Environmental Board August 25,2021 Page 2 report included a detailed description of the site's characteristics, including soils, significant resources, stormwater management and drinking water protection, wetlands, and a tree preservation plan among others. Staff recommended approval of the request with the following recommendations: 1. A survery for rare,unique, and significant resources should be performed. This survey should include a data request to the MN DNR for Natural Heritage Information System data for this site. The survey should also include information on presence and/or extent of any MN DNR listed threatened, endangered, or special concern species. If any of the aforementioned species are identified on the site, their locations should be mapped as this may impact future work on the lots (lake access locations, for example). 2. Buffers for wetlands and shore of Amelia Lake should be established in accordance with Vadnais Lake Area Watershed Management Organization(VLAWMO) recommendations. This may impact the placement of the house on lot 2. The driveway placement on lot 2 may require a variance to be obtained from the Planning and Zoning Board. 3. Tree protection fence appears to encroach on protected root zone areas on trees on all four lots. Trees that have more than 30 percent of their root zones impacted shall be counted as removed and must be mitigated for at applicable rates unless they are in basic use areas. 4. Green ash (Fraxinus pennsylvanica) and Siberian elm(Ulmus pumila) appear on the list of trees intended to be saved. These trees should be removed if they are in the vicinity of other planned removals. Mitigation trees for removals of these species will not be required. 5. Red maple and sugar maple be removed from the suggested trees to replant with list on the Tree Mitigation Plan. 6. Stormwater basins are not part of the Basic Use Areas. Trees that are planned to be removed in these areas must be mitigated for at applicable rates. Mr. Schwartz inquired if this site was part the greenway system of Lino Lakes, and what would happen after a survey of rare and unique species was conducted. Mr. Nelson confirmed that the portions of the east shore of Lake Amelia is located within the greenway system. Mr. Nelson also noted that if endangered and/or threatened species were identified, it may impact how work is performed on the site. If special concern species were found, that should be communicated to homeowners as it may impact where they should establish lake accesses. Mrs. Holmes wanted to note that the tree removal is an area of concern. Having a large number of trees with only I I being designated to be mitigated for is alarming. Mr. Nelson noted that there may be more mitigation trees required for removals planned in the area of the stormwater basins as they are not considered part of the Basic Use Areas. DRAFT MINUTES
