The previous owner of my house in Florida planted a crepe myrtle tree right next to a CMU seawall and steps. It has a bunch of roots spreading through the whole backyard. To add a drainage pipes outlet and anchoring rod is located right under the tree. Upon checking historical aerial images it seems that the tree was planted around 10 years ago. It is beautiful when blooming but that's a terrible placement of that tree.

I am concerned that removing the tree might cause more damages if the roots already grown below or through the seawall.

Do these trees have invasive roots that could damage the seawall?

Does it actually help with stabilizing the wall and the soil or causes more harm?

Have the tree removed. There is no harm to the wall by removing the tree, but leaving it grow will result in the wall being compromised.

Treat the stump with a stump killing compound Use a product that is brushed on and not sprayed to prevent dispersing chemicals into the water.

The stump and roots will eventually rot. The soil is very sandy and drains water quickly. There is no need for additional drains and drainage pipes in the ground, so any root infiltration that has happened is moot.
