A. 
The preliminary plat and supporting material for a proposed subdivision constitute the material to be officially submitted to the Planning Board. They show the general design of the subdivision and its public improvements to the extent necessary for the Planning Board to indicate to the subdivider whether the proposal is acceptable as a basis for detailed design of the final plat. The preliminary plat shall require a public hearing.
B. 
Approval of the preliminary plat does not constitute an approval of the final plat, nor is it a valid basis for the construction of site improvements or other commitments which depend upon its design characteristics.
C. 
The preliminary plat shall serve as a key map to final plats subsequently laid out in sections and shall include all contiguous properties of the developer.
D. 
If a revision of the proposed subdivision is found necessary, the preliminary plats shall be revised accordingly to keep the files of the Planning Board current.
A. 
The submission of a preliminary plat shall consist of the following items:
[Amended 3-8-1996 by L.L. No. 4-1996; 12-13-2002 by L.L. No. 16-2002]
(1) 
Application for preliminary plat approval.
(2) 
The preliminary plat in sufficient quantity to allow the Planning Board to make all applicable referrals. (Check with the office of the Planning Board.)
(3) 
Preliminary drainage designs and street profiles (three copies).

Time and place of submission.
[Amended 3-26-2004 by L.L. No. 6-2004]
(1) 
The subdivider shall file his complete submission for the preliminary plat, including the application fees and engineering review fees, at the office of the Planning Board. A proposed submission which does not include all of the required drawings and documents will not be accepted by the Planning Board. A submission shall be filed at least 15 days prior to a meeting date to be heard at that particular meeting, and a public hearing shall be held on the preliminary plat within 62 days after the receipt of a complete preliminary plat by the Clerk of the Planning Board. If such Board determines that an environmental impact statement is required, and a public hearing on the draft environmental impact statement is held, the public hearing on the preliminary plat and the draft environmental impact statement shall be held jointly no less than 15 days and no more than 60 days after the filing of the notice of completion of such draft environmental impact statement in accordance with the provisions of the state regulations for the Environmental Quality Review Act. If no public hearing is held on a draft environmental impact statement, the public hearing on the preliminary plat shall be held within 62 days of the filing of the notice of completion.
C. 
The office of the Planning Board shall deliver one copy of the preliminary plat to the Town Engineer and/or Superintendent of Highways, and he shall report his evaluation of the tentative drainage plan and street profiles to the Planning Board.

Editor's Note: Former § 111-13, Application fees, as amended 3-8-1996 by L.L. No. 4-1996, was repealed 12-13-2002 by L.L. No. 16-2002.
A. 
Approval of a preliminary plat may be revoked by the Planning Board unless a proper application for approval of the final plat has been submitted to the Planning Board within six months of the approval of the preliminary plat.
B. 
No Planning Board action will be taken after such revocation until a new application, filing fee and engineering review fee, if required, are submitted. The Planning Board may grant a six-month extension of preliminary plat approval upon written request by the subdivider, who shall present adequate reasons for the delay of the final plat submission.
