Staff Recommendation

APPROVE the concept plan subject to 11 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 (City Ord. 0-280-90).
3. Installation of sidewalks on at least one side of both Roads A & B. Sidewalks shall meet all applicable requirements of the Americans with Disabilities Act (ADA) and the Knoxville Department of Engineering. A bond shall be provided to the Knoxville Department of Engineering by the developer in an amount sufficient to guarantee the installation of the sidewalks.
4. The closed contour/sinkhole and the 50' setback around the feature shall be shown on the 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 Knoxville Department of Engineering. The geotechnical study must be completed and submitted to the Knoxville Department of Engineering prior to submission of the final plat for any lots that do not have a building area outside of the 50' setback area. Building construction is not permitted within the hatchered contour area of the sinkhole or required drainage easement. Engineered footings may be required for any structures within the 50' sinkhole buffer.
5. Based on the recommendations from the report submitted by Cultural Resource Analysts, Inc. and dated October 31, 2016 (copy enclosed in MPC package), Staff recommends the following: a) A 25' buffer be established along the north and east side of the cemetery fence line for Mars Hill Cemetery. The portion of the buffer that is outside of the cemetery parcel shall be included in a common area parcel for this subdivision. The common area would also include at a minimum, a 25' wide access strip/easement for the cemetery out to the public right-of-way of Road A. A paved driveway to the cemetery parcel shall be installed meeting the requirements of the Knoxville Department of Engineering. b) Following design plan approval and prior to the submission of the final plat to the Planning Commission for review, conducting a preliminary site grading/stripping of the property under the supervision of an archaeologist to assure that any unmarked graves on the site are left undisturbed. The preliminary site grading/stripping investigation area shall include the proposed right-of-way for Road A and all of proposed Lots 2 and 3 (See attached Concept Plan Exhibit A). The timing and details of the preliminary site grading/stripping is subject to the approval of the Knoxville Department of Engineering and MPC staff. c) Submitting a follow-up report on the results of the preliminary site grading/stripping from the archaeologists to MPC staff for review and approval prior to any further site alteration. If any grave sites are discovered, MPC staff will determine if any expansion of the preliminary grading/stripping area is needed, what modifications to the concept plan will be required, and if the concept plan will have to be resubmitted to the Planning Commission for approval.
6. The design of the deceleration lane is subject to the review and approval by the Knoxville Department of Engineering during the design plan stage of the subdivision.
7. Working with the Knoxville Department of Engineering at the design plan stage of the subdivision on the possible addition of street lighting along Broome Rd. at the proposed subdivision entrance.
8. Meeting all applicable requirements of the Knoxville Department of Engineering.
9. Placing a note on the final plat that all lots will have access only to the internal street system except for the lot created for the existing home site that currently has direct access to Broome Rd.
10. Prior to final plat approval establish a homeowners association for the purpose of assessing and collecting fees for the maintenance of the commonly held assets including the common area, access to the cemetery and the stormwater system.
11. 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.

With the conditions noted, this plan meets the requirements for approval of a concept plan in the R-1E (Low Density Exclusive Residential) District.
