About the Project

The 17th St./W. Locust St. storm sewer capacity improvement project is one phase of the Bee Branch Watershed Flood Mitigation Project. The purpose of the project is to increase the capacity of the storm sewer from the Lower Bee Branch Creek up 17th St. to W. Locust St. and continuing up W. Locust St. toward Kirkwood St.

A larger storm sewer and additional high-capacity storm drains will help alleviate the flash flooding frequently experienced on these streets. The estimated completion of the entire project is 2021. For more information, visit
