After hearing concerns from residents and Vancouver city officials, Clark County commissioners on Tuesday decided against opening up 270 acres northeast of the Clark County Fairgrounds for development. Commissioners voted against a proposal that commissioners themselves had asked staff members to research and present.The land east of Interstate 5, identified in the county’s comprehensive plan as East Fairgrounds, will remain in “urban holding,” a designation given to land within the Urban Growth Area to prevent urban development until urban services are available. The East Fairgrounds area sits within Vancouver’s Urban Growth Area and the Discovery Corridor, which local politicians have been touting for the past decade as key to the region’s economic development. The proposal, which had been green-lighted by county staff members who said a traffic study confirmed the area could be developed, had been to open up 240 acres that would be zoned business park and 30 acres that would be zoned light industrial.Reasons for opposing the proposal varied. Residents said they did not want the land to be taken out of urban holding unless it was going to be zoned residential or mixed-use; city officials worried that the land in the Discovery Corridor, which is supposed to attract businesses that offer family-wage jobs, might be wasted if released too early.
