A soil erosion and sediment control plan at the same scale as
the site plan, which meets the design requirements of this Bylaw,
shall be prepared and submitted to the Department of Public Works.
The plan shall include, but not be limited to, the items listed below
and, at a minimum, be designed to provide sufficient information to
evaluate the effectiveness and acceptability of measures proposed
for soil erosion and sediment control during construction to protect
the environment, public welfare/health, and municipal facilities and
utilities. The following information shall be detailed on the plan:
A.
Name, address and telephone number of owner, civil engineer and person
responsible for implementation of the plan.
B.
Property lines.
C.
Location of all existing and proposed building and impervious surfaces.
D.
Location of all existing and proposed stormwater utilities, including
structures, pipes, swales and detention basins.
E.
Soil erosion and sediment control provisions, including explanation
of technical basis used to select the practices chosen to minimize
on-site erosion and prevent off-site sediment transport, including
provisions to preserve topsoil and limit disturbance.
F.
Design details for both temporary and permanent erosion control structures.
G.
The Director may require any additional information or data deemed
appropriate and/or may impose such conditions thereto as may be deemed
necessary to ensure compliance with the provisions of this Bylaw and
regulations for the preservation of public health and safety.
H.
An attached vicinity map showing the location of the site in relationship
to the surrounding area's watercourses, water bodies and other
significant geographic features, and roads and other significant structures.
I.
Suitable contours for the existing and proposed topography.
J.
A clear and definite delineation of any areas of vegetation or tree
disturbance. Note all vegetation that is to be removed and all vegetation
that is to be saved.
K.
A clear and definite delineation of any wetlands, natural or artificial
water storage detention areas, and existing drainage ditches on the
site.
L.
A description of construction and stockpile and/or excess materials
removed from the site expected to be stored on site. The plan shall
include a description of controls to reduce pollutants from these
materials, including storage practices to minimize exposure of the
materials to stormwater.
M.
A sequence of construction for the development site, including stripping
and clearing; rough grading; construction of utilities, infrastructure,
and buildings; and final grading and landscaping. Sequencing shall
identify the expected date on which clearing will begin, the estimated
duration of exposure of cleared areas, areas of clearing, and establishment
of permanent vegetation.
A construction project shall be considered in conformance with
this Section if construction means and methods have been effective
in preventing soils or other eroded matter from being deposited onto
adjacent properties, rights-of way, public storm drainage system,
or wetland or watercourse. The design, testing, installation, and
maintenance of soil erosion and sediment control operations and facilities
shall adhere to the standards and specifications contained in the
Massachusetts Erosion and Sediment Control Guidelines for Urban and
Suburban Areas, dated March 1997, reprint 2003, as it may be amended
from time to time, and in accordance with the latest version of the
current edition of the Massachusetts Stormwater Handbook, and EPA's
current Construction General Permit (CGP).
A.
A soil erosion and sediment control plan review is triggered by a
site development plan and/or a building permit application or other
activity that falls within the jurisdiction of this Bylaw. Applicants
shall be referred by the permit-issuing agency to the Department of
Public Works to conduct the soil erosion and sediment control plan
review. Activities that fall within the jurisdiction of this Bylaw
that do not require a permit from any Town department are not exempt
from this provision. In this situation, the applicant must seek a
soil erosion and sediment control plan review directly from the Department
of Public Works.
B.
The Department of Public Works will review each soil erosion and
sediment control plan to determine its conformance with the provisions
of this Bylaw. The Department of Public Works shall, in writing:
(1)
Approve the plan as submitted; or
(2)
Approve the plan subject to such reasonable conditions as may be
necessary to secure substantially the objectives of this regulation,
and issue the permit subject to these conditions; or
(3)
Disapprove the plan, indicating the reason(s) and procedure for submitting
a revised application and/or submission.
C.
Approval of the soil erosion and sediment control plan shall remain
in effect for a term of one year. After one year, the owner must apply
to the Director for an extension, which will be approved at the Director's
discretion and in accordance with the Director's requirements.
