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. Implementing the recommendations of the Carter Ridge Phase IX (n/k/a Carter Valley) Subdivision Transportation Impact Study (AJAX Engineering, 6/1/2026) as required by Knox County Engineering and Public Works during the design plan phase.
5. Widening Carter Mill Road to 20 ft along the full length of the property's frontage, and to 18 ft from the western edge of the property to the McCubbins Road intersection.
6. Entering into a memorandum of understanding (MOU) with Knox County Engineering and Public Works for completing off-site improvements per Chapter 54, Article V of the Knox County Code (Ord. O-23-4-102). The property owner (applicant) shall be responsible for these improvements, except for the final asphalt surface
course, which will be the responsibility of Knox County.
7. Installing sidewalks per Chapter 54, Article IV of the Knox County Code, including but not limited to, the Carter Mill Road frontage and the sections of Road 'N' that exceed 1,000 vehicle trips per day. The location of the required sidewalks will be determined by Knox County Engineering and Public Works during the design
plan phase. Any sidewalks installed that are not required must be maintained by the homeowner's association.
8. Providing a note on the final plat that all lots shall have access from the internal roads only.
9. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.
10. Meeting all applicable requirements of the Knox County Zoning Ordinance.

This subdivision is for 121 detached residential lots on 77.82 acres (1.56 du/ac). The subject property was rezoned from A (Agricultural) to PR (Planned Residential) up to 2.5 du/ac in 2005 (2-C-05-RZ). The subdivision will have one access point to Carter Mill Road.

PEDESTRIAN AND ROAD IMPROVEMENTS
Sidewalks are required along the Carter Mill Road frontage of the property, tying into the existing sidewalk to the east, and for the portion of Road 'N' that exceeds 1,000 vehicle trips per day. The applicant has proposed sidewalks on all internal streets; however, if installed, sidewalks not required by the Knox County sidewalk ordinance must be maintained by the homeowner's association.

Carter Mill Road was widened to 20 ft from the subject property to S Carter School Road by the developer of the Carter Ridge subdivision, who is also the current owner of the subject property. If this application is approved, the substandard portion of Carter Mill Road in front of the subject property needs to be widened to 20 ft, and the remainder of Carter Mill Road to the west must be widened to 18 ft. The applicant must enter into a Memorandum of Understanding with Knox County for the off-site work within the public right-of-way, based upon the costsharing arrangement outlined in Condition # 6.
