127 Ms. Ahlborg asked Ms. Anderson Wenz to talk about Kohlman Lake as it was <br />128 similar to the Como Lake situation that was brought up earlier by one resident. <br />129 <br />130 Ms. Anderson Wenz stated that Kohlman Lake was listed as impaired prior to Lake <br />131 Bennett and stated that the external load has been managed for the past ten years <br />132 and that it is close to being complete. She explained that the management, even <br />133 though good for the waterbody, sometimes still does not satisfy the displeased <br />134 homeowners. <br />135 <br />136 Chair Cihacek questioned how many homeowners present had rain gardens on their <br />137 property and asked how many people are picking up their pet and yard waste <br />138 consistently. <br />139 <br />140 Many residents replied yes, they do these things. <br />141 <br />142 Ms. Anderson Wenz stated that the watershed offers afeature on the website where <br />143 residents can see what district they are in and encouraged residents to use that to <br />144 gain a better understanding of where the runoff water is coming from. <br />145 <br />146 Environmental Specialist Johnson stated that aerators can be ran and teis might be <br />147 a good option for Frog Pond. He stated that he was skeptical of the use of any <br />148 chemicals to treat the water. <br />149 <br />150 Chair Cihacek questioned if there were other odor control options for Frog Pond. <br />151 <br />152 Mr. Johnson replied there were none that he was aware of. <br />153 <br />154 Chair Cihacek asked Mr. Johnson to look into that and report back to the <br />155 commission. <br />156 <br />157 Member Misra stated the presentation indicated that impervious services are the <br />158 largest contributor and asked that Ms. Anderson Wenz further explain this aspect. <br />159 <br />160 Ms. Anderson Wenz stated that all the impervious surfaces greatly increase the <br />161 mobility of water and help it move around rather than filtrate into the ground where <br />162 it gets cleaned. <br />163 <br />164 Member Misra questioned how the impervious surface is being addressed through <br />165 the various agencies. <br />166 <br />167 Mr. Johnson stated the programs and permitting aim to reduce the amount of <br />168 impervious surface or at least incorporate mitigation efforts to address the runoff <br />169 created by added impervious surface. <br />170 <br />171 Member Misra asked if design was considered and questioned whether trails and <br />172 sidewalks could be designed to use less impervious materials. <br />
