Sec. 8.01.010. Purpose.
This chapter establishes requirements for the preservation and protection of native trees and the provision of
landscaping, buffering, and screening to provide for the orderly, attractive, and healthful development of land and
promote the health, safety, and general welfare of the community.
A. The regulations contained herein are necessary to protect the character and enhance the ecological,
environmental, and aesthetic qualities of the community.
B. The use of landscape elements can contribute to air purification, oxygen regeneration, water
absorption, water purification, and noise, glare, and heat abatement indicating that the use of
landscape elements is of benefit to the health, welfare, and general well being of the community and,
therefore, it is proper that the use of such elements be required.
C. The City experiences frequent droughts; therefore, it is a purpose of this chapter to encourage the use
of low-water, drought -tolerant plants and trees and the grouping of vegetation by water requirements.
D. The City values its indigenous and historic natural features; therefore, the placement of proposed
buildings and improvements should be oriented in a manner that allows for the preservation of existing
trees and native landscape. In addition, natural areas to be preserved should be integrated within the
design of open space, screening, and landscaped areas.
E. The purpose of the Tree Preservation regulations is to conserve, protect and enhance existing trees and
natural landscapes that are healthy and contribute to the character, safety and health of the City and
ETJ of Georgetown. It is recognized that the presence of trees contributes to the overall quality of life
and environment of the community. Trees are an integral part of air quality, water absorption, water
purification, and noise and heat abatement.

The provisions of this Section 8.02 shall apply to all non-exempt property located within the city limits and
extraterritorial jurisdiction (ETJ) of the City.
1. The City values its trees, and therefore, Protected and Heritage Tree protection may be
considered for priority over conflicting UDC development requirements including, but not limited
to, setbacks, lot design standards, building heights, sidewalks, lighting, signage, parking design
and numbers, drainage criteria, connectivity, driveway separation, and utility extension and
location.
2. If there is a conflict between a Protected or Heritage Tree protection and other provisions of this
Code, the applicant may request an alternative standard or design, provided that public health
and safety shall be maintained with all proposed designs. An alternative standard or design that
gives priority to Protected or Heritage Tree protection may be approved by the Director through
an application for an Administrative Exception under the provisions of UDC Section 3.16
3. All preserved trees may also be credited towards the landscape requirements of this code as
applicable.
4. The Director may increase the amount of permitted impervious cover up to five percent (5%) for
the preservation of Protected Trees beyond the amount required by Subsection 8.02.030.13. A
one -percent (1%) increase in impervious cover may be granted for each one percent (1%) of
Protected Trees preserved beyond the minimum required per 8.02.030.B. For example, a site
required to preserve a minimum of 30 percent (30%) of total Protected Trees may receive a
three -percent (3%) impervious cover bonus by preserving 33 percent (33%) of the Protected
Trees on a site. The maximum impervious cover shall not exceed that specified in Section
11.02.010.
5. The Parkland dedication requirement may be reduced if a Heritage Tree is saved and 100% of the
CRZ is protected within the dedicated Parkland lot in accordance with Section 13.08.030.1) of this
Code, subject to approval by the Parks and Recreation Director.
6. The Director may approve a reduction in the number of parking spaces required by ten percent
(10%) for the preservation of each Heritage Tree, or each Protected Tree. A maximum of a 30
percent (30%) total reduction may be granted under this provision. Any reduction shall only be
granted upon demonstration that the reduction is responsible for the preservation of the
applicable trees
A. Heritage Trees. Heritage Trees on any property located within the city limits and its ETJ may be removed only
with either (1) the approval of a Tree Removal Permit pursuant to Chapter 3 of the UDC or (2) the approval of a
development permit authorizing the removal. Heritage Trees shall not be removed or damaged in rights -of -way or
easements, unless specifically approved by the Planning Director.

a development permit authorizing the removal. For removal of a Protected Tree as part of development of the
property the following preservation requirements will apply:
1. The minimum percentage of Protected Tree inches required to be preserved on site shall be 20 percent
(20%). For multi -site unified developments, the tree preservation percentages may be averaged over the entire
development provided it is identified as such on the Subdivision Plat or Site Development Plan for the development.
Mitigation shall be required for trees approved for removal, using the calculations detailed in Subsection 8.02.040.C.
2. An applicant may preserve less than the minimum percentage of 20 percent provided that the inches of
trees removed beyond the minimum required to be preserved be mitigated at a rate of one and one-half times the
calculations required in Section 8.04.020.
C. Unless otherwise allowed by this chapter, no property shall be clear-cut or selectively cleared, nor shall a Protected
Tree or Heritage Tree be removed, without first securing the necessary approval from the City.
D. Exceptions. Removal of a Heritage or Protected Tree, that otherwise requires City approval, will not require a
permit or other approval from the City in the following situations:
1. Hazardous Trees.
a. Natural Disasters and Other Emergencies. If a Protected Tree or Heritage Tree is determined to be causing a
danger or to be in a hazardous condition due to a natural disaster such as a tornado, fire, storm, flood, or
other similar events that endangers public health, welfare, or safety, the requirements of this section may be
waived as deemed necessary by the Planning Director. The Planning Director shall publish requirements for
documenting the removal to qualify for this standard.
b. Airport Clear Zone. Protected and Heritage Trees located in the Runway Protection Zone, the Airport Clear
Zone, or any other area on the Airport in which trees must be removed based upon the rules and regulations
of the Federal Aviation Administration are exempt from the requirements of this section.
c. Sight Triangles. If the Development Engineer determines a protected or Heritage Tree is interfering with the
safe visibility at a sight triangle of an existing public street, the tree may be removed without fulfilling the
mitigation requirements of this chapter.
d. Dead Trees. The provisions of the mitigation requirements do not apply to a Protected or Heritage Tree that is
already dead or fatally diseased prior to starting a project. Determination shall be made by a Certified Arborist
to execute this exemption.
2. Agriculture Exemptions. Property used agriculturally as defined by this Code shall be exempt from the
requirements specified herein.
3. City of Georgetown Capital Improvement Projects. City of Georgetown utility and transportation capital
improvement projects shall be exempt from the requirements of this section.

providers in the City's right-of-way or public utility easement without prior approval by the Planning Director, if
performed by or under the supervision of an International Society of Arboriculture (ISA) Certified Arborist.
Removal of a Protected or Heritage Tree requested by any utility provider in the City's right-of-way or public utility
easement must be submitted to the Planning Director for review and approval or through a right-of-way permit in
accordance with Chapter 12.08 of the City Code of Ordinances.
5. Platted Residential Exemption. All Residential lots as defined by this chapter platted prior to February 13, 2007.

1. Critical Root Zones.
a. All construction or disturbance shall occur outside of the Critical Root Zone Protection
Zone unless specifically approved.
The Planning Director may approve construction or disturbance closer to the trunk than
one-half the radial distance, depending on the size, spacing, or species of the tree, the
type of disturbance proposed, and uniqueness of the situation, if acceptable
supplemental nutrients and/or soil aeration are provided and the probable survival rate
of the tree is high. In such circumstances, the Director may require the property owner
provide a written report from an ISA certified arborist documenting additional tree care
prescriptions.
Trees grow their root systems in response to the conditions and limitations of their
particular location. Root systems may not reflect the standard Critical Root Zone
configuration described in this chapter. When previous development or existing
conditions have prevented root growth within some portion of the CRZ, the Planning
Director will consider proposals for a modified CRZ. A standard CRZ may include areas
where roots are not present, such as beneath streets or under foundations. The
modified CRZ provides design flexibility in these scenarios. The Planning Director may
require an ISA certified arborist to demonstrate the location of roots prior to approving
a modification to the CRZ
2. Any person who removes a Protected or Heritage Tree in violation of this chapter, accidentally or
otherwise, shall be required to comply with the mitigation provisions of this section, and, if the
act is intentional, to pay a fine for each tree that is removed, as allowed by law, in addition to any
penalties pursuant to Chapter 15. Mitigation for projects without active permits shall be based
on the mitigation provisions applicable at the time of the violation, not those at the time of
platting or other approval
3. Protected and Heritage Trees may be transplanted to a suitable location either on the same
property or off -site, as approved by the Planning Director.
4. Trees to be retained for mitigation or credit shall be encircled with protective fencing in advance
of construction in accordance with the standards as adopted in sections within this UDC and
technical specifications.

It is necessary and desirable to obtain right-of-way for the public street network to support the needs of the
community. Developers share the responsibility of providing adequate streets through compliance with the
minimum standards governing internal and perimeter streets, and the requirement of the Transportation Impact
Fee in Chapter 12.46 of the Code of Ordinances if within the service area boundaries pursuant to Section 12.46.060
of the Code of Ordinances. The developer shall be responsible for the dedication and improvement of internal and
adjacent Future Mobility Plan thoroughfares in accordance with the standards of the street classifications
described in this Section. The requirement for dedication and improvement of internal and adjacent thoroughfares
does not reduce the requirement for payment of a Transportation Impact Fee, except for when such
improvements qualify for and are recorded as a credit in a credit agreement pursuant to the requirements of
Section 12.46.120 of the Code of Ordinances.
The developer is responsible for all costs of materials, design, and construction of the public improvements
required by this Code.
A. The continuation of all existing streets and those included in the Future Mobility Plan, approved plat,
concept plan, or other City -approved document depicting a planned street shall be provided by the
developer.
B. Minimum right-of-way standards shall be in accordance with Table 12.02.030. If the thoroughfare is a
boundary street, one-half of the balance between the street's existing right-of-way and the
street/intersection right -of way required shall be required per Table 12.02.030. Where the
thoroughfare is internal to the property, the full section of right-of-way shall be required.
C. Improvements to Future Mobility Plan streets, in accordance with Subsection 12.09.030.F., shall be the
responsibility of the developer unless otherwise provided. A developer is not responsible for
construction of any bridge structure at the boundary of the subdivision if the bridging of such a street
does not immediately connect to the network. A contribution towards the future construction of the
bridge may be required, as determined by a Traffic Impact Analysis if the cumulative requirement to
build the bridge and other transportation requirements of this Code exceed the approximation of the
roughly proportionate impact of the development.
D. There must be a rough proportionality between the traffic impacts created by a new development and
the associated mitigation requirements. The cumulative transportation requirements of a development
as a condition of development approval may not exceed the roughly proportionate impact of the
development. The approximation of the roughly proportionate impact of a development are
established as the "maximum assessable transportation impact fee" per Section 12.46.040 of the Code
of Ordinances. When a development is phased, the proportionality of requirements shall be assessed

SECTION 32. Z PEDESTRIAN AND BICYCLEMOBILITY
Sec. 12.07.010. General
All sidewalks, sidepaths, shared use paths and trails identified in this Code, the City's Sidewalk Master Plan, Future
Mobility Plan, Parks, Recreation and Open Space Master Plan Element, Trails Master Plan, Downtown Master Plan,
and any other relevant plan shall be constructed in accordance with this Code. Public sidewalks, sidepaths, shared
use paths and trails do not count against the maximum impervious cover percentage required in Section 11.02 of
this Code.
A. Public Sidewalks and Sidepaths.
1. Sidewalks and sidepaths shall be constructed on both sides of all streets, including frontage roads, at
the minimum widths described in Tables 12.03.030 and 12.04.020 of this Code. Sidewalks shall be
constructed consistent with the Construction Manual and in conformance with the requirements
of the Americans with Disabilities Act (ADA).
2. Sidewalks and sidepaths may be located within the street's public utility easement or right-of-way
and may meander in and out of either as approved by the Development Engineer. If located
within the PUE, a public access easement shall be granted by either the recording of a plat or
separate instrument, and shall be identified on any subsequent plans.
3. Sidewalks and sidepaths shall be installed and meet clear zone requirements per the TxDOT
Roadway Design Manual and shall be separated a minimum of six feet from the back of a ribbon
curb
Sidewalk Clear Zone minimums provided in Tables 12.02.030 and 12.03.010. Sidewalks have no
required separation from vertical curbs on a typical local street.
4. Construction of public sidewalks on single-family and two-family lots may be deferred to the building
permit, built to the standards and specifications at the time of the permit. Sidewalks and
sidepaths located in common areas, parks and along Neighborhood Collectors shall be
constructed at the time of street improvements.
S. Pedestrian accessways shall be provided from the public sidewalk and sidepaths to the main
entrance of each building or to a sidewalk leading to the main entrance.
6. Sidewalks and sidepaths located within the Downtown Overlay District shall comply with the design
standards in Section 12.04 of this Code and the Downtown Master Plan, as amended.
7. Sidewalks and sidepaths constructed as infill, retrofitted, or rehabilitation projects should follow the
standards of this Chapter where practical to do so, but consideration shall be given to the existing
conditions of the built and natural environment when locating such sidewalks and sidepaths.
B. Public Trails.
Regional Trails depicted on the Trails Master Plan shall be dedicated and constructed at the time of
development as a public improvement in the general locations and alignments depicted therein.
1. If the trail is not located on public property, a minimum of 20 feet of right-of-way or public access
easement, shall be dedicated as approved by the Director of Parks and Recreation.
2. The trail shall be a minimum often feet in width, constructed to the standards depicted in the Trails
Master Plan, or otherwise approved by the Director of Parks and Recreation.

(Supp. Now 13)
Page 10 of 11
3. A trail constructed to the City°s trail standards may be constructed within the right-of-way or public
utility easement as a substitute for a sidepath if the Trails Master Plan designates a trail along the
street.
C. On -Street Bicycle Lanes.
Bicycle facilities are required along Major Collectors and Arterials at the minimum widths specified in
Table 12.02.030. On Arterial streets, bicycle accommodations are recommended in a side path off of
the vehicular travel lanes for the safety of the cyclists, though the approved cross -sections in Appendix
A allow for on -street striped lanes as well. Design and construction of all bicycle facilities shall meet or
exceed standards set forth in the City°s Future Mobility Plan.
D. Sidewalk Fund.
A designated City fund, entitled "Sidewalk Fund," shall hold any financial contributions paid in
accordance with the provisions in this Code. Funds shall be held in trust by the City to be used
exclusively for the purpose of purchasing and/or equipping public streets for sidewalks or sidepaths:
E. Alternative Pedestrian Improvements.
1. Alternative locations or design variation(s) of sidewalks, sidepaths, pedestrian access facilities, or
hike and bike trails to a standard that deviates from the Construction Manual can be requested
to the Development Engineer. If approved, ownership and maintenance shall be transferred to
the property owner or property/homeowner association and recorded by separate instrument,
along with a public access agreement.
2. When an administrative alternative cannot be achieved, a Subdivision Variance pursuant to Section
3.22 may be requested for either fees -in -lieu of construction, delay of construction, or waiver.
Justifications for the variance include, but are not limited to, the location of the facility in relation
to the existing or planned pedestrian network, the need for the facility, and/or
topography/natural features. Prior to approval of the Final Plat, Site Development Plan, or other
applicable approval stage, payment of any required fees shall be provided for deposit into the
Sidewalk Fund at a cost not to exceed one hundred twenty-five percent (125%) of the estimated
construction plan costs, as approved by the Development Engineer. A request may be made to
City Council for City participation in any pedestrian improvements required by this Chapter.
