ASSEMBLY SUBSTITUTE AMENDMENT 1,
TO ASSEMBLY BILL 579
January 9, 2024 - Offered by Representative Wittke.
AB579-ASA1,1,3 1An Act to renumber 30.122; to amend 30.122 (title); and to create 30.01 (1h),
230.122 (2), 30.122 (3), 30.2034, 30.2039 and 885.335 of the statutes; relating
3to:
use of fill in commercial waterways and Great Lakes waters.
Analysis by the Legislative Reference Bureau
This bill provides several methods for establishing the lawful public or private
use of fill placed on the bed of the Great Lakes and certain rivers and harbors.
Historic fill in commercial waterways
The bill applies, in part, to fill placed prior to 1977 that created land above the
ordinary high water mark of a commercial waterway, which is a specified list of
rivers. If the fill is unauthorized fill for which the Department of Natural Resources
has not initiated an enforcement action or is within an authorized bulkhead line and
not specifically restricted by a submerged land lease, the fill is considered land held
in private fee title ownership and is not subject to a navigational servitude.
Development of Great Lakes waterfront property
The bill provides that a city or village (municipality) may create a waterfront
development plan with respect to parcels that may have been part of the submerged
bed of a Great Lakes water at the time of statehood. The municipality must submit
required information to DNR, including a map of the parcels and a plan for
development of the parcels that details any public and private uses. Following a

public notice and comment period, DNR must determine whether the plan is
approved. DNR may not approve a plan unless it determines that 1) the plan
contains the required elements, 2) proposed private uses are not inconsistent with
existing lake bed grants or submerged land leases, 3) the amount and location of
proposed public use areas are appropriate to protect public interests, or 4) the plan
contains sufficient provisions to ensure that the public uses proposed in the plan will
be implemented and perpetually maintained.
Amendments to existing approvals
The bill provides that a municipality may apply to DNR to amend the uses
allowed within an area of a Great Lakes water that was filled pursuant to a fill
authorization granted by the legislature or a submerged land lease. DNR must
review the proposed uses based on several criteria that generally consider whether
the proposed uses are consistent with the public interest. Following a public notice
and comment period, DNR must approve the plan unless DNR determines that the
specified criteria were not met.
Claims relating to possession or title
The bill prohibits any claim or counterclaim in an action relating to the
possession or title of any real estate if the claim or counterclaim is based on an
assertion that the property includes portions of land that may have at one time been
submerged beneath a Great Lakes water if 1) the property is upland and the use of
the land has not materially changed, 2) the property is held in fee title ownership as
determined under a Great Lakes waterfront development plan, 3) the property is
held in fee title ownership based on being separated from a Great Lakes water, or 4)
use of the property has been approved by DNR as an amended use.
