(a)   Intent. It is the intent of the City, in the creation of the I-3 Industrial Park District and its appurtenant regulations, to encourage in appropriate locations the development of "industrial subdivisions" which will be characterized by a parklike openness and attractive modern buildings set in a landscaped environment. Industries located therein shall be harmoniously integrated with each other and compatible to that portion of the community within which the industrial park is located. Area requirements for the I-3 District are designed to promote the concentration of these desirable industries so that necessary common facilities may be provided and used and in order that problems of utilities, access, traffic control and other services may be more easily solved.
   (b)   Permitted Uses.
(1)   A building or premises may be used for the following purposes in an I-3 District:
         A.   Public utilities, whether owned and operated municipally or privately.
         B.   Research laboratories.
         C.   Heliports.
         D.   The assembly, manufacturing, compounding, processing, packaging, treatment or fabrication of bakery goods, candy, ceramics, cosmetics, clothing, electrical and electronic equipment, jewelry, instruments, optical goods, pharmaceuticals, toiletries and food products, except fish and meat products, sauerkraut, vinegar, yeast and rendering or refining of fats and oils.
         E.   The manufacturing, compounding, assembling or treatment of articles of merchandise from the following prepared materials: bone, cellophane, canvas, cloth, cork, feathers, felt, fibre, fur, glass, hair, horn, leather, paper, plastics, precious or semiprecious metals or stones, shell, textiles, tobacco, wood (except planing mill), yarns and those substances or compounds which are not combustible, inflammable, explosive or likely to create fire, radiation or explosive hazards to surrounding property. Except the foregoing, other articles, substances or compounds may be stored and used in reasonable quantities, provided such storage and use are permitted by the Board of Zoning Appeals after recommendation therefor by the Planning Commission and subject to such conditions as the Board of Zoning Appeals may deem necessary in the interests of public safety.
         F.   Customary accessory uses to any of the foregoing, not in conflict with any other provisions of this Zoning Code.
         G.   Other uses of a like nature as approved by the Planning Commission in accordance with the City Charter.
            (Ord. 66-103. Passed 12-19-66.)
         H.   Sexually oriented business, as defined in Chapter 1273, provided it complies with the requirements of said chapter.
            (Ord. 98-34. Passed 6-15-98.)
(2)   The following special uses shall be permitted in an Industrial Park District, provided that buildings and accessory buildings and uses comply with all requirements of this District and that all such uses not involving buildings or accessory buildings have the approval of the Planning Commission:
         A.   Cafeterias or restaurants specifically designed and primarily intended for use by officers and employees of uses permitted in the Industrial Park District, but not necessarily exclusively for their use.
         B.   Bowling alleys, auditoriums, meeting rooms or other buildings primarily intended for the mutual use of the permitted uses located within the District, for meetings, programs, displays, recreation and other such uses as the industrial users of the District may deem necessary. These facilities shall be prohibited for use by organizations, clubs and fraternities not specifically a part of the industrial users of the District.
         C.   Outdoor recreational facilities designed and intended for use by officers and employees of those industries within the District. These facilities and associated uses shall comply with all requirements of this chapter with respect to front, side and rear yard clearances. These facilities, if lighted, must be shielded away from any thoroughfares and residential districts.
            (Ord. 66-103. Passed 12-19-66.)
         D.   Wireless telecommunications towers and related wireless telecommunications facilities.
            (Ord. 99-46. Passed 10-24-99.)
   (c)   Prohibited Uses. Uses or processes which would affect an extensive area or be contrary to the public health and welfare in the City are prohibited in this and all other zoning districts. Prohibited uses include, but are not limited to, bituminous concrete manufacturing facilities, commonly known as "asphalt plants".
(Ord. 98-87. Passed 3-1-99.)
   (d)   Building Height. The maximum height of any building at each of the building lines shall be thirty-five feet. For each foot of setback interior to all building lines, an additional height of one foot shall be permitted, but in no event shall the total height exceed forty-five feet, except as otherwise provided in this Zoning Code.
   (e)   Minimum Lot Area and Lot Width. An Industrial Park District shall be required to contain a minimum of eighty acres of land area.
   All buildings or structures permitted in the Industrial Park District shall be located on a lot having a minimum area of one acre and a minimum frontage on a public thoroughfare of 150 feet.
   (f)      Yards Required.
(1)   Front yards. The depth of the front yard shall be not less than seventy-five feet on all minor streets. For lots fronting on streets shown as major thoroughfares on the Official Thorofare Plan of the City, the depth of the front yard shall be seventy-five feet plus one-half of the proposed right of way for such major thoroughfares as shown on the Official Thorofare Plan.
(2)   Access barrier. Within the required front yard and adjacent to the street right-of-way line, there shall be an open and unobstructed buffer strip of thirty feet in depth. Parking of vehicles in this buffer strip shall be prohibited. Except for accessways permitted herein, such buffer strip shall contain a curb or other suitable barrier against unchanneled motor vehicle ingress or egress and shall be continuous for the entire width of the lot adjoining the street or highway right-of-way line.
(3)   Accessways. No lot shall have more than two accessways to any one street or highway. The width of such accessway shall be not less than twenty feet nor more than forty feet. Insofar as practical, the use of common accessways by two or more uses shall be encouraged, to reduce the number of access points. The fronting of uses on a marginal service street shall also be encouraged.
(4)   Side and rear yards. There shall be a rear yard of not less than fifty feet and two side yards, each having a width of not less than twenty-five feet. Wherever an Industrial Park District adjoins any other district, there shall be side and rear yard areas of not less than 100 feet along the lot lines of such other district, and suitable planting shall be maintained in such area. Suitable planting shall mean a planting which will reach a height of at least seven feet within a two-year period after such planting is made, and which will effectively screen the Industrial Park District from the adjoining lots of any other use district.
(5)   Heliports; yards required. In addition to the yards provided herein, any heliport or part thereof lying wholly within an Industrial Park District shall provide peripheral strips, no less than 100 feet wide, interior from all building lines, and no structures above surface yard improvements or vegetation above a level of eight inches above ground shall be permitted thereon. The interior lines of such peripheral strip shall constitute the building lines of such heliports. All approach strips, landing pads and other facilities shall meet minimum requirements specified by the Federal Aviation Agency or other applicable agencies governing safe operation and procedure of aircraft.
   (g)   Percentage of Lot Coverage. No more than thirty percent of the lot area shall be covered by any main and accessory buildings.
   (h)   Off-Street Parking, Loading and Storage. Space for off-street parking of employees, customers and visitors shall be required in accordance with Chapter 1276.
   (i)   Signs. The provisions of Chapter 1274 shall govern in an I-3 District.
   (j)   Certificate of Occupancy and Building Permit. A certificate of occupancy shall be applied for before any building permit is issued for the construction or change in use of a building or use of land in any Industrial Park District.
   An application for a building permit and certificate of occupancy for a building or use of land shall be accompanied by:
(1)   A plot plan of land or parcel of land to be used, showing dimensions, location of all existing and proposed buildings, driveways, off-street parking areas, topography, abutting streets, railroads, highways, loading and unloading areas, key map, names of adjacent property owners, watercourses and other topographic features within 200 feet of the property lines.
(2)   Construction plans for all proposed buildings, walls and fences.
(3)   A description of the proposed industrial operation in sufficient detail to fully describe the nature and extent of the proposed use.
(4)   Plans or reports describing proposed treatment of any excess traffic condition, noise, glare, air pollution and treatment and handling of hazardous gases, liquids or other material.
(5)   Plans or reports showing proposed treatment and disposal of sewage and industrial waste.
(6)   Description of any fuel proposed to be used, including engineering plans for the control of any smoke which may be generated.
(7)   Additional data which may be required by the Planning Commission or Board of Zoning Appeals to ascertain conformance with the requirements of this Zoning Code.
   The Administrative Officer shall refer the application for the certificate of occupancy to the City Planning Commission for study and report to the Board of Zoning Appeals. Upon receiving the report from the City Planning Commission, the Board of Zoning Appeals shall approve or deny the issuance of the building permit or shall negotiate with the applicant for such proposed changes in the construction, use, storage, handling of materials or other matter which the Board may deem necessary in the best interests of the City. Upon reaching agreement with the applicant on such matters, the Board of Zoning Appeals shall issue the building permit to the applicant.
   A change or changes in the physical facilities or use permitted by a building permit shall occur only after the holder of such has obtained an amendment thereto allowing such change or changes.
   A certificate of occupancy for a building or use of land in this District may not be issued until the Administrative Officer finds that all of the provisions of this chapter have been met. Such certificate may be revoked by the Board of Zoning Appeals after hearing if the Board finds that the holder of the certificate has failed to comply with the development of approved plans.
   (k)   Streets, Sewers and Water Lines. All streets, sewers and water lines in any Industrial Park District shall meet City standards. As a condition precedent to the issuance of a certificate of occupancy, streets, sewers and water lines shall be installed or performance guaranteed in an approved manner and at grades and locations in street abutting lot lines as approved by the City Engineer. Where, however, not all or substantially all of a plot is to be utilized initially, the Board of Zoning Appeals shall authorize the postponement, until further improvements are to be made, of as much of the installation of streets, sewers and water lines and other improvements as is reasonable under the circumstances of the use to be made of the plot and the drainage and traffic problems of the area.
