A sketch plan review is recommended prior to submission of a formal application for subdivision approval. The sketch plan review is intended to reduce the review time for Planning Board consideration of proposed subdivisions by allowing early review of the plan by the Planning Board. Upon the request for sketch plan review, the Planning Board shall notify the applicant of the place, date, and time of the meeting at which the sketch plan is to be considered. The applicant or the applicant's representatives shall be present at the meeting to discuss the application. The sketch plan review shall be limited to a review of the basic concept of the proposal with respect to the minimum area, yard and bulk requirements of the district in which the property is located, and to identify problems with meeting the requirements of this chapter which might occur during formal Planning Board consideration. The sketch plan review and consultation shall be nonbinding. After the sketch plan review, nothing herein shall be construed to prevent an applicant from submitting a formal application for subdivision approval to the Planning Board. Although not required, applicants are encouraged to commence discussions with the owners of land abutting or in proximity to the project site to ascertain local concerns and local development issues early in the project design process.
A. 
All applicants wishing to be placed on the Planning Board agenda for sketch plan review shall contact the Planning Board with the request. Requests are placed on the agenda in the order they are received.
B. 
Documentation. Maps showing the property boundaries, general topographic information, approximate location of wetlands and the proposed lot arrangement and locations of new streets must be submitted but need not be in final form. All surveys must bear the signature and seal of a licensed professional engineer or land surveyor. An environmental assessment form must be brought to the same conferences to be reviewed by the Planning Board.
C. 
Town Engineer, Planning Consultant and Highway General Foreman. Prior to formally submitting the application for preliminary subdivision approval, the applicant, or his or her duly authorized representative, should contact the Highway General Foreman, the Town Engineer and/or the Town Planning Consultant to discuss the proposed subdivision layout and its potential environmental impacts.
D. 
Health Department. The sketch plat should also be discussed with the Westchester County Health Department, which must eventually approve any final subdivision plat. Particular attention should be paid to the area, grade and type of soil of proposed building sites, and the proper amount of land area for on-site water supply and sewage disposal facilities.
E. 
Soil and Water Conservation District. The Planning Board may also refer a sketch plat to the Westchester County Soil and Water Conservation District for its review and comments regarding soil types, stormwater drainage, resource conservation and suggested erosion control practices.
F. 
Conservation Board. Where parcels are 10 acres in area or greater or where such parcels are designated on the Town's Open Space Inventory Map, or where activities are shown occurring in or adjacent to any controlled areas as defined in Chapter 340, Wetlands and Watercourse Protection, the Planning Board may refer a sketch plat to the Conservation Board for its review and comment.
G. 
Architectural Review Board. The Planning Board may refer a proposed subdivision to the Architectural Review Board, which shall, within the powers of its mandate, review such subdivision to identify scenic views, important natural features, significant land forms, potential for solar energy exposures and potential building sites.
H. 
Planning Board. Prior to formally submitting the application for preliminary plat approval to the Planning Board, the applicant, or his or her duly authorized representative, shall meet with the Planning Board to discuss the proposed subdivision layout and its potential adverse environmental impacts, if any.
I. 
Field trip. After the initial conference, the Planning Board may schedule a field trip to the proposed subdivision site. Prior to this field trip, the Planning Board may require that the center line of any proposed road, common driveways and specific lot locations be staked. At the request of the Planning Board, the applicant, or his or her duly authorized representative, shall attend the field trip.
J. 
Planning Board recommendations. The Planning Board shall advise the applicant, or his or her duly authorized representative, of the additions and modifications, if any, which should be made if an application for preliminary subdivision approval is to be submitted.

A. 
Application and fee. Prior to the filing of an application for the approval of a final plat for a subdivision, the applicant shall submit an application for approval of a preliminary subdivision plat. All applications for preliminary subdivision approval shall be in writing and on forms and in such quantity as may be prescribed by the Planning Board, together with a fee as set forth in the Master Fee Schedule.[1] The preliminary plat shall in all respects comply with the requirements set forth in this chapter and the provisions of §§ 276 and 277 of the Town Law, except where a waiver of such requirements may be specifically authorized by the Planning Board.

[1]
Editor's Note: See Ch. A370, Master Fee Schedule.
B. 
Purpose. The preliminary layout, the application, and all supporting documents for a proposed subdivision constitute the material to be officially submitted to the Planning Board. On the basis of the general design of the subdivision and any proposed or required public improvements, the Planning Board will indicate its approval or disapproval of the preliminary plat prior to the time that the final plat, including the design and detailing of the improvements and utilities, is completed. Approval of the preliminary layout does not constitute an approval of the final plat, nor shall it be considered a valid basis for filing of the preliminary plat with the County Clerk, or the construction of site improvements, or for other commitments which depend upon detailed design characteristics.
C. 
Receipt. An application submitted under this section shall be deemed received at the next regular meeting of the Planning Board at which the application is to be considered. An application shall be placed on the Planning Board agenda only upon payment of the application fee as set by the Master Fee Schedule,[2] along with an environmental assessment form and the number of copies of the plat map as specified by the Planning Board.

The applicant or his duly authorized representative shall attend meetings of the Planning Board at which the application is considered to discuss the preliminary plat. Although not required, applicants are encouraged to commence discussions with the owners of land abutting or in proximity to the project site to ascertain local concerns and local development issues early in the project design process.
E. 
Study of preliminary plat. The Planning Board shall study the proposed preliminary plat, taking into consideration the goals and policies of the Town Comprehensive Plan for the district in which the parcel is located, the needs of the community, the requirements of Chapter 355, Zoning, and this chapter, and the best use of the land being subdivided. Particular attention shall be given to the arrangement, location and width of streets, their relation to the topography of the land, water supply, sewage disposal, vehicular and pedestrian access, preservation of natural resources, relationship to improvements on adjacent and neighboring land, drainage, lot sizes and arrangement, and the future development of adjoining lands as yet unsubdivided, including those lands depicted on the Official Map.
F. 
Look-back provision. Within any ten-year period, no more than 49 lots may be created either simultaneously or sequentially from a parent parcel for which both central sewer and water services do not exist or have not been provided. Should more than that total number of lots be applied for within 10 years of the date of subdivision approval involving the parent parcel, the Planning Board may require the applicant to include a plan for providing central sewer and water services to the previously subdivided lots at no additional cost to their present owners as part of the new application for subdivision approval.
G. 
Compliance with the State Environmental Quality Review Act. A preliminary plat application shall not be considered complete until a negative declaration has been filed or until a notice of completion of the draft environmental impact statement has been filed in accordance with the provisions of the State Environmental Quality Review Act.
