Site Survey & Assessment in Permaculture Design
The Permaculutre Site Survey allows the Permaculturist to gather data as related directly to site observations. In Permaculture Design we break the Site Survey into ten (10) distinct observation areas as follows:
1. General Information
2. Site Information Collation
3. Landform & Orientation
5. Access, Utilities, Rights-of-way
6. Biological Systems
9. Natural Disasters / Catastrophe
10. Other Areas of Observations
