It is the purpose of this regulation to carry
out the mandate of the Connecticut Legislature in Public Act 83-388
codified in §§ 22a-325 through 22a-329 of the General
Statutes to provide for proper regulations concerning soil erosion
and sediment control during development. These regulations are meant
to provide minimum requirements by inclusion or reference for soil
erosion and sediment control plans:
A.
To prevent costly repairs to gullies, washed out fills,
roads and embankments;
B.
To prevent sediment from polluting water bodies and
wetlands;
C.
To prevent degrading of aesthetic, recreational, fish
and wildlife values;
D.
To prevent clogging of storm sewers and road ditches
that reduce capacities and cause flooding and damage to adjoining
properties; and
E.
To prevent erosion that destroys the soils' capabilities
to support vegetation.
As used in this article, the following terms
shall have the meanings indicated:
A signed written approval by the Commission (or its designated
agent) that a soil erosion and sediment control plan complies with
the applicable requirements of these regulations.
The North Central Conservation District, Inc., which was
formed by combining the Hartford County and Tolland County districts,
established under Subsection (a) of CGS § 22a-315.
[Amended 1-4-2019]
Any construction or grading activities to improved or unimproved
real estate.
An area where the ground cover is destroyed or removed leaving
the land subject to accelerated erosion.
The detachment and movement of soil or rock fragments by
water, wind, ice or gravity.
Any excavating, grubbing, filling (including hydraulic fill)
or stockpiling of earth materials or any combination thereof, including
the land in its excavated or filled condition.
The periodic review of sediment and erosion control measures
shown on the certified plan.
Solid material, either mineral or organic, that is in suspension,
is transported, or has been moved from its site of origin by erosion.
Any unconsolidated mineral or organic material of any origin.
A scheme that minimizes soil erosion and sedimentation resulting
from development and includes, but is not limited to, a map and narrative.
A soil erosion and sediment control plan shall
be submitted as part of any application for development when the disturbed
area of such development is cumulatively more than 1/2 acre.
A.
To be eligible for certification, a soil erosion and
sediment control plan shall contain proper provisions to adequately
control accelerated erosion and sedimentation and reduce the danger
from stormwater runoff on the proposed site based on the best available
technology. Such principles, methods and practices necessary for certification
are found in the 2002 Connecticut Guidelines for Soil Erosion and
Sediment Control.
B.
Said plan shall contain, but not be limited to:
(1)
A narrative describing:
(a)
The development.
(b)
The schedule for grading and construction activities
including:
(c)
The design criteria for proposed soil erosion
and sediment control measures and stormwater management facilities.
(d)
The construction details for proposed soil erosion
and sediment control measures and stormwater management facilities.
(e)
The installation and/or application procedures
for proposed soil erosion and sediment control measures and stormwater
management facilities.
(f)
The operations and maintenance program for proposed
soil erosion and sediment control measures and stormwater management
facilities.
(2)
A site plan map at a sufficient scale to show:
(a)
The location of the proposed development and
adjacent properties;
(b)
The existing and proposed topography, including
soil types, wetlands, watercourses and water bodies;
(c)
The existing structures on the project site,
if any;
(d)
The proposed area alterations, including cleared,
excavated, filled or graded areas and proposed structures, utilities,
roads and, if applicable, new property lines;
(e)
The location of and design details for all proposed
soil erosion and sedimentation control measures and stormwater management
facilities identified by standard symbols and nomenclature shown in
the 2002 guidelines;
(f)
The sequence of grading and construction activities;
(g)
The sequence for installation and/or application
of soil erosion and sediment control measures;
(h)
The sequence for final stabilization of the
development site.
(3)
Any other information deemed necessary and appropriate
by the applicant or requested by the Commission or its designated
agent.
A.
Plans for soil erosion and sediment control shall
be developed in accordance with these regulations using the principles
as outlined in the 2002 Connecticut Guidelines for Soil Erosion and
Sediment Control. Soil erosion and sediment control plans shall result
in a development that minimizes erosion and sedimentation during construction,
is stabilized and protected from erosion when completed, and does
not cause significant off-site erosion and/or sedimentation.
B.
The minimum standards for individual measures are
those in the 2002 Connecticut Guidelines for Soil Erosion and Sediment
Control, as amended. The Commission (or its designated agent) may
grant exceptions when requested by the applicant if technically sound
reasons are presented.
C.
For soil erosion and sediment control measures requiring
engineered measures per the 2002 Connecticut Guidelines for Soil Erosion
and Sediment Control as amended, calculations by a Connecticut professional
engineer shall be used in determining peak flow rates and volumes
of runoff.
A.
The Suffield Zoning and Planning Commission or its
agent shall by its approval certify that the soil erosion and sediment
control plan complies with the requirements and objectives of this
regulation.
B.
Nothing in these regulations shall be construed as
extending the time limits for the approval of any application under
Chapter 124 or 126 of the General Statutes.
[Amended 1-4-2019]
C.
Prior to approval, any plan submitted to the Town
may be reviewed by the North Central Conservation District which may
make recommendations concerning such plan, provided such review shall
be completed within 30 days of receipt of such plan.
A.
The estimated costs of measures required to control soil erosion and sedimentation, as specified in the certified plan, that are a condition of certification of any modified site plan may be required to be covered in a performance bond or other assurance acceptable to the Commission in accordance with the provisions specified under § 315-118 of the regulations.
B.
Site development shall not begin unless the soil erosion
and sediment control plan is approved and those control measures and
facilities in the plan scheduled for installation prior to site development
are installed and functional.
C.
Planned soil erosion and sediment control measures
and facilities shall be installed as scheduled according to the approved
plan.
D.
All control measures and facilities shall be maintained
in effective condition to ensure compliance with the approved plan.
A.
Inspection shall be made by the Commission or its
designated agent during development to ensure compliance with the
approved plan and that control measures and facilities are properly
performed or installed and maintained. The Commission or its designated
agent may require the permittee to verify through progress reports
that soil erosion and sediment control measures and facilities have
been performed or installed according to the approved plan and are
being operated and maintained.
B.
Modifications to plans may be necessary and field
changes may be required in the event that upon inspection it is found
that the intent of the regulations is not being met.
