A view from below showing the new concrete retaining walls in the middle of the new, more conventional 'shoring and lagging' (steel beam and wood board) retaining walls.
The concrete retaining walls from up on the house site, prior to backfilling and compacting the hill in behind the walls.
Another shot of the concrete retaining walls with the black steel of the new 'shoring and lagging' retaining walls next to the rusted out existing retaining wall.
Spraying water to keep the dust down during the compaction process.
The intersection of the new retaining wall (black steel at the top of the image) and the old retaining wall (just peeking out of the dirt). Also seen are the drainage piping that pulls water off of the top finish grade at each retaining wall, and also at the base of each wall through a perforated drain pipe set in gravel.
Three of the four retaining walls mostly done. The forth - a CMU wall that finishes out with the building pad elevation of each of the three lots - is up next.
