Going to be a great pool - I haven't read each post in detail, but a note on one of the drawings for landscaping, I see Oleander - that is not good for dogs, one of the more poisonous plants for them. What I like in this part of the country are Azaleas and even better the newer Encore Azaleas - they are green year round and they are supposed to bloom 3 times a year - I get two blooms for sure and a couple of years I've had 3. They are hardy and make really nice plants. If you put good acidic soil in for them the will be almost maintenance free.
