Certified soil erosion and sediment control regulations.
14.1
Application of Regulations.
a)
A Certified Soil Erosion and Sedimentation Control Plan shall be submitted with any development application when the disturbed area of such development is cumulatively more than one-half (½) acre, as determined by the Zoning Enforcement Officer.
b)
A soil erosion and sedimentation control plan for a one-family dwelling that is not part of a subdivision is not required. A standard construction entrance and a filter fence and/or hay bales down slope from any disturbed area is required for all new construction.
c)
Stockpiling of earthen materials on any lot for any purpose shall be protected by a filter fence and/or haybales.
14.2
Content of Soil Erosion and Sediment Control Plan.
a)
In general, a Certified Soil Erosion and Sedimentation Control Plan shall contain proper provisions to adequately control accelerated erosion and sedimentation and reduce the danger from storm water runoff on the site based on the best available technology. Such technology can be found in the 2002 Connecticut Erosion and Sediment Guidelines, latest edition. Alternative methods may be used if approved by the Planning and Zoning Commission.
b)
The Certified Soil Erosion and Sedimentation Control Plan shall include but not be limited to a narrative and a Site Plan. The narrative shall include a description of the development; the schedule for grading and construction activities to include start and completion dates, sequence of grading and construction activities, sequence for installation of erosion control measures, and sequence for final site stabilization; and the design criteria, construction details, installation procedures, and operations and maintenance procedures for erosion control and storm water management facilities.
c)
The Certified Soil Erosion and Sedimentation Control Plan shall be prepared by a Connecticut Licensed Professional Engineer at a sufficient scale to show property lines, existing and proposed contours, wetlands, watercourses, existing and proposed structures, and the location and design details for all proposed erosion control and storm water management facilities. The Town Engineer may require additional information as necessary.
14.3
Standards. In general, a soil erosion control plan shall result in a development that minimizes erosion and sedimentation during construction, is stabilized and protected from erosion when completed and does not cause unnecessary erosion and sedimentation. The minimum standards for individual erosion control measures shall be as specified in the latest edition of 2002 Connecticut Erosion and Sediment Guidelines. Determination of peak flow rates and volumes of runoff shall be taken from this same publication. The Planning and Zoning Commission, for sound technical reasons may grant exceptions from the standards of the those Guidelines.
14.4
Approval Conditions. The Planning and Zoning Commission may require surety for the installation and maintenance of erosion control and/or storm water control measures shown on an erosion control plan. The Planning and Zoning Commission shall require that the applicant perform monthly (as well as twenty-four (24) hours after a major rainfall event) inspections and report the results to the Commission.
