Kerr County leaders are set to decide whether the Guadalupe River will soon have its own chorus of flood sirens, as commissioners meet today on a plan for permanent warning systems in the wake of last summer's devastating floods. The proposal would place sensors and sirens in key low-lying spots and create a public monitoring platform so campers, residents and first responders get faster, clearer alerts when the water starts rising.
At a 9 a.m. meeting in Kerrville, commissioners will consider entering an interlocal agreement with the Upper Guadalupe River Authority to roll out an outdoor flood-warning system and explore watershed protection measures, according to FOX San Antonio. The discussion is expected to cover which areas flood most often, how to craft best-management practices for when and how alerts sound, and what backup power and communications systems are needed so warnings stay reliable during outages.
State lawmakers folded the effort into Senate Bill 3, and the Texas Water Development Board has accelerated SB3 implementation so affected counties can move quickly to tap grant money and technical guidance, the agency said in a December press release. The TWDB plan calls for mapping flash-flood-prone areas and publishing best practices for outdoor sirens and gauge networks as local governments prepare their systems.
How the system would work
Project planners are looking at a network that blends National Weather Service forecasts with real-time data from gauges across the Guadalupe watershed; when certain thresholds are met, the system would post alerts on a public website and trigger outdoor sirens and flashing flood signs in affected zones, The Texas Tribune reports. The goal is to send targeted warnings to camps, RV parks, volunteer fire departments and low-water crossings instead of a single blanket alarm for the entire county.
Timeline, cost and local funding
Kerr County's project team has estimated the full system could cost roughly $5 million and aims to provide at least 15 minutes of lead time when floods are predicted, project lead Tom Moser told KSAT. Local officials are already shifting money around to get things going: the San Antonio Express-News reported that the Upper Guadalupe River Authority has reallocated about $1.5 million from reserves to jump-start early work on sensors and a public “viewer” dashboard.
How quickly the network takes shape will depend on whether commissioners approve the interlocal agreement and how fast the state grant paperwork moves, county officials say. Today's meeting begins at 9 a.m., and residents looking for updates can follow local coverage or check the county and UGRA websites for agendas and posted notes, FOX San Antonio reported.
