Disposition Summary

Approve the variance to reduce the broken back curve tangent from 150' to 88' Road A Sta 6+18.
A. The property has steep topography in this location.
B. The lots have been clustered in the buildable areas to minimize disturbance in the Hillside Protection Area.
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.

Approve the variance to reduce the broken back curve tangent from 150' to 63' Road B Sta 3+80.
A. The property has steep topography in this location.
B. The lots have been clustered in the buildable areas to minimize disturbance in the Hillside Protection Area.
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.

Approve the variance to reduce vertical curve length on Road A from K=25 to K=16 at sta 8+51.91, based on the following evidence of hardship.
A. Due to the existing steeper topography along this section of Road A, a reduction of the vertical curve length is needed.
B. The existing slope is steep, and the variance allows for a smoother approach.
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. Knox County EPW recommends approval of this variance based on the justifications provided by the applicant.

Approve the variance to reduce vertical curve length on Road B from K=25 to K=18 at sta 3+15.89, based on the following evidence of hardship.
A. The steep topography throughout the property requires reducing the vertical curve length to keep site grading balanced.
B. The location and grade of the existing access easement presents a unique challenge.
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. Knox County EPW recommends approval of this variance based on the justifications provided by the applicant.

Approve the concept plan, subject to 9 conditions.

1. Connecting to sanitary sewer and meeting other relevant utility provider requirements.
2. Providing 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. Before recording the final plat for the subdivision, establishing 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.
5. Providing a sight distance easement through the horizontal curve radius less than 250 ft and, if necessary, through Lot 17 to maintain 250 ft of sight through the curve on Road B, per the requirements of Knox County Engineering and Public Works during the design plan phase. Any driveways that cannot be located outside the sight distance easement must have a 20 ft depth outside the sight distance easement.
6. Providing a stream determination study to the Knox County Department of Engineering and Public Works for review and approval regarding a potential stream through Lot 17, Lot 4 and under Road B. The required stream buffers must be provided if this is determined to be a stream.
7. The access easement must run through at least one lot and cannot be platted separately from the lot.
8. Meet all applicable requirements of the Knox County Zoning Ordinance.
9. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.

The most recent approval on this property was in 2000 for 34 lots (3-SE-00-C). This proposal is for 35 single-family lots on 20.38 acres. The property is zoned RA (Low Density Residential). The RA zone requires a minimum lot size of 10,000 sq ft. The proposed lots are 10,218 sq ft to 121,268 sq ft and are generally equivalent to the lot sizes in the area.

Two new public roads will be built off Mountie Ln in the Eastwood Estate subdivision, and an access easement will be created at the rear of the property for the large lots. Because of the steep topography, the pavement width of the public roads has been reduced to 22 ft from 26 ft, and the right-of-way width has been reduced to 40 ft.

The total Hillside Protection Area is 19.56 acres. The preliminary grading plan shows 8.72 acres of disturbed area, which doesn't include the houses off the access easement. The slope analysis recommends a disturbance budget of 6.88 acres.
