Staff Recommendation

APPROVE variances 1-6 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 for up to 56 residential lots subject to 15 conditions:

---

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. Prior to final plat approval, the right-of-way for the Schaad Rd. extension shall be dedicated so that a public street connection will be established between the existing Olive Branch Ln. and Ivy Bridge Ln. in the proposed subdivision.
4. Identifying the slope easement for the Schaad Rd. extension on the final plat. If the final plat is to be recorded prior to the completion of the Schaad Rd. extension, the temporary construction easement shall also be shown on the plat.
5. At the time of design plan submittal, provide cross sections at 50? intervals that show how the sidewalks and driveways tie in.
6. At the time of the design plan submittal, provide a geotechnical report that includes the retaining wall design.
7. Provide a 50? buffer on Grassy Creek (measured from top of bank).
8. Provide a 50? buffer on each side of the blue-line stream on the east end of the property. Please note that the inner 25? cannot be disturbed with the grading as currently shown on the revised concept plan.
9. Presenting design plans for the storm drainage system to the Knox County Department of Engineering and Public Works indicating how the subdivision's storm drainage system will be integrated with the storm drainage for the Schaad Rd. extension project.
10. Planting a landscape screen, that at a minimum will be a single row of evergreen trees on 10' centers with branches touching the ground (installed height of 8' and a mature height of 30'), along the north side of the slope easement for the Schaad Rd. extension for lots 1-4 and 45-56 in order to reduce the impact of the proposed arterial road on the adjoining lots. This landscape screen shall be planted upon the completion of the Schaad Rd. extension in this area, when the temporary construction easement is no longer needed. The landscape screen may be planted in the slope easement area, only if approved by the Knox County Department of Engineering and Public Works.
11. The grading limits line shown on the concept plan shall be designated on the final plat as a "no clearing/grading limits" line with a notation on the plat that no clearing or grading will be allowed on the north side of the line during the construction of the subdivision and individual homes. Slight adjustment to this line may be approved by both the County Engineering and Planning Commission Staff based on more detailed grading plans. The no clearing and grading line shall be clearly marked in the field before any further grading is done on site.
12. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.
13. Placing a note on the final plat that all lots will have access only to the internal street system.
14. A final plat application based on this concept plan will not be accepted for review by the MPC until certification of design plan approval for the revised concept plan has been submitted to the MPC staff.
