Sanitation Districts of Los Angeles County

landfill-sanitationSanitation Districts of Los Angeles County, On Call Regional Services Contract, and On Call Puente Hills Landfill Contract, Puente Hills, CA

JMA has provided comprehensive paleontological, archaeological, and historic architectural services on various projects for the Sanitation Districts of Los Angeles County (LACSD). Our team completed three projects within the Puente Hills Landfill, Whittier, CA from 2002 to 2007. These projects included the 2002-2003 Lower Western Cut for the footprint of the Material Recovery Facility, the 2006-2007 Southeast landfill expansion project completed by the District, and a slope stabilization project on the North Nike site slope. JMA field staff identified and documented fossil localities during the course of these projects. The fossil localities included invertebrate and vertebrate specimens from the late Miocene Puente Formation. Our staff provided as-needed paleontological and archaeological mitigation monitoring services for the three projects and produced weekly, monthly, yearly, and final project reports.

In 2008 JMA was awarded a full-service contract with LACSD to provide cultural and paleontological services. From 2008-2011 JMA conducted archaeological and paleontological investigations for the District. These projects include architectural building assessments such as a Section 106 (NRHP eligibility) study for the White Point Ocean Outfall System, cultural resource monitoring for the Santa Clara River Main Relief Trunk Sewer Extension, and paleontological salvages at the Puente Hills Intermodal Rail Facility, as well as other various cultural, paleontological, and historical resource assessments.
