The City of North Bend is situated within the Three Forks area of the Upper Snoqualmie River Valley. Due to this location, the city experiences some flooding and runoff challenges. Increased development in the city generates increased stormwater runoff which at times can not be handled by some undersized drainage systems. Short of enlarging the system when opportunity exists, the city maximizes the use of its current system capacity through continuous maintenance.
Implementation of a Stormwater Utility In 2001, the City completed a comprehensive plan of its stormwater system and subsequently created a stormwater utility to help finance the needed operation, maintenance, and improvement costs associated with the system.
The City of North Bend has adopted the 2009 King County Surface Water Design Manual. This Manual provides codes and requirements that applicants, builders and developers are required to meet for new projects inside City Limits. Some of these requirements include safe conveyance, flow control, and water quality treatment.
