Should the County and each of its ten cities establish growth boundaries preserving farmland, open space and scenic vistas by: (1) adopting by ordinance six existing and five proposed greenbelts and preventing uses incompatible with commercial agriculture; (2) prohibiting changes to external community boundaries unless approved by voters, including amendments no more than once every ten years; and (3) forming an Open Space/Agriculture Conservation District to receive public/private funds to acquire open space lands and farmland?
