Mr. Bruce Westby <br />June 19, 2015 <br />Page 4 <br />16. Page 43, Goal 7 - Wetlands of the Ramsey Plan; A policy should be provided that the LRRWMO is <br />the Local' Governmental Unit (LGU) administering the requirements of the Wetland Conservation <br />Act (WCA) in Ramsey. <br />17 Page 43, Policy 7.1 of the Ramsey Plan states; Use and Function of all wetlands greater than 1i4 acre <br />in size has been determined as port of the 2008 SWMP preparation. <br />• In other Sections of the Ramsey Plan it has been stated that the Use and Function of the <br />wetland has been prepared but will not be used at this time This needs to be clarified and <br />describe how the requirements of Appendix G - Wetland Protection Standards in the <br />LRRWMO WMP are to be complied with. <br />18. Page 46, Policy 12.7 of the Ramsey Plan states; The City will perform regular wet storage volume <br />surveys of its storm water quality ponds on a 10-year rotating basis, <br />• Is this consistent with the requirements of the City MS4 permit requirements? <br />General Comments <br />1. The figures for the various Study Areas show "Potential Threat to Structures" designation. A table or <br />some form of reference to the structure location (address), low floor elevation and flood elevation <br />would be useful information in the Ramsey Plan. <br />2, The flood elevations and discharges shown in the tables are listed to the hundredth (0.01) of a foot <br />and hundredth (0.01) of a cubic foot per second (c.f.s.), respectively. Because of the numerous <br />assumptions and variables used in these calculations, it is recommended that flood elevations be <br />shown to the whole foot (no less than a tenth of a foot - 0.1) and discharges be shown to the whole <br />c.f.s (no less than a tenth of a cf.s. - 0.1). <br />Thank -you for the opportunity of providing our review comments regarding the Local Surface Water <br />Management Plan for the city of Ramsey submitted to the LRRWMO in accordance with MN Rule <br />8410.016. <br />If you have any questions or request further clarification of our comments, please contact Todd Naas, <br />LRRWMO Board Chairman or me at 952-832-2857, bobermeverObarr.com. <br />Sincerely, <br />Robert C.
