A flight of steps here is a piece of the lot's grading, not an ornament at the door. The Mission Viejo Company set houses above the street on one side of a road and below it on the other, so the front walk on half the streets climbs from the sidewalk to a sill well above it, and the side yard behind a pool home drops as far again to the deck. The flight is what makes that change of level walkable, and it is built from the rise, the run and the ground beside it, in that order.
Trevor Lindqvist founded Saddleback Mission Viejo Concrete in 2018 after 17 years on crews across south Orange County, and a hillside flight is the job he sets out himself, with a tape and a level, before anyone digs. The original walks here were often loose flights of precast blocks, or railroad-tie risers cut into the bank, and the bank has crept into them for forty years. He measures the total rise, divides it into equal risers, and only then decides where it turns.
Steps are built to the California Residential Code, which holds a riser to 7 and 3/4 inches at most, a tread to 10 inches at least, and every riser within 3/8 of an inch of the others, under a CSLB C-8 license with liability insurance on every job. Four risers or more take a handrail, and a front flight is what the association sees first, so its finish goes in with the estimate. The flight carries a written workmanship guarantee against defects in how it was built.
