Methodology: Continuous exponential decay (base = 0.225 × e−0.467d), log-linear least-squares fit to Hite et al. (2001) quarry-only anchors (14%@1 mi, 9%@2 mi, 5.5%@3 mi) at the Aboite Township median home ($288k, ACS 2023). Industry factor 1.22× applied on top for quarry + asphalt + concrete + rail loading (informed by Simons 2006). LOS +10% for unscreened view (Boyle & Kiel 2001). Estimates carry a ±20% uncertainty band.

For awareness purposes only. This estimate is derived from published hedonic pricing research and is not a certified appraisal. Actual impact will vary based on site-specific conditions, market trends, and regulatory outcomes. Consult a licensed appraiser or environmental economist for legal or financial decisions.

Environmental Exposure at 1.8 Miles

  • Elevated particulate matter (PM2.5/PM10) — documented at distances up to 1.5 miles from active quarries under typical wind conditions
  • Heavy truck traffic on shared neighborhood roads — diesel exhaust, road wear, and safety concerns
  • Noise from rail spur — loading and switching operations for the proposed rail line
  • Light pollution from 24-hour industrial facility lighting

These impacts would persist for the 80–100 year operational life of the quarry. See the full research.

Note: County assessed values are typically below market value. Your actual loss may be higher. Decline estimates are synthesized from peer-reviewed hedonic pricing studies. No local appraisal specific to this site has been conducted. See methodology.
