Whenever acting on a development application for commercial uses where installation or modification by any sign is proposed, the Planning Board or Zoning Board of Adjustment, as the case may be, shall refer the application to the Sign and Facade Committee of the Downtown Development Commission for review and recommendation prior to approving or denying any application for preliminary approval. If located in the Historic District, the application shall also be referred to the Historic Preservation Commission for review and recommendation. Upon receipt of any development application for commercial use which proposes the installation or modification of any sign, the Secretary of the Board hearing the application shall forward one complete copy of the application to the Sign and Facade Committee and, when appropriate, to the Historic Preservation Commission. The Sign and Facade Committee and, when appropriate, the Historic Preservation Commission shall review the applicant's Master Signage Plan and submit recommendations to the reviewing board within 15 days after receipt of a copy of the application.
