Construction details and specifications shall comply with the standards
contained in the construction specifications and standards volume which is
available from the Engineering Section of the Barnstable Department of Public
Works for a nominal fee.
The erosion control plan shall include the use of erosion control measures
recommended by the Soil Conservation Service for use during and after construction.
A. Erosion minimalization. Stripping of vegetation, soil
removal and regrading shall be accomplished so as to minimize erosion.
B. Duration of exposure. The duration of exposure of disturbed
area shall be kept to a practical minimum.
C. Temporary erosion control. Temporary vegetation and/or
mulching shall be used to protect exposed critical areas during development.
D. Permanent erosion control installation. Permanent (final)
vegetation and mechanical measures to stabilize the land surface and control
erosion shall be installed as soon as practicable after construction ends.
E. Protection of permanent drainage facilities. Until a
disturbed area is stabilized, permanent drainage facilities, including but
not limited to catch basins, pipes, retention basins, grass swales and infiltration
devices, shall be protected from sediment in runoff water by the use of temporary
drainage facilities such as debris basins, sediment basins, silt traps or
other acceptable methods.
F. Dust control. During grading operations, methods of dust
control shall be employed wherever practicable.
All fill material which may be required within the exterior lines of
the way up to the twelve-inch gravel foundation shall be of clean gravel or
other suitable material as approved by the engineer and compacted to 95% of
the maximum dry density as determined by modified Proctor Test, in accordance
with ASTM-1557, Method D. All utilities including but not limited to storm
drains, subdrains and drainage structures and sewers if required within the
way lines shall be installed prior to the completion of the fill. This shall
include the installation of each service pipe, sleeve or conduit to the front
lot line of each lot in the subdivision. Upon completion of the fill and the
backfill of all service trenches, the work will be inspected by the Board's
engineer. Subsequent work shall not commence until the engineer has approved
the fill as acceptable for the application of the roadway foundation material.
Street trees, with a caliper of not less than 2 1/2 inches in diameter, and of a species approved by the Tree Warden, shall be planted on each side of every street in the subdivision wherever, in the opinion of the Planning Board, existing woodlands or individual trees are absent or not retained. Trees shall be located outside the exterior roadway lines unless located in green strips (see §
801-29D), at thirty-foot intervals unless otherwise specified by the Tree Warden in accordance with general practice in the Town. At the discretion of the Board, an easement, of such width as requested, outside the exterior way lines may be required for the planting of trees.
The area outside the traveled way in cut areas shall be sloped at a
rate not steeper than three to one until it intersects the finished grade
of the abutting lots, except as may be required for sidewalks. All such slopes
shall be loamed and seeded as previously required for grass plots.
Guardrails shall be installed where warranted as indicated on the figure
in the Appendix and where required by the Board. Guardrails on major and secondary
roads shall be steel beam highway guardrail Type SS in accordance with the
Massachusetts Highway Department standards. On minor roads and in Historic
Districts, steel-backed wood rail in accordance with the National Park Service
either/or ASHTO standards may be used in the place of steel beam guardrails
where permitted by the Board.
Granite or reinforced concrete bounds shall be set at all street intersections
at all points of change in direction or curvature of streets, at all front
corners and at other points where, in the opinion of the Board permanent monuments
are necessary, but in no case more than 500 feet apart. Monuments shall be
at least five inches by five inches by 30 inches. The cap shall be as specified
by the Board. The bounds shall otherwise conform to the Department's
specifications and shall not be set until all construction which could disturb
the monument is completed. After setting, the location of the bounds shall
be certified by a licensed land surveyor.
Street signs of the reflecting type specified by the Department of Public
Works and bearing the names of the intersecting streets, as indicated on the
definitive plan, shall be erected at all intersections of streets in the subdivision.
Such signs shall be subject to the approval of the Board. Temporary wood signs
with black letters stenciled on to a white background shall be installed on
all roads in the subdivision at the beginning of clearing for construction
of the road. Temporary signs shall be maintained and replaced as necessary
until the permanent signs are installed. Permanent street signs must be installed
after the road shoulders are loamed and seeded, and an acceptable stand of
grass has grown.
The entire area of the subdivision shall be cleaned up so as to leave,
in the opinion of the Board, a neat and orderly appearance free from debris
and other objectionable materials. All catch basins and manholes shall be
cleaned out. Following the completion of this and other items of work as required
herein, a final inspection will be made.
If released from restrictions with regard to sale of lots or buildings on lots by the posting of a performance bond or other security, the applicant shall maintain the roadway for vehicular traffic in a manner satisfactory to the Board. Further, the applicant shall maintain the roadway in a subdivision in a condition which meets all the above requirements to the satisfaction of the Board either until acceptance of the way by vote of the Town, or for a period of one year from the date of release of the security. A retainage fee is required to cover this period of time. See §
801-24P.
