Landscaping in Magnolia, Seattle

A significant number are, particularly along the western and southern bluff and the slopes running down to Interbay, and it is genuinely not something you can judge by looking. Seattle defines a steep slope as 40% or more grade over ten feet of vertical change and applies fifteen-foot buffers at both top and toe, with separate designations for landslide-prone and potential slide areas. Inside any of them the four-foot wall exemption stops applying entirely. We look your specific parcel up on the city map before quoting, so the permit position is a known cost at the start rather than a discovery halfway through.

Usually, but it takes deliberate design rather than defaulting to the obvious solution. One tall wall built close to the house is the cheapest thing to draw and the fastest way to put a barrier across the sightline you paid for. The alternative is stepping the fall in two or three lower terraces set further out, which keeps the eye travelling down and over rather than stopping at a face. It also usually costs less, because shorter walls avoid the engineering and permit thresholds a single tall one triggers. On a Magnolia view lot we would rather spend the first site visit standing at the window than at the property line.

Because on unstable ground, water is not just a nuisance — it is the mechanism. Saturated soil is heavier, has less internal strength, and is what turns a slope that has stood for decades into one that moves. On the bluff that makes uncontrolled surface water, a downspout discharging over the edge, or an old drain that has silted up into genuine risk factors rather than maintenance items. Any hardscape we build here is designed around where the water leaves the property first, and on several Magnolia projects the drainage has been the whole job with the landscaping as the visible byproduct.

Noticeably more than a sheltered garden a mile inland, and it catches people out in a city with Seattle's reputation. Almost all of our 38 inches of rain falls between October and March, and July and August are genuinely dry. A west-facing Magnolia garden takes the strongest afternoon sun and the most wind of almost anywhere in the city, so it loses moisture much faster through those two months. Planting that thrives in a shaded Wallingford back garden will struggle here. We tend to specify tougher, more exposure-tolerant planting on the bluff side and zone irrigation separately for the exposed beds.
