Missouri City holds public hearing on Sienna thoroughfare plan; staff seeks feedback on short-, medium- and long‑term options

Missouri City officials held a joint public hearing April 27 to solicit feedback on proposed amendments to the city's Major Thoroughfare Plan for the Sienna area. City Engineer Vincenzo Carraza said the draft lists short‑term (1— years), medium‑term (5—0 years) and long‑term (10'0 years) concepts to improve mobility and emergency access, and that the presentation tonight was for public input only; no action was taken.

Carraza said the short‑term concepts include a bridge over the Gulf Coast Water Authority canal and two segment extensions, medium options would use existing roadways and fill small construction gaps and the long‑term vision contemplates a Brazos River connection that would require additional study. "We're here to obtain public feedback and next steps," Carraza said. He emphasized that the plan amendment is a visionary document and that conceptual studies, right of way analysis and funding identification would come later.

Residents from multiple Sienna neighborhoods urged caution, arguing that several proposed connectors would push high volumes of daily traffic onto streets that were not built for through traffic. "To route thousands of cars through a residential street barely two lanes wide would absolutely be a nightmare for us," said Elijah Gilbert, a London Lane resident who supplied traffic-count overlays indicating peak volumes near HEB on Sienna Parkway. Other speakers pointed to choke points at Darby and South Post Oak, drainage and wetlands constraints, and proximity to the airport and railroad as complicating factors.

Council members and commissioners pressed staff for more data and for a clearer separation of routes intended for daily circulation from those intended for emergency or gated evacuation use. Commissioner Salloway requested that each proposed segment be labeled in the studies by intent (emergency vs. daily traffic) and asked that staff include safety modeling in the conceptual studies; Carraza and Assistant City Manager Shashi Kumar said traffic modeling and safety analyses will be completed after the plan amendment and sharper concept selection.

City Manager indicated that project costs are not yet defined and that funding discussions will follow. The item is scheduled for a Planning & Zoning Commission recommendation on May 13, followed by City Council consideration (tentatively May 18 and June 1), with staff to return with traffic modeling, funding scenarios and refined options. "This is our chance to speak," Mayor Pro Tem said, asking staff and commissioners to weigh neighborhood impacts alongside mobility needs.

The meeting record indicates staff will continue stakeholder coordination with Fort Bend County and TxDOT on widening FM 521 and other regional projects that intersect with city options. The planning effort will include conceptual engineering, right‑of‑way assessment, environmental constraints and public engagement before any construction funding is sought or commitments made.
