[Amended 6-23-2009; 4-26-2016]
The following classes of streets are established for planning
and design purposes. The Planning Board reserves the right to make
the final decision regarding the classification of a street based
on projected traffic volume and for reasons of public safety.
COLLECTOR STREET
A street that receives and distributes traffic to and from
various sub-areas within a neighborhood or receives traffic from a
given neighborhood and carries it to an arterial highway.
LOCAL STREET
A street used primarily for access to the abutting lots.
All streets in the subdivision shall be designed so that, in
the opinion of the Board, they will provide safe vehicular travel.
Due consideration shall also be given by the subdivider to the attractiveness
of the street layout in order to obtain the maximum livability and
amenity of the subdivision.
A. Design speeds. Radius of curves and length of vertical curves should
be selected to provide safe sight distances (either passing or stopping)
for the design speed of the road.
[Amended 5-2-2000]
B. Location and alignment.
(1) Master Plan. The proposed streets and off-street footpaths shall
conform, so far as practicable, to the Master Plan as adopted in whole
or in part by the Planning Board.
(2) Projections. Provision satisfactory to the Planning Board shall be
made for the proper projection of streets for access to adjoining
property that is not yet subdivided, or for connection with future
streets.
(3) Reserve strips. Reserve strips prohibiting access to streets or adjoining
property shall not be permitted, except where, in the opinion of the
Board, such strips shall be in the public interest.
(4) Jogs. Street jogs with center-line offsets of less than 125 feet
shall be avoided.
(5) Curves. The minimum center-line radii of curved streets shall be
200 feet for collector streets and 100 feet for local streets.
(6) Intersections. Streets shall be laid out so to intersect as nearly
as possible at right angles. No street shall intersect any other street
at less than 80°.
(7) Fillets. Property lines at intersections shall be rounded or cut
back to provide for a minimum radius at the edge of the pavement of
40 feet. The distance between the edge of the pavement and the property
line shall not be less than 15 feet for collector streets and 12 feet
for local streets.
(8) No exit streets.
[Amended 4-30-2002]
(a)
No exit streets shall not be designed or intended to serve more than eight lots or dwelling units. Streets which may be extended by the action of others so as to be through streets may be considered by the Board after reviewing the nature of the adjoining land and other local conditions. In no case shall a no exit street exceed 800 feet measured from the center of an intersection with another street except as allowed by the Board for Flexible Residential Development (§
185-23).
[Amended 6-23-2009]
(b)
No exit streets shall be provided at the closed end with a turnaround
having an outside roadway diameter of at least 100 feet.
(9) Bridges. New bridges shall be constructed in such manner as to comply
with plans and specifications as shall be in accordance with MGL c.
85, § 35, for bridges on public highways and shall be approved
by the Massachusetts Department of Transportation.
[Amended 4-26-2016]
(a)
Culverts in accordance with Massachusetts River and Stream Crossing
Standards.
[Amended 5-2-2000]
Before approval of a plan the Planning Board shall require the
plan to show a park or parks suitably located for playground or recreation
purposes or for providing light and air. The park or parks shall not
be unreasonable in area in relation to the land being subdivided and
to the prospective uses of such land. The Board may by appropriate
endorsement on the plan require that no building be erected upon such
park or parks without its approval for a period of three years. A
suggested formula is 10% of the total land area, not including wetlands.
For the purposes of these regulations, open space is land that is
usable for passive or active recreational activities, but not including
wetlands, water bodies, slopes in excess of 25% or land devoted to
buildings, impervious surfaces, roads and/or other development.
