Disposition Summary
Approved with Conditions
Approve the variance to reduce the K value from 25 to 14.29 at sta Road A from sta 0+37 to 2+11.
A. Due to the existing steeper topography along Road A, a reduction of the vertical curve length is needed to keep site grading balanced.
B. The topography and shape of the property are unique and have not been created by any person having an interest in the property.
C. This is a road with low traffic volumes, and the variation is not great enough to cause detriment to public safety, health, or welfare, nor would it be injurious to other properties in the neighborhood. Knox County EPW recommends approval of this variance based on the justifications provided by the applicant.

Approve the Concept Plan subject to 10 conditions.
1. Connection to sanitary sewer and meeting other relevant utility provider requirements.
2. Provision of street names consistent with the Uniform Street Naming and Addressing System within Knox County (County Ord. 91-1-102).
3. If during design plan approval or construction of the development, it is discovered that unforeseen off-site improvements within the right-of-way are necessary as caused by the development, the developer will either enter into a memorandum of understanding (MOU) with the County for these improvements or reimburse the County for their direct expenses (if completed by County crews) to make corrections deemed necessary.
4. Providing a sight distance easement through the horizontal curve radius less than 250 ft per the requirements of Knox County Engineering and Public Works during the design plan phase. Any driveway that cannot be located outside the sight distance easement must have a 20-ft depth outside the sight distance easement.
5. Providing a stream determination study to the Knox County Department of Engineering and Public Works for review and approval during the design plan phase regarding the potential stream.
