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. The preliminary plat shall be clearly marked "preliminary plat."
[Amended 9-17-1993 by L.L. No. 8-1993]
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.
A. 
The submission of a preliminary plat shall consist of the following items:
(1) 
Application for preliminary plat approval.

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).
(4) 
Subdivision application fee.
(5) 
Review fee when required by this chapter.
[Amended 9-17-1993 by L.L. No. 8-1993; 6-4-1997 by L.L. No. 1-1997]

Editor's Note: See Environmental Conservation Law Article 8.
B. 
The subdivider shall file the required items for the preliminary plat submission at the office of the Planning Board. A proposed submission which does not include all the required items will not be accepted by the Planning Board. A submission shall be filed 15 days prior to a meeting date to be reviewed at that particular meeting.
[Amended 9-17-1993 by L.L. No. 8-1993]
C. 
The office of the Planning Board shall deliver one copy of the preliminary plat to the Village Engineer, and he shall report his evaluation of the tentative drainage plan and street profiles to the Planning Board.
D. 
If the proposed subdivision requires referral to the Suffolk County Planning Commission, the office of the Planning Board shall refer the preliminary plat to such Planning Commission.
[Added 9-17-1993 by L.L. No. 8-1993]
E. 
No preliminary plat submission shall be deemed complete until either a negative declaration has been made pursuant to SEQRA and its implementing regulations or, if a positive declaration has been made, until a draft environmental impact statement has been filed and accepted as satisfactory with respect to its scope, content and adequacy for the purpose of commencing public review.
[Added 9-17-1993 by L.L. No. 8-1993]
F. 
The Planning Board shall hold a public hearing on the preliminary plat within 62 days after the receipt of a complete preliminary plat submission. The office of the Planning Board shall advertise such public hearing at least five days prior to the hearing date, as required by law.
[Added 9-17-1993 by L.L. No. 8-1993]
G. 
The Planning Board shall approve, disapprove or approve with modifications the preliminary plat within 62 days after the public hearing, unless such time period is extended by mutual consent of the subdivider and the Planning Board or unless such time period is otherwise extended by applicable law.

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 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.
