This guide explains the municipal and federal interaction, typical testing and remediation steps, how enforcement works, and practical actions developers should take before closing or beginning construction. It summarizes where to find official guidance and which offices to contact for inspections, permits, and complaints.

Overview

Brownfield assessment and cleanup involves site characterization (Phase I/II), a remediation plan when contamination is confirmed, and regulatory oversight. In Fort Collins, municipal permitting, land-use review and environmental health rules intersect with state and federal cleanup programs; developers often coordinate with the City, the Colorado Department of Public Health and Environment, and the U.S. EPA.

Applications & Forms

Required forms vary by agency.

For state and federal grant or cleanup applications, use the Colorado Department of Public Health and Environment and EPA Brownfields resources. [2]

Practical Steps for Developers

  • Phase I environmental site assessment to identify recognized environmental conditions.
  • If indicated, Phase II sampling and analysis by licensed environmental consultants.
  • Prepare remediation plan and permits; coordinate with City Planning/Building and state agencies where necessary.
  • Budget for remediation costs, monitoring, and potential escrow or financial assurance requirements.
