1343.06 REQUIRED DEVELOPMENT STANDARDS.
   All permitted, accessory, and special permit uses in all industrial districts shall be subject to the following development standards.
   (a)   Building materials. All buildings or other structures erected in industrial districts shall be fireproof and constructed of masonry or other strong and architecturally acceptable materials.
   (b)   Heights of structures. Any principal structure erected within an industrial district shall not exceed forty feet in height, measured from the average elevation of the finished lot grade at the front of the building to the roof-line. However, this height may be exceeded for water towers or tanks, standpipes, penthouses or structures for housing elevators or related equipment, stairways, ventilating fans or other equipment required to operate or maintain the buildings; fire or parapet walls; cooling tanks or towers; signs on top of parapets; flagpoles, chimneys, storage and/or mixing towers; and similar structures. But no structure or any space above the height limit shall be allowed for the purpose of creating additional office or production floor space or for sign display other than the permitted signs on top of the parapet.
   (c)   Site coverage. No buildings or other structures should be built or maintained which, in the aggregate, cover more than sixty-five percent (65%) of the total land area.
   (d)   Off-street parking. It shall be the responsibility of each occupant industry to provide off-street parking facilities for employees, visitors, trucks, and trailers, as per the requirements of Article 1359. Parking shall not be provided in the required front yard. Parking requirements may be modified where the availability of parking areas within the district will provide sufficient parking spaces.
   (e)   Site landscaping improvements and maintenance. Any area within a building site that is landscaped shall be done attractively with lawn, trees, shrubs and other plantings. All landscaped areas shall be properly maintained thereafter in a well- kept condition. Front yards of building sites shall be maintained in grass except walks, drives, plantings, and flagpoles. All walks, driveways, and parking areas shall be surfaced with bituminous, concrete, or equivalent coatings. Occupant industries shall have the responsibility of extending driveways to existing or projected streets, at their own expense, even though parts of this construction are within the street right of way. Unpaved parts of the site shall be maintained in grass and landscaped, including any such property that may be in a street, rail, or utility right-of-way. Maintenance of individual building sites within the district shall be the responsibility of the occupant industry, and the premises, buildings, and all improvements shall be kept in a safe, clean, healthful, and presentable condition at all times. The removal of undergrowth, weeds, debris, rubbish, trash, excess dirt, industrial wastes or garbage, and any other unsightly material from a building site shall be done or arranged to be done by the occupant industry.
   (f)   Loading facilities. The maneuvering of trucks and trailers shall be confined to the premises of each occupant industry. Minimum requirements for off-street loading facilities shall be one loading space at least fourteen feet by sixty feet with a fifteen- foot height clearance if covered; total depth of the off-street maneuvering apron and truck position at dock shall be a minimum of 115 feet. The number of truck loading docks will be dependent upon the nature of the industry and types of transport service needed.
   (g)   Signs and outdoor advertising signs shall be permitted and regulated pursuant to Article 1359.
   (h)   Outside storage. Outside storage shall not be permitted. Where necessary to temporarily store finished or semi-finished products or other materials outside the plant building, the rear part of the property shall be used for such storage, and the storage area shall be screened by a fence at least six feet in height. All fencing for screening, security, or other purposes shall be attractive in appearance and be of an all-metal industrial type of galvanized or nonferrous material.
   (i)   Drainage plan. The applicant or occupant of the property shall submit for review and approval a drainage system plan for controlling storm and surface water runoff, with special emphasis on controlling the drainage on off-street parking and loading areas.
