Landscaping & Hardscaping in SeaTac, WA

SeaTac incorporated in 1990, and the airport is the reason. Residents around the field wanted a seat at the table on land use, and the city they created is about ten square miles with a very large share of that occupied by Port of Seattle property. What is left is residential in bands wrapped around the airfield: Riverton Heights and Bow Lake at the north end, McMicken Heights along the eastern shoulder above the Duwamish valley, and Angle Lake and Madrona Park to the south. Understanding which band a house sits in tells you most of what you need to know before the walkthrough.

The housing is modest and mostly mid-century. Small wartime houses and 1950s and 1960s ramblers on seven to ten thousand square foot lots, plenty of them held by the same family for decades, alongside a substantial rental and small-landlord share. Entire blocks are also missing. The Port acquired and removed hundreds of homes through the noise remedy and third-runway programs in the 1980s and 1990s, and North SeaTac Park is the result, with old street stubs and driveway aprons still readable in the grass. Since the light rail station at South 200th opened in 2016, townhomes have filled in around the station area on parcels that used to hold one house and a big back lawn. Angle Lake is the exception to all of it: a small kettle lake ringed with docks, short lots pitching down to the water and almost nowhere to swing a machine.

Under the sod it is Vashon till at 350 to 400 feet of elevation. Roughly two feet of Alderwood gravelly sandy loam sitting on a cemented hardpan a shovel rings off, with pockets of looser Everett gravelly sand where outwash comes through around Riverton Heights. People read the words sandy loam and expect drainage. What they get is a perched water table and one corner of the yard that stays soft from November to March. The lakes here, Angle, Bow, Tub and Lora, are relict glacial kettles in closed basins, so the ground near them holds water higher and longer than the map suggests, which matters for footings and for what survives planted in the low corner. Two buried surprises are common in this housing vintage: abandoned septic drainfields on streets that got sewer late, and steel heating oil tanks under 1950s houses that converted to gas. We probe before we trench, because finding either with an excavator bucket is an expensive way to find it.

Nothing about a SeaTac yard is separable from the airfield, and that shows up three ways. Height first. FAA obstruction surfaces and the city airport height provisions constrain tall objects under the approach corridors, and the Port runs an obstruction program that has topped and removed trees in those paths, so planting a Douglas fir that intends to be a hundred feet tall under a final approach is buying a future removal bill. Second, wildlife. FAA guidance discourages bird attractants close to an airfield, so on the parcels nearest the fence line we keep large fruiting masses and open standing water off the plan and use a pondless basalt column or a recirculating fountain instead of a pond. Third, noise, where honesty matters. A solid cedar fence and a dense evergreen screen will genuinely cut tire and traffic noise off International Boulevard or Military Road, and they change how enclosed a yard feels. No hedge stops a 737 at fifteen hundred feet. We say that up front rather than selling planting as a sound wall.

What people here actually ask for is practical rather than showy. Privacy fencing is the single most requested item in the city, usually cedar, usually along an arterial or a shared line that lost its 1970s posts in a south wind. Front yards on rental properties that need to be low maintenance and stay that way. A back patio sized for real family gatherings, which in SeaTac often means the paved area matters more than the lawn does. Repairs on sprinkler systems installed in the seventies and eighties before backflow prevention was standard. One street-level wrinkle: many SeaTac roads never received curb, gutter and storm pipe, so runoff is still handled in roadside ditches, and a new or widened driveway crossing one needs a right-of-way permit and a correctly sized culvert. Filling the ditch is not an option no matter how tempting it looks. Blue Landscaping Services designs in-house and self-performs the hardscape rather than handing it off, and we carry Washington contractor registration BLUELLS880K2 with a $12,000 bond and $1M liability coverage behind it. From the Kent shop we are fifteen to twenty minutes out.
