Deb Bloom introduced the Impaired Water Review process done by the City to monitor what has changed in the water and verify it complies with the Total Maximum Daily Load Limits. Member Stenlund asked what size of water body requires this type of review. Duane Schwartz answered with information on the distinction between a pond and a lake. Member Stenlund asked about Central Park Frisbee golf area is being trampled and eroded by dirt discharge. Deb Bloom recommended that Parks department could inspect this area to see what can be done. 8. 2008 Storm Water Report Deb Bloom reported on Storm Water items that were completed throughout the year. The report covers problem area updates, 2008 new problem areas, 2008 redevelopment projects and other drainage concerns. There were six different problem areas that were identified. The first area was the AvonBrenner area where water is about three feet deep in some intersections. The recommended 2009 action is to work with the bank to acquire the property that is located on Millwood and Brenner. Member Felice asked for an explanation of a catch basin. Duane Schwartz gave an explanation on how the water goes into a catch basin then into pipes which takes the water to lakes or ponds. Another area is the St. Rose of Lima area off of Hamline. The only solution for this area was to convert a Keller Mayflower Park to a pond due to backed up water. South Owasso Boulevard was another area which was completed in 2006. The third problem area is the area around Gluck Pond floods after a large storm which produces six or more inches of water. Several solutions have been discussed but nothing has been decided yet. Member Vanderwall asked about the drainage problem near Rosedale shopping center. Duane Schwartz and Deb Bloom answered question by explaining how the pipes under Fairview are small and the area would need to be redeveloped. Another problem area is the Walsh Lake watershed. The City has been working with property owners in this area by installing rain gardens and expansion of existing ponds and wetlands. Those projects are proposed to be done this summer. This includes an expansion of the ponds near Midlands Apartments. No new problem areas were identified so no new areas were added to the list. 2008 redevelopment projects include the rain gardens that were installed in 2008, Gold Eagle area reducing runoff, Northwestern College put in an underground system and rain gardens, Rainbow Foods put in an underground chamber system, Chianti Grill installed an underground system, D'Amico and Sons by Perkins put in an underground system, Midland Grove condominiums addressed drainage problems by installing a courtyard rain garden, TCF bank at Pascal installed a new infiltration system and Bennett Lake shore line improvement project. 4
