Seaside Flood Warning System
Description

ODOT installed a flood warning system on Highway 101 near Seaside. This system warns drivers of water on the roadway and also reduces the need for ODOT maintenance personnel to monitor water levels at this location. The system is composed of a level sensor at the low point in the road connected to a series of advance warning signs at each end of the problem section.  The sign for southbound traffic is located at milepost 22.66, while the sign for northbound traffic is at milepost 23.54.  Flashing beacons are activated when flood conditions are imminent.  The system transmits water level data to district offices so that maintenance personnel will be able to respond or be prepared to respond when conditions warrant.  This data is also made available to the public via www.tripcheck.com
 
 
Similar flood warning systems can be found across the country.  For example, a similar system was installed in Dallas, Texas, improving roadway safety for motorists.  Another flood warning system installed by the city of Palo Alto, California, has proved to be useful to both emergency management personnel and motorists.    For more information see the reference links below.
