120 Mr. Johnson explained the pond in the presentation already has a fence around it. 121 Under a lot of circumstances, it is not so much the wetland side, but lakes are a lot 122 deeper so if there is a pond and it does end up getting deeper because the City 123 dredges it, they do not typically go past six to eight feet because a lot of the designs 124 historically have been to dig the pond out to six feet in order for mixing to occur. 125 126 Member Spencer explained on the water heat map, under the bridge at Fairview 127 there is a problem and can become a huge problem during rain events. With the 128 construction that might happen at the mall, is there any consideration of going into 129 that area and doing some work to mitigate the water pooling there or something to 130 get the water away from that area faster. 131 132 Mr. Johnson explained with that model, the City tries to be as proactive as possible. 133 With anything that does happen at Rosedale, they will have to do some sort of 134 stormwater project anyway, there are already six stormwater projects already 135 installed on the property, which does have a big benefit for the City because it is 136 slowing that water down and some of the water from the Fairview/36 corridor can 137 move through there a little faster and not be as impeded as it is now. 138 139 Member Cicha asked if the City is working toward a certain goal for this entire 140 system to be able to handle a twenty year or twenty -five-year storm. 141 142 Mr. Johnson explained the current design standards for storm sewers are the ten- 143 year events. The new storm sewer that goes in will try to meet that. 144 145 Member Misra asked regarding the issues that pertain to the residential 146 contributions, such as glass clippings, she wondered what the primary ways of 147 dealing with them and how effective those ways were. 148 149 Mr. Johnson indicated primarily it is a lot of education and outreach. Staff tries to 150 have communications do the seasonal letters to residents about grass clippings and 151 fertilizers as well as leaves and trying to keep the storm drains clear. The City does 152 have a couple of ordinances that staff can use as well. 153 154 Chair Wozniak asked if there are requirements that private owners of stormwater 155 facilities maintain them. 156 157 Mr. Johnson explained the privately owned stormwater systems are what the City 158 has been targeting over the last few years. Staff has been trying to get information 159 in front of them about what the residents need to do and how to do it. The City has 160 a whole private BMP maintenance program going on with a webpage set up for it. 161 162 Chair Wozniak asked if the City has considered any effort to try and post signs in 163 parks or provide pet waste bags for park users to try and encourage cleaning up pet 164 waste. 165 Page 4 of 6
