The Little Bear Creek basin in south Snohomish County was selected as the focus of this plan, with Department of Ecology approval. Key reasons for this selection were:
In the course of this study, the County identified a baseline for water quality conditions and options to manage future stormwater in a manner that will protect the basin’s water quality and habitat resources for the future.
The study found that dissolved copper and dissolved zinc would not present problems for future water quality. However, the other parameters (temperature, fecal coliform, and flow through a correlation with B-IBI) would require further mitigation to achieve water quality standards and targets in the future.
Following submittal of the final basin plan to the Department of Ecology, the County is committed to maintaining compliance with the Phase I Municipal Stormwater Permit. The information generated through this planning effort (assessment and basin plan) provides a valuable guide for the County’s ongoing projects and programs to improve water quality in the Little Bear Creek watershed. The permit itself does not require the implementation of this plan. However, the County will continue to work on projects in the Little Bear Creek Basin that are part of the Public Works Surface Water Management (SWM) capital improvement and education and outreach programs, incorporating the Plan guidance as projects are prioritized.
