Contained in this package are documents pertaining to the proposed construction of a new
seawall and retaining wall at the Prewitt residence at 179 Tryon Bay Circle, in Lake Lure,
NC. On May 5, 2013, an eight inch rainstorm occurred over a 1 to 2 hour period that caused
a slope failure on the Prewitt property (Tax Pin 223731) between the back corner of the
house and Lake Lure. The loose soil slid into the Prewitt's boathouse which has since been
removed. There were several large trees that also slid with the sheared layer that were
removed because of safety issues. In order to stabilize the home (which is presently
restricted from access by the county building inspector and fire marshal) a new segmental
block, two tiered wall is necessary to stabilize the property and the home.
By copy of this letter, the Prewitts respectfully request that a 401 Water Quality Certification
be issued for this project. As you can see from the supplied pictures, a prompt review to
facilitate an accelerated construction schedule would be appreciated. The Prewitts are very
anxious to return to their home. If you have any questions or concerns, please contact me at
one of the numbers listed above.
Sincerely,
