some cases, as with this site, there were site constraints defining what could be <br /> accomplished. <br /> At the request of Member Seigler, Mr. Johnson stated that in this pond, the <br /> management involved water evaporation versus infiltration due to the heavy soils <br /> in this area. <br /> Member Lenz questioned if this created a breeding ground for mosquitoes. <br /> Mr. Johnson noted that there was lots of open water in Roseville, but since insects <br /> fed off mosquitoes, this situation was part of the overall ecosystem, and not like <br /> having standing water in a tire in a yard. <br /> With the city changes in ice control methods over time, Member Wozniak asked <br /> if there were restrictions for private property owners as well. <br /> Mr. Johnson advised that private property owners could use their choice for <br /> keeping their parking lots safe, noting that they were typically more concerned <br /> with liability and safety issues of their clientele rather than whether or not they <br /> were using too much sand or salt. <br /> Mr. Freihammer noted that a lot had changed over time with many of those <br /> businesses using more salt versus sand, as they have found it more effective and <br /> causing less tracking into their establishments. <br /> Chair Cihacek noted this caused a whole different problem, that of nitrates <br /> loading in water bodies; and should become part of the city's efforts going <br /> forward for business and resident choices in ice control. <br /> Mr. Johnson confirmed that, as part of the MS4 reporting, the city's intent for one <br /> educational piece was to alert citizens and business owners to the effects of what <br /> they used on their lots and impacts to local water resources. By making them <br /> aware of it and the subsequent cost to them, Mr. Johnson expressed his hope that <br /> this would prompt them to use less or use these materials more wisely once, <br /> especially if and when a business owner found this was cutting into their profits <br /> through additional utility fees and infrastructure costs. With the significant <br /> number of private businesses and their stormwater impacts, Mr. Johnson advised <br /> that staff was very interested in educating them. Mr. Johnson noted that these <br /> efforts were ongoing and frequent in various communication efforts, with Public <br /> Works Department staff continually bringing things to the City's Communication <br /> Department for inclusion in email blasts and city newsletters rather than the cost <br /> for doing so specifically to-date in sending individual mailings. Mr. Johnson <br /> advised that the intent was to hopefully reach a broader scale. <br /> Page 10 of 17 <br />
