Subject: University Point Blvd. Extension after-the-fact permit modification
(SAW #: 2012-00145/ DWR #: 15-0646)

Dear Ms. Amschler,

On behalf of Mr. Dan Leaver (City of Charlotte- Engineering and Property Management
Department), I am submitting an after-the-fact permit modification for the University
Pointe Boulevard Extension project (USACE Action ID: 2012-00145/ DWR #: 15-0646).

In March of 2017, I was asked to inspect the aforementioned project for 401/404 permit
compliance on behalf of Mr. Dan Leaver (project manager). At that time, it was
determined that 2 bottomless culverts were potentially out of compliance with the
conditions of the approved permit. At that time, I sought concurrence from both the
USACE and NCDWR on the matter and scheduled field walks with the appropriate
personnel. On March 28, 2017, Crystal Amschler walked the site with Erin Shanaberger
and requested additional time to review the previous submittal prior to providing
feedback. On April 13, 2017, Crystal provided a follow up email summarizing her
thoughts. On May 10, 2017, Erin Shanaberger met Alan Johnson (NCDWR) on site to
discuss the issue. It was determined that additional mitigation should be proposed to
cover impacts that were not accurately represented in the pre-construction notification
provided to both agencies on June 29, 2015. As a result of rock placed along the stream
banks through both bottomless culverts (School Access Road and University Pointe
Blvd), the City of Charlotte is proposing additional mitigation for 189 linear feet (LF) of
impacts at a 0.5:1 ratio for a total of 95 SMUs. The revised total mitigation needed for the
project is 274 SMUs.

On June 9, 2016, Mr. Leaver made a payment to the City of Charlotte Umbrella
Mitigation Bank (City Bank) for 311 SMUs. This was the original proposed mitigation
amount (June 29, 2015); however, it was determined that one stream within the project
area was non-jurisdictional and thus did not require mitigation (see attached permit
approvals). As a result of over-payment to the City Bank, the City Bank will be refunding
Mr. Leaver in the amount of 37 SMUs and the mitigation requirement for the University
Pointe Blvd Extension project has been satisfied.

Enclosed you will find an updated Pre-Construction Notification Form (PCN), prior
permit approvals, updated construction plans and photos of the areas discussed above. If
you have any questions or concerns regarding this project, feel free to contact me at
[phone], or [e-mail] to discuss in more detail.

Sincerely,

Erin Shanaberger
Water Quality Program Specialist
