Dear Ms. Higgins:
Thank you for your letter dated February 22, 2013 requesting additional information regarding the

your letter.
1. Provide documentation from an appropriate mitigation bank indicating willingness to
accept your request to purchase 195 linear feet of stream credits.

the City of Charlotte Umbrella Stream and Wetland Mitigation Bank ( "Umbrella Bank "). A
letter of acceptance from the Umbrella Bank is attached.
2. Provide a monitoring plan for the stream enhancement and stream relocation portions of
the project.
A monitoring plan has been prepared for the enhanced and relocated stream reaches.

Stream Mitigation Guidelines for North Carolina. A copy of the Stream Enhancement
Monitoring Plan is attached.

Provide a schedule for the work including measures that will be taken to ensure that all
work in or adjacent to stream waters is conducted so that the flowing stream does not

All channel work shall be conducted in the dry. Coffer dams and rock check dams shall be
used to create a pump around so as to prevent flowing water from contacting work areas. An
erosion control plan is included in the plan set for the project. Sheet EC -3 of the erosion
control plan gives details of the proposed pump around. Copies of the erosion control plan
