Unenclosed storage of personal property is permitted in this district in any area other than any portion of any required front setback area, any required exterior side or rear setback area of corner lots, rear setback area of double frontage lots and any unimproved parcel or any unimproved right-of-way of any public street, in which areas such storage is prohibited. In those prohibited areas, one or more of the items listed in subsections (b)(1) through (6) of this Section may be stored so long as such storage is not for any period of time in excess of five consecutive days and not in excess of a total of eighteen days in any calendar year. For example, if multiple items listed in subsections (b)(1) through (6) of this Section are stored concurrently in the prohibited areas for five consecutive days, such storage shall constitute a total of five days of the eighteen days allowed per calendar year. On the other hand, if, for example, a boat is stored for four consecutive days and subsequently a recreational vehicle is stored for three consecutive days, such storage shall constitute a total of seven days of the eighteen days allowed per calendar year.

Application for such storage permits shall be in writing, on forms furnished by the City and shall include a site plan showing the area of the requested storage. Any permit issued pursuant thereto shall be in writing, shall describe the personal property to be stored, and the location and time limit of the storage.
