Spa Creek Stream Restoration Design Build
Completed in 2019 for Spa Creek Conservancy
The project includes the restoration of 5,000 linear feet of stream, beginning at an outfall that had been lined with gabions years earlier and ending at a stand of Phragmites established on a sediment deposit formed as a result of channel erosion and upland sediment transport into tidewater. The design involves removing gabions, creating step
pools to slow flows, and raising the channel bed to reconnect the stream to its floodplain. The floodplain reconnection allows stormwater to rehydrate non-tidal wetlands. The design also incorporates the excavation of two acres of Phragmites and restoration of emergent tidal wetlands.
