San Francisco Tree Maintenance
Requests April 2015

This map informs me that the most tree maintenance cases come from a very central part of the city. After exploring more with interactivity, I have come to the conclusion that this "hotspot" is at the intersection of Market and Mission, which happens to also be at the intersection of four supervisor districts. This "hot" area is one of the more violent sectors in the city and you can tell this from the 311 Tree Maintenance data of April 2015.
