• Plan wastewater and stormwater infrastructure based on land use planning principles described.
• Model hydrological impacts of land use change on groundwater and surface water resources.
• Identify areas vulnerable to water quality degradation from climate change and development pressures.
• Support cultural heritage preservation by mapping water resources with environmental and social values.

Strengths

• Policy became operational on a specific date: 18 December 2025.
• Replaces nine previous state planning policies, consolidating regulations.
• Available in multiple geospatial formats including GEOPACKAGE, SHP, and GEOJSON.

Limitations
