Regular City Council Meeting Monday, July 25, 2016 Page 20 cleaning up these contaminated sites, whether lightly or heavily contaminated concrete, and for that material to be crushed on site at the risk of city residents, hotel patrons, or workers on the project, and potentially stored on site for up to two years, she also found of grave concern. Since this site was so close to the freeway, Councilmember McGehee opined there was no reason, other than addi- tional cost to the contractor and/or developer, the material could easily be hauled off site and clean Class 5 material be hauled in to prepare the site for building. If there was an immediate use eminent for the site and some real oversight of the ac- tual contamination of these materials, Councilmember McGehee stated she may be persuaded, but since there was apparently no use at all of those materials on this site, and the unknown nature of whether they will eventually be hauled off site of not, she didn't see what the city was gaining if allowing the crushing op- eration on site other than having a shove-ready and clean site. Councilmember McGehee further noted this site wasn't out in the middle of nowhere but of poten- tial risk for new tenants on the lake and others around the site; and consisted of known contaminated materials as evidenced by other excavations and soil bor- ings, making it a matter of how much it was contaminated. Councilmember McGehee opined if left up to the contractor to make the determination, which she found to be an inadequate check, it was incumbent upon the municipality to as- sume responsibility for activities or monitoring of those activities in a scientific way to protect the quality of the park and health of its residents and neighbors, as well as patrons of its public amenities. Councilmember Laliberte sought clarification on the 30-day period intent. While unsure if they had yet to be applied for pending approval of the IU by the City Council, City Manager Trudgeon noted that was the anticipated timeframe for the developer/contractor to obtain permit approvals from the state and county with that timeframe yet to be determined depending on the processes of those agencies. Councilmember McGehee asked Mr. Vollhaber for a cost comparison for hauling the materials off sight versus crushing and storing them on site. Mr. Vollhaber responded that it would depend on the market for the materials at the time they became available; but anticipated it would be in the range of $40,000 to $60,000 in savings to crush them on site and re-use them in the local area. At the request of Councilmember McGehee as to whether the reason for seeking the IU to crush on site was solely a financial decision, Mr. Vollhaber responded that it was that partly as well as a wise use of recycled materials in the area in which they were generated rather than trucking them off site. Mr. Vollhaber ad- vised that the intent was to start crushing operations this fall as soon as permits are obtained.
