Item 7A City of Southlake, Texas
MEMORANDUM
May 3, 2002
TO: Billy Campbell, City Manager
FROM: Ricky Black, Director of Public Safety(Ext. 2421)
SUBJECT: Request for a variance to Lighting Ordinance No. 693-B for Thomas Soccer
Fields located at 845 S. Kimball Avenue.
Action Requested: City Council consideration of lighting ordinance variance for Thomas
Soccer Fields.
Background
Information: Mr.Dalen Thomas has a pending request for zoning and concept plan
approval(Case No. ZA 020-02) for the subject property. In order to
develop it as he desires, he is also requesting a variance to the Lighting
Ordinance.
The request is specifically to vary three standards in the ordinance. First,
section 4(b.)to allow Metal Halide (white) light fixtures instead of the
high pressure sodium type specified. Second,to vary section 5 (b.) to
exceed the maximum light permitted on site from 20 footcandles to an
average of 51.88 on the playing fields with a maximum spot level to be
74.5 footcandles. Third to vary section 5 (a.)the lighting limit at the
property line from the 5 footcandles permitted to 36.8 footcandles on the
east and south property lines and 13 footcandles on the west property line
(Kimball Ave. R. O.W.). There is no request for variance to the north.
It should be noted there is not a request for variance to the glare issue as
required by sections 4(d.) and 8 (c.) of the ordinance. The applicant has,
at the request of Building Services, specifically committed that no fixtures
will produce a hazardous glare to traffic on Kimball Avenue as determined
by the Chief Building Official. Also, at the previous City Council meeting
on April 16,2002, the applicant withdrew his request to illuminate the
north field adjacent to residential property.
Financial
Considerations: Not Applicable

fixtures shall be high pressured sodium lights or other lights giving a similar soft
lighting effect. The building official may approve alternate lighting if he finds
that it:
(1) provides at least approximate equivalence to the applicable specific
requirements of this Ordinance; and
(2) is otherwise satisfactory and complies with the intent of this Ordinance.
(d) Luminaires causing glare at property line or in vehicle areas on streets or parking
lots are prohibited.
SECTION 5.
ILLUMINATION
(a) The intensity of illumination pr classification of the neighboring property and
shall not exceed the following intensities, as measured from the property line of
the neighboring property:
Footcandles Footcandles
Si Zoning of Neighboring Property Horizontal Vertical
Agricultural, Single-family, and two-family residential districts 0.2 0.5
Multiple-family residential districts 0.5 0.5
Nonresidential districts, streets 3.0 3.0
Light industrial districts 5.0 5.0
(b) The maximum outdoor computed or measured illumination level on a property
shall not exceed 20 foot candles outdoors at any point, except that lighting
under canopies (such as service stations) shall not exceed 30 foot candles.
SECTION 8.
ENFORCEMENT.
(c) Shielding. Luminaires shall be aimed in such a manner that the viewer's eye,
five feet above ground at or beyond the property line, shall not be exposed to
fixture luminance within the floodlight beam of the luminaire. If such
luminaires cannot be aimed they shall be shielded such that the light source is
effectively concealed from view from the neighboring property. Shielding may
be accomplished by louvers, baffles, visors, or shields placed on the luminaires,

Dear sirs:
This letter addresses lighting issues pertaining to our proposed soccer project
Our proposed project is for four outdoor fields. Three of these fields are adjacent to each
other and run along the Southern border of our property. A fourth field is a stand alone
field at the North end of our property. At the City Council Meeting on April 16th we
agreed to withdraw our request to light the fourth field to the North. Thus,the following
applies to the three fields to the South.
Lighting Descriotiog
The following description and the attached photometrics are based on a proposal
submitted to us by Musco Sports Lighting.
The Musco proposal is as follows:
thy Three poles on each side of each field.
The six poles around the center field would light the fields on either side in a back-to-back
configuration.
The poles are 60'in height.
The position of the poles is as displayed on the attached concept plan.
The average on field illumination is estimated to be 51.88 footcandles
The range of on field illumination is estimated to be 37.3-74.5 footcandles
The average spill illumination at the property lines to the East and the South is estimated
to be 20.5 footcandles
The range of spill illumination at the property lines to the East and the South is estimated
to be 1.1-36.8 footcandles
The average spill illumination at a distance of 50'from any of the three fields is estimated
to be 4.9 footcandles
The range of spill illumination at a distance of 50'from any of the three fields is estimated
to be 0.8-6.7 footcandles
(Note: Our neighbors to the East and the South, Southlake Schools and Mr.Ralph Segars
respectively, have each provided us with a letter stating that they are agreeable to these
levels of spill illumination.)
The average spill illumination on Kimble road to the West is estimated to be 4.5
footcandles
The range of spill illumination on Kimble Road to the West is estimated to be 0.3-13.0
footcandles
Details of these measurements are provided in the attached photometrics.

Spill illumination in excess of 3-5 footcandles on to neighboring property
(This variance was approved at the first City Council reading on 4/16/02)
In addition,at the request of the Building Services Department,we agree to commit to the
