� T <br /> e. The subject parcel was identified as a conceptual greenway corridor on 1�Iap 3A-5 and <br /> has a high quality community onsite in the form of the ma.ple-basswoad forest present. <br /> Due to this high qualiry community, management and protection will occur in the forms <br /> of removal of invasive species present as well as the attempt to avoid any and all <br /> significant trees to the extent possible. When removal of significant trees is deemed <br /> necessary, these trees will be replaced in accordance with City of Orono requirements. <br /> No rare plant communities were observed on site and were not identified on Map 3A-5. <br /> Many azeas onsite are dominated by invasive species, including garlic rnustard, reed <br /> canary grass, and buckthorn. While management efforts will take place, due to the low <br /> quality nature of these areas, no speciaJ protection of these areas are necessary. <br /> 4. Conservatian Design Master Plan <br /> a. The topography of the site is rolling hills, with the highest point located in the central <br /> portion of the property, where the existing residence is situated. Stormwater runoff on the <br /> southern half of the property drains southwazds in the direction of and into Wetland 5, <br /> which is adjacent to Shoreline Drive on site. 4n the northem portion of the parcel, the <br /> majority of the stormwater runs to the eastern edge of the property and into Wetland 2 <br /> and Taaager Lake, although stormwater also flows into Wetland 3 aiong the north edge <br /> of the property,as well as off site to the west. Wetland 2 is a closed, depressional wetland <br /> located in the north central portion of the property and coilects stormwater runoff from a <br /> smail percentage of the property as well. Wetland 4 is also a closed depressional wetland <br /> and most of its water source is the driveway and turnaround area for the garage of the <br /> residence to the south of the Heritage Lane cuJ de sac. Historic photographs were <br /> reviewed and showed no signif cant changes from the current property azrangement. <br /> b. The existing drainage patterns have primarily been maintained. Stormwater on the <br /> southern half of the property will continue to drain southwards into Wetland 5. The <br /> majority of stormwater on the northern portion of the parcel rtins to the eastern edge of <br /> the property into Tanager Lake and north into wetland 3. Contours within Lots 1,2, and 3 <br /> will likely be manipulated to each accommodate a future proposed residence, but will not <br /> significantly re-direct surface water or affect the wetlands or their functions. <br /> c. Invasive species were evaluated on April 27, 2015, and include common buckthorn, <br /> zeed canary grass, gazlic mustard, and narrowleaf cattail. Grouped locations can be found <br /> on the attached map. Buckthorn seedlings, saplings and trees run along the north <br /> boundary and east border with Tanager Lake. Reed canary grass is present in isolated <br /> populations within Wetlands 3, 4, 5 and 6. Garlic mustard is located in the adjacent <br /> upland area around Wetla.nd 5 as well as in isotated patches throughout the maple <br /> basswood forest. Attached is a vegetation management plan for the invasive species <br /> observed onsite. <br /> d. The trees existing on the sub}ect parcel range from poor to good health. Although some <br /> have died or are dying, thc majority appeaz ta be in good health with no signs of disease. <br /> Dead trees will be removed from the lots if they aze within grading areas. <br /> Although only preliminary lot development plans are in place,Lots 1-3 will be developed <br /> for single residence houses. Tree ciearing will be avoided to the extent possible, but due <br /> Svoboda Ecological Resources 3 185-225 Old Crystal Bay Road <br /> Pzoject No.:2015-613 I-Iomestead Pactners <br />
