July 12 open house to share flood map data

Ongoing county Flood Risk Survey ends July 15

Those who live in Upper Sandy River Basin communities and have flood-related concerns might want to take note of an upcoming open house and an ongoing online survey, both offered by Clackamas County.

The open house is being held at 6 p.m. on Tuesday, July 12, at the Mt. Hood Lions Club, 27430 E. Woodsey Way in Welches.

The event is in response to new preliminary maps issued by the Federal Emergency Management Agency (FEMA) showing revisions to the 100-year floodplain along the Sandy, Salmon, and Zigzag rivers and nearby creeks. The public is invited to the open house to view the maps and discuss the draft map revisions.

The maps are important because they are used to help community officials and area residents identify flood risks. When officially adopted, they’ll also be used for flood insurance, land use and development decisions.

The flood maps currently in place use data dating back to the 1980s, said Steve Hanschka, the county’s flood plain manager. For more information on the open house, call 503-742-4500 or email This email address is being protected from spambots. You need JavaScript enabled to view it..

Also, the county’s Flood Risk Survey is taking place online through July 15. Through the survey’s results, county planners hope to learn more about residents’ feelings and attitudes towards the risk of flood impacts and dangers in the Upper Sandy River and its tributaries.

“We wanted to get a pulse from the community members up there,” said Jay Wilson, resilience coordinator for the county’s emergency management department.

The survey takes about 10 to 20 minutes to complete, and is especially geared to property owners in the Brightwood, Marmot, Welches, Wemme, Rhododendron and Zigzag communities. However, residents do not need to live near a river to take part in the survey.

The survey can be taken online at clackamas.us/emergency/floodsurvey.html. Upon completing the survey, participants have the option of entering to win a $50 gift card.

For those without internet access or those who would prefer to complete a paper survey, representatives from the county will have laptops and paper surveys available at 10 a.m. on Friday, July 15, in front of the Hoodland Thriftway at 68280 Highway 26 in Welches.
