I’m leaving the city for a bit so I took these photos on my way to catch BART for the airport. I expect others will submit some later photos, and I will add them at the end of the day. In doing this daily, we’re looking for progress and patterns that might be helpful in understanding how to change the dynamic of an intersection and corridor that has long been a high-crime area.

Why, for instance, are the sidestreets on the southside — with the exception of Capp Street — on the southside generally as clean as Rondel Place pictured below?

We’re also talking to experts to see what they have to say , neighbors, and city officials . We’ll also look more carefully at the research on urban dynamics. So, stay tuned. This isn’t just a 16th Street problem but a dynamic you can find at any number of intersections.

Accountability figured large in Mayor Daniel Lurie’s campaign for mayor and he seems anxious to have voters hold him to his word. (This week, he promised residents thing would change, and acknowledged that conditions were still “unacceptable.”)
