Upon obtaining a special use permit according to the provisions of §
190-37, the requirements concerning lot area, frontage, side yards, and coverage may be modified for a development of not less than three acres, provided that the maximum density of the overall development is not greater than that normally allowable in the district in which it is located. Such land as may be made available under this section shall be devoted to common purposes for all residents, including, but not limited to, a park, playground or garden for the use of surrounding residents.
Other provisions of this chapter notwithstanding,
nothing shall prohibit a lot of less area than that required for a
single-family dwelling, provided that all other provisions of this
chapter are complied with, when such lot, on May 28, 1962, was held
under separate ownership or lesseeship from the adjoining lots.
Whenever a lot upon which exists a building
or structure is changed in size or shape so that the area and yard
requirements of this chapter are no longer complied with, such building
shall not thereafter be used until it is altered, reconstructed or
relocated so as to comply with such requirements. The provisions of
this section shall not apply when a portion of a lot is taken for
a public purpose.
