When Impact Review and Soil Cleanup Are Triggered

  • Redevelopment on previously industrial or commercial parcels typically triggers a Phase I environmental site assessment requirement.
  • Discovery of contaminated soil during excavation may pause permitted work until a remediation plan is approved.
  • Public works or utility projects that expose suspect soils may require on-site containment and testing.
Site investigation often starts before major earthwork; contact planning early.
