STONEWOOD, LLC CONSERVATION DESIGN ANALYSIS
<br /> and local site conditions dictate. Additionally, the buffer will require permanent monuments
<br /> signifying the existence and location of the buffer.
<br /> D. Topographic Survey (Drainage)
<br /> The Grading and Site Plan indicates that the Project Site generally ranges from a topographic
<br /> high of 1010 feet to a low of 960 feet (wetland basin 3 water level). The existing drainage is
<br /> generally overland flow toward one of two wetlands and ditched wetland that drains to an
<br /> unnamed tributary to Lake Minnetonka.The grading and site plan proposes modest grading (red
<br /> circles in Figure 5) and installation of two stormwater infiltration basins (red arrow in Figure 5).
<br /> Infiltration basins as well as the previously noted base wetland buffer width will mitigate water
<br /> quality received by the unnamed tributary to Lake Minnetonka.
