Thoroughfare Plan
1.0 INTRODUCTION
1.1 Background
In 1992, the Town of Westlake adopted a Thoroughfare Plan as a component of a Comprehensive
Plan. This Thoroughfare Plan was composed of a set of Policies, a Conceptual Thoroughfare Map,
and a set of Conceptual Roadway Sections. Since that time, an ordinance concerning driveway
access and design has been approved and there is a need to update the functional classification
designations of the roadway system to conform to current standard nomenclature and application to
the driveway access and design ordinance. This plan serves as an update to the 1992 plan, and
replaces it as the Town's official thoroughfare plan component of the Comprehensive Plan.
1.2 Plan Purpose
The purpose of the Thoroughfare Plan, as a component of the Comprehensive Plan, is to provide
residents, employees and visitors to Westlake with convenient vehicular and pedestrian access and
roadway circulation. It is further intended to reinforce the rural and recreational character of the
Town, minimize traffic congestion, and be environmentally sensitive in terms of reducing air
pollution and storm water runoff. It is also intended to be compatible with the specific thoroughfare
plans of adjacent cities and the general roadway system of the total urbanized area.
The Plan contains a et of goals and policies and a map which are intended to provide guidance for
the planning and design of multi-modal facilities in Westlake. Roadway alignments depicted within
are general in nature. Detailed design and construction standards for roadways can be found in the
Town's Engineering Standards.

Town of Westlake
2.0 INVENTORY AND ANALYSIS
2.1 Function of Thoroughfare Planning
The function of the Thoroughfare Plan is to provide a guide for determining future roadway
requirements for the Town. The Plan is developed to support the Town's land use plan by providing
adequate capacity to move people,goods, and services efficiently. It will allow the Town to acquire
needed right-of-way in advance of or as new development occurs.
The plan should be flexible and should be reviewed on a regular basis to incorporate changes in local
conditions. The plan is a guide that indicates roadway capacity needs in response to planned land
uses in an area and serves as a basis for subdivision requirements. In developed sections of the
Town,the Thoroughfare Plan provides guidance for upgrading and/or protecting the integrity and
character of existing thoroughfares.
2.2 Thoroughfare Planning Process
The process of developing a thoroughfare plan requires the consideration of elements that affect
travel demands, movement and access requirements, and physical constraints to roadway
construction. In addition, the plan should further community objectives for the character of
Westlake. The first consideration in developing a thoroughfare plan is the Town's land use plan.
The type of land uses that are existing or planned for an area help to decide the appropriate roadway
capacity and access needs for that area. A densely developed commercial area will require higher
capacity roadways and intersections than a low density residential area.
The next consideration is balancing the movement and access functions of the thoroughfare system.
Roadways serve two competing functions, the movement of traffic, and access to properties. This
competition exists as ingress and egress maneuvers from local properties impede the movement of
traffic on major roadways, and as high traffic volumes make turning movements into and out of
driveways difficult. Structuring a thoroughfare plan such that these two competing functions occur
on separate portions of the system is a primary goal of thoroughfare planning.
Physical constraints to roadway construction such as drainage areas, topography, vegetation, and
existing development are considered. Efforts are made to cross, or avoid these constraints in a
logical manner that will minimize topographical changes and construction costs while maintaining
mature stands of trees and efficient operations. In addition, it is important to lay out roadways that
will open key views and vistas within the Town.
Finally, community objectives for maintaining a rural character for the Town while accommodating
development, lielp to further determine roadway patterns, access characteristics and the design of
roadway corridors.

Town of Westlake
2.3 Existing Conditions in Westlake
The system of streets and highways in the Town of Westlake is generally comprised of rural asphalt
roadways constructed by Tarrant and Denton Counties. The exceptions are(1)the sections of U.S.
377, S.H. 114 and S.H. 170 that have been upgraded to freeway standards and (2) the sections of
Kirkwood Boulevard and Sam School Road constructed to improved standards in the Solana
development.
2.4 Thoroughfare Plans of Adjacent Cities
In the interest of showing the relationship between the proposed Town of Westlake Thoroughfare
Plan and the thoroughfare plans in the adjacent cities, information on the plans for the cities
surrounding the Town has been obtained and is presented in Figure 1 (see p. 4). As shown, all
thoroughfares that extend to the boundaries of the Town link directly to a similar roadway cross-
section in an adjacent municipality.

3.0 TRANSPORTATION SYSTEM POLICIES
The following goals and policies have been developed to provide guidance and direction in the
planning,design,implementation,maintenance and operation of a multi-modal transportation system
for the Town of Westlake. These goals and policies should be supported with specific actions by
the Town to assure that the desired levels of mobility, safety,and land use compatibility are attained.
Goal 1: Develop a road system within Westlake that works with development standards
to create a rural experience for the driver and reinforces a sense of community
in Westlake.
Policy 1.1 Develop roadways, where possible, that:
• Use natural swales for drainage
• Are constructed of high quality.concrete or asphalt construction, without
curbs and gutters.
• Take advantage of views to hills, valleys,trees, and water,
• Are bordered by densely landscaped thickets,
Policy 1.2 Avoid frequent driveways or intersections along major and minor arterials.
Policy 1.3 'nary horizontal and vertical alignment of directional travel lanes on major arterials.
Goal 2: Develop roadways and circulation routes to take advantage of, and work with,
the natural topography to enhance the community's rural character and design.
Policy 2.1 Locate and design all roadways to minimize grading to both create the roadway and
to create usable building sites.
Policy 2.2 Major arterials should be laid out to follow topographic contours and to take
advantage of views and vistas to landmark development or natural features such as
hills, trees and water bodies,
Policy 2.3 Locate and design local roadways to:
• Avoid straight horizontal alignments
• Preserve specimen trees and groves of trees
• Create local views and vistas that reinforce the community's rural character
Goal 3; Ensure that the Westlake thoroughfare and circulation system fits into regional
circulation systems.
Policy 3.1 Locate and design thoroughfares to facilitate regional circulation, but discourage
"cut through" traffic in the Town.

Town of Westlake
Goal 4: Ensure a balanced relationship between land use development and the
transportation system.
Policy 4.1 Develop administrative procedures and responsibilities for the preparation, review
and approval of land use-related transportation plans and development traffic impact
studies.
Policy 4.2 Maintain a Master Thoroughfare Plan coordinated with land use development
considerations represented in the Comprehensive Plan which permits the following:
• Right-of-way acquisition necessary to improve intersection capacity and
thoroughfare continuity.
• Right-of-way dedications as specified by the Master Thoroughfare Plan.
• Intersection designs and right-of-way alignments where possible as part of
the Master Thoroughfare Plan.
• Dedication of street system rights-of-way in those areas of the community
that are undeveloped.
Policy 4.3 Coordinate local, state and federal street and highway improvement project planning
with existing and expected land uses.
Policy 4.4 Locate and design thoroughfares to provide a high level of design amenity and
neighborhood preservation, including the consideration of neighborhood traffic
management programs.
Policy 4.5 Develop and implement a roadway functional classification system which provides
for a range of traffic flow functions from providing mobility for through traffic to
providing access to adjacent properties.
Goal 5: Ensure the development, maintenance and operation of a safe, efficient and
effective transportation system to serve the Town.
Policy 5.1 Develop and maintain a transportation planning process which addresses long range
needs but emphasizes short and mid-range problem solving.
Policy 5.2 Develop and maintain programs and funding strategies to implement transportation
improvements, ensuring adequate capacity at the least cost to the Town without
compromising service, delivery, or quality.
Policy 5.3 Develop, maintain, and operate a street and highway system which will meet the
existing and future travel needs of the Town in terms of safety and capacity.
Policy 5.4 Investigate opportunities to provide a fiscally responsible transit system which gives
consideration to journey-to-work trips, the needs of transit dependent persons, and
Westlake Thoroughfare'Plan Page 6

opportunities for inter-modal transfer.
4.0 THOROUGHFARE SYSTEM
The Thoroughfare Plan proposed for the Town of Westlake is based on a system of functionally
classified roadways. These functional classifications are intended to reflect the role or function of
each roadway within the overall thoroughfare system.
4.1 Roadway Functional Classification System
The functional classifications describe each roadway's function and reflect a set of characteristics
common to all roadways within each classification. Functions range from providing mobility for
through traffic and major traffic flows to providing access to specific properties. Characteristics
unique to each classification include the degree of continuity, general capacity, and traffic control
characteristics. Figure 2 illustrates the relative roles of each classification to achieve its intended
function,

Westlake Thoroughfare Plan Page 7
Town of Westlake
The vehicular road system is hierarchial in nature and includes freeways, major and minor
arterials, major and minor collectors and local streets. Freeways, or expressways, are high
capacity facilities with controlled access and are intended to carry high volumes of longer distance
trips. They are a high capacity regional supplement to the arterial system. Arterials are used to
move large volumes of through traffic at relatively high speeds throughout the community. Arterial
streets are more or less continuous throughout the community and their primary function is to
provide movement of traffic for arterials. Property access is a low priority function. The Collector
system is used to carry moderate amounts of traffic and provide limited access to adjacent properties.
Their function is to collect and distribute traffic to and from arterial and local streets. Local streets
are used for low volume, low speed traffic movements. Their function is to primarily provide direct
access to adjacent properties.
Neighborhoods should be developed between arterial streets so that through traffic is routed
around—not through—these areas. Collectors should penetrate the neighborhoods to collect and
distribute traffic but not provide convenient, cut-through routes. Land use planning efforts should
attempt to encourage compatible land uses adjacent to streets. Commercial activities should be
developed in such a way that the primary mobility function of arterials are not degraded through
access management. Wherever concentrations of traffic occur on collector streets, consideration
should be given to not allowing houses to front on the street. Good subdivision designs can allow
ample lot yields while orienting houses to local streets and not to collectors.
Table 1. describes the most important characteristics of the roadway functional classifications. The
arterial classification contained herein includes major arterial and minor arterial. The following
sections describe the major features of the proposed plan.
Figure 3 illustrates the Thoroughfare Plan for the Town of Westlake. The Plan recognizes the
following classifications of public streets: Freeway,Major Boulevard Arterial,Major Arterial,Major
Collector, Minor Collector and Local. The following briefly defines each classification in the
Thoroughfare Plan:
• Freeway- as designed,built, and maintained by the State of Texas. Existing examples
are Northwest Parkway, State Highway 170 and US 377.
• Major Boulevard Arterial, six (6) lane divided - an existing example is Kirkwood
Boulevard. Rights-of-way average 165 feet wide but are quite variable(160 to 170 feet)
and wide; minimum right-of-way is 130 feet. The median should vary from 20 to 60
feet. Each set of three lanes (referred to as a lane bundle) is laid out with its own
centerline, independent of the other lane bundle, to allow maximum scenic beauty and
variety. The median should be heavily landscaped as per the Town's Unified
Development Code. Median crossings should be within five (5) degrees of being
perpendicular to each lane bundle centerline.

• Major Arterial,six(6) lane divided-right-of-way varies between 130 to 165 feet with
a median width of 20 to 55 feet to allow for variations in the centerline of each lane
bundle to maximize scenic beauty and variety. Examples (not in Westlake) of the
general concept of this classification are Carroll Blvd. in Denton, or Forest Lane in
Dallas. The median should be landscaped as per the Town's Unified Development Code.
• Minor Arterial, four(4) lane divided - right-of-way is 120 feet with a median width
of 24 to 30 feet. The intended purpose of a larger median width is to accommodate the
potential need for additional turn lanes at intersections with other arterial streets. The
median should be landscaped as per the Town's Unified Development Code.
• Major Collector,four(4) lane divided - right-of-way width is 106 feet with a median
of 24 feet. The median should be landscaped as per the Town's Unified Development
Code,
• Minor Collector, two (2) lane - right-of-way width is 90 feet.
• Local, two (2) lane - right-of-way width is 60 feet. Roadway cross-section varies
depending if curbs are present or not. In a curbed section, the roadway width is 30 feet
and in an uncurbed section, the width is 24 feet.
In order to incorporate topographic features within Westlake as well as hike-and-bike trails adjacent
to roadways, right-of-way may vary by an additional 10 feet as identified in the Typical Roadway
Landscape Edge. A graphic illustration depicting the recommended roadway cross sections is shown
in Figure 3. Outside of the roadway edge, roadway cross-sections vary and is dependent upon the
location of utilities.
