Re: Driveway surcharge on retaining wall

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I would stick with the 2' surcharge.  Considering the load that occurs when a fire/rescue truck pulls up into the driveway, there is no real reason to reduce the load.  And for an "L" shaped retaining wall, the footing gets large quickly.

I am looking at a short, 4 ft to 5 ft retaining wall that is on a property line.  The property line is on the heel side of the wall, therefore there is no heel at the footing.  Also, there will be a driveway on the heel side of the wall in the future.  If I put a 2 ft (highway) surcharge on the heel side of the wall the footing at the will seems to excessively large.  Since the driveway will be to a residence I think the 2 ft of surcharge is excessive, but there may be some short term construction loads that will be larger than passenger vehicles.  I think that a 1 ft surcharge would be fine for the life of the structure.  Anybody out there disagree with using a 1 ft. surcharge?
