An acacia tree fell down on Carbonera Drive in April 2017, taking out a driveway pillar and Japanese maple for one homeowner.
The City of Santa Cruz removed it the same day.
But it turns out this was not the result of all the rains. Rather, the condos at Isbel Court have a leech field / septic system at the top of the steep hill, which pours down the hill and supersaturates it. This destabilizes the tree roots.
The Home Owner's association is looking into the problem.
