Subject: City of Charlotte
Charlotte Water Intake
Shoreline Stabilization Application
Gentlemen:
1906.013-4
The City of Charlotte owns a property on Torrence Chapel Road in Cornelius, North Carolina for
which Charlotte Water maintains a Water Intake Structure on Lake Norman. A portion of the existing
rip rap shoreline along the lake boundary has failed resulting in significant soil erosion. Additional
erosion is imminent if not properly restored. We have met with and reviewed the proposed work
with a representative of Duke Energy Lake Services to ensure the appropriate corrective measures
are incorporated into the work.
On behalf of Charlotte Water, enclosed please find three copies of the following documents for your
review and approval:
• Executed Shoreline Stabilization Application Form (Form: SSGP 10-2013).
• Vicinity Map showing the location of the property.
• Drawing showing the proposed Shoreline Stabilization.
• Photographs of the existing rip rap shoreline and impacted area.
A check in the amount of $240 is also enclosed for the Application Fee.
Should you have any questions or need additional information, please feel free to call me at
704.338.4662 or email me at [e-mail].
Yours very truly,
WILLIS ENGINEERS
