The Authority shall be governed by and administered through a Board of Directors (the “Board”). The number of voting members of the full Board may not be less than 13, excluding vacancies, nor more than 25. The Board has full authority to increase or decrease its membership, within the limits specified in this subsection. Of the voting members of the Board:1 shall be appointed by the Mayor; 1 shall be a Councilmember appointed by the President of the City Council; and at least 3 shall be representatives selected from among various businesses, organizations, and residents in the District. At all times, at least ⅔ of the Board must be representatives of property owners subject to the tax imposed by this subtitle. These must be so designated by the Board and entered into the minutes of the Authority. Consistent with the encouragement of partnerships between the Authority and property owners exempt from the tax imposed by this subtitle, the Board is encouraged to consider representation of those partners on the Board. The terms of the members are staggered as required by the terms of the members first appointed. All powers of the Authority are exercised by and through the Board, unless delegated by the Board to 1 or more officers of the Board or to the Administrator. The Board may adopt bylaws, rules, and regulations as it considers necessary to carry out the powers of the Authority. However, these bylaws, rules, and regulations may not be inconsistent with the terms of this subtitle or of <cite data-doc="City of Baltimore, Md., Charter" data-path="II|§(63)">City Charter Article II, § (63)</cite>. All bylaws are subject to the approval of the Board of Estimates. The Board may establish its own procedures relating to the internal administration of the Authority, except as may be restricted by <cite data-doc="City of Baltimore, Md., Charter" data-path="II|§(63)">City Charter Article II, § (63)</cite> or this subtitle. The Board shall select from among its members individuals to serve as the chair, vice-chair, treasurer, and secretary of the Authority. These officers serve at the pleasure of the Board. The Board may delegate to these officers those responsibilities that the Board considers appropriate. Ord. 07-417 Ord. 15-433
