Leslie F. Harder, Ph.D., P.E., G.E.
Senior Water Resources Technical Advisor
Dr. Harder is a Senior Water Resources Technical Advisor in the Folsom office. His primary duties are to manage and provide technical support for the planning and design of water resources and environmental restoration related projects. These projects include conducting hydrology and hydraulic analyses, conducting flood hazard assessments, formulating flood damage reduction plans, conducting reconnaissance and feasibility level planning studies, and preparing final designs and construction documents.  His responsibilities also include business development, scoping new work and preparing proposals, scheduling work with subordinates, providing training and reviewing work.

Dr. Harder has also worked on several projects with the United States Army Corps of Engineers involving levee designs and design criteria, and has been involved in several post-earthquake reconnaissance studies of the performance of earth structures.  Recently, Dr. Harder was part of the National Science Foundation team that studied the performance of levees in the New Orleans area following Hurricane Katrina.  In 2008, he was appointed by the Assistant Secretary of the Army to serve on the National Committee on Levee Safety, a committee mandated by the United States Congress to develop and recommend a new national levee safety program.  Dr. Harder also serves as the Chair of the Board of Senior Consultants for the Natomas Levee Improvement Program.
