Hood River’s Urban Renewal Agency Board approved the Heights Streetscape preferred design and implementation plan.  The plan puts projects in three groups:  key circulation, small pedestrian and bicycle projects, and filling in blocks.  Key circulation is the major group, and includes a roundabout at 13th and May, Belmont Road intersections with 12th and 13th Streets, a 12th Street bike connection to Pacific Avenue, and improvements to May Street.  Nathan Polanski of consultant MIG said besides the obvious hurdle of funding, getting sign off from the Oregon Department of Transportation is among the bigger challenges for the project.  URA board chair Mark Zanmiller said the challenge before them is to get the foundational traffic flow done.
