The way in is the 405 north to the 605 and the 605 north to South Street, 15 miles and about half an hour with a mixer behind, and the whole city sits within a few minutes of that ramp. Cerritos is in Los Angeles County, and permits go to the City of Cerritos Building Division at City Hall on Bloomfield Avenue. A change to the front of a house, the drive included, goes there as a drawing before it is cut, and the width at the curb is an encroachment permit through Public Works.
The tracts run in straight streets between Bloomfield Avenue, Carmenita Road and Studebaker Road, on the old dairy grid, with Los Cerritos Center and the Auto Square on the 605 side and the Civic Center in the middle. The lots are rectangular with a side yard wide enough for a truck, so a Cerritos job is rarely barrowed. The east edge is Coyote Creek and the Orange County line, the west is the San Gabriel River and the 605, and a yard drains to one or the other.
A drawing for the city has to show where the water goes, and that is a question a Cerritos lot deserves anyway. A room added at the back takes the roof out over what used to be lawn, so a downspout lands on the old patio, and a second story doubles the water off the same footprint. We set every new slab with a quarter inch of fall per foot away from the house and give the water a path to the street, and where an old patio sits below the new threshold we repour it to drain.
