1. Connection to sanitary sewer and meeting any other relevant requirements of the Knox County Health Department.
2. Provision of street names which are consistent with the Uniform Street Naming and Addressing System within Knox County (County Ord. 91-1-102).
3. Conducting compaction testing in all fill areas associated with street construction and building sites per the requirements of the Knox County Department of Engineering and Public Works.
4. Placing a note on the final plat that all structures will have to be located at least 50' from the top of the sinkhole (closed contour area) on this site, as determined by the Tennessee Department of Environment and Conservation. Construction within the 50' setback may be permitted if a geotechnical study prepared by a registered engineer states that building within the 50' sinkhole buffer is acceptable and the study is approved by the Knox County Department of Engineering and Public Works. Engineered footings are required for any structures within the 50' sinkhole buffer.
5. Meeting all applicable requirements and obtaining all required permits from the Tennessee Department of Environment and Conservation for any alteration to the sinkhole.
6. Identifying the floodway, no-fill, 100 and 500 year flood fringe boundaries and the required minimum floor elevations (MFE) for all applicable lots on the final plat.
7. Prior to obtaining Design Plan approval, submitting detailed plans for the creek crossing, revising the flood study to show that the proposed design of the creek crossing will comply with the Knox County Storm Water Ordinance, and obtaining approval from the Tennessee Department of Environment and Conservation for the crossing and any alteration.
8. Prior to obtaining Design Plan approval, submitting a detailed grading plan for the street and lots on the southeast side of Hickory Creek in order to determine that all lots are accessible and contain an adequate building site.
9. Prior to design plan approval, the applicant's surveyor or engineer shall provide documentation acceptable to the Knox County Department of Engineering and Public Works that there is 400 feet of sight distance in both directions along Yarnell Rd. at Planters Ln. pursuant to the requirements of the Minimum Subdivision Regulations. The applicant's surveyor shall also certify the 400 feet of sight distance on the final plat and record any sight distance easements that may be determined to be necessary by the Knox County Department of Engineering and Public Works.
10. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.
11. Prior to design plan approval, providing documentation to MPC and Knox County Department of Engineering and Public Works Staff, that the owners of those lots that are presently served by the Joint Permanent Easement (JPE) located along the eastern boundary of the site have agreed to the revised access. The revised JPE and maintenance agreement shall be recorded with the final plat.
12. As a part of design plan review, submit plans for providing safe ingress and egress for the residents of the four lots presently served by the JPE during the construction phase of the new entrance road.
13. Placing a note on the final plat that all lots will have access only to the internal street system.
14. Meeting all requirements of the approved Use-on-Review development plan.
15. A final plat application based on this concept plan will not be accepted for review by the MPC until certification of design plan approval has been submitted to the MPC staff.

Staff Recommendation

APPROVE variances 1 and 2 because the site's topography restricts compliance with the Subdivision Regulations, and the proposed variances will not create a traffic hazard.

APPROVE the concept plan subject to 15 conditions
