title
Transmittal by the Flood Control District of a white paper identifying potential tunnel pilot projects along Buffalo Bayou and Greens, Halls, and Hunting Bayous, including high-level scope, delivery and funding strategies, and benefits.
end
Background and Discussion:
Following April 10, 2025, HCCC directive, the Flood Control District developed a white paper identifying pilot project options using deep tunnel conveyance for flood mitigation along Buffalo Bayou and Greens/Halls/Hunting Bayous.
This white paper evaluates conceptual segments, delivery methods, benefits, estimated costs, funding opportunities, timeline, and implementation considerations including environmental permitting and ROW acquisition.
Expected Impact:
Potential for significant flood risk reduction, improved regional stormwater management capacity, reduced construction footprint relative to surface channels, and acceleration of long-term tunnel system implementation through early pilot testing and institutional knowledge gain.
Alternative Options:
Alternative options include using traditional open-channel improvements or waiting for full-scale tunnel system implementation without pilot testing. These options could pose higher community/environmental impacts or defer institutional learning and interim flood mit...
