Plenty of Santa Clara backyards have pools, and plenty of pool decks are tired. A pool deck in pavers has to stay cooler underfoot, offer decent traction when wet, and drain away from the pool coping. We pay attention to color choice and surface texture, and we plan how runoff leaves the deck so it doesn't flow back into the water.
Because the valley floor is flat, a French drain often belongs in the plan, either along the back fence, beside the house, or behind a pool deck. We use perforated pipe in washed rock, wrapped in fabric, with a steady fall to an outlet. On clay, a drain that can't discharge anywhere is just a slow pond, so the outlet gets sorted first.
Old orchard-era yards sometimes have large mature trees. We look at root zones before digging near them, since cutting major roots can hurt a tree and the property owner may need to check on any local tree rules first.
