MODEL LIGHTING ORDINANCE - TEXT
III. GENERAL REQUIREMENTS (cont.) - Ordinance Text
Exceptions to III.(C.) 1. Automatic lighting controls are not
required for the following:
a. Lighting under canopies.
b. Lighting for tunnels, parking garages, garage entrances,
and similar conditions.
CURFEW REQUIREMENTS - User’s Guide
The intent is to reduce or eliminate lighting after a given time. Benefits
include reduced environmental impact, longer hours of improved
astronomy, energy savings, and improved sleeping conditions for
residents. Additionally, some police departments have indicated that
post-curfew light reductions make drive-by patrolling easier because it
allows them to see further into and through a site.
The authority should determine the time of curfew and the amount of
lighting reduction based on the character, norms and values of the
community.
Typically, curfews go into effect one hour after the close of business.
Restaurants, bars and major entertainment facilities such as sports
stadiums, may require the curfew go into effect two hours after the
close of business. The authority may elect to have no curfew for facilities
with shift workers and 24 hour operations, or to extend the curfew time
to meet specific needs. The MLO can be modified to address those
concerns.
Areas without street lights or with very low ambient light levels should
consider turning off all non-emergency lighting at curfew while
commercial areas or urban areas may prefer a reduction in lighting
levels. A reduction of at least 30% is recommended for most uses.
