Crystal, Kristi and Donna:
Attached you will find a PCN for the 17BP.10.R.13 bridge replacement project in Anson County. The proposed project
would replace an existing timber-decked bridge with a 3 barrel culvert (3 barrels at 7' x 7') on SR 1822 Thomas, or more
accurately, Covington-Thomas Road over N. ForkJones Creek in Anson County.
The design will keep the existing stream width by utilizing a single 7' x 7' barrel as the low-flow barrel. Flood plain
benches will be constructed to restrict flow to the two overflow barrels. It should be noted that the consultant who
prepared the PCN indicated that there would not be an increase in impervious area as a result of this project being
constructed. I am not sure that this is totally accurate but any increase in impervious area would be in the single digits.
We obtained mitigation coverage for 78 linear feet of permanent impacts in 2012 (attached). The length of the
proposed culvert is 63 feet.
Please let me know if you have any questions regarding the attached. Charges may be made to 17BP.10.R.13.
Thank you!
