Stream Restoration and Environmental Restoration
|Since its completion nearly ten years ago, the Hidden Valley Ecological Garden / Wellingford Street project has matured nicely. The stream banks are stable and the plants added to the floodplain are thriving.
This project was designed to reduce storm water pollution and erosion, prevent localized flooding and enhance the surrounding community and environment.
Extended maintenance and water quality monitoring continue.

Storm Water Services also reduced flood losses by purchasing 20 parcels of land and tearing down 16 homes that had repeatedly flooded. The buyouts provided 13 acres of permanent open space in the floodplain.

Tackling Little Sugar's big problems
This project is located in the headwaters of Little Sugar Creek. It is one of a series of initiatives to improve water quality in a creek surrounded by dense development.
The major goals of the Hidden Valley project were to improve water quality and aquatic habitat by restoring the stream and by retrofitting storm water wetlands and other BMPs in the surrounding floodplain.
The natural twists and turns of Little Sugar Creek were restored and buffers were added along the banks. Trees and shrubs planted in the buffers reduce erosion and provide a place for wildlife to live.
A series of stormwater wetlands and wet ponds was created along Wellingford Street and Mellow Drive. The wetlands remove some pollutants from storm water and can reduce some flood risks by temporarily storing and releasing excess water. A total of 31,000 trees, bushes and other plants were added in the project area.
Currently, all wetland plants in this project are growing faster than expected. Schools of fish, minnows, insects, frogs, mussels, and many more wildlife species are increasingly present throughout the stream restoration project.
