This proposal is for a residential subdivision with 135 residential dwellings on individual lots, comprising 130 attached and 5 detached houses, on approximately 38 acres. The proposed density is 3.55 du/ac. The property was rezoned from A (Agricultural) to PR (Planned Residential) up to 4 du/ac in August 2023 (7-Q-23-RZ). The two existing houses along Millertown Pike will remain and three large lots for detached houses are located on the south side of the stream on the southern portion of the property.

TRANSPORTATION IMPACT STUDY (TIS)
The submitted TIS concludes that turn lanes on Millertown Pike are not warranted and that a single exit lane is sufficient (see Exhibit A). The study also recommends that Knox County should consider modifying the beginning location of the westbound passing zone on Millertown Pike so it starts a minimum of 100 ft away from the centerline of the proposed entrance road. The passing zone currently starts 50 ft from the proposed entrance road.

VARIANCES AND ALTERNATIVES DESIGN STANDARDS
Variances: The concept plan was revised on 10/3/2023 to not require a variance.

Alternative Design Standard #1: This request is to reduce the minimum 25 ft lot frontage for residential lots to 22 ft for interior lots of grouping of attached houses and to 20 ft for the lots on the Road 2 bulb. Section 3.03.B.1. of the Subdivision Regulations allows the Planning Commission to reduce the minimum street frontage to 20 ft for attached house lots if guest parking is provided throughout the development. Guest parking is provided on Road 1 and Road 2.

Alternative Design Standard #2: The request is to reduce the minimum horizontal curve from 250 ft to 150 ft on Road 1. The inside of this curve does not have houses, so the sight distance through this curve will remain open. A sight distance easement of 200 ft is required through the curve.
