All of the information included in this section shall be included in the Definitive Plan set. The Board may additionally required additional information to be shown on the plan, including any information related to conditions of approval or necessary for the determination of compliance with these Regulations.
A. General Information.

(f) Any revision dates and a brief description of the revision;
(g) Engineer and surveyor stamp, signature, name, and address;
(i) Page number (if applicable).
(3) Locus Map. The locus map shall show the limits of the subdivision, the location of the proposed ways, and shall generally follow the orientation of the plan. The scale of the locus map shall be 1" = 2,083' (1:25,000).
(4) Additional Identifying Information.
(a) Names and address of record owner and applicant, the book and page number of the recording of the deed.
(b) Names of all abutters as determined from the most recent local tax list unless the applicant shall have more recent knowledge of such abutters, including owners of land separated from the subdivision only by a street; and zoning district boundaries, if any.
(c) House numbers of each house abutting the property sidewalk, lots, rights-of-way, easements, and any public or common areas within the subdivision. (The proposed names of proposed streets shall be shown in pencil until they have been approved by the Board). Purpose of easement shall be indicated.
(d) Location, names, and present widths of streets bounding, approaching, or within immediate proximity of the subdivision, showing both the roadway widths and right-of-way widths.
(e) Suitable space to record the action of the Board and the signatures of the members of the Board on each sheet of the Definitive Plan. Where the applicant elects to secure completion of required improvements by covenant (rather than bonds or surety), there shall be a notation above such space as follows:
Approved__________, subject to a covenant conditions set forth in a covenant executed by____________________ dated__________, and to be (recorded-registered) herewith.
B. Physical Features & Topography.
(1) Location of natural waterways and water bodies within and existing adjacent to the subdivision.
(2) Major existing site features, such as stone walls, fences, buildings, trees 10" or larger within 50' on each side of the proposed center line of roadways or rights-of-way, rock ridges and outcroppings, identifiable historical sites, and swamps. Special attention should be given to noting physical features which define the boundaries of the subdivision.
(3) Existing and proposed topography, with two-foot contour intervals, unless a smaller contour interval is required to properly define the existing or proposed topography. The surface and bottom elevation of all water bodies within the subdivision shall be given and ground surfaces identified as to type, such as woodland, swamp, ledge outcrops, wetland and flood plain as defined under the zoning regulations. The location of all watercourses exiting the subdivision shall be tied into the nearest perimeter monument.
(a) In the event that there are no wetlands and/or flood plains on any land within 100 feet of the perimeter of the subdivision a statement to this effect shall be so noted on the plans as applicable.
(4) All work done outside the limits of the proposed subdivision shall be shown on a separate sheet.
(5) In any subdivision of land where earth removal will be done the applicant must show all areas of clearing and earth removal necessary for construction, roadways, easements, drainage basins, etc.
(6) A chart indicating lots within the wetlands or flood plain areas of the subdivision shall be provided on the first sheet or cover sheet of the definitive plan.
C. Layout of Lots and Roadway.
(1) Sufficient data including lengths, bearings, radii, and central angles to determine the exact location, direction, and length of every street and way line, lot line, boundary line, and easement, and to establish these lines on the ground.
(2) Location of all existing and proposed permanent monuments and benchmarks, identified as to whether existing or proposed (see monument requirements in §
501-23H).
(a) All benchmarks shall refer to the NGVD datum system.
(b) Permanent benchmarks shall be on a recordable survey plan in conformance with the procedural and technical standards of the practice of land surveying, and shall show the subdivided property tied into the Massachusetts State Plane Coordinates (1983) system.
(c) Distances between proposed monuments shall be shown on the plan.
(3) Existing and proposed boundary lines, parcel areas in square feet, and dimensions of all proposed lots, with all lots designated numerically and in sequence.
(4) The exterior lines of existing streets entering the subdivision and existing utility lines and appurtenances or easements shall be shown on the plan to clearly indicate location of proposed connections.
(5) Traffic sight distances, vertical and horizontal, for all intersections within the subdivision and for the public ways adjoining the subdivision at location of ingress or egress shall be shown.
D. Utilities & Construction Details.
(1) Standard utility construction details shall be shown on the plan.
(2) Where any utilities or stormwater management devices are proposed outside of the roadway layout, they shall be clearly marked on the plan as a separate sheet. The purpose of this will be to provide future homeowners a clear understanding of the location and purpose of any utilities for which they may be responsible.
(3) Profiles on the lines of proposed streets and 100 feet beyond at a horizontal scale of 1" = 40' and a vertical scale of 1" = 4', or such other scales acceptable to the Board. All elevations shall refer to NGVD datum. Profiles shall also indicate the location of any intersecting public or private ways, and the location, material and size of existing and proposed storm drains, water mains, and sewers and their appurtenances, fire alarm, street lighting, and other underground utilities to be placed in the right-of-way.
(a) On the same sheet, there shall be drawn typical cross sections of the proposed street, properly located and identified by station number, at such intervals along the streets as will adequately indicate any variations in its section, supplemented, where necessary, by lines on the layout plan showing the width and location of proposed roadways, planting strip, gutters, sidewalks, and similar physical features.
(4) Any special construction details or other pertinent information which the Board may request as being necessary to evaluate the feasibility of the proposed design of the subdivision.
(5) Detail drawings. Any special construction features, deviating from or not covered by Standard Specifications shall be shown on detail drawings. Such detail drawings may be incorporated as part of a utility plan or profile or may be executed on a separate sheet or sheets and shall provide information as to dimensions, location, elevations, cross sections, materials, etc., of the construction details involved. The requirement for detail drawings shall be applicable, but not limited to, bridges, culverts, structurally stabilized slopes, utility piping encased in concrete, ditches and brooks shaped or constructed to a definite cross section, dams and spillways, steps within the exterior lines of the street and similar construction features indicating surface water flows to the subdivision, within the subdivision, and impact after exiting the subdivision. The plan shall cross-reference the drainage calculations included in the Stormwater Report.
E. Landscaping.
(1) Any proposed landscaping, required or otherwise. Required trees (see §
501-31 for tree planning requirements) shall be clearly marked and numbered, and should be shown in color.
(2) Where a vegetated buffer is required, the landscaping plan shall include a detailed planting plan. Where the vegetated buffer is proposed to be provided by natural, existing vegetation, an approximate mix and location of existing species shall be shown on the plan sufficient to demonstrate to the Board that the existing vegetation is sufficiently dense.
(3) Where any rain gardens or other bioengineered stormwater management techniques are proposed, detailed landscaping plans shall be included in the Definitive Plan set.
F. Community or Common Facilities.
(2) Common mail box (if applicable)
(3) Dumpsters or garbage areas (if applicable)
