Your link isn’t working for me but the IPCC middle of the road scenario has 10in by 2100 and past IPCC middle of the road estimates from the 90s have so far turned out to be reasonably accurate predictions.
After digging into it a bit to find a better source for you, it turns out that my number was wrong anyway. Turns out the sea level rise for the contiguous US is expected to be quite a bit higher than the global average. I had no idea!
That said, I don't think they assume our emissions trend from the last 50 years will continue unabated.
1ft at 2075 assumes we curb emissions somewhat:
