(A) Purpose. The purpose of performance standards is to establish specific and quantifiable limitations on identified types of pollution and other activities which have a high nuisance potential. The performance standards apply in all zoning districts unless specifically stated to the contrary.
(B) Performance Standards Regulating Exterior Lighting.
(1) Exterior lighting shall be designed and arranged to limit direct illumination and glare upon or into any contiguous parcel. Reflected glare or spill light shall not exceed five-tenths foot-candles as measured on the property line when abutting any residential parcel and one foot-candle on any abutting commercial or industrial parcel. Street lights installed in public right-of-way shall be excepted from these standards.
(2) 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.
(3) No flickering or flashing lights shall be permitted.
(4) Direct, off-site views of the light source shall not be permitted except for globe and/or ornamental light fixtures approved in conjunction with a site and building plan. Globe and ornamental fixtures shall only be approved when the developer can demonstrate that off-site impacts stemming from direct views of the bulb are mitigated by the fixture design and/or location.
(5) The city may require submission of a light distribution plan if deemed necessary to ensure compliance with the intent of this chapter.
(C) Performance standards regulating noise and vibration.
(1) Noises emanating from any use shall be in compliance with and regulated by the standards of the Minnesota Pollution Control Agency. Any use established or remodeled after the effective date of this chapter shall be so operated as to prevent vibration discernable at any point beyond the lot line of the site on which such use is located. The city may also limit the hours of operation of outdoor noise if it is deemed necessary to reduce impacts on the surrounding neighborhood.
(2) Ground vibration and noise caused by motor vehicles, trains, aircraft operations or temporary construction or demolition shall be exempt from these regulations. However, if deemed appropriate, the city may establish limits on the hours of operation of temporary construction or demolition operation to limit off-site impacts.
(D) Performance standards regulating smoke and particulate matter. No use shall produce or emit smoke, dust or particulate matter exceeding applicable regulations established by the Minnesota Pollution Control Agency.
(E) Performance standards regulating odor. No use shall produce unreasonable or disturbing odors beyond the property line exceeding applicable regulations established by the Minnesota Pollution Control Agency.
(F) Performance standards regulating toxic or noxious matter. No use or operation shall emit a concentration of toxic or noxious matter across the property line which exceeds applicable regulations of the Minnesota Pollution Control Agency.
(G) Performance Standards Regulating Radiation. No operation shall be conducted which exceeds the standards established by applicable regulations of the Minnesota Department of Health.
(H) Performance standards regulating heat and humidity. No use shall produce any unreasonable, disturbing or unnecessary emissions of heat or humidity beyond the property line which cause material distress, discomfort or injury to persons of ordinary sensitivity.
(I) Performance standards regulating electromagnetic interference. No use shall produce electromagnetic interference with normal radio or television reception in any residential district, or exceed applicable standards established by any applicable federal or state regulations.
(J) Performance standards regulating liquid or solid waste. All uses shall be subject to applicable regulations of the city governing discharge into a public storm or sanitary sewer, waterway or stream.
