5.Environmental Memo dated May 28,2025 <br /> C I T Y� O F Environmental Memo <br /> IN [jN"E <br /> To: Katie Larsen,City Planner <br /> From: Tom Hoffman, Environmental Coordinator <br /> Date: May 28, 2025 <br /> Re: Environmental Comments—Erickson Properties Preliminary Plat <br /> Environmental Board had recommended the following at their May 28, 2025 meeting: <br /> 1. Stormwater management to be reviewed by City Engineer <br /> a. Use of Stormwater for irrigation purposes for the site should be evaluated <br /> and if feasible required as part of site development. Larger stormwater <br /> ponds constructed for fill should be evaluated for water reuse. <br /> b. Infiltration is required to be shown where feasible based on soil borings. <br /> If infiltration is not feasible follow the Minimum impact design standards <br /> (MIDS)) as designed by the MPCA <br /> 2. EOF should be shown as stabilized rock to prevent erosion of the stormwater pond. <br /> 3. Low maintenance turf should be evaluated throughout development. Ground covers <br /> should be drought resistant to reduce the need for irrigation use. <br /> 4. Provide a tree inventory for the site showing only significant deciduous trees of 6" in <br /> dbh or larger. Coniferous trees are measured by height,coniferous trees over 12'would <br /> be considered significant. <br /> a. Coniferous trees should be measured by height not DBH. <br /> b. Remove off-site trees from the final tree inventory <br /> c. Mitigation table provided for trees outside of basic use. <br /> 5. On section 4.1, bold or change the color of the tree tags to be visible. <br /> 6. Current plans show Twelve (12)trees being removed for storm water ponding. <br /> Stormwater ponding is not included under the basic use area and therefore mitigation <br /> will be required of those removals. <br /> Page 231 of 240 <br />
