SWMM5 and HSPF modeling of the Lyon Creek watershed. This included flood analysis and by-pass pipe sizing.
Clear Creek Solutions has provide hydrologic modeling services to the Edwards Aquifer Authority of San Antonio, Texas, including computation of recharge to the Edwards Aquifer, comparison of recharge estimates based on different precipitation data sources, reviewing and analyzing results, and creating a Windows-version of HSPF for the nine major basins that cross the Edwards Aquifer.
The University of Washington Extension contracted with Clear Creek Solutions to provide instruction for a series of three workshops on how to model low impact development (LID) facilities and practices using the Western Washington Hydrology Model (WWHM).

The three LID workshops focused on bioretention/rain gardens, permeable pavement, and green roofs.
The City of Bellingham contracted with Clear Creek Solutions to provide hydrologic and hydraulic modeling services to develop a prioritized list of capital improvements related to drainage problems throughout the city.

The hydrologic and hydraulic model results for each study area were summarized together with the proposed capital improvements in a comprehensive stormwater management plan.
Costco's development of a new store in south Snohomish County, just north of Woodinville, required innovative strategies and analysis to protect adjacent Little Bear Creek. The Costco underground stormwater storage facilities reduce peak flows in Little Bear Creek.

The Costco store site is located on 14.38 acres between SR 522 and Highway 9. An additional 2.35 acres of Highway 9 improvements was planned along the store's frontage.
Clark County contracted with Otak to update the County's stormwater ordinance. As part of this work Clear Creek Solutions was hired to produce HSPF calibrations of two watersheds in the county. The calibrated HSPF parameter values were then used to update the Western Washington Hydrology Model (WWHM) for Clark County.

Joe Brascher and Doug Beyerlein of Clear Creek Solutions provided the King County Department of Natural Resources and Parks, Water and Land Resources Division with HSPF modeling services to develop a water quantity and quality analysis models for two topographic basins - the Green-Duwamish and the Lake Washington-Ship Canal basins. These models support the two major projects: the Green-Duwamish Water Quality Assessment (GDWQA) and the Sammamish-Washington Analysis and Modeling Program (SWAMP).
The City of Edmonds contracted with the a group of consultants, including Clear Creek Solutions, to prepare a strategic action plan that will address issues related to water quantity and water quality within the Lake Ballinger-McAleer Creek drainage basin. The cities of Edmonds, Lake Forest Park, Lynnwood, Mountlake Terrace, and Shoreline together with Snohomish County formed the Watershed Forum to guide the development of the McAleer Strategic Action Plan.
The City of Wenatchee SWMM modeling study determined conveyance system capacity and upgrades at various locations throughout the city's urban stormwater drainage network. The SWMM modeling was conducted by Mr. Joseph Brascher. Six different scenarios were modeled including both current and future land use conditions. SWMM was run on a continuous basis using 40 years of hourly rainfall data. Output from SWMM was then used to compute flood frequency information for each culvert in the drainage system network.
The City of Olympia contracted with Clear Creek Solutions to provide hydrologic and hydraulic modeling services to develop solutions to reduce flooding in the Yauger Park drainage system caused by large events like the December 2007 flood.
