Tree Preservation:
An existing conditions and site demolition plan showing tree survey, removal and
preservation plan has been submitted, including a tree inventory showing individual trees
that are exempt, removed and saved. The allowable tree removal limit is not exceeded,
therefore no mitigation plan or replacement trees are required.

Landscape Requirements:
The landscape plans meet the code required number of trees. The proposed landscape plans
show more than the code required tree quantities.
*Residential development - mitigation replacement trees are in addition to landscape required tree counts.
** Commercial, mixed-use development - mitigation replacement trees can be included toward landscape
required tree counts.
1. 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 not meet the minimum compositions of required trees:
• Up to 15% of the required number of trees may be ornamental tree
Master Plan Qty %

Deciduous Shade Trees 27 45% >25%
required
Coniferous Trees 20 33% >25%
required
Ornamental Trees 13 22% <15%

Tree Count 60
The landscape plans do show the required mitigation tree types and quantities.

A. A landscape plan has been submitted that does not include all requirements.
1. All utilities and pavements are not shown on the landscape plan to review for tree
placement conflicts.
B. The landscape plan does not include the landscape layout requirements:
• No utility conflicts with proposed tree locations; Prefer that the trunk of trees
shall be 10 feet from the nearest utility, including water and sewer service
stubs to each lot. Current ordinance is 5 feet minimum from nearest utility.
C. Interior Parking Lot Landscaping – The development does include interior parking lots.
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 5,521 square feet and a planting bed measuring approximately
6,578 square feet separates the parking lot from the northern building. The
planting area is approximately 119% of the interior of the parking lot area.
2. The planting area includes 8 shade trees satisfying the minimum required tree
planting requirements for interior parking lots.
D. Perimeter Parking Lot Landscaping – The development does not include perimeter
parking lots.
E. Screening – Screening is required along the north property line per City code. The
landscape plan utilizes existing trees north of the property, preserves existing trees on
site as a buffer to the north property line and proposes additional tree plantings to
enhance the screening. The landscape plan meets screening requirements.
F. PUD Amenity Points Requested
1. Additional Open Space standards have not been met.
Approximately 44% of the site not occupied by buildings is landscape outdoor open
space (50% minimum required).
Approximately 44% of the landscape outdoor open space is contiguous (50%
minimum required).
2. Pedestrian Improvement standards have been met.
A site and building design has been provided that allows for accessible pedestrian
and/or bicycle access through and/or around the site.
Addition detail on any decorative materials, access control or lighting should be
provided.
3. Plaza standards have been met
The development has included a public square that is wholly enclosed by buildings, is
14,555 square feet (1,000 square foot minimum required).

4. Enhanced Landscaping standards have not been met
• An enhanced Landscaping Plan has been provided that exceeds the
requirements of the Lake Elmo Design Standards Manual.
• The Landscaping Plan does not detail a resource efficient irrigation system.
• The Landscaping Plan has not been signed by a licensed landscape architect.
5. Theming standards have not been met
• Theming elements consistent with the 2013 Lake Elmo Theming Project,
including but not limited to signage, fencing, landscaping, lighting and site
furnishings, have not been shown on the landscape plans or in the details.
Findings:
• Up to 15% of the required number of trees may be ornamental tree per city code.
Currently, the percentage of ornamental trees is too high. But the applicant has
elected to use Enhanced Landscaping amenity points as part of their PUD submittal
and has provided landscaping above and beyond City minimum requirements. Having
a higher percentage of ornamental trees should be allowed for this development.
• All utilities and pavements are not shown on the landscape plan to review for tree
placement conflicts. We marked 8 trees on the attached figure that have potential of
having a utility conflict.
• The standard for the Pedestrian Improvement amenity requires trails, landscaping,
decorative materials, access control and lighting to create safe, clear and
aesthetically pleasing pedestrian facilities. A plan or details on any decorative
materials, access control or lighting should be provided.
• The standard for the Enhanced Landscaping amenity requires that the landscaped
areas should have a resource efficient irrigation system. A plan or details on how the
irrigation system will be designed to be resource efficient should be provided.
• The standard for the Theming amenity requires elements consistent with the 2013
Lake Elmo Theming Project. Addition detail on proposed signage, fencing,
landscaping, lighting and site furnishings, should be provided.

(within 10’) to proposed utilities.
