A full list of both active <br />and inactive MPCA listed pollutant sources in Arden Hills can be found in Appendix E. <br /> <br />RCWD’s Southwest Urban Lakes Study developed Lake Management Action Plans to summarize <br />lake characteristics and existing lake data, provide a diagnostic assessment of the data, <br />summarize public input, identify water quality issues, and recommend remedial strategies on a <br />lake-watershed basis. These Lake Management Action Plans will be used as guidance for retrofit <br />water quality improvements to address TMDL goals. An opportunity to improve resource <br />management exists with the redevelopment of the TCAAP site, which requires an environmental <br />overhaul due to contaminated soils and groundwater. With the office, retail, and housing <br />redevelopment, the natural resources are brought back into compliance. The master development <br />concept incorporates more than 50 acres of green space and connections to parks and trails. <br /> <br />The MPCA and DNR also maintain lake information databases. The MPCA database is located <br />at http://www.pca.state.mn.us under Water > Water Types and Programs > Surface Water > <br />Dr <br />a <br />f <br />t <br /> <br />11 <br />/ <br />2 <br />0 <br />/ <br />2 <br />0 <br />1 <br />7
