This dataset comprises mapping associated with the State Planning Policy 2.4 Basic Raw Materials (BRM). Extraction Sites comprise all commercial extraction areas for BRM and those BRM quarries used by government for infrastructure. Extraction Sites include operating, approved and proposed commercial (extractive) industries under the Planning and Development Act 2005, the Local Government Act 1995, the Mining Act 1978 or a combination of these legislations. They may occur wholly or partly within or outside of Significant Geological Supplies areas. Where they occur outside of Significant Geological Supplies they provide important local supplies and in some cases provide for a specific market niche over the short to medium term. Currently, this dataset only shows those Extraction Sites that lie within the Perth and Peel Regions and that were identified by an extensive interagency BRM planning process, which included public consultation in 2015 and 2016. Within the Perth and Peel Regions, Extraction Sites include those that have Prior State Environment Minister approval. For practical reasons, it is not intended for this mapping to include all Extraction Sites, as these are administered by different agencies and in some cases can change within a short timeframe. However, the intent is for the State Planning Policy 2.4 to be applied to all Extraction Sites irrespective of whether they are shown in this mapping.

This dataset comprises mapping associated with the State Planning Policy 2.4 Basic Raw Materials (BRM). The Local government areas shown are those for which Significant Geological Supplies mapping has been completed to date. Many regional local government areas will not warrant the identification of Significant Geological Supplies as they do not experience the competing land use pressures associated with high growth areas nor the associated high demand for BRM.

This dataset comprises mapping associated with the State Planning Policy 2.4 Basic Raw Materials (BRM). The Perth Peel Region was subject to extensive interagency strategic BRM planning, including public consultation in 2015 and 2016.

This dataset comprises mapping associated with the State Planning Policy 2.4 Basic Raw Materials (BRM). Significant Geological Supplies (SGS) are those BRM areas identified by the DMIRS as having State significance due to the size of the resource, relative scarcity, demand and/or location near growth areas and transport routes. Most SGS areas are derived from, and therefore are a subset of, DMIRS published Regionally Significant Basic Raw Material mapping. Where this is not the case, they are derived using the same rule set as for the Regionally Significant Basic Raw Material mapping. Within the Perth and Peel Region, the SGS areas were further refined by an extensive interagency BRM planning process, which included public consultation in 2015. In the Perth and Peel Region, the SGS areas took into account environmental values, current and future land uses, including sequential land use opportunities, current and future infrastructure and BRM supply and demand considerations. BRM types shown are the dominant surface materials, but the application of the policy is not restricted to those materials. For example, a SGS area designated as ‘Sand’ may include limestone and gravel and the policy applies to all BRM derived from within those areas. The designation of an SGS area does not obligate a private landowner or State agency to extract these resources, nor does it presume that extraction would be environmentally acceptable or that subsequent approvals for extraction or environmental approvals are guaranteed. Planning policy associated with this mapping is documented in the State Planning Policy 2.4.
