Both NorthShore and Block 185 meet it with different strategies. NorthShore meets the stepback by stepping back in three large blocks. Block 185 is almost a literal diagram of the height and stepback requirements. The reason Block 185 can go higher than 45 feet on the creek side is that the original property line / Rio Grande ROW is within the creek, so the bottom of the stepback slope at 45 feet is some distance from the building located on the top of the bank. When Silicon Labs and City Hall were planned, they amended the North Shore Central subdistrict of the WOD to create a new three block City Hall subdistrict. In the new subdistrict, the height and stepback requirements can be met the standard way (45'/70 degrees) or if the maximum height is 90 feet. So the Silicon Labs buildings cannot be any taller unless they redevelop with a maximum 45' height on Cesar Chavez, or amend the WOD again.

So there is some height restrictions.
