Reliable flood forecasting and early detection of flood conditions are critical components of an effective local flood warning system.  Several hours of advance warning of impending floods can prevent extensive property damage; minutes of advance warning can save lives.

The City of Leon Valley’s three monitoring stations include all the remote site equipment and a central Base Station.  Their system is ideally suited for applications requiring instantaneous retrieval of environmental data – measurements of rainfall and water levels in streams, creeks or other bodies of water.  It is solar powered and designed to work during extreme weather events.  The system is also capable of expanding to include hardware for high water detection to warn drivers that the road section ahead is flooded or impaired (via flashing lights and/or automatic barrier gate).

The Base Station software helps facilitate data management:  graphical map displays, activation of alarms, instant messaging, hydrological forecasting and analysis tools.  The software package is an easy-to-use, menu-driven program and is capable of feeding public or intra-agency web sites.

Periodic maintenance is key to the systems’ performance and the City contracts with their hardware supplier for regular preventative maintenance.  This maintenance keeps the equipment operating within factory specifications year round. 

Citizens that live in or near the Special Flood Hazard Area may receive automatic text alerts to cell phones. These alerts will be in response to rising flood waters and provide early notification. You may contact Assistant Fire Chief Eric Burnside at e.burnside@leonvalleytexas.gov or at 210-684-3219 and request to be added to the system or fill out the enclosed application  and email to the Assistant Fire Chief.
