McAdams conducted a stream condition assessment and provided a feasibility report in the summer of 2015 to restore an impaired stream for the Town of Knightdale. The impaired stream was highly eroded with a 4-foot localized headcut that has progressed upstream through engineered fill and has exposed a saprolite subgrade layer where the channel incision is most significant. Stream erosion has caused trees located on the stream banks to fall, and is currently threatening the back porch of a local residence. The stream assessment / feasibility report was completed to analyze the current impaired condition of the stream, provide recommendations for stabilizing and / or restoring the stream, and develop a strategy to mitigate future property damage. Three recommendations were presented within the feasibility report. Option 1 provided cost-effective repairs to the channel in its current location through stabilization techniques. Option 2 provided instream restoration using natural channel design techniques to create a more permanent and less maintenance-intensive solution. Option 3 provided stream restoration by moving the stream back into the public drainage easement and proposing a new adequately sized channel with appropriate stabilization. McAdams is now in the design phase of the stream repair project.

 

From the initial information gathering phase to the completion of the reports, McAdams always took the time to understand the issues at hand, carefully analyze them and explain the potential solutions in a manner that I could convey easily to others.
