Document Description
The California Department of Fish and Wildlife has executed Streambed Alternation Agreement No. EPIMS-LAN-34792-R5, pursuant to Section 1602 of the Fish and Game Code to the California Department of Parks and Recreation.
The project is limited to removal of Arundo (Arundo donax), follow up treatments of Arundo, and planting/seeding of native plants. Removal of Arundo will occur over an approximate 20-acre area within Topanga State Park. Arundo will be cleared using hand tools. Following cutting, hand tools will be used to remove rhizomes to the fullest extent possible. Cut and/or dug Arundo will be removed from the project area and disposed of off site. Areas that that are topographically restrictive and do not allow for rhizome removal will be treated with herbicide via the cut and paint method. Follow-up treatment will be conducted over 5 years.
After removal, crews will plant willow stakes, sycamore trees, mulefat, and native understory plants consistent with the surrounding community. These plantings will be supported through hand-watering on a tapered regime. No digging or planting will take place within ordinary high-water mark of the stream channel. No in-water work will occur. Aluminum foot bridges may be employed as needed to cross the channel. Project area will be stabilized as needed using silt fencing, coconut rolls, and/or sandbags to prevent soil erosion.
