FEMA Floodplain Changes
The City of Oregon City uses the combination of the 1996 floodplain inundation line and FEMA's 100-year floodplain as the basis for determining flood hazard. This document is meant a resource for determining if your property will change floodplain designation with the new FEMA maps effective June 17, 2008.
Of the 280 tax lots presently affected by floodplain determination, 2 are in the current FEMA 100-year floodplain, and will not be in the 2008 floodplain. They are:
Of the tax lots not presently affected by floodplain determination, 14 will be in the 2008 FEMA 100-year floodplain. They are:

- What factors determine flood insurance premiums?
A number of factors determine premiums for National Flood Insurance Program (NFIP) flood insurance coverage. Major factors include the amount of coverage purchased; the deductible and the location, age, occupancy, and type of building. For newer buildings in floodplains, the elevation of the lowest flood relative to the elevation of the 1% annual-chance flood can also be used to rate the policy.
- My house was not in a floodplain according to the old map, but the new map shows it as being in a floodplain. Will I have to purchase flood insurance now?
If you have federal or federally related financing for the property in question and you do not already have flood insurance, your lender may contact you once the new map takes effect and require that you purchase the insurance. If you do not purchase flood insurance within 45 days after being informed that flood insurance is required, the lender can force place the insurance and charge you for the cost of it.
If you dispute the lender's determination that your property is located in a floodplain, you and your lender can jointly request a Letter of Determination Review from the Federal Emergency Management Agency (FEMA) within 45 days of being informed by your lender that your property is located in a floodplain.
If you have insurance before the new maps took effect, the basis for rating that policy remains unchanged (i.e., you can use the rate that was charged to you when your property was located outside the floodplain).
- I have flood insurance, and my house is in a floodplain according to the old map. The new map, however, shows my house as being outside the floodplain. Do I need to continue carrying flood insurance?
If you have federal or federally related financing for the property in question, you no longer have a federal requirement to purchase flood insurance; however, lenders retain the prerogative to require flood insurance, even for property that is not in a floodplain. If you wish to continue coverage, you may be eligible for preferred risk rates based on your property being outside the floodplain.
You should have your policy re-rated using the new map, which should lower your premium. Even if you are not required to purchase flood insurance, FEMA encourages homeowners to continue coverage at the preferred risk rates, because you may be flooded by an even greater than the 1 % annual-chance event.
