In case of roads, that means in some places the roads, after two new surfaces, are at same level as sidewalk. You can still see the two new surface levels at what used to be the curb/kerb, but is now just a gap between sidewalk and road.

But those on ground floor, who cannot raise their floor level because there is a ceiling, have to install walls to prevent water from sidewalk/road now being higher than their floor level from flowing into their house.
