Any activities exempted from the provisions of the WCA are also exempted from the <br />requirements of this Chapter, insofar as they relate to the WCA (Minn. Rules 8420.0122). <br />Alt wetlands, including those governed by the Department of Natural Resources, are <br />covered by the other provisions of this Chapter. <br /> <br /> Subd. 7. The City has also found that it is in the best interest of the general health <br />and welfare of the City to achieve no net loss of wetlands with/n the community. It is the <br />intent of' this Chapter to avoid or minimize the alteration and destruction of wetlands <br />where possible. When wetlands are altered or destroyed, mitigation must be provided to <br />recreate the functions and values of the lost wetland. <br /> <br /> Subd. 8. it is the intent of this Chapter to develop a methodology for determining <br />the relative value of the various wetland types within the City. By use of a values and ' <br />measures system, various buffering scenarios will be defined dependent upon their value <br />as measured (eg. More valued wetlands will have more stringent buffering guidelines). <br /> <br /> Subd. 9. Vegetative buffer strips meliorate and filter runoffand discharge into <br />wetlands. Wetlands are instrumental in maintaining and improving both water quantity <br />and quality for aquifer recharge. In addition to 'the mechanical and physical function of <br />impeding sediment ran off and transport, buffer strip and wetland vegetation are <br />indicators of the biological functioning that serves to metabolize or sequester nutrients as <br />well as contaminants and sediment. The ability to support microbial life, <br />macroinvcrtebrates, and common wildlife is a proximate indicator of the value and <br />quality ('health') of the wetlands and their associated buffer region. In turn, the water <br />quality desired for human use and human health is the functional result ofbi01ogical <br />~rocesscs in wetlands and associated buffers. <br /> <br /> Protection and enhancement of vegetation in the buffers during establishment <br />increases their buffering capacity for the wetlands. Biotic baselines are integral to <br />maintaining and evaluating the functional health of the inventoried wetlands. Periodic <br />monitoring and peridodic review of biologic functions can be a means of evaluating <br />.success of the technical guidelines and implementation in single wetlands, complexes or <br />stream watersheds. Review of existing data from within the City can help establish <br />baselines and expectations. <br /> <br /> S ubd. I 0. It is the intent of this Chapter to place a higher level of priority,to <br />protect and preserve larger, connected wetland complexes of high ecological integrity <br />than smaller, isolated wetlands that have already incurred substantial eutrophication and <br />contamination. <br /> <br />9.26.02 Purpose and Implementation. <br /> <br />~amsey Wetland Protection Ordinance - April 2005 Draft (showing suggested PC revisions) <br />Page 2 of 8 <br /> <br />71 <br /> <br /> <br />
