C(D) <br /> EXAMPLES OF WETLAND AND FLOODPLAIN EXPERIENCE <br /> Wetland Management Plan,City of Ramsey,Minnesota <br /> The City of Ramsey's Wetland Management Plan included field review and evaluation of all of the City's <br /> wetlands using MnRAM functional assessment software to rank each wetland in low,moderate,high and <br /> exceptional categories based on the MnRAM functional index score.These categories were mapped and <br /> included in the Ramsey Comprehensive Wetland Management Plan. <br /> Bolton&Menk,Inc. assisted the City of Ramsey in developing wetland protection rules that were <br /> incorporated into ordinance recommendations.The Plan and its figures,maps and tables were made GID- <br /> ready for inclusion into the City's GIS system.The Plan was also distributed to all of the potential TEP <br /> members,including the area watershed districts, for review and comment prior to presenting the Plan to <br /> the City Council and ultimately to the public in a hearing. <br /> Floodplain DFIRM Remapping,City of Lake Crystal,Minnesota <br /> The City of Lake Crystal,MN recently received updated preliminary Digital Flood Insurance Rate Maps <br /> (DFIRM)along with flood mapping updates in Blue Earth County.During this study,FEMA chose to <br /> remap County Ditch(CD)56, which flows directly through a residential portion of town.Bolton&Menk, <br /> Inc. was hired to review the preliminary flood mapping because several properties were added to the <br /> FEMA regulated floodplain that were not included in previous maps.The hydraulic modeling performed <br /> by FEMA"s mapping partner was reviewed,where it was discovered that several key hydraulic <br /> conveyance features through town were neglected in the hydraulic models,thereby artifically increasing <br /> peak flood elevations and extending the floodplain boundary. <br /> The City of Lake Crystal hired Bolton&Menk,Inc.to remap all of its floodplain maps and produce <br /> hydraulic models and documents according to FEMA's Guidelines and Specifications for Flood Hazard <br /> Mapping Partners.Additional survey data, along with available LiDAR topographic data,was obtained <br /> where neceassry and the hydraulic models and DFIRM maps were redeveloped using the more accurate <br /> data.The new maps and study underwent rigorous QA/QC analysis including the use of the CHECK- <br /> RAS program to verify the acceptability of the revised maps. <br /> The resultant maps and Flood Insurance Study removed a significant amount of properties from the <br /> proposed floodplain and established reliable 100-year flood(1%event)elevations that can be used to <br /> properly manage the floodway.The data and supporting report documents were submitted to FEMA <br /> during Blue Earth County's comment period where the new modeling and maps were approved and <br /> accepted by FEMA.Also,the modeling and mapping was determined to be at a high enough level of <br /> detail that the maps were adopted as Zone AE with documented base flood elevations as opposed to the <br /> previously accepted Zone A maps.Upon completion of the project and FEMA approval,the City of Lake <br /> Crystal received reliable and accurate flood information. <br /> FEMA Digital Flood Insurance Rate Map(DFIRM)Study,Meeker County,Minnesota <br /> Meeker County received a grant from the Minnesota Department of Natural Resources to remap several <br /> of its streams using the HEC-RAS hydraulic modeling software.Bolton&Menk,Inc.was hired to work <br /> with Meeker County Survey Data and available contour mapping to generate a series of hydaulic models <br /> as well as utilize HEC-GeoRAS to delineate the FEMA Zone A floodplain. Bolton&Menk followed <br /> FEMA's Guidelines and Specifications for FLood Hazard Mapping Partners to produce highly accurate <br /> flood modeling data that met FEMA's rigorous requirements. <br /> N:\PROPOSALS\SSmvey\Bumsville\2012\Topo\Arden Hills 2013\Arden Hills 2013 PMP.doc <br />
