Details of Action

+
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. Widening Carpenter Rd. from the subdivision entrance south to the entrance for Carpenter Ridge Subdivision, to a design standard acceptable to 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 at the subdivision entrance onto Carpenter Rd. 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. (Condition deleted by MPC)
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 32-38 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. 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.
