Memorandum ,�Bonestroo <br /> 2335 Highway 36 W <br /> St.Paul,MN 55113 <br /> To: Christine Mattson, Project: 460 East Long Date: 7-22-11 Te1651-6364600 <br /> Melanie Curtis Lake Road Fax 651-636-1311 <br /> From: John Smyth Client: Orono www•bonestroo.wm <br /> Re: Wetland Buffer Compliance Check File No.: 139-08000 <br /> The above reference address was reviewed on 7-22-11 to determine if the wetland buffer had <br /> been established per the approved plan completed by Loucks Associates dated 6/19/08. Spoil <br /> piles and construction debris have been removed from the buffer, however the area of the buffer <br /> lacks topsoil and as a result has limited vegetative establishment. There is also currently a play <br /> house structure within the buffer that will need to be placed outside the buffer. Due to the lack of <br /> native vegetation in large portions of the buffer it currently is not acceptable. Areas with limited <br /> native vegetation will require additional seeding. It is recommended that 2-3 inches of top soil or <br /> compost is tilled in to provide nutrients to the soil prior to re-seeding. <br /> In addition the buckthorn in the wooded area has not been removed per the approved plan. The <br /> approved plan provided by Loucks Associates should be followed or the procedures listed below <br /> should be followed for the buckthorn removal. <br /> Buckthorn removal procedures.• European buckthorn greater than 0.5 inch diameter will need to <br /> be cut within six inches of the ground and the stump treated with an appropriate herbicide(e.g. <br /> 25% solution of glyposate, pic%ram, or equivalent) within 10 minutes after cutting. Cut stems <br /> can be allowed to fall where cut, and then decompose on the ground over time. These efforts <br /> shall occur when temperatures area above 25f to ensure herbicide uptake into roofs All other <br /> buckthorn smaller then 0.5 inch diameter should be treated with appropriate he�bicide and with a <br /> seasona/ly appropriate method. <br /> Once the buckthorn and other areas are ready for seed they should be seeded with the approved <br /> seed mix attached. <br /> A few companies that provide buckthorn removal and native seeding include the following: <br /> Prairie Restoration Inc.: (952) 955-3400 <br /> Minnesota Native Landscape: (320) 968-4222 <br /> K:\139\13908000\Word\Work_In_Progress\Wedand Ordinance Compliance\460 East Long Lake Road\CM&MC_JS^460 East Long Lake Road 7-22-11 wmpliance check.doa [TNS 06-2010]Page 1 of 3 <br />
