I I I I I I I I Mr. Steve Jankows rki, City Engineer City of Ramsey .. 15153 Nowthen Boglevard N.W. P,_amsey, MN 55303 Dear Mr. Jmkowsld: Proposed Sunwoo~l Drive Crossing, DNR Permit Application No- 94-6209, Public ~raters Wetlands Z-114P ~ 2-673'W Tiffs letter is to adV!S~ e you on our progress relative to the City's application to cross public waters wetlan~ wifh Sunw¢od Drive. The cross/rog proposal as it now stands includes approximately 100 linear feet of fill an~ a 100 foot bridge span across the main portion of wetland 2-114, a double 84" arch pipe at the nar~ ow cross/ng of2-114P, and a 100 foot bridge span across basirt 2-673W. At this time the D~partment of Natural Resources is prepared to issue a permit for the above ~-eferenced crossingsiifthe City can adequately compensate for lost wetland values. Thc previously proposed wetland e~cavation wSl not constitute adequate mitigation for the effects of tile lxoposed road project. We have, however, identified an option that would be acceptable to the Departmen[ and allow the road eross/ngs to proceed. We suggest partial restoration ofl'dstoric water levels in wetland 2-114P through one or more ditch blocks, The detailed design of any ditch block structure(s) will have to be worked out through a series of site visits, ~urwey/ng the potmtial locations, modeling the impacts of the potential blocks on water s~f~e elevations and flows,, and infommtional meetings for the affected landowners. The DNR. Div/sion of Waters is prepared to assist the c/ty in completing this design process. Since this has the pptential to be a very pos/five change to the wetland complex, ..~e Depm-tment is volli~ to work co ~opMatively with the City by supplying surveying services, attending hfformafional meetings, and perfbnning hydrologic analyses. We believe that ~ mitigation will be welcomed by a majority, ffnot all oft_he riparian landowners affected by any water level changes. The Department will be sensitive to any change in flood damage p~tential caused by the restored water levels. At this time we have not determined the appropriate elevations or exact location(s) for the ditch block(s).
