Consider removing and replacing the earth with reinforcing geofabric and soil, making an MSE wall, (no active pressure)
Remove the soil and replace it with EPS Geofoam (Styrofoam blocks) www.afpcontrol.com and provide a drive surface on that, with the stacked stone remaining in place. Again no active pressure
Remove the soil and back fill with slurry or soil cement that locks into the bed rock. Also no active pressure if stable
Lots of details and considerations in all the alternatives.
How about a load test for the city and ignore what the soils engineer calculates. You said this is an old road, what would the city accept as an existing condition?
Just my thoughts.
I have a client who is
purchasing two lots for two custom homes in the foothills of a mountain
overlooking a golf course in Palm Springs. There is an old road about 300 feet
long that makes the climb to the property; one side of the road is a rock hillside
cut for the road years ago. The other side that is seen from below is simply
stacked stone slabs retaining soil. The maximum height of the unsupported
roadway (or that which is supported by the gravity wall of stacked stone slabs)
was determined by the geotechnical engineer to be insufficient for heavy
utility vehicles such as a fire truck that must be allowed access to the lots
