Along with the Willamette River, Marion County has many streams and rivers that are subject to flooding. The storms from Dec. 1996 through Feb. 1997 showed how rain and melting snow can cause these streams and rivers to overflow. As you can see from these pictures, homes and property suffered significant damage:
Willamette River overflowing, south of Salem
City of Keizer area that flooded
Pudding River overflowing
The purpose of Marion County's Floodplain Program is to minimize public and private losses due to flood conditions. To benefit our citizens, the County participates in the National Flood Insurance Program (NFIP). This program makes federally-backed flood insurance available for eligible buildings, whether they are in the floodplain or not. Generally speaking, a floodplain is level land that may be submerged by floodwaters.
The County's participation in the
Community Rating System brings many benefits to County residents. This includes flood insurance premium savings. Flood insurance covers losses caused by flooding and local drainage problems. See below for more information.
The Marion County Planning Division provides information on a variety of flood-related issues. Staff can tell you if a property is in a flood hazard area, regulations for development and flood insurance data. We can also provide copies of elevation certificates (if applicable).
Development Not Requiring an Elevation Certificate
Unless requested by FEMA, elevation certificates would not be required for the following uses:
Water dependent uses, such as boat ramps, docks, wells and well covers.
Improvements resulting from cut or fill operations, such as berms, bank improvements, ponds and dams.
Small scale facilities necessary to serve other uses, such as kiosks and open picnic shelters.
Grading, such as for roadways, even where alteration of topography occurs.
