MIDWEST NATURAL RESOURCES Ms. Tracey Rust The Excelsior Group 1660 Highway 100 South, Suite 400 St. Louis Park, MN 55416 August 17, 2021 Ms. Rust, Midwest Natural Resources, Inc. (MNR) is pleased to provide the following botanical survey report for the Trott Brook project site in Ramsey, Minnesota. (Figure 1). Project Limits and Existing Background Data The project area, which is approximately 196.1 acres, is located in Township 32 North, Range 25 West in the SWNE, SENE, NENE, and NWSE quarter -quarter sections of Section 9 and the NWNW, SWNW, and NENW quarter -quarter sections of Section 10 (Figure 2). Background data evaluated includes digital soil data, the Minnesota Biological Survey sites of biodiversity significance data layer, the Minnesota Department of Natural Resources (DNR) Native Plant Community (NPC) data layer, and surficial geology. According to the Anoka County Soil Survey (Table 1 and Figure 3), the site includes 15 different soil map units ranging from very poorly drained to excessively drained. Of these soil types, Rifle mucky peat (Rf) is often associated with rare plant species occurrences, but there are no sites of biodiversity significance nor NPC polygons mapped within the project limits. However, the sites of biodiversity significance data layer does identify a site, Trott Brook Wetlands, just outside of the survey area on the west side of Variolite Street. This site is classified as one below the minimum biodiversity threshold for statewide significance. Although sites with this designation lack occurrences of rare species or natural features, they may include areas of conservation value. Table 1.
