Snohomish County Planning and Development Services (PDS) is in the early stages of a project to study part of the County adjacent to the fast-growing south-easterly edge of the Southwest Urban Growth Area (SWUGA) – see map below.

The project is not proposing changes to land use, polices, or UGA boundaries. It is a high-level study to provide background about existing conditions in the SWUGA and the study area, and opportunities and constraints to consider if adjustments to the boundary are under review in the future.

For more information about this study, the scope of work and project flow chart and timeline are linked below.
