Council hears $65M-plus conceptual plan to widen Henderson Road; task force recommends mix of medians and striping

Angleton City Council on Jan. 14 received a detailed briefing on a multi-phase concept to widen and improve Henderson Road, a major east-west corridor, with drainage upgrades, pedestrian facilities and intersection improvements.

Staff said the plan addresses projected growth that could add about 2,200 residential dwellings with access to the corridor. The city'hired consultant work and a task force that included the Angleton Fire Department, Police Department, Angleton ISD and neighborhood representatives. The task force evaluated alternatives including a full boulevard with a wide median, and a reduced-footprint section without medians; it recommended a mix: raised medians in higher-traffic segments and painted-only striping in others to limit right-of-way needs and cost while preserving safety.

Conceptual drainage work would enclose a large ditch, install reinforced concrete pipe (RCP) in sizes from 42 inches to 60 inches and increase drainage capacity from roughly a 20-25 year level to a 100-year standard. Staff described coordination with Angleton Drainage District and a proposed mitigation linkage to a regional detention facility (RAB Road detention). Staff said pipe/box-canal materials and inflation have driven costs up substantially, with estimates for individual phases about $22 million for Phase 1, $15 million for Phase 2, $7.9 million for Phase 3 and $11 million for Phase 4; staff presented a total-project order-of-magnitude cost in the tens of millions and included 30% contingencies in conceptual budgets.

The plan calls for an 8-foot shared-use path for pedestrians and bicycles in most sections, and 5-foot sidewalks in other locations. The task force recommended special cross sections near business and school areas — for example, smaller raised medians near 288B and Valderas, and mid-block turn lanes to serve a Tae Kwon Do studio and Angleton Middle School.

Staff noted the project scored well in the HGAC TIP competitive process (Henderson scored an 84 on the written portion and a 1.5 cost-benefit metric), which could make the city eligible for a match of about 80% of project cost through regional funding. Staff recommended the council move forward with prioritized right-of-way acquisition in targeted locations and continue pursuing HGAC funding and hydraulic modeling to determine mitigation-volume requirements at the regional detention facility.

Council asked about phasing, right-of-way impacts and median continuity; staff said the current approach reduces required acquisitions and lowers cost while maintaining safety priorities. Staff suggested the city begin property acquisitions in selected locations because land procurement often takes the longest time. No formal action was taken; staff said they would return with design and funding steps and continue stakeholder coordination.
