Location: North of Hudson Boulevard North, West of Keats Avenue North in Lake Elmo, MN Land Use Category: Rural Development Transitional being rezoned to Urban High Density Planned Unit Development Surrounding Land Use Concerns: The property to the north (Bentley Village) is Urban Medium Density Residential and is less intensive land use than the proposed Urban High Density Residential. Screening is required on the north boundary. The property’s use to the west (Rural Development Transitional) is unknown at the moment and east (Commercial) is a zone that is more intensive land use than this proposed Urban High Density Residential. Screening is not required on the east or west boundaries. To the south is Interstate 94 where screening is suggested to help with noise abatement. Special landscape provisions in addition to the zoning code: None.

There are 37 specimen trees identified in the tree inventory. The following tree ID numbers are defined as specimen, 3501-3534, 3557, 3561, and 3563. All specimen trees are proposed for removal. C. Tree replacement is required because more than thirty (30) percent of the diameter inches of significant trees surveyed will be removed. D. Tree replacement calculations does follow the required procedure. E. This project is residential development; therefore, mitigation replacement trees shall be in addition to landscape required tree counts. Ken Roberts Planning Director City of Lake Elmo May 7, 2019 3 T:\6443 Lake Elmo\22 Springs of Lake Elmo\01 Preliminary Plans\2019-05-06\2019-05-06 Development Name Landscape Plan Review.docx Landscape Requirements: The preliminary landscape plans do not meet the code required number of trees. The preliminary plans show fewer than the code required tree quantities.

A minimum one (1) tree is proposed for every fifty (50) feet of street frontage. 2. A minimum of five (5) trees are proposed to be planted for every one (1) acre of land that is developed or disturbed by development activity. The landscape plans do meet the minimum compositions of required trees: • At least 25% of the required number of trees shall be deciduous shade trees • At least 25% of the required number of trees shall be coniferous trees • Up to 15% of the required number of trees may be ornamental tree Master Plan Qty % Composition Deciduous Shade Trees 125 74% >25% required Coniferous Trees 44 26% >25% required Ornamental Trees 15 9% <15% required Tree Count 169 A. A landscape plan has been submitted that does not include all requirements. 1. The landscape plan does not include required City standard notes and details. Ken Roberts Planning Director City of Lake Elmo May 7, 2019 4 T:\6443 Lake Elmo\22 Springs of Lake Elmo\01 Preliminary Plans\2019-05-06\2019-05-06 Development Name Landscape Plan Review.docx B. The landscape plan does not meet the landscape layout requirements. • No utility conflicts; Prefer that the trunk of trees shall be 10 feet from the nearest utility, including water and sewer service stubs to each lot. C. Interior Parking Lot Landscaping – The development does include several interior parking lots. Only one meets the threshold of 30 parking spaces and does not meet the following landscape requirements. 1. At least 5% of the interior area of parking lots with more than 30 parking spaces is devoted to landscape planting areas. The parking lot is measured at approximatively 8,650 square feet and a planting bed measuring approximately 0 square feet separates the parking lot from the circle drive/drop-off area. The planting area is approximately 0% of the interior of the parking lot area. 2. The planting area includes 1 shade tree and does not satisfy the minimum required 4 tree planted to meet the requirements for this interior parking lot. D. Perimeter Parking Lot Landscaping – The development does include perimeter parking lots and does not meet the following landscape requirements. 1. Alongside and rear property lines abutting residential properties or districts, screening shall be provided, consisting of either a masonry wall, fence or berm in combination with landscape material that forms a screen a minimum of four (4) feet in height, a maximum of six (6) feet in height, and not less than ninety percent (90%) opaque on a year-round basis. Landscape material shall include trees, planted at a minimum of one deciduous or coniferous tree per forty (40) linear feet along the property line. E. Screening – The landscape plan does not meet screening requirements. Screening is required by City code. Screening shall be used to provide visual and noise separation of intensive uses from less intensive uses. Where screening is required in the City Code between uses or districts, it shall consist of either a masonry wall (chain link will not suffice) or fence in combination with landscape material that forms a screen at least six (6) feet in height, and not less than ninety percent (90%) opaque on a year- round basis. Landscape material shall include trees, planted at a minimum of one deciduous or coniferous tree per forty (40) linear feet along the property line. Additional landscape material such as shade trees or trellises may be required to partially screen views from above. A single, straight row of evergreen trees is inadequate for screening. Vegetative screening should consist of more than one row of evergreen trees and include a row of other trees or native shrubs in front of the evergreens to soften the “development wall” effect. Ken Roberts Planning Director City of Lake Elmo May 7, 2019 5 T:\6443 Lake Elmo\22 Springs of Lake Elmo\01 Preliminary Plans\2019-05-06\2019-05-06 Development Name Landscape Plan Review.docx Findings: 1. Tree calculations for mitigation and landscape requirements are based on 3” DBH trees. This diameter exceeds the minimum size required and provides fewer trees at a larger diameter. 2. Tree replacement calculations do not follow the required procedure. We are not able to follow the math of how the common, conifer, and nuisance species were tabulated. Please provide tabulations. 3. Preliminary landscape sheets do not include required City standard notes and details. Update details using City standard notes and details. 4. There are some landscape conflicts with utility lines. Please refer to attached document for problem areas. Please correct tree spacing so the trunk of trees shall be 10 feet from the nearest utility, including water and sewer service stubs to each lot. 5. The preliminary landscape plans do not calculate interior parking lot and perimeter parking lot tree plantings. Please refer to attached document for identified issues. Please update landscape plan to provide the required plantings. 6. The north side of the property will need to satisfy both screening and perimeter parking lot requirements. Recommendation: It is recommended that a condition of approval include submitting a revised landscape plan addressing findings 2-6 listed above.
