<br />August 27, 2024 <br />Oak-Land Middle School <br /> <br /> <br />Memorandum 2 <br />toward the disturbed acre requirement). Also include any trees required by the revised tree <br />preservation plan. <br /> Interior parking lot landscaping is required for the proposed parking expansion: 1 tree <br />for every 10 parking lot spaces or fraction thereof. With more than 40 spaces, 5 trees <br />will be required. Please add an additional tree within a planting island or along the <br />border of the parking lot. <br />o Ground cover materials should be defined with their own separate hatches (seeded, sodded, <br />and mulched areas) showing the extent of disturbed area restoration. <br />o Provisions for irrigation are required. Please include an irrigation plan or notes detailing how <br />trees and planting materials will be watered through the warranty period. <br />o Include the City Standard Tree Planting Detail. <br />o Revise landscaping note #7 on sheet C600 to read “6’ diameter and 4” deep.” <br />o A Topsoil Preservation Plan is required per 105.12.480 (a) (9). I could not locate an area <br />showing where site topsoil would be stored on the plans. Please ensure this is called out <br />somewhere on the drawings (Sheet C300 would be a good place). <br /> <br />GENERAL NOTES: <br />• I have some concern about how well American Larch will do on the dry slope along the utility corridor <br />that extends up to 10th street. They generally want more soil moisture. I would recommend selecting <br />another species. <br />• Please select a Dutch Elm-resistant cultivar of Elm rather than specifying Ulmus Americana. <br /> <br />RECOMMENDATION: <br />The landscape and tree preservation plans must be revised and resubmitted to address the items in this <br />memo. <br /> <br /> <br />Sarah Evenson, PLA (MN) <br />City of Lake Elmo Municipal Landscape Architect <br />P: (262) 391-7653 E: sarah@hkgi.com
