Mounds View City Council regular Meeting Page Four July 13, 1992 Peter Sabee stated that the key issues had to do with location of wetland boundary, criteria for setbacks, lot width and lot area. Mr. Sabee explained the change in wetland boundary and how it was derived. Mr. Sabee also stated that the lot size and area are in compliance. Lot area came in to compliance by widening lots and bringing the lot lines further into the wetland. Councilmember Rickaby asked what had changed in the wetland boundary. Mr. Sabee stated that basically the change was the method used to delineate the wetland boundary. Mr. Sabee explained that another concern was the method used for calculating water quality enhancement. Many communities use the Walker method. This method works by providing storm water storage to settle sediment particles from storm water runoff. The more particles settled greater value of water quality. Wildlife enhancement initial concerns are the shape and topography of the ponds. Irregular sides and irregular bottom contours of ponds are better. Councilmember Rickaby asked if on this proposal there were fewer lots, but greater proposed development area. Mr. Sabee responded that there was probably more square footage in lots. Councilmember Rickaby asked about a ditch in the proposal. Mr. Roos described the location of the ditch, where it ran and the location of the ponds. Councilmember Rickaby asked what the effects on the flood plain would be when one is preventing the lowering of the ground water level. Mr. Roos stated that there would be no effect on water flow characteristics. Councilmember Wuori asked if this development was changing the 100' setback on the south and east sides. Are the setbacks the same as before or do they extend further. Mr. Roos stated that the south side doesn't change. on the east there will be a change in the wetland zone at the south one third. There will be less on the west side. Homes on the east side encroach further on the wetland zone than before . Paul Harrington, City Planner stated that houses that are currently in place will remain as they are. Councilmember Wuori also stated that it was her understanding that the persons purchasing this property are purchasing a portion of wetland that cannot be used and could not be maintained as a garden or part of their ~ard.
