Cross reference— Use, possession and storage of explosives, Ch. 13; circuses and carnivals permitted in IU Districts without public hearing, § 33-13(f).

Any person, firm, corporation or other legal entity desiring to use any property or premises situated in an IU-3 District for the manufacture, assembly, processing or packaging of any article or matter enumerated in Section 33-264(3), or for the storage of relatively large quantities of such article or matter (not to include storage where storage is relatively small and incidental to the use of small quantities of such article or matter in connection with manufacture, processing or use permitted in more restrictive districts), or manufacture, assembly, processing, packaging or storage of similar articles or matter, or for any use or operation enumerated in said Section 33-264(3) or for similar use or operation, shall file with the Director a written application setting forth a full description of the proposed use or occupancy, and accurate legal description of the property or premises, a description of the structure or structures to be constructed or occupied, satisfactory proof that the proposed use will conform to the requirements of the Miami-Dade County Pollution Control Ordinance, and such other information as may be reasonably required by the Director, who shall determine from such information, whether or not the proposed use will, in fact, create objectionable influences ordinarily associated with the general type of such uses. If it is found that such use because of the method of operation, or type of materials used, the usual degree of hazardous conditions will not be created, the Director may assign the use to the IU-3 District or to a less restrictive zoning district. However, if it is determined that the high hazards usually anticipated in connection with the uses listed involving fire, explosions, noise, vibration, dust or emissions of smoke, odors, or toxic gases, or other hazards to public health, safety or welfare will be created, the Director shall require approval as result of a public hearing before such use is permitted. Upon filing of the application, the Director shall transmit such application, together with his recommendations, to the Community Zoning Appeals Board, who shall consider the application in accordance with the zoning procedure prescribed by article XXXVI of this chapter, and transmit its recommendations to the County Commission. Provided, however, no use specified in Section 33-264(3) shall be established within five hundred (500) feet of any RU or EU District except after approval after public hearing. Provided, that the spacing limitation shall be two hundred fifty (250) feet if the use is confined within a building and an exterior wall or walls of the building located on the establishment is not penetrated with any openings directly facing the RU or EU District. It is further provided that, except for exterior uses, such distances shall be measured from the closest point of the subject use in the building to the RU or EU District. In connection with exterior uses, the distance of five hundred (500) feet shall be measured from the closest point of the IU District to the RU or EU District. For purposes of establishing such distances, the applicant for such use shall furnish a certified survey from a registered surveyor, which shall indicate such distances. In case of dispute, the measurement scaled by the Director of the Department of Planning and Zoning shall govern.

(Ord. No. 57-19, § 25(B), 10-22-57; Ord. No. 69-51, § 3, 9-3-69; Ord. No. 96-129, § 1, 9-10-96; Ord. No. 98-125, § 21, 9-3-98; Ord. No. 00-74, § 1, 6-6-00)

The premises used by gasoline, oil and petroleum storage tanks shall be surrounded by an unpierced fire wall or dike of such height and dimensions as to contain the maximum capacity required by current applicable Miami-Dade County codes. Where an abandoned rock pit is located in an IU-2 or IU-3 District, a permit may be issued to use such pits for oil storage tanks in which dikes may be omitted if the pit has the required capacity. All storage tanks and adjacent structures shall meet the requirements of the current applicable Miami-Dade County codes.

The foregoing paragraph requiring an unpierced fire wall or dike shall not apply to storage tanks containing liquefied petroleum, commonly known as bottled gas; such tanks may be erected without said wall or dike.

(a)

Landscaped open space. A minimum of ten (10) percent of the net lot area of the site shall be developed as landscaped open space; provided, however, that an industrial-zoned site that abuts residentially zoned or developed property shall provide fifteen (15) percent of the net lot area as landscaped open space. It is further provided, however, that if the industrial-zoned site abuts property which is depicted as "Industrial & Office" on the Land Use Plan map of the Comprehensive Development Master Plan, is zoned GU and no building permit has been issued for a residence at the time of the approval of the building permit for the industrial use, the landscape open space requirement shall be ten (10) percent of the net lot area. Said landscaped open space may include entrance features, greenbelts, unpaved passive and active recreation areas, and other similar landscaped open space at ground level. Open space areas may also include tree preservation zones of "natural forest communities" as defined in Section 26B-1, Code of Miami-Dade County. Tree preservation zones shall be delineated on all plans submitted to Miami-Dade County for site plan review under Section 33-266.3 of the Code of Miami-Dade County, for the purpose of determining overall preservation area and percent of overall landscaped area. The requirements contained herein do not replace or substitute for any requirements contained within Chapter 18A, Code of Miami-Dade County.

(b)

Greenbelts. Continuous, extensively planted greenbelts, penetrated only at approved points for ingress or egress to the property, shall be provided along all property lines abutting public rights-of-way or properties zoned residential, in accordance with the following minimum standards:
