[Amended 7-24-2017]
Stone or approved reinforced concrete bounds shall be placed
on both sides of the street at all angle points, at the beginning
and end of all curves, and at all intersections of streets and ways.
Intermediate bounds must be set where the distance between bounds
would otherwise exceed 500 feet. Bounds shall be not less than three
feet in length and not less than six inches in width and breadth.
No permanent monuments or bounds shall be installed until all construction,
which would destroy or disturb the monuments, is completed and the
top of the bounds shall be set to finished grade. The bounds are to
be set by a land surveyor who shall certify in writing that they conform
to the approved subdivision plan. Bounds shall also be set for all
front lot corners before utilities are installed to ensure accurate
measurement for utility location. All street monuments are to be accurately
tied into three or more suitable objects selected for their durability
and prominence. This information is to be provided to the Town Engineer
on a copy of the street layout or the subdivision plan.
[Amended 12-13-2021]
When vertical or slope block granite street curbing is required,
it shall be in accordance with the standards set forth below. Vertical
granite curbing shall be used on the inside radius of all culs-de-sac
and curves with a radius of 60 feet or less. Cape Cod berm when specified
shall be used throughout, except that vertical granite curb inlets
with appropriate inclined transition sections (of vertical granite)
shall be provided at all catch basins. The curb inlet and catch basin
installation shall conform to the typical curb inlet detail drawing.[1]
A.
Granite curbs; general. Curbstone shall be of hard and durable granite,
or a light color satisfactory to the Engineer, free from seams which
impair its structural integrity, and of a good smooth splitting appearance.
Granite shall come from approved quarries and, when tested, shall
have a Los Angeles percentage of wear not more than 32. Test samples
shall be hand broken.
B.

true plane.
(b)
Exposed arris lines shall be pitched straight and true with
no variation from a straight line greater than 1/8 of an inch.
(c)
Back surfaces of curbstones shall have no projection for a distance
of three inches down from the top, which would exceed a batter of
four inches in 12 inches.
(d)
Front face shall be at right angles to the plane of the top
and shall be smooth quarry split. Drill holes in exposed part of face
will not be permitted.
(e)

Editor's Note: See Appendix B included as an attachment to this chapter.
A driveway opening is to be left in front of each lot at the best suited location and is to be shown on the road detail plan. A five-foot minimum inclined transition section of vertical granite curbing is to be set at each side of the driveway opening whenever granite curbing is installed. Minimum curb opening is to be 15 feet. Abandoned curb cuts must have required curbing installed and sealed. Changes in the location of curb cuts from that shown on the definitive plan may be considered a modification of the approved plan and must receive the approval of the Board in writing, whether a major or minor change (see § 405-8I).
Street signs to specification of the Superintendent of the DPW
are to be furnished and installed for every intersection by the developer.
The developer shall maintain street signs until the Town accepts the
ways. Said signs are required to be installed by the developer following
the installation of the base course of the roadway, and prior to issuance
of building permits. In the event that the covenant is released by
the posting of surety, the applicant shall place at least temporary
street signage at all intersections until the base course, as required
above, is completed. In addition to the sign stating the name of the
street, the applicant shall be responsible for installing a sign beneath
the street name that reads "Not a Town Way." This sign shall remain
in place until the Town accepts the street.
A.
Approval of the definitive plan does not constitute the layout or
acceptance by the Town of streets shown on the plan.
B.
The developer shall provide a street layout plan suitable for recording
containing all necessary information for Town acceptance of the streets.
This street layout plan shall be provided prior to the release of
security for the subdivision.
C.
After completion of construction, the developer shall execute an
instrument, in a form acceptable to Town Counsel, transferring to
the Town, without cost, valid unencumbered title to the right-of-way
and all utilities installed therein, the drainage system, including
any drainage lots and/or easements, and any other easements associated
with the subdivision.
D.
The Board shall retain a minimum of $10,000 surety or one lot for
a period not to exceed 24 months after completion of the subdivision
and the submittal of as-built and street acceptance plans acceptable
to the Planning Board and Town Engineer or until the streets are accepted
by the Town, whichever comes first. After this date, the Board shall
return the remainder of the security to the person or persons who
furnished the same.
E.
Once street acceptance plans have been submitted and approved by the Town, the developer shall be responsible for petitioning the Select Board and Department of Public Works to accept the streets. The developer shall be responsible for repairing all damage to constructed ways and municipal services within the roadway layout and shall be responsible for maintaining all landscaping for the time periods set forth in Subsection D.
[Amended 10-18-2021 STM by Art. 32]
Prior to final release of his security, the developer shall
provide the Town with as-built plans of all roads, drainage systems,
etc., on durable material from which contact print copies can be made.
These plans shall show the precise location, size, type, etc., of
all required construction, as built, and shall include, but not be
limited to, the components of water, sewer, and drainage system, other
public utilities, elevations, slopes, street layout monuments, etc.,
as necessary to show that design requirements have been met and changes
documented. These plans shall be certified by the designing engineer
that the information shown correctly represents the construction as
built.
The entire area of the subdivision shall be cleaned of all dirt,
debris, construction materials, etc., leaving a neat and presentable
appearance. The complete storm drainage system, including catch basins,
manholes and pipes, shall be properly cleaned and free of debris.
[Amended 7-24-2017]
No certificate of occupancy may be applied for, or issued by
the Building Commissioner, with respect to any structure erected on
any lot located in an approved subdivision until the Board has certified
that the ways and municipal services designed to serve such lot have
been constructed and installed in accordance with these rules and
regulations.
No new subdivision which will relocate or eliminate existing
streets of record will be approved until the applicant has provided
proof that said streets are clear in title and free of all encumbering
rights of others.
