I think the letter to the encroachers should indicate to them that they have erected a fence on your property and that you plan to "take possession" of the fence and plan on removing it as well as the additional stored property they have given you and then set a time period during which they can chose to move it to their side of the property line or lose it all. Note in the letter that they may be billed for the removal work as they engaged in this on your property with out your permission. Send a copy of that letter to all the HOA board members as that fence is on your property and i would surmise that means you are in violation of the HOA rules despite the fact that you didnt do it. At the end of the waiting period get an attorney involved if no action is taken by either.
