Sure, it is good to see people digging on the site. But it is even better to see them finally building. What they are doing here is forming the foundation for the first retaining wall at the bottom of the slope. Slowly they will work their way up the slope, filling in behind finished retaining walls and building more retaining walls higher on the slope.
This is wall that they will eventually build, then face with rock. These are interlocking concrete segments that will be linked together for strength. By next week I hope to be able to show you at least a partial wall.
