New Britain, CT Environmental Rules: Erosion Control (2026)

Section 230-145, the Soil Erosion and Sediment Control Regulations for Land Development of the City of New Britain, was adopted in 1985 under the state's Public Act 83-388 and still governs every disturbance-triggering project today. Section 230-145-10.30 sets the trigger: no land development that is cumulatively more than one-half acre in area may proceed in any district until the City Plan Commission or its appointed agent certifies a soil erosion and sediment control plan for it. Section 230-145-20.10 restates the same half-acre threshold specifically for the plan submission requirement, tying it to the application for development rather than to the parcel's total size.

Section 230-145-30.10 carves out one clear exemption: a single-family dwelling that is not part of a subdivision of land does not need a certified plan, even if the disturbed area exceeds half an acre. For everything else, Section 230-145-40 requires the plan to contain a narrative describing the development, a construction and grading schedule, design and installation details for erosion and sediment control measures and stormwater management facilities, and a surveyed site plan at a scale of at least 1 inch to 40 feet. Section 230-145-50 ties the plan's technical standards to the Connecticut Guidelines for Soil Erosion and Sediment Control (1985), letting the Commission approve alternate methods only with a technically sound justification.

Section 230-145-70.10 backs certification with a completion bond or other assurance the Commission accepts, sized from a cost breakdown the applicant submits with the application, and Section 230-145-70.20 bars site work from starting until that bond is posted and the plan is certified. Section 230-145-80 lets the Commission or its agent inspect the site during construction and release the bond only once a final report and inspection confirm the certified measures were installed as approved.
