401 Compliance Inspection
DWQ# 07-1778V2
Mecklenburg County
Dear Ms. Cook:
October 20, 2010
On October 19, 2010, a compliance inspection was conducted at the subject site. The following concerns
were noted and need to be addressed to close out the project:
Stream S1: The bank on the upstream end of the culvert needs stabilization. The current state of the bank
may threaten the stability of the trail. In establishing the bank, coir fiber logs (not rip rap) should be utilized.
These will provide the required short term stability for vegetation establishment, but over time will degrade.
Some minor work is required at the gabion basket on the downstream end of the culvert
Stream S2: Remove the matting up and down stream of the culvert in the stream bed.
Stream S3: On the upstream end of the crossing, establish a base flow channel to the center culvert.
Remove the matting for this segment from the channel. Construct benches on each side of the center
culvert.
Stream S4: Construct benches on both up and downstream end of the culvert. Some minor shaping of the
bank is required due to the placement of the culverts to allow free flow of water during storm events.
Once the work has been completed you may submit photos of the work. If you have any question please
contact me at 704-663-1699.
Sincerely,
Alan D Joh o
