Amends the membership of the Mooresville Travel and Tourism Authority (Authority), set by SL 1991-296, as amended. Modifies current requirements to include one member rather than two representing the Mooresville-South Iredell Chamber of Commerce, and three rather than two members representing the motel or travel and tourism industry. Adds the following members: one member representing sites and attractions that increase the use of lodging, meeting, or convention facilities in the area or attract tourists or business travelers to the area, and one member appointed by the Mooresville Town Board (Town Board). Specifies that the Town Board must designate a voting member as chair (was, a member). Authorizes the Town Board to amend the resolution creating the Authority so long as the amendments are consistent with the act. Regarding the Authority’s directive to adopt rules of procedure to govern its meetings, adds a new requirement for the rules of procedure to include the rules of membership and attendance that pertain to other boards and committees appointed by the Town Board which are consistent with the act.
