1. Clear Creek Solutions, Inc. Providing software and consulting services to solve hydrology and stormwater problems throughout the world.

2. Clear Creek Solutions Expertise We specialize in computer modeling of complex hydrologic and hydraulic systems. We have 30+ years of experience modeling hydrologic and stormwater problems. We created WWHM3 for Washington State Department of Ecology and adapted it to model San Francisco Bay Area and San Diego watersheds and stormwater facilities. We teach WWHM, BAHM, SDHM, and HSPF workshops.

3. In the beginning… Clear Creek Solutions was founded in 2005 by Doug Beyerlein and Joe Brascher.

4. Doug Beyerlein, P.E. Principal Engineer Doug started his career at Hydrocomp under the direction of hydrologic modeling pioneers Professor Ray Linsley and Dr. Norm Crawford. He later established the Washington offices of AQUA TERRA Consultants in 1992 before co-founding Clear Creek Solutions in 2005. He has written and presented landmark stormwater papers including “Why Standard Stormwater Mitigation Doesn’t Work” and “Effective Impervious Area: The Real Enemy”. Doug lives and works in Mill Creek, Washington.

5. Joe Brascher President Before co-founding Clear Creek Solutions Joe worked for the City of Olympia, Thurston County, and AQUA TERRA Consultants in Tumwater, Washington. Joe is the chief software architect for the creation of Western Washington Hydrology Model (WWHM3), Bay Area Hydrology Model (BAHM), and the San Diego Hydrology Model (SDHM). He has also pioneered the integration of the EPA SWMM and EPA HSPF models within the CCS software packages. Joe manages the Tumwater, Washington, office.

6. Clear Creek Solutions specializes in continuous simulation modeling. Continuous simulation hydrology models the entire hydrologic cycle for multiple years.
