AI Flood Sensors Arrive in Galveston County

Galveston County Consolidated Drainage District has put a new flood-warning network online in Friendswood and League City, adding AI-linked sensors that officials say are meant to give residents and emergency responders earlier notice when water starts rising. The system was reported publicly on May 20 and follows an April rollout in the county, according to local news reports, district materials and a government technology publication. (click2houston.com) Seven sensors are installed in Friendswood and League City, according to Click2Houston, while district project materials and the pilot contract describe an eight-sensor program approved in 2025. (click2houston.com) The district’s April blog post said it had begun installing eight sensors across its jurisdiction, suggesting the public-facing rollout may still be moving from pilot buildout to full operation. Jason Jones, secretary of the district board, told Click2Houston the system was an “obvious step in the right direction” because Galveston County previously had no flood sensors. Alison Reese, co-founder and chief operating officer of Simplicity Integration, said the goal is to give communities more lead time before conditions become dangerous.

Friendswood and League City are the first locations in the county network, with six sensors in the Clear Creek watershed and one in the Dickinson Bayou watershed, according to Click2Houston. The district’s jurisdiction covers more than 20 square miles in northern Galveston County and includes more than 80 miles of creeks, ditches and bayous. (click2houston.com) Government Technology reported that contract materials listed proposed sites including Chigger Creek at Friendswood Trail, Chigger Creek at Oak Drive, Steven’s Park, Clear Creek, Mary’s Creek at Devil’s Dip, Mary’s Creek at Winding Road and Bakers Road at Cowards Creek. Those locations place the pilot in neighborhoods that drain toward Clear Creek and adjacent tributaries. (click2houston.com) ### What makes this an AI system instead of a standard flood gauge? Simplicity Integration said the network combines live sensor readings with rainfall totals, stream-gauge readings, weather-station data and soil-saturation conditions. Click2Houston reported that the platform then uses artificial-intelligence tools to analyze those inputs and help predict how flood conditions could develop. (click2houston.com) Axonis Decision Intelligence and Simplicity said the flood-intelligence system, called SI-Ai, is powered by Axonis and can combine sensor, weather, water-level and infrastructure data into one operating view. Government Technology reported the system can also be configured to trigger alerts and activate infrastructure such as sirens, warning lights and barriers.

Click2Houston reported that residents can use a public web portal to monitor sensor locations in real time and sign up for alerts tied to specific creeks or monitoring points. The station said the map uses color-coded indicators to show flood conditions, giving residents a quick way to judge whether water is rising toward more dangerous levels. (click2houston.com) GCCDD also maintains public flood-sensor and alert sign-up pages on its website. Those pages are the district’s public entry points for checking conditions and subscribing to official alerts. ### How much is the pilot costing the district? The Galveston County pilot agreement totals $49,500 for eight smart water sensors, installation, maintenance and data services, according to Government Technology. (insider.govtech.com) The same report said the district board approved the agreement with Simplicity on Sept. 9, 2025. Ongoing data service is priced at $23 per month per sensor, billed annually at $276 per sensor, Government Technology reported. Annual maintenance after the first year is listed at $100 per sensor.

Paige Bailey, the district’s chief executive and general counsel, wrote in an April 23 district blog post that the sensors were part of a districtwide effort to provide residents better real-time data during flooding events. (gccdd.dst.tx.us) Click2Houston reported that district leaders want to expand the system across Galveston County to help residents and officials make evacuation and route decisions during severe weather. Galveston County Office of Emergency Management is already promoting 2026 hurricane preparedness resources on its website, and the drainage district’s next public-facing step is likely continued use of its flood-sensor map and alert system as more locations are added. (insider.govtech.com) The district’s public project page describes the flood gauges as a pilot program, indicating additional deployment decisions remain ahead. (gcoem.org) (gccdd.dst.tx.us)
