MINUTES <br />CITY COUNCIL <br />FEBRUARY 23, 1994 <br />Olson estimated the street life at 10 years for the <br />mill and overlay option and 20 years for the full depth <br />reclamation. Olson pointed out that there is a high <br />water table and clay soils in the area, as well as <br />settlements that have occurred in the utility trenches, <br />thus causing damage to the street and the need for <br />restoration. Olson pointed out that more base is <br />involved in the full depth reclamation, therefore, the <br />expected life of the street increases. <br />The Administrator reported that the surface of the <br />street is not in bad shape, however, break-up is <br />occurring along the curb and gutter and around the <br />culverts. The restoration of these streets is needed <br />so that the integrity of the streets is not <br />jeopardized. The Administrator stated that a mill and <br />overlay of these streets along with some drainage <br />improvements will protect the integrity of the streets. <br />The Administrator stated that given the condition of <br />these streets he was not sure a full depth reclamation <br />was warranted. <br />The Public Works Superintendent indicated that another <br />option would be to install fabric between the base and <br />blacktop, however, the costs of doinq so might be too <br />high. The Superintendent pointed out that there is not <br />much crown on these two streets, therefore the street <br />is not draining properly. Also the street has settled <br />and it is breaking up along the curb. The <br />Superintendent felt a grind and overlay would address <br />these problems well. The Superintendent also pointed <br />out that the utility pipes under the streets are moving <br />during the freeze and thaw cycles, thus adding to the <br />problem. The University would like to install some <br />instruments under the street to monitor and study these <br />movements. <br />Olson stated that with a mill and overlay improvement <br />and proper maintenance he would fully expect these <br />streets to last longer than the 10 years he estimates. <br />Morelan pointed out that the cost for a 20 year <br />improvement is not much greater than the cost of the 10 <br />year option. Morelan suggested that given this fact <br />perhaps the 20 year option is the way to go. <br />Pedersen pointed out that the difference is about $400 <br />7 <br />
