Quarter Horse

Quarter Horse covers 230.8 acres and holds 242 addresses on 250 parcels, at a median lot of 0.466 acres, the third largest of the twenty-seven residential zones the city draws. Zoning is 175.5 acres Residential Estate and 32.4 acres Planned Development, and the assessor land use code marks 247 of the 250 parcels a single family residence. Nineteen named streets carry 4.1 miles of centerline with a single private segment. The city flags 238 of the 242 addresses as being in a homeowners association.

The community is built around riding. The Quarter Horse Staging Area covers 3.4 acres at 3906 1/2 Quarter Horse Drive and the city records it as equestrian staging, 2.94 miles of earthen trail run inside the boundary, and the city's point layer marks twelve trail entry points along with a hitching post, a water trough, a restroom and three scenic viewpoints. Every street name is a horse breed or a racing term: Belgian, Breton, Cleveland Bay, Clydesdale, Connemara, Dapple Gray, Falabella, Jutland, Lipizzan, Morgan, Oldenburg, Paso Fino, Red Roan, Shetland, Welsh Pony, Trotter, Steeplechase and Winners Circle. The 2025 fire hazard severity layer rates 195.3 acres Very High, the city flags 135 addresses as high fire severity and 125 as carrying a fuel modification requirement, and the state landslide zone layer covers 48.2 acres.

Every street in Quarter Horse is a horse. Belgian Lane, Breton Lane, Cleveland Bay Lane, Connemara Court, Falabella Lane, Jutland Lane, Lipizzan Lane, Morgan Court, Oldenburg Lane, Paso Fino Way, Shetland Lane and Welsh Pony Lane are breeds, drawn from Belgium, Brittany, Yorkshire, Ireland, Argentina, Denmark, Austria, New England, Germany, the Caribbean and Britain. Dapple Gray Lane and Red Roan Lane are coat colors rather than breeds, and Trotter Lane, Steeplechase Way and Winners Circle describe what happens once the horse is saddled.

The theme is not decoration. Yorba Linda calls itself the Land of Gracious Living and backs that with a working riding network rather than a slogan: the Quarter Horse Staging Area, 3.4 acres of it, sits inside this community, and the Quarter Horse Trail is part of nearly three miles of trail threading 242 homes across 230 acres. One of those trail segments is attributed to Chino Hills State Park, and 3.7 acres of the park itself fall inside the boundary line.
