City engineer presents short-, medium- and long-term route options for Sienna Parkway

City Engineer Vincenzo Carraza told the Planning and Zoning Commission the May 6 workshop was to "workshop changes to the mobility master plan, specifically as pertains to Sienna Parkway" and to prepare a package for action on May 13 and City Council consideration thereafter. He provided a three-tiered approach: short-term (1–5 years), medium-term (5–10 years) and long-term (10–20 years) route concepts.

In the short term Carraza identified the Bee's Passage bridge over the Gulf Coast Water Authority canal, reconnecting Old McKeever Road to State Highway 6, and a Miller Road connector that would provide a southern entrance with a future link to the TxDOT-proposed SH 99 corridor. He said the map shows approximately 20,000 homes in the city limits and roughly 15,000 homes in the extraterritorial jurisdiction in the Sienna area, underscoring significant mobility needs. For the medium term staff proposed two North–South alternates (labeled Alternate 1 and Alternate 2) that use a mix of existing rights-of-way and potential interjurisdictional lines; Carraza noted the city of Arcola already has a 60-foot right-of-way in one area that could be leveraged. The long-term Western ETJ connector would cross the Brazos River and require multi-agency coordination, placing it in a 10–20 year timeframe.

Carraza emphasized the presentation was conceptual: "This is the overall map of the Sienna area... Tonight's item just amends or updates the plan focusing on the Sienna area." He outlined subsequent steps as feasibility studies, securing funding, right-of-way acquisition, and design and construction.
