Per the SOA, the Gypsy Hill Trail Rockery Wall Repairs are now completed, except for landscaping the tiers. Photos, from top to bottom, depict: 1) Shotcrete installation, 2) Wall anchor locations, 3) Completed wall with decorative overlay (not too bad looking by itself) and 4) Repaired wall compared to original wall (what do you think?)

Hopefully the contrast between the repair section and the original wall can be reduced with some landscaping. This repair approach was estimated to be about $1 M less than replacing the rock wall with a new wall similar to the original.
