I would fight if it's still up for consideration. Go around to all your neighbors and let them know. Talk to the people in charge and let them know you're going to fight this until the end. Tell them you'll sue if they continue with their plan.
If all else fails and they do make it a homeless shelter make it a very inhospitable one. Put up signs saying this is a snitch neighborhood. Continously call the cops on suspicious people. Let the people who are making these decisions know that you'll be doing this.
Also, let the people in charge know that you'll plaster their name all over the internet if they allow this to happen. Show no mercy
