2001 - 2002 LEGISLATURE
February 5, 2002 - Introduced by Senators Plache and Schultz, cosponsored by
Representatives Kreuser and Gunderson, by request of William Neuhaus of
Union Grove, Wisconsin. Referred to Committee on Insurance, Tourism, and
Transportation.
SB423,1,2 1An Act to create 86.035 of the statutes; relating to: mowing highway
2rights-of-way and granting rule-making authority.
Analysis by the Legislative Reference Bureau
Under current law, the department of transportation (DOT) is authorized to
conduct maintenance activities within the right-of-way of any highway under its
jurisdiction (highway right-of-way). These maintenance activities include mowing
grass and weeds within the highway right-of-way.
This bill imposes certain limitations on DOT's authority to mow grass and
weeds in highway rights-of-way. The bill permits DOT to mow highway
rights-of-way only from July 1 until September 15 of each year. DOT may not mow
highway rights-of-way to a height of less than six inches. DOT also may not mow
highway rights-of-way beyond the closer of 12 feet from the outer edge of the
shoulder of the roadway or the bottom of any ditch adjacent to the shoulder of the
roadway, except that DOT may mow grass and weeds that obstruct the vision of a
driver or that otherwise pose a risk to the safety of persons using the highway. The
bill further requires DOT to conduct mowing operations in a manner that, to the
greatest extent possible, avoids causing damage to turf and desirable vegetation.
The bill also contains exceptions to the foregoing limitations on DOT mowing
authority for: areas to be used in connection with the establishment or maintenance
of permanent vegetative cover or a native plant community; newly seeded grassy
areas; areas designated by rule by DOT as having specific vegetation management
plans; and, as established by rule, noxious weeds and nuisance weeds. The bill
further provides that DOT must establish by rule procedures for mowing grass and
weeds in highway rights-of-way.

For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.
