A. No structure or building shall be erected or placed on a lot nor shall any use be made of a lot:
1. Wherein the dwelling floor area to lot area ratio is greater than hereinbefore specified by the regulations of the zoning district in which such structure, building or use is located;
2. Wherein the total building area to lot area ratio is greater than hereinbefore specified by the regulations of the zoning district in which such structure, building or use is located. (This regulation applies both to buildings wherein dwellings are located and those not having dwelling units associated.)
B. For the purpose of this title, the lot area shall be measured from the base setback line.
C. A lot shall be at least as wide as the specified minimum average width for a distance of at least one half the length of the lot.
D. No lot area shall be reduced by any means so as to create a lot of less than the required size, or so that the existing offsets, setbacks, open space or lot area would be reduced below that required by the regulations for the zoning district in which such lot is located.
E. Where a lot has less land area or width than required for the zoning district in which it is located, and was of record at the time of the passage of this zoning ordinance, lot may be used for any purpose permitted in such zoning district, but not for residential purposes for more than one family; provided, however, that in no case shall the setback, offset or open space requirement be reduced except by written approval of the zoning administrator.
F. The requirements of this section may be waived by the zoning administrator in the case of a “well lot” parcel. (Ord. 525 § 1(part), 1989).

No structure or building shall be erected, structurally altered or placed on a lot so as to reduce the usable open area of such lot to less than that hereinbefore specified by the regulations for that zoning district in which such lot is located. (Ord. 525 § 1(part), 1989).

To be considered usable, such open area shall be readily accessible and of a size and shape which can be reasonably considered to provide for the amenities and necessities of light, air, play space, drying yard, garden, orchard, vineyard or similar open use. Cropland, pasture, orchard, garden and woodland may be included in computing such open area. (Ord. 525 § 1(part), 1989).

No part of the open area provided for any building or structure shall be included as part of the open area required for another building or structure, except as hereinbefore provided for PRD planned residential development district, PRA planned recreation area district, PSC planned shopping center district, or PIP planned industrial park district. (Ord. 525 § 1(part), 1989).
