Artificial Turf Installation in West Seattle

Usually, with the drainage designed rather than assumed. The consideration is that a turf base is several inches of free-draining rock, which on sloping ground becomes a path for water — and on slide-sensitive ground, concentrating water where it did not previously go is the mechanism that causes problems over successive wet seasons. That does not rule turf out; it means the base needs a defined outfall and, where flow arrives from uphill, an interception drain above it. We check the parcel against the city ECA map before quoting so the process is known up front.

Because the rainfall figure describes the winter rather than the growing season. Almost all of Seattle's 38 inches falls between October and March, and July and August are genuinely dry. A west-facing plateau or bluff garden takes the strongest afternoon sun and the most wind of anywhere in the city, so it loses moisture far faster than a sheltered east-facing equivalent. That is the specific case where a lawn struggles at both ends of the year — waterlogged in winter, scorched in August — and where turf removes both problems at once.

Not the turf itself, which is unaffected by salt-laden wind. What it affects is the metalwork: edge restraints, fixing pins, staples and any fittings holding the perimeter down will corrode noticeably faster in an exposed Alki or Fauntleroy position than the same components a mile inland. Since a lifting edge is the most common turf fault anywhere, that matters here more than it sounds. The adjustment is specification rather than design — better-grade fixings and restraint on anything at the perimeter.

Yes, but the project is terracing with turf as its surface rather than a turf install. Creating a genuinely level, safe play area on a fall means a retaining edge to hold the level, drainage behind it, a compacted free-draining base and then the turf, with a shock pad underneath if children are the reason. Priced as one integrated project that is straightforward and durable. Priced as a turf quote with a wall added later, the two rarely meet properly and the join is where it fails.
