Paver Patios & Retaining Walls in Maple Valley, WA
Kairos Landscapes builds paver patios, walkways, driveways and retaining walls for Maple Valley homeowners, including properties near Elk Run, Rock Creek Meadows and Lake Wilderness.
Build a yard that works better in Northwest weather. Many local projects need more than a material choice. Lot coverage, drainage, grade changes and protected trees can affect what fits. We check those conditions before the plan is final.

Paver Patios, Walkways & Driveways
The base under the pavers decides how the finished surface holds up. Maple Valley's wet season makes excavation, compaction and drainage part of the main build, not an afterthought.
PAVER PATIOS
Build the Patio Around How You Use the Yard
Dining, seating, a grill and a fire feature all need different amounts of room. The layout comes first. Paver size and pattern come after the use, access and drainage are clear.
Pavers also make future repairs less disruptive. If one area settles, that section can be lifted, corrected and reset without tearing out an entire slab.
We compact the base in layers and give winter water a planned route away from the house and hard surface.

WALKWAYS AND DRIVEWAYS
Plan the Largest Hard Surface First
A driveway can take up a large share of the hard-surface area on a residential lot. Planning it with a future patio or walkway can prevent the first phase from limiting the second.
Driveways also need a deeper base than most patios. Vehicle loads, edge restraint and drainage need to be settled before the surface goes down.
Paver walkways
Defined routes from the driveway to entries, side yards and patios.
Paver driveways
Deeper base preparation and pavers rated for vehicle traffic.
RETAINING WALLS
Turn a Grade Change Into Usable Space
A retaining wall can make a sloped yard easier to use while supporting a patio, planting area or lawn above it.
A wall over four feet is measured from the bottom of the footing to the top. A shorter wall can also need review when it supports added load behind it, such as a driveway or another wall.
Drainage rock, filter fabric and a drain route help keep winter water from building pressure behind the wall.

CREATING A TIMELESS LANDSCAPE
We think far beyond today. To truly love your outdoor spaces, you need features, materials, and fine details that can be enjoyed for many years to come.
ARTIFICIAL TURF
A Practical Add-On for Mud, Shade & Dog Areas
Turf works well where grass keeps failing, including shaded side yards, dog runs and areas that stay muddy through the wet season.
The base and drainage under the turf still matter. A poor base can hold water, settle or leave low spots.
Maple Valley's code doesn't clearly classify artificial turf for coverage and drainage. Kairos can confirm the treatment for a coverage-sensitive project before the plan is final.
ADD-ONS
Finish the Hardscape While the Site is Open
Seating, fire, lighting and kitchen features are easier to plan with the patio than after the base is closed and the finished surface is in place.
Seat Walls
Use the same paver family around the patio edge for permanent seating and a defined border.
Fire Pits & Fire Tables
Maple Valley is served by Puget Sound Regional Fire Authority. Recreational fire rules and seasonal burn bans can affect wood-burning features. Gas and propane devices remain usable in more restricted conditions.
Outdoor Lighting
Plan path, step and wall lighting before pavers are set so conduit and wiring routes don't require cutting finished work later.
Outdoor Kitchens
Set the footprint with the patio and run gas, power and plumbing before the surface is finished.

PROJECT PROCESS
From Site Visit to Finished Hardscape
A Maple Valley project starts with the lot. Measurements, grade, access, drainage and local review triggers are checked before materials are locked in.
STEP 01
Site Visit
Walk the property, measure the area and talk through how you want to use it.
STEP 02
Plan & Materials
Set the footprint, material family, drainage approach and connected features.
STEP 03
City & Site Check
Check zoning, coverage, trees, grade and permit triggers that can affect the work.
STEP 04
Build & Walkthrough
Prepare the base, install the work, clean the site and review the finished project with you.
MAPLE VALLEY FAQS
Maple Valley Hardscape Questions
Do permeable pavers help me avoid Maple Valley stormwater thresholds?
Seating, fire, lighting and kitchen features are easier to plan with the patio than after the base is closed and the finished surface is in place.
Do I need a permit for a retaining wall in Maple Valley?
A wall over four feet, measured from the bottom of the footing to the top, can require a building permit. A shorter wall that supports added load behind it can also require review. Wall location, critical areas and public-right-of-way visibility can add other requirements.
How much impervious surface is allowed on a Maple Valley residential lot?
The cap depends on the property's residential zone. Current city code lists 55% in R-4, 70% in R-6, 75% in R-8 and 80% in R-12, R-18 and R-24.
When can a patio or driveway trigger stormwater requirements?
Flow-control BMP requirements can begin at 2,000 square feet of new plus replaced impervious surface or 7,000 square feet of land-disturbing activity. At 5,000 square feet of new plus replaced impervious surface, flow-control facilities can be required.
Can I remove a tree to make room for a patio?
A landmark tree needs a clearing and grading permit before removal. A significant tree on a lot of at least one-half acre can also need a permit. Trees retained or planted under an approved plan, tree protection area or other development condition can be protected regardless of their current size.
What happens if a protected tree becomes an emergency hazard?
Maple Valley allows emergency removal when a tree poses imminent danger. The condition must be documented before removal, the documentation must reach the city within seven days and a post-removal permit is required.
Can I have a fire pit in Maple Valley?
Recreational fires are allowed under Puget Sound Regional Fire Authority rules when no ban prohibits them. Clearance rules apply. Stage 2 fire-safety bans prohibit recreational fires, while approved manufactured gas and propane outdoor devices can still be allowed under the ban rules.

Two Local Rules Can Change the Plan Early
Maple Valley has site rules that can change patio, driveway and wall layouts before construction starts. Two of them deserve attention during the first site visit.
01 / PERMEABLE PAVEMENT
Permeable Pavers Still Count at Stormwater Thresholds
Maple Valley treats permeable pavement as impervious when it applies the Surface Water Design Manual's thresholds and exemptions. Permeable pavers can still help with water movement, but they don't remove the project from those threshold calculations.
02 / PROTECTED TREES
Plat and Development Conditions Can Protect Smaller Trees
A landmark tree needs a permit before removal. Trees planted or retained under an approved plan, tree protection area or other development condition can also require a permit regardless of their current size.
55% to 80%
Residential impervious-surface caps vary by zoning. R-4 is 55%, R-6 is 70%, R-8 is 75% and R-12 through R-24 are 80%.
2,000 sq. ft.
Flow-control BMP requirements can begin at 2,000 square feet of new plus replaced impervious surface.
7,000 sq. ft.
The same flow-control requirement can apply at 7,000 square feet of land-disturbing activity.
5,000 sq. ft.
Projects at 5,000 square feet of new plus replaced impervious surface can require flow-control facilities.
Requirements can change by parcel, zoning, critical areas and project scope. Current city requirements should be confirmed during project planning.
