alleviate these conditions. He reviewed the following options to consider of upgrading <br />the current road: <br /> <br />Calcium Chloride. One option for addressing dust control is the application of a calcium <br />chloride. This chemical draws moisture from the air which is drawn into the road material <br />and provides effective dust control. One application provides adequate dust control for <br />the season. The moisture in the road bed also keeps the surface firm and minimizes <br />washboarding and the need for regrading. The cost of an outside contractor to provide the <br />chemical application is $1,650. <br /> <br />Sealcoating. A second option for providing dust control which also provides a hard <br />surface would be to sealcoat the existing class 5 roadway. This method is similar to that <br />used for the sealcoating of the City's bituminous pavement, however it also includes the <br />application ora bituminous emulsion primer which is incorporated into the surface prior <br />to the sealcoating. The resulting hard surface is thin bituminous crust which has a <br />durability that is highly dependant on the quality of the underlying base. A good quality <br />base will allow this surface to provide years of service. The cost of an outside contractor <br />to provide the materials and equipment for the primer and the sealcoating is $4,100. <br /> <br />Wear lift bituminous coarse. A third option would be the placement of a two inch lift of <br />bituminous wear course over the existing class 5 graded road. This option is most similar <br />to the standard City road specification except that it eliminates the two inch bituminous <br />base course. It should be quite durable and would tolerate weak base sections much better <br />than the sealcoating. The cost of this work is $15,200. <br /> <br />City Engineer Jankowski advised the recommendation among the three options presented <br />above is highly dependant upon the length of time this park road will be in use. Utilizing <br />the assumption that the area adjacent to this roadway will develop in three to five years, it <br />seems safe to be able to eliminate the bituminous wear course from consideration as it <br />would not provide a reasonable payback. <br /> <br />Chairperson Elvig inquired about the possible timeframe for the development next to <br />Elmcrest Park. <br /> <br />John Peterson of Oak~vood Land Development informed the Committee that Oak~vood <br />Land Development has purchased all three of the properties in this cluster and will be <br />ready to proceed as soon as sewer and water is available. He is planning a timeframe of <br />two to three years for development to begin. <br /> <br />Motion by Councilmember Cook, seconded by Chairperson Elvig, to recommend to City <br />Council that the Elmcrest Park road be improved by sealcoating and that the funding for <br />this work come from the annual parks budget. <br /> <br />Motion carried. Voting Yes: Chairperson Elvig and Councilmember Cook. Voting No: <br />None. Absent: Councilmember Olson. <br /> <br />Public Works Committee / July 19, 2005 <br /> Page 6 of 11 <br /> <br /> <br />
