Artificial Turf Installation in Shoreline, WA

Access, almost entirely. The largest variable cost is not the turf but the labour of excavating and moving several tons of base material. On a Seattle city lot where that goes through a three-foot gate by barrow, it can exceed the cost of the product itself. On a Shoreline lot with room to bring a machine to the work and drop material beside it, the same install takes substantially fewer crew hours. Same specification, same product, genuinely different labour — which is why a per-square-foot figure from one area does not transfer to the other.

More, and this is the counter-intuitive part. Sloped ground gives surface water somewhere to run; flat ground on glacial till gives it nowhere at all. Water passes through the turf backing, travels down through the base, reaches the hardpan and stops — and on a level lot there is no gradient to carry it sideways. So a flat Shoreline lawn needs the base built as a genuine drainage layer graded to a fall, with a route out, rather than simply a levelling course. That is the single most important line in the specification here.

Absolutely, and on a lot this size it is what makes the garden work. Turf handles the part of a garden that takes wear and needs to be usable in February; planting handles everything else, and it is where the interest actually comes from. The common mistake on a big lot is turfing a very large area and leaving a thin border round the edge, which reads as flat and featureless. A defined turf area with genuinely deep planted boundaries costs less overall and looks considerably better from the house.

The base becomes the question rather than the turf. A conventional excavation for a turf base is six inches or more of material removed, and under an established north-end maple or fir that means cutting through the root plate — most of which sits in the top foot of soil and spreads well beyond the canopy. Options are shifting the turf area outside the critical root zone, using a shallower build-up close to the tree, or leaving a planted or mulched area under the canopy where turf would struggle with needle drop anyway. The last of those is usually the better garden as well.
