The $10,000 Phase I ESA Problem

Phase I ESAs are essential for CERCLA liability protection but expensive for screening 15 potential sites ($45K-$150K).

Pre-Screening: The Missing Step

Screen with publicly available data: FEMA flood zones, EPA brownfields, USFWS wetlands, USFS wildfire risk, EPA air quality.

The Workflow

Automated screening (seconds per parcel) → flag and rank → Phase I ESA only for parcels that pass screening. Cuts ESA spending by 60-80%.
