M �eonestroo <br /> emo �R°� <br /> Anderlik 6 <br /> ��4ssociates <br /> Englneen 6 Archltects <br /> Project Name: 300 Stubbs Bay Rd N Client: City of Orono <br /> To: Evelyn Turner, City Planner File No: 139-06-000 <br /> From: John Smyth, C.W.D., (651) 604-4708 Date: July 24, 2006 <br /> Re: Buffer Ordinance Compliance <br /> Remarks: <br /> Per Division 1. Sec. 78-1601 of the Wetland Protection Ordinance, the proposed construction on this lot <br /> trigger's the ordinance due to the following proposed work: <br /> o Disturbed property drains towards the wetland. <br /> o Grading exceeds 50 cubic yards. <br /> o Net increase in the square footage of impervious surface area. <br /> • Driveway as shown on 7/10/06 plan disturbs the wetland buffer area, however if access is created <br /> from existing driveway on outlot A per plat conditions this impact may not occur. <br /> • The wetland on this property has been classified as a preserve. This classification of preserve <br /> requires a 50' buffer that should be protected during construction. <br /> • The upland buffer has some invasive species such as prickly ash, however it also has a good <br /> herbaceous layer and other natives that will provide filtering of nutrients and habitat thus <br /> recommend preserving the vegetation in the buffer rather the requiring disturbance for seeding. <br /> • A silt fence is being installed to protect the wetland and buffer area during construction. The <br /> property owner has approximately 50 feet of space that can be disturbed for turf prior to the buffer. <br /> It is recommended that signage or other markers are placed on the upslope edge of the buffer so <br /> the property owner is aware where the buffer starts. If encroachment occurs into the buffer the <br /> disturbed areas should be revegetated according to the city's ordinance. <br /> Bonestroo,Rosene,Anderlik and Associates,Inc, www.bonestroo.com <br /> ❑St.Paul O�ce: ❑Milwaukee Office: ❑Rochester Office: ❑Willmar Office: ❑St.Cloud Office: ❑Grayslake Office: <br /> 2335 West Highway 36 1516 West Mequon Road 112 7ih Street NE 205 Sth Street SW 3721 23rtl Street S 888 East Belvidere Road <br /> St.Paul,MN 55113 Mequon,WI 53092 Rochester,MN 55906 Willmar,MN 56201 St.Cloud,MN 56301 Grayslake,IL 60030 <br /> Phone:651-636-4600 Phone:262-241-4466 Phone:507-282-2100 Phone:320-214-9557 Phone:320-251-4553 Phone:847-548-6774 <br /> Fax:651-636-1311 Fax:262-241-4901 Fax:507-282-3100 Fax:320-214-9456 Fax:320-251-6252 Fax:847-548-6979 <br />
