Gray Engineering vs Nature Based Solutions

Details

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.

Capital Cost

None

Operations & Maintenance

Moderate – contingent on frequency of maintenance schedule, access, and equipment considerations

Effectiveness

High in areas where overgrowth or debris drives flood risk. Can also reduce landslide risk by minimizing surface runoff.

Flexibility

High – maintenance schedules can be adjusted as needed

Barriers to Implementation

Cost; staffing capacity and access

Equity

Ensure that downstream impacts of culvert maintenance are considered, and that maintenance activities are prioritized based on greatest need
