Sooo many great landscaping ideas for succulents here! To reduce your water bill, get rid of the lawn with weekly mowing and every day watering. Hardscape with bricks, cement pavers , broken concrete, or tile, but to avoid the heat island effect, add blocks of low growing groundcover succulents like Sedum, Crassula, or Echeverias for an outdoor "quilt" which reduces the heat island effect of pure hardscape and helps rain permeability.
