[R.O. 2004 § 425.010; Ord. No.
01-11 § 1.1, 4-26-2001]
The purpose of this Chapter is to ensure that adequate lighting
is provided in commercial and industrial areas of the City and also
to ensure that such lighting does not spill over onto adjacent residential
areas. New lighting technologies have produced lights that are extremely
powerful, and these type lights may be installed in a manner creating
problems of excessive glare and light trespass. Excessive glare can
be unnecessary, annoying and cause safety problems. Light trespass
reduces everyone's privacy. This Chapter is intended to reduce
the problems of improperly designed and installed outdoor lighting.
It is intended to eliminate problems of glare and to prevent or curtail
light trespass.
