Yard Anatomy
See what your landscape is made of.
Three interactive cross-sections built from 35+ years of coastal design-build work — the systems above and below grade, and how they earn (or lose) their keep.
The anatomy
What a coastal landscape is made of.
Everything you see in a finished garden depends on what you can't see. Tap a numbered point to read what it does, how it fails, and when to call us versus grab a trowel.
Below-grade systems drawn schematically — tap a numbered point to inspect it.
01 — Hardscape & patio base
Patios, walkways, and walls are only as good as the compacted base beneath them — on coastal lots that means engineering for clay soil movement and moisture.
How it fails
Sunken or rocking pavers, cracked mortar joints, water pooling against the house.
One for the Bradley crew
Base prep is where hardscape lives or dies. Re-leveling a paver is easy; rebuilding a failed base under a finished patio is not.
02 — Irrigation mainline & valves
A pressurized mainline feeds zone valves; each zone matches plant water needs. Smart controllers adjust for coastal fog, rain, and season.
How it fails
One zone always wet, controller running during rain, a water bill that creeps up every summer.
Depends on the day
Swapping a drip emitter is a homeowner job. Valve manifolds, pressure problems, and system design belong with a licensed crew.
03 — Drainage & French drains
Perforated pipe in gravel intercepts water moving through soil and carries it away from foundations, slopes, and planting beds.
How it fails
Soggy lawn days after rain, efflorescence on walls, erosion channels cutting through beds.
One for the Bradley crew
Drainage is grading math. Getting the fall wrong moves the problem somewhere worse — usually toward the house.
04 — Root zone & soil health
Coastal North County soil ranges from sandy loam to heavy clay in a single lot. Amendments, mulch, and mycorrhizae make or break establishment.
How it fails
Plants that sulk for years, water sheeting off beds instead of soaking in, chlorotic yellow leaves.
Depends on the day
Mulching is a weekend job. Diagnosing why a bed never thrives usually takes a soil eye that has seen a thousand of them.
05 — Low-voltage lighting
A 12V transformer feeds buried cable runs to path, up, and moon lights. Good design layers light — it never floodlights the yard.
How it fails
Flickering fixtures at the end of a run (voltage drop), corroded coastal connections, glare instead of glow.
Depends on the day
Swapping a lamp is DIY. Designing scenes and sizing cable runs for a whole property is where the craft shows after dark.
06 — Slope & erosion control
Coastal slopes want deep-rooted, drought-tolerant cover, terracing or low walls, and drip irrigation — never spray — to stay put.
How it fails
Rills after the first winter storm, bare soil patches, a fence line that leans a little more each year.
One for the Bradley crew
Slope failures are expensive in the exact way well-built slopes are invisible. This is engineering wearing a garden costume.
07 — Trees & specimen canopy
Specimen trees anchor the design and put the rest of the garden in scale. Placement accounts for mature size, views, and salt wind.
How it fails
Roots lifting hardscape, limbs over the roof, a 'small' tree now blocking the ocean view.
One for the Bradley crew
Structural pruning in the first ten years decides the next fifty. Topping a mature tree is the one mistake you can't undo.
Hardscape cross-section
A patio is seven decisions deep.
Two patios can look identical the day they're finished. Ten years later, one is still dead-flat and one is a wave pool. The difference is everything below the pavers — tap each layer to see what it does and where cheap installs cut it.
Drawn to concept, not to scale — the proportions favor legibility.
Pavers / natural stone — 2.4–3.1 in
The only layer you see — concrete pavers, porphyry cobble, or natural flagstone, laid to pattern with tight, consistent joints.
Where cheap installs fail
Cheap installs spend the whole budget here so the surface looks great in photos — for the first year.
Polymeric jointing sand — Joint fill
Hardens between pavers to lock the surface, shed water, and keep weeds and ants out of the joints.
Where cheap installs fail
Skipped or replaced with loose play sand — joints wash out the first winter, then the weeds move in.
Bedding sand — 1 in, screeded
A thin, dead-level screed bed the pavers seat into. One inch — no more. It's a leveling course, not a foundation.
Where cheap installs fail
Piled thick to hide a lazy base job. Thick sand migrates, and the surface rolls like a wave within seasons.
Compacted Class II base — 4–8 in, compacted in lifts
Crushed miscellaneous base compacted in 2-inch lifts to 95%. This layer IS the patio — it carries every load and keeps the surface flat for decades.
Where cheap installs fail
The classic corner cut: half the depth, one pass with a hand tamper. Every sunken walkway you've seen started here.
Geotextile fabric — Separation layer
Keeps the engineered base from slowly pumping down into coastal clay when it saturates. Cheap insurance measured in decades.
Where cheap installs fail
Invisible, so it's the first thing left off the bid. On clay lots the base sinks into the subgrade within a few winters.
Compacted subgrade — Native soil, graded to fall
Native soil cut to grade with 1–2% fall away from the house, moisture-conditioned and compacted before anything goes on top.
Where cheap installs fail
Built on loose fill or graded flat (or worse, toward the house). No layer above can fix water running the wrong way.
Edge restraint — Perimeter
Concrete or spiked composite restraint that holds the field tight. Without it the outer courses creep and joints open up.
Where cheap installs fail
Left off entirely on budget jobs — the field spreads, joints widen, and the pattern unravels from the outside in.
Irrigation, traced
Follow the water.
Every drop takes the same trip: meter, backflow preventer, valve manifold — then one of three very different last steps. Switch the delivery type to see how the endgame changes what your landscape actually drinks.
The highlighted branch is the selected delivery type — the others stay plumbed but idle.
Drip / inline emitter
Water arrives at the root zone drop by drop — nothing atomizes into coastal wind, nothing runs off clay. This is what we install in virtually every bed.
Best for: Planting beds, slopes, trees, veggie gardens
Rotary nozzle
Slow-rotating streams that soak in rather than fog away. Where a lawn stays in the design, high-efficiency rotary nozzles replace old spray heads.
Best for: Larger turf areas that earn their keep
Conventional spray
Fixed heads that mist — and in Encinitas afternoon wind, a third of that mist never lands on the yard. Prime candidate for a retrofit.
Best for: Legacy systems (we mostly retire these)
Most coastal systems we audit are a mix of all three — usually with spray heads watering sidewalks. An irrigation tune-up pays for itself in a summer or two.
