Build proper shelters for homeless people and animals, get them some proper healthcare and education/skill training so that they wouldn't be on the sidewalks constantly suffering. Charge idiotic drivers hefty fines for driving like jackasses and putting everyone's life in danger. Charge those idiots who dump their garbage on the sidewalk without disposing of it properly some hefty fines. All Flat Earthers would be executed on sight and I'd have a signs up around the town that said "Flat Earthers are an invasive species, shoot on sight if there's evidence that you've encountered one. Let's make them extinct like the dinosaurs..."
