The city of Santa Monica created a better solution - easy access to public toilets with an interior that is completely metal so its easy to hose down to keep them clean. For the most part they keep these very clean so while you see these outbreaks downtown you don't see them in Santa Monica because they do have public bathrooms. In downtown LA its impossible to find a public bathroom often the metro stations don't even have bathrooms. The assumption made is that bathrooms attract the homeless but in reality creates a situation where no one can wash their hands easily downtown.
