If not included in your contract, and if you haven't done it yet, you need to start on your landscape plan. What type of plants? Irrigation needs, landscape lighting and if it will be DC or Solar. If DC lighting, you will need a power source for it. Where is the power source going to be and how difficult will it be to access it? (hint, add a spot for that to your pool sub panel).
Plan it down to the last tree, bush, flower, leaf and blade of grass and sprinkler head.
