Stream Repairs in Raleigh Protect the Environment
Why Stream Repairs Matter
Stream repairs can provide several benefits, like improving water quality and stream health and protecting properties from issues caused by unstable streams. Repairs are designed to allow a stream to flow as naturally as possible while reducing streambank erosion and harmful flooding. Also, a stream that is stable leads to less water pollution and limits impacts to wildlife.
How Does It Work?
Many techniques are used to repair streams. The stream at Millbrook Exchange Park is being done with a unique and low-cost design that includes placing small rock structures in the stream that will naturally fill in with sediment (i.e. sand and gravel) over time. This will gradually raise the stream bed to a more natural, functional level while reducing the amount of sediment moving downstream, transforming the energy of the stream, and reducing future stream erosion.
Part of the stream along Greywood Drive in the Brentwood Today neighborhood is being restored by regrading, or leveling the soil in the stream, and reshaping the stream channel. The design also includes installing features that mimic natural stream conditions. This will make the stream healthier and more capable of handling stormwater flows when it rains.
