Phase 1: Water, power and buffers come before plot sales.
Raw water source and substation capacity are hardest to change once plots are sold. Baselines recorded now, including in the planned green belt, become the yardstick for the estate's environmental impact assessment (AMDAL) and PROPER for years.
What needs to be ready
1.1 Spatial approval and land status
Confirm the spatial-use approval (KKPR), ownership, occupants and any forest-estate boundary before the master plan is locked.
According to Government Regulation 28/2025
1.2 Raw water and power for the estate's lifetime
Model long-term tenant demand for water and electricity, then secure the bulk-water quota and substation capacity now.

- Energy+
1.3 Nature and buffer-village baseline
Record receiving-river quality, ambient air, flora and fauna in planned green space, and village livelihoods before heavy equipment arrives.
