The only issue of major concern during the discussion was regarding the stability of the scenic Emerson Mine head frame ruin. It was mentioned that a heritage oak tree is starting to undermine the foundation of the ruin, and that part of a rock wall collapsed into the mine shaft last year. City residents fear that the grading project will further disrupt the ruin. City Manager Rob Duke said that he would pursue the matter, but stated that the city was in a “catch 22” with the issue of the heritage oak. He also stated that the developer had expressed unwillingness to shore the ruin without first capping the mine shaft concealed beneath it.
