Disposition Summary

Approve the requested variance to reduce the minimum K value from 25 to 20 between stations 2+45.12 and 4+15.71 Road 'A'.
A. The steep topography through the middle of the property causes a deviation with the vertical curve.
B. The required access from George Light Rd causes the roadway to go through steep topography.
C. The granting of the variance will not be detrimental to public safety, health, or welfare because the shortened vertical curve meets American Association of State Highway and Transportation Officials (AASHTO) standards.

Approve the alternative design standard based on the justifications provided by the applicant and the recommendations of the Knox County Department of Engineering and Public Works.

Approve the Concept Plan subject to 6 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. Before certification of the final plat for the subdivision, establish a property owners association or other legal entity responsible for maintaining common facilities, such as common areas, amenities, private roads, and/or stormwater drainage systems.
4. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.
5. The applicant will widen George Light Rd to 20 ft including the final asphalt surface and striping along the entirety of the property's frontage and south to Beaver Glade Ln prior to recording the plat per the rezoning condition in 7-U-24-RZ.
6. 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, the developer will either enter an (Memorandum of Understanding) MOU with the County for these improvements or reimburse the County for their direct expenses (if competed by County crews) to make corrections deemed necessary.

This is a request for a 33-lot, attached townhome subdivision that will be accessed off of George Light Rd near Pellissippi Parkway.

The front of the property on George Light Rd includes 5.71 acres within the Hillside Protection (HP) Area. The plan proposes to disturb 3.2 acres, which is within the recommended disturbance budget of 3.55 acres as determined by the slope analysis. The steep topography does require a variance to reduce the vertical curve minimum K value from 25 to 20. The granting of the variance will not be detrimental to public safety, health, or welfare because the shortened vertical curve meets AASHTO standards.

A detailed landscape plan has been provided that preserves existing vegetation, and provides landscape buffers between adjacent uses and trees along the entrance road and in parking areas.

Lots less than 25 ft in width require an Alternative Design Standard to be approved by the Planning Commission and must provide guest parking and 20 ft long driveways because street parking is not available. Three parallel guest parking spaces have been provided at the front and 4 spaces at the back of the property in the T-turnaround. The driveways are 20 ft deep and each townhome has a one car garage.
