Methodology & Local Data Sources
How we estimate rain garden installation costs in Madison: Our local cost figure of $5,553 for Madison, WI is calculated by adjusting the national mid-range baseline of $5,000 using two location-specific factors:
- Labor adjustment, 55% of the project cost is treated as labor. That share is scaled by the ratio of the BLS OEWS May 2025 median hourly wage for Construction laborers in the Madison, WI metro ($27.40/hr) to the U.S. median for the same occupation ($22.66/hr), a factor of 1.21. BLS publishes employee wages, not contractor billing rates, so only the ratio is used; the wage itself is not a quote.
- Materials adjustment, 45% of cost is treated as materials, scaled by HammerIO's modeled material cost index for Madison of 99 (national baseline = 100). The BLS Producer Price Index tracks national construction-material price trends; it does not publish a city-level index, so this regional factor is an estimate.
- Permit fees are shown as a modeled allowance of $1,066 for Madison. Actual permit costs follow the local fee schedule and vary by project scope, valuation, and inspection requirements set by the local building department.
- Scope pricing for this project in Madison: quotes should be compared by equipment, design, access, permit, and finish assumptions rather than a square-foot shortcut.
