At Phase I development of the Canyon Ranch Residences, Blocks 8 and 14 were left undeveloped due to their existing site conditions. These blocks were along the property line and the slope adjacent to them was very steep. Residential buildings, a chapel, and a commercial building were to be constructed in the area. To protect the blocks, an 11 meter-high retaining wall was required to be constructed at the steep slope. The wall aimed to maximize the area of the property such that an additional flat land on top of the wall must be achieved.
