Document Description
In 1996, Gladstone Way residences experienced property damage from flooding events associated with Coleman Creek. The purpose of the proposed project is to clear vegetation that may be obstructing appropriate storm flow passage within Coleman Creek, and to support habitat restoration efforts within the riparian corridor. The work would involve thinning and trimming densely overgrown native willow and non-native Himalayan blackberry along a 100 foot section of the Coleman Creek stream channel while maintaining existing shade canopy (Project Site 1), and trimming non-native Himalayan blackberry along additional segments totaling 150 linear feet (Project Sites 2 and 3). Selective thinning techniques would be used in limbing up mature trees, removing down-ward growing branches and dead vegetation debris to create a “tunnel effect” for storm flow passage. Himalayan blackberry canes would be cut at just above ground level and removed from the stream channel. Best management practices would be employed to ensure that there are no impacts resulting in soil disturbance or tree mortality.

Type, Section or Code
Pursuant to Section 15304 (Minor Alternations to Land)
