Re: Horsepen Creek Mitigation Areas 1, 2, and 3
Piedmont Triad International Airport
Year 1 and 2 Site Visit
NC-DWQ # 20000846
Dear. Mr. Brame:
Michael F. Easley, Governor
William G. Ross Jr., Secretary
North Carolina Department of Environment and Natural Resources
Colleen H. Sullins, Director
Division of Water Quality
Tammy Hill from the Division of Water Quality (DWQ) 401 Oversight and Express Review Permitting
Unit conducted a site visit at the above-mentioned mitigation site on May 2, 2007. Several areas
needing repair work were noted during the visit:
Wetland Restoration
• Multiple areas with low vegetation density due to flooding, excessive wetness, or competition
from undesirable species (e.g. cattail) that had been removed were observed. Representatives
from ECS and Baker indicated that replanting of these areas would occur as soon as practicable
during weather conditions that would support establishment of new vegetation.
• One area of erosion due to upland runoff was noted and would need to be repaired.
Stream Restoration
Several stream sections, especially in meander bends, were experiencing erosion due to heavy
flows. Representatives from ECS and Baker indicated that these sections were scheduled for
repair and reinforcement.
• The upstream end of the restored stream reach demonstrated bank erosion that had created a deep
pool. Representatives from ECS and Baker indicated that the pool appeared to have stabilized,
therefore no repair work was scheduled for this monitoring year.

We look forward to receiving written details of the repair work conducted this year at Horsepen Creek.
Since the site is still early in its monitoring period, this information may be included with the next
annual monitoring report. Please note that issues requiring remedial work at a mitigation site may reset
the five-year monitoring clock. This determination will be made at a future time, once data from future
monitoring reports is evaluated. We appreciate the attention that both ECS and Baker are paying to this
site, and we look forward to working with you toward its success over the next few years.
Please feel free to contact Eric Kulz or Tammy Hill at [phone] if you have any questions
regarding this project.
Sincerely,
Cyndi B. Karoly, Program Manager
