Sun Valley Landscape Design — Flood-Smart, Fire-Aware, Equestrian-Capable

Landscape Design Questions Homeowners Ask About Landscape Design in Sun Valley

Is my Sun Valley lot subject to defensible-space inspection?

If you're in the Stonehurst foothill corridor on the west side of 91352 — usually yes, annual LA County Fire inspection under PRC 4291. Most of the rest of 91352 is outside the VHFHSZ. We confirm against the CAL FIRE FHSZ viewer during the assessment.

Is my Sun Valley lot in a FEMA flood zone?

If you're on the Tujunga Wash side near Hansen Dam — possibly yes, in FEMA Zone A. We check the FEMA flood map service before design work. Flood-zone landscape needs engineered drainage routing — $4K-$10K above a standard landscape.

How much lawn can I keep under MWELO?

On a typical 5,500-7,500 sq ft Sun Valley lot, you can usually keep 300-600 sq ft of lawn as a focused use feature and still clear MWELO — provided the rest of the yard is low-water Mediterranean or California native. A 2,500 sq ft front lawn is not coming back.

What plants thrive in Sun Valley?

California natives: toyon, manzanita, ceanothus, Cleveland sage, white sage, California buckwheat, deer grass, California fuchsia, coast live oak, sycamore. Mediterranean: rosemary, lavender, olive, palo verde, crape myrtle, agave, aloe. All handle Sun Valley's 100-103°F July afternoons on minimal irrigation once established.

Can you coordinate with a Vinland equestrian use?

Yes. LA County Title 22 requires 35 feet between any habitable structure and an equestrian use. We design the landscape around the paddock, barn, and 35-foot buffer, place patio and outdoor kitchen on the non-equestrian side, and route irrigation to avoid the paddock waterline. About a fifth of our Sun Valley jobs are on Vinland equestrian lots.

What's the cheapest realistic Sun Valley landscape?

$35,000 — a 2,500-3,000 sq ft front-and-side landscape with drought-tolerant palette, decomposed-granite paths, drip irrigation, accent boulders, and LED low-voltage lighting on a Valley-floor lot outside the flood and fire zones. Below that, someone is skipping the MWELO documentation or downgrading the irrigation.

How long does a Sun Valley landscape take?

Entry-tier front-only: 3-5 weeks. Mid-tier full-property: 6-11 weeks. Full build with outdoor kitchen and structural work: 12-17 weeks. Flood-zone or VHFHSZ documentation adds 1-2 weeks at the front. We schedule planting for November-February cool season whenever possible.
