DOUGLAS C. BEYERLEIN,

Mill Creek, WA
Water Resources Planning
Mr. Beyerlein has over 30 years of experience in numerous aspects of water resources planning, flood studies, and stormwater management.
Before co-founding Clear Creek Solutions Mr. Beyerlein worked for Hydrocomp and Anderson-Nichols in the San Francisco Bay Area and later Snohomish County Surface Water Management and AQUA TERRA Consultants in Everett, Washington.
As senior hydrologic engineer and engineering group supervisor for Snohomish County, Mr. Beyerlein helped to develop the surface water management program for the county. His responsibilities included watershed planning, streamflow and water quality monitoring, lake management, public education, flood control planning, development of county drainage code, and compliance with state and federal water quality laws.
He has experience with EPA's HSPF, the Army Corps of Engineers' HEC-1, HEC-2, HEC-5, and HEC-RAS models, and FEQ. Mr. Beyerlein has led the engineering community in the development of new, more accurate tools to analyze the impacts of land development on streams and fish habitat. As a result of his leadership, in 1999 his firm was awarded a contract by the Washington State Department of Ecology to develop the Western Washington Hydrology Model (WWHM) to accurately measure land development impacts and size stormwater facilities accordingly.
Mr. Beyerlein teaches workshops on the theory and application of HSPF. His clients have included the U.S. Bureau of Reclamation, U.S. Natural Resources Conservation Service, Washington State Department of Ecology, King County, Snohomish County, Thurston County, Clark County, City of Kent, CH2M Hill, OTAK, Ebasco Environmental, David Evans and Associates, EMCON Northwest, Alpha Engineering, and KCM.
He has written and presented landmark stormwater papers including “Why Standard Stormwater Mitigation Doesn’t Work” and “Effective Impervious Area: The Real Enemy”.
Mr. Beyerlein is licensed as a Registered Professional Engineer in Washington and California and is certified as a Professional Hydrologist by the American Institute of Hydrology. He is also a member of the American Water Resources Association and the American Geophysical Union.
In his spare time he runs marathons and is a freelance writer for local publications such as Northwest Runner and Washington Trails magazine. He and his wife Joan are often found trail running with their dogs in the Cascades.
