The city will prepare an inventory of such properties, which may contain hazardous substances, pollutants, petroleum, or other contaminants that hinder their redevelopment. Typical sites include closed gas stations, former industrial sites, dry cleaners, and landfills.

The city will prepare an inventory of brownfields sites on O'ahu and conduct environmental studies on two to five of those sites that have the best potential for redevelopment. The Department of Community Services is managing the project in cooperation with the Department of Environmental Services and the project consultant, Environmental Resource Management.

The city is seeking input from the public to identify properties that may be candidates for a brownfields review.
