A Zoning Map Amendment is being proposed for Block U, the proposed site for the new Multnomah County Health Department Headquarters. The change would enable the County to construction a building with a height of up to 150′. The site is currently zoned for 75′ maximum height, which the County believes in inadequate to support the 150,000 sq ft building they are proposing.
Current policy is to protect views of the Union Station clock tower from four locations: along NW 6th Ave; from the east bank of the Willamette at N Thunderbird Way; from the Steel Bridge; and from the Broadway Bridge. ZGF Architects have produced a number of images to illustrate the potential impact of a 150′ tall building from any of these designated points.
