I beg to inform you that the sign erected at the above location is contrary to the regulations governing the issuance of the permit. I have therefore to request that you will kindly take immediate steps to rectify this matter by re-erecting the sign at least 11 feet above the M.C.R. and not projecting more than 3 feet beyond the building line.
