2013 No-Build The 2013 no-build condition assumes the roadway configuration on TH 10 / 169 following the completion of the Mn/DOT mill and overlay project and prior to develuptiient in the study area. This included revising the fuii movement access at 173rd Avenue to a right-in /right-out and maintaining the full movement access at 165 Avenue. The results of the analysis are shown in Table 21- 7. The TH 10 at 171St Avenue is the only result shown in the table since all other intersection in the study area would continue to operate at LOS C or better during both the AM and PM peak hours. The results of the analysis indicate that with closing of the 173rd Avenue intersection and with only background traffic growth (no development traffic), the intersection of TH 10 / 169 and 171St Avenue will be operating at a LOS F in the PM peak hour. This is primarily the result of the additional left turn traffic turning left from TH 10 / 169 to 171St Avenue. In order to mitigate this deficiency a dual left turn lane was assumed for southbound TH 10 / 169 to eastbound 171St Avenue. The results indicate that the overall intersection would then be operating at a LOS D with only the westbound 171St Avenue approach at a LOS E. The results of that mitigation are shown in Table 21-8. Table 21- 8 - 2013 No-Build with Phase 1 Development Completed The baseline condition for Phase 1 assumed the mitigation proposed in the 2013 no- build was completed and the phase 1 area was fully developed. Tables 21- 9, 21- 10 and 21-11 show the results of the Phase 1 development conditions with the baseline roadway configuration. The TH 10 at 171St Avenue is the only result shown in the table. All other intersection in the study area would continue to operate at LOS C or better during both the AM and PM peak hours.
