A. Purpose. The purpose of the "I-1" Light Industrial District is to provide sufficient space in appropriate locations for certain types of business and manufacturing, relatively free from offense, on modern landscaped buildings sites, and to make available more attractive locations for these businesses and industries. In order to preserve the land for industry and to avoid future conflicts between industry and residence, future residential uses are restricted.
B. Permitted Uses. A building or land in the "I-1" District shall be used only for the following purposes:
1. Any use permitted in the "C-1," "C-2" and "C-3" Districts, except dwellings other than permitted below.

4. Dwellings for resident watchmen and caretakers employed on the premises.
5. Establishments for the rent, sale and repair of heavy machinery.
6. Food lockers, freezers, cold storage facilities.

The open area shall be planted with trees and shrubs. A minimum of one (1) tree shall be planted per thirty (30) lineal feet or fraction thereof for any frontage along a residential zoning district. Required trees shall be at least two and one-half (2 1/2) inch caliper. Trees existing within any required greenbelt at the time of installation and which are larger than two and one-half (2 1/2) inch caliper shall be preserved and will count toward the minimum landscaping requirements. Newly planted species shall be hardy for the specified area. All landscaping shall be maintained in a healthy growing condition and be neat and orderly in appearance. The fifty-foot greenbelt shall not be used for off-street parking facilities or for loading spaces. Along the inner side (the industrial property side) of the greenbelt, except when the greenbelt adjoins a public street, there shall be provided either:
(1) A continuous visual screen with a minimum height of six (6) feet, such screen consisting of a compact evergreen hedge of foliage screening; or

11. Landscaping. The required front, side and rear yards shall be planted with trees and shrubs.
12. Maximum number of primary structures per lot: none.
E. Industrial Performance Standards.
1. Compliance With Standards. Any use or proposed use shall be operated so as to comply with the provisions of this Chapter. If it is deemed necessary by the Building Commissioner in order to determine compliance with these standards by any proposed or expansion of industry, the Commissioner may require any person, firm or corporation to retain an expert consultant or consultants to study and report as to compliance or non-compliance with these performance standards and to advise how a proposed use or proposed expansion of a use can be brought into compliance with these performance standards. Such consultants shall be fully qualified to give the required information and shall be persons or firms mutually agreeable to the Building Commissioner and to the persons or firms of the use in question. In the event of inability to select a mutual consultant, the Planning and Zoning Commission shall select the consultant. The cost of the consultant's services shall be borne by the owner, firm or corporation requesting such use. No use lawfully established before October 25, 1977, shall be hereafter altered or modified so as to conflict with or further conflict with these performance standards.
2. Outdoor Storage. All permitted and conditional uses shall be conducted within a completely enclosed building with no open storage of raw, in process, or finished material, and supplies or waste material, or finished or semi-finished products manufactured on the premises, unless screened from the street, or any residential or business district by fences or walls in accordance with these district regulations.
3. Noise. At no point on the boundary of a residential or business district shall the sound intensity level of any individual operation or plant (other than the operation of motor vehicles or other transportation facilities) exceed the decibel levels in the designated octave bands shown in the following table:
Maximum Permitted Sound Levels (decibels) |
|---|
Octave Band Frequency (cycles per second) | Along Residential District Boundaries | Along Business District Boundaries |
|---|
0 to 75 | 67 | 75 |
75 to 150 | 65 | 70 |
150 to 300 | 59 | 63 |
300 to 600 | 52 | 57 |
600 to 1,200 | 46 | 52 |
1,200 to 2,400 | 40 | 45 |
2,400 to 4,800 | 34 | 40 |
Above 4,800 | 32 | 38 |
Note: Measurement is to be made at the boundary of the nearest residential or business area or at any other point along the boundary where the level is higher. |
Sound levels shall be measured with a sound level meter and associated octave band filter manufactured according to standards prescribed by the American Standards Association. Measurements shall be made using the flat network of the sound level meter. Impulsive type noises shall be subject to the performance standards hereinafter prescribed, provided that such noises are capable of being accurately measured with such equipment. Noises capable of being so measured, for the purpose of this Chapter, shall be those noises which cause rapid fluctuations of the needle of the sound level meter with a variation of no more than plus or minus two (±2) decibels. Noises incapable of being so measured, such as those of an irregular and intermittent nature, should be controlled so as not to become a nuisance to adjacent uses. |
4. Smoke And Particulate Matter. The emission of smoke, dusts or any gaseous or particulate matter by any building in an amount sufficient to create a general nuisance to adjoining properties shall be prohibited. Total emission of smoke, dusts and any gaseous or particulate matter shall be limited to the following:
a. Ringelmann Requirements. All smoke and the emission of all other particulate matter in quantities sufficient to produce an opacity at any point greater than Ringelmann 3 shall be prohibited. The only exception shall be a plume consisting entirely of condensed steam. A Ringelmann 1 unit is defined as twenty percent (20%) density for one (1) minute. No more than fifteen (15) units of Ringelmann smoke shall be permitted per hour and no smoke more intense than Ringelmann 2, except that during one (1) hour of a twenty-four (24) hour day, thirty (30) units of smoke may be emitted, but with no smoke more intense than Ringelmann 3 as shown on the Ringelmann Chart.
b. The emission, from all sources within any lot area, of particulate matter containing more than ten percent (10%) by weight, of particles having a particulate diameter larger than forty-four (44) microns, shall be prohibited.
c. Dust and other types of air pollution, borne by the wind from such sources as storage areas, yards, roads and the like within lot boundaries, shall be kept to a minimum by appropriate landscaping, paving, oiling, fencing or acceptable means. Emission of particulate matter from such sources in excess of the weight limitation herein specified shall be prohibited.
5. Odors. No odor shall be emitted by any use permitted in this district in such quantities as to be readily detectable by an average observer at any point on the boundary line of the premises or beyond.
6. Noxious Gases. Processes and operations of permitted uses capable of dispersing gases or toxic particulates into the atmosphere must be hooded or otherwise suitably enclosed. The emission of such toxic gases or particulate matter shall be from a stack.
7. Glare And Heat. Operation producing intense light and heat shall be performed within an enclosed building and not be visible beyond any lot line bounding the property whereon the use is conducted.
8. Vibration. Any operation or activity which shall cause at any time and at any point beyond the boundaries of the lot, earth-borne vibrations, other than background vibrations produced by some source not under control of this Chapter, such as the operations of motor vehicles or other transportation facilities, in excess of the limits set forth in Column I of the table below shall be prohibited. In addition, any operation or activity which shall cause at any time and at any point in a residence district earth-borne vibrations in excess of the limits set forth in Column II of the table below shall be prohibited. Vibration shall be expressed as displacement in inches and shall be measured with a three (3) component measuring system approved by the Building Commissioner.
Frequency (cycles per second) | I Displacement (inches) | II Displacement (inches) |
|---|
0 to 10 | 0.0008 | 0.0004 |
10 to 20 | 0.0005 | 0.0002 |
20 to 30 | 0.0002 | 0.0001 |
30 to 40 | 0.0002 | 0.0001 |
40 to over | 0.0001 | 0.0001 |
Note: Impact vibrations which are discrete pulses that do not exceed one hundred (100) impulses per minute shall be permitted twice the displacements shown above in Columns I and II. |
