AN ORDINANCE AMENDMENT REGARDING
TREE PROTECTION
The City Council Of Edina Ordains:
Section 1.Chapter 10, Article III of the Edina City Code is amended to add Division
3 as follows:
DIVISION III. TREE PROTECTION
Sec. 10-82.Preservation, protection and replacement of Protected Trees: This Division
applies to: grading permits, demolition permits; subdivisions applications;
building permit applications for principal and accessory structures including a
garage, deck or a pool; and additions to principal and accessory structures. This
Division does not apply to City parkland, which follows tree protection
guidelines outlined in Edina’s Comprehensive Plan and City Park Master
Plan.
(1)Purpose: Edina is fortunate to have a robust inventory of mature trees that
form an integral part of the unique character and history of the city, and that
contribute to the long-term aesthetic, environmental, and economic well-
being of the city. The goal of this Section is to preserve Edina’s high valued
trees, while allowing reasonable development to take place and not interfere
with how existing property owners use their property. The purpose of the
ordinance is to:
a.Preserve and grow Edina’s tree canopy cover by protecting mature
trees throughout the city.
b.Protect and enhance property values by conserving and adding
to the distinctive and unique aesthetic character of Edina’s tree
population.
c.Protect and enhance the distinctive character of Edina’s neighborhoods
d.Improve the quality of life for all stakeholders, including city residents,
visitors and wildlife.
e.Protect the environment by the filtering of air and soil pollutants,
increasing oxygen levels and reducing CO2; preventing and reducing
erosion and stormwater by stabilizing soils; reducing heat convection;
decreasing wind speeds; reducing noise pollution and decreasing the
urban heat island effect.

f.Protect and maintain healthy trees in the development and building
permit processes as set forth herein; and prevent tree loss by
eliminating or reducing compacted fill and excavation near tree roots.
(2)Definitions:
a.Protected Tree: Any tree that is structurally sound and healthy, and
that meets one of the following:
i.a deciduous tree that is at least 8 5 inches dbh, except box elders,
poplar, willow, silver maple, black locust, fruit tree species, ash, and
mulberry.
ii.a coniferous tree that is at least 20 15 feet in height.
b.Removable Tree. Any tree not defined as a Protected Tree, and as
defined as an invasive species by the Minnesota Department of Natural
Resources.
c.Critical Root Zone. The minimum area around a tree that is left
undisturbed. The critical root radius is calculated by measuring the
tree’s diameter at breast height. For each inch of tree diameter, 1.5 feet
of root zone radius must be protected. For example, if a tree’s dbh is 10
inches, then its critical root zone radius is 15 feet (10 x 1.5 = 15). If the
critical root zone of a tree on site or an adjacent property must be
disturbed for construction or construction activity, a plan for the
disturbance shall be submitted as part of the Tree Protection Plan
subject to review and approval of the city forester to minimize the
damage.
d.Diameter at Breast Height (dbh). The dbh shall be measured at a height
of 4.6 feet.
e.Transplanted Tree. A protected tree which is removed from a
lot and replanted to another private lot or a public space in
Edina.
f.Heritage Tree. A protected deciduous tree above 30” dbh and a
protected coniferous tree taller than 30 feet.
(3)Applications for all permit types identified in Sec 10-82 must include a
tree protection plan indicating where Protected and Heritage Trees are
located and, their species, caliper, and health. The plan must show how
Protected and Heritage Trees are preserved and protected during

are proposed to be removed and the location, species and size of all
replacement tree(s). The Tree Protection Plan should be coordinated
with the Stormwater Management Plan; proposed and protected trees
should be shown on the stormwater management plan to ensure no
conflicts.
(4)If a Protected Tree is removed, except as allowed for in paragraph (5), it
must be replaced with one (1) tree trees equal to at least 75% of the
deciduous dbh and 75%of the coniferous height in feet,as applicable
, subject to the following conditions:
a.Protected trees must be replaced with species of a similar
type (deciduous or coniferous) according to Part 11 that are
normally found growing in similar conditions and that are included
in Hennepin County’s “Recommended Tree List” . on the list of
acceptable replacement species on file with the city forester.
b. Replacement trees must be varied by species.
b.Replacement trees must not be subject to known epidemic diseases or
infestations. Disease or infestation resistant species and cultivars are
allowed.
c.Replacement trees must be at least three and one-half inches
(23.5”) in caliper for deciduous trees and a minimum of eight feet
(78’) tall for coniferous trees.
d.Replacement tree plans are subject to approval by the City Forester
before implementation.
e.The tree protection plan shall be verified at the time of final inspection
for the building permit.
f. If the city determines that there is no appropriate location for some or all
the required replacement trees, those trees will not be required on site.
f.Failure to replace protected trees on site results in a payment fee
of $300 per dbh below 75% of the dbh removed, or $300 per
coniferous foot below 75% of the foot removed.
(5)Protected Trees may be removed without mitigation, in the following areas:

infrastructure improvements including public roadways, stormwater retention

(5)If a Heritage Tree is removed, it must be replaced with protected
trees at least 100% of the dbh or coniferous feet, subject to the
following conditions:
a.Heritage trees must be replaced with species of a similar type
(deciduous or coniferous) that are normally found growing in
similar conditions and that are included in Hennepin County’s
recommended tree list (xlsx).

(6)Before construction, grading or land clearing begins; city-approved tree
protection fencing, or other method must be installed and maintained at

fencing must remain in place until all demolition and construction is
complete.
(7)No construction, compaction, construction access, stock piling of earth,
storage of equipment or building materials, or grading may occur within the
critical root zone areas of trees to be protected, unless there are no other
on-site alternatives. If there are no other alternatives, a plan for this activity
would need to be reviewed and approved by the city forester and included
in the tree protection plan. A reasonable effort must be made when
trenching utility lines to avoid the critical root zone.
(8)When construction is complete all trees to remain must have the soil out to
their drip line aerated and de-compacted. Aerating must include multiple
concentric circles of 1” holes, 2” deep, or as recommended by an arborist.
(9)If Protected Trees and/or Heritage Trees were removed within one (1)
year prior to the date the development, subdivision application,
demolition, grading and building permit applications were submitted,
these Protected Trees and/or Heritage Trees are also subject to the
replacement policy set forth in paragraphs
(4) and (5) above.
(10)Any tree transplanted on-site shall not be counted as a protected tree or
heritage tree under this section and therefore does not require requires
replacement under this section, provided it is viable at 36 months after
the permit’s final inspection per Part 12.
(11)Amount of required replacement trees in (4) and (5) above shall be
a variety of types and sizes as demonstrated below. Species shall comply
with Hennepin County’s “Recommended Tree List.”

(12) Financial Guarantee.
a.The City shall, at its option, require cash escrow or a letter of credit
satisfactory to the City in the amount of 110 percent of the value

released based on the following schedule:
i.Upon issuance of a Certificate of Occupancy and approval
