Infrastructure Liability
Every mile of pipe laid and road paved is a legally binding contract to replace it in 30 to 50 years.
The Illusion of Free Infrastructure
Developers often build roads and sewers for new subdivisions and "donate" them to the city. Politicians celebrate this as free growth. In reality, the city has just accepted a multi-million dollar deferred liability.
If the tax yield of that low-density subdivision cannot cover the eventual replacement cost of that infrastructure, the city is mathematically doomed to default or drastically raise taxes.
Calculate Breakeven DensityThe Asset/Liability Mismatch
- Roads: 25-30 year lifespan. Cost: ~$1-2M per mile to reconstruct.
- Water/Sewer: 50-75 year lifespan. Cost: Massively variable based on density.
- The Tax Base: Low-density housing yields roughly $10,000/acre annually, nowhere near enough to cover the lifecycle cost of its requisite infrastructure footprint.
