CR-15 If human remains are encountered, California Health and Safety Code Section 7050.5 states that no further
disturbance shall occur until the Riverside County
Coroner has made the necessary findings as to origin.
Further, pursuant to California Public Resources Code
Section 5097.98(b) remains shall be left in place and
free from disturbance until a final decision as to the
treatment and disposition has been made. If the
Riverside County Coroner determines the remains to
be Native American, the Native American Heritage
Commission must be contacted within 24 hours. The
Native American Heritage Commission must then
immediately identify the “most likely descendant(s)”
of receiving notification of discovery. The most likely descendant(s) shall then make recommendations
within 48 hours and engage in consultations
concerning the treatment of the remains as provided
