A. 
Whenever any subdivision is proposed within the territorial jurisdiction of the Board and before any permit for the development of such land or for the erection of a structure thereon may be granted, the owner or his authorized agent shall apply for and secure approval of the proposed subdivision in accordance with this chapter. Three principal steps are involved, namely:
(1) 
Preapplication.
(2) 
Preliminary layout.
(3) 
Subdivision plat.
B. 
The Planning Board shall engage the services of a professional planner to make recommendations to it in connection with the planning and development of any parcel, and the fees for such planning advice shall be paid by the applicant.
A. 
Purpose. The purpose of the preapplication procedure is to afford the subdivider an opportunity to consult early and informally with the Board's representative before preparation of the preliminary layout and before formal application for its approval, in order to save time and unnecessary expense.
B. 
Meeting with representative. Prior to filing an application for tentative approval of the preliminary layout, the subdivider should meet with the authorized representative of the Board to discuss his sketch plan, which shall comply with the requirements of § 143-42 and the requirements for improvements and public facilities and services. The step does not require a formal application, a fee or the filing of a plat with the Board. Any preapplication meeting shall require a letter request to the Board presented at least 21 days prior to the meeting date.
C. 
Before preparing a sketch plan or attending the initial conference, the subdivider should familiarize himself with the regulations, standards and requirements contained herein. He should discuss, with the Village's authorized representative, the requirements as to general layout of streets, lots and reservations and similar matters, and with the Engineer, street improvements, drainage, sanitary waste disposal design, water and like matters, as well as the availability of existing services.
A. 
Application, fee and deposit. If the subdivider shall request the consideration by the Board of a preliminary layout, 10 copies of the preliminary layout, which shall in all respects comply with this chapter, shall be presented to the Clerk at least 21 days prior to the meeting of the Board at which it is to be considered. The preliminary layout shall be accompanied by the applicable fee and deposit, payable to the Village, in the amounts appearing in the fee schedule established by the Board of Trustees. Upon receipt of the preliminary layout and payment of the fee and deposit, the Clerk shall forthwith deliver the preliminary layout to the Board.
B. 
Study of preliminary layout. It is recommended that the subdivider or his representative attend the Board meeting when the preliminary layout is considered. The Board will study the practicability of the preliminary layout, taking into consideration the requirements of Article III. If the Board considers it appropriate the Board may hold a public hearing in a preliminary layout proposal.
C. 
Staking of proposed streets and field trip. To facilitate study of the preliminary layout in the field, the Board or its representative may require the subdivider to stake certain roads at intervals of 50 feet along their center lines. Each stake shall be marked for ready identification on the preliminary layout and shall show the approximate height of any proposed cut or fill at that point. The Board may schedule a field trip to the site, and the proposed subdivider should attend.
D. 
Action on preliminary layout. Following review of the preliminary layout and the other material submitted in accordance with this chapter and discussion with the subdivider of changes deemed advisable and the kind and extent of improvements to be made by him, the Board may authorize preparation of the subdivision plat in accordance with the preliminary layout as submitted, require stated modifications of the preliminary layout and authorize preparation of the subdivision plat as modified or disapprove the preliminary layout entirely, giving the reasons therefor.
E. 
Notation of action. The action of the Board shall be noted on two copies of the preliminary layout, referenced and attached to any changes or conditions required. One copy shall be returned to the subdivider and the other copy retained by the Board.
F. 
Effect of authorization. Authorization shall be deemed a tentative approval of the design of the preliminary layout and shall be a guide to the subdivider in preparing the subdivision plat.
G. 
Any subdivision at the Board's discretion shall be subject to review as a cluster design as an alternative consideration in accordance with the requirements of this chapter and Village Law § 7-738.
A. 
Subdivision plat requirements. The subdivision plat shall conform substantially to the preliminary layout as tentatively approved by the Board and to the requirements of § 143-45. If desired by the subdivider, the subdivision plat may constitute only that portion of the tentatively approved preliminary layout which he proposes to file and develop at the time; provided, however, that such portion shall conform to all requirements of this chapter and provided further that such portion abuts at least one street duly placed upon the Official Map, which street shall be improved to the satisfaction of the Board.
B. 
Number of copies and time for submitting application. Ten copies of the subdivision plat, together with 10 copies of the construction plans and all other items required by this chapter, shall be prepared as specified in § 143-45 et seq. and shall be filed with the Clerk within six months after the date of authorization to prepare the subdivision plat; otherwise such authorization shall expire unless an extension of time is applied for in writing within said six-month period and thereafter granted by the Board.
C. 
Application and submission date. Application for approval of the subdivision plat shall be filed by the owner or by his duly authorized agent in writing with the Clerk at least 21 days prior to a scheduled regular monthly meeting of the Board. The subdivision plat shall be deemed to be officially submitted upon the closing of the public hearing held thereon.
D. 
Endorsement of Suffolk County Department of Health Services. Proposed water supply and sanitary waste disposal facilities for the land to be subdivided shall be approved by the Suffolk County Department of Health Services.
E. 
Approval of New York State Department of Environmental Conservation. To the extent required by law, proof of approval of the New York State Department of Environmental Conservation shall be supplied to the Board with any plat.
F. 
Approval by other planning authority. Pursuant to §§ 239-m and 239-n of the General Municipal Law, some subdivision applications require referral to the Suffolk County Planning Commission.
G. 
Public hearing. Upon the filing of the application for approval, together with the subdivision plat, the construction plans and all documents, consents, approvals and other items required by this chapter and upon payment of the necessary fees, the Clerk shall cause to be advertised a notice of public hearing at least once in the official newspaper of the Village at least 10 days before such hearing, shall cause to be posted a copy of the notice of hearing on the official Village bulletin board at least five days before such hearing, and shall provide a copy of the notice of public hearing to the applicant, who shall mail a copy thereof by certified mail to each owner of land abutting or across the street from the land shown on the subdivision plat not less than seven days prior to the date of the hearing and who, prior to the hearing shall file with the Clerk an affidavit of such mailing. No hearing may be held until the affidavit of mailing shall have been filed as herein required. If in its opinion good cause appears therefor, the Board may adjourn the hearing to a subsequent regularly scheduled meeting of the Board.
H. 
Action on subdivision plat. Within 45 days after conclusion of the public hearing, the Board shall consider the matter and shall approve, modify and approve or disapprove the subdivision plat by a resolution which shall set forth, in detail, any conditions to which approval is subject or the reasons for disapproval.
I. 
Revision of subdivision plat. The subdivider will be given a copy of the Board's resolution and, in the event that modifications are required, he shall revise the subdivision plat and construction plans to conform thereto.
After completion of the subdivision plat and construction plans in accordance with the Board's resolution, the original tracing and two prints of each shall, within the time specified in said resolution or if no time is specified, within 30 days, be filed with the Clerk for final review by the Board. Approval of the subdivision plat shall be endorsed thereon as follows:
A. 
When bonds are filed, approval of the plat shall be endorsed thereon after the bonds have been approved and filed and all of the conditions of the Board's resolution pertaining to the plat have been satisfied.
B. 
When no bond is filed, approval of the plat shall be endorsed thereon after all conditions of the Board's resolution have been satisfied and all required improvements completed to the satisfaction of the Board.
C. 
Number of copies to be signed. Approval of the Board shall be noted on the subdivision plat by the Clerk, who shall sign the tracing cloth original of the subdivision plat, which will be returned to the subdivider, and one print of the plat which will be retained by the Board.
In accordance with the Village Law and Real Property Law, the approved subdivision plat shall be filed by the subdivider with the Suffolk County Clerk within 90 days of the date of signing. The approval of any plat not so filed shall expire 90 days from the date of signing by the Board, unless an extension of time is applied for in writing within said ninety-day period and thereafter granted by the Board pursuant to § 7-728 of the Village Law.
No changes, erasures, modifications or revisions shall be made in any subdivision plat after approval has been granted by the Board and endorsed on the plat. In the event that any subdivision plat, when recorded, contains any such changes, the plat shall be deemed to be null and void, and the Board shall institute proceedings to have said plat stricken from the records of the County Clerk. Any erasures made on a plat prior to its signing shall be initialed by the Clerk at the time of signing.
A. 
General procedure. The procedure for approval of a lot line modification and/or the development thereof, as defined herein, shall be the same as that for a subdivision plat, except as the Board may waive individual requirements upon application of the owner or the owner's agent.
B. 
Waiver of preliminary layout. In cases where the Board finds, after study of the sketch plan, that the proposed lot line modification is consistent with the objectives of this chapter, the Board may waive the requirement for approval of a preliminary layout and authorize the subdivider to prepare a subdivision plat for approval of the Board, upon such conditions, if any, as it may stipulate in the resolution granting such waiver and authorization.
