Overspray considerations include which areas?

• A. Hardscape and plant material
• B. Soil type
• C. Water hardness
• D. Wind speed

Answer: (A)

Overspray is water that leaves the intended irrigation zone and lands on surfaces outside the target area. When thinking about overspray, you focus on the spaces around the landscape that could receive unintended watering: hardscape surfaces like sidewalks, driveways, and patios, and plant material outside the designed plant beds that could be affected by extra moisture. Designing with these areas in mind helps you choose sprinkler locations, nozzle types, and patterns that keep water in the intended zones, reduce runoff, and protect non-target areas. Factors like soil type, water hardness, and wind speed matter for how water moves and how equipment performs, but they describe conditions that influence irrigation performance rather than the specific areas around the landscape that must be shielded from overspray.
