Erosion Control Bond - Town of Cornwall, CT in Connecticut

Brief Summary

In Cornwall the erosion control bond amount is not a fixed number. It comes from your own estimate of what the erosion and sediment controls will cost, plus a contingency the town caps at 10 percent. A tight, realistic estimate keeps the bond, and the premium on it, as small as the regulations allow.

The Cornwall Planning and Zoning Commission may require a bond with surety as a condition of a Site Plan or Special Permit approval, to guarantee proper erosion and sediment controls during construction. Under Sections 8.5 and 8.12 of the Cornwall Zoning Regulations, the amount may not exceed the anticipated actual cost of the controls plus a contingency of no more than 10 percent, and no zoning permit issues until the bond is received.

How to Apply for a Erosion Control Bond:

• Prepare an Erosion and Sedimentation Control Plan, with a map and narrative, if cumulative land disturbance will exceed one half acre.
• Provide the Planning and Zoning Commission an estimate of the erosion controls and site improvements to be bonded.
• Receive the Commission's approval with the bond amount set as a condition.
• Have the bond executed with the Town of Cornwall as obligee in the amount the Commission sets.
• Deliver the bond to the Land Use Office before the zoning permit is issued.
• Request full or partial release from the Commission once the controls and improvements are complete.

Detailed Information About the Connecticut Erosion Control Bond:

How the amount is set

Applicants are often looking for a standard figure. Cornwall does not use one. Sections 8.5 (Site Plans) and 8.12 (Special Permits) of the Zoning Regulations, revised to December 1, 2025, have the applicant provide an estimate of the improvements to be bonded. The guarantee is then calculated so it does not exceed the anticipated actual costs of completing the improvements or implementing the erosion controls, plus a contingency not to exceed 10 percent of those costs. The regulations cite PA 12-182 as the authority.

When it comes up

The bond is a condition the Commission may attach when it approves a Site Plan or a Special Permit. It covers two things: timely completion of site improvements that will be conveyed to or controlled by the town, and proper implementation of any erosion and sediment controls required during construction. If total land disturbance will exceed one half acre cumulatively, an Erosion and Sedimentation Control Plan is required, prepared under the Connecticut Guidelines for Erosion and Sedimentation Control and the Soil Erosion and Sediment Control Act cited in the regulations.

The bond comes before the permit

No zoning permit is issued for the project until the bond is received. Ground cannot be broken on the approval alone.

Getting it back

The bond is held until the Commission votes to release it, in full or in part. Partial release is available as work is completed, so staged projects do not have to carry the full amount to the end. Confirm the current bond form and filing steps with the Cornwall Land Use Office before the bond is issued.
