Who is responsible for the fence damage?

[Mario Essig]

Who is responsible for the fence damage caused by a severe storm where:

Usually, when an "inside" side of the fence (with the horizontal 2x4 bars across the fence) is facing the owner in the owner's yard, the owner is responsible for the repairs.

The situation:
The "inside" of the fence (with the horizontal 2x4 bars across the fence) is facing the easement (which acts as a storm drain for flood control) in a HOA neighborhood. If the HOA is responsible for the easement, is it also responsible for the fence as well?

Let me know as I, an owner, and a neighbor are victims in this situation.
