City outlines flood history and mitigation steps: automated gates, buyouts and ongoing infrastructure work
Summary
Staff reviewed Garland’s flood history, recent mitigation efforts and near‑term actions: an automated low‑water crossing gate project, voluntary buyout grant applications for flood‑prone properties, and continuing drainage projects from the 2019 bond program. City urged residents to register for alerts and to keep personal emergency preparedness.
City staff presented a historical overview of flooding in Garland, recent trends and the city’s mitigation and response measures.
Staff summarized past events (including the 2015 ‘hundred‑year’ flood) and said Garland has about 94 miles of creeks and streams inside city limits. Water Utilities and Transportation staff emphasized that sanitary and stormwater systems in creek bottoms were installed decades ago and that many low‑lying creek crossings and older subdivisions were designed to standards lower than modern 100‑year criteria.
Near‑term and ongoing measures discussed included: - An automated low‑water crossing/gate project (Transportation) that will install remotely operated gates at priority crossing points (Holford Road bridge and others); the city said construction was expected to begin within weeks. - Participation in voluntary FEMA buyout programs: Garland applied to buy flood‑prone properties in 2023 and 2024; results are pending and FEMA decisions on funding were anticipated in the fall/winter cycle; the city indicated residents would be notified if offers are approved. - Capital drainage projects funded by the 2019 bond, including Montclair, Country Club Estates and Saturn Springs, designed to remove properties from the floodplain or reduce risk.
On public alerts and response, staff urged residents to use multiple channels: the National Weather Service, county river forecasts, the city’s Everbridge/Garland Alert system and NOAA weather radios. Staff noted limitations in any single notification method (cell carrier overloads, residents disabling alerts, siren reach and the difference in intended use of outdoor sirens versus flood warnings) and recommended household preparedness (three‑day supplies, cash, and personal plans) while the city develops additional monitoring and automated notification capability (IPAWS) pending federal certification.
Staff said the city performs standardized sewer and manhole cleaning and CCTV inspections in compliance with TCEQ minimums, and reminded council that aging infrastructure and storm damage can combine to create I&I issues that require targeted capital work. City staff committed to continued public outreach about preparedness and to reporting back with engineering updates and timelines for gate and drainage projects.
