Wildhurst Woods, Orono <br />NATURAL RESOURCES INVENTORY <br />Conservation Design Analysis <br />MLCCS Land Cover Classification <br />The City of Orono 2040 Community Management Plan Comprehensive Plan - Minnesota Land <br />Cover Classification map (Attachment B) shows the site mapped with: (1) forests, (2) tall <br />grasses, and (3) shrubland. More specifically, the site is mapped with maple -basswood forest, <br />grassland with sparse deciduous trees - altered/non-native dominated vegetation, and <br />altered/non-native dominated upland shrubland (Figure 4). Field observations were generally <br />consistent with the identified MLCCS cover types. <br />Tree Survey <br />A tree survey was completed as part of the planning process for the Wildhurst Woods project. <br />Identified significant tree species (DBH >6") included sugar maple, green ash, red oak, <br />ironwood, basswood, black cherry, red pine, red elm, and bittemut hickory (Attachment Q. The <br />tree survey report noted that many green ash individuals throughout the project area show signs <br />of infection with Emerald Ash Borer. Common buckthorn shrubs (<6" DBH) were also noted to <br />be present in portions of the understory. <br />Wetland Inventory and Delineation <br />A wetland delineation completed for the site in August 2022 by Kjolhaug Environmental <br />Services was subsequently approved by the WCA LGU (Minnehaha Creek Watershed District) <br />in November 2022 (Attachment D) as shown on Figure 2 and summarized in Table 1 below. <br />Table 1. Wetlands delineated on Wildhurst Woods site. <br />Topographic Survey <br />Preliminary plat documents (Attachment A) and Figure 2 include 2 -foot lidar topographic <br />contours. Topography on the site is highest in the southwest corner at 1024 feet MSL, and from <br />there slopes downhill to the northeast. A diagonal topographic saddle in the center of the site at <br />950 feet MSL allows runoff to drain to the northwest (to Wetland 2 located below 938 feet MSL) <br />and to the southeast (over Widlhurst Trail and to Forest Lake). Northeast of the saddle, <br />topography rises again to a high of 964 feet MSL. The site does not include any bluffs as defined <br />in the City of Orono Shoreland Management Ordinance. <br />Conceptual Greenways and Open Space Corridors <br />The Conceptual Greenway Corridor Alignment map (Attachment E) shows the site within a <br />"conceptual greenway corridor" which includes "medium quality natural communities" which <br />partly correspond to the MLCCS mapped maple -basswood forest. <br />0► <br />Wetland Type <br />Circular <br />Cowardin <br />Eggers and Reed <br />Wetland ID <br />Dominant Vegetation <br />39 <br />2 (0.09 -ac <br />Type 1 <br />PEM1A <br />Seasonally flooded basin <br />Reed canary grass, common <br />onsite) <br />buckthorn <br />3 (0.03 -ac <br />onsite) <br />Type 1 <br />PEM1A <br />Seasonally flooded basin <br />Reed canary grass <br />Topographic Survey <br />Preliminary plat documents (Attachment A) and Figure 2 include 2 -foot lidar topographic <br />contours.
