That's an excellent and practical question for any business owner or property manager. For a typical one-block commercial area, I'd generally recommend starting with 4 to 6 well-placed outdoor trash cans. However, the "right" number isn't one-size-fits-all; it depends heavily on several key factors.
Think of your block's unique profile. Foot traffic is king. A block with a popular coffee shop, lunch spots, and high pedestrian flow will need more bins than one with mostly office buildings. Benchmarks and gathering points are prime locations—near bus stops, seating areas, or outside a busy convenience store. A good rule of thumb is to aim for a bin to be within sight from any point on the sidewalk, preventing litter from "walking" too far.
Placement is just as crucial as quantity. Ensure bins are at key pedestrian decision points: near crosswalks, building entrances, and next to parking meters. They should be paired with recycling receptacles where possible. The goal is to make disposal the easiest option.
Ultimately, start with 4-6 bins, monitor them for overflow (especially on weekends), and be ready to adjust. Well-managed waste directly impacts the cleanliness, safety, and overall appeal of your commercial area, making it better for everyone.
