The overview
Sienna Parkway is one of the city’s most traveled and congested roadways, spurred by the continued growth in Missouri City’s extraterritorial jurisdiction, Shashi Kumar, Missouri City’s director of public works, said in a recorded video at the State of the City event Sept. 19.
More than 11,000 single-family homes are occupied in Johnson Development’s 10,500-acre Sienna community, which will have more than 15,000 homes by its estimated 2032 build out, said Alvin San Miguel, senior vice president of Johnson Development.
With this future growth planned, officials with Johnson Development, Missouri City, Fort Bend County and local utility districts are discussing several mobility options to prepare for it, San Miguel said.
“We believe we need to be working on additional improvements to Sienna Parkway,” he said. “They could take five to six years to complete. We should certainly start on them in 2024-2025 and that way by build-out—close to 2030—all of these improvements are in place to be able to have the capacity for the community.”
The details
One project to address mobility includes adding third lanes to six intersections between McKeever Road and Highway 6, San Miguel said.
Four intersections have been completed, with the most recent wrapping up in mid-October. These intersections are:
- McKeever Road
- Sienna Ranch Road
- Watts Plantation Road
- Sienna Springs Boulevard
However, inflation has pushed the project costs higher since their design, so funding for the projects isn’t secured, San Miguel said. The projects are jointly funded by Missouri City, Fort Bend County and the Sienna Management District.
What’s next
Meanwhile, discussions are also ongoing to determine other ways to improve traffic flow along the corridor, San Miguel said.
He said options engineers and stakeholders are considering include:
- Expanding Sienna Parkway from four to six lanes between Highway 6 and FM 521
- Replacing some intersections with roundabouts to ease traffic flow
The project is still in the conceptual planning phase, so there's not yet a funding mechanism in place for the non-developer portion of improvements, he said. However, he noted the county is exploring funding options, and officials with local municipal utility districts and levee improvement districts have said they're able to contribute to the project cost.
