Deitrick Road Outfall Restoration (ITB)

The Work consists of an outfall restoration for the site which will include an existing and restored reach length of 160 LF. The restoration will utilize Natural Channel Design (NCD) techniques, the channel will be restored by utilizing priority level 2, raising the stream bed slightly and creating a bankfull bench within the confined valley. The banks along the floodplain of the confined channel will be graded back allowing for 2:1 slopes, creating greater stability. A B4a channel has been designed for the site with a steeper step pool sequence connecting upstream and downstream culvert elevations. Step and pool cross sections were developed using a combination of Virginia regional curve data, reference reaches, and onsite bankfull data collection.
