Item 7A TIA amendment Stantec e!��L 2M? Memo To: Carl Schwab From: Carl LaFerney, P.E., PTOE, MBA RREAF Real Estate & Note Stantec Consulting Services, Inc. Acquisition 2435 N. Central Expressway Suite 750 4245 N. Central Expressway Suite 420 Richardson, Texas 75080-2793 Dallas,Texas 75205 Date: July 18, 2016 Reference: White Chapel Village Memorandum 1.0 INTRODUCTION Stontec Consulting Services, Inc. has been retained by RREAF Real Estate & Note Acquisitions to provide a professional opinion of the impact on adding 20 rooms to the hotel within the proposed White Chapel Village site, located southwest of the interchange of SH 114 and White Chapel Boulevard in Southlake, TX. A traffic impact analysis (TIA) previously performed by Stantec for White Chapel Village was submitted on October 22, 2015. The TIA included the proposed hotel as the Phase 1 build-out of the site, with the remaining land uses being built in the final build-out. A horizon year of five years was also part of the TIA. This memo provides a qualitative analysis of the trip generation and distribution of the additional hotel rooms and a professional opinion as to whether additional traffic improvements would be required. 2.0 TRIP GENERATION AND DISTRIBUTION Generating traffic for proposed developments is typical based on information in Trip Generation, 9th Edition, 2012 and the Trip Generation Handbook, 2nd edition, 2004, developed by the Institute of Traffic Engineer (ITE). The rates and equations in these reports were applied to the development to determine the anticipated trips generated from the development where applicable. The trip generation comparison between the previous TIA and the revised hotel with additional rooms is shown in Table 1.The trip generation analysis can be found in Appendix A. Table 1: Trip Generation Comparison Hotel AM Peak Tris PM Peak Trips Rooms In Out In Out Previous White Chapel Village TIA Submission 220 69 48 67 65 Revised Trip Generation 240 75 52 73 71 Chane +20 +6 +4 +6 +6 The hotel as part of the previously-submitted TIA included 220 rooms. After approval from the City of Southlake, the hotel size increased to 240 rooms. The revision would add no more than six trips inbound or outbound during either peak hour.

The resulting volumes were calculated for each of the study intersections from the previous TIA. The change in volume due to the added hotel rooms is shown in Figure 1. As can be seen in the figure, the change in volume would not exceed three vehicles per hour at any of the turning movements for each of the study intersections, during either peak hour.

This included a Phase 1 build-out (hotel only), full build-out in 2020, and horizon year in 2025. Recommendations based on the impact of this site included the following: • Deceleration lanes for Driveways 3 and 4; and • Traffic Signal with hooded left turn for Driveway 1 at 2020 Full Build-out. Recommendations based on the impacts of other developments or city recommendations included the following: • Traffic signal at the Kirkwood Boulevard/White Chapel Boulevard borne by the Carillon retail/office development;and • Add a lane to the westbound approach at the White Chapel Boulevard/SH 114 westbound frontage road intersection, update phasing to 4-phase, and optimize signal timing. From Figure 1, the change in volume would not exceed three vehicles per hour at any of the turning movements for each of the study intersections, during either peak hour. Though Stantec has not conducted a formal capacity analysis with the additional hotel trips, it is the professional opinion of the Engineer that the additional volumes will have a negligible impact on traffic operations at all studies intersections. The Engineer recommends no additional improvements beyond those described in the previous TIA. STANTEC CONSULTING SERVICES INC.
