and increasing levels of storm water nutrient pollution. This spiral effect results in <br />statistically even greater levels of pollution than the original sewage "problem" might <br />have been. For example, Eugene Hickok's 1973 Storm Water Impact Statement <br />which identifies up to ten times more phosphorus alone from urban storm water <br />runoff than from Orono's existing rural land use. <br />One need only to look to the case example of Lake Calhoun in Minneapolis. (?)There <br />has never been a drop of sewage effluent running into Calhoun, but the lake is <br />suffering (?) severe pollution from high levels of nutrients contained in the storm <br />water runoff from the densely developed watershed. Storm water nutrient pollution <br />from the urban runoff overwhelms the natural life system of the lake and results in <br />accelerated eutrophication. <br />The cost of solving this problem, either filtering or rerouting the storm water, has <br />consistently been judged too expensive for Calhoun. The cost of the same solutions <br />on the 50 times larger Minnetonka is inconceivable. Thus the recommendation of <br />many studies as already incorporated in MPCA and MnDNR policy is that lakeshore <br />density be limited and that the natural system of wetlands and marshes be forever <br />protected and preserved as the only practical, economic method of filtering nutrients <br />from storm water runoff. <br />(ADD A PARAGRAPH DISCUSSING THE ANTICIPATED HIGH COSTS OF <br />CONSTRUCTED STORMWATER PONDING SYSTEMS, AND THE IMPORTANCE <br />OF NOT RELYING ON THEM AS A SOLUTION TO ALLOW HIGHER DENSITY <br />DEVELOPMENT) <br />THL URBANIZATIO.N SPIRAL <br />Illustrates the Deselopment Paradox that faces <br />Orono if municipal ser\ ices are extended into rural areas. <br />CMP 3B-5
