Only those plans which constitute "subdivisions," as that term is defined in § 358-2.4, require the approval of the Board. However, all plans, whether "subdivisions" within the meaning of the law or not, must be reviewed by the Board before any approval is given, or before an endorsement is made that the plan does not constitute a subdivision and therefore does not require approval. The Register of Deeds of Nantucket shall not record any plan showing a division of a tract of land into two or more lots, and ways, whether existing or proposed, providing access thereto, unless 1) such plan bears an endorsement of the Planning Board that such plan has been approved by the Planning Board, and a certificate by the Town Clerk is endorsed on the plan, or is separately recorded and referred to on said plan, that no notice of appeal was received during the 20 days next after receipt and recording of notice from the Planning Board of the approval of the plan, or, if an appeal was taken, that a final decree has been entered by the court sustaining the approval of the plan, or 2) such plan bears an endorsement of the Planning Board that approval of such plan is not required, or 3) the plan is accompanied by a certificate of the Town Clerk that it is a plan which has been approved by reason of the failure of the Planning Board to act thereon within the time prescribed, or that it is a plan submitted pursuant to MGL c. 41, § 81P and that it has been determined, by failure of the Planning Board to act thereon within the prescribed time, that approval is not required. In order to obtain a permit for the erection of a building on a lot, a way giving access to such lot must appear on a plan recorded at the Nantucket Registry of Deeds or entitled to be recorded under MGL c. 41, § 81X.
No plan for review, whether for approval or for endorsement of "approval not required," shall be accepted as a submittal unless and until all information necessary for such review, as described herein under the applicable provisions of submission requirements, are fully provided, unless waived in writing by the Board. At the time of submission, a determination shall be made by the Planning Board, or its designee, using a checklist, that the submission materials are either complete or incomplete. If the submission has been determined to be incomplete, the plan shall be returned to the applicant either in person or by certified mail with a letter indicating that insufficient information has been provided, making it impossible for the Board to adequately review the plan, to approve the plan or endorse the plan "Approval Not Required." Incomplete plans shall not be considered submittals and shall not be considered the start of any time limits within which the Board is required to act under various provisions of state law.
The following provisions apply to all plans for which "Approval Not Required" endorsement is desired.
A. 
"Approval not required" plan submission requirements. Any person may submit a plan seeking endorsement that the plan does not require approval under the Subdivision Control Law by providing the Board with the following:
(1) 
An original plan on linen or reproducible Mylar and two paper prints of the plan showing:
(a) 
The area, frontage and dimensions of the lot or lots requiring endorsement and any contiguous lots in common beneficial ownership whose dimensions are altered by the plan having area or frontage less than twice the prevailing required area and/or frontage for the zoning district in which the land is located. In a case where said contiguous lots have less than twice the required frontage but more than twice the area, only the frontage shall be shown on the plan.
(b) 
The date of the plan, scale, North point.
(c) 
The names of the record owner and the applicant, and the name, seal and signature of the registered surveyor.
(d) 
Abutting properties, with the names of owners from the most recent tax list and showing all relevant abutting lot lines.
(e) 
Zoning classification data, wetlands and floodplains.
(f) 
The Assessor's map and parcel number as it is recorded on the official Tax Maps of Nantucket and recently recorded plans for the parcel.
(g) 
The name(s) of the way(s) on which the lots front.
(h) 
The physical condition of the way(s) shown on the plan, including actual width, surface condition and available drainage.
(i) 
An area set aside for the signatures of Board members, file number and date of endorsement, preceded by the words "Approval Under the Subdivision Control Law Not Required, Nantucket Planning Board."
(j) 
A locus plan at a scale of at least one inch equals 2,000 feet, containing sufficient information so that the land can be readily located, including streets bounding on or near the property.
(k) 
Each plan shall contain a note or notes as to the compliance of each lot shown thereon with the lot area requirements as provided in Chapter 139, Zoning, § 139-2A and § 139-16A, of the Code of the Town of Nantucket. The Mylar plan shall show the entire area of such lot as computed pursuant to the minimum technical standards for surveys as set forth under 250 CMR 6.01, including such areas subject to protection under the State Wetlands Protection Act.
[1] 
The notes to be set forth on each such plan, as applicable in each individual instance, shall be substantially to the following effect:
"The Planning Board determines that:
[a] 
Lot(s) _____ is/are subject in part to protection under the Massachusetts Wetlands Protection Act, but contain sufficient lot area, as defined in the Nantucket Zoning Bylaw, to comply with the applicable zoning requirements. A Notice of Intent may be required to be filed with the Nantucket Conservation Commission with regard to proposed construction on such lot(s)."
[b] 
Lot(s) _____ does (do) not contain areas subject to protection under the Massachusetts Wetlands Protection Act which are required to be excluded from lot area under the Nantucket Zoning Bylaw, but still may be subject to protection under State and Local Wetland Bylaws. Determination of applicability may be obtained through application to the Conservation Commission."
[c] 
Lot(s) _____ contains inadequate lot area, as defined in the Nantucket Zoning Bylaw, to comply with minimum area requirements applicable under such bylaw."
[2] 
To enable the Board to make such findings, a third separate paper print shall serve as a worksheet to determine lot area compliance with zoning. This print shall show the full area of the lot, and shall also show the full area computed in accordance with Chapter 139, Zoning, of the Code of the Town of Nantucket. The boundary of each such area subject to protection under the State Wetlands Protection Act which is excluded from lot area under Chapter 139 of the Code of the Town of Nantucket shall be clearly shown and labeled upon each such plan. A note shall be included on this plan which shall be substantially to the following effect:
"Wetlands lines are approximate and for purposes of determining zoning compliance only."
[3] 
Any necessary supporting documentation shall be submitted along with the worksheet plan as part of the submission and will be kept on file with signed plans at the Planning Board office.
(2) 
A properly executed Form A application as shown in Appendix B.[1]
[1]
Editor's Note: Appendix B is included as an attachment to this chapter.
(3) 
Necessary evidence to show that the plan does not require approval, which shall include the precise legal ownership of the way(s) and proper positive documentation that every lot within the divided tract has frontage either on a public way or a way which the Town Clerk certifies is maintained and used as a public way or a way shown on a plan theretofore approved and endorsed in accordance with the Subdivision Control Law; or a way in existence on February 16, 1955, having, in the opinion of the Planning Board, sufficient width, suitable grades and adequate construction to provide for the needs of vehicular traffic in relation to the proposed use of the land abutting thereon or served thereby, and for the installation of municipal services to serve such land and the buildings erected or to be erected thereon. All plans seeking "Approval Not Required" endorsement shall be accompanied by adequate evidence that there is practical interior access to the proposed house sites. Plans and profiles of access roads previously approved by the Planning Board which do not provide frontage for any lot shown on a subject plan shall not be construed as a way shown on a plan theretofore approved and endorsed in accordance with the Subdivision Control Law.
B. 
"Approval not required" plan filing procedures.
(1) 
Persons seeking endorsement of plans "Approval Not Required" shall submit such plans, either by mail or in person, to the Nantucket Planning Board, the Town and County Building, 16 Broad Street, Nantucket, Massachusetts 02554. In order to be included in the agenda for consideration at a Planning Board meeting, the plan must be submitted to the Planning Board office before 12:00 noon of the Wednesday before the meeting. Any plans received after the Wednesday 12:00 noon deadline will automatically be carried over to the agenda for the following meeting, unless the Chair, with staff recommendation, determines there are special circumstances that warrant a late submittal.
(2) 
A fee shall accompany the application in an amount set from time to time by the Planning Board.
(3) 
The applicant shall file, by delivery or registered mail, a notice with the Town Clerk stating the date of submission for such determination.
C. 
"Approval not required" plan action.
(1) 
A determination of wetland boundaries from the Nantucket Conservation Commission may be required in order to verify that the area of one or more lots complies with zoning requirements. For plans which are submitted without such determination, and for which a question as to the accuracy of the delineation of wetland boundaries arises, the applicant shall obtain a determination from the Conservation Commission. Failure to do so within the twenty-one-day statutory decision period shall cause the Planning Board to add a notation to the plan stating that the lot in question has not been determined to have sufficient area to comply with zoning requirements and to notify the Building Department that a building permit shall not be issued until the Planning Board has been provided satisfactory information to determine that the lot in question has sufficient area to meet lot area requirements.
(2) 
If the Board determines that the plan does not require approval, it shall forthwith, without public hearing, endorse the plan accordingly. The plan shall be returned to the applicant so endorsed within 14 days of submission of said plan.
(3) 
If the Board determines that the plan does require approval, it shall, without a public hearing and within 21 days of submission, notify the applicant and the Town Clerk of the determination.
(4) 
If the Board fails to take action within 21 days of submission, the plan is automatically deemed not a subdivision plan and the Board shall forthwith make such endorsement. On its failure to do so forthwith, the Town Clerk shall issue a certificate to the same effect.
D. 
Ways in existence. Existing ways will normally be determined by the Board to provide adequate access to qualify a plan as not constituting a subdivision only when the layout, design and construction meet the standards of these rules and regulations.
Prior to investing in extensive professional design efforts for subdivision plans, it will often prove useful to review the proposed development of a parcel of land with the Board in an informal manner, in order that general approaches, possible use of cluster development, and potential problems can be freely explored. Pencil sketches and other illustrations, 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, presubmission review may eliminate the advisability of submitting a preliminary plan. However, the presubmission review provision is strictly a voluntary procedure left to the discretion of the applicant. The presubmission review has no legal status whatsoever, insofar as zoning exemptions are concerned.
A preliminary plan of a residential subdivision may, and a preliminary plan of a nonresidential subdivision shall, be submitted by the subdivider for discussion and approval, modification or disapproval by the Planning Board and the Board of Health. The submission of such a preliminary plan will enable the subdivider, the Planning Board, and other municipal agencies to discuss and clarify the problems of such a subdivision before extensive engineering costs are incurred in the preparation of the definitive plan.
A. 
Submission requirements. Preliminary plans shall be drawn on tracing paper, or a print thereof, and shall show:
(1) 
The subdivision name, boundaries, North point, date, scale, legend and title "Preliminary Plan";
(2) 
The names of the record owner and the applicant and the names of the designer, engineer and surveyor;
(3) 
The names of all abutters, as determined from the most recent tax list;
(4) 
The existing and proposed line of streets, ways, easements, any public or common areas and lots shown in a general manner;
(5) 
A schematic representation of the proposed system of drainage, including adjacent existing natural waterways;
(6) 
The approximate boundary lines of proposed lots, with approximate areas and dimensions;
(7) 
The names, approximate location and widths of adjacent streets;
(8) 
The topography of the land in a general manner, including areas of the tract suspected to be floodprone and/or wetlands;
(9) 
A vicinity map to appear in the upper right corner of the plan showing the location of the parcel as it relates to areas of the community within at least one-half mile of the tract boundaries (suggested scale: one inch equals 2,000 feet);
(10) 
The zoning classification of the land to be subdivided;
(11) 
Proposed sewage, water and utility systems, shown in a general manner; and
(12) 
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 of said land.
B. 
Filing procedures for preliminary plans.
(1) 
An application for consideration of the preliminary plan shall be accompanied by 12 contact prints of the plan and a filing fee as set from time to time by the Planning Board. The applicant shall also file one contact print with the Board of Health.
(2) 
The applicant shall give written notice to the Town Clerk of Nantucket by delivery or by registered mail, postage prepaid, that the applicant has submitted such a plan.
C. 
Plan action for preliminary plans. Within 45 days after submission of a preliminary plan, the Board shall either approve the plan, with or without modifications, or the Board shall disapprove the plan. In the case of disapproval, the Board shall state its reasons therefor. The Board shall notify the Town Clerk of its action in writing. The action of the Board shall be on two copies of the preliminary plan, referenced and attached to any conditions. One copy shall be returned to the applicant and the other retained by the Board. Approval of the preliminary plan does not constitute approval of the subdivision for recording but does facilitate the procedure in securing approval of the definitive plan. The Rules and Regulations Governing the Subdivision of Land in effect at the time of its submission shall govern the definitive plan evolved from such preliminary plan, provided that the definitive plan is duly submitted within seven months from the date of submission of the preliminary plan and said definitive plan is ultimately approved. Such exemptions shall endure for eight years from the date of definitive plan approval.
The definitive plan of a subdivision shall conform substantially to the preliminary plan as approved but may constitute only that portion which is proposed to be recorded and developed at the time. The subdivision rules and regulations and zoning in effect at the time of the submission of the preliminary plan shall govern the definitive plan if it is duly submitted within seven months. Applicants are strongly urged to schedule a presubmission conference and tour with the Planning Board and its staff to identify as early as possible any items requiring special attention.
A. 
Submission requirements. An applicant seeking approval of a definitive plan of a subdivision shall file with the Board the following:
(1) 
The original drawings of the definitive plan and 12 prints thereof, which shall be distributed for review to the following agencies: Conservation Commission, Department of Public Works, Fire Department and Water Company.
(2) 
A street network plan shall be submitted on 8.5-inch-by-11-inch paper showing, at a minimum, proposed, existing, and adjacent streets, names and locations of abutters, North arrow, and any adjacent natural features.

"Abutters" shall be defined as those landowners immediately bordering the proposed subdivision, those landowners abutting the immediate abutters, and those landowners located directly across all segments of streets and ways bordering the proposed subdivision.
(5) 
A master plan showing a possible or prospective street and lot layout for any adjacent unsubdivided land owned or controlled by the owner or subdivider of the subdivision shall be submitted, unless such a plan has already been filed with the Board.
(6) 
A filing fee shall accompany the application in an amount set from time to time by the Planning Board.
(7) 
In addition to the filing fee, applications shall be accompanied by a check in an amount set from time to time by the Planning Board per linear foot of new or reconstructed interior or perimeter roadway in accordance with Subsection K located herein, to be deposited into a Road Inspection Escrow Account within the Town Treasury, to be kept separate from other funds, the proceeds of which shall be drawn upon from time to time by the Board to pay for costs associated with the inspection of the applicant's required public improvements.
(8) 
A proposed covenant or bond in accordance with Subsection F, Performance Guarantee.
(9) 
Notice to Town Clerk. The applicant shall give written notice to the Town Clerk by delivery or by registered mail, postage prepaid, that the applicant has submitted such a definitive plan, accompanied by a copy of the application, within 48 hours of submission. If the notice is given by delivery, the Town Clerk shall, if requested, give a written receipt therefor to the person who delivered such notice. Such notice shall describe the land to which the plan relates sufficiently for identification, and shall state the date when such plan was submitted and the name and address of the owner of such land; and the facts stated in such notice shall be taken by the Town Clerk as true, unless contrary is made to appear. If sent by registered mail, the date of the mailing shall be the date of submission of the definitive plan. The definitive plan shall be considered submitted only when all plan requirements specified in Subsections A and B of this section are included, unless waived in writing by the Board, as provided in § 358-2.5.
(10) 
The Planning Board shall require the submission of storm drainage runoff flow calculations in order to evaluate the drainage plan.
(11) 
Site analysis report and map.
(a) 
An applicant seeking approval of a definitive plan shall submit, at the time of filing, three copies of a Site Analysis Report and three copies of a Site Analysis Map. Any submission of a definitive plan lacking these documents will be considered incomplete (§ 358-2.8).
(b) 
The Site Analysis Map shall be one sheet of drawing paper no larger than 42 inches by 60 inches and shall show the entire subdivision at a suitable scale. If the definitive plan includes less than the preliminary plan from which it was derived, the Site Analysis Map shall include all the land shown on the preliminary plan. Applicants are encouraged to use tissue, acetate or Mylar overlays in conjunction with a paper base map. The base for the Site Analysis Map shall show tract boundaries, proposed lots, ways, easements, open spaces, landmarks and existing structures and roads within 100 feet of the tract boundaries. Overlays using color or black-and-white patterns shall show the following information:
[1] 
Wetlands, including ponds, marshes, bogs, streams and all areas of the site subject to the Massachusetts Coastal Wetlands Act, as amended;
[2] 
Areas of special flood hazard, as designated by the Federal Emergency Management Agency (FEMA) as part of the Flood Insurance Program for Nantucket;
[3]

[6] 
Predominant vegetative cover type, including areas of the site the applicant feels are important to protect and all areas containing stands of trees with three-inch caliper or more; and
[7] 
Protected areas, including all areas of the tract permanently kept from being developed by virtue of their being scenic, access, drainage or slope easements, or through other interest of fee-simple grants of land to a conservation group or homeowners' association.
(c) 
The Site Analysis Report shall be a typed copy on 8.5-inch-by-11-inch paper with a cover sheet indicating the name of the subdivision, the owner of the land, the applicant, the engineer/surveyor/land planner and the date of submission. The report shall consist of a narrative statement and appropriate data, documenting the likely impact of the subdivision on the following subject areas with references to the Site Analysis Map:
[1] 
Surface water resources. How will the proposed subdivision, when fully developed, affect the quality and quantity of ponds, marshes, bogs, streams and other surface water resources both on and off the site? What measures have been taken to assure full compliance with the State Coastal Wetlands Act? Will drainage easements be used to identify and protect portions of individual lots subject to the State Coastal Wetlands Act in order that prospective purchasers of lots in the subdivision will be adequately aware of the status of their property? What erosion and sediment control measures will be taken to prevent undue loss of topsoil and sedimentation of surface waters during construction? Has public access been provided to significant surface water resources?
[2] 
Groundwater resources. How will the proposed subdivision, when fully developed, affect the quality and quantity of groundwater resources in the area? Has every effort been made to tie in with the community-wide sewage system? Have percolation tests been done on every lot to be used for residential or commercial purposes in the subdivision?
[3] 
Flood hazard. Has the layout of streets and lots fully reflected the need to protect life and property by properly locating building lots out of areas of special flood hazard as delineated by the federal government? Will floodway easements be used to protect these areas from encroachment and advise lot purchasers of the nature of their prospective property? Has the proposed system of drainage taken severe storm damage into account?
[4] 
Vegetative cover. Are there any groves of trees with three-inch caliper or more? If so, what measures have been taken to protect them? Has the applicant considered cooperating with the Nantucket Conservation District in reforesting portions of the tract at minimal cost? Have scenic or access easements or fee-simple grants of land been employed to protect valuable areas of the site?
[5] 
Traffic safety and convenience. Does the subdivision provide for adequate internal circulation for both pedestrian and vehicular/bicycle traffic? Is the site served adequately by existing roads in the area when other subdivisions (both built-up and unbuilt) are considered? Has the applicant considered tying in with Nantucket's Island-wide bicycle path system? Has there been sufficient consideration for tying into anticipated future subdivisions on adjacent tracts of land now vacant? Will emergency vehicles be able to properly service this new neighborhood? What form of performance guarantee will be used for all public improvements? What is the physical condition of adjacent roads and access roads (width, surface and drainage)? What is the precise legal ownership of adjacent roads and access roads? Will the subdivision substantially affect traffic flow and safety in the area surrounding the subdivision? If so, what mitigating measures are being undertaken to decrease any detrimental effects?
[6] 
Development phasing. When will all the required public improvements be completed? If this is the first of several definitive plans based on a larger preliminary plan, when does the applicant expect to submit other definitive plans? What will be the maximum number of dwelling units on this definitive plan (including seasonal cottages)?
[7] 
Common open spaces. If the applicant includes in the plan common open spaces and other neighborhood facilities and services, how will such areas be owned and maintained (homeowners' association, trust, condominium association, etc.)? Are these areas permanently preserved?
(d) 
If any questions arise during the public hearing concerning the aforementioned subject areas, the Planning Board may require complete and detailed substantiation of any claim by the applicant, which could include an investigation by an outside consultant.
(12) 
Traffic study.
(a) 
If, in the opinion of the Planning Board, the size, scale or location of the subdivision may result in a significant impact on the surrounding road system, the Board may require the applicant to submit a traffic study. The study shall be prepared by a professional engineer specializing in traffic analysis and identify, at a minimum, the following:
[1] 
Internal vehicular circulation patterns.
[2] 
Estimated daily and peak-hour vehicle trips.
[3] 
The measured daily and peak-hour traffic flows, both weekday and weekend (nonholiday), measured during the period between June 15 and September 15, or other times as the Board may deem appropriate, on public and private roads and key intersections expected to be impacted by the project.
[4] 
Proposed composite daily and peak-hour traffic on public and private roads and key intersections; a documentation of impacts on level of service.
[5] 
Suggested remedial measures to mitigate the expected impacts of the proposed subdivision.
(b) 
Applicants are urged to meet with the Planning Board or planning staff prior to preparation of the study to identify the study area and the appropriate elements of the traffic study.
B. 
Contents of the definitive plan. A definitive plan of a subdivision shall be drawn on linen or reproducible Mylar by a registered land surveyor at a scale of one inch equals 40 feet, or such other scale as the Board may accept to show details clearly and adequately, but no smaller than one inch equals 100 feet. Sheet sizes shall not exceed 24 inches by 36 inches. If multiple sheets are used, they shall be accompanied by an index sheet showing the entire subdivision. The definitive plan shall show the following:

The notes to be set forth on each such plan, as applicable in each individual instance, shall be substantially to the following effect:
"The Planning Board determines that:
[1] 
Lot(s) __________ is/are subject in part to protection under the Massachusetts Wetlands Protection Act, but contain sufficient lot area, as defined in the Nantucket Zoning Bylaw, to comply with applicable zoning requirements. A Notice of Intent may be required to be filed with the Nantucket Conservation Commission with regard to proposed construction of such lot(s)."
[2] 
Lot(s)_____ does/do not contain areas subject to protection under the Massachusetts Wetlands Protection Act which are required to be excluded from lot area under the Nantucket Zoning Bylaw but still may be subject to protection under State and Local Wetland Bylaw. Determination of applicability may be obtained through application to the Conservation Commission."
[3] 
Lot(s) __________ contains inadequate lot area, as defined in the Nantucket Zoning Bylaw, to comply with minimum area requirements applicable under such bylaw."
(b) 
To enable the Board to make such findings, a third, separate paper print shall serve as a worksheet to determine lot area compliance with zoning. This print shall show the full area of the lot, and shall also show the area of lot as computed in accordance with Chapter 139, Zoning, of the Code of the Town of Nantucket. The boundary of each such area subject to protection under the State Wetlands Protection Act which is excluded from lot area under Chapter 139, Zoning, shall be clearly shown and labeled upon each such plan. A note shall be included on this plan which shall be substantially to the following effect:
"Wetlands lines are approximate and for purposes of determining zoning compliance only."

(2) 
The Board of Health shall, within 45 days after filing of the plan, report to the Planning Board, in writing, with its recommendation of approval or disapproval of said plan. If the Board of Health disapproves said plan, it shall make specific findings as to which, if any, of the lots shown on such plan cannot be used for building sites without injury to the public's health.
(3) 
Every building lot so located that it cannot be served by a connection to the municipal sewer system shall be provided with a sewage disposal system approved by the Board of Health.
D. 
Review by other officials.

F. 
Performance guarantee.
(1) 
Before endorsement of its approval of a definitive plan, the Planning Board shall require that the construction of ways and the installation of municipal services be secured by one of the four methods listed below, or a combination of methods which, from time to time, may be varied by the applicant upon approval of the Board:
(a) 
By a proper bond, sufficient in the opinion of the Planning Board to secure performance of the construction of ways and the installation of municipal services required for lots in the subdivision shown on the plan; and the Planning Board may require that the applicant specify the time within which such construction shall be completed.
(b) 
By a deposit of money or negotiable securities sufficient in the opinion of the Planning Board to secure performance of the construction of ways and the installation of municipal services required for lots in the subdivision shown on the plan; and the Planning Board may require that the applicant specify the time within which such construction shall be completed.
(c) 
By a covenant, executed and duly recorded by the owner of record, running with the land, whereby such ways and services shall be provided to serve any lot before such lot may be built upon or conveyed, other than by mortgage deed; provided that a mortgagee who acquired title to the mortgaged premises by foreclosure or otherwise and any succeeding owner of such premises or part thereof may sell any such lot, subject to that portion of the covenant which provided that no lot shall be built upon until such ways and services have been provided to serve each lot; and provided, further, that nothing herein shall be deemed to prohibit a conveyance by a single deed, subject to such covenant, of either the entire parcel of land shown on the subdivision plan or of all lots not previously released by the Planning Board. A deed of any part of the subdivision in violation hereof shall be voidable by the grantee prior to the release of the covenant but not later than three years from the date of such deed. A suggested, but not required, form of the covenant is given by Form I in Appendix B,[2] which form may be changed from time to time by the Planning Board. Any covenant given under the preceding paragraph and any condition required by the Board of Health shall be either inscribed on the plan or contained in a separate document, referred to on the plan.

(d) 
By delivery to the Planning Board of an agreement executed after the recording of a first mortgage covering the premises shown on the plan or a portion thereof given as security for advances to be made to the applicant by the lender, which agreement shall be executed by the applicant and the lender and shall provide for the retention by the lender of funds sufficient in the opinion of the Planning Board and otherwise due the applicant to secure the construction of ways and the installation of municipal services. Said agreement shall also provide for a schedule of disbursements which may be made to the applicant upon completion of various stages of the work, and shall further provide that in the event the work is not completed within the time set forth by the applicant, any funds remaining undisbursed shall be available for completion.
(2) 
The penal sum of any such performance guarantee described under Subsection F(1)(a), (b) or (d) shall bear a direct and reasonable relationship to the expected cost, including the effects of inflation, necessary to complete the subject work. Such amount or amounts shall from time to time be reduced so that the amount bonded, deposited or retained continues to reflect the actual expected cost of work remaining to be completed.
(3) 
The form of the performance guarantee may be as given by Form G or Form I in Appendix B,[3] or as otherwise required by the Board, and shall be contingent upon the completion of said improvements within two years of the date of the agreement. At the discretion of the Board, a time extension may be granted for a period not to exceed one year, provided such an extension may be conditioned upon an increase in the amount of such bond or security as determined by the Board.
[3]
Editor's Note: Appendix B is included as an attachment to this chapter.
(4) 
The failure of the applicant to complete the required construction of ways and installation of municipal services within two years from the date of the agreement shall be grounds for the rescission of the approval of the plan.
G. 
Public hearing. Before approval, modification and approval or disapproval of the definitive plan, a public hearing shall be held by the Board after proper advertisements and notification of abutters as provided by MGL c. 41, § 81T of the Subdivision Control Law.
H. 
Plan action.
(1) 
After the public hearing, the Board shall approve or, if such plan does not comply with the Subdivision Control Law, these rules and regulations or recommendations of the Board of Health, shall modify and approve, or disapprove the definitive plan.

(2) 
In the case of a nonresidential subdivision where a preliminary plan has been duly submitted and acted upon or where 45 days have elapsed since submission of the preliminary plan, and then a definitive plan is submitted, the failure of the Planning Board either to take final action or to file with the Town Clerk a certificate of such action regarding the definitive plan submitted by an applicant within 90 days after such submission, or such further time as may be agreed upon at the written request of the applicant, shall be deemed to be an approval thereof. Notice of such extension of time shall be filed forthwith by the Planning Board with the Town Clerk.
(3) 
In the case of a subdivision showing lots in a residential zone, where a preliminary plan has been acted upon by the Planning Board or where at least 45 days have elapsed since submission of the preliminary plan, and a definitive plan is submitted, the failure of the Planning Board to take final action or to file with the Town Clerk a certificate of such action on the definitive plan within 90 days after such submission, or such further time as may be agreed upon at the written request of the applicant, shall be deemed to be an approval thereof. Notice of such extension shall be filed forthwith by the Planning Board with the Town Clerk.
(4)

The applicant shall have submitted to the Board a set of plans appropriately prepared for said endorsement and shall have included with these plans a road layout plan reduced to fit 8.5-inch-by-11-inch paper. In case of the approval of such plan by reason of the failure of the Board to act within the time prescribed, the Town Clerk shall, after the expiration of 20 days without notice of appeal to the Supreme Court or Land Court, or, if appeal has been taken, after receipt of certified records of the Supreme Court or Land Court indicating that such approval has become final, issue a certificate stating the date of the submission of the plan for approval, the fact that the Board failed to take action and that the approval resulting from such failure has become final.

(a) 
Prior to the endorsement of a plan as approved, and prior to the return of such plan to the applicant, the applicant shall be required to deposit with the Treasurer of the Town an amount set from time to time by the Planning Board times the number of linear feet of proposed or reconstructed ways located within and outside of the boundaries of the subdivision. The Planning Board shall direct the Treasurer to expend such funds to pay for all reasonable design review, construction inspection services and subdivision modification design reviews by its engineer or other professional persons required to assist the Planning Board in its determination as to the adequacy of the definitive plan with regard to the Subdivision Control Law and these rules and regulations and as to the adequacy of the subdivision construction and any design modifications to the plan and changes made in the field.
(b) 
However, no such payment shall be directed until 14 days after a photocopy of the bill purporting to represent charges for such services and review has been sent, by certified mail, to the applicant. The balance of this account shall at no time be less than 1/2 the initial deposit, and the applicant shall deposit with the Treasurer such additional funds as are required to restore the account to the amount of the initial deposit upon notice from the Board, by first class mail, that the amount on deposit has been decreased by the expenditures described herein to an amount at or near 1/2 the initial deposit. The account shall be closed and the remaining funds returned to the applicant when, in the opinion of the Board, all work required by the approved plan, any conditions placed upon such approval, and any subsequently approved modifications and these rules, and all inspections required by these rules, have been completed.
(c) 
The failure of the applicant to make the initial deposit, and to maintain the account in accordance with this subsection, shall be grounds for rescission of the approval of the plan and for disapproval.
(d) 
The full cost of any special nonscheduled inspections deemed necessary by the failure of construction to proceed entirely in accordance with the approved plan, or as a result of any question concerning the accuracy of any data provided by the applicant at any time, shall be borne by the applicant.
(e) 
In the event the Planning Board denies approval of a plan, the account shall be closed and the unexpended funds returned to the applicant within 21 days from the date the subdivision plan was denied an approval.
(f) 
The Planning Board, in its discretion, may waive or refund the inspection fee in whole or in part to the extent the Board determines that professional or other services were not required in consideration of the definitive plan.

Nine elevation points shall be shown across the right-of-way, including center line of road, five feet off center line in both directions, both edges of surface, edge of right-of-way, top of slope or toe of slope and edge of shoulders. Two-inch or greater core samples shall be taken and reported along with each cross-section to determine thickness of paving material, said samples to be determined by the Planning Board.
(3) 
"As built" plans, profiles and cross-sections shall be prepared by, bear the stamp of, and be signed by a Registered land surveyor or registered engineer, and shall include the following statement: "I hereby certify that the plans, profiles and cross-sections included herein were prepared as the result of survey work performed on the ground and represent conditions in the field as they existed on __________ (date)."

[2] 
Annual maintenance deposits shall consist of interest generated by the endowment and annual assessments made to association members, the amount of such annual assessment to be established by majority vote of the association.
