For over 35 years, Lavish Gardens Landscape has transformed outdoor spaces across Northern California โ€” one masterpiece at a time.

From Rocklin to El Dorado Hills, our licensed and insured team brings meticulous craftsmanship to every property. We understand the local climate, soil, and lifestyle โ€” so every garden thrives where you live.

Sustainable ยท Water Management

Engineered for the
100-year storm.

As a core part of our Luxury Xeriscaping practice, this discipline is where the craft becomes specific โ€” the techniques, materials, and tolerances that separate generational work from passable work.

Most landscape failures โ€” settled patios, rotted decks, cracked walls, dying plants โ€” trace back to a single root cause: water in the wrong place.

We design drainage as a system before any other element goes in. The visible landscape rests on an invisible network of pipes, swales, and grade transitions.

Sacramento Valley storm events are intensifying. We size pipes and swales for current rainfall maxima, not 1980s data, and we daylight every line where possible.

The Craft

01

Calculated pipe sizing

Roof area + impervious surface = required capacity.

02

French drain & catch basin

Filter fabric, gravel chimney, NDS components.

03

Bioswales & dry creek

Naturalistic conveyance that doubles as garden feature.

Materials & Spec

The short list we trust.

NDS catch basins & grates Industrial-grade flow capacity
4โ€“6" SDR-35 PVC Solid and perforated
Mexican beach pebble Dry creek beds, decorative
Mirafi filter fabric Prevents pipe clogging

The Process

Four steps. A clear vision.

01

Storm modeling

Site contributions calculated; outlets identified.

02

Drainage design

Pipe network, catch basins, swale grades drawn.

03

Trench & install

Trenched lines, set basins, backfill in lifts.

04

Test & refine

Water-tested under flow, grades adjusted as needed.

Considerations

Questions worth asking.

Plants help โ€” they're not a substitute for engineered conveyance. Any large impervious surface, including roof, patio, or driveway, needs a designed outlet.

Almost entirely. Catch basins go beneath grates that match the surrounding hardscape, and dry creek beds become garden features in their own right.
