Based on an updated access configuration, Lee Engineering (LEE) has prepared a preliminary assessment of the impact of those changes on the study performed for the multi-family residential development located in Arlington, Texas. The proposed access point to Arbrook Boulevard, described as the Northern Driveway, is moved west, and is limited to right turns in and right turns out. The updated site driveway location is shown in Figure 1. The existing lane configurations are shown in Figure 2. Figure 3 shows the resulting proposed lane configurations for the area roadways. The existing traffic volumes can be found in Figure 4. This study involved two (2) scenarios, with the Highlander Boulevard extension and without the Highlander Boulevard extension. Updates to the trip distribution and trip assignment have been made based on the changes to the driveway location provided by the client. For the scenario without the Highlander Boulevard extension, 35% of traffic was removed from the intersections of Embarcadero Drive and Collins Street and the Arbrook Boulevard and Collins Street. 19 trips were removed in the AM peak hour and 56 trips were removed in the PM peak hour. 20% of this traffic was added to eastbound Highlander Boulevard at Center Street. This resulted in 11 added trips in the AM peak hour and 32 added trips in the PM peak hour to the Highlander Boulevard at Center Street intersection that was predicted to operate at LOS C or better in the TIA. 15% of the remaining traffic was added to eastbound Arbrook Boulevard at Center Street. This resulted in 8 added trips in the AM peak hour and 24 added trips in the PM peak hour to the Arbrook Boulevard at Center Street intersection that was predicted to operate at LOS D or better in the TIA. 25% of traffic was removed from the proposed northern driveway and relocated at the proposed southern driveway, adding 39 trips in the AM peak hour and 26 trips in the PM peak hour at the proposed southern driveway. These updates can be found in Figure 5 and Figure 6. 3030 LBJ Freeway, Suite 1660, Dallas, TX 75234 (972) 248-3006 office (972) 248-3855 fax | www.leeengineering.com Page 1 of 2 3030 LBJ FREEWAY SUITE 1660 DALLAS, TEXAS 75234 Updated Proposed Site Plan Figure 1 972-248-3006 FAX 972-248-3855 DALLAS - PHOENIX - ALBUQUERQUE OKLAHOMA CITY - SAN ANTONIO Highlander Blvd STOP LEGEND Stop-Controlled Approach Signalized Intersection Lane Configuration Study Intersection DALLAS, TEXAS75234 SUITE 1660 3030 LBJFREEWAY 972-248-3006 FAX972-248-3855 DALLAS -PHOENIXALBUQUERQUE OKLAHOMA CITY-SAN ANTONIO S Center St Existing Intersection LaneConfigurations W ArbrookBlvd Embarcadero Dr S T O P S Collins St STOP Commercial Dwy NOT TOSCALE Figure 2 N Highlander Blvd STOP LEGEND Stop-Controlled Approach Signalized Intersection Proposed LanebytheApplicant Proposed LaneConfiguration Existing LaneConfiguration Study Intersection DALLAS, TEXAS75234 SUITE 1660 3030 LBJFREEWAY 972-248-3006 FAX972-248-3855 DALLAS -PHOENIXALBUQUERQUE OKLAHOMA CITY-SAN ANTONIO S Center St STOP Southern Driveway with andwithout HighlanderBoulevard Extension Analysis willbeperformed undertwoscenarios: Proposed Intersection LaneConfigurations Highlander BlvdExtension W ArbrookBlvd 2.0 WiththeproposedHighlander BoulevardExtension 1.0 WithouttheproposedHighlander BoulevardExtension Northern Driveway STOP STOP Embarcadero Dr S T O P S Collins St STOP Commercial Dwy NOT TOSCALE Figure 3 N Highlander Blvd LEGEND [24-Hour Volume] AM PeakHour(PMHour) Study Intersection DALLAS, TEXAS75234 SUITE 1660 3030 LBJFREEWAY 972-248-3006 FAX972-248-3855 93 (468) 10 (63) 39 (98) 24 (187) 7 (56) 40 (107) DALLAS -PHOENIXALBUQUERQUE OKLAHOMA CITY-SAN ANTONIO 38 (188) 91 (348) 123 (407) [4,708] 42 (78) S Center St [4,722] 6 (18) 4 (30) 122 (327) 62 (189) 117 (255) 90 (157) 27 (44) 49 (259) Existing (2020) PeakHourTraffic Volumes [7,772] [5,252] W ArbrookBlvd Embarcadero Dr 70 (274) 68 (409) 33 (140) 16 (20) 5 (22) 3 (0) 52 (62) 54 (141) 621 (1,227) 522 (923) S Collins St 0 (0) 34 (43) 59 (25) 43 (123) 0 (2) 1 (0) 0 (0) 121 (316) 78 (102) 715 (960) 589 (729) 50 (45) 5 (3) 91 (116) Commercial Dwy NOT TOSCALE Figure 4 N Highlander Blvd DALLAS, TEXAS75234 SUITE 1660 3030 LBJFREEWAY 972-248-3006 FAX972-248-3855 30% 40% 5% DALLAS -PHOENIXALBUQUERQUE OKLAHOMA CITY-SAN ANTONIO 5% (20% ) 10% (5% ) 15% S Center St (20% ) 5% 45% (25%) (40%) (15% ) 5% (5% ) Southern Driveway Without Highlander BoulevardExtension W ArbrookBlvd LEGEND Assumed Directional Distribution Inbound (Outbound)Percentages Study Intersection (5%) 40% Northern Driveway (35% ) 5% Embarcadero Dr (30%) (5%) (5%) (30% ) S Collins St 5% Commercial Dwy NOT TOSCALE Figure 5 N N Highlander Blvd DALLAS, TEXAS75234 SUITE 1660 3030 LBJFREEWAY 972-248-3006 FAX972-248-3855 16 (48) 22 (64) 3 (8) DALLAS -PHOENIXALBUQUERQUE OKLAHOMA CITY-SAN ANTONIO 31 (21) 3 (8) 8 (5) 8 (24) 5 (16) S Center St 3 (8) 39 (26) 62 (41) 31 (21) 25 (72) 3 (8) 23 (15) 8 (5) Southern Driveway Without Highlander BoulevardExtension W ArbrookBlvd LEGEND AM PeakHour(PMHour) Study Intersection Peak Hour Traffic Volumes Total Site Generated 22 (64) 8 (5) Northern Driveway 55 (36) 3 (8) Embarcadero Dr 47 (31) 8 (5) 8 (5) 47 (31) S Collins St 3 (8) Commercial Dwy NOT TOSCALE Figure 6 N N Highlander Blvd DALLAS, TEXAS75234 SUITE 1660 3030 LBJFREEWAY 972-248-3006 FAX972-248-3855 25% 30% 5% DALLAS -PHOENIXALBUQUERQUE OKLAHOMA CITY-SAN ANTONIO (20% ) 5% (5% ) 10% (10% ) 15% S Center St 50% (20% ) 5% 15% (35%) (40%) (15% ) 5% (5% ) Southern Driveway Highlander BlvdExtension With Highlander BoulevardExtension W ArbrookBlvd LEGEND Assumed Directional Distribution Inbound (Outbound)Percentages Study Intersection (5%) 35% (10%) Northern Driveway 15% (25% ) 5% Embarcadero Dr (20%) (5%) (5%) (10%) (20% ) S Collins St 5% 15% Commercial Dwy NOT TOSCALE Figure 7 N Highlander Blvd DALLAS, TEXAS75234 SUITE 1660 3030 LBJFREEWAY 972-248-3006 FAX972-248-3855 14 (40) 17 (48) 3 (8) DALLAS -PHOENIXALBUQUERQUE OKLAHOMA CITY-SAN ANTONIO 31 (21) 8 (5) 3 (8) 16 (10) 8 (24) 5 (16) S Center St 28 (79) 31 (21) 8 (24) 3 (8) 3 (8) 55 (36) 62 (41) 23 (15) 8 (5) Southern Driveway Highlander BlvdExtension With Highlander BoulevardExtension W ArbrookBlvd LEGEND AM PeakHour(PMHour) Study Intersection Peak Hour Traffic Volumes Total Site Generated 19 (56) 8 (5) 16 (10) Northern Driveway 8 (24) 39 (26) 3 (8) Embarcadero Dr 31 (21) 8 (5) 8 (5) 16 (10) 31 (21) S Collins St 3 (8) 8 (24) Commercial Dwy NOT TOSCALE Figure 8 N N.
