Hollow Run at Nixon Park Design/Build Stream & Buffer Restoration ProjecT
This stream restoration project consisted of restoring approximately 1,250 linear feet of Murray Run adjacent to the pebble creek apartments in Roanoke County, VA. This project was undertaken to improve water quality and protect existing infrastructure. The stream was exhibiting signs of channelization, stream channel down-cutting, vertical eroding stream banks, and a lack of adequate riparian buffer vegetation.
The restoration plans, designed by Ecosystem Services, included the construction of a new channel geometry, floodplain, floodprone benches, specialized structures and treatments (constructed riffles, j-hooks, rock/log sills, imbricated wall, soil lifts) and the planting of stream banks and riparian buffer.
Ecotone was responsible for implementing the stream restoration design. In order to reduce project costs and increase the sustainability of the project, Ecotone suggested design alterations such as including toe wood structures and reducing the amount of rock structures by replacing them with wood structures. Due to the transparent and successful partnership between Ecotone and the design team, the changes were made without causing any delay in the construction timeline. Moreover, Ecotone was able to manage critical logistics challenges, which included limited access and maneuvering around utilities, in order to complete construction in May 2016.
