As used in this Article, the following terms shall have the meanings indicated:
CLUSTER DEVELOPMENT
As a condition of approval of a subdivision plat or plats pursuant to this Article, the modification of the applicable zoning local law to provide an alternative permitted method of the development of such plat or plats to allow all of the development which could occur on a particular parcel of land to be developed on a portion of said parcel. In no case shall the number of building plots or dwelling units exceed the number which could be permitted, in the Board's judgment, if the land were subdivided into lots conforming to the minimum lot size and density requirements of this chapter.
ZONING DISTRICTS
Districts provided for in § 7-702 of State Village Law and Article III of this chapter.
A. 
The Trustees hereby authorize the Planning Board, simultaneously with the approval of a plat or plats pursuant to this Part 2, to modify applicable provisions of the local laws subject to the conditions hereinafter set forth and such other reasonable conditions as the Trustees may their discretion add hereafter. Such authorization shall apply to all lands within the Village. The purposes of this authorization shall be 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 conditions hereinabove referred to are as follows:
(1) 
This procedure may be followed at the discretion of the Board if, in the Board's judgment, its application would benefit the Village; provided, however, that in granting such authorization to the Board, the Trustees also authorize the Planning Board to require the applicant to submit an application which reflects such modification; in such case, the Trustees herein direct the Board to adopt rules and regulations setting forth the criteria pursuant to which such an application may be required.
(2) 
This procedure shall be applicable only 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 Board's judgment, if the land were subdivided into lots conforming to the minimum lot size and density requirements of the zoning applicable to the district or districts in which such land is situated and conforming to all other applicable requirements; provided, however, that where the plat falls within two or more districts with differing density requirements, the Board may approve in any one such district a cluster development representing the cumulative density as derived from the summing of all units allowed in all such districts.
(3) 
The dwelling units permitted may be, at the discretion of the Board, and subject to the conditions set forth by the Trustees, in detached, semidetached, attached or multistory structures.
(4) 
In the event that the application of this procedure results in a plat showing lands available for park, recreation, open space or other municipal purposes directly related to the plat, then the Board as a condition of plat approval may 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. The Trustees direct that such conditions be approved by the Trustees before the plat may be approved for filing.
B. 
The proposed site plan, including areas within which structures may be located, the height and spacing of buildings, open space and their landscaping, off-street open and enclosed parking spaces and streets, driveways and all other physical features as shown on said plan or otherwise described, accompanied by a statement setting forth the nature of such modifications, changes or supplementations of existing zoning provisions as are not shown on said site plan, shall be subject to review at the public hearing held pursuant to this Article.
C. 
On the filing of the plat in the Office of the County Clerk, a copy shall be filed with the Village Clerk, who shall make appropriate notations and references thereto in the Village Zoning Law or Map.
