<br />City of Arden Hills - Comprehensive Plan - DRAFT <br /> <br />Wetlands <br /> <br />Arden Hills has many wetlands of various sizes and types spread <br />throughout the City. The wetlands are an integral part of the natural <br />environment and are important component of healthy lakes, streams, and <br />animal habitat. Development impacts to wetlands are regulated by <br />Federal and State laws. The U.S. Army Corps of Engineers - Saint Paul <br />Office implements the federal wetland laws, and the Minnesota DNR and <br />the Rice Creek Watershed District implement State wetland laws. <br />Alterations to wetlands almost always require a permit, and the City seeks <br />to protect wetlands wherever possible. <br /> <br />10.2.2 Rice Creek Watershed District & Water Quality Management <br /> <br />Arden Hills is located entirely within the Rice Creek Watershed District <br />(RCWD). The RCWD requires permits for land development, site grading, <br />wetland and shoreland alterations, and drainage plans and systems. <br /> <br />Water quality for Lake Josephine, Lake Johanna, Round Lake, and <br />Valentine Lake is monitored by Ramsey County. The RCWD utilizes this <br />data. <br /> <br />The City's Floodplain and Shore land Ordinances govern development <br />activities in areas that contribute storm water runoff to the City's lakes. In <br />addition, the lake use ordinances on Lake Johanna and Lake Josephine <br />help to control erosion and water quality. Unfortunately, water quality has <br />decreased in recent years and additional efforts are needed to maintain <br />and improve water quality. <br /> <br />10.3 Protected SpecieslHabitat <br /> <br />The City is home to at least two species that have a legally protected status, and <br />two habitats that have been identified by the DNR as in need of being protected <br />(MAP). Blanding's Turtles have "threatened" species status in Minnesota, which <br />means that the State has determined that the species is likely to become <br />endangered within the foreseeable future throughout all or a significant portion <br />of its range within Minnesota. While it is outside of the City's regulatory <br />authority, Illinois Tick Trefoil is a rare plant that was identified in the AHATS <br />area. <br /> <br />Both high value habitats are located on the AHATS property outside of the City's <br />regulatory authority. Marsden Lake is a large wetlands complex (wet meadow) <br /> <br />DRAFT <br />4/18/2008 <br /> <br />69 <br />
