State issues temporary permit for limited flood control work on Perrinville Creek

The State Department of Fish and Wildlife issued a temporary permit for the City of Edmonds to clear debris from Perrinville Creek to address imminent flooding risks before the rainy season. This work must be completed by January 13, 2026, and focuses on clearing sediment and debris without allowing modifications to existing flood control structures. City Engineer Mike DeLilla stated that this action is a stopgap measure rather than part of a comprehensive flood control plan. Local engineer Bill Lider highlighted that previous residential permits in the floodplain created ongoing flooding dangers. He explained that sediment traps built by the city require constant maintenance to prevent overwhelming the diversion system.

Environmentalist Joe Scordino criticized the diversion structures for impeding fish passage, arguing they were improperly permitted and detrimental to salmon habitat. The situation illustrates the ongoing conflict between flood control measures and environmental concerns, which has persisted for decades. As work begins, residents remain vigilant about the potential for flooding and the ecological implications of the structures.
