1. Meeting all 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. Prior to design plan approval, the surveyor will have to certify that a minimum of 300' of sight distance exists and can be maintained at the subdivision entrance onto Buttermilk Rd. in both directions along Buttermilk Rd.
4. Any sight distance easement across adjoining property that would be needed to maintain the minimum sight distance requirements shall be obtained and recorded prior to approval of a final plat for this subdivision.
5. 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) identified on the 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 Lots 41-44 since these lots 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.
6. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.
7. A final plat application based on this concept plan will not be accepted for review by the Planning Commission until certification of design plan approval has been submitted to the Planning Commission staff.
