<br />City of Arden Hills - Comprehensive Plan - DRAFT <br /> <br /> Listed on the Potential to <br />lake No Data 303( d) list of become <br /> lrlllaired waters impaired <br />Johanna~ X <br />Josephine~ X <br />Karth X <br />Little Johanna X <br />Marsden X <br />Round X <br />Sunfish X <br />Valentine X <br />"Listed on the 303(d) lis\ of impaired waters for mercury <br /> <br />The 303(d) list is part of the federal Clean Water Act, which requires states to <br />adopt water quality standards to protect waters from pollution. <br /> <br />10.5.4 Priority Areas <br /> <br />Area 1 - This area contains a relatively diverse assemblage of upland and <br />wetland communities connecting Lake Johanna and Farrel's Lake. Upland <br />community types in this area include aspen forest, lowland hardwood forest, oak <br />woodland, and mesic prairie. Wetland community types in this area include <br />willow swamp, mixed emergent marsh, and cattail marsh. The majority of these <br />communities were given a "medium" ranking in the natural resource assessment. <br />There are also several potential opportunities for wetland restoration within this <br />area, both hydrologic and vegetation. Lake Johanna has the potential to become <br />impaired due to excess nutrients. <br /> <br />Area 2 - This area contains areas a mosaic of upland and wetland community <br />types surrounding Rice Creek. Community types include forest, woodland, and <br />emergent marsh. The majority of these communities were given a "medium" <br />ranking in the natural resource assessment. The portion of Rice Creek within the <br />City of Arden Hills is currently on the 303( d) list of impaired waters. A portion of <br />this area near Interstate 35W on the west side of Rice Creek is included in the <br />TCAAP redevelopment plans. <br /> <br />Area 3 - This area contains areas of forest, woodland, and emergent marsh <br />surrounding Marsden Lake. All of the lake's shoreline is in natural vegetation. <br />This complex of natural areas is unique because of its large size and lack of <br />fragmentation. The majority of these areas were given a "medium" ranking in the <br />natural resource assessment. Marsden Lake does not have sufficient water <br />quality information to determine its potential for water quality impairment due to <br />excess nutrients. <br /> <br />DRAFT <br />4/18/2008 <br /> <br />74 <br />
