<br />I <br />I. <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I. <br />I <br />I <br />I <br />I <br />I <br />I <br />I. <br />I <br />I <br /> <br />located at the western end of the neighborhood and would treat specific portions <br />of the neighborhood as described below: <br /> <br />Proposed Pond A is located between Hamline Avenue and Highway 51 and <br />south of Ingerson Road. This pond would treat storm water from Hamline <br />A venue and Ingerson Road west of Pernwood Street which generally drains <br />overland to Lake Josephine, the MnDOT ditches or ponds on Ingerson Road until <br />it evaporates or seeps into the ground. The pond would be approximately 0.60 <br />acres in size and be a maximum of 10 feet deep with a permanent pool visible <br />except for extremely dry periods. The proposed site includes land owned by <br />MnDOT and the City of Arden Hills. A significant stand of trees exists <br />throughout the site especially adjacent to HamJine A venue and many of those <br />trees may need to be removed in order to allow for the grading of the pond. The <br />pond shape will be manipulated to minimize any impacts to existing trees in the <br />area. <br /> <br />Proposed Pond B is located in the vicinity of Hamline A venue north of Ingerson <br />and therefor can only be constructed if Hamline A venue is vacated as is proposed <br />above. This pond would treat storm water from Tiller Lane, Cannon Avenue and <br />Dunlap Street which currently drain into the wetland located between Ingerson <br />Road and Tiller Lane. The pond would be approximately 0.5 acres in size and be <br />a maximum of 10 feet deep with a permanent pool visible except for extremely <br />dry periods. The construction of the pond would require coordination with <br />MnDOT and the Rice Creek Watershed. The proposed site includes land owned <br />by MnDOT and the City of Arden Hills. A few trees exist throughout the site and <br />some of those trees would need to be removed in order to allow for the grading of <br />the pond however the loss of screening would be less severe than the screening <br />lost to construct Pond A. If Pond B is not constructed, the runoff is proposed to <br />continue to drain directly to the wetland however a grit chamber should be <br />considered to provide some level of water quality treatment. <br /> <br />The Fernwood Court channel is located between Ingerson Court and Pemwood <br />Court. The existing channel area does not contain enough land to construct a <br />pond however, the project includes the construction of a weir and some minor <br />ditch excavation and clearing to provide as much water quality enhancement as <br />possible given the existing topographical and property constraints. Drainage <br />routed through the Pernwood Court Channel would continue to drain ultimately to <br />Lake Josephine. <br /> <br />5 <br />
