Be aware of where not to drive this flood season

water over roadway

Never drive past barricaded road signs, or where there is water over the road -- driving through rushing water is the number one cause of loss of life during floods. If your car stalls in a flooded area, abandon it as soon as possible and walk to safety in the direction you came from.

As the winds of November head into the Puget Sound, so does the heavy rain. This is the time of year when King County is prone to heavy flooding, and the flood season can last well into early spring.

Flooding can occur near major rivers, small creeks and normally dry ditches. But what is called "urban flooding" can also happen in subdivisions, parking lots and city streets. You don't have to live on the banks of the Snoqualmie or Cedar rivers to experience significant flooding in King County.

Your best defense is to be prepared. If you are new to the area, ask neighbors and friends if you are living in a flood-prone area. You can also call the King County Department of Development and Environmental Services at (206) 296-6660 for information.

Have an emergency plan for your entire family that can be used in the event of a flood, severe winter storm or other major natural disaster. Establish a central meeting place in case your home is inaccessible.

Just because your home or workplace is on high ground, doesn't mean it won't be cut off by rising waters. Look at the roadways along your daily route and have a travel alternative identified that avoids low-lying areas, underpasses and other places that could be flooded by either nearby waterways or heavy rains.

Never drive past barricaded road signs or where there is water over the road -- driving through rushing water is the number one cause of loss of life during floods. If your car stalls in a flooded area, abandon it as soon as possible and walk to safety in the direction you came from.

Around your own home, keep street drains and storm grates free of leaves and other debris. Call the King County Road Services Division at (206) 296-8100 or 1-(800) KC ROADS, if you need assistance and live in unincorporated King County.

The Road Services Division has identified some specific roads that serve as indicators of how severe the flooding is. For example, during minor flooding (Phase II) Neal Road, Reinig Road, West Snoqualmie River Road, Snoqualmie Meadowbrook Road and Mill Pond Road could all be overtopped when the Snoqualmie River overflows its banks.

In a moderate flood (Phase III), the Green River frequently spills over onto Southeast Green Valley Road and West Valley Road, and the Cedar River is a problem on Lower Dorre Don Road and Byres Road.

In the event of extreme flooding (Phase IV), many major roads in east and south King County are threatened by both water over the riverbanks and leaking levees, mud slides and debris piling up under bridges.

To monitor roadway conditions during floods and storms, visit the King County Alert Road Closures and Conditions Web page. You can also subscribe to King County Alert and be notified by e-mail or page about the latest road closures and travel conditions.

Comprehensive flood information is available online through the King County Department of Natural Resources Web site, and regionally on the Taking Winter By Storm Web site.
