Final Plat Resubmittal Landscape Plans, dated July 26, 2019, received June 26, 2019.
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.

B. 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.

* Residential development - mitigation replacement trees are in addition to landscape required tree counts.
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

Deciduous Shade Trees 142 50% >25% required
Coniferous Trees 107 38% >25% required
Ornamental Trees 35 12% <15% required
Tree Count 284
A. 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.

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.

Lucius Jonett, PLA (MN)
