San Diego is famous for its pristine beaches, but a hidden pipeline of pollution threatens the coastline every day. The San Diego Regional Water Quality Control Board estimates that county storm drains carry approximately 30 million pounds of trash to the ocean each year. Much of that trash starts its journey in inland neighborhoods: the same streets, parks, and sidewalks where we live and work.
How Litter Travels
When trash is dropped or blown onto city streets, it eventually washes into storm drains during rain events. Unlike sewage, which goes to treatment plants, stormwater flows directly to creeks, rivers, and the ocean without any filtering. A cigarette butt dropped in North Park or a plastic bag tossed in City Heights can end up at Mission Beach within hours during a rainstorm.
What We Find Most Often
Ocean Conservancy's International Coastal Cleanup Report consistently identifies cigarette butts as the most commonly collected item, accounting for over 2 million items annually worldwide. In our San Diego cleanups, the top items we encounter are:
Most common litter items in San Diego neighborhoods:
- 1.Cigarette butts and vape cartridges
- 2.Food wrappers and fast-food packaging
- 3.Plastic bottles and bottle caps
- 4.Plastic bags and film packaging
- 5.Aluminum cans and glass bottles
The Inland Solution
While beach cleanups get the most attention, the most impactful intervention happens upstream, in the neighborhoods where trash originates. By cleaning up inland areas regularly, we intercept litter before it reaches waterways. Keep America Beautiful research shows that neighborhoods with regular cleanup events see up to a 60% reduction in litter within one year.
That's why LocalCleanup focuses on neighborhood-level cleanups across San Diego. We're currently active in 17 neighborhoods, from North Park to Pacific Beach to Carmel Valley. Every piece of litter we pick up inland is one less piece that reaches the ocean.
