STAFF ANALYSIS AND RECOMMENDATION

REZONING REQUEST

The study area analyzed the following intersections:

• N. Harrison at I-40 Westbound ramps
• N. Harrison at I-40 Eastbound ramps
• N. Harrison at SAS Campus Drive
• N. Harrison at Weston Parkway

For this project, the Institute of Transportation Engineers Trip Generation Manual was used to estimate the projected trips generated by the proposed project. The project can be expected to generate a total of 2,190 vehicle trips on a weekday daily basis of which 313 would occur in the weekday AM peak hour, and 285 trips would occur in the weekday PM peak hour. This traffic was then distributed to and from N. Harrison Avenue, Interstate 40 and Weston Parkway.

Intersection analyses indicated that under existing conditions all signalized intersections within the study area operate at acceptable service levels during both the weekday AM and PM peak hours with the exception of the intersection of N. Harrison Avenue at Weston Parkway which currently operates at a level of service F during the weekday PM peak hour. With the addition of background development traffic, normal traffic growth and roadway improvements obligated to the Arboretum development, the intersection of N. Harrison Avenue at Weston Parkway will continue to deteriorate in service level with the development of additional development at the SAS Institute.

To enhance future operations within the study area and to mitigate the impact of future development at the SAS Institute, the following improvements are recommended:

• N. Harrison Avenue at I-40 Westbound ramps—retime the signal within the existing cycle length during the weekday peak hours.
• N. Harrison Avenue at I-40 Eastbound ramps—While the ramp movements operate poorly today and in the future, the best solution to this volume related problem is to consider a new interchange to I-40 in proximity to these ramps and the creation of a second access point into SAS campus from Old Trenton Road. Both these solutions will offer the motorist more route choices and better distribute traffic in this area.
• N. Harrison Avenue at Weston Parkway—The Arboretum development (a mixed use development under construction at the southwest corner of the intersection) has committed to add an additional left turn lane from N. Harrison Avenue onto Weston Parkway and to add a travel lane along Weston Parkway from the intersection to Harrison Oaks Drive. In addition, the NCDOT will be widening N. Harrison Avenue from Weston Parkway to Maynard Road starting in the Spring of 2000. The widening project will result in a four lane divided roadway with a raised median.

The combination of the Arboretum improvements and the NCDOT widening of Harrison Avenue will result in the Weston Parkway at N. Harrison Avenue intersection improving its service level from F to E.

Land Use Plan Analysis: The proposed rezoning is in conformance with the Land Use Plan which calls for Office and Institutional uses in this location.

Recommendation: From a transportation perspective, the SAS institute has agreed to delay receipt of a certificate of occupancy for additional development until the improvements are completed from N. Harrison Avenue and for the intersection of Weston Parkway and N. Harrison Avenue. Therefore, the transportation related impacts of the rezoning for SAS could be effectively addressed prior to development resulting from the rezoning.

Staff Recommendation: Staff recommends approval.
