    These are the classic symptoms of Phytopthora rot. This is usually associated with poor draining or saturated soils. There is a treatment that you can try, but there are no guarantees, unfortunately.

    I can't tell from the photo if it is dead, but dead branches can be removed. You may want to get a soil test to see if some micronutrients are low. This information should help:

    This is damage from overwatering. They do need time to dry out several inches into the soil between watering, or roots start to suffocate. I would try and find the right balance to water only when you do not get rain, or it is dry. At most, it will need water once per week.

    It is hard to say, exactly, what is going on without photos. I could take a guess at a few things that will likely be the cause. It has been pretty hot this year. Heat stress seems to be affecting many plants and trees. Keep the tree watered but not waterlogged. Soil that is too wet will cause this, as well. It can also invite disease.

    Just give it proper care, and as your landscaper mentioned, I would leave it on.

    Some trunk flaring is normal at the base of palms. There could be some rot going on after being inundated with flood water, though. The spots on green areas could be fungal spots and usually do not need treatment. I suggest having an arborist look at the trunk of your tree for advice. The tree is a beautiful specimen and I'd hate for you to lose it.
