ITEM NO.: 5 FILE NO_: Z-88
NAME: Entergy Lawson Road Substation — Conditional
Use Permit
LOCATION: 14134 Lawson Road
OWNER/APPLICANT: Emprise, LLC/Entergy Arkansas
PROPOSAL: A conditional use permit is requested to allow a
utility substation to be constructed on this R-2 zoned,
18.07 acre tract.
1. SITE LOCATION:
The site is located outside of the city limits, within the City's zoning
jurisdiction. The property is approximately % mile south of Lawson Road,
one mile west of the city limits.
2. COMPATIBILITY WITH NEIGHBORHOOD:
The site is a wooded hilltop located in a rural, mostly undeveloped area.
Large areas of undeveloped property extend to the south, west and east.
A few single family homes on larger tracts are located to north and east,
off of Lawson Road. The 18 acre tract is part of a 200+ acre property
that has previously been approved for a residential subdivision (Ventana
Ridge). The new subdivision will eventually be developed adjacent to
the substation. The substation is to occupy the center of the wooded,
18+ acre tract with a wooded buffer to remain around the compound and
cleared portion of the site. As much as is possible, the proposed
substation appears to be compatible with the neighborhood.
Notice of the commission's public hearing was sent to all owners of
properties located within 200 feet of the site and SWLR United for
Progress -
-Notice had previously been send to property owners within a
X mile of the site for a hearing in, December 2012 before the Arkansas
Public Service Commission.._,.,
3. ON SITE DRIVES AND PARKING:
In conjunction with the proposed new residential subdivision, a road bed
has been created, running off of Lawson Road. Entergy has an access
easement corresponding to the road bed. A gravel driveway will be
constructed off of the road bed to the substation. A gated entry will be

placed on the driveway to match the architecture of the subdivision.
Additional gates will be placed where the driveway enters the actual
fenced compound. At the time the road is paved, a portion of the Entergy
driveway will be paved to eliminate the tracking of gravel onto the paved
road. There is not a parking lot as such for the substation but there is
gravel parking area and driveway sufficient to serve any staff or
technicians on the site when needed.
4. SCREENING AND BUFFERS:
Site plan must comply with the City's landscape and buffer ordinance
requirements.
The City Beautiful Commission recommends preserving as many existing
trees as feasible on this site. Credit toward fulfilling Landscape Ordinance
requirements can be given when preserving trees of six (6) inch caliper or
larger.

SUBDIVISION COMMITTEE COMMENT: (APRIL 24, 2013)
The applicants were present. Staff presented the item and noted little additional
information was needed. Staff requested some information on the anticipated
height of the structures and a signage plan, if signage was proposed. Staff
stated all areas indicated as wooded buffers were to be marked and protected
with orange contractor's fencing prior to any site work commencing and the
location -if the fencing was to be verified by staff. Staff stated the driveway apron
and a portion of the driveway were to be paved at the time the new street was
paved to prevent gravel from being pulled into the street.
Comments from the other reviewing agencies were presented.
The applicants were advised to provide responses to staff issues by Wednesday,
May 1, 2013. The Committee forwarded the item to the full Commission after
determining there were no other issues.
STAFF ANALYSIS:
Entergy Arkansas is requesting approval of a conditional use permit to allow
for construction of a utility substation on this unimproved, R-2 zoned, 18.07 acre
tract. The 18.07 acre tract is located within a 200+ acre property that has

A road bed has been created off of Lawson Road, through the 200 acres. The
18..07.acre tract.fronts. on the -new road. _A_driveway-w-iil_extertsl_.of-oflhe-o.�ad_
approximately 400 feet to the actual substation site. The property is not within
the city limits but is in the City's zoning jurisdiction.
For several years, Entergy has been working to locate a substation in this
general area. The continual increase of planned commercial and residential
development in the surrounding area, along with the current substation for this
area being at capacity, has made it necessary for EAI to construct a new
distribution substation facility to adequately serve the area in the future.

The property is located east of an existing Entergy 115kV transmission line. A
new transmission line will extend from the substation, across the new road, to the
115kV line. The 18.07 acre tract is located approximately 1,400 feet south of
Lawson Road. Although the tract is located within the 200+ acres previously
approved for Ventana Ridge, it will not be part of the subdivision and will have no
bill of assurance. An access easement and utility easement are located over the
new road to provide access from Lawson Road to the site. No on -site water or
wastewater systems are existing or proposed. Entergy has agreed to fund the
installation of an additional fire hydrant on Lawson Road at the request of the
Crystal VFD. A 250' X 350' area located in the middle of the 18.07 acre site will
be fenced with a six foot tall chain link fence with barbed wire, enclosing the
electrical operating facilities.
The site is currently in mature forest cover. In general, this forest cover will
remain as buffer and landscaping screening outside the proposed limits of
clearing within the site. An area around the fenced compound will be cleared as
will a pathway for the connecting transmission lines. The applicant estimates
approximately half of the site to be cleared with the remainder to be preserved in
its current mature wooded state.
The noise level from the equipment in the substation will be approximately 50dB.
Household items noise level range from 43dB for a refrigerator to 60dB in a
normal adult conversation. Low-level'.operational lighting with additional
emergency lighting will be placed within the fenced compound. Signage on the
site will be as is typical for an Entergy Substation; informational, caution,
instructional.
Entergy will install a proper apron and 50 feet of paved driveway at the time the
new road is constructed and paved. The remainder of Entergy's driveway into
and within the substation will remain gravel.
Staff is supportive of the proposal.

the following conditions:
1. Compliance with the comments and conditions outlined in Sections 4, 5 and
