21 <br /> DRIVEWAY LOCATION STUDY <br /> Project Name: Annandale at Creek Wood <br /> Project Number: 12-017 <br /> Report Date: August 31, 2012 <br /> Purpose: The purpose of this report is to determine sight distance conditions based on a <br /> field review and discussions with NCDOT. <br /> SITE DESCRIPTION: <br /> Project Location: 2520 Whitfield Road, <br /> Chapel Hill, NC. <br /> The project is located in Orange County north of Whitfield Road and East of <br /> NC 86. <br /> Site Size: 36.46 acres by survey. <br /> Site Characteristics: The site is a wooded tract bisected by a two streams running from south to <br /> north which converge roughly midway through the site. Thus, three separate <br /> sections of the parcel front Whitfield Road and are available for development. <br /> Existing Access The site was previously a single residential lot with a single driveway <br /> Characteristics: connecting to Whitfield Road. <br /> Sight Distance: Eastward of the current drive, Whitfield Road maintains a <br /> straight section of road that slopes downward from the drive. Sight distance at <br /> this point appears sufficient. Westward of the drive, Whitfield Road curves in a <br /> spiral curve northward, thus creating some sight difficulties in this location at <br /> this time. <br /> Speed: Speeds in this area are posted at 45 mph. As noticed during the <br /> meeting with NCDOT, cars traveling along this route appear to meet or slightly <br /> exceed this speed. Based on observed speeds, Mr. Chuck Edwards (NCDOT) <br /> recommended that sight distances at all proposed entrances be based on 550 <br /> ft. <br /> PROPOSED DEVELOPMENT: <br /> Proposed Usage: The proposed development consists of 11 lots of a minimum of 2 acres in size <br /> with the remainder being placed in open space/buffer area (see attached). <br /> Lots will be accessed via two public roads, one located at the eastern extreme <br /> of the site and another located at the western extreme. The owner proposes <br /> to use curb and gutter at this time. <br /> Proposed Roadway Two roadway connections are proposed onto Whitfield Road and are placed at <br /> Connections: the extremities of the site. The locations of several possible entrances were <br /> investigated in the field with Mr. Chuck Edwards of the NCDOT, resulting in the <br /> following: <br /> Western Entrance: This entrance is located in a straight portion of Whitfield <br /> Road and no concerns were identified. <br /> Drive Locations for Lot 7: Due to its location in the middle of the spiral turn <br /> and the topography in this area, it was agreed that no adequate entrance to <br />
