Mr. Bruce Wesiby June 19, 2015 Page 2 2. Page 6, item 7 of the Ramsey Plan states; The wetland buffers recommended in the Wetland Function assessment were approved by City Council when the 2008 SWMP was approved. Further review of the buffers by the City Council resulted in a policy to delay the implementation of the wetland buffer recommendations. • This statement is also mentioned in several places throughout the Ramsey Plan. Wetland Protection Standards for the LRRWMO are outlined in Appendix G of the LRRWMO WMP. The Ramsey Plan must specifically identify these standards, how the City will be implementing these standards and any wetland requirements, such as buffers, that the City will be implementing through ordinance. • 3. Page 14, Item B of the Ramsey Plan states; Figure 4 shows the 10-year capture zone (Well Head protection Area, WHPA) as well as the Drinking Water Supply Management Area (DWSMA) for the seven municipal drinking water wells in Ramsey. Storm water infiltration will not he allowed inside these zones. Page 34, Item D of the Ramsey Plan states (last sentence); City Policy adopted in conjunction with infiltration requirements of the LRRWMO Third Generation Plan permits infiltration in areas within the Drinking Water Supply Area (DWSMA), so long as it is not also within the 10-year capture zone. • These two statement appear to somewhat be in conflict with each other. ▪ The Ramsey Plan needs to address how volume retention requirement is to be complied with in areas such as the DWSMA or in areas that are non -conducive for infiltration. 4. Page 16, Item #2 of the Ramsey Plan states; The bounce from the normal water level to the high water level does not exceed two feet. • It is recommended that this comment be replaced with, The impacts of storm water from new development discharging into a wetland will he determined through a Minnesota Routine Assessment Methodology (MnRAM) assessment of the wetland. A MnRAM provides a quantitative and qualitative assessment of the impacts that storm water has and will have on a wetland. 5. Page 18, Table 16; of the Ramsey Plan. It is recommended that the Design Infiltration Rates in the Minnesota Storm Water Manual, as amended, be used and referenced rather than the information from Urban Hydrology for Small Watersheds, (SCS, 1986). 6, Page 19, Item #11 of the Ramsey Plan : Unique Features and Scenic Areas; The City Codes referenced, Chapter/Section 177, must comply with the revised MDNR's Wild and Scenic River Management requirements.
