(A) In all districts, any lighting used to illuminate an off-street parking area or sign shall be arranged so as to deflect light away from any adjoining residential zone or from the public streets. Direct glare from floodlights or similar sources, shall not be directed into any adjoining property or public streets, and all the source of all lights shall be hooded or controlled in some manner so as not to light adjacent property. Mitigative measures shall be employed to limit glare and spill light to protect neighboring parcels and to maintain traffic safety on public roads. These measures shall include lenses, shields, louvers, prismatic control devices and limitations on the height and type of fixtures. The city may also limit the hours of operation of outdoor lighting if it is deemed necessary to reduce impacts on the surrounding neighborhood.
(B) In residential areas, any light or combination of lights that cast light on any adjacent residential property shall not exceed 1/2 foot candle (meter reading) as measured at the property line. Lighting fixtures for new and renovated outdoor sports and recreational facilities that adjoin residential uses shall be designed to eliminate reflected glare and spill light from the bottom one-third of the reflector, and to shield the view of the arc tube from the residential property.
(C) In commercial and industrial areas, any light or combination of lights that cast light on any adjacent commercial or industrial property shall not exceed one foot candle as measured at the property line. All canopy lighting shall only be permitted under the canopy structure, and consist of canister spot lights or shoebox lights recessed into the canopy. No portion of the light source or fixture may extend below the bottom face of the canopy. Total canopy illumination below the canopy may not exceed 115 foot candles at ground level.
(D) The city may require submission of a light distribution plan if deemed necessary to ensure compliance with the intent of this section.
