Dredging and Dredged
Material Disposal Use and Activity
Dredging and dredged material disposal
can only be allowed in selected zoning designations (Oregon)

Only those development uses and activities

the site's future use for dredged material disposal are allowed,
subject to the policies and procedural requirements of the underlying
zone.
Types of dredging and dredged material

the zone or shoreline management designation in which the uses
