Before the first course of blocks could be laid, we needed a gravel base in the ditch. We filled it a couple of inches and
then tamped it using a gas-powered plate compactor. This became an iterative process as we tried to get the base level across
the yard. In the last set of pictures, you can see where Mike placed conduits that will run under the wall. These conduits will
carry electrical power to the wall lights. (which means they also give a good idea of how high the wall will be)
Here is a picture of Mike building a ramp, so we can easily roll things from the garage to the patio.
