A designation is a provision in the Unitary Plan (district plan section) which gives effect to a notice of requirement for a public work or project by a requiring authority. A requiring authority is a Minister of the Crown, local authority or approved network utility operator, and a public work or project could include a school, police station, road, park, transmissions lines, airport or an infrastructure system. A notice of requirement is essentially an application for a proposed designation, not to dissimilar to an application for resource consent except that it specifically applies to designations under Part 8 of the RMA. It includes information about the proposed designation including among other things the description of the proposed public work or project by a requiring authority and any conditions or restrictions that might apply to the designation.A designation can:- Enable the use of land for a public work or infrastructure;- Restrict land, water, subsoil, or airspace where this is necessary for the safe or efficient functioning or operation of a public work or infrastructure; and- Require written approval of the requiring authority responsible for the designation before a third party can undertake and activity within the designation.Designations in the Unitary plan include existing designations rolled over from previous district plans into the Unitary Plan (wither “without modification” or “with modification”) and any new notices of requirement for a designation lodged with Auckland Council. Note that new notices of requirement for new designations are not shown in the draft Unitary Plan.
