Staff Recommendation
APPROVE variances 1-4 because the existing access strip and site conditions restrict compliance with the Subdivision Regulations, and the proposed variances will not create a traffic hazard.

APPROVE the Concept Plan subject to 11 conditions:

1. Connection to sanitary sewer and meeting any other relevant requirements of the utility provider.
2. Provision of a street name which is consistent with the Uniform Street Naming and Addressing System within Knox County (Ord. 91-1-102).
3. Widening Carpenter Rd. from the subdivision entrance south to the entrance for Carpenter Ridge Subdivision, to a width of 18' as required by the Knox County Department of Engineering and Public Works. Design plans for the road widening shall be submitted to the Knox County Department of Engineering and Public Works at the design plan stage of the subdivision with the improvements being made in conjunction with the road improvements for the subdivision.
4. Prior to the issuance of any grading permits for the subdivision and prior to submission of a final plat, the applicant shall establish at least 300' of sight distance in both directions along Carpenter Rd. at the subdivision entrance. The required sight distance shall be certified in the field. (See comment section below)
5. Obtaining off-site grading easements if needed for the construction of Road A from Carpenter Rd. west to the first lots for the Subdivision.
6. Installation of sidewalks as identified on the concept plan. Sidewalks shall meet all applicable requirements of the Americans with Disabilities Act and the Knox County Department of Engineering and Public Works. A bond shall be provided to the Knox County Department of Engineering and Public Works by the developer in an amount sufficient to guarantee the installation of the sidewalks.
7. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.
8. Obtaining a determination from the Tennessee Department of Environment and Conservation (TDEC) on whether the closed contour in the vicinity of Lots 31-38 and 67-70 is a sinkhole. If the feature is a sinkhole, the concept plan would have to be modified, subject to staff approval, to create lots with adequate building sites outside of closed contour and associated drainage easement. A 50' building setback from the closed contour shall also be shown on the concept plan and final plat. Building 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. The geotechnical study must be completed and submitted to Knox County Department of Engineering and Public Works prior to submission of the final plat for any lots that do not have a building area outside of the 50' setback area. A 5' drainage easement extending outside of the uppermost closed contour is required. Building construction is not permitted within the hatchered contour area of the sinkhole or the drainage easement. Engineered footings may be required for any structures within the 50' sinkhole buffer.
9. Prior to certification of the final plat for the subdivision, establishing a property owners association that will be responsible for maintenance of the common area, any amenities and the drainage system.
10. Any requests for further subdivision of the property above the proposed 70 lots will require the submission and approval of a traffic impact study and implementation of any required street improvements.
11. Submitting to Planning staff prior to final plat review by the Planning Commission or Planning staff, the certification of design plan approval form as required by the Knoxville-Knox County Subdivision Regulations.
Disposition Summary
APPROVE variances 1-4 because the existing access strip and site conditions restrict compliance with the Subdivision Regulations, and the proposed variances will not create a traffic hazard.
