Overview
About Box Canyon
Box Canyon covers 96.1 acres and holds 375 addresses on 109 parcels, at a median lot of 0.125 acres. The gap between the two counts is the housing type: 248 of the addresses carry a unit designator, and the whole polygon is zoned Planned Development under the city's district 16, with a general plan designation of R-High on 108 of the parcels. Nine named streets run 2.51 miles inside the boundary, and 61 of the 109 centerline segments are recorded private. Box Canyon Park sits on 9.7 acres at 23400 Foxtail Drive, and the city's facility record lists a playground, restrooms, a basketball court, a pickleball court and sheltered picnic areas. Placentia-Yorba Linda Unified serves the polygon through Yorba Linda High and the Travis Ranch middle school area.
Every acre here carries the top fire rating: the 2025 fire hazard severity layer rates all 96.1 acres of the boundary Very High. The city flags every one of the 375 addresses as high fire severity, and 272 of them carry a fuel modification requirement, the highest count of any zone the city draws. An Alquist-Priolo earthquake fault zone crosses 52.1 acres, the state liquefaction layer covers 35.4 acres and the landslide layer 33.1. Of the 375 addresses, 270 are flagged as sitting in a homeowners association, and 0.96 miles of earthen trail run inside the boundary on segments the city attributes to its landscape and maintenance district.

How Box Canyon was built
A box canyon is one closed at the far end, and the name is a plain description of the ground. This is the eastern edge of Yorba Linda, land that John Bixby bought from Bernardo Yorba's widow in 1878 and called Rancho Santa Ana. He ran cattle and sheep on it, and his daughter Susanna Bixby Bryant inherited the ranch after his death in 1891 and worked it for the next fifty five years.
The streets stay with the canyon: Box Canyon Court, Silver Canyon Road, Twilight Canyon Road, Sleeping Oak Drive, Woodland Avenue, Foxtail Drive, Lotus Avenue and Windy Circle. Box Canyon Park covers 9.7 acres inside the boundary with a playground, restrooms, a basketball court and pickleball courts, and just under a mile of city trail runs through, connecting into the network that reaches Chino Hills State Park, 1.9 acres of which fall inside this boundary.
