INSTRUCTORS: Linda A. Potter, PE, CFM, is a Project Director for Atkins North America, Inc. with extensive experience in post-burn watershed assessments. Her post-burn work includes the Southern California 2007 Firestorm, the Yarnell Hill Fire in Arizona, the Goodwin fire in Arizona, and the recent Thomas Fire in Santa Barbara and Ventura Counties. Linda specializes in arid region hydrology and hydraulics, and has completed over 3,000 miles of floodplain delineations in the past 10 years. She has 25 years of civil engineering experience including work as a contract floodplain administrator and engineer for a rural county in Arizona. She has served on the Board of the Arizona Floodplain Management Association since 2007. In addition to technical analyses, assisting communities with outreach and communication is one of Linda’s passions.

Iwan Thomas, PE, MS is a Senior Engineer for Atkins North America, Inc. with experience in recent post-burn watershed assessment including the Thomas Fire in Santa Barbara and Ventura Counties and the post-fire hydrology for various fires in Lake County, California. He has over 15 years’ experience providing assistance in a wide range of hydrologic and engineering capacities. Iwan was the project manager and technical lead for the California Department of Water Resources Alluvial Fan Floodplain Evaluation and Delineation Program from development of methodology to implementation and flood hazard delineation on alluvial fans throughout California. Iwan previously taught the FMA course on geomorphology and alluvial fans.
