Lower the land along the Misso northern edge

Misso is 95% water and owned completely by the Lindens. There is an island which is no problem. But along the northern edge of Misso the land is raised up a few meters above the water level. Could we get that lowered to be below water level? It serves no purpose and would allow boat traffic to pass, esp in the NE corner.

The NE corner was about the only part I could correct without affecting the way another resident had built. Hopefully this will suffice! Thanks for letting us know.
