Check the construction site. There should be signs with safety regs, the agency behind it and contractor information. Hope it helps. And if there isn't, try either Houston Parks or Harris County Flood Control District.
There is a rule. One cannot get within 6 feet without tie off on a roof top. This may apply here but the authority or management may have the final say so if the shoring can hold the load without bulkhead. If you see a truck slowly sink in as the shore gives out, now you know why. The professionals know what they are doing.
