The standards and requirements of these regulations may be modified by the Planning Board in the case of a plan and program for neighborhood unit or similar large-scale development which in its judgment provides adequate public spaces and improvements for the circulation, recreation, light, air, and service needs of the tract when fully developed and which also provides such covenants or other legal provisions as will assure conformity to and achievement of the plan. This plan should conform to the Planned Development District in Chapter
160, Zoning.
In granting waivers or modifications the Planning Board may require
such reasonable conditions as will in its judgment secure substantially the
objectives of the standards or requirements so waived or modified.
