A. 
General.
(1) 
A preliminary plan of a subdivision must be submitted for any proposed non-residential subdivision, and may be submitted for any proposed residential subdivision. The submission of such a preliminary plan will enable the subdivider, the Board, other municipal agencies, and owners of property abutting the subdivision to discuss and clarify the problems of such subdivision before a definitive plan is prepared. Therefore, it is strongly recommended that a preliminary plan be filed in every case.
(2) 
Prior to investing in extensive professional design efforts for subdivision plans and their formal submittal, it will often prove useful to informally review the proposed development of a parcel of land with the Planning Board, in order that general approaches and potential problems can be freely explored. Simple sketches, which need not be professionally prepared, will assist the discussion and might show some but not all of the information shown on a preliminary plan. In some cases, this pre-submission review may eliminate need for a preliminary plan.
B. 
Submittals. Any person who seeks approval of a preliminary plan of a subdivision shall:
(1) 
Submit two copies of the preliminary plan to the Planning Board and one copy each to the Town Administrator, Board of Health, Conservation Commission, DPW Superintendent, Town Clerk, and Building Inspector (See Form K).[1]
[1]
Editor's Note: Form K is included at the end of these regulations.
(2) 
Submit to the Planning Board:
(a) 
An application (Form B).[2]
[2]
Editor's Note: Form B is included at the end of these regulations.
(b) 
The required administrative filing fee, plus the required review fee.
(3) 
Submit to the Board of Health:
(a) 
A copy of the application (Form B).
(4) 
Submit to the Town Clerk (by delivery or certified mail):
(a) 
A copy of the application (Form B).
(5) 
In addition to those items required to be submitted, it is requested that the following be furnished:
(a) 
A locus plan of the subdivision, showing its street configuration in relation to the surrounding area and to zoning district boundaries, at a scale of one inch equals 600 feet.
(b) 
In the case of a subdivision covering less than all of the land owned by the subdivider in the area of the subdivision, a plan showing in a general manner the proposed overall development of all said land.
(c) 
Preliminary findings, in a general way, of the environmental analysis required under § 191-8D, if expected to be required.
C. 
Plan contents. The preliminary plan shall be clearly drawn at a suitable scale preferably one inch equals 40 feet. Said preliminary plan shall show sufficient information about the subdivision to form a clear basis for its review and for the preparation of the definitive plan, and shall show:
(1) 
The subdivision name, boundaries, North point, date, scale, legend and title "Preliminary Plan."
(2) 
The name and address of record owner, applicant, registered engineer and registered surveyor.
(3)

(6) 
The approximate boundary lines of proposed lots, with approximate areas and dimensions.
(7) 
The location, names and widths of adjacent streets approaching or near the subdivision.
(8) 
The topography of the land in a general manner.
D. 
Field trip. In order to facilitate field inspection and review of the site of the proposed subdivision, it is desirable that there be temporary staking along the center line of all proposed roads in the subdivision, or if that is impractical, some alternative method of enabling on-site review.
E. 
Approval. Within 45 days after submission of a preliminary plan, the Board shall notify the applicant (by registered mail) and the Town Clerk either that the plan has been approved, or that the plan has been approved with modifications suggested by the Board or agreed upon by the person submitting the plan, or that the plan has been disapproved, and in the case of disapproval, the Board shall state in detail its reasons there for. Such approval does not constitute approval of a subdivision but does facilitate the procedure in securing final approval of the definitive plan. Prior to taking such action, the Board must be in receipt of Form K, Distribution List.[3]
[3]
Editor's Note: Form K is included at the end of these regulations.

Alternatively, the Planning Board may establish the limits of the traffic study area upon request of the applicant.
E. 
Performance guaranty.
(1) 
Form of guaranty. Before the Planning Board endorses its approval of a definitive plan, the developer shall agree to complete without cost to the Town all improvements required by this regulation, and shall provide security to do so, either by covenanting not to sell or build upon any lots until completion of the improvements (which covenant must be referred to on the plan and registered or recorded with it), or by posting bond or other security which the Town can utilize in the event that the improvements are not completed within two years, or by some combination of these. Such security shall provide, among other things, that no structure shall be occupied until streets or ways serving such structures have been surfaced with at least the binder course and berms, and any drainage facilities, utilities, streetlighting required to serve access to such structures have been installed and placed in operation.
(2) 
Security amount. If completion is secured by bond or deposit, the amount shall be determined by the Board to cover:
(a) 
The cost to the Town should it be obliged to install the required improvements.
(b) 
Maintenance for one year.
(c) 
Inflation over the time allowed for completion of work.
(d) 
Twenty-five-percent contingency.
(3) 
Release of guaranty. The Board may grant partial release from such security for partial completion of improvements, if it determines that the completed portion provides a reasonable system for circulation and utilities pending completion of the rest. The Board may release the developer from the covenant upon receipt of an agreement executed by the applicant and by the holder of a first mortgage on the premises providing for retention of funds and their availability to the Town upon default. (See MGL c. 41, § 81U, Paragraph 11.) Full security shall not be released until record plans § 191-14G have been received and until full compliance with all provisions of (§ 191-15B) is documented.
F. 
Review by Board of Health. The Board of Health shall report to the Planning Board in writing its approval or disapproval of the plan, and in the event of disapproval, shall make specific findings as to which, if any, areas shown on such plan cannot be used for building sites without injury to the public health and include specific findings and the reasons therefore in such report and, where possible, shall make recommendations for the adjustment thereto. Such Health Board or officer shall send a copy of such report, if any, to the person who submitted said plan. Any approval of the plan by the Planning Board shall then only be given on condition that no building or structure shall be built or placed upon the areas designated without written consent of the Board of Health and shall endorse on the plan such condition, specifying the lots or land to which said condition applies.
G. 
Public hearing. Before approval of the definitive plan is given, a public hearing shall be held by the Planning Board. Notice of such hearing shall be given by the Board by advertisement in a newspaper of general circulation in the Town, once in each of two successive weeks, the first publication being not less than 14 days before the day of such hearing. A copy of said notice shall be mailed to the applicant, and via certified mail to all owners of land abutting upon the subdivision as appearing in the most recent tax list.
H. 
Decision.
(1) 
After the public hearing, the Board in due course will approve, modify and approve, or disapprove the definitive subdivision plan submitted. Criteria for action by the Board shall be the following:
(a) 
Completeness and technical adequacy of all submissions.
(b) 
Determination that development at this location does not entail unwarranted hazard to safety, health and convenience of future residents of the development or of others because of possible natural disasters, traffic hazard or other environmental degradation.
(c) 
Conformity with the requirements of Article IV.
(d) 
Determination, based upon the environmental analysis (where submitted), that the subdivision as designed will not cause substantial and irreversible damage to the environment, which damage could be avoided or ameliorated through an alternative development plan.
(e) 
Access adequacy as provided at § 191-6.
(f) 
Conformity with all applicable zoning requirements.[4]
[4]
Editor's Note: See Ch. 123, Zoning.
(g) 
Consistency with the purposes of the Subdivision Control Law.
(2) 
Notice of such action, or of an agreed extension of the time for such action, must be provided by the Planning Board to the Town Clerk within 90 days following the date of submission of the plan if the plan follows action on (or failure to act on the preliminary plan within 45 days of submission) a preliminary plan, or 135 days following the date of submission in cases where no preliminary plan was submitted except where an extension of time for action is granted by the Planning Board upon request of the applicant.
I. 
Certificate of approval. The action of the Board in respect to such plan shall be by vote of a majority of the seated Board, copies of which shall be certified and filed with the applicant. If the Board modifies or disapproves such plan, it shall state in its vote the reasons for its action. Final approval, if granted, shall be endorsed on the original drawing of the definitive plan by the signatures of a majority of the Board, but not until the statutory twenty-day appeal period has elapsed following the filing of the certificate of the action of the Board with the Town Clerk, and said Clerk has notified the Board that no appeal has been filed. After the definitive plan has been approved and endorsed, the applicant shall furnish the Board with three prints thereof. Final approval of the definitive plan does not constitute the laying out or acceptance by the Town of streets within a subdivision.
J. 
Computer files. Following final action by the Board for any plan prepared using CAD software, the applicant shall submit, within 20 days of approval, computer files of the definitive plan including all information contained in the lot layout sheets, street plan and profile sheets, grading and drainage sheets, and utility sheets. The computer files shall be in AutoCAD or other common computer program format and shall comply with content, datum, coordinate system, layering, format and other requirements of the Blackstone DPW or Blackstone Graphic Information System.
A. 
Applicability. A plan which proposes no new roads, but technically constitutes a subdivision because one or more of the lots it creates lacks the frontage required by the Zoning Bylaw,[1] shall be termed a "frontage waiver plan" and shall be governed by the following, rather than by § 191-8, Definitive plan.
[1]
Editor's Note: See Ch. 123, Zoning.
