The Texas Municipal League Intergovernmental Risk Pool (TMLIRP) has selected the City of Sugar Land’s Integrated Stormwater Management Model System (ISWMM) to be the recipient of their Partnership Award. The award is given to a member city of the Texas Municipal League in recognition of their contributions to both their residents and the TMLRIP.
Initially developed in 2010, ISWMM has undergone many additions and updates. Most recently, the city completed the phase three update, which included the newest generation of ponding maps for various storm durations and frequencies for the entire city. Further, the newest update saw the development and hosting of a real-time online map, available to residents, that collects and stores rainfall data and shows ponding based on real-time rainfall and storm durations.
By implementing ISWMM, Sugar Land is actively protecting its residents from flooding with state-of-the-art, up-to-date information on ponding and flooding. ISWMM is connected to 28 gauges across the city that report real-time information that is used to create ponding maps. As a result, the system gives:
- public access to real-time ponding information;
- the ability to send notifications about ponding, street flooding, and potential street closures;
- assistance in the planning of evacuation routes; and
- assistance in evaluating current drainage infrastructure to more efficiently target drainage improvements.
“I’m proud of the work that the city has done to keep our residents safe from major flood events,” said Senior Engineering Manager Jorge Alba. “ISWMM is an innovative tool that other member cities of TML can implement within their own communities, so I’m glad that this award reflects that.”
The implementation of this technology is part of a larger investment the city is making in drainage improvements, a top priority identified by Sugar Land residents through the 2020 Citizen Satisfaction Survey.
