Gray Engineering vs Nature Based Solutions

Details

Modify the slope gradient by redistributing soil or rock mass or creating flat or gently sloping areas on steep slopes to minimize landslide potential.

Capital Cost

Moderate/High

Operations & Maintenance

Low

Effectiveness

Moderate – modifying the slope’s geometry can help reduce landslide risk

Flexibility

Moderate – although slopes can be re-modified in the future, repeated alteration of the slope may decrease slope stability and create cascading impacts in other areas

Barriers to Implementation

Cost; limited space/options for slope modification; resistance from neighboring property owners

Equity

Ensure equitable siting of infrastructure across a range of equity areas, based on greatest need
