The morning started with a general discussion of the site including an overview of the conceptual plan
and locations of on-site jurisdictional channels and ditches. Daniel and Charlie broke off to discuss
vegetation issues including pre-construction management as well as long-term issues including the
plantings, monitoring success criteria, and invasive species management.
Reach 131- Primary approach for this perennial reach will be full buffer restoration.
- Briefly discussed plans for relocation of the existing culvert crossings.
- Jurisdiction of B1 was determined to be perennial.
- Sue expressed no issues with claiming proposed restoration on the majority of the reach
due to a prevalence of invasive vine and shrub species and no trees.
- Sue requested a more detailed stem count on the lower portion of this reach (approximately
200 LF) as well as a map showing the stem count plot. This portion of the reach exhibits a
larger number of small trees.
- Matt agreed to check the buffer mitigation language with regard to trees of 5" DBH or
greater with regard to "enhancement" or "restoration" credit.
Reach 132- Primary approach for this ditched intermittent reach will be full buffer restoration.
- Examined upstream,forested conditions of intermittent stream.
- Upon further review of the Randleman buffer rules, Sue determined that since this system is
defined as a modified natural stream, it is subject to the buffer rules and will qualify as
mitigation.
Reach 133- Primary approach for this ditched, intermittent reach will be full buffer restoration.
- The headcut at the upstream portion of this reach was located and flagged. It was
determined that this would be the start of the proposed buffer. Matt will GPS this location
on a future site visit(see attached map).
- The previously proposed ephemeral portions of this reach were determined to not qualify
for buffer mitigation due to a lack of any channel form.
- Sue and John discussed the existing storm water basin along the new NC-311 corridor
located upstream of the northern ephemeral reach. Sue stated that she would review the
storm water plan for NC-311 to ensure that a diffuse flow is planned for this area.
Reach Al- Primary approach for this intermittent/perennial reach will be full buffer restoration.
- Sue requested a more detailed stem count along the middle portion of this reach due to the
presence of several mature trees along the right bank.
- No other issues arose for this reach.

Reach A2- Primary approach for this intermittent and ephemeral system will be full buffer restoration.
- John and Sue discussed the issue of direct, untreated, storm water flows from the dairy to
these upstream ephemeral reaches and the positive impacts from buffering these locations.
- The upstream ephemeral break and intermittent break were defined and flagged. Matt will
GPS these locations on a future site visit.
- Sue requested an additional stem count and plot location along this reach.
- Based on additional discussions between EEP and DWQ, it was determined that DWQ is
going to continue to interpret the revised Randleman rules as the old rules with regard to
ephemeral ditches. These features will qualify for buffer mitigation as long as a truly formed
ditch/channel is present as opposed to a swale or dip in the landscape.
Meeting adjourned approximately 11:00am.
