Preface 
This document is one of a series of summaries for the U.S. Environmental Protection 
Agency (EPA), National Coastal Assessment West Coast regional component (NCA- 
West). The NCA is the coastal component of the nationwide Environmental Monitoring 
and Assessment Program (EMAP). This document is a summary of a pilot assessment 
of the condition of estuarine intertidal, soft bottom habitat of the states of Washington, 
Oregon and California. The NCA in the West Coast region is a collaborative effort 
between EPA and the states of Hawaii, Alaska, California, Oregon and Washington, the 
territories of Guam and American Samoa, and the National Oceanic and Atmospheric 
Administration (NOAA). The program is administered through the EPA and 
implemented through partnerships with a combination of federal and state agencies, 
universities and the private sector. The West Coast Estuarine Intertidal Assessment 
involved the participation and collaboration of EPA, Washington Dept, of Ecology, 
Oregon Dept, of Environmental Quality, and the Southern California Coastal Water 
Research Project (SCCWRP), with additional contributions from personnel of Moss 
Landing Marine Laboratories and the San Francisco Estuary Institute.
