The proposed streets shall conform in width and alignment with those
shown on the master or study plan of the town, as adopted, in whole or in
part, by the Planning Board, except as the same purposes may be shown, to
the satisfaction of the Board, to be better served by a modification thereof
in the general area of the proposed subdivision.
Before approval of a plan, the Planning Board may also, in proper cases,
require the plan to show a park or parks or open areas suitably located for
playground or recreational purposes or for providing light and air. The park
or parks shall not be unreasonable in area in relation to the land being subdivided
and to the prospective uses of such land. The Board may, by appropriate endorsement
on the plan, require that no building be erected upon such park or parks without
its approval.
A variation of these design requirements may be permitted when, in the
opinion of the Planning Board, topography or other physical consideration
necessitates such variation.
