(A) Purpose. The purpose of this section is to establish standards for the management of illicit discharges, soil erosion, sediment deposition, and the environmental impacts of land uses (e.g., noise, vibration, air quality, water quality, and glare), in order to ensure that the city continues to provide a desirable environment for residences, recreation, education, culture, commerce, and industry.
(B) Compliance. Compliance with the requirements of this section shall not be interpreted as authorizing a practice or operation which would constitute a violation of any other applicable statute, ordinance, rule, or regulation. Where these regulations conflict with other regulations, the more stringent regulation shall apply.
(C) Administration. All uses of land or structures shall conform to the standards in this section.
(D) Noise. No use, operation, or activity shall cause or create noise in excess of the sound levels prescribed in Chapter 134, Noise Control, of the city’s Code of Ordinance.
(E) Vibration.
(1) Generally. No land use shall produce vibration that exceeds the limits set out by this section.
(2) Exceptions. This section does not apply to vibration generated by:
(a) Noises emanating from construction activities between the hours of 7:00 a.m. and 7:00 p.m. that are temporary in nature.
(b) Transient noises from moving vehicles, such as trucks and automobiles or trains.
(3) Standards. The standards of Table 156.C.011-2, Vibration Standards, shall be met, except as provided in division (E)(2), above.

Table Notes: 1 Vibrations that do not exceed 60 per minute may be twice this value. 2 Vibrations occurring no more than eight times in a 24-hour period with a maximum separation of one minute. | ||||
(4) Measurement. An operator trained to measure vibrations shall make all such measurements and shall submit and certify them with the city.
(H) Air quality.
(1) Generally. Air quality shall be maintained according to state and federal standards. Demonstration of compliance shall be provided as required by this section.
(2) Emissions. Applicants for the approval of uses that will emit air pollutants that are subject to regulation pursuant to the federal Clean Air Act shall demonstrate compliance with that law.
(3) Control of wind-blown dust. Landowners shall control wind-blown dust.
(I) Glare.
(1) Glare from use. Glare from any process (such as or similar to arc welding or acetylene torch cutting), which emits harmful ultraviolet rays shall be performed in such manner as not to be seen from any point beyond the property line, and as not to create a public nuisance or hazard along lot lines or street rights-of-way.
(2) Glare from buildings and structures. Buildings and structures (including signs) shall be designed and oriented to avoid glare that materially interferes with the safe operation of streets.
(J) Erosion control.
(1) Storm water management. Measures to protect water quality and to manage the quantity and velocity of stormwater runoff shall be implemented pursuant to the standards set out in Chapter 55, Erosion and Sediment Control for Construction Sites in the city's Code of Ordinances.
(2) Grading, erosion, and sediment control. Measures to protect water quality during construction and for land disturbance activities shall be implemented pursuant to the standards set out in Chapter 55, Erosion and Sediment Control for Construction Sites in the city's Code of Ordinances.
(K) Other performance standards. In addition to the performance standards of this section, the following shall apply to all uses:
(1) Outdoor storage.
(a) Outside storage of non-saleable merchandise or other materials shall not be visible from the public right-of-way.
(2) Snow storage. Adequate area shall be provided on the lot for snow storage or provisions shall be made by the property owner for the snow to be hauled off-site.
(3) Use compatibility.
(a) All uses shall be designed and operated to be compatible with the adjacent residential uses.
(b) Limitations on design and operation of uses shall include architectural and building mass, hours of operation, delivery hours, noise and lighting controls, signage, and traffic considerations.
(4) Utilities. All utilities shall be placed underground, where feasible.
