(a) With respect to each sign identified in the sign inventory as non-conforming, the registered architect or professional engineer shall request confirmation of its non-conforming status from the Department based on the evidence submitted in the registration application. The Department shall review the evidence submitted and accept or deny the request within a reasonable period of time. A sign that has been identified as non-conforming on the initial registration application may remain erected unless and until the Department has issued a determination that it is not non-conforming. The registration of the OAC and remaining sign inventory shall continue unimpeded while such a determination is pending.
(b) The Department shall maintain a list of all signs that it accepts as non-conforming.
(c) The Department may withdraw its acceptance of a non-conforming sign upon discovering evidence that the sign was improperly considered, or should no longer be considered, a non-conforming sign, and upon such withdrawal and after notice to the OAC, the sign must be removed pursuant to the Zoning Resolution.
