April 10, 2025 <br />C. N. (Chuck) Edwards Jr., PE <br />Division 7 - District 1 Engineer <br />North Carolina Department of Transportation <br />PO Box 766 <br />115 East Crescent Square Dr. <br />Graham, NC 27253 <br />(336) 570-6833 <br /> <br />Reference: Rigsbee Subdivision <br /> Orange County, North Carolina <br />Subject: Trip Generation & Turn Lane Warrant Analysis Update <br /> <br />Dear Mr. Edwards: <br />This updated letter provides the trip generation potential for the proposed Rigsbee Subdivision <br />development to be located along NC 54 in Orange County, North Carolina. A letter was previously <br />submitted in February 2025 to the Orange County (County) and the North Carolina Department of <br />Transportation (NCDOT) staff for the proposed development. This updated letter addresses <br />changes to the land use density for the proposed development. <br /> <br />The original letter showed the proposed development would consist of a maximum of 41 single - <br />family detached homes. <br /> <br />This updated letter for the proposed development is assumed to consist of a maximum of 43 single- <br />family detached homes. <br /> <br />Site access is proposed via one (1) full-movement driveway along NC 54. In addition to providing <br />the updated trip generation information for the site, this updated letter summarizes if any turn lane <br />warrants are met at the proposed driveway per the North Carolina Department of Transportation <br />(NCDOT) Policy on Street and Driveway Access to North Carolina Highways (Driveway Manual) <br />Warrant for Left and Right- Turn Lanes nomograph. This updated letter also analyzes traffic <br />conditions with the proposed development built-out during the weekday AM and PM peak hours <br />at the proposed driveway along NC 54. <br /> <br />A copy of the preliminary site plan has been attached for your reference. <br /> <br />Per the North Carolina Department of Transportation (NCDOT) Congestion Management <br />Guidelines, a Traffic Impact Analysis (TIA) is required if the proposed development is anticipated <br />to generate more than 3,000 daily trips. Based on the Orange County (County) Unified <br />Development Ordinance (UDO), a TIA is required if the proposed residential development is <br />anticipated to consist of 80 dwelling units or generate more than 800 daily trips. <br /> <br /> <br /> <br />70
