D.C. Mun. Regs. tit. 10, r. 10-C210
An applicant may submit a written amendment of a filed application at any time before notice of the public hearing.
An applicant may submit a written request to withdraw a filed application at any time. The filing fee is not refundable and the staff shall not return the application materials upon withdrawal.
Before the staff accepts a withdrawal, the Chairperson of the Board may adopt the application by substituting the Board as the applicant for designation.
Within ten (10) days of accepting an amendment or withdrawal, the staff shall provide notice of the amendment or withdrawal in the same manner as provided for a newly filed application in § 207.2. If an amendment is to change the boundaries of a proposed historic district, the staff is not required to send notice of the amendment to owners of property outside the area of the amendment.
If an application is withdrawn, the staff shall not accept another application to designate the same historic landmark or historic district until twelve (12) months after the date of withdrawal. The staff shall determine whether a new application is the same as a withdrawn application.
Upon receipt of any subsequent request to withdraw the refiled application, the Board shall adopt the application by substituting itself as the applicant, and shall proceed to a hearing as provided in this chapter.
