Subject: RE: [External] Wildlands Pasquotank Umbrella Mitigation Bank -Folly Swamp Site
Kyle, I have reviewed the draft mitigation plan for Folly Swamp. It has been a long time since the site visit for this
project, so I have spent sometime going back through notes and past emails. I have the following comments:
• Although there are circumstances on projects were Priority 2 restoration is necessary it is preferable to limit the
amount of P2 approach due to the limited uplift provided and potential for problems with establishing adequate
vegetation success. In low slope swamp stream systems like the drainages here it is probable the recognized
functional uplift will be even lower with a P2 approach, and approximately 50% of this project is currently
designed as Priority 2 credited at a 1:1 ratio. I believe the IRT should have some additional discussion on this
topic to determine if it's appropriate.
Tributaries Greene, Barker and Morgan have small drainage areas for low slope streams to form flow
paths. Various portions of these channels are shown as head water and P1 intermittent. The sponsor proposed
to install flow gauges to capture 30 consecutive days of flow in this reaches. A) Trail cameras should also be
used to capture this information. WRC would like to see both consecutive and cumulative days captured. B) the
30 day flow requirement is an accepted metric in the Coastal Plain Headwater Wetland guidance, however it is
not intended for use in intermittent streams. Intermittent streams by definition should dry seasonally therefore
exhibiting flow for much longer durations than a headwater wetland. 90 consecutive days of flow for
intermittent reaches would be more desirable to show success.
• The final planting plan should include a more comprehensive list of potential species and percent to be
planted. This list should also include possible alternate species and maximum planting percentage in case
availability is an issue. Along with a detailed description or figure depicting vegetation planting zones i.e.:
planting inside the P2 cut v/s outside, riverine swamp forest v/s headwater wetland, etc.

External email. Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to
Good Morning IRT,
Hope all is well. Wildlands has submitted a Draft Mitigation Plan for the Folly Swam Site. I have
reviewed the information and determined that it is complete for review. Hopefully all of you
received a copy. If not please let me know and I will work with Wildlands to get you one.
Please respond to this email and let me know if you have a copy of the information. Feel free
to contact me if you have any questions.
Thank you.
