Otion Agnes M Eirsg James P Engeihardt Re: Stickney Pond File No. 139-2086 Dear Jeanne, Wt have reviewed the proposal to create a pond within an existing Type 2 cattail wetland at 2915 Somerset Lane, located on Lot 2, Block 4, Old Crystal Bay Road 2nd Addition. This wetland is protected by the City of Orono by ordinance, regulated by the Minnehaha Creek Watershed District at the State level as part of the Wetland Conservation Act (WC,-\), and under the jurisdiction of the U.S. Army Corps of F.ngineers (COE) at the Federal level. I discu.s.sed the propo.sed pond with John Smythe, a wetland scientist at our office. He had the following general comments in regards to excavating ponds within wetlands. It depends on the conditions of the wetland in question. It the wetland consists mainly of one type of plant such as reed canary grass or cattails, we prefer to see an increase in diversity by adding different types of habitat such as open water. For certain types of priority wetlands such as sedge meadows, Type 1 or 2 scrub-shrub, or wxx>ded wetlands, we do not recommend excavation. We prefer that fK)nds are constructed near the wetland fringe to remiwe reed canary grass whenever possible. The COE has a general permit No. 18 for excavation of a wildlife pond which should be followed. .Mitigation of the excavated wetland area could be required b>' the City c*r COE. however excavation is not regulated by the WCA. If the pond is con.structed in accordance with permit #18 the COE would probably not require mitigation. Cattails do have a benefit by providing habitat during the w inter months when other plants are beneath the snow. However, there Is a benefit added by excavating in an area of reed canary grass The profHised pond does not conform to permit #18 only because the sideslopcs arc too steep (4-foot H to 1-foot V). We would reci^mmend approval of the proposed pond if the grading plan is revi.sed to follow the attached guidelines. E.xisting topsoil should be salvaged for respreading over the disturbed areas. These areas should be restored with seeding using a wetland seed mixture such as MaDOT mixture 250. Please contact me at this office if you have any questions regarding this matter.
