Sidewalk constructed against Miami curb

EngWannabe7 · Mar 4, 2021

I am in a debate regarding whether a sidewalk can be constructed against a Miami curb in Florida. The FDOT specs 522-001 only shows a sidewalk mounting to a Type F curb but does not specify if it can or cannot be constructed against a Miami curb. Is a sidewalk able to be constructed against a Miami curb and if so what alterations, if any, need to be made to the sidewalk? Thanks in advance for your insight.

There's no problem with casting a sidewalk against a mountable (Miami) curb. Since the height of the mountable curb on the back side is lower than a barrier curb (Type F in Florida), the subgrade for the sidewalk will require more excavation to get the slab thickness.

Thank you both. I greatly appreciate your insight. I was concerned with the Miami curb being confused for a ramp since the slope is well over the 8.3%. It was pointed out to me that this falls more under pedestrian drop off, to which it complies, and not ADA requirements. ADA compliance on the Miami curb is only an issue at the ADA ramps. Thanks again for your insight.
