Are pavers a good choice for walkways in Seattle?
Pavers make some of the best walkways for Seattle-area rain: they stay put, drain well when built right, and a sunken section can be lifted and reset. What keeps a path level and safe is underneath and around it: a packed gravel base, firm edges, a slight slope, and regular moss control.
Pavers are individual blocks, usually concrete or stone, laid side by side like a puzzle. A paver walkway can lead to your front door, link a driveway to a side gate, or wind through a garden to a patio or deck. This guide explains in plain terms how to build one that lasts through our wet season.
Paver walkways in Seattle: key facts
| Question | Short answer |
|---|---|
| What keeps a path from sinking? | A packed gravel base under the pavers, built up in layers |
| What keeps pavers from spreading apart? | A firm edge (edge restraint) along both sides of the path |
| Which way should it slope? | Slightly to one side, away from the house. Near the house, the code requires at least a 2% slope, about 1/4 inch per foot |
| Do walkways count toward Seattle's rainwater rules? | Yes. Walkways, patios, and driveways all count as hard surface; past 750 sq ft added or replaced, the rules apply |
| Biggest problem in our climate | Moss in the gaps, which holds water and makes the surface slippery |
Pavers, concrete, or gravel: which path is right for you?
| Paver walkway | Poured concrete walkway | Gravel path | |
|---|---|---|---|
| How it feels to walk on | Firm and even | Firm and even | Loose underfoot |
| When the ground settles | A low spot can be lifted and reset | The slab can crack; repairs often show | Easy to rake level |
| Look | Patterns, borders, colors | Clean and simple | Casual, natural |
| Wheelbarrows, strollers, wheelchairs | Rolls well | Rolls well | Hard to push through |
| Upkeep in our rain | Clear moss from gaps, refill sand | Occasional cleaning | Top up gravel, pull weeds |
For a front walk or a path you use every day, pavers or concrete are usually the better choice. Gravel suits a casual garden path you walk on occasionally.
How is a paver walkway built to last?
A walkway looks simple, but most of the work is below the surface.
- Mark the path and dig it out. Soft topsoil and roots come out, because they squash down and rot.
- Shape the ground for drainage. The dirt underneath is shaped so the finished path tilts slightly to one side, away from the house.
- Build a packed gravel base. Crushed stone goes in a few inches at a time, and each layer is packed hard with a machine. This keeps the path from sinking when the ground is soaked.
- Add a thin, level layer of sand for the pavers to sit on.
- Lay the pavers and lock both edges. A firm border runs along each side so the path can't spread apart. Paths are narrow, so this step matters even more than on a patio.
- Fill the gaps with sand and pack it in, so the pavers lock together.
A tip on width: a path wide enough for two people to walk side by side, or for a wheelbarrow, feels far more comfortable than a narrow one. We'll measure your space and suggest a width that fits.
Where does the rainwater go?
A walkway collects rain along its whole length, so the water needs somewhere to go.
- Tilt it to one side. A slight sideways slope sends water off the path instead of letting it sit in puddles.
- Send water away from the house. The building code requires any hard surface within 10 feet of the house to slope at least 2% away from the building, which is about 1/4 inch of drop for every foot.
- Give it a landing spot. Water should run onto a lawn or planting bed, not against the foundation or into a neighbor's yard.
- Watch the downspouts. A downspout pouring onto the path washes the sand out of the gaps and the gravel out of the base.
What rules apply to a paver walkway in Seattle?
Most paver walkways at ground level are simple projects, but two things are worth knowing.
Seattle's rainwater rules count walkways. When a project adds or replaces more than 750 square feet of hard surface, Seattle's stormwater rules apply, and you'll need a plan for where the extra rainwater goes. That total includes everything in the same project: a new walkway, a patio, and a driveway together can pass 750 square feet faster than you'd expect.
"Permeable" pavers still count. Permeable pavers have wider gaps filled with small gravel, so rain soaks through. Even so, Washington's rainwater rules still count them as hard surface.
Two more things to check:
- The area near the street belongs to the city. If your path connects to the public sidewalk or crosses the planting strip, check with the city before working in that area.
- Steep slopes. If your lot is on a mapped steep slope, check with the city before digging.

How do you keep a paver walkway safe in our rain?
A wet, mossy path is a slipping hazard, especially in shaded yards under evergreens.
| What to do | When | Why it helps |
|---|---|---|
| Sweep up leaves and needles | Often in fall | Wet leaves get slippery and feed moss |
| Remove moss from the gaps | Fall and spring | Moss is slick and pushes the sand out |
| Refill the sand between pavers | Whenever the gaps look low | Keeps the pavers tight and level |
| Fix sunken or tipped pavers | As soon as you notice them | A raised edge is a tripping hazard |
| Trim plants and branches back | As needed | More sun and air help the path dry out |
Choosing a paver with a slightly textured surface also helps with grip when it's wet. Go easy with a pressure washer: a strong blast can wash the sand out of the gaps.
Walkways that connect your outdoor space
A walkway is often the piece that ties everything together: from the driveway to the front door, from the back door to a patio, or down to a deck. Planning them together means matching materials and levels and one drainage plan for the whole yard. See our guide to paver patios in Seattle and our deck and patio services.
FAQ
Are pavers good for a front walkway in Seattle?
Yes. Pavers stay firm and even, handle ground movement well, and a sunken section can be fixed without redoing the whole path. Build them on a packed gravel base with firm edges.
Why do paver walkways sink?
Usually because the base underneath wasn't deep or packed enough, or water is running under the path. A packed gravel base and good drainage prevent it.
How do I keep my paver walkway from getting slippery?
Sweep up leaves often, remove moss from the gaps, and let in more sun by trimming plants back. Textured pavers also grip better when wet.
Do I need a permit for a paver walkway in Seattle?
A walkway at ground level is usually a simple project. If your project adds or replaces more than 750 square feet of hard surface, Seattle's rainwater rules apply, and work in the area near the street needs a check with the city first.
Do permeable pavers count as hard surface?
Yes. Even though water soaks through them, Washington's rainwater rules count permeable pavers as hard surface.
Which way should a walkway slope?
Slightly to one side, and always away from the house. Near the house, the code requires at least a 2% slope, about 1/4 inch per foot.
