Tustin is the next city south of ours, so a crew leaves Orange on the 55, comes off at Irvine Boulevard and is on an Old Town street in a quarter of an hour. Permits are issued by the Building Division of the City of Tustin at City Hall on Centennial Way. Flatwork at grade in your own yard needs none. A wall over 4 feet, a footing under a cover and work in the parkway or the public walk are checked, and a street-facing change in Old Town answers to the Cultural Resource District too.
North of Irvine Boulevard the ground starts to rise toward Red Hill and Peters Canyon, and Tustin Ranch was built up there in the 1980s and 1990s on cut and fill pads, each under an association that reviews what shows from the street. A patio at the back of one of those lots often ends at the top of a graded slope, so the slab is pitched to a drain and out to the street, never over the edge. The association's approval goes in before the permit does, and we prepare both.
Tustin Legacy is the newest ground in the city. The Marine Corps air station closed in 1999, and its runways and aprons were broken out before the streets went in, so the fill under a new yard there was placed by a grader and is firm in the middle of a pad and looser near its edge. We probe it before we set a form. The lots are narrow, and most concrete goes in by barrow through a side gate rather than by chute from a mixer, which is a day the wider streets do not need.
