6. No luminaire or lamppost shall exceed thirty feet (30') in height except those provided in an LI, GI, PAD, or SIU district or those illuminating recreational sports fields or arenas during hours of use.
7. In parking lots containing more than four (4) light poles, the light poles shall be numbered in a manner that makes them easily identifiable. (Ord. 2013-20)
L. Minimum Off Street Parking Lot Stall And Module Dimensions:
1. Minimum Stall And Module Dimensions: All public and private off street parking lots shall meet the following minimum stall and module dimensions as shown in table A, "Parking Stall And Module Dimensions", of this section.
TABLE A
PARKING STALL AND MODULE DIMENSIONS
Angle | Stall Type | Width | Vehicle Projection (A) | Aisle (B) | Typical Module (C) | Interlock Reduction (D) | Vehicle Overhang (E) |
0° | PAR | 21'0" | 8'0" | 10'0" | 26'0" | - | 2'0" |
45° | STD | 9'0" | 18'10" | 13'8" | 51'6" | 2'3" | 2'3" |
60° | STD | 9'0" | 18'11" | 15'8" | 53'8" | 1'6" | 2'6" |

a. The parking module (dimension C per figure A of this section) shall be computed by adding the vehicle projection in the parked stall (dimension A) to the required aisle width (dimension B) for that angle of parking. The module shall be the clear dimension between walls or other obstructions except that columns of a combined maximum dimension of two feet (2') may protrude into a module with a parking angle between forty five degrees (45°) and seventy five degrees (75°) up to two feet (2') from the face of the wall. A vehicle overhang (dimension E) will be allowed as shown in table A of this section to reduce the overall paved module. No vehicle overhang shall project into any sidewalk or landscaped area.

2. Design Standards For Parking And Circulation For Miniwarehouses: Before the development, operation or improvement of a miniwarehouse project, a zoning certificate shall be obtained for same. No permit shall be issued until the plans and specifications of the development have been submitted to the administrative official and it is determined that all of the following standards will be met:

For one-way traffic serving no cubicles, a twelve foot (12') minimum driveway width is required.
b. Required driveway shall be surfaced to meet the standards required in the zoning district in which the miniwarehouse is to be located.
c. Off street parking spaces shall be required in accordance with this section for the use of current prospective customers at the project office and for the manager's quarters (if provided). If more than four (4) spaces are required for the project office, such spaces shall be developed in accordance with this section as required for surface parking lots.

e. Where parking structures are to be used after dark, a system of lighting shall be provided in accordance with this section.
(1) Generally, the maximum height above ground level of exterior lights shall be thirty feet (30'), excepting those lights required to illuminate any roof deck parking areas. Such roof deck lights shall be shielded and positioned to direct light only on the roof deck and not on adjacent areas.
