Trees protect water and soil resources by reducing the amount of runoff and pollutant loading through evapotranspiration, interception and infiltration.  A healthy urban tree canopy also provides the added benefit of shade and lower urban heat indices.  New planter box design technologies are allowing for increased soil volumes under pavement allowing for larger, healthy trees and the treatment of stormwater.
