Mitiation 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. 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 independent of the project traffic. • 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 • Sunwood Drive at Industry Avenue • Sunwood Drive at Armstrong Boulevard • NS3 Street at Industry Avenue The left turn volumes from the EW1 parkway onto both Armstrong and Ramsey Boulevard cannot be accommodated at an acceptable LOS under stop control and require signalization to achieve acceptable operations. However, the close spacing between the intersections of the EW1 21-8
