Bothell City Council was scheduled to receive initial briefing on Critical Areas Ordinance update, including a proposed 100-foot stream buffer

What the records say

In materials published ahead of the Sept. 9, 2025 Bothell City Council meeting, the record said the council was scheduled to receive initial information on a mandatory update to the Critical Areas Ordinance (CAO), or Bothell Municipal Code chapter 14.04 ¹. The update was planned to be finished by Dec. 31, 2025 ¹. The record said no action was required at that session ¹. The record described a proposed moderate change to minimum required stream buffers and associated vegetation requirements ¹. The accompanying status table said staff were proposing a standard 100-foot buffer on all streams, with a 33% buffer increase where vegetation buffer standards are not met; current code requires 100-foot buffers on salmonid-bearing streams, 75 feet on perennial non-salmonid streams, and 50 feet on intermittent non-salmonid streams ¹. The update also included potential increases to the locally established SEPA exemption thresholds in BMC chapter 14.02 ¹. SEPA stands for the State Environmental Policy Act ¹. The record listed questions the City Council may wish to consider, including whether it supported staff's approach to the scope and degree of moderate and minor changes, whether it had suggestions on the stream buffer proposal, and how recommended flexibility in the SEPA project threshold process aligned with the council's development approach ¹.

Why it matters

The proposed stream buffer and vegetation changes could affect how close development can come to streams and what plants must remain along them, which matters to property owners, builders, and residents concerned about water quality and habitat ¹. The SEPA threshold discussion could change which projects must go through environmental review ¹. Because this was a pre-meeting record, the available records do not establish the meeting's outcome or any final council direction.
