HB 3351 Missouri House · 2026 Regular Session

Creates provisions for detachment from a water district for certain customers in certain circumstances

HB 3351 creates a process for property owners or voters in a water district to request detachment from the district under specific conditions. It requires that no outstanding bonds or debt over $25,000 exists for infrastructure, or that creditors consent to the detachment. Petitions must be signed by a majority of voters/landowners in the affected area (5+ if over 10, 50% if fewer) and filed with the court, which then reviews whether detachment benefits both the district and the detached territory. The court must approve detachment only if it serves the best interest of all parties without harming the remaining district.

What changed between versions

Introduced House Committee Substitute · 3 edits
MINOR
The bill was amended to include two related bills (HB 3351 and HB 3371) instead of just one, and the text was reorganized to remove the original introduction by Representative Costlow. The substantive policy regarding voter and landowner petition thresholds was clarified to ensure the rules apply correctly whether there are ten or fewer, or more than ten, eligible voters.
Scope change
The scope expanded to cover both HB 3351 and HB 3371, and the bill's classification was updated from 'Introduced' to 'House Committee Substitute'.
SCOPE

The bill title and numbering were updated to reflect that it now includes both HB 3351 and HB 3371, indicating a consolidation or joint amendment of two related legislative proposals.

TECHNICAL

The original introduction line identifying Representative Costlow as the sponsor was removed, likely because the bill is now a substitute version prepared by the House Committee.

REQUIREMENT

The text regarding petition signatures was restructured to clearly distinguish between scenarios where there are ten or more eligible voters versus fewer than ten, ensuring the correct threshold is applied in each case.
