Or. Admin. R. 603-072-0010 - Definitions

As used in OAR 603-072-0005 to 603-072-0025:

(1) "Stream Corridor" means a perennial stream and its associated natural fringe and trees, which includes the area occupied by normal high water, the area in which the stream meanders, or in recent decades has meandered, and the immediately adjacent areas which support a belt of higher-growing vegetation needed to shade the water and protect the banks from excessive erosion, but does not include the whole of a valley floodplain.
(2) "Streambank Erosion" means the wearing away of the whole side of a streambank from the stream surface down to the foot of the streambank in the stream bottom, which wearing away is the result of the scouring action of moving water, which is a rate greater than a rate resulting in imperceptible change, and which is a threat to life, property or water quality.
