ONTARIO A post on the City of Ontarioâs Facebook page on May 25 is asking the community about the existence of properties that may be considered âbrownfields.â The program being advertised is called the Ontario-Malheur Brownfield Revitalization. To find out more about this terminology and what kind of assistance is available, the newspaper reached out to Ontario Community Development Director Dan Cummings, who responded in an email on May 27. âBrownfields are properties that are not living up to their potential because of known or suspected environmental issues. Common examples are old, vacant dry cleaners, gas stations/auto repair sites, or industrial/manufacturing sites. But vacant or underused lots or vacant/partially vacant buildings can also be considered brownfields because unknowns about past use may be limiting redevelopment,â wrote Cummings.
