CHANGES TO STAFF REPORT 6/5/2023

A variance to the Subdivision Regulations was added. This is to reduce the tangent length between broken back curves from 150 ft to 65 ft. There are two slight curves in the road and the reduced tangent length will not create a traffic hazard.

Condition #8 was added to require Shannon Lane to be widened to 18 ft. The portion to widen will be determined during permitting, but will include the southern portion near the development where the road narrows to approximately 12 to 13 ft.

****************************************
This request is for up to 8 residential lots on 4.321 acres zoned RN-1 (Single-Family Residential Neighborhood) and a 235-ft extension of Shannon Lane. The minimum lot size and width in the RN-1 zone is 10,000 sqft and 75-ft wide. The proposed lots range in size from 12,797 sqft to 23,039 sqft.

Shannon Lane is a dead-end street with 14 ft to 16 ft in pavement width. There are currently 12 lots (11 houses, including the 1 on the subject lot) that access Shannon Lane. When the subdivision was originally platted in 1940, there were twelve (12) new 100-ft lots created, with 10 of the lots being on the west side of the street. There were also two existing homes on the north side of Shannon Lane, one of which is the existing house on the subject property. Two additional lots were created on the east side of Shannon Lane in 1974. These lots are also 100-ft wide. The Shannon Lane right-of-way originally extended to the southern boundary of the subject property but was closed by the County before this area was annexed into the City.

Three (3) of the original lots are on the subject property but were never developed. These 3 lots still exist but are under a single ownership, showing as one parcel with the house on the subject property. These 3 lots are being resubdivided into four (4) 75-ft lots on the west side of the Shannon Lane extension. The parcel with the existing house located on the north side of the Shannon Lane extension will also be subdivided into 4 lots.

The City of Knoxville Department of Engineering has the authority to approved reduced right-of-way and pavement widths for public streets. The proposal meets the minimum standards standards in the subdivions regulations; 50-ft right-of-way, 26-ft pavement, and curbing. The existing Shannon Lane has a 40-ft right-of-way, 14-ft to 16-ft of pavement, and no curbing. If the Engineering department deems that it is appropriate for the extension of Shannon Lane to have a cross section that is more in keeping with the existing Shannon Lane, they can approve an alternative design during the design plan phase.
