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