Minor changes to or deviations from an approved master plan may be approved by the majority vote of a Committee, consisting of the Director of Community Development, the member of the Planning Commission and the member of City Council representing the Ward or Wards in cases where the property is located in more than one Ward in which the PUD is located (the "Committee"), without going through the procedure set forth in this section, if conditions arise which merit such changes or deviations. The request for changes or deviations must be supported by graphic and other information necessary for appropriate evaluation of the request. For the purpose of this section, minor changes or deviations refer to changes of location and design of buildings, other structures, streets, parking, recreation facilities, open space, landscaping or similar details which do not materially alter the character or concept of the approved master plan.
