About Environmental Planning Policies
Planning and development in NSW is carried out under the Environmental Planning & Assessment Act 1979.
As well as development assessment provisions, the Act also provides for the making of Environmental Planning Instruments, which are legal documents that regulate land use and development. These planning instruments are State Environmental Planning Policies (SEPPs) which are administered by the State Government, and Local Environment Plans (LEPs) which are administered by local Councils.
The Act also provides for public participation in planning decisions, amongst various other provisions.
A list of SEPPs and Deemed SEPPs (formerly Regional Environmental Plans) is provided in the NSW Planning Portal.
