Douglas County takes about sixteen inches of rain in a year, and much of it arrives in July as a thunderhead that piles up over the Rampart Range and empties itself in twenty minutes. Conserva Irrigation of Douglas County keeps lawns through the long dry stretches between those storms, mowing on a schedule the grass can actually carry. There is a real satisfaction in a yard that still looks intended in August, trimmed at the fence line, edged at the drive, holding its color while the open ground beyond goes to straw. The routes run out of Castle Pines and across the county, from the pine ridges down into the grasslands. Afternoon light here is enormous, and it shows every line you leave behind.
