Oregon Landscape Construction Professional, Individual (All Phase Plus Backflow) License (OR) Oregon’s All Phase Plus Backflow license encompasses landscape grading, irrigation, and water safety systems in a single credential—unlike fragmented multi-cert paths in other states. This consolidation means one exam covers soil preparation, sprinkler design, and backflow prevention devices. Competitors holding separate certifications still need additional training to match this integrated scope, making Oregon’s streamlined approach uniquely efficient for professionals handling complete site water management.
