Member Stenlund asked about the City's spill response onsite and if the City would want to work with him to develop and modify inlets for oil capture. Mr. Dolan said the City puts stickers on catch basins for education and that there are snakes (a 4" tube to absorb spills) by the fuel pumps and there is clean up powder on hand for spills. There was no public comment. 7. Presentation of Draft Inflow /Infiltration Report Chuck Janske from Bonestroo, the consultant hired by the city, was in attendance to explain the report. Member Vanderwall asked about sump pumps and where the water should be draining. Mr. Janske said the water should be directed to drain out over the lawn and not go directly into the sewer system. Mr. Schwartz said the report would be presented to the City Council at the April 14th meeting. 8. Presentation on Tree Use in Storm Water Best Management Practices Member Neprash gave a presentation on integrating trees with storm water management.

Member Neprash said there isn't an easy answer but there are ways to minimize the potential for problems. 9.
