SECTION 4.05- GRADING PLAN AND SOIL EROSION AND SEDIMENT CONTROL PLAN
When applicable a grading and soil erosion and sediment control plan shall be submitted. This plan shall
be at a scale not less than 1" = 40'. The area shown on the grading and soil erosion and
sediment control plan may be limited to the portion of the subdivision or re-subdivision
affected by the proposed regrading, cuts, fills, and/or soil and/or rock.
As a part of the grading plan all developers shall provide, using the best available
technology proper provisions for soil erosion and sediment control. A soil erosion and sediment
control plan shall be submitted with any application for subdivision when the disturbed area
is cumulatively more than one half acre. The Planning and Zoning Commission may also require that
a bond be posted assuring that the Grading and Soil and Erosion Control Plan is implemented.
The Planning and Zoning Commission may petition the Middlesex County Soil and Water Conservation
District for a study to establish that a Grading and Soil Erosion and Sediment Control Plan complies
with the minimum standards as set forth in Section.
- Minimum Standards for Soil Erosion and Sediment Control Provisions
The Developer is requested to use the publication, Connecticut Guidelines for Soil
Erosion and Sediment Control (latest edition), as amended, as a tool in providing all
the minimum information required for soil erosion and sediment control, peak flow rates,
and volumes of water runoff.
The Grading and Soil and Erosion Control Plan shall include but is not limited to, the following:
- A narrative describing the development, the schedule of major activities on the land,
(including start and completion dates, sequence of grading and construction activities,
sequence for installation of erosion and sediment control measures, and sequence for final
stabilization measures); the design criteria and construction and installation procedures for
soil erosion and sediment control measures and storm water management facilities; and
an ongoing maintenance program for erosion and sediment control measures and the storm water
- A site development plan as described in Section 4.02 showing the following additional
- Areas of major regrading, cuts, fill and/or soil and/or rock removal with estimated amount of
material to be added or removed and calculations of proposed cuts and fills;
- Existing (dashed lines) and proposed contours (solid lines) at an interval not exceeding
two (2) feet based on field and aerial survey as well as existing spot elevations
- The location of and design details for all proposed soil erosion and sediment control
measures and storm water management facilities;
- Areas in excess of 25% natural slope highlighted with cross hatching;
- Existing and proposed drainage swales, wetlands and water courses;
- Existing permanent buildings and structures, including well and septic locations;
- Notes indicating if blasting will be required;
- Cross section drawings covering proposed excavation areas;
- Hydraulic computations for all culverts and bridges, stream crossings and detention/retention
- Any other information deemed necessary and appropriate by the developer or requested by the
Commission or its designated agent.
Approval of the subdivision shall constitute certification that the Grading and Soil Erosion
and Sediment Control Plan complies with the requirements and purpose of these regulations.
After approval of the subdivision, no site development shall begin unless the soil erosion
and sediment control measures and facilities in the plan scheduled for installation prior
to site development are installed, functional, and maintained until the development is complete.
4.05.02 Inspection and Enforcement
The Zoning and Inland Wetlands Enforcement Officer (ZEO) and the Public Works Department
shall make periodic inspections to ensure compliance with the approved plan and that control
measures and facilities are properly performed or installed and maintained. Upon finding improper
installation or maintenance, The City has the authority to require compliance to the plan and/or
order the contractor/developer to stop work. the Commission may ask for progress reports
from the developer and/or the Zoning Enforcement Officer.
