Steep Slope Geotechnical Requirements

To protect against slope instability for new development, Delta has striven to accomplish a comprehensive policy for development in steep slope areas of Delta. It applies to all development in areas of Delta on or near steep slope such as the many ravines or bluffs common in North Delta and Tsawwassen.

A combination of detailed geotechnical engineering reports, attention to the preservation of existing vegetation, specific slope instability performance measures, a variety of measures to share knowledge about the slopes, encouraging accountability and supplementary geotechnical peer reviews are presented to guide the development community.
