Trinity Landing Transportation Impact nalysis Prepared for Lutheran Services Carolinas New Hanover County, NC pril 7, 217 1. Introduction The proposed Trinity Landing development is to be located on Masonboro Loop Road in New Hanover County, North Carolina. The development is planned to consist of 22 senior adult housing dwelling units and amenities including a 7,35 square foot restaurant, a 2,15 square foot convenience market, a 9 square foot beauty spa, and a 6,9 square foot wellness center. The development will utilize one (1) access point on Masonboro Loop Road. Figure 1 presents the preliminary site plan. Figures 2 and 2B show the site location map and vicinity map, respectively. DVENPORT was retained to determine the potential traffic impacts of this development and to identify transportation improvements that may be required to accommodate the impacts of both background traffic and new development traffic. The following intersections were included in the study: Masonboro Loop Road at Trailing Vine Lane Per coordination with the WMPO, two development scenarios were analyzed in this study: one with amenities open to the public, and the other with the amenities open to the Lutheran Services Carolinas community, their residents, and their guests. The above-mentioned intersection was analyzed for the following scenarios: 217 Existing Conditions 22 Future No Build Conditions 22 Future Build-Out Conditions with amenities Open to the Public 22 Future Build-Out Conditions with amenities open to the Lutheran Services Carolinas community, their residents, and their guests 22 Future Build-Out with Improvements (as necessary) The build-out analysis year for this project was assumed to be 22. The M (7 am 9 am) and PM (4 pm 6 pm) weekday peaks were studied. The WMPO, County, and North Carolina Department of Transportation (NCDOT) were contacted to obtain background information and to ascertain the elements to be covered in this Transportation Impact nalysis (TI). Information regarding the property was provided by Lutheran Services Carolinas. 4/7/216 16273 Trinity Landing Transportation Impact nalysis 2

5. Capacity nalysis 5.1 Level of Service Evaluation Criteria The Transportation Research Board s Highway Capacity Manual (HCM) utilizes a term level of service to measure how traffic operates in intersections and on roadway segments. There are currently six levels of service ranging from to F. Level of service represents the best conditions and Level of Service F represents the worst. Synchro Traffic Modeling software was used to determine the level of service for studied intersections. ll worksheet reports from the analyses can be found in the ppendix. Table 5.1 Highway Capacity Manual Levels of Service and Control Delay Criteria Signalized Intersection Unsignalized Intersection Level of Service Control Delay Per vehicle (sec) Level of Service Delay Range (sec) 1 1 B 1 and 2 B 1 and 15 C 2 and 35 C 15 and 25 D 35 and 55 D 25 and 35 E 55 and 8 E 35 and 5 F 8 F 5 4/7/216 16273 Trinity Landing Transportation Impact nalysis 21
5.2 Level of Service Results The results of the study are discussed by intersection below: Masonboro Loop Road at Trailing Vine Lane The eastbound approach of this unsignalized intersection currently operates at LOS C in the M and PM peaks. In 22 future no build conditions, it is expected to remain unchanged. With the addition of site traffic, with amenity uses open to the public, the westbound approach is projected to operate at LOS F in the M peak and LOS E in the PM peak. With the addition of site traffic, with amenity uses NOT open to the public, this intersection is projected to operate at LOS F in the M peak and LOS E in the PM peak. The LOS E/F condition is typical for stop-controlled approaches onto major streets like Masonboro Loop Road, and the delay is expected to be short-lived. Based on turn lane warrant analysis, a 1-foot northbound right turn taper turn lane on Masonboro Loop Road is recommended for build-out in both conditions of amenity uses open and not open to the public. This turn lane was included in the analysis of both scenarios with and without the amenity uses open to the public. More information on the turn lane warrant can be found in the appendix. 4/7/216 16273 Trinity Landing Transportation Impact nalysis 22

6. Summary and Conclusion The proposed Trinity Landing development is to be located on Masonboro Loop Road in New Hanover County, North Carolina. The development is planned to consist of 22 senior adult housing dwelling units, a 7,35 square foot restaurant, a 2,15 square foot convenience market, a 9 square foot beauty spa, and a 6,9 square foot wellness center. The development will utilize one (1) access point on Masonboro Loop Road. If the amenity uses are open to the public, the trip generation indicates that the proposed development is expected to generate a net total of 1,57 trips per day with 63 trips in the M peak and 93 trips in the PM peak. If the amenity uses are NOT open to the public, the trip generation indicates that the proposed development is expected to generate a net total of 757 trips per day with 42 trips in the M peak and 51 trips in the PM peak. DVENPORT was retained to determine the potential traffic impacts of this development and to identify transportation improvements that may be required to accommodate the impacts of both background traffic and new development traffic. Per the developer s plan and commitments, a northbound right turn into the site is desired. Based on turn lane warrant analysis, a 1-foot northbound right turn taper is recommended for build-out in both conditions of amenity uses open and not open to the public. In conclusion, this study has reviewed the impacts of both background traffic and proposed development traffic, and has provided recommendations to accommodate future traffic. Please note the proposed site access should be designed according to NCDOT standards. 4/7/216 16273 Trinity Landing Transportation Impact nalysis 26
