Large woody debris (fallen trees, logs, and branches) can be placed in streams to reduce the flow of water and help connect the stream channel to its floodplain, reducing flooding. Work with relevant agencies and landowners to determine feasibility to implement measure.
Low/Moderate – dependent on equipment costs and expertise required
Moderate – will require monitoring/maintenance to ensure woody debris is correctly placed
Moderate/High – can significantly reduce flooding by connecting the stream to the floodplain
High – debris can be moved as needed
Permitting; design/construction knowledge; maintenance approaches/expertise
Ensure that techniques do not exacerbate flood risk to equity areas/downstream communities, and/or mitigate associated downstream impacts.
