COMPREHENSIVE PLAN: The Coppel! Comprehensive Plan shows the property as suitable
for office, showroom and warehouse use.
DISCUSSION:
This is a case where an existing tenant needs to make improvements to
increase business. Basically, Superior Air Parts produces aircraft engines.
The engines require a test run before they can be accepted and shipped to
the ultimate user. To accommodate the user, the necessary test runs
generate considerable noise which, in the past, have been performed
totally inside a building. The engines will still remain within the building,
but cooling towers, fans for cooling the engines, and fuel tanks (the test
cells) need to be added to the back of the existing warehouse to service the
test runs. This additional equipment will generate noise. The applicant
proposes to build a 14' 3" -high wall to screen this added equipment. The
wall is proposed to be 42-feet long and initially 25' 9" deep. The most
recent revised plans show a wall 17' deep. We feel the longer wall is
more appropriate here as noise generated from the activity would be better
controlled. In addition, the original proposal indicated a space of 12'
between the end of the screening wall and the face of the building. The
most recent submittal shows openings of 20'. Again, we feel a longer wall
would more effectively control the noise being generated. At any rate,
noise is a concern, and it is our understanding that the applicant will
address the noise issue at the public meeting. We have included a
condition regarding the noise issue in our staff recommendation. The wall
will match the existing warehouse building and cannot be seen from the
public right-of-way. Nothing else on site will be changed including
parking, lighting, landscaping, color, etc. What will be added are two fuel
tanks--one with a capacity of 500 gallons and one of 1000 gallons, three
cooling towers and two air blowers.
As stated above, of primary concern to staff is the additional noise that would be emitted from
the proposed equipment. The applicant has assured us that any noise generated will be within
the City's noise guidelines and has stated in his letter of February 14 that a sound insulation
contractor will supply us with details on handling sound emission. We did not receive that
information prior to the docket going out, but the applicant has advised us that appropriate
information will be submitted at the Planning Commission meeting.

Letter of Transmittal
14 February 2007
Mr. Gary L. Sieb
Director, Planning and Zoning Commission
City of Coppell
255 Parkway Blvd.
Coppell, TX 75019
Dear Mr. Sieb,
Please find enclosed our Site Plan Application documents and our $400 check for
the filing fee for the installation of two aircraft piston engine Test Cells at Superior
Air Parts, Inc. located at 621 S. Royal Lane, Suite 100.
Superior Air Parts produces certified aircraft piston engines and component parts
for aircraft piston engines. The engines require a test run before acceptance and
shipping. The test cells that we propose for our site are to be used for these
acceptance test runs. These test cells contain a dynamometer and instrumentation
to measure the performance of the engines. The dynamometer requires cooling
water and a cooling tower to remove the cooling water heat. These cooling towers,
fans for cooling the air cooled aircraft engines, and fuel tanks are proposed to be
placed outside our building according to the site plan that we are submitting. This
equipment will be surrounded by a masonry wall (exact construction details are to
be determined) that matches the appearance of our building. The existing outside
building lighting will not need to be changed. The engine test cells themselves will
be sound insulated and our contractor will be supplying the details on sound
emissions at a later date. The test cells will be equipped with fire suppression
equipment and ventilation fans that will run anytime that the valves from the fuel
tanks to the test cells are open.

Re: Proposed construction of a 3-sided enclosure and installation of cooling towers and
fuel tanks
Dear Mr. Whitley,
We have reviewed the drawings that you have submitted to the City for approval and we
approve conceptually with the outside structure and the equipment contained within it.
Any structure and equipment will need to meet applicable building codes including any
pertinent City ordinances. All parties agree that the wall finish will have to match the
existing building.
Please contact me at your earliest convenience so that we can discuss further the plans for
moving forward with this project and the details that need to be agreed to before
construction starts.
Sincerely,
Duke Realty Corporation

Superior Air Parts Response
to City of Coppell ORC Report of
February 23 2007
o How are CO levels monitored and removed from
area?
DThe engine test cells are equipped with a commercial CO
monitor approximately four feet from the floor. The monitor
sounds an alarm when preset levels of CO are exceeded
DThe cells are equipped with a ventilation system with an
interlock that prevents engine operation (the only time that
CO is produced) without test cell ventilation fans operating
All requirements of the City of Coppel! will be
com lied with.
Superior Air Parts Response
to City of Cappell ORC Report of
February 23 2007
D LI zoning only allows for a nominal amount of odor,
noise, etc. Do these operations exceed "nominal".
DThe test cells are a commercial test cell enclosure that is
sound insulated and provided with a sound insulated
ventilation system. Noise levels from the test cell are low.
The ventilation fans will produce some noise but these
levels are also low. The previous agreement with neighbors
were when operating a propeller test stand without
complete engine enclosure. The planned test cells are far
below the level of this previous test arrangement. Exhaust
from the engines is essentially odorless, the odor is
approximately the same level and character as that of the
exhaust from the cars in the parking lot.
All requirements of the City of Coppel! will be
com lied with.
Superior Air Parts Response
to City of Coppell ORC Report of
February 23 2007
D Fuel tanks and associated piping shall be installed in
accordance with current ordnances adopted by the
City of Coppell. Proper "placarding" will be required
to be visible from the fire lane.
DSuperior confirms and has added to our drawings that all
ordnances (including those relating to fuel tanks, piping and
placarding) will be complied with.
All requirements of the City of Coppel! will be
com lied with.
