Environmental Memo <br />To: Katie Larsen, City Planner <br />From: Tom Hoffman, Environmental Coordinator <br />Date: September 24, 2025 <br />Re:Environmental Comments– 7920 Lake Drive- Lino Lakes Dealership <br />Staff has reviewed the submittals and had recommended the following: <br />1.CBMH 3 should be a sump structure to provide pretreatment before discharging <br />into the infiltration basin. Otherwise, an additional structure should be proposed <br />prior to the outlet as a sump. <br />2.Recommend planting native species or low mow fescue adjacent to the parking <br />lot where the site drains to the stormwater bmp. <br />a. Filtration of additional buffer will be beneficial to soil stabilization, <br />pollutant filtration, and wildlife/pollinator habitat. <br />3.Rock mulch bed for landscaping to be flush with ground level. <br />4.Remove tree plantings from within the infiltration basin 1 as this will lead to <br />maintenance issues. <br />a. Removal of the trees from the basin will likely change the vehicular <br />hardscape coverage calculations <br />5.Infiltration Basin 1 is being proposed as a snow storage area, staff highly <br />recommends storing snow outside of the basin. Storage within the basin will lead <br />to higher sedimentation rates, increased chloride, and maintenance issues. <br />6.Retaining wall around infiltration basin 1 is concerning for future maintenance <br />operations. <br />7. Infiltration Basin 1 shows being stabilized with sod, provide live plugs and native <br />seed like Basin 2. <br />8. End cap parking breaks should have landscaping provided <br />9.8’ privacy fence should be constructed of maintenance free material <br />10. Glare shield to be provided on parking lot lighting <br />11. NPDES permit will be required for the project. Provide proof of permit before <br />construction. <br />a. Provide inlet protection in both CB adjacent to Kelly Street <br /> <br />
