It creates a splash pool after it rains, but in reality it is indeed a trip hazardI think this park looks great from above.... but on ground level, not so much.... the trees will help once they're grown in, but the REALLY strange part.... is that theres all of these bumps-1"differences in height between stones, such a tripping hazard! I dont see how they were allowed to create such things.... or what the motivation was behind it!
