Once you raise the crossing to the curb level you now need to implement storm drainage beside the hump to avoid any pooling of water. A simple speed hump is probably a few thousand dollars, once you need to dig up the road to redo drainage you are probably in the hundreds of thousands to millions of dollars.
It sucks but theres always a cost/benefit analysis going on with these things.
This speed hump does look like it has had the drainage redone below grade to ensure a slightly smoother crossing.
Yes, this is all true, but the cost. It's on the order of tens of thousands for doing a proper raised crossing with drainage (and that's considering that the city seems to feel it cannot use the even cheaper options used elsewhere, where the curb is kept open by bridging with a metal plate instead of installing new storm drains.
