Analysis

Cal Poly San Luis Obispo's environmental engineering graduates earn $82,197 in their first year—nearly $23,000 more than the California median and $16,000 above San Diego State, the next-best program in the state. This places the program in the 95th percentile nationally and 80th percentile statewide, delivering outcomes that rival far more selective universities. With debt of just $20,500 (matching the state median), graduates face a debt-to-earnings ratio of 0.25, meaning they could theoretically pay off their loans in three months of gross income.

The modest 3% earnings growth over four years might seem underwhelming, but it reflects strong starting salaries rather than weakness—when you begin at $82,000, rapid percentage gains become mathematically harder. The program's moderate sample size suggests steady enrollment, and Cal Poly's 30% admission rate makes this outcome accessible to good students who might not gain entry to Berkeley or Stanford.

For families seeking engineering value in California, this program delivers top-tier results at a public school price point. The combination of low debt and exceptional starting earnings creates immediate financial security, making this one of the strongest environmental engineering options on the West Coast.
