Those wetlands keep the rain from flowing straight out into the ocean; part of the reason we're in this mess now is that we've spent the last 100 years plowing them into the ground and pouring concrete over them (see: LA river).
The general tendency to cover the ground with concrete is more than half of the problem of LA, they receive more than enough rainfall every year to cover 100% of their needs but more than 99% of it runs off because that's what they designed the city to do. It's not just wetlands, it's all the lands.
