To answer your questions, you can:
1) talk to the homeowner and ask what’s going on; just a conversation, not an accusation. Start by introducing yourself, and say that has been sitting there for awhile and you were curious about how long it will be there
2) call the number on the porta potty and ask them what’s going on and how long do they expect it to be there
3) call your district supervisor (
Village Community Development Districts) and discuss with him/her
Up to you as the action you wish to take.
P.S. if you talk to this homeowner the way you talked to graciegirl, I don’t think you’ll get a satisfactory outcome.
