Can a Retaining Wall Be Built Next to a Driveway?
Yes, a retaining wall can be built next to a driveway, but the wall must be planned for the driveway's location and use. Cars and trucks create live loads above the wall, while the pavement changes how water runs across and into the surrounding soil.
There is no universal setback that works for every property.

Vehicle loads can affect the wall
A driveway close to the top of a retaining wall can add pressure to the retained soil. The effect depends on the wall height, distance from the wall, vehicle type, soil and reinforcement. The CMHA design manual treats vehicle traffic as a surcharge load that may need to be included in the wall design.
Drainage and driveway edges matter too
The plan should keep runoff from concentrating behind the wall, protect the driveway edge and leave enough room for excavation, base preparation and compaction. The driveway and wall should be evaluated as one site condition rather than two unrelated projects.
