(B) Computation. When determination of the number of off-street parking spaces required by this chapter results in a requirement of a fractional space, any fraction of one-half or less may be disregarded, while a fraction in excess of one-half shall be counted as one parking space.
(C) Collective provision. Off-street parking facilities for separate uses may be provided collectively if a total number of spaces so provided is not less than the sum of the separate requirements for each use, and provided that all regulations governing location of accessory parking spaces, in relation to the use served, are adhered to.

No driveway across public property at the right-of-way line shall exceed a width of 25 feet.

(4) Lighting. Any lighting used to illuminate off-street parking areas shall be directed away from residential properties in such a way as not to create a nuisance, and in a parking area containing 40 or more parking spaces the light shall be extinguished one-half hour after the close of business, except as may otherwise be permitted or required by the Board for maintaining illumination with less candlepower after the time specified above.
