Item 6 - Response to Parking Review Stantec Consulting Services Inc. Stantec 221 West Sixth Street Suite 600,Austin TX 78701-3411 October 20, 2016 File: 198110111 Attention: John Denholm III, P.E., PTOE Project Manager Lee Engineering 3030 LBJ Freeway, Suite 1660 Dallas, Texas 75234 Dear Mr. Denholm, Reference: Comment Response White Chapel Village Delta Hotel Parking Study Review Southlake, Tarrant County, Texas This is our response to comments received from your office on September 30, 2016. We have reviewed these comments and respond in the following manner: Action Comments 6. The 'time of day' distribution used for the hotel land use (ITE code 310) does not appear to come from the ITE Parking Generation Manual.The hourly distribution for the hotel land use does not appear reasonable as Oho of the hotel parking was shown in use throughout the overnight hours. Please update this distribution to match the data presented In the Parking Generation Manual, or indicate where the data was obtained. The time of day distribution for hotel land use has been updated to match the ITE Parking Generation Manual for hotel land use. 7. The time of day distribution for the 10,810 square feet of meeting space does not appear reasonable as no vehicles are assumed to be parked after 5:00 PM. An evening event for the space should be accommodated. The time of day distribution for the convention center land use has been updated to match the ULI Shared Parking Manual for convention center land use. 8. According to the study, City code requires a total of 370 parking spaces. City code does not include a conference center land use. Although the study does not specifically state the land use utilized,lt appears that the"lodge or fraternal organization"land use was used Instead of"community center' or"meeting rooms and places of public assembly." • If the "community center" use in the City code were utilized instead,424 parking Design with community in rninu October 20,2016 Ms. Barton-Holmes Page 2 of 3 Reference: Comment Response spaces would be required. This land use has been utilized by other hotel development parking studies previously submitted to the City. • The "meeting rooms and places of public assembly" parking requirement Is given in terms of number of seats rather than square footage. Industry data Indicates that a 6,000 square foot room could seat 400 people in a banquet configuration which would require 133 spaces according to City code. The total required for the site would then be 448 spaces. The proposed site has 10,810 square feet of meeting space with an unknown mix of room and seating configurations which would likely further increase the code required parking. • More Information about the proposed meeting space is required in order to evaluate the amount of parking necessary to-accommodate the use. The parking ratio has been changed to a seating ratio which provides a seating capacity that is consistent other developments with similar land uses that have recently been approved and developed within the area. 9. The report Indicates that the non-captive adjustments (85%for restaurant and conference center) and driver ratio (1000) utilized came from the shared parking methodology developed by the Urban Land Institute. However, these appear to be assumptions loosely based on the ULI methodology. Please further indicate how these were obtained or assumed. The non-captive adjustment and driver ratio are methodology taken from the ULI Shared Parking Manual and are based on engineering judgement. 10. The shared parking analysis presented does not take into account the interaction of other land uses within the development such as the planned office buildings and retail spaces. These uses should be included in the analysis. As this time, the land uses currently presented are the only uses that are currently planned to be built. It is the developer's intent to complete an additional shared parking study as further land uses are intended to be developed and constructed.
