4 Modern/Minimalist Design Ideas for Riverside

The California Modern Front Yard

$12–22/sqft

A Riverside contemporary home replaces its lawn with a bold California modern composition: large-format warm grey concrete pavers form the driveway and entry plaza while the planted areas hold sweeping masses of deer grass and blue oat grass with a single multi-trunk specimen olive tree as the focal anchor. Black steel edging defines the geometry while two rounded shapes of ‘Shoshone’ westringia provide evergreen structure flanking the entry. Decomposed granite in warm tan fills the remaining ground plane. A smart drip controller maintains the planting with 70% less water than the former lawn, and the RPU turf removal rebate offsets a significant share of installation cost.

Plants: Olive tree, deer grass, blue oat grass, westringia, autumn sage

Materials: Large-format concrete pavers, warm tan DG, black steel edging, drip irrigation

Perfect for: Riverside contemporary homes wanting a drought-tolerant modern front yard that eliminates lawn maintenance and qualifies for RPU’s $4/sqft turf removal rebate

The Backyard Patio with Pergola and Fire Feature

$18–35/sqft

A 450 sqft large-format paver patio with a steel pergola creates the outdoor room for this Riverside backyard. A square concrete gas fire pit serves as the focal centerpiece while a high-quality outdoor sectional completes the living arrangement. The perimeter planting uses bold masses of Karl Foerster grass, agave, and deer grass for year-round structure and privacy. A specimen blue palo verde tree provides filtered shade and the brilliant yellow spring bloom that is the signature of Inland Empire modern gardens. LED path lighting creates the evening atmosphere that Riverside’s outstanding October–April outdoor season rewards most.

Plants: Blue palo verde, Karl Foerster grass, agave, deer grass, autumn sage

Materials: Large-format concrete pavers, steel pergola, concrete fire pit, LED path lighting

Perfect for: Riverside backyards wanting a year-round outdoor living room with a fire feature and contemporary plant masses that eliminate turf entirely

The Modern Pool and Deck

$22–42/sqft

A rectangular dark-plaster pool with clean geometric lines sits at the center of this Riverside backyard. Cool-coat sealed concrete in large format covers the surrounding deck while a horizontal-slat cedar fence screens on three sides. Specimen agave americana anchor the pool corners while deer grass and Mexican feather grass fill the fence-line beds. An aluminum patio cover on the west side of the deck provides the critical afternoon shade that Riverside’s 105°F+ summers require. Underwater LED lighting and a poolside fire bowl extend the season through Riverside’s mild October–April outdoor period. A built-in outdoor kitchen completes the entertainment infrastructure.

Plants: Agave americana, deer grass, Mexican feather grass, blue palo verde

Materials: Dark-plaster rectangular pool, cool-coat concrete deck, aluminum patio cover, horizontal cedar fence, outdoor kitchen

Perfect for: Riverside homeowners wanting a sleek modern pool backyard optimized for the Inland Empire’s long outdoor season with proper afternoon shade for summer usability

The Tiered Modern Garden with Boulders

$20–40/sqft

A sloped Riverside lot is terraced with poured concrete retaining walls into two landscape levels. The upper level holds a clean concrete patio with a gas fire feature and outdoor dining furniture. The lower garden uses large-scale native grass masses — giant feather grass and deer grass in bold sweeps — with Inland Empire granite boulders anchoring the transitions between levels. Desert willow trees at the fence line provide privacy and seasonal lavender bloom May–September. The entire composition frames the borrowed landscape of Riverside’s surrounding hills and creates a genuinely Inland Empire modern garden.

Plants: Giant feather grass, deer grass, desert willow, agave, autumn sage

Materials: Poured concrete retaining walls, poured concrete patio, gas fire feature, Inland Empire granite boulders

Perfect for: Sloped Riverside properties wanting a terraced modern landscape that engages the Inland Empire’s hill backdrop with authentic regional plant character

Design Tips for Riverside (Zone 9b)

• Apply for RPU’s $4/sqft turf removal rebate BEFORE removing grass — the pre-approval requirement means no rebate after-the-fact, and the $3,200–$4,000 cash back for a standard front yard is one of the best landscape ROIs available in Inland Empire
• Apply cool-coat sealer to ALL concrete and paver surfaces before the first summer — Riverside’s 105°F+ summer sun heats untreated concrete to 150°F, making pool decks and patios unusable without heat-reflective surface treatment
• Install an aluminum patio cover rather than a wood pergola in Riverside — the combination of summer heat, Santa Ana wind season, and occasional high winds makes aluminum the more durable and maintenance-free structural choice
• Use warm tan DG rather than grey for Riverside modern landscapes — the warm tones harmonize with the tan-and-rust color of Inland Empire granite boulders and the surrounding chaparral landscape; grey DG looks institutional in this context
• Plant deer grass in masses of 5–9 plants as your primary ornamental grass — it’s the California native most adapted to Riverside’s chaparral-desert interface, handles extreme heat natively, and its fountain form reads as graceful in both contemporary and naturalistic compositions
• Orient your patio and outdoor kitchen to the east side of the yard — Riverside’s brutal west-southwest afternoon sun from 1–7 PM is the dominant summer challenge, and east-facing shade structures receive natural morning sun and comfortable afternoon shade during peak heat
