Drainage Patterns <br /> The existing drainage patterns have been primarily maintained. The topography of the site is not <br /> anticipated to be drastically altered, therefore, site drainage will typically continue to flow to the <br /> three delineated wetlands on the site. <br /> C. Invasive Species <br /> Invasive species were evaluated in October of 2017, and included reed canary grass. Outlined <br /> locations of this species can be found on the Figure 10—Invasive Species Map. Reed canary <br /> grass was found within Basins 1 and 3.All invasive species were found within Lot 2,which will <br /> not be altered for the project. Because invasive species were typically only found on the unaltered <br /> lot, no invasive vegetative management plan is suggested at this time. <br /> D. Existing Trees <br /> The majority of the trees existing on the subject property appear to be in fair to good health with <br /> no major diseases observed. Trees that must be removed for house and driveway construction <br /> will be removed and disposed of according to the Orono city code. The trees that are impacted <br /> will be replaced at a 2:1 ratio and will abide by all Orono city codes regarding tree replacement. A <br /> 20-foot wide buffer will exist between all lots(10 feet on either side of the lot line)to minimize tree <br /> removal. <br /> E. Significant Tree Stand Criteria <br /> A few of the forested areas of the project area meet the criteria for significant tree stands by <br /> occupying 500 or more square feet with contiguous crown cover and DBH over 6 inches. The <br /> trees identified on the central and southern portion of proposed Lot 1 were typically part of a <br /> significant tree stand. The proposed home construction is located within a small portion of this <br /> tree stand. The precise placement of the home will be determined as to minimize the need for <br /> tree removal and uphold the favorable views between existing homes surrounding the site. No <br /> significant tree stands were identified within Outlot A. <br /> F. Wetland Impacts <br /> The delineated wetlands within the parcel boundaries will not be impacted during construction or <br /> development activities, and buffer rules and setbacks will be followed. Buffers and setbacks will <br /> assist in maintaining the quality and functionality of the wetlands by providing additional surface <br /> water treatment to runoff. <br /> G. Ecological Communities <br /> Portions of the ecological communities of the site are of medium quality(typically what was <br /> identified as the maple-hardwood forest areas). The majority of the northern and central portions <br /> of the site have been classified as altered with no native species present. The driveway access <br /> proposed for Outlot A does not appear to alter or further degrade the ecological communities <br /> onsite.A gravel driveway currently exists at the location of the proposed shared driveway, which <br /> is expected to minimize or potentially remove any impacts to Outlot A. The construction of the <br /> home on Lot 1 will produce some impact to the area of medium quality forest within the lot, but <br /> tree removal will be minimized whenever possible. <br /> H. Positive and Negative Views <br /> The project proposes a 10-foot no-cut zone on each side of the proposed lot lines,which will <br /> 4 <br />
