1.2 Greenfield Urban
Introduction
The precinct requires that subdivision and development occurs in a comprehensive and integrated manner by:
•requiring the preparation of a structure plan in accordance with the matters listed in Appendix 1
•restricting any urban subdivision, land use or development prior to the approval of a stormwater network discharge consent for the catchment
•restricting any urban subdivision, land use or development prior to the approval of a structure plan or which does not comply with the structure plan.

It is envisaged that future subdivision, land use and development consents will:
•comply with a structure plan 
•be in accordance with the approved discharge consent provisions
•not adversely impact on stormwater runoff, water quality, and avoids upstream or downstream flooding
•be staged according to the provision of infrastructure
•vest areas for open space (recreational and passive) and for stormwater management purposes.

Belmont-Pukekohe
The Belmont-Pukekohe sub-precinct comprises approximately 72 hectares and is located to the west of the Pukekohe Town Centre. The western edge of the precinct forms the western extent of the RUB.

The sub-precinct contains important natural (and ecological) features including the Whangapouri Stream, Robinson's Swamp and a number of scheduled trees.

The sub-precinct falls within the Whangapouri stormwater catchment area (which drains into the Pahurehure Inlet), and lies outside the existing approved urban stormwater catchment area for Pukekohe. One of the key issues to be addressed prior to, or in conjunction with the structure plan, is the management of stormwater for the Whangapouri catchment.

The provision of other infrastructure services (transport, water and wastewater) will also need to be addressed comprehensively through the structure planning process to ensure development is aligned with the infrastructure.

As the Belmont-Pukekohe area contains multiple landowners, structure planning will ensure that urban subdivision, land use and development occurs in a comprehensive manner.

Helensville
The Helensville sub-precinct is bounded in the north by Rautawhiri Road, to the east by Inland Road and to the west and south by steeper land. The precinct has a total area of approximately 46 hectares.

This sub-precinct is a key area for residential expansion within Helensville. Due to the physical characteristics of the site and topography, the precinct can accommodate a range of residential densities and housing forms. Residential growth should be focussed in close proximity to the Helensville town centre on the flatter areas to support a compact urban environment. The steeper areas in the west will be more constrained due to the topography and other physical characteristics.

As the sub-precinct has limited ground soakage, management of stormwater is important to avoid downstream issues particularly with the Awaroa Stream and floodplain. A structure plan approach will ensure that these issues are addressed and that any proposed development appropriately and comprehensively manages stormwater.

There is an indicative roading layout for the precinct shown on the Indicative Roads and Open Space overlay (refer to planning maps) which will need to be integrated into a structure plan. Structure planning will ensure a connected transport network can be achieved. There are constraints to the provision of water and wastewater servicing which will need to be addressed through the structure plan process, as these services are essential to any development in the sub-precinct.

The activities, controls and assessment criteria in the underlying zone and Auckland-wide rules apply unless otherwise specified below.

4. Assessment - Restricted discretionary activities
4.1 Matters of discretion
For the restricted discretionary subdivision activities in the Greenfield Urban precinct, the council will restrict its discretion to the following matters, in addition to the matters specified for the activity in the Auckland-wide - Subdivision rules.
1.The subdivision should:
a. comply with the approved structure plan
b. provide a mix of site sizes. Smaller sites should be located closer to public open space, community facilities and commercial centres

b.whether the element can be achieved by another means.
5. Assessment - Discretionary activities
5.1 Matters of discretion
While not limiting the exercise of its discretion, the council may consider the particular matters specified for the discretionary activities listed below.
