Subd. 8. Grants to municipalities.
(a) The commissioner may, in the name of the state and
within the limit of appropriations provided, make a grant to a municipality with an approved
pest control program for the partial funding of municipal sanitation and reforestation programs
to replace trees lost to pest, disease, or natural disaster. The commissioner may make a grant to
a home rule charter or statutory city, a special purpose park and recreation board organized
under a charter of a city of the first class, a nonprofit corporation serving a city of the first class,
or a county having an approved disease control program for the acquisition or implementation
of a wood use or disposal system.
(b) The commissioner shall adopt rules for the administration of grants under this
subdivision. The rules must contain:
(1) procedures for grant applications;
(2) conditions and procedures for the administration of grants;

reforestation must be combined into one grant program. Grants to a municipality for sanitation
must not exceed 50 percent of sanitation costs approved by the commissioner including any
amount of sanitation costs paid by special assessments, ad valorem taxes, federal grants, or other
funds. A municipality must not specially assess a property owner an amount greater than the
amount of the tree's sanitation cost minus the amount of the tree's sanitation cost reimbursed by
the commissioner. Grants to municipalities for reforestation must not exceed 50 percent of the
wholesale cost of the trees planted under the reforestation program; provided that a reforestation
grant to a county may include 90 percent of the cost of the first 50 trees planted on public property
in a town not included in the definition of municipality in subdivision 1 and with less than 1,000
population when the town applies to the county. Reforestation grants to towns and home rule
charter or statutory cities of less than 4,000 population with an approved pest control program
may include 90 percent of the cost of the first 50 trees planted on public property. The governing
body of a municipality that receives a reforestation grant under this section must appoint up to
seven residents of the municipality or designate an existing municipal board or committee to
serve as a reforestation advisory committee to advise the governing body of the municipality in
the administration of the reforestation program. For the purpose of this subdivision, "cost" does
not include the value of a gift or dedication of trees required by a municipal ordinance but does
include documented "in-kind" services or voluntary work for municipalities with a population
of less than 1,000 according to the most recent federal census.
(d) Based upon estimates submitted by the municipality to the commissioner, which state
the estimated costs of sanitation and reforestation in the succeeding quarter under an approved
program, the commissioner shall direct quarterly advance payments to be made by the state to the
municipality commencing April 1. The commissioner shall direct adjustment of any overestimate
in a succeeding quarter. A municipality may elect to receive the proceeds of its sanitation and
reforestation grants on a periodic cost reimbursement basis.
(e) A home rule charter or statutory city, county outside the metropolitan area, or any
municipality, as defined in subdivision 1, may submit an application for a grant authorized by this
subdivision concurrently with its request for approval of a pest control program.
(f) The commissioner shall not make grants for sanitation and reforestation or wood
utilization and disposal systems in excess of 67 percent of the amounts appropriated for those
purposes to the municipalities located within the metropolitan area, as defined in subdivision 1.
Subd. 9. Subsidies to certain owners.
A municipality may provide subsidies to nonprofit
organizations, to owners of private residential property of five acres or less, to owners of property
used for a homestead of more than five acres but less than 20 acres, and to nonprofit cemeteries
for the approved treatment or removal of diseased or pest-infested shade trees.
Notwithstanding any law to the contrary, an owner of property on which shade trees are
located may contract with a municipality to provide protection against the cost of approved
treatment or removal of diseased or pest-infested shade trees or shade trees that will contribute
to the spread of shade tree diseases or pest infestations. Under the contract, the municipality
must pay for the removal or approved treatment under terms and conditions determined by its
Subd. 10. Tree inspector.
(a) The governing body of each municipality may appoint a
qualified tree inspector. In accordance with section
, two or more municipalities may
jointly appoint a tree inspector for the purpose of administering the rules or ordinances in their
communities. If a municipality has not appointed a tree inspector by January 1 in any year, the
commissioner may assign a qualified employee of the Department of Agriculture to perform the
duties of the tree inspector. The expense of a tree inspector appointed by the commissioner
must be paid by the municipality. If an employee of the Department of Agriculture performs
those duties, the expense must be billed to the municipality and paid into the state treasury and
credited to the nursery and phytosanitary account.
(b) Upon a determination by the commissioner that a candidate for the position of tree
inspector is qualified, the commissioner shall issue a certificate of qualification to the tree
inspector. The certificate is valid for one year. A person certified as a tree inspector by the
commissioner is authorized upon prior notification to enter and inspect any public or private
property that might harbor diseased or infested shade trees.
(c) The commissioner may, upon notice and hearing, decertify a tree inspector if it appears
that the tree inspector has failed to act competently or in the public interest in the performance of
duties. Notice must be provided and a hearing conducted according to the provisions of chapter
14 governing contested case proceedings. Nothing in this paragraph limits or otherwise affects the
authority of a municipality to dismiss or suspend a tree inspector in its discretion.
Subd. 11. Financing.
(a) A municipality may collect the amount assessed against the
property under subdivision 1 as a special assessment and may issue obligations as provided in
429.101, subdivision 1
. The municipality may, at its option, make any assessment levied
payable with interest in installments not to exceed five years from the date of the assessment.
(b) After a contract for the sanitation or approved treatment of trees on private property has
been approved or the work begun, the municipality may issue obligations to defray the expense of
the work financed by special assessments imposed upon private property. Section
to those obligations with the following modifications:
(1) the obligations must be payable not more than five years from the date of issuance; and
(2) no election is required.
The certificates must not be included in the net debt of the issuing municipality.
Subd. 12. Deposit of proceeds in separate fund.
Proceeds of taxes, assessments, and
interest collected under this section, bonds or certificates of indebtedness issued under subdivision
10, and grants received under subdivision 7 must be deposited in the municipal treasury in a
separate fund and spent only for the purposes authorized by this section.
Subd. 13. Wood use.
The Departments of Agriculture and Natural Resources, after
consultation with the Minnesota Shade Tree Advisory Committee, may investigate, evaluate, and
make recommendations to the legislature concerning the potential uses of wood from community
trees removed due to disease or other disorders. These recommendations shall include maximum
resource recovery through recycling, use as an alternative energy source, or use in construction or
the manufacture of new products.
Subd. 14. Municipal option to participate in program.
The term "municipality" shall
include only those municipalities which have informed the commissioner of their intent to
continue an approved pest control program. Any municipality desiring to participate in the
grants-in-aid for the partial funding of municipal sanitation and reforestation programs must
notify the commissioner in writing before the beginning of the calendar year in which it wants to
participate and must have an approved pest control program during any year in which it receives
grants-in-aid. Notwithstanding the provisions of any law to the contrary, no municipality shall be
required to have an approved disease control program after December 31, 1981.
Subd. 15. Certain species not subject to chapter 18G.
Chapter 18G does not apply to
exotic aquatic plants and wild animal species regulated under chapter 84D.
