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.

A landscape plan has been submitted that does include all requirements. B. The landscape plan does not meet the landscape layout requirements; 1. No utility conflicts; prefer that the trunk of trees shall be 10 feet from the nearest utility, 5 feet minimum required, including yard drains and storm sewer lines. Ken Roberts Planning Director City of Lake Elmo July 30, 2019 4 T:\6443 Lake Elmo\22 Springs of Lake Elmo\01 Preliminary Plans\2019-07-26\2019-07-30 Springs of Lake Elmo Landscape Plan Review.docx C. Interior Parking Lot Landscaping – The development does include several interior parking lots and none of the proposed parking lots exceed 30 stalls requiring additional landscaping. D. Perimeter Parking Lot Landscaping – The development does include perimeter parking lots and meets all landscape requirements by providing vegetated screening between four and six feet in height and 90% opaque year round and includes one deciduous or coniferous tree for every 40 linear feet along the property line. E. Screening – The landscape plan does meet screening requirements by providing a vegetated screen of at least six feet in height and not less than 90% opaque year round and includes one deciduous or coniferous tree for every 40 linear feet along the property line. Findings: 1. Resubmitted plans address all comments from the previous review. 2. See attached markup on the landscape plan showing trees in conflict with yard drains and utility lines. There are several constrained open spaces, where after the utilities are installed, field adjustments of trees to fit the remaining open space will be difficult to meet City spacing requirements. The landscape plan needs to be updated with adjusted tree locations to maintain 10’ clearance where possible, otherwise maintaining at least 5’ as agreed upon. Recommendation: It is recommended that a condition of final approval includes submitting a revised landscape plan. Sincerely, Lucius Jonett, PLA (MN) Wenck Associates, Inc.
