* | In computing the number of required parking spaces, the following shall apply: | |
1) | Where fractional spaces result, the required number shall be construed to be the next highest whole number. | |
2) | The parking space requirements for a use not specifically mentioned herein shall be the same as required for a use of similar nature to those enumerated in Exhibit 40-9-1 or 40-9-2 as determined by the Municipal Agency. | |
3) | If there is no use enumerated herein sufficiently similar to the use proposed to enable the Municipal Agency to establish rational parking requirements, the Municipal Agency may, in its discretion, direct the applicant to furnish the Municipal Agency with such data as may be necessary to enable the Municipal Agency to establish rational parking requirements. | |
** | Bar, Restaurant, or similar uses shall be calculated separately. | |

Notes: | |
|---|---|
(1) | Bituminous Stabilized Base Course may be substituted for Gravel Base Course on a 1 inch to 3 inch ratio. |
(2) | If Subgrade is approved as adequate by the Engineer, Gravel Base Course may be completely eliminated and Bituminous Stabilized Base Course may be substituted on a 1 inch to 3 inch ratio. |
(3) | Gravel Base Course may be reduced to 3 inches minimum if Subbase is provided. |
(4) | Subbase may be required depending on Subgrade soils, ground water elevations and other variables. |
(5) | Portions of Parking Areas and Aisles likely to be subjected to significant heavy truck traffic shall meet the standards for local streets. |

Illumination Guidelines for Street, Parking, and Pedestrian Areas |
IES Lighting Handbook definitions: | |||
1. | Area classification: | ||
Commercial. That portion of a municipality in a business development where ordinarily there are large numbers of pedestrians during business hours. | |||
Intermediate. That portion of a municipality often characterized by a moderately heavy nighttime pedestrian activity such as in blocks having libraries, community recreation centers, large apartment buildings or neighborhood retail stores. | |||
Residential. A residential development, or a mixture of residential and commercial establishments, characterized by a few pedestrians at night. This definition includes areas with single family homes, townhouses and/or small apartment buildings. | |||
2. | Activity level: | ||
High activity. Major league athletic events cultural or civic events, and major regional shopping centers. | |||
Medium activity. Fast food facilities, area shopping centers, hospital parking areas, transportation parking (airports, etc.), cultural, civic or recreational events, and residential complex parking. | |||
Low activity. Local merchant parking, industrial employee parking, educational facility parking. | |||
3. | Bikeway classification: | ||
Type A bikeway. A strip within or adjacent to a public roadway or shoulder, used for bicycle travel. | |||
Type B bikeway. An improved strip identified for public bicycle travel and located away from a roadway or its adjacent sidewalk system. | |||
2. | Fire Hydrants. | ||
(a) | Size, type, and installation of hydrants shall be in accordance with local practice, or shall conform to the American Water Works Association standard for Dry Barrel Fire Hydrants (AWWA C-502). Hydrants shall have at least three outlets; one outlet shall be a pumper outlet and other outlets shall be at least 2 1/2 inch normal size. Street main connections should be not less than six inches in diameter. Hose threads on outlets shall conform to National Standard dimensions. A valve shall be provided on connections between hydrants and street mains. All pipe, fittings, and appurtenances supplying fire hydrants shall be AWWA- or ASTM-approved. | ||
(b) | All fire hydrants shall conform to the color-code system as shown in Exhibit 40-9-12. | ||
Exhibit 40-9-12: Color Code System for Fire Hydrants | |
|---|---|
Class "A" | 1,000 gpm or greater and water mains of 10 inches and greater — green caps and bonnets |
