<br /> <br />CENTERVILLE RD (CSAH 21/CSAH 59) AT ASH ST (CR J)/WILKINSON LAKE BLVD PAGE 19 <br />ICE REPORT <br />S.A.P. TBD <br />WSB PROJECT NO. 2988-080 <br />CITY OF LINO LAKES, MN <br /> <br />2038 Build Conditions: The 2038 build conditions assume that the proposed Hawkins <br />residential project is fully developed. Similar to the 2038 no-build condition analysis the 2038 <br />build conditions with existing lane geometrics and all-way stop control show the intersection of <br />Centerville Road (CSAH 21/CSAH 59) at Ash Street (CR J) would be operating at an overall <br />LOS F in the AM and PM peak hours. Specifically the southbound approach, northbound <br />left/through movement and the westbound right turn movements are showing unsatisfactor y <br />levels of service. The results of the 2038 no-build condition traffic operations analysis are <br />summarized in Table 9. Detailed modeling results are provided in Appendix D. <br /> <br />Table 9: 2038 Build Condition Operations Summary <br />Intersection AM Peak PM Peak Control Location Appr <br />Movement Delay (LOS) <br />Intersection <br />Delay(LOS) <br />Movement Delay (LOS) Intersectio <br />n <br />Delay/LOS Left Through Right Left Through Right Stop Centerville Rd <br />(CSAH 21/CSAH 59) <br />at Ash St (CR J) <br />NB 17.1(C) 11.1 (B) <br />236.8 (F) <br />62.0 (F) 20.3 (C) <br />185.0 (E) WB 28.0 (D) 24.9 (C) 14.3 (B) 196.1(F) <br />SB 411.8 (F) 332.8 (F) <br />EB 14.7 (B) 18.9 (B) Stop Ash St at 20th <br />Ave/I35E Ramp <br />WB 10.4 (A) <br />7.8 (A) <br />9.9 (A) <br />4.9 (A) SB 53.9 (F) 86.9 (F) <br />EB 9.1 (A) 10.8 (A) <br /> <br />In addition the southbound approach at the intersection of Ash Street (CR J) at 20th Avenue/I35E <br />Ramp would also be operating an LOS F during the AM and PM hours. As discussed previously <br />MnDOT has been considering future roundabout improvement to the I35E ramp intersections. <br />With the addition of roundabouts at these intersections all movements would operate at <br />acceptable levels in the future. <br /> <br />Traffic Signal Alternative Analysis <br /> <br />This alternative assumes a new traffic control signal at the intersection of Centerville Road <br />(CSAH 21/CSAH 59) at Ash Street (CR J). In addition, based on the all-way stop analysis, the <br />following roadway lane configuration was included: <br /> <br />• Northbound Centerville Road (CR 59) – one left turn, one through and one right turn lane <br />• Southbound Centerville Road (CR 21) – one left turn, one through/right turn lane <br />• Eastbound Wilkinson Lake Blvd – one left turn, one through/right turn lane <br />• Westbound Ash Street (CR J) - one left turn, one through and one right turn lane <br /> <br />Figure 10 shows the proposed intersection configuration. <br /> <br />2018 Traffic Signal Build Conditions: The 2018 build conditions assume a traffic signal <br />system with the proposed lane configuration with the proposed Hawkins residential project fully <br />developed. Based on these assumptions the intersection would be operating at an overall LOS B <br />in the AM and PM peak hours. The results of the 2018 traffic signal build condition traffic <br />operations analysis are summarized in Table 10. Detailed modeling results are provided in <br />Appendix D.
