Infrastructure Cost Breakdown
Infrastructure is typically the single largest cost component in land development after the land itself. Accurate estimation is essential for project feasibility.

Lösungsbeispiel
30-lot subdivision with $420,000 roads, $180,000 water, $210,000 sewer, $120,000 electric/gas, $95,000 stormwater, $60,000 landscaping.
- 01Total infrastructure: $420,000 + $180,000 + $210,000 + $120,000 + $95,000 + $60,000 = $1,085,000
- 02Cost per lot: $1,085,000 / 30 = $36,167
- 03Roads per lot: $420,000 / 30 = $14,000
- 04Water per lot: $180,000 / 30 = $6,000
- 05Sewer per lot: $210,000 / 30 = $7,000
Häufig Gestellte Fragen
What is the biggest infrastructure cost driver?
Roads are typically the largest single infrastructure expense, accounting for 35-40% of total infrastructure cost. This includes the roadbed, paving, curbs, gutters, and sidewalks. The cost increases significantly with wider roads, heavier traffic specifications, or challenging terrain.
How do economies of scale affect per-lot costs?
Larger subdivisions generally have lower per-lot infrastructure costs because fixed costs (engineering, mobilization, main trunk lines) are spread over more lots. A 50-lot development may have 15-25% lower per-lot costs than a 15-lot development in the same area.
Can the municipality require me to oversize infrastructure?
Yes. Municipalities sometimes require developers to install oversized water mains, sewer lines, or roads to serve future development beyond the current project. In these cases, the developer may negotiate a reimbursement agreement for the oversizing cost from future developers who benefit from the capacity.
