flooding has been reduced here they spent a lot on road widening but also put in new main drainage much bigger than the previous, this all the way down the main highway which used to flood regular and it would wash down the hill any parked motor bikes, still get some water above the drain level when its realy bad storm, but its a big big improvement, bennefits ,, after the rain its cool the air is fresh and any trash dog poops ect is washed away
