401 Certification Application Review
DWQ Project No. 02-1389
Buncombe County
Dear Mr. Riddle:
I have reviewed the application submitted for a 401 Water Quality Certification and have
visited the sites for proposed stream and wetland impacts associated with the development. You
are requesting to fill approximately 1492 linear feet of streams and 0.24 acres of wetlands. Of the
1492 feet of streams you are proposing to mitigate for the stream loss by providing 841 linear feet
of onsite mitigation, 230 linear feet accepted by the Wetlands Restoration Program and 6,488
linear feet of stream preservation.
As you know the Division of Water Quality will only accept up to 10% of the total impacts
for mitigation because preservation does not replace the aquatic life losses. Based on this
review an additional 271 linear feet of stream mitigation are needed to replace the stream losses
associated with this project. However, should you choose to reduce the impacts by avoidance,
then the mitigation requirements would be reduced.
Also, any streams used for mitigation reference reach purposes will need to be approved
by the Division as well as the mitigation plan including the list of trees, shrubs and other
vegetation used for mitigation and plantings in the stormwater ponds.
The information listed above is needed before the Division of Water Quality can issue a
401 Water Quality Certification. Until this information is received and approved, we are placing
this project on hold due to incomplete information in accordance with 15A NCAC 2H :0507 (h)
and are notifying the Corps of Engineers by copy of this letter.
