Missions appearing in the middle of the river/bay

Missions that shouldn't be on the river or water are appearing. For example, I am getting garden shed fire and motorcycle accident on the river. (For your reference my base is in New York City) Please fix this so that only accidents related to water will appear on the river/sea.

I don't know if this is possible or not, but maybe the dev could create a boundary along the edge of the waters so land missions will not spawn inside them.
