Landform/Geomorphic Grading for Sustainable Hillside Developments

Schor, H. J. / Gray, D. H.

Landform/geomorphic grading or "Landforming" attempts to mimic not only slopes but entire landform shapes and vegetation patterns that have long-term, self sustaining properties. Landform graded slopes for example are characterized by a continuous series of distinctive curvilinear forms with varying slope gradients. This grading approach results in slopes that are attractive, cost effective, and environmentally compatible. Slopes constructed in this manner not only blend in with their surroundings but are also superior in the long run in terms of resistance to surficial erosion and mass wasting. Landform grading has been used successfully in recent years in hillside developments, watershed restoration, mine reclamation, and mass-grading operations. Two hillside residential projects in Southern California are described in this paper where landform grading was utilized, namely the Anaheim Hills and Talega Planned Community developments. Both developments had to confront difficult topographic, geological, and regulatory challenges. The Land-forming approach resulted in a more natural looking topography and featured an alternative landscaping and re-vegetation plan.
