Arroyo Vista

277 addresses sit inside the 78.8 acres the city draws for Arroyo Vista on its HOA Local register. They sit on sixteen streets, San Bonifacio, San Patricio, Santa Teresa and San Mateo among them. The published boundary follows lot lines and leaves the street rights of way outside it, so no centerline falls inside. The county parcel record inside the boundary is 317 parcels, predominantly detached single family houses. The median lot the county records here is 0.13 acres and 57 feet wide. The city general plan gives 39.5 of those acres a low density residential designation. The zoning layer puts 39.0 acres in the RL-5000 zone and 33.3 in OS. Mail here carries the 92688 zip code and a Rancho Santa Margarita postal city.

The city general plan books 8.4 acres of parkland to Arroyo Vista at one site, Arroyo Vista Park. The city amenity table lists organized sports fields, a baseball diamond, a children's play area, picnic tables, a swimming pool, tennis courts and volleyball courts at Arroyo Vista Park. 43.9 acres are rated Very High on the 2025 state fire hazard severity map the city publishes. The city assigns the ground to evacuation zone RSM07, which it describes as SFR, HOA Park and Pools. Water comes from the Santa Margarita Water District and trash is collected Thursday by CR&R. All of it lies in Capistrano Unified, which feeds Arroyo Vista Elementary and Tesoro High.

Arroyo Vista covers a long stretch of the old Plano Trabuco, the tableland that formed the upper part of the O'Neill ranch. Flood and O'Neill bought the ranchos in 1882, the family kept the Orange County half when the holdings were split in 1940, and in 1942 the federal government took the southern portion for Camp Pendleton, which left about 52,000 acres up here in cattle. That is why a neighborhood built in the late 1980s can still look out over open hillside on one side and a full grid of houses on the other.

This is one of the larger single family pockets on the plain, laid out at the end of the 1980s as Rancho Santa Margarita filled in behind its 1986 opening. Its streets are named for saints, San Bonifacio, San Patricio, Santa Teresa, San Mateo, San Ricardo, San Tomas and San Anselmo among them, which is the same mission theme the developers used across this quarter of the city. The elementary school this neighborhood feeds carries the Arroyo Vista name too, so for most families here the neighborhood and the school are one word.
