Missouri City officials are moving toward a vote that would fold Sienna Municipal Utility District No. 3 into the city, a change that could reshape how homeowners there pay for everything from policing to garbage pickup. A homeowner in the district has already raised concerns about the proposed annexation, according to a report from FOX 26 Houston reporter Leslie Delasbour. The vote is tentatively scheduled for Dec. 7.
The annexation would apply only to Sienna MUD No. 3, according to Community Impact, which reports that Missouri City officials will soon vote on making the district part of the city. If approved, residents would pay the city's property tax rate instead of the MUD rate, and city property tax bills would start arriving in fall 2027, per the same report. The proposal also calls for fire-service fees and the introduction of garbage collection fees and city utility rates, financial changes that would land on top of the new tax structure.
Policing and street upkeep would shift to the city as well. Community Impact reports that Missouri City Police would take over local policing duties in the district, while the city would provide street maintenance, repairs and code enforcement there. Missouri City hosted an informational town hall Tuesday night at 7 p.m. to walk residents through the proposal, the outlet notes.
City Says the Math Should Work Out
City officials have offered their own financial framing for the deal. A notice from the City of Missouri City states that the goal is to strengthen long-term municipal-service, infrastructure and public-safety planning, and that annexation is not expected to have a negative fiscal impact on the city after accounting for additional revenue and the costs of providing services, maintaining infrastructure and assuming district debt. That assessment, labeled by the city as based on staff's financial analysis, addresses the city's side of the ledger rather than what individual Sienna MUD No. 3 households might pay.
The 2001 Strategic Partnership Agreement between Missouri City and Sienna MUD No. 3 provides the framework for the current annexation proposal.
A Playbook From Sienna MUD No. 2
This would not be Missouri City's first attempt at folding a Sienna district into the city. Council voted 5-2 in September 2023 to approve the annexation of Sienna MUD No. 2, adding roughly 1,600 homes and nearly 6,000 residents, according to Community Impact's reporting at the time. That earlier process drew pointed questions from both residents and council members about cost and preparedness.
Residents worried about an added financial burden because the city would not actually receive tax revenue from the newly annexed district until Oct. 1, 2024, the outlet reported. Council Member Jeffrey Boney raised concerns about integrating Sienna MUD No. 2's debt and the possibility that residents could keep paying for MUD-specific services even after the switch. One homeowner told Click2Houston during that debate that the process was moving too quickly, saying “It's going way too fast for what it should be,” according to Click2Houston, which also reported that Sienna MUD No. 2 included just over 1,600 households at the time.
On the service side, the city tried to get ahead of concerns about police coverage. Police Chief Brandon Harris said at the time that Missouri City planned to establish a new police substation near Highway 6 and Fort Bend Parkway specifically to improve response times in the newly annexed area, the station's report noted.
What Sienna MUD 3 Homeowners Don't Yet Know
For now, Sienna MUD No. 3 residents are working with limited specifics. The dossier of public reporting does not include a proposed city tax rate, the district's current MUD rate, or household-level estimates of how bills might change under annexation. The dollar amounts for the proposed fire-service, garbage and utility fees have likewise not been published, and it remains unclear how many households or residents live within Sienna MUD No. 3's boundaries.
It is also not yet established whether residents will get a direct vote on the MUD No. 3 proposal, separate from the City Council's own scheduled decision. With the informational session now held and the council's tentative Dec. 7 vote approaching, homeowners in the district are left watching how closely this annexation will track the contentious rollout that played out with their Sienna MUD No. 2 neighbors three years ago.
