If you live somewhat close to the river in North Albany, OR, have a look on the new FEMA flood maps SOON! While some of the locations and identifications are being disputed, chances are your property is now in a flood plain, making flood insurance mandatory in case you have a mortgage.
If you so far did not have flood insurance but the maps are placing you in the 100yr flood plain and you are not purchasing flood insurance as requested by your bank, the bank will have to do it for you, most likely not the less expensive alternative....
If you are not (yet) in a flood plain, purchasing flood insurance is rather inexpensive and you might be able to carry it at a low rate in the future even if your property's status is changing.
