Pierce County encourages native and drought-tolerant plantings and requires native-vegetation retention on many development sites, but homeowners are free to choose their own yard plants; the mandates apply to development landscape and clearing plans, not existing private landscaping.
No rule forces residents to plant native species, and homeowners may landscape ordinary yards as they wish. Where the county addresses native plants, it favors them in the development context. PCC 18J.15.020 (Site Clearing) sets minimum native-vegetation retention percentages by zone for projects within open-space corridors, from 15 percent in urban center zones up to 65 percent in rural and resource zones, prioritizing critical areas and buffers. In design standards, county code encourages native and drought-tolerant material: for screening around noise barriers, PCC 18J.15.070 states such groundcover 'is encouraged but not required.' So native landscaping is promoted and sometimes retention is mandated, but plant choice in an existing private yard is not dictated by county code.
For regulated development, failing to meet native-vegetation retention percentages under PCC 18J.15.020 or required landscape-plan plantings violates Title 18J, enforced by Planning & Public Works through corrective planting. There is no penalty for a homeowner's ornamental plant choices.
