less in area and
where a habitable single-family home exists and is occupied as the primary
residence of the landowner. If the landowner owns contiguous individual lots or
tracts, the sum of all land shall be used to determine the size restriction of this
exemption.
3. All landscape nurserymen shall be exempt from the terms and provisions of this
section only in relation to those trees planted and growing on the nursery premises
which are planted and grown for the sale or intended sale to the general public.
Section 5.7 Tree Preservation and Canopy Cover
All new development and redevelopment, to include additions, shall provide a minimum site tree
canopy coverage per this Section through preservation of existing trees and establishment of new
ones.
A. Calculation of Tree Canopy:
1. The canopy area for each existing Protected Tree shall be assumed as a circle
having a radius in feet equal to the DBH in inches of that tree. Example: A 10 inch
DBH tree would have a canopy diameter of 20 feet and a canopy area of 314
square feet.
2. The canopy area for each new tree shall be credited based on the categories of
large, medium, and small canopy trees: Large - 2000 sqft; Medium – 1000 sqft;
Small – 100 sqft. The Administrative Official shall develop, update, and maintain
on file a list of tree species and their associated size category and canopy credit.
B. Non-single-family residential uses:
1. Preservation of a minimum of 50% of the Protected Tree Canopy outside the
Commercial Building Envelope (includes a five (5) foot buffer) shall be required.
2. The total preservation plus tree planting credit shall have a minimum canopy area
equal to 50% of the total area of the lot(s) or tract(s).
C. Development or redevelopment of single-family residential uses on individual lots or tracts:
1. Preservation of a minimum of 50% of the Protected Tree Canopy outside the
Residential Building Envelope (includes a ten (10) foot buffer) shall be required.
2. The total preservation plus tree planting credit shall have a minimum canopy area
equal to 50% of the total area of the lot(s) or tract(s).
Page 5-3
D. Additions and expansions to existing single-family residential uses on individual lots or
tracts:
1. When an addition or expansion to the footprint of a single-family residence equals
50% or more of the existing footprint, the regulations per letter ‘C’ above shall
apply.
E. Development of new single-family residential subdivisions:
1. Preservation of a minimum of 50% of the Protected Tree Canopy on the entire
subdivision shall be required. The calculation shall include Protected trees located
in newly dedicated streets (public or private), public water, sanitary sewer, gas,
electric, telecommunication, drainage and general utility easements. The
calculation shall exclude trees located in existing public utility easements
containing existing in-service water, sanitary sewer, gas, electric, or
telecommunication installations as well as additional public street right-of-way
dedicated adjacent to an existing public or private street. The purpose of not
excluding trees in new streets and easements is to promote subdivision design
and layout that prioritize preservation of trees.
2. Within the required primary building setback areas (non-buildable areas for primary
structure), a minimum of 75% of the Protected Tree Canopy shall be preserved.
This is a separate calculation from that in Paragraph E.1.
3. Once the subdivision is constructed, all improvements are accepted by the City,
the Administrative Official has inspected and verified compliance with required tree
preservation, and Community Development has issued a letter of acceptance
allowing submittal of new single-family building permits, then the preservation
requirements of Paragraph C shall apply and each lot will be reviewed separately
for tree preservation and planting based on that lots remaining trees and proposed
location of single-family home.
F. Artificial Lots:
1. When more than 50% of a lot or tract being developed or redeveloped is to remain
untouched by tree removal, grading, excavation, filling, paving, or building, then an
artificial lot may be delineated around the portion being developed and serve as
the basis for calculation of tree canopy preservation and coverage. The
delineation should not leave small strips or gaps adjacent to property lines and
should generally only leave out one side of a property. Review and pre-approval
of delineation for artificial lots shall be required.
G. Dead, Declining, and Hazardous Trees:
1. Any tree that the Administrative Official determines to be dead, declining beyond
reasonable recovery effort, or that has a high or extreme hazard rating based on
the ISA Basic Tree Risk Assessment that cannot be mitigated to a lower risk, shall
be exempt from inclusion in the review of tree preservation and canopy cover
calculation.
Section 5.8 Heritage Trees
A. Heritage Trees are those specimens that have attained a significant age and are the heritage
of earlier residents of Colleyville or simply pre-date the community. All post oaks and blackjack
oaks 15 inches DBH and larger, cottonwood, water oak, green and white ash 35 inches DBH
and larger, and all other Protected Tree species 25 inches DBH and larger are hereby
considered Heritage Trees.
B. Removal of any Heritage Tree in any location shall require mitigation by one of the following
options:
1. Plant trees with a total canopy credit of five (5) times the canopy area of the
removed tree.
Page 5-4
2. Pay into the City of Colleyville Tree Fund at a rate of $100 per DBH inch.
Section 5.9 Tree Protection Standards
The following procedures shall be followed for all construction projects which involve activity
that required Urban Forestry Review, unless an alternative is deemed appropriate by the
Administrative Official.
