If an obstacle not shown on the irrigation plan is encountered, the technician can alter the design with approval from whom?

• A. The licensed irrigator
• B. The property owner
• C. City inspector
• D. The supervisor

Answer: (A)

When you hit an obstacle not shown on the plan, changes to the irrigation design must be approved by the licensed irrigator who is responsible for the system. This professional has the authority and accountability to modify the design to maintain performance, water efficiency, and code compliance, and to document the change properly. The property owner may authorize installation work, but they don’t authorize design changes. A city inspector enforces rules and can require revisions, but they don’t grant design modifications. The supervisor oversees the crew on site, but the actual approval authority for design changes rests with the licensed irrigator.
