There is growing understanding that a natural bulwark against climate change is mature trees.  Please do not make it easier for actors like VDOT to put at risk a key ally in reducing impacts of severe weather! Trees provide enormous public benefits--reducing flooding, improving air quality, enhancing public health, and reducing energy use, to name a few. Any regulation that impacts healthy trees requires in-depth cost-benefit analysis; please ensure that analysis is done. Until then, these regs should not be fast-tracked. Thank you for taking into consideration the ecosystem benefits of trees and all they do for residents.
