This is the section that separates Norco landscaping from every other city in the Inland Empire. In a town where 81.1% of residents own their homes and most properties back up to horse trails, the wrong ornamental plant is not a design mistake, it is a veterinary emergency.
Oleander is the number-one killer. It is planted as hedging across Southern California because it is drought-tolerant, evergreen, and fast-growing. It is also lethal: 30 to 40 leaves can kill an adult horse. Every part of the plant is toxic, leaves, flowers, bark, roots, even the smoke from burning trimmings. Horses do not have to eat it deliberately. Clippings blown into a paddock, a branch hanging over a fence line, dried leaves mixed into hay, all documented causes of death.
Yew kills in a single mouthful. Four ounces of needles, roughly one bite, contains enough taxine to stop a horse’s heart. Red maple is insidious: the fresh leaves are mildly toxic, but wilted or dried leaves destroy red blood cells and cause fatal anemia. A single storm-downed branch left in a pasture has killed horses. Foxglove contains cardiac glycosides. Sago palm causes liver failure. Every Prunus species, cherry, plum, peach, releases cyanide from wilted leaves.
Also toxic in quantity: privet, oak acorns, nightshade, jimsonweed, castor bean, ragwort, boxwood, lantana, lilies, daffodils, delphinium, and milkweed.
Every Norco landscape we design starts with a horse-safe plant palette. These species are non-toxic, drought-adapted for Zone 9b–10a, and proven performers on Norco’s sandy loam soils:
Fences do not always stop a curious horse from reaching over. We plant toxic-free buffer zones along every fence line, trail easement, and property boundary. Read our xeriscaping guide for more drought-adapted species that work on Norco properties.
Most landscaping companies treat Norco like any other Inland Empire suburb. They show up, quote a patio, and have no idea that the hedge they are about to plant will poison the neighbor’s horses. They do not know what an AKO zone is. They have never graded an arena. They do not understand why you need a 6-foot solid fence within 35 feet of an adjacent residence when you are keeping animals.
We do. Monarch has been a licensed C-27 contractor (CSLB #957605) since 2009. We work on large lots, the kind of properties Norco is built around, and we understand that a Norco project means working around horse infrastructure, trail easements, and animal schedules. Our crews know to keep gates closed, secure materials away from curious animals, and clean up completely so there is nothing left for a horse to step on or eat.
From Norco Farms ranches to Norco Hills estates, we bring horse-safe plant knowledge, proper grading technique, and the kind of project management that accounts for the realities of equestrian property life. Learn about Monarch.

Hardscape Details →“We had no idea our oleander hedge was toxic to horses until a neighbor mentioned it. Called Monarch and they pulled the entire hedge and replaced it with rosemary and bougainvillea in three days. They also put in turf around the front of the house and ran French drains along the paddock fence line, the mud problem we had every winter is completely gone. The crew worked around our three horses without any issues. Gates stayed closed, nothing left on the ground. They clearly have done this before.”

“Had Monarch pour a barn pad and wash rack, build a retaining wall on the hillside behind the barn, and install drought-tolerant planting beds along the driveway. They understood what we needed from the first walkthrough, drainage for the wash rack, non-slip finish on the pad, and plants that would not make our horses sick. The retaining wall opened up usable space we did not know we had. Great crew, clean jobsite, and they finished ahead of schedule.”

Ridge Ranch / Norco Hills
Population 25,400 across 14.1 square miles. Every neighborhood in the Equestrian Historic District, from working ranches to hillside estates.
The historic core of Horsetown USA. Midcentury ranch homes and farmhouses on half-acre to one-acre+ lots. The 6th Street commercial corridor with rodeo cafes, saloon-style bars, and hitching posts at businesses. Classic horse-property lots where the trail system was born. Median around $810K. This is where you see horses in the McDonald’s drive-through. Hanford sandy loam soils drain well, ideal for paddock grading and pasture drainage. Common projects: oleander removal, paddock drainage, front yard turf replacement, block wall corrals, concrete barn pads.
Southern Norco at higher elevation (~735 ft) with newer 1990s–2000s Spanish and Mediterranean construction. Median home price around $1,340,000, the most expensive neighborhood in Norco. Larger homes (3,000–5,000+ sqft) on graded hillside lots. Some HOAs present. Ramona fine sandy loam with clay subsoil at 2–3 feet requires careful drainage engineering for arenas and paddocks. Common projects: retaining walls, hillside terracing, patio covers, outdoor kitchens, landscape lighting, large-lot irrigation systems.
Adjacent to Norco Hills with large 4–5+ bedroom homes, many built in the early 2000s on hillside lots. Modern construction with bigger garages for horse trailers and RVs.

The most dangerous plant on Norco horse properties is oleander, just 30 to 40 leaves can kill an adult horse, and it is one of the most common hedging plants in Southern California. Yew is lethal in a single mouthful (4 ounces of needles). Red maple kills through wilted or dried leaves that destroy red blood cells. Foxglove contains cardiac glycosides. Sago palm causes liver failure. All Prunus species (cherry, plum, peach) release cyanide from wilted leaves. Additional toxic plants include privet, nightshade, jimsonweed, castor bean, ragwort, boxwood, lantana, lilies, daffodils, delphinium, and milkweed. Safe alternatives: rosemary, lavender, sage, manzanita, ceanothus, California fuchsia, bougainvillea, crape myrtle, Bermuda grass, mesquite, desert willow, and palo verde. Every Norco landscape we design starts with horse safety.
Yes. Norco’s dominant Hanford sandy loam provides an excellent natural base for arena footing, it drains fast and compacts evenly. We grade arenas and paddocks with proper crown (1–2% slope center to perimeter) and install French drain systems along fence lines. For properties on Ramona fine sandy loam, common in Norco Hills, the clay subsoil at 2–3 feet depth can create a perched water table, requiring subsurface drainage trenched below the clay layer before grading. We also build DG-surfaced turnout areas, concrete wash racks with trench drains, and dust-control systems for arena use during Santa Ana wind events. Learn more about drainage solutions.
Most Norco residential properties in the 6,000-property Equestrian Historic District are adjacent to a Pedestrian-Equestrian (P-E) trail. The city maintains trail fencing, but your landscape must respect the trail corridor: no horse-toxic plants near fence lines where horses can reach over, no irrigation overspray onto trail surfaces, and no lighting that could blind riders. Norco’s municipal code also requires all landscaping to maintain a “rural, informal, traditional, rustic, low-profile and equestrian oriented” character. We design trail-side landscapes that work with these requirements while improving property value. Schedule a trail-side design consultation.
Yes, in non-horse areas like front yards, play areas, pool surrounds, and entertaining spaces. We do not recommend turf in paddocks or pastures because turf fibers compact under hoof traffic and infill material can cause GI issues if horses ingest it. For the human zones of your property, turf saves significant water on Norco’s half-acre+ lots. Rebates start at the $2 per square foot SoCal Water$mart base for residential lawn replacement with planting or rockscape, so confirm any Western Water add-on and current terms with your provider). Smart controller rebates up to $300 are also available. See our artificial turf cost guide for full pricing.
The Animal-Keeping Overlay (AKO) zone designates properties for keeping horses and livestock. Number of horses is based on lot size: 1 horse for 10,001–12,500 sqft, 2 for 12,501–15,000 sqft, 3 for 15,001–17,500 sqft, 4 for 17,501–20,000 sqft, and 5 for 20,001–25,000 sqft. Each adult animal requires 500 sqft of flat usable area. Animals must be 35 feet from an adjacent residence unless separated by a 6-foot solid fence. AKO properties must be adjacent to a horse trail. These rules directly affect landscape layout, we design around animal areas, setback fencing requirements, and trail access while maximizing usable outdoor living space for the homeowner.
Yes. We serve every Norco neighborhood, from the working ranches and classic half-acre horse lots of Norco Farms and Old Town (median ~$810K) to the $1.34M hillside estates in Norco Hills and Ridge Ranch. We also work in Hidden Valley, the River Road / Santa Ana River corridor, and Norco West. Our crews understand horse property realities: safe plant selection, arena grading, paddock drainage, barn pad concrete, block wall corrals, trail-adjacent landscaping, and large-lot irrigation systems.
