1 1 III. PROJECT BACKGROUND ' At the time of the 2006 site visit the wetland ed e was lo g cated usmg a Le�ka GPS urut and , was 29,104 sf in size. By subtracting the original wetland size from that number the wetland was determined to be 8,279 sf larger after the expansion. Originally the wetland and buffer areas were seeded by L&K Contractors usmg a native seed mix provided by Specialty Seed. ' The seed mix was consistent with the mix specified in the original plan.At the time of the 2006 site visit it did not appear that the new wetland and buffer vegetation had been mauitauled after seeding. Recommendanons in the 2006 report were to hire an experienced ' restoration company to manage invasive and weedy species in the buffer and establish the native plant community. ' Since 2006,the applicant hired Prairie Restorations,Inc. (PRn to manage the vegetation of the replacement wetland and buffer. PRI completed the following treatments since 2006. ' Oct 2046: sprayed for cool season grasses Apri12007: performed controlled burn. May 2007: spot sprayed for black nightshade, Canada goldenrod, Canada thistle , June 2007: spot sprayed for Canada goldenrod, Canada thistle, creeping Chazlie June 2007: spot mowed cool season grasses, reed canary Ju1y 2007: continued monitoring for future work, integrated plant maintenance ' In September 2006 Minnehaha Creek Watershed District asked that an as-built survey be completed on the wetland to verify the berm was constructed as proposed. According to � the applicant an as-built survey was completed and submitted to MCWD as requested. � IV. METHODS ' Vegetation and hydrology were documented at fixed photo reference points as shown on Figure 3. Plant species dominance was estimated based on a meander survey throughout the new wetland area. The location, composition, and extent of plant communities were , described for the replacement area.. Hydrology characterizations consisted of aerial coverage estimates during the site visit. Photographs were taken at one to three fixed photo pomts at each replacement wetland and were referenced to fixed points identified on the , wetland replacement plan and labeled accordingly. All field observations took place during the growing season. I V. RESULTS ' Replacement Area 1 (Figures 3 and 4) was to consist of three sma11 areas excavated adjacent to the existing wetland on the north and south sides. A low wetland berm was to be constructed within the existing wetland to create an azea that would support woody ' �
