Neil M. Jordan, P.E., D.WRE

Mr. Jordan is a registered civil engineer with 22 years of public agency and private practice flood control experience specializing in 1-D and 2-D hydrological and hydraulic analysis and modeling. Mr. Jordan’s civil engineering experience includes hydraulic and structural design of urban flood control structures, Federal Emergency Management Agency (FEMA) floodplain studies, and National Pollution Discharge Elimination Program (stormwater quality and best management practices). Mr. Jordan’s professional engineering career is preceded by 10 years of varied ionizing radiation protection and teaching experience as a civilian health physicist for the Department of the Navy (shore activities), and 2 years as a civilian health physicist and instructor at a Navy shipyard. His regulatory agency experience includes interactions with FEMA, the Environmental Protection Agency, the Army Corps of Engineers, the Nuclear Regulatory Commission, the Department of Energy, the Department of Defense, and various state and local agencies. Prior to joining Exponent, Mr. Jordan held several senior-level engineering positions for the Orange County Flood Control District.
