Client: City of Olympia Public Works, Olympia, WA
The City of Olympia contracted with Clear Creek Solutions to provide hydrologic and hydraulic modeling services.
Our solutions were successful in reducing flooding in the Yauger Park drainage system caused by large events like the December 2007 flood.
The hydrologic and hydraulic model results for each alternative solution were summarized together with the required capital improvements in a report submitted to the City.
These alternative solutions included modeling the effects of management, facility improvements, and modifications to the Yauger Park stormwater drainage system.
Process and Solution
Different scenarios were run and compared with the calibrated model to view the effect the modification(s) on the drainage system.
The Western Washington Hydrology Model (WWHM) was used to model the stormwater runoff from the 1,022-acre Yauger Park drainage basin.
WWHM used HSPF to generate the stormwater runoff and SWMM to route the runoff through the City's conveyance system to Budd Inlet
