The preliminary plat, as approved, together with covenants, deed restrictions, controls or special conditional use permits as may be attached to it, shall become a part of the ordinance establishing the zoning change. Any substantial change to the plan will require resubmission to and approval by the Planning Commission and the Council.

The site plan shall show the location and extent of proposed buildings, parking, loading, access drives, landscaping, sewage and water systems and any other improvements. Plans will be examined for compliance with the recorded preliminary plat and attachments thereto, and the Planning Commission shall consider the plans and make its recommendations to the Council, which shall have the power to approve or disapprove the same.
(H) Performance standards.
(1) Intent. It is the intent of this division (H) to provide that industry and related activities shall be established and maintained with proper appearance from streets and adjoining properties and to provide that each permitted use shall be a good neighbor to adjoining properties by the control of the following.
(2) Standards.
(a) Landscaping. All required yards shall either be open landscaped and green areas or be left in a natural state. If any yards are to be landscaped, they shall be landscaped attractively with lawn, trees, shrubs and the like. Any areas left in a natural state shall be properly maintained in a sightly and well-kept condition. Yards adjoining any of the classes of residence districts shall be landscaped with buffer planting screens. Plans of the screens shall be submitted for approval as a part of the site plan and installed prior to issuance of a certificate of occupancy for any tract in the district.
(b) Noise.
1. Noise shall be measured on any property line of the tract on which the operation is located. Noise shall be muffled so as not to become objectionable due to intermittence, beat frequency, shrillness or intensity. At the property line, the sound pressure level of noise radiated continuously from a facility shall not exceed the values given in the following table. The sound pressure level shall be measured with a sound level meter and an associated octave band analyzer, both of which are manufactured to specifications published by the American Standard Specifications for an Octave-Band Filter Set for the Analysis of Noise and Other Sounds, Z24, 10 1953, American Standards Association, Inc., New York, NY. Measurements shall be made using the flat network of the sound level meter.
2. Maximum permissible sound pressure levels at specified points of measurement for noise radiated continuously from facility.
Band Cycles Per Second/ Frequency Band Cycles Per Second | Maximum Permitted Sound Levels (Decibels) |
Band Cycles Per Second/ Frequency Band Cycles Per Second | Maximum Permitted Sound Levels (Decibels) |
20 - 75 | 72 |
75 - 150 | 67 |
150 - 300 | 59 |
300 - 600 | 52 |
600 - 1,200 | 46 |
1,200 - 2,400 | 40 |
2,400 - 4,800 | 34 |
Over 4,800 | 32 |
(c) Odors. No activity or operation shall cause at any time the discharge of odorous matter in concentrations as to be readily detectable at any point along the property boundary line or in a concentration as to create a public nuisance or hazard beyond the boundary line.
(d) Glare. Glare, whether direct or reflected, such as from floodlights, spotlights or high temperature processes, and as differentiated from general illumination, shall not be visible at any property line.
(e) Exterior lighting. Any lights used for exterior illumination shall direct light away from adjoining properties.
(f) Vibration. Vibration shall not be discernible at any property line to the human sense of feeling for three minutes or more duration in any one hour. Vibrations of any kind shall not produce at any time an acceleration of more than one-tenth gravities or shall result in any combination of amplitudes and frequencies beyond the “safe” range of Table VII, United States Bureau of Mines Bulletin No. 442, Seismic Effects of Quarry Blasting, on any structure. The methods and equations of the Bulletin No. 442 shall be used to compute all values for the enforcement of this provision.
(g) Smoke. Measurements shall be of the point of emission. The Ringlemann Smoke Chart published by the United States Bureau of Mines shall be used for the measurement of smoke. Smoke not darker or more opaque than No. 4 on the chart may be emitted, except that smoke not darker or more opaque than No. 2 on the chart may be emitted for periods not longer than four minutes in any 30 minutes. These provisions, applicable to visible grey smoke, shall also apply to visible smoke of a different color with an equivalent apparent opacity.
(h) Dust. Solid or liquid particles shall not be emitted at any point in concentrations exceeding three-tenths grains per cubic foot of the conveying gas or air. For measurement of the amount of particles in gases resulting from combustion, standard corrections shall be applied to a stack temperature of 500°F and 50% excess air.
(i) Fumes or gases. Fumes or gases shall not be emitted at any point in concentrations or amounts that are noxious, toxic or corrosive. The values given in Table I (Industrial Hygiene Standards - Maximum Allowable Concentration For Eight-Hour Day, Five Days Per Week), Table III (Odor Thresholds), Table IV (Concentrations of Substances Causing Pain in the Eyes) and Table V (Exposure to Substances Causing Damage to Vegetation) in the latest revision of Chapter 5, “Physiological Effects,” that contains tables, in the Air Pollution Abatement Manual, by the Manufacturing Chemists’ Association, Inc., Washington, D.C., are hereby established as guides for the determination of permissible concentration or amounts. Detailed plans for the elimination of fumes or gases may be required before the issuance of a building permit.
(j) Hazard. Every operation shall be carried on with reasonable precaution against fire and explosion hazards.
(k) Water supply. The design and construction of water supply facilities and water supply source shall be in accord with city health standards and requirements.
(l) Waste. All sewage and industrial waste shall be treated and disposed of in a manner as to comply with the city health standards and requirements.
(3) Investigations and tests. In order to ensure compliance with the performance standards set forth above, the Council may require the owner or operator of any permitted use to have made the investigations and/or tests as may be required to show adherence to the performance standards. The investigation and/or tests as are required to be made shall be carried out by an independent testing organization approved by the city. The costs incurred in the investigation or testing shall be ordered by the owner or operator and shared equally by the owner or operator and the city unless the investigation and tests disclose non-compliance with the performance standards; in which situation the entire investigation or testing cost shall be paid by the owner or operator.
