Arena Commission Minutes Page 4 June 23,2016 Commissioner Westgaard says the preliminary information, estimated the cost to be $1.5 Million to correct the soils at Lions Park. The architect bumped that figure to $4.5 million. Now the architect has adjusted and reevaluated and two weeks ago it went up to $7.6 million. With the figures changing so much,is it safe to accept the $1.2 million estimate to replace the softball complex or the $30—33 Million figure for a new facility?He adds it isn't fiscally responsible to present a figure to the voters and ultimately be that far off. Commissioner Madsen notes that Stillwater has two rinks and an inflatable dome, and asks if that is new? Commissioner Ballenger states one of the sheets and the dome aren't very old. Commissioner Westgaard adds we should be leaning on other cities that have arenas and domes and have done these things more recently to give us an idea on costs. However the Public Works facility was the same way. What we budgeted for, and what it ultimately came in at was much more favorable. If the school district is seeing the same thing with their project,it is good,but there is no guarantee. He adds, once the City has the final reports for the soil borings,we may be able to have conversations with local business owners to see if the material that would be dug up just needs to be taken away, or would it be usable for something? If that's the case,what is that cost really going to look like. Arena Manager Czech notes, that the City Engineer has calls into people regarding that. Commissioner Ballenger notes that the sports center was built on peat. Commissioner Westgaard says the City has talked to the boys and girl's club and Elk River Machine that are located on the same parcel of land. Target in Otsego sits on 72"inches of soil correction, so there is some local stuff going on with peat contractors involved. The contractor is concerned with this location because of it's large footprint and the ice sheets that cannot have movement. Arena Manager Czech reviews the drafts and notes about the soil boring. There were seven drill sites,with some areas being better than others in terms of building- the final report should be received by next Wednesday. Commissioner Westgaard asks how it works if the top layers are ok,but farther down if it is clay or peat do they take the top off,remove the "bad layers" and then put the good stuff back on top? Czech notes from his understanding in talking with the City Engineer,anywhere it is noted there is organic clay or peat,is where it would need to be changed out. In general,he estimates it to be an average of 10.5' of material. He also noted when doing borings,you are just getting a picture of the area where the borings are done. • Ten feet either way could be a totally different story. POWERED Br NATURE
