- - ------- . Honorable Mayor and City Council January 9, 1993 Page Three Glen Hill Road and Asbury Avenue could be closed. The County's share of costs would include normal geometric improvements on the Hamline Avenue leg of the intersection and one-fourth of the signalization. The City would be responsible for funding the Old Snelling Avenue improvements and one-fourth of the signal. Any additional features, such as sidewalk, would be 100% City funded. Alternative 1 could be expanded to include construction of a frontage road along the west side ofTH 51 between Old Snelling Avenue and Glen Hill Road. This alternative would allow for closure of the entrance/exit on TH 51 at Glen Hill Road. Further investigation would be necessary to determine the need for additional right-<>f-way. The impacts on surrounding properties, for example, the northwest corner of Glen Hill and TH 51 and the wetland area south of Old Snelling Avenue, could make the frontage road option costly. Mr. O'Keefe indicated that MnDOT would most likely participate in roadway costs for this option. FRONTAGE ROAD - ALTERNATIVE 2 . The proposed frontage road improvement consists of construction of a 32-foot wide road along the west side of TH Sl between Old Snelling Avenue and Lydia Avenue. The proposed location is shown on Exhibit 2. The frontage road alignment would require additional right-of- way acquisition, a portion of which is in the City of Roseville. The estimated construction and project costs for the proposed frontage road are shown in Table 2. The total project cost, including overhead, is $393,730. The construction cost of $298,280 is based on a typical 32-foot roadway. Although this cost appears to be less than that of Alternative 1, the cost would increase significantly with right-<>f-way acquisition. If it is possible to acquire sufficient right-of-way to construct the frontage road, the City would be responsible for 100% of the right-of-way costs. Another City cost that would involve additional land acquisition is wetland mitigation. Other items not included in the estimate are the impact on Northwestern College entrance roads and utility relocation. The costs for right- of-way and these additional items could easily exceed the frontage road construction cost and would be funded by the City. The alignment affects two wetland areas. The larger of the two wetlands is just south of Old Snelling. The second area is north of Lydia Avenue on Northwestern College property. The permitting requirements for this alternative are the same as discussed with the intersection alternative. There does not appear to be a location in or near the proposed site that would accommodate additional wetland areas. . The frontage road intersection with Lydia Avenue would impact the Northwestern College entrance. The existing brick pillar entryway, wrought-iron fence, and an established grove of trees would be affected by the proposed alignment. 030-1506.....
