COMMISSION BUSINESS <br /> <br />Case #1: Lightweight Fill Material Presentation <br /> <br />Steve O'Brien and Jill Brown, from First State Tire Recycling located in East Bethel, handed out <br />some literature on their lightweight fill derived from 'tire chips. Mr. O'Brien stated their <br />company gathers two to three million tires per year, which is about half of the state's tire scraps. <br />He stated that tire chips weigh about 1/5th as much as conventional i511 material, and it can span <br />over soft, spongy soils, heavy wet soils. <br /> <br />Mr. O'Brien stated that some of the engineering benefits include the fact that tire chips have <br />eight times the insulating value of conventional soil, and consequently you end up with a lot less <br />frost penetration below the trail, so you don't have to go back and repair the frost boils that <br />occur. He stated the rubber tire chips also stop the wicking of the moisture to the surface of the <br />trail; therefore, the trail remains dry. <br /> <br />Mr. O'Brien gave some examples of projects 'in Anoka County that used tire chips, and he <br />displayed some photos to the Commission. He stated that Carlton County had done a project <br />using tire chips, and they had estimated their savings at $280,000 by using tire chips over <br />conventional fill. He stated that tire chips cost about 1/10th the price of other lightweight fill, <br />such as geofoam. <br /> <br />.Mr. O'Brien stated that his company would like to do more trail projects, and they would be <br />willing to submit a proposal to donate the material as a subgrade on this fill project in order to <br />use this project to show other interested individuals as a demonstration trail project. <br /> <br />Chair Johns stated she liked the idea of using recycled material. <br /> <br />Case #2: TH 47 Trail Options <br /> <br />Civil Engineer 1~ Linton stated that a resident who lives at 15220 St. Francis Blvd. had requested <br />a trail be created on the west side of TH 47, south of Alpine Drive. Mr. Linton provided a map <br />of existing trails in the area to the Commission. <br /> <br />Chair Johns stated that ultimately they would like to have a trail on both sides. <br /> <br />Civil Engineer II Linton stated he had brought this item forward because Public Works wanted to <br />see how this fit into the overall plan. <br /> <br />Commissioner Ostrum stated it was his opinion that this is something they didn't need to do now, <br />but it is in the plan for the future. He stated he didn't think they wanted to divert the money at <br />this time for the' trail since there is already one on the other side. He stated that this only affects <br />about four or five houses on the west side, and he didn't feel it was a necessitY there. <br /> <br />Park and Recreation Commission/November 18, 2004 <br /> Page 2 of 6 <br /> <br /> <br />
