Re:
PROJECT NAME
Disapproval of Request for Stream Exemption
Project Location
Town Name, North Carolina
Dear Applicant Name:
Please be advised that the Request for Stream Exemption that you submitted for
PROJECT NAME has been disapproved by this Office. Charlotte-Mecklenburg Storm
Water Services staff have performed an on-site evaluation using the North Carolina
Division of Water Quality (NCDWQ) methodology for stream identification and
determined that the stream reach as shown on the attached aerial photograph is an
intermittent stream or a perennial stream (see attached form). This stream reach will be
subject to the applicable Post Construction buffer requirements when development or
redevelopment activities occur on the property.
The Planning Department for the TOWN NAME is being notified of this disapproval by
copy of this letter.
If you have any questions or want to discuss the evaluation, please call Inspector Name at
