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.

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 trip distribution for the revised hotel matched the external and infernal trip distribution for the
project site in the previous TIA submission. 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.

3.0 RECOMMENDATIONS
Stantec engineers reviewed the recommended improvements from the previously submitted TIA.
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.
