Landscaping & Hardscaping in Ballard, Seattle
Quick answer
Ballard splits in two: till uplands at Loyal Heights and Sunset Hill, and filled former tideland near Salmon Bay that Seattle maps as liquefaction-prone. The alley grid usually lets a machine reach the back yard. We build patios, walls, cedar fencing, sod and irrigation, about forty minutes from Kent.

There are two Ballards under the pavement. North and west of about 65th, through Loyal Heights, Whittier Heights, Sunset Hill and out toward Crown Hill, you're on upland glacial till. Same hardpan we hit all over this side of the Sound. South and east it changes. Along Salmon Bay, the Ship Canal and the old industrial strip toward the Locks, a lot of the ground is fill, dumped over tideland and marsh a century ago. Seattle maps that lower corridor as liquefaction-prone. You feel the difference at the shovel. You hear about it again at the permit counter. And you can't tell which one you're standing on from the street.
Ballard was its own city until 1907 and the houses still say so. Ballard boxes and Craftsman bungalows from 1900 to 1930, sitting on narrow platted lots of three to five thousand square feet. Behind them, a full alley grid. That grid is the best thing about working in this neighborhood. Then two waves of change. Through the 2010s townhouses and rowhouses replaced single houses along the arterials, leaving back yards of four hundred square feet floored in compacted construction subgrade. In 2019 Seattle loosened its accessory dwelling rules, and backyard cottages went up across Ballard faster than anywhere else in the city. That changed what a Ballard back yard even is. So a lot of our work here is making sense of what's left. A narrow side run. A small paved court between the house and the DADU. A fence so two households aren't looking straight at each other.
Up on the upland the dig is familiar. Alderwood soil over till, hardpan around two feet, water sitting on top of it from November through March. Cobbles in the way. Down near the flats it's a different job. The water table is close, and a two-foot hole can fill with water on its own with no rain that week. The fill is whatever the mill and shipyard era left behind: wood debris, slag, brick, old timber cribbing, sometimes a length of buried rail. Base sections down there need geotextile separation, and bearing needs more thought than a textbook detail gives it. Old clay tile drains run through a lot of these yards. The people who put them in understood this rain perfectly well. Cut one by accident and you won't know about it until the next winter shows up as a wet lawn.
Alley access is why a Ballard project can often be built with a machine when the same project on Capitol Hill can't. A mini excavator will usually reach the back yard through the alley. That one fact takes real money off a patio or a wall, because the material and the spoil aren't moving by wheelbarrow. It isn't automatic though. Some alleys are narrow. Several are unpaved and turn to mush in February. Bins and parked cars block them. A newly built cottage may have eaten the turning room that used to be there. So we walk the alley before we quote, not after. Out at Sunset Hill and above Shilshole the wind comes off Puget Sound with salt in it, and gardens on those blocks need a tougher plant list than the sheltered streets around Adams and West Woodland.
What people ask for here is usable outdoor space in a small footprint, done right. A tight paver court with a gas fire bowl. Horizontal cedar fencing, which this neighborhood likes more than any other place we work. A raised bed that screens the alley without shrinking the yard. Sod on a two-hundred-square-foot lawn that actually roots, because we fixed the subgrade instead of covering it up. Planting swings between two extremes. Older lots keep a bigleaf maple throwing deep shade. The treeless townhouse parcels have no canopy at all. Sword fern, salal, carex and red twig dogwood handle the wet shade. Hebe, lavender, kinnikinnick and dwarf conifers take the wind and sun. Vine maple or a Japanese maple is usually the one specimen a yard this size can carry. Irrigation is drip and inline emitter tubing behind a tested backflow assembly, sized for beds you measure in feet.
Ground conditions in Ballard
Ballard has two different grounds, and you can't see the line between them from the street. The northern and western uplands, through Loyal Heights, Whittier Heights, Sunset Hill and Crown Hill, sit on Vashon glacial till. Usually Alderwood series soil with hardpan around two feet down. Water won't soak through that contact, so it perches all through the wet months. Yards stay saturated from November into March, then the same ground bakes dry by August. Expect cobbles in the dig. The lower ground south and east, along Salmon Bay, the Ship Canal and out toward the Locks, is largely artificial fill placed over former tideland and estuary in the mill and shipyard era. The City of Seattle maps that corridor as liquefaction-prone. Down there the water table is shallow and an open excavation can take on water by itself. The fill holds wood debris, slag, brick, timber cribbing and other legacy material, compacted unevenly, so bearing capacity is something we verify instead of assume. Older clay tile field drains cross many of these yards. On post-2010 townhouse and rowhouse parcels, and on lots that got a backyard cottage after Seattle relaxed its ADU rules in 2019, the native profile is usually gone. What's left is a few hundred square feet of compacted construction subgrade with no topsoil on it. Exposed blocks at Sunset Hill and above Shilshole take salt-carrying wind off Puget Sound.
Permits
Ballard permits through the City of Seattle. SDCI reviews the construction. SDOT controls the right of way, and that includes the alleys most projects here depend on. Retaining walls over 4 feet, measured from the bottom of the footing to the top of the wall, need a permit with stamped structural engineering. A wall of any height gets the same treatment if it holds back a surcharge from a slope, a parking pad or an adjacent foundation. The local wrinkle is the liquefaction-prone mapping along the Salmon Bay and Ship Canal corridor, which is part of Seattle Environmentally Critical Areas. On those parcels the city can require geotechnical input for a structure that would be routine up on the upland, and bearing and settlement questions get real scrutiny. Seattle stormwater rules currently catch projects that add or replace roughly 750 square feet or more of hard surface. On a small Ballard lot a patio, a side walk and an alley apron can reach that together. Fences below the code height threshold are generally exempt from a building permit, but zoning still governs. Height is limited more tightly inside the front setback than at the rear, and a fence on a corner lot has sight-triangle rules of its own. Adding or altering a backyard cottage brings in lot coverage, setback and hard-surface limits, and those decide how much yard you can pave. Removing most sizeable trees on a developed lot needs a permit under the 2023 tree ordinance. The Ballard Avenue Landmark District applies to the historic commercial core, and shoreline rules apply near Shilshole and Salmon Bay. Thresholds and mapping change, so we confirm the current numbers with the city at permit time.

Ballard: common questions
Can you get a machine into my back yard through the alley?
Usually, and it matters to the price. A mini excavator that can reach the back yard through the alley takes most of the hand labor out of a patio or a wall. That's why Ballard projects often cost less than the same build on a Capitol Hill lot. We don't assume it though. Some alleys are unpaved and soften badly in winter. Some are too narrow to turn a trailer. Bins and parked cars block others. A recently built cottage may have taken the maneuvering room. We walk the alley on the first visit and tell you which way the job is going to be built.
I am adding a backyard cottage. When should the landscaping get designed?
Before the cottage is finished. Ideally before the site plan is locked. Ballard has more DADUs than anywhere else we work, and the yard left over afterward is usually a few hundred square feet of compacted construction subgrade. No topsoil, no drainage plan, and two households sharing sightlines. Settle the paved court, the privacy fence line, the drainage route and the utility sleeves while the ground is already open. That costs far less than trenching through a finished yard later. Lot coverage and hard-surface limits count the cottage and the paving together too, so the two decisions are linked whether or not they get made together.
My lot is in the liquefaction-prone area near Salmon Bay. Does that affect a patio?
A flat at-grade patio, rarely. A wall or anything carrying load, often yes. That corridor is filled former tideland. The fill can be loose, wood-laden and unevenly compacted, and Seattle maps it as an Environmentally Critical Area for liquefaction. On those parcels a structure that would be routine up in Loyal Heights may need geotechnical input. Settlement is a genuine risk down there. So we do a few things differently. We verify bearing. We use geotextile separation in the base section, build in thinner lifts, and design for the shallow water table.
Why does my yard stay wet all winter?
Depends which Ballard you're in. Up on the till at Loyal Heights or Sunset Hill it's hardpan. About two feet of soil over dense glacial till, and water can't pass through it, so the rain perches and stalls. Down toward the flats it's a shallow water table in filled ground. Sometimes it's a clay tile drain from the 1920s that finally collapsed or got cut during a remodel. Three causes, three different fixes. So we probe the profile and check for existing drain lines before we propose anything. A French drain in the wrong spot may solve nothing.
Do I need a permit for a new fence in Ballard?
Usually not a building permit, as long as it stays under the code height threshold. Zoning still governs though. Seattle limits fence height more tightly inside the front setback than in the side and rear yards. Corner lots have sight-triangle requirements at the driveway and the intersection. Anything in the alley or the planting strip is right-of-way work, which belongs to SDOT rather than SDCI. Property lines on these narrow old Ballard plats are often not where people assume, so we confirm the line before setting posts. And we check the current height rules with the city instead of quoting you a number that may have changed.
