Raleigh, NC Sets Minimum Soil Volume for Street Trees

As of this summer, Raleigh, NC now requires a minimum of 600 cubic feet of soil for all street trees planted in the right of way for new developments. Their new Street Design Manual outlines this requirement, and the design methods available for achieving it, in section 6.18, page 82-86.

The design standards also specify that soil volumes should be connected wherever possible to increase the overall amount that is available to the roots.
