2) Provision of street names consistent with the Uniform Street Naming and Addressing System within Knox County (County Ord. 91-1-102).
3) Providing sight distance easements 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 driveways that cannot be located outside the sight distance easement must have a 20 ft depth outside the sight distance easement.
4) Providing shared driveways for the lots that access Harvey Road, as shown on the concept plan.
5) Providing a vehicle turnaround for all driveways access points to Harvey Road.
6) On the final plat, the area south of Lot 26 must be either incorporated into Lot 26 or labeled as a common area.
7) 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 into an 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.

This proposal is for a 26-lot detached residential subdivision on 13.42 acres at a density of 1.9 du/ac. In June 2024 (5-L-24-RZ), the property was rezoned from A (Agricultural) to PR (Planned Residential) up to 2 du/ac. Nine (9) lots use Harvey Road as frontage, with every other lot sharing an access point. The remaining 17 lots access an extension of Crescent Oaks Lane, which was constructed with The Oaks subdivision. The right-of-way of Crescent Oaks Lane was extended to the subject property with the intention of being extended in the future. If the road were not intended to be extended, a cul-de-sac would have been required at the end of the road. The proposed lots have a similar width and size as those in The Oaks subdivision.

ALTERNATIVE DESIGN STANDARDS
The applicant is requesting to reduce the minimum horizontal curve radius from 250 ft to 125 ft. The reduced radius helps to reduce grading towards the stream and reduces vehicle speeds. A sight distance easement is required on the inside of the curve through an area that is not a building lot.
