It is the intent of this chapter that a city planning commission be provided which will represent the concerns of diverse citizen groups, as well as the broad interests of the community as a whole; that membership of this commission provide balanced representation in terms of geographic, professional, neighborhood, and community interests; and that a wide range of expertise relating to the development of a healthy and well planned community be sought when establishing or altering the composition of the membership of the commission. Suggested interests, from which expertise might be selected, are as follows: banking, development, contracting, engineering, geology and seismology, law, ecology, the behavioral sciences, historical preservation, architecture and landscape architecture. It is not, however, intended that the composition of the commission be limited to professions, but rather, that it represent a cross section of the community. (Ord. 07-30 § 2)
