Xeriscaping is a great way to get rid of some of your sprinklers. Some ideas are a play area and future raised garden box site. You’ll never again have to drag your trampoline back and forth when you mow. You can also convert existing sprinklers to drip lines for shrubs, garden boxes, etc. Utah is a desert and water can be an issue. I like curbing a pathway around the yard, leading to different areas like small patio with a trellis or koi pond or maybe a fire pit. If you use a good amount of fill and lay down plastic or weed barrier maintenance can be as easy as spraying weed killer when the weeds try to come up. Read up on round up and grass killers there not as bad as you might think.
