2 • Comprehensive Stormwater Management Plan, prepared by Loucks, dated 2/21/22 • Geotechnical Evaluation Report, prepared by Braun Intertec, Inc., dated 1/11/19 • Operations and Maintenance Plan, prepared by Loucks, dated 4/11/22 ANALYSIS General Site Characteristics Otter Lake Animal Care Center is located at 6848 Otter Lake Road. The proposed project will involve a 2,850 square foot addition to the existing 4,000 square foot building and expansion of the existing parking lot. These additions will require 0.8 acres of disturbance to the 1.51 acre site. The impervious surface will increase from 0.304 acres to 0.614 acres due to the building addition and expanded parking lot. New utilities and landscaping will also be added. An existing stormwater pond on the north perimeter of the site will be deepened and regraded as part of this project. Land Cover Pre-settlement land cover (Marschner) was Aspen-Oak Land, with small groves of trees mixed with prairie. Historically fire frequency determined the abundance and distribution of species. Minnesota Land Cover Classification System (MLCCS) data indicates the following land cover types: Buildings and pavement with 76-90% impervious cover, medium-tall grass altered/non-native dominated grassland, and short grasses on upland soils. Most of the trees on the parcel are cottonwood, willow, cedar, and boxelder. A row of spruce trees on the property to the south provides screening between the properties. Rare, Unique, or Significant Resources While Blanding’s turtles (Emydoidea blandingii) have been documented within a one- mile radius of the proposed project site, it seems quite unlikely that they will be present on the site itself due to the prevalence of barriers that surround the property (Otter Lake Road, agricultural land, wetlands isolated from larger wetland complexes, etc.). The site plan does include surmountable curb, which would benefit wildlife that may be using the area around the stormwater pond. Ensuring that the erosion blanked used is natural netting will provide additional wildlife protection. No additional measures for rare, unique, or significant resources should be required.
