Description

The project involves restoring a 600 linear feet reach of the Tuckahoe Library stream using natural channel design techniques, including raising the stream bed and creating a bankfull bench. The restoration will stabilize the banks with slopes of 2 to 1 or less and incorporate a steeper step pool sequence downstream. Additionally, sanitary sewer rehabilitation and pipe replacement will be performed to protect the sewer system currently exposed in the degraded stream channel. The site spans multiple parcels in Henrico County and is characterized by a confined valley with significant sediment and erosion issues due to unstable banks and land use changes.
