<br />CASE # 3 <br /> <br />WETLAND FUNCTIONS & VALUES STUDY <br />By: Chris Anderson, Environmental Coordinator <br /> <br />Background: <br /> <br />As you know, Bolton & Menk has been working on a Surface Water Management Plan for the <br />City. A component of that plan included completing the functions and values study of the 200 <br />plus wetlands that had not been ground-truthed by Westwood Professional Services (WPS). The <br />additional field assessment work was completed in June of 2007.. <br /> <br />The Surface Water Management Plan is very near completion and will likely be presented to City <br />Council, including the updated wetland management classification map, later this month or <br />sometime in November. Since the Environmental Policy Board was instrumental in initiating the <br />functions and values study, Staff wanted to update the Board regarding the completed work. <br /> <br />A total of 349 wetlands were preliminarily inventoried in the National Wetland Inventory (NWI) <br />mapping and by WPS. A total sixty-five (65) of these were determined to be non-wetlands by <br />Minnesota Certified Wetland Delineators (6 by WPS staff and 59 by Bolton & Menk staff). This <br />left a total of 284 wetlands that were placed into one of the four management categories (table <br />includes the numbers determined by WPS after field assessment of 136 wetlands in 2006 for <br />comparative purposes) as follows: <br /> <br />Summary of Wetland Management Classifications for Inventoried Wetlands <br />Wetland Management Final .
