The coalition in charge of utilization of a $600,000 grant from the Environmental Protection Agency to spur economic development and revitalize underdeveloped parcels in and around The Dalles says it is working with several property owners on redevelopment planning and is seeking others, including those with parcels that could benefit from environmental site assessment.  Wasco County and the City and the Port of The Dalles make up the Brownfields Revitalization Committee.  In a statement released Wednesday, the governmental agencies say they are working with property owners on diverse projects including preparation to develop workforce housing in a mixed-use development in The Dalles, removing an old fuel tank from a downtown property, evaluating an old auto wrecking yard for potential redevelopment, and helping North Central Public Health District with an environmental assessment and hazardous materials survey on one of its properties.  The coalition says it is looking for more properties to help.   Contact the Brownfield Revitalization Coordinator, Jim Schwinof at 541-296-5481, ext 1131.
