Update on Flooding and Road Conditions in Corvallis and Benton County


As of 6:30am, Friday, January 20, 2012, Corvallis and Benton County are receiving a momentary break in rain fall, allowing some flood waters to recede. 

The following conditions are still in effect: 

  • SE 3rd St. (Highway 99W) remains closed between SE Crystal Lake Dr. and SE Alexander Ave.  There is no estimate from ODOT when the highway might re-open. ODOT is in the process of opening a detour around SE 3rd St. using SE Crystal lake Drive accessed off of SE Alexander Ave. 
  • Highway 34 remains closed due to a landslide at milepost 47.  There is no estimate from ODOT when the highway might re-open.
  • The NW Rosewood Dr. Neighborhood affected by a landslide on January 11, 2012, remains closed and the 22 residences remain evacuated.  No additional homes are reported damaged at this time, however, the potential for continued movement of the soil remains. 
  • A land slide continues to block the road on NW Niagara Drive in Benton County.
  • Avery Park is closed to all traffic at SE Allen Ave and at SW 15th St. and SW Philomath Blvd.  
  • SE Airport Rd is closed to all traffic from Muddy Creek Rd, mp 2, to Highway 99W in both directions. 
  • The water has receded and cleared from the NE Lancaster St. and NE Oxford Cir. area of Corvallis.  City crews worked through the night cleaning storm drains clogged by debris in fast rising water conditions in an attempt to keep water from rising again from additional forecasted rains. 


A complete listing of current road conditions in Corvallis and Benton County can be located by high water and flooding.  The current list of high water locations can be found by going to the City of Corvallis website at www.ci.corvallis.or.us/hazards or the Benton County Public Works Site www.co.benton.or.us/pw/index.php.  Residents can also call a Benton County Public Works information line at 541-766-6821 to report problems.  An information line at 541-766-6120 is available to residents of the city and county to call for updated information regarding flooding, road closures, and travel restrictions. 

All public safety entities in Corvallis and Benton County would like to remind drivers to exercise caution driving on the streets and highways in Corvallis and Benton County.  Be on the look-out for police officers and flaggers directing traffic in the area, especially in the hours of darkness. Do not drive into standing water since it is difficult to gage the depth, and vehicles can be swept away in less than 2 feet of water.

Additional rains and high winds (up to 50mph) are forecasted for the Willamette Valley starting this Friday at about 10:00pm.  This creates an increased risk of additional flooding and falling trees due to soil saturation.  The increased risk of falling trees also increases the risk of power outages from trees falling over power lines.  Corvallis and Benton County Emergency Responders encourage all citizens have food, water, and other supplies available in the event of power outages.
