Guarantee Of Improvements. Unless otherwise provided for in the conditions of a particular Planned Industrial District, no building permits or permits authorizing the occupancy or use of a building, facility, industrial or commercial establishment or service concern may be issued until required related off-site improvements are constructed or cash or a surety bond is posted covering their estimated cost as determined by the Department of Planning. This requirement shall not apply to foundation permits or permits necessary for the installation of required related off-site improvements. Required related off-site improvements shall include, but not be limited to, streets, sidewalks, sanitary and storm sewers, street lights and street trees. If a Planned Industrial District is developed in sections, the requirement shall also apply to all major improvements necessary to the proper operation and function of the section in question, even though such improvements may be located outside of the section in question.
