CCAT is in a pressing need to secure a portion of the hill from landslides North-East of the house. There is already a small concrete retaining wall close to the building but it is clearly not sufficient considering the slope and composition of the soil. With the kind of rainfall we are having, soil erosion or small landslides are a treat to some Redwood trees over that hill. In collaboration with Eghan working on rammed earth blocks, I am going to stabilize that slope by reshaping, planting vegetation and/or building a retaining wall with old car tires or another appropriate materials.

Background
Moving the CCAT building to a new location has caused new problems related the topography of this new spot. A concrete retaining wall was supposed to be built but it never happened. So CCAT members decided to take the matter into their own hands by trying to resolve the problem using appropriate technologies.
Description of Opportunity
CCAT is in a pressing need to secure a portion of the hill from landslides North-East of the house. There is already a small concrete retaining wall close to the building but it is clearly not sufficient considering the slope and composition of the soil. With the kind of rainfall we are having, soil erosion or small landslides are a treat to some Redwood trees over that hill. In collaboration with Eghan working on rammed earth blocks, I am going to stabilize that slope by reshaping, planting vegetation and/or building a retaining wall with old car tires or another appropriate materials. This work should be done in a timely fashion since it is important to have a secure environment where we feel safe.
Criteria
The criteria used in a future decision matrix are the following (in no particular order):
- cost
- efficiency of construction
- ease of maintenance
- durability
- use of natural materials
- aesthetics
- multi-usage
- security
- ease of deconstruction.
