The coastal levee is the result of the accumulation of sediments of the Parana River on the shore; it is low rise, not higher than the 3 meter canyon, and is bounded on the east by the river and on the west by residual lagoons from former water channels. Its width does not exceed 250 meters, while the built portion covers about 600 meters long. Some fields are cultivated in the low semi-permanent floodplains.
