When planning waste management for a small city plaza, I'd recommend starting with 4-6 well-placed outdoor trash bins as a general guideline. The exact number depends on several practical factors that determine your specific needs.
First, consider your plaza's size and typical foot traffic. A compact plaza receiving moderate visitors might manage perfectly with four strategically positioned bins, while a more popular gathering spot could require six or more. Look for high-activity zones like seating areas, food vendor locations, and main walkways where people naturally congregate.
Placement matters just as much as quantity. Position bins at regular intervals – nobody should have to walk more than 30 feet to dispose of litter. Install them near benches, entrance points, and food concession areas where waste generation is highest. Make sure they're visible but not obstructive to foot traffic flow.
Don't forget about recycling stations! Many modern plazas now include combination units with separate compartments for trash and recyclables. These comprehensive stations can sometimes serve double duty, potentially reducing the total number of individual bins needed.
Maintenance capacity is crucial – even the perfect number of bins becomes ineffective if not emptied regularly. Coordinate with your city's sanitation schedule to prevent overflow, especially before and after weekend events or farmers' markets. Consider durable, vandal-resistant designs that contain odors and discourage pests.
Ultimately, observe your plaza's usage patterns for a week. Notice where litter accumulates and adjust your bin placement accordingly. The right number is what keeps your space clean while fitting seamlessly into the plaza's design and maintenance capabilities.
