Along the back edge of the rear lawn will be a low wall made of these bandera granite boulders.
Bare! Earlier in the project, they took down two of the crowded douglas firs in the back. Unfortunately, the remaining tree looked awful, so it came down, too. In a few weeks, we'll have a nice arborvitae hedge started.
Before the project began, our backyard had quite a slope to it. Now, the main part of the yard is nearly level and they're building a low rock wall along the edges of the (future) lawn.
