MONO COPY KJoIJiuG ENVIRONMENTAL SERVICES COMPANY volkorr Prouiding Sound,Balanced,Compreltensiue Natural Resource Solutions Memorandum To: Christine Mattson, City of Orono From: Mark Kjolhaug—Kjolhaug Environmental Services Company Date: August 22, 2012 Re: 1050 Willow View Drive/Building Permit#2012-00596 Buffer Establishment and Management Per Mark Perry's August 16, 2012 letter to you, the wetland we delineated on the described Nicklow parcel is a Management Level 3 wetland that requires a 16.5' upland buffer. The purpose of this memo is to describe the buffer establishment and management plan for the property. It is our understanding that the delineated wetland boundary and 16.5' wetland buffer are indicated on the plan that has been provided to the City by Jerry Haugen of JRS Pools. While most of the buffer is currently dominated by native willow shrubs and Canada goldenrod, portions on the west have an abundance of Canada thistle. In a few locations, the buffer is dominated by mowed Kentucky bluegrass and other lawn species. Areas with these weedy and invasive species will be killed using Roundup or an equivalent chemical during the month of September. In spring of 2013,the same area will be retreated with Roundup in May to kill all remaining weeds and lawn grass. Dead sod will be removed if necessary to establish a suitable seed bed. In spring 2013 (after Roundup treatment),the area will be hand broadcast seeded with MnDOT Seed mix 350 or an approved equivalent at a rate of 121bs PLS/acre for grasses and 5 lbs PLS/acre for forbs with no fewer than 5 species of each type. A nurse crop seeded at a rate of 20 lbs/acre will also be utilized to discourage weed growth. Seeds will be raked and packed to provide good contact and ensure successful germination. No fertilizer will be utilized. Following seeding, the area will be covered with anchored clean straw at a rate of 1.5 tons/acre. Required erosion control will be utilized as necessary to protect the wetland and buffer during the pool construction activities. At the discretion of the Nicklows, additional native wildflowers may be hand planted within the buffer area. All additional species will be wildflowers native to the region and compatible with the planted seed mix. The Nicklows will contract with a qualified revegetation company to 26105 Wild Rose Lane, Shorewood, Minnesota 55331, Phone: 952-401-8757, Fax: 952-401-8798
