Full Breakdown

005, the Missouri Register's "Noxious Weed List" (Vol. 48, No. 16, August 15, 2023). 130(A) declares any such violation a public nuisance subject to abatement and prosecution, reaching land between the property line and the centerline of an adjacent street or alley, sidewalks, easements and rights-of-way included. 110 state that eradicating Noxious Weeds protects the City's environmental health and prevents degradation of natural and maintained landscapes, erosion, destroyed wildlife habitat and diminished property values. 140, who issues a written notice of violation giving the Owner, Occupant or Agent ten days to abate before the City steps in.

Frequently Asked Questions

How does Overland Park decide which weeds are noxious?
Section 7.20.120(G) defines Noxious Weeds by reference to the Kansas Administrative Regulations Section 4-8-44 Category A, B and C list, and also incorporates Missouri's noxious weed list at 2 CSR 70-45.005, so both state lists can trigger a violation on Overland Park property.
What happens after I get a noxious weed notice?
Section 7.20.140 requires the notice be sent by certified mail or personal service, giving you ten days to abate the weeds yourself. You can request a hearing before the deadline; if you miss it, the City abates the weeds and assesses the cost, plus a fee, against the property.
Can I be fined in addition to paying abatement costs?
Yes. Section 7.20.180(B) states prosecution of an offender does not limit the City's right to also pursue collection of abatement costs, so a Municipal Court fine and a cost assessment can both apply to the same violation.
Does the noxious weed rule apply only to backyards?
No. Section 7.20.130(A) extends the prohibition to the area between the property line and the centerline of any adjacent street or alley, covering sidewalks, easements and rights-of-way abutting the property, not just the fenced yard.
