Client: City of Bellingham Storm and Surface Water Utility, Bellingham, WA

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.

The Western Washington Hydrology Model (WWHM) was used to model the stormwater runoff from the City of Bellingham watersheds. WWHM used HSPF to generate the stormwater runoff and PCSWMM to route the runoff through the City's conveyance system to the streams flowing to Bellingham Bay.

Flood frequency and other flow statistics were generated from the WWHM results. Capital improvements were included in the models to evaluate their performance prior to determining their recommended priority for implementation.
