SOUTHLAKE 2035 PLAN: Future Land Use Plan
The site is designated “Mixed Use”.
Purpose and Definition: To provide an option for large-scale, master-
planned, mixed use developments that combine land uses such as office
facilities, shopping, dining, parks, and residential uses. The range of
activities permitted, the diverse natural features, and the varying proximity
to thoroughfares of areas in the Mixed Use category necessitates
comprehensively planned and coordinated development. New
development must be compatible with and not intrusive to existing
development. Further, special attention should be placed on the design
and transition between different uses. Typically, the Mixed Use
designation is intended for medium- to higher-intensity office buildings,
hotels, commercial activities, retail centers, and residential uses.
Nuisance-free, wholly enclosed light manufacturing and assembly uses

that have no outdoor storage are permitted if designed to be compatible
with adjacent uses. Other suitable activities are those permitted in the
Public Parks/Open Space, Public/Semi-Public, Low Density Residential,
Medium Density Residential, Retail Commercial, and Office Commercial
categories.
Crooked/Kimball Small Area Plan 2030
The property is also included in the 82-acre Crooked/Kimball Small Area
Plan. The Future Land Use designation was changed from Low Density
Residential to Mixed Use in 2012 as a result of the recommendations in
the plan. The proposed development area is located within the 75-LDN
overlay for the DFW airport and prohibits residential uses.
2035 Southlake Plan
The Southeast Sector Plan from the 2035 Southlake Plan for the S.
Nolen Drive/Crooked Lane recommendations:
• Provide access or street/cul-de-sac from Village Center to help
preserve the rural nature of Crooked Lane.
• Development should occur in a manner that preserves and
integrates the natural tree cover into the area through the use of
open space and creative design.
• Preserve trees adjacent to Crooked Lane to maintain the
character of the roadway.
• Future development on these properties should be approved in
a manner that is sensitive to potential impacts on adjacent
residential areas, particularly as related to noise, traffic, building
heights, lighting and views.
Mobility & Master Thoroughfare Plan
The Mobility and Master Thoroughfare Plan shows S. Nolen Drive. to be
a 3-lane undivided arterial with 70-foot of right of way. The future Village
Center Drive location will be north of the property and connect to S. Nolen
Drive and S. Kimball Avenue; it is planned as a 2-lane undivided collector
with 60’ of right of way. The property will not have direct access to
Crooked Lane, a 2-lane local street with a 60-foot right-of-way.
Pathways Master Plan & Sidewalk Plan
There are currently no sidewalks along Crooked Lane or S. Nolen Drive
of the subject property. The Pathways Master Plan indicates a less that
8-foot wide sidewalk on both the west side of S. Nolen Drive and the west
side of Crooked Lane. The applicant is providing a 5-foot sidewalk along
the west side of S. Nolen Drive and a 6-foot sidewalk on the west side of
Crooked Lane.
TRANSPORTATION

developments to S. Kimball Drive.
TREE PRESERVATION: The site is subject to the City’s Tree Preservation Ordinance No. 585-E
Under traditional zoning the proposed preservation of the existing tree
cover would not comply with the Existing Tree Cover Preservation
Requirements of the Tree Preservation Ordinance 585-E. There is 42.7%
of existing tree cover across the property and 50% of the existing tree
cover would be required to be preserved. 74.4% of the existing tree
canopy cover is proposed to be removed and 25.6% proposed to be
preserved.
UTILITIES: The water line access to the site is located along the west side of S. Nolen
Drive with an 8-inch water line, a 6-inch water line on the west side of
Crooked Lane, and two (2) 8-inch water lines at the Pinnacle Point
development to the west of the property.
The property has access to an 8-inch sewer line along the west side of S.
Nolen Drive and an 8-inch sewer connection at the Kimball Heights
development to the west.
DRAINAGE: The site drains from the west to the east and southeast towards S. Nolen
Drive and Crooked Lane.
The proposed drainage improvements include a detention pond at the
south end of the property in Phase 1 and an underground drainage pond
(structure) under the parking lot located in the southeast corner of Phase
2. These structures will drain by underground pipe northeast to an existing
36-inch drainage pipe located at the southwest corner of the S. Nolen
Drive and Crooked Land intersection. This structure will carry the water
under S. Nolen Drive northeast to an existing drainage channel.
CITIZEN INPUT: The following meetings were held to discuss the development:
A 2035 Corridor Planning Committee meeting was held on June 24, 2020.
The report is provided in the packet.
A SPIN meeting was held on September 22, 2020. The meeting report is

each taxing unit with jurisdiction of the real property, indicating that no delinquent taxes are owed
and that taxes for the current year have been paid. After September 1st, a certificate showing
that the taxes for that year are paid, but that the taxes for the upcoming year have yet to
be calculated is required. (House Bills 1563 & 3101). A copy of this information may be
