We all go that there are a number of reasons that street trees are good, and almost a necessary for pedestrian based commercial area... But as with many things, can we prove it with data and studies? I need to find a reason to rock the boat and get a redesign of the road and street scape, including the installation of street trees along our historic downtown. Right now, there are no trees. I don't want to just say they can do some things, but I want data to back it, expecially when it comes to the economic benefit to both the City and business owners.
