6. Conclusions and Recommendations The traffic impacts of the proposed development, and background city developments, were thoroughly studied and the principal findings for the 2025 analysis are: • The proposed North Dayton Site development is expected to generate similar traffic compared to the 2030 Future Land Use plan, with 4,882 trips compared to approximately 4,820 trips during an average weekday (assuming 1/3 of the total residential units are developed). • During an average weekday, the a.m. peak hour trip generation is about 373 trips for the proposed North Dayton Site compared to 349 trips for the 2030 Future Land Use plan. The p.m. peak hour trip generation comparison is 492 trips and 453 trips for the proposed North Dayton Site and 2030 Future Land Use plan, respectively. • The TH 169 and CSAH 81 corridors are currently at or over the planning -level capacities for their types of facilities and volumes are expected to continue to increase into the future. • Due to background growth, other area developments, and the proposed North Dayton site, corridor volumes on 141 st Avenue near Brockton Lane are close to its nearing -capacity planning level. • Similarly, the intersections of Dayton River Road/TH 169, N Diamond Lake Road/Brockton Lane operate with failing delays by the 2025 No -Build scenarios while Dayton River Road/Pineview Lane operates with failing delays or queuing by 2025 Build scenario. Additional analysis was completed for the year 2040 with the following findings: • The proposed North Dayton Site development is expected to generate significantly less traffic compared to the 2030 Future Land Use plan, 16,820 trips compared to approximately 20,822 trips during an average weekday. • The peak hour trip generation has a similar comparison with the proposed North Dayton plan generating about 15% less traffic than would be expected under the 2030 Land Use plan. • Additional roadway upgrades are expected by 2040 including the 1-94 interchange connecting 1-94, CSAH 81, French Lake Road, Brockton Lane, and Zanzibar Lane. • The TH 169 and CSAH 81 corridors will continue to operate above capacity as volumes from general growth, specific development in the area, and this proposed North Dayton development contribute to higher volumes. • Dayton River Road, Brockton Lane, and 141 st Avenue begin to see volumes close to or just above the nearing congestion range under the 2040 Build scenarios. • Dayton River Road/TH 169 operates with failing LOS delays under the expanded configuration by the 2040 No -Build Scenario. Further expansion may not be feasibly due to adjacent developments and the roadways proximity to the northern river crossing. Traffic Impact Study 27 North Dayton Development =CONSULTING
