Stanton is one of the densest cities in Orange County, 38,000 people on 3 square miles, and its lots are paved nearly to the fence. On ground this flat, a slab with no fall is a pond after one storm.
The houses are 1950s and 1960s tracts on small lots, and over 70 years the yards have been paved piece by piece, a patio here, a side path there, a parking pad where the lawn was, each poured flat and each by a different hand. The result is a lot with nowhere for rain to go. It pools against the house, runs under the fence to the neighbor, or sits on the slab and lifts the paint off the stucco. Add the mobile home parks and the townhome courts, where paving is shared, and grade is all.
So we start with a level, not a shovel. Every slab we pour in Stanton is set to fall a quarter inch per foot toward the street, a drain or a planter that can take it, and where a yard is enclosed on four sides we put a drain through the wall or a channel across the gate. The slab itself is 4 inches on 4 inches of compacted base with steel through it, jointed every 10 feet the day it is poured, and doweled into whatever old concrete it meets so the two do not step apart.
