EXECUTIVE
SUMMARY: Carroll I.S.D. is requesting a variance to Lighting Ordinance No. 693, as amended,
related to the replacement of the existing tennis court lights located at Carroll Senior
High School located at 1501 W. Southlake Blvd. Southlake, Texas.
REQUEST: Carroll I.S.D. is requesting a variance to Lighting Ordinance No. 693, as amended,
related to the replacement of the existing tennis court lights located at Carroll Senior
High School. The existing lights were installed prior to the City’s Outdoor Lighting
Ordinance being in place. CISD proposes changing the current metal halide system
to a more efficient LED system. Any changes to an existing system require that the
new system comply with the current Lighting Ordinance. The proposed lighting does
not comply with the permitted lighting type, maximum intensity of illumination
permitted by the lighting ordinance. The variances requested are as follows:

Department of Planning & Development Services
The City Council, after receiving a recommendation from the Planning and Zoning
Commission, may grant a modification or variance from the provisions of the
Lighting Ordinance in any of the following circumstances:
1) Upon finding that strict application of the Ordinance would not forward
the purposes of this Ordinance or that alternatives proposed by the
applicant would satisfy the purposes of this Ordinance at least to an
equivalent degree.
2) Upon finding that an outdoor light or system of outdoor lights required for a
particular use cannot reasonably comply with the standard and provide
sufficient illumination for safety or security as determined by recommended
practices adopted by the Illuminating Engineering Society of North
American for the particular use or other evidence submitted by a
professional engineer or other professional organization.
3) Upon finding where a literal application or enforcement of the regulations
would result in practical difficulty or unnecessary hardship and the relief
granted would not be contrary to the public interest or the intent but do
substantial justice and be in accordance with the spirit of the regulations
and this Ordinance.
ACTION NEEDED: Consider variance request.
