I am designing a retaining wall that is adjacent to a sidewalk (as the subject line implies). Would a 12' wide, 3" thick concrete sidewalk provide lateral resistance to prevent sliding? If so, is there any building code that references how this would be accounted for in calculations?

Thanks.
 
No. What if the sidewalk is removed? There goes your sliding resistance (even if a 3" sidewalk could provide enough passive pressure).

Google City of Memphis Civil Standards, take a look at items 9 & 10 on the list
