Chapter 9—Subdivision Design&Public Facilities Page 9-1
Exhibit "A"
Coffeyville, Texas,Land Development Code
2. Whenever a developer can demonstrate an alternative method of meeting the requirements of this Land
Development Code, it shall be incumbent upon the city staff, the Planning and Zoning Commission,
and the City Council to review the proposed variations and approve, approve with modifications, or
disapprove the proposed alternatives as appropriate for the conditions.
Section 9.6 Blocks
A. General Design — Blocks should have sufficient depth to provide for two (2) tiers of lots of appropriate
depths,except that blocks adjacent to major streets, railroads or waterways shall have only one tier of lots.
B. Block Lengths & Widths — Residential and industrial blocks generally shall be no longer than sixteen
hundred(1,600)feet and business blocks no longer than one thousand (1,000)feet. Where long blocks in
the vicinity of a school,park or shopping center are proposed,the City Council may require a public walkway
near the middle of long blocks or opposite a street that terminates between the streets at the ends of the
block.
Section 9.7 Lots
A. Lot Arrangement — Lots shall be arranged to provide access to lots from approved streets and to avoid
foreseeable difficulties due to topography and natural physical features inherent to the property.
B. Lot Area and Dimensions—Lot area and dimensions shall be consistent with the minimum requirements of
the applicable zoning district and the following:
1. Special Lot Width Requirement-The width between side lot lines at their foremost points(where they
intersect with the street line)shall not be less than eighty(80)percent of the required lot width. In the
case of lots on the turning circle of a cul-de-sac, the width may be less than eighty(80) percent of the
required lot width.
2. The City may approve a plat which contains a lot that does not meet the minimum requirements when
special conditions exist.
C. Frontage on Public Access Required — All lots shall have frontage on a public street, except a non-
residential lot may be approved when the proposed public access has been determined by City to be
adequate to meet the intent of this requirement. The lot line common to the street right-of-way line shall be
the front line; except that a lot may have more than one lot line common to a street right-of-way line.
D. Access from Major Thoroughfares
1. Residential Lots-No residential lot shall front on or derive access directly from an existing or proposed
collector street, or larger, as shown on the Master Thoroughfare Plan, except where the proposed
subdivision meets all the following criteria:
a. Where the only street frontage which may be provided to the residential lot is from a collector
street due to the shape, topography, or other physical condition of the property;
b. The Director of Public Works or designee has provided favorable recommendation; and.
c. Where the residential lot is designed and dimensioned to permit loop driveways or on-site
turnaround facilities so that vehicles head into the collector street.
2. Non-residential Lots—Non-residential lots which have frontage onto or derive access directly from an
existing or proposed collector street, or larger, as shown on the Master Thoroughfare Plan, shall have
driveway locations which comply with the spacing requirements established elsewhere in Chapter 14
—Engineering Design Standards of this Land Development Code.

Exhibit "A"
Colleyville, Texas,Land Development Code
E. Buildable Area — Every lot shall contain a buildable area that is adequate in size for the proposed
development. The buildable area shall be situated out of the 100 year flood plain.
F. Flaq Lots Prohibited — It is the policy of the City to prohibit the creation of flag lots unnecessarily, and to
discourage the creation of any lot which, by virtue of its relatively great depth in relation to its width, is likely
to facilitate future requests for re-subdivision to create a flag lot.
G. Building Lines— Front building lines shall be shown on all lots in the subdivision. Building lines shall be
shown along each street-facing of corner lots and through-lots. The building line shall be consistent with
the requirements of the applicable zoning district, however, the City may approve a building line which
differs from the zoning requirements when special conditions exist.
H. Side Lot Lines—Where possible, all side lot lines shall be at right angles to straight street lines and radial
to curved street lines.
I. Lot Drainage and Grading
1. Grading and drainage of all lots shall be designed in a manner which will allow one lot to drain across
an adjacent lot and into a permanent structure, such as a concrete flume, lined channel,or proper inlet
to an adequate drainage facility, or to a street right-of-way. If an approved drainage structure is not
present, it will be required of the developer to construct the necessary facilities. (0-00-1261/12-19-00)
2. Sheet flow techniques shall be used for lot to lot drainage where possible. (0-00-1261 i 12-19-00)
3. Single lots shall accommodate their own drainage into an approved structure where topographic
elevations allow this to occur. (0-00-1261/12-19-00)
4. For lots that an approved engineered grading plan does not exist,the developer of the site shall submit
a grading plan prepared by a licensed Professional Engineer.
Section 9.8 Waterbodies and Water Courses
If a tract being subdivided contains a water body, or portion thereof, lot lines shall be drawn so as to distribute
the entire ownership of the water body among the adjacent lots. The City may approve an alternate plan
provided the ownership of and responsibility for maintenance of the water body is so placed that it will not
become a City responsibility. Where a watercourse separates the buildable area of a lot from the street by
which it has access, provision shall be made for installation of a culvert or other structure, of design approved
by the City. Any lot which includes a water body and contains a building site, shall contain a buildable area that
is not less than the minimum buildable area for the applicable zoning district.
Section 9.9 Street Names
The developer shall submit all existing and proposed street names on any proposed subdivision plat. New
street names shall be sufficiently different in sound and in spelling from other road names in the city so as to
not cause confusion to the general public or for emergency response. A road which is, or planned, as a
continuation of an existing road shall bear the same name.
Section 9.10 Reserve Strips and Common Areas
The creation of reserve strips shall not be permitted adjacent to a proposed street or to adjacent property in
such a manner as to deny access from adjacent property to the street. No common areas shall be allowed in
a subdivision except where notation has been placed on the plat to prohibit development on the common area.

Section 9.11 Double Frontage Lots
Double frontage and reversed frontage lots shall be avoided except where necessary to provide separation of
residential development from a collector street or to overcome specific disadvantages of topography and
orientation.The City may require that a notation be placed on the plat to limit the facing of main structures or to
limit driveway access from a collector street.
Section 9.12 General Infrastructure Policy
(03-03-09/0-09-1712)
A. General Requirement—The developer of a subdivision shall install all water, sewer, street, sidewalk and
drainage improvements, and any other facilities required by this Land Development Code, which are
necessary for the proper development of the subdivision. The design, construction and inspection of any
public facilities shall be a cost to the developer, unless the City has entered into an agreement for cost
sharing. All such facilities shall be designed and constructed in accordance with the criteria contained in
this Land Development Code and be in conformance with the general layout of the City of Colleyville Master
Land Use Plan and Capital Improvements Plan. The public facility requirement of this section shall be
applicable to the upgrading of any existing facilities which do not meet current standards.
B. Apportionment of Infrastructure Costs —As a condition of the approval of a development, the developer's
portion of the costs may not exceed the amount required for infrastructure improvements that are roughly
proportionate to the projected impact of the proposed development, as determined by a professional
engineer, licensed in the State of Texas, and who is retained by the City of Colleyville.
1. In making the rough proportionality determination, consideration shall be given to the availability of
adequate and minimum levels of public facilities and accessibility to the site for delivery of emergency
services.
2. The professional engineer making the proportionality determination may rely on categorical findings
from comparable public improvement projects for establishing a cost basis. The basis used for
determining estimated costs shall be revised annually on July 1 by the Colleyville Engineering
Department.
3. A developer who disputes the determination by said professional engineer may appeal to the City
Council and present testimony and evidence in support of the appeal. The appeal shall be written and
filed with the City Secretary within ten(10)days after the date action taken by the Planning and Zoning
Commission on the development proposal. The developer shall not be required to waive the right to
appeal as a condition of approval of the development project.
C. Optional Escrow Provision—Where, in the opinion of the City,construction of a required public improvement
should be deferred to a future date, the developer shall place in escrow with the City, an amount equal to
the estimated cost of the improvements, as determined by the the Director of Public Works or designee.
The Planning and Zoning Commission or City Council may consider an alternate arrangement when
appropriate. Any escrow related to the construction of sidewalks shall adhere to the requirements set forth
in Section F.
D. City Participation in Over-Sizing — Where over-sizing of a public improvement is required by the
Comprehensive Master Plan, Thoroughfare Plan, Water or Sewer Capital Improvements Plan or other
planning document adopted by the City, City participation shall be in accordance with the provisions of any
applicable Impact Fee Ordinance or City-Developer Agreement, which has been approved by the City
Council.
E. Public Easements—All public improvements shall be constructed within easements or rights-of-way that
have been dedicated for public use. The width of an easement or right-of-way shall be in accordance with
the specifications contained elsewhere in this Land Development Code.
F. Escrow Policy for Sidewalks
Chapter 9—Subdivision Design&Public Facilities Page 9-4
Exhibit "A"
Colleyville, Texas,Land Development Code
1. Request for Escrow
Whenever these regulations require a property owner to construct a sidewalk for a dwelling unit, the
property owner may petition the City for deposit of an escrowed amount, as established in this
Section, in lieu of the required construction of a sidewalk.The Director of Public Works or designee
shall determine whether the escrow is reasonable in lieu of the obligation to construct the
improvement. If an escrow request is denied,then the applicant may appeal that denial to the City
Council if a written request for appeal is received by the Director of Public Works or designee within
ten (10)days of the denial.
2. Deposit with the City
Whenever the City agrees to accept escrow deposits in lieu of construction by the owner of the
property under these regulations, the property owner or developer shall deposit an amount equal to
his share of the costs of design and construction in escrow with the City. This amount shall be paid
prior to release of construction plans by the Director of Public Works.The obligations and
responsibilities of the property owner shall become those of the property owner's transferees, heirs,
successors, and assigns; and the liability therefore shall be joint and several.
3. Determination of Escrow Amount
The amount of the escrow shall be determined by using the average of the comparable bids awarded
by the City in the preceding six(6) months for sidewalk design and construction or, if none exist,then
current market value of the design and construction of a sidewalk in the City,to be determined by the
Director of Public Works. The determination shall be based on reasonable current market value made
as of the time the escrow is due.
4. Use of Escrow Funds
Six(6) Sidewalk Districts are hereby established throughout the City. These districts shall share the
same boundaries as the six(6)neighborhoods depicted on the Neighborhood Boundary Map in the
2004—2025 Colleyville Plan. The Sidewalk Districts are established so that sidewalk escrow funds
will be expended within sufficient proximity to the dwelling unit that deposited the sidewalk escrow fee
so as to reasonably benefit that dwelling unit. Funds escrowed pursuant to this Land Development
Code shall be expended on design and construction of sidewalks located at any place within the
same Sidewalk District as the dwelling unit depositing the sidewalk escrow fee.
5. Existing Escrow Funds
All funds currently escrowed in lieu of sidewalk construction before the effective date of this
Ordinance are subject to expenditure under this Ordinance unless a written objection is filed,by
the owner of the lot for which the funds are escrowed, with the Director of Community
Development within thirty(30) days after notice of this Ordinance is received. Notice of this
Ordinance shall be sent to the current owner of the lot for which the funds are escrowed at the
address listed in the most recent tax rolls of the City. If the person receiving notice under this
subsection is not the current owner, then they must immediately notify the City of the person
who purchased the property and provide the City with the address of that person.
ii. If an objection is filed pursuant to the previous subsection, the Director of Community
Development shall decide,within thirty(30)days, if the circumstances involving the particular lot
and surrounding Sidewalk District reasonably require a return of the escrowed funds.The owner
of the lot may appeal the decision of the Director of Community Development by filing a written
objection,explaining the owner's argument and requesting for a hearing before the City Council,
with the City Secretary not later than ten (10) days after the Director of Community
Development's decision.After hearing the lot owner's objections, City Council may either refund
the escrowed money or deny the refund and order the funds to be used for future sidewalk
construction on that lot or in that sidewalk district.

1. The developer shall accept and be responsible for all runoff from properties upstream of the proposed
development. The proposed improvements shall be designed for fully developed conditions.
2. Where a drainage study indicates that additional runoff from the developing property will overload
downstream drainage facilities and result in hazardous conditions, the City may withhold approval of
the development until appropriate provisions have been made. These provisions shall include any
drainage design or construction plans necessary to accommodate the off-site drainage problem.
Section 9.16 Street Improvement Requirements
A. General Requirement— The developer shall construct, at his expense, street facilities necessary for the
proper development of the subdivision. The street system shall provide access to every lot in the
subdivision and be designed and constructed in accordance with the criteria contained in this Land

Chapter 9—Subdivision Design&Public Facilities Page 9-7
Exhibit "A"
Colleyville, Texas,Land Development Code
and utility improvements in-lieu of the actual construction of said facilities. Any escrow,without interest,
shall be applied against any assessment for improvements levied on such property, but shall not be
deemed to release such property from liability for any future costs assessed which exceed the escrow.
3. One and Two Lot Residential Subdivisions—If a proposed residential subdivision contains only one or
two lots and the developer does not own any contiguous property, in lieu of actual construction, the
developer shall pay the applicable perimeter street costs in accordance with the General Infrastructure
Policy contained elsewhere in this Land Development Code for the initial one hundred feet of street
frontage. The applicable perimeter street costs shall be reduced 0.2% per linear foot of frontage in
excess of one hundred feet, not to exceed fifty percent of the applicable additional street frontage.
Exemption: A lot platted under this Section that contains an existing single-family dwelling at the time
a subdivision plat application is filed with the City and the lot is situated within a zoning district that
allows single-family residential uses, said lot shall have an automatic exemption from the perimeter
street costs, provided that existing perimeter street facilities are sufficient to assure the safe, effective
and orderly movement of traffic in and about the subdivision and utility services are adequate to serve
the development. The following notation shall be placed on the plat: `Any future divisions of these lots
will require full compliance with the unimproved street requirements applicable at the time of any
subsequent re-platting."
Section 9.17 Street Design Criteria
A. Street Functional Classification — All streets shall be designed in accordance with the functional
classification shown on the most recent version of the Master Thoroughfare Plan and the following:
Functional Classification of Streets
Street
Classification Functions-Uses
Carries traffic from residential and commercial areas to collector streets and
Local interconnects individual sites. Local streets carry light traffic volumes and trips are of a
short duration.
Collector Carries traffic from local streets to arterial streets. Uses served would include medium
and high density residential, limited commercial facilities, elementary schools, some
Major small offices and as direct access within industrial parks. Collector streets also carry
Minor heavy traffic to major commercial and industrial facilities from arterial streets. Uses
would include office parks,industrial parks,and community level commercial facilities.
The main function of an arterial is to carry traffic from on urban area to another. The
Arterial arterial streets serve the major activity centers of urbanized areas. An arterial street is
Major used for longer urban trips and carries a high portion of the total traffic with a minimum
Minor of mileage.
-- r
B. Street Design
1. In-General— Streets shall be designed with due regard to topography, with due consideration of the
abutting uses, and the anticipated destination of traffic and traffic volumes at full development of the
neighborhood. Where necessary to prevent traffic congestion and to ease the movement of vehicles
to and from principal traffic generators, additional right-of-way width or other special design shall be
provided. Where topographical conditions make other treatment necessary to secure the best overall
design, these standards may be modified by the Director of Public Works or designee..
2. Street Continuity—The street layout shall provide for the continuation of the collector street system as
shown on the Master Thoroughfare Plan. Streets shall provide connection to streets in adjacent
subdivisions,but local streets shall be designed so as to discourage use by through traffic and to require
the minimum number of streets necessary for convenient and safe access to property.
Chapter 9—Subdivision Design&Public Facilities Page 9-8
Exhibit "A"
Colleyville, Texas,Land Development Code
3. Curvilinear Streets Encouraged-The developer is encouraged to consider curvilinear, cul-de-sac,and
loop street designs where such use would result in a more functional layout and not necessarily adhere
to a rigid rectangular street pattern.
4. Right-of-way Widths— Every subdivision plat shall dedicate sufficient right-of-way to comply with the
requirements of the Master Thoroughfare Plan. The right-of-way widths shall be designed for the
intended use and anticipated traffic volume at optimum development of the area served. Additional
right-of-way may be required at street intersections and to provide for left and right turn lanes at high-
volume intersections.
5. Cul-de-sac Lengths — No street shall be designed as a permanent dead-end street, but shall be
designed to incorporate a cul-de-sac which complies with this Section. (0-00-1261/12-19-00)
a. Diameter—A cul-de-sac street shall be provided at the closed end with a minimum property line
right-of-way diameter of one hundred feet, and a pavement turn-around with a minimum outside
diameter of eighty feet(80'). (0-00-1261/12-19-00)
b. Length—No cul-de-sac street shall exceed six hundred feet(600')in length, unless additional right-
of-way width and additional pavement width are provided as required in this Section. Furthermore,
no cul-de-sac street shall exceed the maximum length of one-thousand two hundred feet(1,200').
For purpose of this regulation,cul-de-sac length shall be measured along the centerline of the cul-
de-sac from the intersecting street right-of-way line to the center point of the cul-de-sac. (0-00-1261
/12-19-00)
c. Width—A cul-de-sac street shall have a minimum right-of-way width of fifty feet(50')and a minimum
pavement width of thirty-one feet(31'), back-to-back of curb. However, a cul-de-sac street which
exceeds six-hundred feet (600') in length shall have a minimum right-of-way width of fifty-six feet
(56')and minimum pavement width of thirty-six feet(36'), back-to-back of curb. (0-00-1261/12-19-00)
d. Maximum Number of Lots — The maximum number of single-family lots served on a cul-de-sac
street shall be as shown in the following table: (0-00-1261/12-19-00)

PUD-R 12
e. Temporary Turn-Around—A temporary turn-around is required when a street is temporarily dead-
ended and is longer than one-hundred and fifty(150)feet, as measured from the intersecting street
right-of-way line. The temporary turn-around shall be within a temporary easement and constructed
of asphalt or concrete. (0-00-1261/12-19-00)
6. Temporary Dead-End Streets-Temporary dead-end streets shall have provision for future extension
of the street and utilities and, if a temporary cul-de-sac is utilized, a reversionary right to the land
abutting the turnaround for excess right-of-way shall be provided.
7. Stub-outs for Future Extensions- Permanent dead-end roads shall not be allowed. The street layout
shall be extended to the tract boundary to provide for future access into adjoining tracts to assure
adequate neighborhood circulation, unless prevented by topography or other physical conditions, or
unless, the Planning and Zoning Commission determines that the extension is neither necessary for

Exhibit "A"
Colleyville, Texas,Land Development Code
future development of adjacent tracts. In general, these extensions should be not more than one
thousand (1,000)feet apart.
8. Pavement Required- All street surfaces within or abutting the proposed subdivision shall be paved,
with curbs and gutters installed, and constructed in accordance with the standards and specifications
contained elsewhere in this Land Development Code.
9. Frontage Access Road-Where a subdivision abuts or contains an existing or proposed collector street
or railroad right-of-way or abuts a commercial or industrial land use, the City may require a frontage
street approximately parallel to and on each side of such right-of-way to separate through and local
traffic, or reverse frontage with screen planting contained in a non-access reservation along the rear
property line, deep lots with rear service alleys, or equivalent treatment as may be necessary for
adequate protection of residential properties.
10. Half Streets- Half streets shall be prohibited, except where essential to the reasonable development
of the subdivision in conformity with the other requirements of these regulations, and where the
Planning and Zoning Commission finds it will be practicable to require the dedication of the other half
when the adjoining land is subdivided,the other half of the street shall be platted within such tract.
11. Number of Subdivision Entryways— Every subdivision shall be designed to provide sufficient access
into the development to accommodate anticipated traffic demands and to provide for emergency public
services using the criteria contained in this Section. (0-01-1280/08-08-01)
a. Where a proposed subdivision, or cul-de-sac street, contains more than twelve (12) lots, the
development shall provide for two entryways as follows:
i. The development shall provide one street entryway and one emergency access easement.
The emergency access easement shall be located on an adjacent or opposite side of the
subdivision from the main entryway. The widths of the right-of-way and driving surfaces of the
street entryway and the emergency access easement shall be in accordance with the standards
contained elsewhere in this Land Development Code, or
ii. The development shall provide two street entryways separated not less than one-hundred
feet between the centerlines of the driving surfaces. The widths of the right-of-way and
driving surfaces of the two entryways shall be in accordance with the standards contained
elsewhere in this Land Development Code, or
iii. The development shall provide a divided entryway and one emergency access easement. The
driving surfaces of the divided entryway shall be separated by a median not less than ten (10)
feet in width and provide for one-way traffic. The widths of the right-of-way and driving surfaces
of the divided entryway shall be in accordance with the standards contained elsewhere in this
Land Development Code. The emergency access easement shall be located on an adjacent
or opposite side of the subdivision from the main entryway and be constructed in accordance
with the standards contained elsewhere in this Land Development Code.
b. If it is physically impractical or otherwise impossible to provide two entryways or to incorporate an
emergency access easement into the development in accordance with the above stated
requirements,the following alternative may be considered by the approving body:
i. A single pavement width of forty-one (41) feet shall be constructed. Said pavement shall
extend back from the intersecting street right-of-way a minimum distance of one-hundred(100')
feet. All residences within the subdivision shall contain automatic fire-sprinkler systems.
c. If it is physically impractical or otherwise impossible to comply with the above-stated requirements,
an alternative design may be submitted to the City Council for consideration. The approving body
Chapter 9—Subdivision Design&Public Facilities Page 9-10
Exhibit "A"
Coffeyville, Texas,Land Development Code
may approve the alternate design if it finds that the above-state requirements can not be satisfied
and that all efforts have been made by the developer to comply with said requirements.
12. Reverse Curves- Between reverse curves there shall be a tangent section of centerline not less than
one hundred feet(100') long.
C. Intersections
1. Streets shall be laid out so as to intersect as nearly as possible at right angles.A proposed intersection
of two(2) new streets at an angle of less than seventy-five(75)degrees shall not be acceptable.
2. Proposed new intersections along one side of an existing street shall, wherever practicable, coincide
with any existing intersections on the opposite side of such street Not more than two (2) streets shall
intersect at any one point unless specifically approved by the City.
3. Street jogs with centerline offsets of less than one hundred thirty-five(135)feet shall not be permitted.
4. Local streets intersecting a collector street or larger shall have a tangent section of centerline at least
fifty (50) feet in length measured from the right-of-way line of the collector street; however, no such
tangent is required when the minor street curve has a centerline radius greater than four hundred(400)
feet with the center located on the collector street right-of-way line.
5. At local street intersections, the property line corner shall be rounded by an arc having a radius of
twelve (12) feet. This radius shall be increased when the smallest angle of intersection is less than
eighty(80)degrees. At intersections of streets with major and collector streets the property line corners
shall be rounded by an arc having a radius of twenty-five (25) feet. The Director of Public Works or
designee may approve comparable cut-offs or cords in place of rounded corners.
6. Where practical, spacing of intersections along collector streets shall be at least 500 feet apart.
D. Easements—Easements for drainage and utility construction, service, and maintenance shall be provided
in locations approved by the City and affected utilities according to the following standards:
1. Easement for the use of public utilities of not less than seven and one-half(7.5')feet in width shall be
provided on each lot and extend along the entire length of the rear property line. Easements shall

Section 9.18 Traffic Impact Analysis
When a proposed subdivision plat is estimated to generate more than 1,000 vehicle trips per day, a traffic
impact analysis shall be required with the earliest submittal of a plat application. The traffic impact analysis
shall be prepared in accordance with the requirements of the Director of Public Works or designee. The purpose
of the traffic impact analysis is to determine the need for traffic mitigation measures which may include, but are
not limited to,dedication of additional right-of-way,construction of turning lanes,or construction of traffic control
facilities. This requirement may be waived when a traffic impact analysis was submitted at the time the current
zoning was adopted and the traffic impact analysis is less than one year old. Any mitigating measures required
shall be the responsibility of the developer, unless a cost-sharing agreement is approved by the City.

A. General Sidewalk Requirement
1. Sidewalks shall be constructed prior to completion of any primary structure for all lots that: (1)
are required as part of a Planned Unit Development or Special use Permit; or; (2) front on a
new street dedicated in conjunction with a subdivision plan; or, (3) front on an existing City
Street. Other than properties zoned as Planned Unit Developments or containing special Use
Permits with specific sidewalk provisions, sidewalks shall be required to be constructed prior
to the final inspection.Any variance to the sidewalk construction requirements described above
shall be considered by the City Council.
2. The sidewalks shall be constructed adjacent to and within the public street right-of-way and
include curb ramps where applicable. Where no public right-of-way exists, the sidewalk shall
be located within a public access easement that provides accommodation of the future street
right-of-way dedication. When a subdivision is proposed with a masonry or other permanent
perimeter screening wall adjacent to a street, the sidewalk shall be constructed by the
developer at the same time as the screening wall. All sidewalks shall conform to the standards
and specifications contained in this Land Development Code.
3. When circumstances exist wherein it is not practical to construct a sidewalk, the developer
maybe afforded the opportunity to escrow funds in an amount sufficient to pay for the
construction of a sidewalk at some future date.

construct a sidewalk or pay the required escrow amount.
B. Trails System Sidewalks — When a proposed sidewalk coincides with the general location of a future
sidewalk shown in the most recently approved Colleyville Trails System Plan, the sidewalk shall be
constructed in accordance with the design standards for a trails system sidewalk. The standards and
specifications for a trails system sidewalk are contained elsewhere in this Land Development Code. The
developer shall be required to provide additional street right-of-way dedication or a public access easement
of sufficient width to accommodate the trails system sidewalk. Where the trails system sidewalk will be
located at the rear or to the side of a lot, such as within a green-belt or similar open space, the developer
shall provide sufficient right-of-way or public access easement to accommodate the sidewalk.
Section 9.20 Street Lighting
A. General Requirements—The developer shall be required to install, at no cost to the City, a street lighting
