The Planning Board, in considering an application for the subdivision of land, shall be guided by the following planning and design development standards. These standards shall be considered to be minimum requirements.
Where the Planning Board finds that because of exceptional and unique conditions of topography, location, shape, size, drainage or other physical features of the site or because of the special nature and character of surrounding developments, the minimum standards specified herein would not reasonably protect or provide for the public health, safety or welfare, special engineering designs shall be required to protect the public health, safety and comfort by the Planning Board.
Where the Planning Board finds that, due to the special circumstances of a particular plat, the provision of certain required improvements is not requisite in the interest of the public health, safety and general welfare or is inappropriate because of inadequacy or lack of connecting facilities adjacent or in proximity to the proposed subdivision, it may waive such requirements subject to appropriate conditions.
To enable and encourage flexibility of design and development of land in such a manner as to promote the most appropriate use of land, to facilitate the adequate and economical provisions of streets and utilities and to preserve the natural and scenic qualities of open lands, the Planning Board may modify the residential zoning provisions simultaneously with the subdivision approval, subject to the following:
A. 
The owner shall make written application for the use of this procedure, which may be followed at the discretion of the Planning Board.
B. 
The owner shall submit a proposed site plan showing areas where structures will be located, the height and spacing of buildings, open spaces and their landscaping, off-street, open and enclosed parking spaces, streets, driveways and all other physical features of the proposed development.
C. 
The owner shall submit a statement setting forth the nature of such modifications, changes and supplementation of existing zoning provisions.
D. 
This procedure shall be applicable to lands zoned for residential purposes, and its application shall result in a permitted number of dwelling units which shall in no case exceed the number which could be permitted, in the Planning Board's judgment, if the land were subdivided into lots conforming to the minimum lot size and density requirements of the Zoning Ordinance applicable to the district in which such land is situated and conforming to all other applicable requirements.
E. 
At the discretion of and subject to any conditions which the Planning Board may impose, the dwelling units permitted may be detached, attached or multistory structures.
F. 
If this procedure results in a subdivision plat showing lands available for parks, open spaces or other municipal purposes, then the Planning Board, as a condition of plat approval, shall establish such conditions on the ownership, use and maintenance of such lands as it deems necessary to assure the preservation of such lands for their intended purposes.
G. 
Before any such modification is made in the zoning regulations, there shall be a public hearing on the proposed site plan, as required by law.
The standards and requirements of these Subdivision Regulations may be modified by the Planning Board in the case of a planned unit 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.
A. 
In granting waivers or modifications, the Planning Board shall require such reasonable conditions as will, in its judgment, secure substantially the objectives of the standards or requirements so waived or modified.
B. 
No such waivers may be granted if it would have the effect of nullifying the intent and purpose of the Zoning Ordinance,[1] the Master Plan or these subdivision regulations.
