A. 
Where a proposed park, playground, school or other public use shown in the Master Plan is located in whole or in part in a subdivision, the Planning Board may require the dedication or reservation of such area within subdivision in those cases in which the Board deems such requirements to be reasonable.
B. 
Where deemed essential by the Planning Board, upon consideration of the particular type of the development proposed in the subdivision, and especially in large-scale neighborhood unit developments not anticipated in the Master Plan, the Board may require the dedication and reservation of such other area or sites of a character extent and location suitable to the needs created by such development for schools, parks, water plants, sewer treatment plants and other community purposes.
C. 
As a condition of final approval of the subdivision plat, the developer shall set aside 10% of the site for the provision of park and/or recreational facilities. If provision of such facilities, within the judgment of the Planning Board, is impractical because of the particular layout of the development or for other reasons, a recreation fee of $300 per subdivision lot shall be submitted prior to final approval of the subdivision plat, unless such other terms and conditions regarding payment of said fee are entered into between the developer and the Planning Board.
The Planning Board may require the planting of trees, specifying the kind, size and location of such trees, or the Board may require the removal of existing trees or shrubbery.
[Amended 1-7-2004 by L.L. No. 2-2004]
The applicant's engineer shall prepare the design plans and special specifications, if required, for all public improvements required for the final development of the subdivision. Design plans for all public improvements and infrastructure are subject to the review of the Town Engineer and review and approval of the Highway Superintendent and shall be designed in accordance with all applicable provisions of this Code, including Chapter A127, Street and Highway Specifications, and cited references.
The Planning Board shall, wherever possible, establish the preservation of all natural features which add value to residential and commercial developments and the community, such as large trees or growths, watercourses and falls, historic spots, vistas and similar irreplaceable assets.
A. 
Conformity to the Master Plan and Official Map. The arrangement, character, extent, width, grade and location of all streets shall conform to the Master Plan and to the Official Map, if any, and shall be considered in their relation to other existing and planned streets, to topographical conditions, to public convenience and safety and in their appropriate relation to the proposed uses of land to be served and/or abutted by such streets.
B. 
Where such is not shown in the Master Plan, the arrangement of streets in a subdivision shall either:
(1) 
Provide for the continuation or appropriate projection of existing streets in surrounding areas; or
(2) 
Conform to a plan for the neighborhood approved or adopted by the Planning Board to meet a particular situation where topographical or other conditions make continuance of or conformance to existing streets impracticable.
C. 
Laying of minor streets. Minor streets shall be so laid out that their use by through traffic will be discouraged.
D. 
Marginal access streets where subdivision abuts or contains arterial street. Where a subdivision abuts or contains an existing or proposed arterial street, the Planning Board may require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, deep lots with rear service alleys or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
E. 
Where a subdivision borders on or contains a railroad right-of-way or controlled-access highway right-of-way, the Planning Board may require a street approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts or for commercial or industrial purposes in appropriate districts. Such distances shall also be determined with due regard for the requirements of approach grades and future grade separations.
F. 
Reserve strips controlling access to streets, water plants, sewage treatment plants or to other land dedicated or to be dedicated to public use shall be prohibited except where control of such strips is definitely placed in the Town under conditions approved by the Planning Board.

Curb radii where connecting street lines deflect. When connecting street lines deflect from each other at any one point by more than 10°, they shall be connected by a curve with a radius at the inner street line of not less than 250 feet for minor and collector streets and of such greater radii as the Planning Board shall determine for special cases.
J. 
Street intersections. Streets shall be laid out so as to intersect as nearly as possible at right angles, and no street shall intersect any other street at less than 75°. Any change in street alignment to meet this requirement shall occur at least 100 feet from the intersection.
K. 
Radius of property at intersections. The Planning Board may require that property lines at street intersections shall be rounded with a radius of 10 feet or such greater radius when the Planning Board may deem such necessary. The Board may permit comparable cutoffs or chords in place of rounded corners.
L. 
Curb radii at intersections. Curb radii at street intersections shall be not less than 20 feet.
M. 
Right-of-way widths. Street right-of-way widths shall be shown as in the Master Plan, and, where not shown therein, such right-of-way widths shall be in conformance with the Highway Specifications of the Town of Boston.[1]

Dead-end streets shall be provided at the closed end with a turnaround having an outside roadway diameter of at least 121 feet and a street property line diameter of at least 150 feet. All turnarounds or culs-de-sac shall be designed to be completely paved so that there is no island in the middle of the circle and so that pavement drains from the middle of the circle to the outside edges.
P. 
Half streets. Half streets shall be prohibited except when essential for the reasonable development of the subdivision in conformity with the other requirements of these regulations, and, where the Planning Board finds it will be practicable to require the dedication of the other half street which is adjacent to a tract to be subdivided, the other half of the street shall be plotted within such tract.
Q. 
Street improvements. Street improvements shall be provided continuously from the existing improved street system up to and along the entire frontage of each lot upon which a dwelling is to be built. For corner lots, all street improvements shall be provided on the side street to the rear lot line of each corner lot upon which dwelling is to be built.
R. 
Street grade. All street grades shall conform with the Highway Specifications of the Town of Boston.[2]

S. 
Trees. Except for expressly provided by the Planning Board, no trees shall be planted or permitted to remain within the street right-of-way.
T. 
Street names. Street names will be chosen only after a careful study of street names in the Town to prevent duplication and phonetic conflicts. Street names shall be subject to the approval of the Town Board.

B. 
Width. The width of any alley shall not be less than 24 feet.
C. 
Intersections, sharp changes in alignment to be avoided. Alley intersections and sharp changes in alignment shall be avoided, but where necessary shall be provided with sufficient corner cutoffs to permit safe vehicular movement.

(1) 
Where a subdivision is traversed by a watercourse, drainageway, channel or stream, there shall be provided a stormwater easement of at least 20 feet in width for drainage right-of-way, conforming substantially with the lines of such watercourse, including its side banks, and such further width or construction, or both, as will be adequate for the purpose of maintenance. Parallel streets or roads may be required in connection therewith for access.
(2) 
Where storm sewers or ditches may be required to discharge across an adjacent property in order to drain into a natural watercourse or watershed in which the subdivision lies, the subdivider shall secure an easement from the adjacent property owners to assure uninterrupted discharge of drainage water from the subdivision. Such easement shall be of a dimension required by the Planning Board.
