ARTICLE VI

OFF-STREET PARKING AND LOADING; LANDSCAPING

§ 40-6-1 PURPOSE.

   The purpose of this article is to alleviate or prevent congestion of the public streets, and so promote the safety and welfare of the public by establishing minimum requirements for the off-street parking and loading and unloading of motor vehicles in accordance with the use to which property is put.
(Ord. 1070, § 40-6-1, passed 7-20-1998)

§ 40-6-2 SCOPE AND REGULATIONS.

   The off-street parking and loading provisions of this code shall apply as follows:
   (A)   For all buildings and structures erected and all land uses established after the effective date of this code, accessory parking and loading facilities shall be provided as required by the regulations of the district in which such buildings or uses are located. However, where a building permit has been issued prior to the effective date of this code, and provided that construction is begun within one year of such effective date and diligently prosecuted to completion, parking and loading facilities as required hereinafter need not be provided.
   (B)   When the intensity of use of any building, structure, or premises shall be increased through addition of dwelling units, gross floor area, seating capacity, or other units or measurement specified herein for required parking and loading facilities as required herein shall be provided for such increase in intensity of use.
   (C)   Whenever the existing use of a building or structure shall hereafter be changed to a new use, parking or loading facilities shall be provided as required for such new use. However, if the said building or structure was erected prior to the effective date of this code, additional parking or loading facilities are mandatory only in the amount by which the requirements for the new use would exceed those for the existing use if the latter were subject to the parking and loading provisions of this code.
(Ord. 1070, § 40-6-2, passed 7-20-1998) Penalty, see § 1-1-19

§ 40-6-3 EXISTING PARKING AND LOADING FACILITIES.

   Accessory off-street parking or loading facilities which are located on the same lot as the building or use served and which were in existence on the effective date of this code or were provided voluntarily after such effective date shall not hereafter be reduced below, or if already less than, shall not further be reduced below the requirements of this code for a similar new building or use.
(Ord. 1070, § 40-6-3, passed 7-20-1998) Penalty, see § 1-1-19

§ 40-6-4 DAMAGE OR DESTRUCTION.

   For any conforming building or use which is in existence on the effective date of this code, which subsequent thereto is damaged or destroyed by fire, collapse, explosion, or other cause, and which is reconstructed, reestablished, or repaired, off-street parking or loading facilities need not be provided, except that parking or loading facilities equivalent to any maintained at the time of such damage or destruction shall be restored or continued in operation. However, in no case shall it be necessary to restore or maintain parking or loading facilities in excess of those required by this code for equivalent new uses or construction.
(Ord. 1070, § 40-6-4, passed 7-20-1998)

§ 40-6-5 CONTROL OF OFF-SITE PARKING FACILITIES.

   When required parking facilities are provided on land other than the zoning lot on which the building or use served by such facilities is located, they shall be and remain in the same possession or ownership as the zoning lot occupied by the building or use to which the parking facilities are accessory. No such off-site parking facilities shall be authorized and no occupancy permit shall be issued where the plans call for parking facilities other than on the same zoning lot until and unless the Zoning Board of Appeals has reviewed the plans and heard the applicant and made findings that the common ownership or possession of the zoning lot and the site of the parking facilities are reasonably certain to continue, and that the off-site parking facilities will be maintained at all times during the life of the proposed use or building.
