Irrigation & Sprinkler Systems in Kirkland, WA

In shorter, repeated cycles rather than one long run, and zoned by elevation. Water applied to a slope faster than the soil can absorb it simply runs downhill, so a single long cycle leaves the upper ground dry and the toe waterlogged while delivering exactly the volume the controller was told to. Splitting the same total into two or three shorter applications with a gap between lets each one soak in. Combined with separate zones for upper and lower terraces, which genuinely dry at different rates, that fixes most sloped-garden watering problems without any extra water.

Yes. Kirkland is a Cascade Water Alliance member city, part of a regional wholesale arrangement serving several Eastside cities, rather than being supplied by Seattle Public Utilities. For a homeowner the practical difference is in conservation programmes and rate structures rather than in the water arriving at the tap. Since those arrangements change, we design for efficiency directly instead of relying on any particular programme — correct zoning, drip on planted areas, and weather-responsive control that skips a cycle when it has rained.

Usually, and it is worth doing before any excavation rather than after. Older Kirkland systems frequently have zones nobody has mapped, valves buried under planting that has grown over them, and wiring runs of unknown route. We locate what we can by running each zone and observing, find valve boxes, and identify which heads belong to which circuit. That produces a working map. It also frequently reveals the real problem — a zone that has been disconnected for years, or two zones bridged into one — which is often cheaper to fix than anyone expected.

Almost everything about how planted areas perform on a slope. Sprinklers throwing water onto a terraced bed lose a substantial share to runoff and evaporation before it reaches a root, and they wet foliage, which in a damp climate encourages fungal problems. Drip lines laid to the planting deliver water at the root directly, so nothing runs off the terrace edge and nothing is wasted between plants. On a stepped Kirkland garden it is usually the single biggest improvement available, and it uses less water while doing it.
