VI. LIGHTING BY SPECIAL PERMIT ONLY - User’s Guide
This section addresses types of lighting that are intrusive or complex in
their impacts and need a higher level of scrutiny and/or site sensitivity.
It should be noted that safety could be compromised if lighting
conforming to this ordinance is located adjacent to excessively
bright and/or glaring lighting.
It is important that the authority set clear and reasonable guidelines
for applying for a special lighting use permit, and establish rules and
procedures for granting or refusing them. They may differ from
existing special use policies, in which case one or the other may be
changed to achieve the overall goal of effective lighting without glare,
sky glow, or light trespass.
SPORTS FIELD LIGHTING
For athletic and sports fields, the appropriate level of lighting will depend
on the Class of Play and Facilities. Class of Play is divided into 4 categories,
depending on the number of fixed spectator seats. (Competition play
intended for nighttime TV broadcast may require higher lighting levels).

initial luminaire lumens or the total lighting load exceeds 160,000
lumens.
