Retaining wall, Live Oak Springs ·
A limestone terrace wall on a hillside lot
A slope that washed into the driveway every storm, turned into two level terraces with stone steps between them.
- What we did
- Two-tier dry-laid limestone wall on a gravel footing, drain pipe, geogrid, stone steps
- Size
- 86 ft of wall
- Time
- 11 days
- Cost
- $24,600 all in
Every heavy rain brought half the back slope down onto the driveway. Rather than one tall wall, which would have needed a permit and an engineer, we built two walls of three and a half feet, one above the other, with a level terrace between.
Each tier sits on a foot of compacted gravel, with a drain pipe behind the first course and two layers of geogrid in the backfill. The steps between the terraces are cut from the same stone. It rained two inches the week after we finished; the driveway stayed clean.
