Roseville, CA Invasive Plant Rules: Prohibited Species (2026)

040 defines an invasive plant species as one not historically found in California that spreads outside cultivated areas and can damage environmental or economic resources, and notes that county agricultural agencies may separately regulate such species as noxious weeds, with lists maintained by the California Invasive Plant Inventory and the USDA invasive and noxious weeds database. 050(B)(4)(g)(ix) folds this concern into the mandatory landscape design plan review, directing applicants to avoid species listed by the California Invasive Plant Council alongside other design considerations like property-line delineation and defensible-space planning.

010(C)(5) links avoiding invasive plants to protecting existing habitat and creating new habitat through native and climate-adapted planting choices. Unlike the chapter's turf percentages or irrigation equipment rules, the invasive-species clause is written as guidance rather than a mandatory standard, so it does not by itself give the environmental utilities director grounds to reject a landscape package the way an oversized turf area or a missing rain sensor would.
