The Folly Brook Local Protection Project is located in Wethersfield on Folly Brook, about 0.3 mile upstream of Wethersfield Cove. The project protects about 165 acres lying along both sides of Folly Brook. The land is primarily residential and urban, consisting of single family homes and a convalescent home.

Construction of the project began in October 1977 and was completed in October 1978 at a cost of $220,000. The Folly Brook project is a small project, built under Section 205 of the Corps’ Continuing Authorities Program. It is operated and maintained by Wethersfield. The Folly Brook project is a downstream extension of the Folly Brook conduit built as part of the Hartford Local Protection Project.

The project consists of 175 feet of corrugated metal pipe extending from the Folly Brook conduit (part of the Hartford Local Protection Project) to the lower end of Folly Brook in Wethersfield. The pipe passes under the Hartford Avenue Bridge and the Conrail Railroad Bridge and reduces the threat of flooding in Wethersfield.
