CWPP Topanga Arundo Removal Project

NOE - Notice of Exemption
Document Description
This project comprises the restoration of a heavily impacted reach of Lower Topanga Creek via removal of approximately 5 acres of invasive giant reed (Arundo donax) from the lower Topanga Creek watershed followed by re-establishment of native vegetation, including five years of follow-up treatment to ensure complete eradication of the invasive arundo in the area. Work will be completed via hand crews wielding hand tools, as well as the use of herbicide in areas where hand removal is not safe or possible. No heavy equipment will be used. Work will be conducted outside of nesting bird season and will occur prior to or avoid rain events. Follow-up treatments following the same methodology will continue biannually for five years. Willow stakes and planting of native plants mimicking the surrounding native mosaic will be employed in cleared areas to expedite re-establishment of native plants. Further information regarding the project, as well as measures to be implemented to avoid impacts, may be obtained by contacting the Environmental Coordinator listed below.
