MINUTES OF THE ORONO CITY COUNCIL MEETING Monday, July 25, 2011 7:00 o'clock p.m. • (8. NAVARRE SIDEWALK SEGMENT TO DAKOTA RAIL TRAIL, Continued) land for ponding due to a storm water issue at the intersection. There currently is no storm sewer in that area and that they are not sure exactly where the water drains to. Kellogg stated based on the contours and the information that his office has, back in 2003 the surveyors located a pipe underneath the roadway in this area. Kellogg stated he went out with the Orono Public Works Department and attempted to locate that pipe and it is their feeling the pipe is still there. Kellogg stated the additional survey work would be required to document the location of the trees and their size. They will need to prepare some type of preliminary drawing so they can better evaluate what the impacts would be to each individual property. Bremer asked if Mr. Kellogg has any idea how many easements will be required. Kellogg stated he is hopeful that all that will be required is a temporary construction easement but that it is likely the property owners would like some screening restored. Rahn stated he would like to make the Hennepin County Regional Rail Authority aware of the City's interest to complete this project. Rahn asked what type of retaining wall is being considered. Kellogg indicated it would be a big block wall, which is a gravity wall system. This technology was not available back in 2002. The options looked at back in 2002 for the wall included a sheet pile wall, which • would have conflicted with the utilities, as well as a cast in place wall, which was cost prohibitive. A traditional modular block wall that is seven or eight feet tall would require a geo grid back into the soil, which would have a bigger impact on the property. Kellogg stated the big block wall can be constructed seven feet tall without any reinforcement, which cuts down on the amount of excavation and would cause less disruption to the properties. Rahn asked what the cost was to complete this section back in 2002. Kellogg indicated it was approximately $62,000 to construct the sidewalk from Lyric to Livingston but that the City did not get to a point where there was a wall design done which would have taken it to the next step. Lyric and Livingston has just a couple of minor block walls and the cost was primarily for the concrete and the curb and gutter. Kellogg noted the plans depicted a seven foot wide sidewalk but what was actually constructed was a six foot wide sidewalk. Rahn commented he would like to move forward and speak with Three Rivers on a possible cost sharing agreement. McMillan stated she would prefer not to spend any money on this project until there is a better idea of whether the City will be partnering up with Three Rivers and/or the Hennepin County Regional Railroad Authority. Kellogg asked whether the Council would like them to just complete bullet point one or complete bullet points one and five. • Bremer suggested representatives from Three Rivers and the Hennepin County Regional Railroad be invited to a work session if there is interest on their part in this project.
