Whisper Way Storm Drainage Improvements Project

The project involves the removal of approximately 178 linear feet of two existing 24-inch CMP pipes, along with the demolition of a double wing catch basin, upstream headwall, and downstream headwall at the end of Whisper Way. These elements will be replaced with new storm drainage infrastructure, including two 36-inch RCP pipes of similar length, a double wing catch basin, and headwalls both upstream and downstream. The new pipes are to be installed at existing grades to avoid interference with existing utilities, with provisions made for positive drainage through tail ditches at both ends of the system. The work must be performed within limited easements—specifically, the right-of-way, a 20-foot permanent drainage easement, and a 30-foot temporary construction easement—while minimizing disturbance to existing driveways, curb, gutter, and pavement through the use of trench shoring methods. All new storm structures will include paved inverts as shown on the project drawings, and the contractor is responsible for locating and protecting existing utilities to prevent service interruptions during construction. The project is overseen by the City of Peachtree Corners, Georgia, with a response deadline of March 14, 2024, and the primary contact being Kevin Whigham.
