I just saw this ! We live in Huntington Beach. We have one of those tall skinny houses downtown. We used artificial turf in the side yard area between the house and the fence. We absolutely love it. We went middle of the road on the product. Not the cheapest, nor the most expensive. We had them put it in so that it was Pet ready. They lay a layer of granite down and then sand (I think) then the weed prevention fabric, more sand (maybe, I am guessing the sand stuff), and then the turf. It helps with the pee drainage. We wash it down and it's perfect ! My husband also went to Home Depot and bought a plastic rake. There was an area where the turf was laying down a bit. He raked the stuff right back up and it was great. Kind like the old shag carpet trick in the 70's...snicker. We used a local francised company called Hunny Do Artifical Grass.
I say get a couple of bids too. The pricing can be all over the place. Be explicit about needing it put in Pet Ready too. Good Luck !
