Dave Ahrens, P.E. City Engineer City of Lino Lakes April 18, 1996 Page 2 Option C: Option C has been deemed a non-viable option. This is due to the fact that the total project cost of this option is the highest of the six discussed. This option also does not provide for the installation of a signal in the foreseeable future. A figure depicting Option C has been attached to this memo. Option D: Option D provides for a separate road serving the school site that would follow the same alignment as options A and B, but would not provide a connection to existing Elm Street. The proposed roadway would cul-de-sac immediately south of the southern=most access to the school, or near the north end of the ball field proposed on the school site. This option does provide for the least impact to the neighborhood south of Elm Street, however, this option does not provide for the installation of a signal in the foreseeable future. This option does provide for on-site traffic patterns similar to options A and B. There are three primary concerns with this option that make it less desirable than options A and B. The first concern is that this option does not provide for a signal at the intersection with Trunk Highway 49. The second concern is that it does not provide convenient access to the school for residents living north and west of Trunk Highway 49 and south of Elm Street. These individuals would be required to access the school from Trunk Highway 49. Options A and B provide for access to the school from the realigned Elm Street. The third concern with this option is that a large amount of the area within the school district that is being served by the school will be accessing the school from the south. This traffic would be required to make a left-hand turn from Trunk Highway 49 on to the proposed service road to the school. It is our opinion that this left-hand turn would be a dangerous movement and could possibly expose the City to some liability issues regarding traffic accidents at this intersection if this option were selected by City Council. Option E: Option E has been determined to be un -viable due to the impacts on the residential neighborhood south of Elm Street. This is due to the anticipated intensity of traffic at the intersection of Elm Street and existing Grey Heron Drive. A figure depicting this option has been attached for your reference.
