Infrastructure, people and geography continuously affect one another. Use overlays to understand pressure before it becomes failure.
Households move based on affordability, access, services and opportunity. Density changes demand patterns rather than simply adding capacity.
Industries consume inputs, create jobs and generate freight. Shortages propagate through local supply chains.
Generation, storage and transmission respond to peaks, weather and maintenance. Redundancy matters.
Residents and goods select routes using cost, time and capacity across multiple transport modes.
Water, heat, terrain and pollution shape health, agriculture and long-term expansion.
Budgets, service quality and policies affect trust, migration and district-level stability.
A simple zoning decision can produce transit, utility, budget and social effects over time.
| Phase | Immediate effect | Secondary pressure |
|---|---|---|
| 1 · Rezone | Housing capacity rises | Land value and construction demand increase |
| 2 · Move-in | Population grows | Power, water and services face higher peaks |
| 3 · Employment | More workers enter the network | Commute demand and freight conflicts increase |
| 4 · Response | Player expands transit and utilities | Maintenance costs rise |
| 5 · Adaptation | New capacity unlocks more growth | City form changes long-term demand |
