Wetland Delineation <br /> A wetland delineation was conducted by Jacobson Environmental on October 12, 2017. <br /> Three wetlands were delineated within the parcel, all located within the projected Lot 2 <br /> boundaries. Basin 1 was identified as a Type 1 PEM1Ad ditched seasonally flooded basin. <br /> Basin 2 was identified as a Type 5 PUBH shallow open water basin. Basin 3 was identified as <br /> a Type 2 PEM1 Bd ditched fresh wet meadow. The scope of this project will not impact any <br /> wetlands. The wetland delineation report was submitted to the Minnehaha Creek Watershed <br /> District in October and LGU approval is anticipated soon. <br /> D. Topography <br /> The topography of the site can be seen on the Figure 4—Topographic Map, depicting MN <br /> Lidar topographic data. Maxwell Bay is located on the southwest border of the site and has <br /> the lowest elevation across the site. Basin 2 is also a low spot within the project area, <br /> surveyed at approximately 938 feet. The northwestern corner of proposed Lot 1 is low and <br /> appears to slope downward offsite into a small wetland. <br /> E. Conceptual Greenways&Open Space Corridors <br /> The City of Orono—Conceptual Greenway Corridor Alignment Map shows that the project <br /> roughly within a conceptual greenway corridor. The portions of what was considered "maple- <br /> basswood forest" appear to be included within the corridor. To ensure minimal impacts are <br /> made to this site and ecological corridors are maintained, a 10-foot wide no-build setback is <br /> proposed along each side of the proposed lot lines, which will keep a 20-foot wide buffer <br /> between lots, at minimum.This is expected to maintain the ecological corridor within the site. <br /> Conservation Design <br /> A. Topography <br /> The topography of the site is highest on the southern portion of the property. The landscape <br /> slopes down to the north towards Basins 1, 2, and 3. The southwestern edge of the site is along <br /> Maxwell Bay, and the topography quickly grades down to the lake edge. The northwestern edge <br /> of proposed Lot 1 slopes down to the northeast offsite, into what appears to be a wetland off of <br /> Maxwell Bay. <br /> 3 <br />
