The project is limited to securing the existing retaining wall built of wood on the Permittee's property along Morrison Creek. In order to secure the retaining wall, native/local dirt shall be used to fill and compact behind the wooden support structure. The fill dirt shall be compacted to prevent fine sediments downstream when water is flowing in the creek. Any exposed soil shall be covered with native vegetation (e.g. willows or native grasses) to increase soil stability. All other non-native materials shall be removed from the watercourse.
