Snohomish County does not require native landscaping for homeowners, but Title 30 rewards it: development landscape plans that use Puget Sound indigenous species can lower the required evergreen share, and buffer enhancement with Pacific Northwest natives helps meet tree-canopy standards.
For new residential development in urban growth areas, SCC 30.25.016(6) requires replanted tree canopy to be at least 50 percent evergreen species, but that evergreen share drops to 37.5 percent when the deciduous mix is composed exclusively of species indigenous to the Puget Sound region (excluding Alder). Under SCC 30.25.016(8), an applicant may reduce canopy requirements by enhancing critical-area buffers through removing invasive species and noxious weeds and planting vegetation indigenous to the Pacific Northwest, spaced for maximum survivability. The county also runs a Native Plants program through its Noxious Weed / Surface Water programs. There is no mandate for private homeowners to plant natives, and no ordinance restricting a resident's plant choices (aside from prohibited noxious weeds).
No penalty for plant selection. These are development-plan incentives, not homeowner mandates; only prohibited noxious weeds are enforceable (RCW 17.10).
