Please note that the interactive D.C. soil map on GCAAR's website is temporarily disabled. We are
currently working with D.C. government officials to remedy the situation. In the meantime, please
use the Library of Congress, which has a high-definition map of the 11 soil types that
must be included in contract addendums. If you have any questions, please contact Evan
Loukadakis at firstname.lastname@example.org.
