Steeper slope angles mean less land take, reduced earthworks volumes, reduced embodied carbon, and cost savings. However, they may also come with increased future maintenance. Considering long-term slope conditions in design enables decisions about whole-life cost and carbon trade-offs between initial slope angles, asset-life, and future maintenance.
