§ 118-1120 Soil erosion and sediment control regulations.
[Added effective 10-26-2012]
§ 118-1121 Purpose.
The purpose of these regulations is to help minimize soil erosion and sedimentation that occurs as a result of the construction of residential, industrial and commercial development. Rapid changes in land use to nonagricultural and urban uses have accelerated soil erosion and sediment deposition, resulting in water pollution and damage not only to aesthetic values and wildlife but to sewers, roads, stream channels and water bodies.
§ 118-1122 Activities requiring a certified erosion and sediment control plan.
A soil erosion and sediment control plan shall be submitted with any application for development when the disturbed area of such development is cumulatively more than one-half (1/2) acre.
§ 118-1123 Exemptions.
A single-family dwelling that is not part of a subdivision of land shall be exempt from these soil erosion and sediment control regulations.
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. The Connecticut Guidelines for Soil Erosion and Sediment Control (1985), as amended describes the principles, methods and practices necessary for certification. Alternative principles, methods and practices may be used with prior approval of the Commission.
The proposed area alterations, including cleared, excavated, filled or graded areas, and proposed structures, utilities, roads and, if applicable, new property lines.
Plans for soil erosion and sediment control shall be developed in accordance with these regulations using the principles as outlined in Chapters 3 and 4 of the Connecticut Guidelines for Soil Erosion and Sediment Control (1985), as amended. 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 off-site erosion and/or sedimentation.
The minimum standards for individual measures are those in the Connecticut Guidelines for Soil Erosion and Sediment Control (1985), as amended. The Commission may grant exceptions when requested by the applicant if technically sound reasons are presented.
The appropriate method from Chapter 9 of the Connecticut Guidelines for Soil Erosion and Sediment Control (1985), as amended, shall be used in determining peak flow rates and volumes of runoff, unless an alternative method is approved by the Commission.
The Commission, or its designated agent, shall either certify that the soil erosion and sediment control plan, as filed, complies with the requirements and objectives of the regulations or deny certification when the development proposal does not comply with these regulations.
Nothing in these regulations shall be construed as extending the time limits for the approval of any application under the provisions of Chapters 124, 124A or 126 of the Connecticut General Statutes.
Prior to certification, any plan submitted to the municipality may be reviewed by the Fairfield County Soil and Water Conservation District which may make recommendations concerning such plan, provided that such review shall be completed within thirty (30) days of the receipt of such plan.
The Commission shall forward a copy of the development proposal to the Conservation Commission, or other review agency or consultant, for their review and comment within thirty (30) days of the receipt of the plan.
§ 118-1127 Conditions relating to soil erosion and sediment control.
Any person engaged in development activities who fails to file a soil erosion and sediment control plan in accordance with these regulations or who conducts a development activity, except in accordance with the provisions of a certified plan shall be deemed in violation of these regulations.
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 financial guarantee approved as to form and financial institution by the Commission or Corporation Counsel and submitted prior to the start of construction in accordance with and the provisions specified in § 118-1450, Special Permits, and § 118-1451, Site plan review. Such financial guarantee shall be released only after all improvements are complete and are in satisfactory condition. If not satisfactory, within 65 days of release request, a written explanation shall be provided to the applicant detailing the outstanding work that must be completed before such financial guarantee or portion thereof may be released.
Site development shall not begin unless the soil erosion and sediment control plan is certified and those control measures and facilities in the plan scheduled for installation prior to site development are installed and functional.
All control measures and facilities shall be maintained in effective condition to ensure the compliance of the certified plan.
§ 118-1128 Inspection.
Inspection shall be made by the Commission, or its designated agent, during development to ensure compliance with the certified plan and that control measures and facilities are properly performed or installed and maintained. The Commission 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 certified plan and are being operated and maintained.
