(November 2011-2013) Paleo Solutions was hired by AECOM to perform all paleontological and archaeological monitoring for the Colton Project located in the City of Colton, San Bernardino County, California. UPPR and Caltrans District 8 are the owners of this project. Numerous archaeological sites have been protected by Environmentally Sensitive Areas (ESAs) near and within the limits of construction. In addition, several members of our staff successfully completed UPRR extensive safety training and background checks. Both paleontological and archaeological monitoring have been completed.
