Relating to the dissolution by petition of a municipal management district; making conforming changes related to ship channel security districts.

This bill changes the process for dissolving certain Texas districts by requiring property owners representing at least two-thirds of the district's taxable property value (based on county tax rolls) to petition for dissolution, instead of a simple majority. It applies to both municipal management districts (under Local Government Code) and ship channel security districts (under Water Code). The new threshold takes effect September 1, 2025, and does not apply to petitions filed before that date. Existing petitions filed under the previous law remain governed by the prior rules.
