Staff Recommendation

Approve the requested variances based on the justification provided by the applicant and recommendations of the Knox County Department of Engineering and Public Works.

Approve the Concept Plan subject to 9 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) Installing sidewalks per Chapter 54, Article IV of the Knox County Code, including but not limited to the remaining Carter Mill Road frontage east of the Carter Ridge Road intersection, and internal roads with 1,000 ADT or more. The location of the 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 home owners association.
4) Providing a stream determination study to the Knox County Department of Engineering and Public Works for review and approval regarding a potential stream located in the southern portion of Road C. If this is determined to be a stream, the required stream buffers must be provided, and Road C may have to be shortened and lots consolidated to provide a buildable area outside the stream buffers.
5) If any building construction is proposed within the 50' buffer area around the designated sinkholes/depressions (including the depressions), a geotechnical report must be prepared by a registered engineer to determine soil stability and that report must be submitted to the Knox County Department of Engineering and Public Works for consideration. Any construction in these areas is subject to approval by the County following a review of the report. Engineered footings must be designed for these areas. For those lots that do not have a building site outside of the 50' buffer, approval by Knox County will be required prior to final plat approval. The sinkholes/depressions and 50' buffer shall be designated on the final plat even if they are approved to be filled. If it is determined to be a sinkhole, any lot that does not have a buildable area outside of the designated sinkhole must be eliminated or combined with other lots so it does have a buildable area.
6) The unconstructed portion of Madison Oaks Road in phase 5 of the subdivision must be constructed before the lots in phases 6 & 7 can be platted.
7) Implementing the recommendations of the Carter Ridge Phases VI-VIII Transportation Impact Study (AJAX Engineering, 12/12/2022), as revised and approved by Planning Commission staff and Knox County Engineering and Public Works (see Exhibit A).
8) Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.
9) 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.

The previous approvals for phases 2-5 have 226 lots on approximately 92 acres. Phase 1 of the development is on the north side of Carter Mill Rd. and is in a different PR zone district. There are approximately 75.6 acres remaining in phase 9. The Carter Ridge Subdivision is zone PR up to 2.5 du/ac.

Phases 6 and 7 access Carter Ridge Road at the Madison Oaks Road intersection. Madison Oaks Road provides two additional external access points to Carter Mill Road.

A total of 545 dwelling units is allowed in all phases of this development. If these 3 phases are approved as proposed, approximately 191 dwelling units can be approved in Phase IX, or a combination o new lots in unbuilt portions of other phases.
