The project included the installation of an underground storm drain system on Mary St. The new system relieves pressure on the older storm drain system and reduces the risk of flooding by adding capacity to the storm drain system.

Current Status

This project has been completed and is currently in the warranty period.

Project Scope

This project included the construction of an underground storm drain system on Mary Street from East Bouldin Creek to Newton Street. The new system connects to a culvert underneath the bridge on Mary Street. We also replaced two inlets on Mary St. 


$750,000 from the Drainage Utility Fund and the Regional Stormwater Management Program.
