The new Duvall Library responds to the natural topography of the site by nestling a two-story structure into the steep hillside. Nakano Associates designed a landscape for the library that features distinctive stone paving, and a signature tree at the main entrance, in addition to verdant plantings and vines on trellises on all sides of the building. A green roof planted with sedums reduces the impact of stormwater runoff and replaces permeable area lost by the building footprint. Thanks to the steep grade of the site, the green roof also enlivens the territorial view available from the sidewalk at the upper edge of the site.
