Summary of Environmental Impact. Direct environmental impacts due to the traffic analysis are addressed in Items 22 and 24, which address vehicle related air emissions, and dust, odors, and noise, respectively. Mitigation element. Analysis of the intersection operations indicates that lane additions and installation of intersection channelization and traffic signals would be adequate to mitigate the project impacts at the intersections in the study area. The following roadway widenings are suggested: • Ramsey Boulevard —widen to five lane cross section south of Industry Avenue to provide two through lanes in each direction and a left turn lane/center median • Industry Avenue —widen to five lane cross section west of Ramsey Boulevard to provide two through lanes in each direction and a left turn lane/center median The existing cross sections on Armstrong Boulevard north of the railroad, Sunwood Drive and Industry Avenue east of Ramsey, and Sunfish Lake Boulevard north of the railroad would be adequate to meet the future demand Turn lanes and lane adjustments would be needed at the following intersections: • TH 10 at Armstrong Boulevard —add an eastbound and a westbound through lane on the intersection approaches; add an eastbound and a southbound left turn lane and a southbound right turn lane. • TH 10 at Ramsey Boulevard —add an eastbound and a westbound through lane on the intersection approaches; add an eastbound and a southbound left turn lane and a westbound right turn lane. Provision for pedestrian crossings of TH 10 needs to be included. A southbound through lane and a northbound left turn lane and northbound through/right lane would need to be added to serve the Rivenwick 3rd Subdivision traffic and traffic destined for the Mississippi West Regional Park independent of the project traffic. Traffic demands from these other land uses should be considered when the intersection improvements are designed. • TH 10 at Sunfish Lake Boulevard —add an eastbound and a westbound through lane on the intersection approaches; convert the southbound approach from a through/left turn lane and a right turn lane to through/right turn lane and two left turn lanes (this adds one lane to the approach). • Industry Avenue at Ramsey Boulevard —add a southbound right turn lane; eastbound and northbound approaches would be widened by the above recommendations. • Sunwood Drive at Industry Avenue —modify the shared lanes on the northbound, eastbound and westbound approaches to provide left turn lanes and shared through/right turn lanes The following stop -controlled intersections would need to be signalized: • Ramsey Boulevard at Industry Avenue • Armstrong Boulevard at Industry Avenue • Industry Avenue at Sunfish Lake Boulevard • Ramsey Boulevard at Sunwood Drive 21-8
