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. 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. An agreement between the two property owners is required for the pond to be off-site of the development.
4. If during design plan approval or construction of the development, it is discovered that unforeseen off-site improvements within the right-of-way are necessary as caused by the development, the developer will either enter into a memorandum of understanding (MOU) with the County for these improvements or reimburse the County for their direct expenses (if completed by County crews) to make corrections deemed necessary.
5. Land disturbance within the HP area shall not exceed 10.99 acres, as recommended by the slope analysis (attached). The limit of disturbance is to be verified and delineated on the site with high-visibility fencing before grading permits are issued for the site.
6. Meeting all applicable requirements of the Knox County zoning ordinance, including the 30 ft non disturbance buffer around the perimeter of the property except along Hill Rd frontage. Selective tree removal is permissible for the removal of invasive species or to alleviate safety hazards, such as trees that are falling, dead, or dying. The limit of disturbance is to be verified and delineated on the site with high-visibility fencing before grading permits are issued for the site. The 30 ft non disturbance buffer should be drawn and noted in the plat.
7. Meeting all applicable requirements of the Knox County Department of Engineering and Public Works.

The applicant is requesting approval of a 50-lot single family subdivision in Halls. The development is on Hill Road, and the entrance will align with the subdivision entrance across the street. The internal roads will be public streets 26 ft wide within 50-ft right-of-way. While stormwater detention and the rear of Lots 1-17 are shown within the 150-ft TVA easement along the western property boundary, no structures can be located within the easement.

Most of the property is within the HP (Hillside Protection) area. The preliminary grading plan shows that the HP disturbance on the site is 8.4 acres, which doesn't include the disturbance of creating access to the stormwater pond. The slope analysis recommends a disturbance of 10.99 acres. There is a condition that the disturbance budget not be exceeded.
