ma23peas,
I'm pretty sure you know that but the "very little" got my attention. Even if you have to bring in some fill, that is a better choice than water running towards the pool.
If you're on a slope and it cannot be helped, provide for an adequate "gutter" to carry the water away from the decking.
This caught my eye. As you establish the elevation for your pool, be sure absolutely no water can drain towards the pool or decking.rescape the yard so no drainage or very little would come towards pool
