2.16.01 ATTACHMENT COMBINED APPLICATION FOR CSAH 3/CR I RECONSTRUCTION PROJECT 8. Sequencing Considerations 1. No Build Alternative This alternative includes no upgrades to the existing roadway other than potential future overlays on existing pavement. This alternative does not improve congestion, safety, or geometrics or provide an adequate east-west corridor. The No Build Alternative would not correct the identified deficiencies within the project area and is therefore not feasible. 2. Alternate Location Four location altemates for this project were considered. All location alternates included the elimination of 90 degree turns and installation of traffic signals at the single intersection of CR I and Lexington Avenue. A brief description of the alternates follows: • Alternate 1 included new construction west of Hamline Avenue and east of Lexington Avenue, and reconstruction of the existing CR I between Hamline Avenue and Lexington Avenue. This alternate would require a parkland conversion process, impact 3 acres of wetland, require an on-grade bridge, and require home acquisition. • Alternate 2 included new construction west of Hamline Avenue and west of Lexington Avenue, and reconstruction of a portion of the existing CR I east of Hamline Avenue. This alternate would impact 2 acres of wetland, require a parkland conversion process, require a vertical crest on a horizontal curve, and require an on-grade bridge. • Alternate 3 included new construction east of Hamline Avenue and west of Lexington Avenue, and reconstruction of a small portion of the existing CR I between Hamline Avenue and Lexington Avenue. This alternate would impact 1.2 acres of wetland, require displacement of an established business, require a vertical crest on a horizontal curve, and require an on- grade bridge. • Alternate 4 was the most direct path and included new construction between Hamline Avenue and Lexington Avenue. This alternative would impact 3.4 acres of a DNR Protected Water(59P) 3, Chosen Alternative The chosen altemative is an abbreviated version of Alternate 3 described above. This alternative includes reconstruction of existing CR I east of Hamline Avenue and new construction west of Lexington Avenue as indicated on the enclosed plans. This alternative impacts 0.9 acres of wetland. This alternative improves congestion, safety, and geometrics, and provides an adequate east-west corridor. This altemative removes high traffic from the elementary school and signalizes an intersection at which significant congestion and accidents occur.
