Stream restoration is a set of techniques or methods the County uses to protect properties and public infrastructure by reducing stream bank erosion, minimizing the down-cutting of stream beds, and restoring aquatic ecosystems (natural stream systems).
Restoration techniques typically use natural materials such as rocks, logs, and native plants to help slow down stormwater flow and restore the natural meander of curve pattern found in stable streams. They are usually done in larger scale projects utilizing large equipment to mobilize plants and rocks.
The Donnybrook restoration project occurred along approximately 2,000 linear feet of the stream. It involved the use of natural channel design principles, stream forest buffers, stormwater management facilities, and the planting of over 560 native trees and shrubs. The project required coordination with local residents and collaboration with the DOT to replace a pedestrian bridge widely used by the community. Look below for a series of before and after images that show how the stream was restored.
