1) Connection to sanitary sewer and meeting other relevant utility provider requirements.
2) Provision of street names consistent with the Uniform Street Naming and Addressing System within Knox County (County Ord. 91-1-102).
3) Implementing the recommendations of the Maynardville Pike Subdivision Transportation Impact Study (TIS) by AJAX Engineering, 5/15/2024, as revised and approved by Planning, Knox County Engineering and Public Works, and the Tennessee Department of Transportation (TDOT) staff (see Exhibit B). A Memorandum of Understanding with Knox County Engineering and Public Works for completing off-site improvements may be required per Chapter 54, Article V of the Knox County Code (Ord. O-23-4-102).
4) Providing sight distance easements through the horizontal curve radius less than 250 ft per the requirements of Knox County Engineering and Public Works during the design plan phase. Any driveways that cannot be located outside the sight distance easement must have a 20 ft depth outside the sight distance easement.
5) Providing a sidewalk on one side of Road 'A' per the requirements of the Knox County Sidewalk Ordinance (Chapter 54, Article IV of the Knox County Code).
6) Providing an engineer report of the culvert over the Mill Branch stream per the requirements of Knox County Engineering and Public Works during the design plan phase. It is the property owner's responsibility to bring any structural deficiencies of the culvert into compliance with Knox County's standards for public streets.
7) Submitting a geotechnical report of the closed contour on the site to be reviewed and approved by Knox County Engineering and Public Works during the design plan phase. If it is not a sinkhole, the certification to be provided by Knox County Engineering and Public Works must be placed on the final plat. If it is a sinkhole, the area shown as a closed contour must be shown on the final plat with a 50-ft buffer as required by Section 3.06.B. of the Subdivision Regulations. If any building construction is proposed within the 50-ft buffer area around the designated sinkholes/depressions (including the depressions), a geotechnical report must be prepared by a registered engineer to determine soil stability and that report must be submitted to the Knox County Department of Engineering and Public Works for consideration. Any construction in these areas is subject to approval by the County following a review of the report. Engineered footings must be designed for these areas. For those lots that do not have a building site outside of the 50-ft buffer, approval by Knox County will be required prior to final plat approval. The sinkholes/depressions and 50-ft buffer shall be designated on the final plat even if they are approved to be filled. Lots that do not have buildable areas outside the sinkholes/depressions shall be combined with other lots to establish a buildable area.
8) Providing the right-of-way stub-out at the western terminus of Road 'A' and notification of future connection per section 3.04.C.2 of the Subdivision Regulations. The curb radii and pavement shall be installed as shown in the concept plan.
9) Access to the detention pond located behind Lot 102 must be approved by Knox County Engineering and Public Works during the design plan phase.
10) Meeting all applicable requirements of the Knox County Zoning Ordinance, including but not limited to the driveway corner clearance spacing requirements of Article 3, Section 3.51.02.C. of the Knox County Zoning Ordinance.
11) Meeting all applicable requirements of the Knox County Department of Engineering and Public Works and TDOT.
12) Before certification of the final plat for the subdivision, establish a property owners association or other legal entity responsible for maintaining common facilities, such as common areas, amenities, private roads, and/or stormwater drainage systems Concept Plan conditions
