Kim

Per our conversation last week, I wanted to provide you with a summary of our plan to complete additional bank repairs
at the Owen Farms Mitigation Site this fall/winter. Erosion is primarily occurring on streambanks that have poor
vegetative coverage. We plan to repair/stabilize approximately 355 LF of stream bank through the use of sod mats and
boulder toe. Standard construction equipment will be used to complete the repairs (i.e. excavator and off-road hauler).
The attached figure depicts the strategy that will be used at each bank repair location. A photo log is also attached that
shows current conditions at each repair location. Sod mats will be collected from on-site within the existing easement.
Areas where sod mats are collected and other areas disturbed during construction will be seeded and replanted. We
estimate needing a total of ~100 sq. yds. of sod mat.

This work will be completed under the existing Nationwide Permit 27 and Erosion Control Permit for the Site. We are
currently coordinating with a construction contractor to determine the repair schedule. Once finalized, we will submit a
written request for a waiver of the trout moratorium from WRC for purposes of completing repair work and minimizing
erosion on-site.

Thank you and please let me know if you have any questions or comments.
