The proposed project is to be located north-east of the existing Ogden Elementary School in New Hanover County, NC. The project proposes 24 dwelling units of townhomes. Two (2) new restricted site access points are proposed. A right-in only site access is proposed to be located approximately 540 feet east of the existing roundabout at Middle Sound Loop Road and Darden Road. A right-out only site access is proposed to be located approximately 418 feet south of the roundabout. Executive Summary and Conclusion DAVENPORT was retained to determine the potential traffic impacts of this project and to identify transportation improvements that may be required to accommodate the impacts of both background traffic and new development traffic. Based on the trip generation rates and equations published in Trip Generation (Institute of Transportation Engineers, 10th Edition), this development has a trip generation potential of 141 daily trips, 12 trips (3 entering 9 exiting) in the AM peak hour and 17 trips (11 entering 6 exiting) in the PM peak hour.

In 2022 future no build conditions (without the project site trips) LOS E is expected in the AM peak hour and LOS B in the PM peak hour. In 2022 future build conditions (which includes the proposed Home Office: Wilmington Regional Office: Serving the Southeast since 2002 119 Brookstown Ave. Suite PH1 3722 Shipyard Boulevard, Suite E Winston-Salem, NC 27101 Wilmington, NC 28403 Main: 336.744.1636; Fax: 336.458.9377 Main: 910.251.8912; Fax: 336.458.9377 2 project site trips) the LOS is expected to remain unchanged. Overall, a slight increase (1.9 seconds per vehicle AM and 0.3 seconds per vehicle PM) in delay is expected at the roundabout. DAVENPORT is in agreement with NCDOT study, dated February 1, 2018 and conclusions regarding the Demarest Pointe development.

Studies have shown that left turns account for 72% of driveway crashes for driveways located near intersections. Left turn movements are typically associated with angle crashes which can often result in injuries. Right turns are more often associated with rear end or sideswipe crashes typically resulting in property damage only. Conclusion In conclusion, this study has reviewed the impacts of both background traffic and proposed development traffic. There is negligible impact from traffic generated by this development and no traffic mitigation measures are recommended.

The vicinity map and the existing lane geometry are illustrated in Figure 2 and Figure 3 respectively. Traffic counts collected on December 12, 2017 were used to determine the 2020 base volumes at this study intersection. A 2% annual growth rate, given from a NCDOT previous study, dated February 1, 2018, was applied to the 2017 traffic to obtain the 2020 base volumes. The 2017 count and method were used to reflect the traffic conditions prior to COVID-19 pandemic. The 2020 base volumes were projected out to a future analysis year of 2022 by applying a 2% annual traffic growth rate. 2020 base volumes and 2022 future no build volumes are shown for AM and PM peaks in Figures 4 and 5, respectively. The trip generation potential for this site was projected based on the 10th edition of ITE Trip Generation Manual. Table 1 presents the results. Site trips for this project were distributed based on the existing traffic patterns and engineering judgment. The trip distribution model is shown in Figure 6. The 2022 build-out traffic volumes were obtained by summing the 2022 future no build volumes and site trips generated by the proposed project. Site trips are shown in Figure 7. The 2022 future build volumes are shown for AM and PM peaks in Figure 8.

Queue lengths were also reviewed based on SIDRA 8.0 results. Based on NCDOT standards, roundabout environmental factor would be adjusted to 1.2 to reflect U.S. drivers’ inexperience with roundabout driving. In this specific location, this roundabout has been in place for 10 years. Therefore, based on engineering judgement, the environmental factor was adjusted to 1.0 to reflect the familiarity of the roundabout. In general, the analysis for this project was conducted utilizing commonly accepted NCDOT standards.

Middle Sound Loop Road at Darden Road (ROUNDABOUT) The intersections were analyzed during the AM (7-9 am) and PM (4-6 pm) peaks for the following conditions: • 2020 Base Conditions • 2022 Future No-Build Conditions • 2022 Build Conditions Capacity Analysis Overall, the study intersection currently operates at level of service (LOS) D and B during the AM and PM peak hours respectively, as shown in Table 2 on the next page. In 2022 future no build conditions (without the project site trips) LOS E is expected in the AM peak and LOS B in the PM peak. In 2022 future build conditions (which includes the proposed project site trips) the LOS is expected to remain unchanged. Overall, a slight increase (2 seconds per vehicle AM and 0.3 seconds per vehicle PM) in delay is expected at the intersection.

Based on the analysis, the northbound queue at the roundabout will extend past the proposed right-out only access. This queue length is expected to be short-lived as majority of the traffic during the morning peak is school traffic. Based on the NCDOT turn lane warrant charts, no turn lanes are warranted. Therefore, it is recommended to design the site access according to NCDOT standards. Figure 10 shows the recommended improvements.

Based on the trip generation rates and equations published in Trip Generation (Institute of Transportation Engineers, 10th Edition), this development has a trip generation potential of 141 daily trips, 12 trips (3 entering 9 exiting) in the AM peak hour and 17 trips (11 entering 6 exiting) in the PM peak hour. Roundabout Capacity Analysis Overall, the study intersection currently operates at level of service (LOS) D in the AM peak hour and B during the PM peak hour, as shown in Table 2. In the 2022 future no build conditions (without the project site trips) LOS E is expected in the AM peak hour and LOS B in the PM peak hour. In the 2022 future build conditions (which includes the proposed project site trips) the LOS is expected to remain unchanged. Overall, a slight increase (1.9 seconds per vehicle AM and 0.3 seconds per vehicle PM) in delay is expected at the intersection. DAVENPORT is in agreement with NCDOT study, dated February 1, 2018 and conclusions regarding Demarest Pointe development. The roundabout capacity analysis was also performed for a 27 townhome alternative. Considering the minimal additional traffic volumes generated by the 27 townhome alternative compared to the 24 townhome alternative, the AM peak hour delay would increase by 0.4 seconds per vehicle compared to the 24 townhome alternative. There would be no change in delay per vehicle for the PM peak hour.

Please see below NCDOT responses to the items below related to the Demarest Pointe proposed development: 1.Requirement for a Traffic Impact Analysis (TIA); A TIA will not be required by NCDOT and is below the WMPO and County thresholds for requirement of a TIA. 2.Location and proposed alignment for Demarest Pointe entrance, point of Ingress: NCDOT is in agreement with the entrance access as proposed in your conceptual plan. A turn lane will not be required based on our review of the roadway and site traffic volumes. 3.Location and proposed alignment for Demarest Pointe exit, point of Egress; NCDOT is in agreement with the exit access as proposed in your conceptual plan. 4.Commentary regarding preference specific to Egress onto Middle Sound Loop Road, as shown on the attached Master Development Plan or is there a preference for the possible alternate Egress location utilizing the access/utility/drainage easement provided through 3618 Middle Sound Loop Road onto Pickway Court to Middle Sound Loop Road. NCDOT does not have a preference with regard to exit access alternatives described above. 5.General internal vehicular circulation alignment and vehicular flow pattern of the Demarest Pointe neighborhood design relationship (one way vehicular pattern, right in, right out) to the existing vehicular patterns of Middle Sound Loop Road, the Middle Sound Loop Road Round - A - Bout and Ogden Elementary School points of Ingress, Egress and vehicular flow patterns. The Demarest Pointe access design provides excellent access management with limited movement right-in and right-out driveways instead of traditional full movement intersections. The roundabout provides a nearby intersection for vehicular site traffic to make u-turn type movements to accommodate left-in and left-out movements related to the development site. NCDOT does not have any concerns related to the development exit access relative to the school driveways. In general, the development design is well thought out in regard to circulation and flow of traffic. Please let us know if you have any questions or if additional information is needed.
