In June of 2008, new FEMA floodplain maps and reports became effective. Use this page to find view these maps and find out more about how this may have affected you.
The City of Oregon City participates in the National Flood Insurance Program (NFIP), which makes flood insurance available to everyone. The City makes continual efforts to reduce flood damage potential, which reduces insurance rates. The program was created by the Federal Emergency Management Agency (FEMA) in an effort to improve public safety, prevent property damage, and protect the natural floodplain environment. Communities that participate in this program agree to manage flood hazard areas by adopting minimum regulatory standards.
The City was officially awarded a lower insurance cost rating (Currently level 7) in part due to the fact that it participates in public outreach. We also received a FEMA Pre-disaster mitigation Grant for a seismic retrofit for Mountainview Reservoir.
FEMA Flood Maps and data:
Currently the City bases flood information on the 1996 flood inundation line and the Flood Insurance Rate Maps (FIRMs) published by FEMA. The City has these maps available at City Hall.

For more information on these flood hazard areas please contact the City of Oregon City Building Department at (503) 722-3789.
Please note that FEMA only accepts information from their published FIRM maps, and not from digital GIS data.
Flood Insurance Rate Maps (FIRMs):
The purpose of a FIRM is to show the areas likely to be inundated by a 100 year flood. FIRMs can be viewed or obtained from a variety of sources. You can determine which FIRM map you need by entering an address on this site. You can order a hardcopy FIRM Panel Map from the FEMA Map Store. You can also view an UNOFFICIAL digital version of the FEMA 100 year floodplain and the 1996 Flood Innundation lines by visiting our interactive mapping site OCWebMaps and turning on the floodplain layers, or by viewing this Adobe PDF map.
The floodplain boundaries shown on the site OCWebMaps is a digital version of the 1996 inundation line, and is currently the boundary the City uses for floodplain determination. This digital version is currently NOT official with or accepted by the Federal Emergency Management Agency (FEMA) or any other jurisdiction, department, entity, business, or individual. The City of Oregon City makes no representation regarding the completeness or accuracy of this or other data.
