If a piece of land has not been mapped for soils, how should a builder indicate the soils on the site development plan?
In unmapped areas or for parcels where soil types cannot be definitively extrapolated from adjacent mapped parcels, the builder must have a soil scientist visit the site to map the soils on the property before building can commence. The Permit Office, 703-324-1555, TTY 711, on the second floor of the Herrity Building has a list of certified soil scientists for hire. A 2001 Letter to Industry (pdf) explains when geotechnical reports are required for submission.
