Clear vegetation and debris from drainage systems and clear drains more frequently to prevent clogging and flooding, especially before major storms. Determine appropriate maintenance schedule based on site-specific considerations.
Moderate – contingent on frequency of maintenance schedule, access, and equipment considerations
High in areas where overgrowth or debris drives flood risk. Can also reduce landslide risk by minimizing surface runoff.
High – maintenance schedules can be adjusted as needed
Cost; staffing capacity and access
Ensure that downstream impacts of culvert maintenance are considered, and that maintenance activities are prioritized based on greatest need.
