Kari Paulson

Hydrologist, Geomorphologist

During her fifteen years in the natural resources field, Ms. Paulson has focused her work on issues of hydrology and landscape processes, with particular emphasis on evaluating land use impacts on watershed processes in small and large-scale watersheds and the design and implementation of watershed restoration projects as they relate to salmonid habitat. She has worked closely with policy makers and scientists from all levels of government (city, county, state and federal), as well as those working with industry (logging, mining and power companies), Indian tribes and environmental groups. An example of this work includes her role as the lead geomorphologist on an interdisciplinary team of scientists who completed an Environmental Impact Statement for the Washington Department of Natural Resources that evaluated how proposed changes in forest practice rules might affect channel stability and fisheries habitat. Ms. Paulson is a licensed engineering geologist in the state of Washington, received her BA in geology from Carleton College and a MS in forest hydrology at the University of Washington.

 

Peter Sabee

President/CEO

Mr. Sabee has worked as an environmental scientist since 1985. His principle areas of expertise include environmental assessments, wetland science, baseline environmental studies and management of technical projects involving regulatory compliance. He has managed all aspects of contaminated site investigations and response actions and has conducted Phase I and II assessments throughout the United States.
