Mid-morning in California Heights the gray finally slides off the rooftops and the Spanish bungalows get their color back. CGW Landscaping is usually a few houses in by then — small square lawns mowed, the edger run down the driveway line, the low hedge across the front trimmed even with the porch rail. Weeds come out of the parkway before they can go to seed, and the cuttings ride out in the truck. Through the long dry half of the year the deck goes up a notch so the grass can shade its own roots. Every yard on the block gets the same treatment, corner lot or halfway down.
