Brad,
I had promised you some answers this week, so here is where we stand:
1. 1 sent the CE document to you by e-mail previously.
2. The DMS acceptance letter is dated March 9, and accepts 0.280 acre of riparian impacts
(attached). The actual number will go down a bit since we have switched some of the
mechanized land clearing has switched to handclearing. We can revise the acceptance later.
3. The drawings have been changed to put handclearing outside of the detour instead of
mechanized.
4. Sheet 5 is in the new package. (attached)
5. Division 2 has indicated that the slope of the temporary detour will be wrapped with
geotextile fabric to aid in restoring the area back to preexisting elevations. A reforestation
detail sheet has been prepared by our mitigation and monitoring group (attached), and the
site can be monitored for 2 years if desired.
6. We have learned that an estimated 0.03 Ac of Temporary Fill will be needed in the Hand
Clearing areas for Erosion Control measures.
I will be adding all of this info to the online PCN once I figure out how to supplement one through
that system.
Have a nice weekend, everyone!

Chris/Gordon,

The application has been received and reviewed and found to be incomplete for processing. I have
discussed the project with DWR and we request the following information to continue processing:
• In order to utilize NW 23 we will need to confirm that the impacts requested are contained
within the CE document. Please include the CE on your re submittal.
• Please include the mitigation reservation letter from NC DMS.
• The current plan calls for permanent impacts (MC) bordering the temporary impacts. Typically
temporary impacts are bordered by temporary impacts (HC). Please either change this or
explain why additional avoidance can't be realized.
• Permit drawing 10 of 15 has a match line on the left side of the page to sheet 5. Sheet 5 is not
in the package please provide this sheet so that impacts can be confirmed absent or present.
• Finally, the temporary fill in wetlands is greater than 0.25 of an acre. Please further explain
how this temporary impact will be constructed and what steps will take place to avoid
permanent impacts such as compaction. Also further explain the restoration activities
anticipated upon project completion to include how will successful restoration be judged.
With this amount of impact will at minimum a couple years of monitoring be appropriate?
If you have any questions about this email please don't hesitate to give me a call.
Thanks,
Brad
