Clear Creek Solutions, Inc.
Providing software and consulting
services to solve hydrology and
stormwater problems throughout the
world.
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.
In the beginning…
Clear Creek Solutions was founded in
2005 by Doug Beyerlein and Joe
Brascher.
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.
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.
Clear Creek Solutions specializes in
continuous simulation modeling.
Continuous simulation hydrology models the entire
hydrologic cycle for multiple years.

CCS software uses continuous simulation hydrology to
compute stormwater runoff for both predevelopment
and post-development conditions.
