Council adopts expanded erosion protections for Colorado River below Longhorn Dam
Summary
The City Council approved a code change extending the erosion-hazard buffer along the Colorado River downstream of Longhorn Dam from 100 to 200 feet and added drainage provisions to help limit future bank erosion, measures city staff and East Austin advocates said will reduce costly repairs and protect communities.
The Austin City Council on Thursday adopted an ordinance that expands erosion-zone protections along the Colorado River below Longhorn Dam, a move city staff and East Side advocates said will reduce bank erosion, protect nearby neighborhoods and lower future repair costs.
What the council approved: The ordinance amends land-development code provisions to increase the erosion-hazard zone (EHC) from 100 feet to 200 feet in specified sections of the river downstream of Longhorn Dam and clarifies drainage and construction rules intended to reduce erosion risk.
Why it matters: Speakers and staff said the lower Colorado River east of the dam flows through more erodible, sandy soils than the rocky terrain upriver, and that previous regulations provided less protection on the East Side. Councilmember Jose Velasquez, who sponsored the motion, said the change will align protections east of I-35 with those already in place to the west.
Community voices: East Austin advocates and local conservation groups supported the ordinance. Marianne Sanchez, a community organizer, said the expanded zone will protect both homes and river habitat and save the city money on recurring repairs. Susana Almanza of PODER and other neighborhood activists told council the expanded protections address long-standing environmental justice concerns about uneven protections east and west of the river.
Staff explanation: Watershed Protection staff said the measure clarifies erosion hazard rules, defines new proximity zones and adds measures for stormwater and erosion controls for new development. Manager Jorge Morales described the change as a necessary step to prevent rapidly escalating repair costs: "The protections outlined by the ordinance will not only keep current and future surrounding communities safe and prevent any further property loss, but additionally save the city millions of dollars in erosion repairs," one speaker said summarizing technical testimony.
Next steps: Council adopted the ordinance after public hearing testimony and indicated staff would continue to refine maps and guidance for implementation. The ordinance also directs staff to incorporate improved drainage and erosion-control standards into project review in affected areas.
Speakers and supporters: The item drew support from East Side organizations, land-stewardship advocates and residents including Marianne Sanchez (BODER), Valeria Menard (Colorado River Conservancy/PODER) and Susana Almanza; Councilmember Jose Velasquez made the motion to adopt the ordinance.
