Toppers empty lot with nothing happening yet is next to El Zafiro

The "construction" next to Karakters is actually where a concrete foundation USED to be, but it appears they are starting something up again. That foundation was there for years and came/went with sand and storm surges. It is where people park for Karakters, between them and Mary's Boon.
Several years ago fishermen used to stand next to that foundation/wall and Karakters would cook them up what they caught.
