Pecan Lake — Stagecoach/Dodd — Westwood Neighborhood Action Plan
Existing Conditions: Update 2007
Introduction
The City of Little Rock Planning and Development Department was contacted by the
Westwood Neighborhood Association to update the Neighborhood Action Plan from
April 2000. The Westwood Neighborhood Association worked together to propose
several changes to their original goals and objectives. City staff contacted the Pecan
Lake Property Owners Association, the Stagecoach Dodd Neighborhood Association,
and the Tall Timbers Home Owners Association, but none of these surrounding
associations expressed an interest in updating their portion of the plan. City staff
conducted background research regarding the changes to this area since 2000. The
result of that research is contained in the following report.
Neighborhood Action Plan Boundaries
The boundaries of the study are the same as the original Pecan Lake-
Stagecoach/Dodd-Westwood boundaries defined in the Neighborhood Action Plan of
2000. The plan area boundaries are: Colonel Glenn Road to the north, Interstate 430
to the west, Fourche Creek to the south and east.
Demographics Update
The population of this area has increased significantly since the 1990 Census. In 1990,
there were approximately 3,300 people living in this region. According to the 2000
Census, that figure had increased by 45% to 5,979. 52% of the population in this area
is female and 48% is male. According to the 2000 Census, the area is comprised of
48% Black, 45% White, 4% Hispanic and 3% other. This is a change from 1990
Census data, which showed 58% White, 41% Black, 1% other, and 0% Hispanic. While
Census data is not yet available for the years past 2000, the population for this area can
be assumed to still be increasing rapidly due to the amount of new single-family
subdivisions in the area.

As the chart above shows, the plan area is still predominately Single Family residential,
but the amount of Park/Open Space has increased significantly since 2000. This
increase is a direct result of Ordinance 18,526. This Ordinance was signed by the City
Board of Directors on July 17, 2001 to amend eleven areas around the city to recognize
existing uses of city parks, museums, etc. in conjunction with the adoption of the new
Parks Master Plan. The Jack Stephens Golf facility was amended from Low Density
Residential on the Future Land Use Plan to Park/Open Space.
Two other sites within the plan area were amended since 2000. The Mixed Use and
Suburban Office at the southeast corner of Interstate 430 and Colonel Glenn Road was
amended to Commercial and Office for office, warehouse, and commercial uses by
Ordinance 18,411 on January 16, 2004. The other amendment took place on the south
side of Colonel Glenn between Cobb and Walker Streets. Ordinance 19,044 was
signed on January 20, 2004 to change this area from Mixed Use to Commercial for
future development.

The neighborhoods covered by this plan are zoned primarily for single-family residential
development. There are currently 3194 acres of land in this plan area zoned for some
form of residential. This is 87% of the total land. The remaining area is zoned
Commercial (214 acres), Industrial (188 acres), Office (88 acres), and Open Space (12
acres). These percentages have not changed much since 2000, but there have been
28 separate zoning changes within this area. Six of these changes were for setback or
sign variances. Five were for Conditional Use Permits and one was for a Special Use
Permit to allow a daycare in R-2 zoning. Two were for wireless communication facilities
in this area, and fourteen were for rezoning or planned developments.
Housing Conditions Update
There have been 257 new houses built in this area since 2000. Some of the
subdivisions include: Tall Timber West, Greenwood Acres, Woodridge Estates, and
Pecan Lake. There have been 20 permits issued since 2000 for additions to single-
family residences. There have been 43 permits issued since 2000 for renovations to
single-family residences in this area. More subdivisions are already being planned for
this area.
Circulation/Infrastructure Update
Many improvements have been made to the infrastructure within this neighborhood
plan. One of the most common concerns in 2000 was Asher Avenue. The completion
of the Arkansas Highway Department project to widen Colonel Glenn/Asher Avenue to a
five lane arterial from University to Stagecoach has alleviated most of these concerns.
Also of note, on June 3, 2003 the City of Little Rock Board of Directors passed
Resolution 11,522 to officially change the name of Asher Avenue to Colonel Glenn from
University Avenue west to Stagecoach Road. This change came after the Asher
Avenue Planning Committee requested the change to the Planning Commission with a
Update 2007 - 4 -
signed petition with more than 50% of the individuals and businesses in support of the
name change.
Many of the neighborhood action plan action statements have been completed by
Public Works since 2000. The drain on Mellwood Drive was a problem for the
Westwood area. There had been street flooding & structural flooding to homes east
adjacent to the ditch, due to an undersized structure. This drain was improved in
response to the Neighborhood Action Plan request. Other drainage improvements were
made on Shackleford south of Colonel Glenn. The Public Works department replaced
aging metal pip with 80’ pf 10’X5’ concrete box culverts.
Many street signals were either added or replaced in this area: Colonel Glenn at I-430,
Colonel Glenn at Shackleford, Stagecoach at I-430, Timberland/Tall Timber at
Stagecoach, Western Hills at Colonel Glenn, Colonel Glenn at Fire Station #14, and
First Tee Drive at University Avenue.
Other infrastructure improvements since 2000 include:
• Sidewalks at Western Hills Elementary
• Asphalt overlay on Herndon/McPherson
• Road widening on Colonel Glenn at the southbound access road to I-430
• Road widening of Colonel Glenn from University Avenue to Stagecoach to a five
lane arterial (AHTD)
• Asphalt overlay on Lanehart Road
Parks Update
There have been many significant improvements made in this area by the Parks and
Recreation department:
• Hindman Golf Course Bridge $725,000
• Hindman Cart Path $65,875
• Hindman Electrical Upgrade $5,000
• Hindman Tee Signage $8,845
• Completion of The First Tee golf course
• The First Tee Fence $9,200
No new parks or new programs were added.
Police Update
On February 5, 2007, the Northwest Patrol Division was responsible for creating a plan
of action to handle the increased number of burglaries (commercial and residential)
throughout the Northwest area. The plan is known as “Operation Phoenix” and involves
personnel from the Detective Division, Special Investigations Division and Northwest
Mobile Squad. Officers involved with this operation exchange information involving
activity occurring in their respective areas and meeting every Monday to discuss tactics
and trends of the operation. This operation is ongoing and will continue until the Chief
Update 2007 - 5 -
of Police issues further direction. While Operation Phoenix is targeting daytime crimes,
Operation Quiet Night targets violent crimes that occur during the nighttime hours.
Operation Quiet Night consists of the Special Investigations Unit, SWAT Unit, Special
Operations Mobile Unit, and the Patrol Divisions.
Since 1994, the Little Rock Police Department implemented the Community Oriented
Policing (COP) Philosophy to facilitate a better partnership between the community and
police. This concept integrated officers into neighborhood alert centers, placing them in
a position to deal with citizen issues more directly and foster cooperation between other
community resources. In the fall of 2004, the Northwest Patrol Division re-organized it’s
COP program, which allowed them to address more citizen concerns and better utilize
the division’s resources. These officers are now known as the Northwest Mobile Unit
and under the supervision of Sergeant Andre Dyer. His squad has been responsible for
a significant decrease in the number of crimes in the Northwest area and actively patrol
the Westwood area when problems are identified or reported.
Updated Goals
In July 2007, City of Little Rock Staff made an effort to contact the Pecan Lake Property
Owners Association, the Stagecoach-Dodd Neighborhood Association, the Tall Timber
Home Owners Association and the Westwood Neighborhood Association. Westwood
was the only area that submitted any edits. The Westwood Neighborhood Association
worked together to amend and revise their existing action statements. Several action
statements were removed because they have been completed since the last writing.
Other action statements were added to reinforce the existing goals. Finally, some were
simply re-worded to give better clarity or to address minor issues such as street name
changes. The updated goals have been included in this report.

committee is dedicated to improving the school experience of students in the area, as
well as increasing interaction between residents and the schools. Since the Little Rock
School District has resumed assigning
students to neighborhood schools,
Westwood students attend Western
Hills Elementary, Southwest Middle,

Westwood
Traffic and Transportation
The most traffic and transportation problems in the Westwood area are caused by the
condition and narrowness of Colonel Glenn Road. Most of the participants’ concerns
(i.e. left turn lanes along Colonel Glenn) were alleviated when the Highway Department
completed its project on Colonel Glenn.
Goal: Ensure safe and efficient movement of traffic in, around and through the
neighborhood.
Objective #1:
Install street lighting, where needed, for safety.
Proposed Action (Ranked in priority order):
• Improve and add additional street lighting on Colonel Glenn from University
Avenue to Stagecoach Road intersection

humps, traffic circles, landscape enhancement) within the neighborhood.
Proposed Actions:
• Develop streetscaping design for
Colonel Glenn to discourage
excessive speeding
• Examine traffic calming devices for
Western Hills Avenue, Ascension
Road, and Westwood Avenue
Speed humps along Western Hills Avenue have proven to be
effective. Residents would like to see more traffic calming
initiatives taken.
Update 2007 - 17 -
Residents are very proud of the beauty and calm residential feel of
the Westwood neighborhood.
Westwood
Zoning and Land Use
The types and condition of the businesses on Colonel Glenn seemed to strike up the
most complaints in the surveys. In addition, the participants in the plan development
process expressed concern with the worn down “trashy” look of Colonel Glenn and how
it affects the neighborhood. However through the process, the participants learned that
there is little that can be done to existing business owners along Colonel Glenn. Those
business owners either have proper zoning for what they are doing or were previously
granted nonconforming use status. Therefore, the Westwood residents have opted to
work towards preventing further degradation and working with existing business owners
on aesthetic improvements, such as sign controls, screening and adherence to code
ordinances.
Goal: Work toward establishing compatibility between land use and zoning in
the area, as well as compatibility of residential and non-residential uses.
Objective #1:
Protect the residential integrity of the neighborhood by maintaining adequate separation
or sufficient buffering between residential and non-residential uses.
Proposed Actions:
• Discourage and oppose additional
day care centers in the area that
will not be located on Colonel
Glenn
• Request that the City only allow
home occupations within the
neighborhood which do not
generate traffic, result in the
employment of additional persons
outside of the home, require any
alterations to the structure inside
or outside, or anything else
prohibited under the zoning code
(36-253(b)(6))
• Commercial and office activities should remain on Colonel Glenn
• Object to any applications requesting the conversion of single family homes--except
those on Colonel Glenn
• Request that planning staff reexamine allowable conditional and special use permits
in R-2 areas to restrict allowances that generate traffic and increase demand for
parking (i.e. daycare centers)
• Request Planning Department to strictly monitor variances and zoning within
boundary of Westwood Neighborhood Association.
Objective #2:
Update 2007 - 18 -
Support a Colonel Glenn Design Overlay District that encourages more stringent
requirements regarding commercial signage, lighting, parking, and landscaping to
improve its overall appearance.
Proposed Action:
• Organize a committee of residents and business owners to begin development of
design overlay criteria and standards
