Northwestern College aster Plan Roseville, Mi esota Supple ent Findings of Fact Conclusions of L,aw And Order 23. Expansion of the College will increase the amount of solid waste generated by the school, but this increase will not create a risk of significant environmental effects, because the College provides for proper disposal of solid waste. 24. The project will not involve hazardous or toxic materials or contain above or below ground storage tanks, and thus will not create a risk of significant environmental effects due to such hazards. 25. The project will increase traffic by adding 690 parking spaces, which will have the effect of increasing congestion at several intersections. The following mitigation measures, which will be conditions of approval of the project by the City, will allow the area to absorb the additional traffic without creating a significant environmental effect from congestion: (1) implementing a traffic signal at Fairview Avenue/Lydia Avenue with an exclusive southbound left turn lane; (2) directing outbound right turns and inbound left turns to and from the west via the Northwestern College west gate during the afternoon peak hour; (3) adding an exclusive150-foot right turn lane at Lydia Avenue/College entrance to facilitate safe maneuvers for college-bound vehicles; (4) adding one additional left turn lane at Snelling Avenue/Lydia Avenue with left turn lanes extended to 200 feet; (5} adding one additional left turn lane at Snelling Avenue/County Road C-2 with left turn lanes extended to 200 feet; and {6} developing a Travel Demand Management Plan for campus students, staff, and employees. 26. In addition to managing congestion, the traffic mitigation measures discussed in Finding 26 will minimize the potential for significant environmental effects due to an increase in carbon dioxide air emissions. The traffic model by SimTraffic estimated that the Year 2018 cumulative scenario would include a decrease in carbon dioxide emissions by 60% at the Lydia Avenue/College entrance intersection and allow only a marginal 6% increase in emissions at the Lydia Avenue/Snelling Avenue intersection. 27. No evidence in the EAW process suggests the project will increase stationary source air emissions; The project will not create a risk of significant effects to air quality resulting from stationary source emissions. 28. During construction and after expansion, the project may generate increased noise levels, but the potential increase in noise will not pose the potential for environmental effects because the increased noise can be minimized through mitigation measures such as curfews, limited operating hours for trash pick-up, deliveries, and construction, and compliance with MPCA standard noise guidelines for public announcements from the sports fields. No evidence produced in the EAW process supports a conclusion that noise will or may lead to significant environmental effects. -5-
