10th@ Hoyt is the interior courtyard of an apartment complex in Portland, Oregon’s Pearl District. The design, by Koch Landscape Architecture is inspired by forms, textures, and colors of Persian gardens, presents an inward-oriented private oasis focused on a playful-yet-elegant illustration of stormwater collection, storage, and reuse. Stormwater from the roof travels down into the courtyard via copper downspouts in three locations; in each spot the water then travels via eye-catching chutes, runnels, and level spreaders of concrete, copper, and Cor-ten steel, eventually disappearing into raised basins filled with river stones. The water is then stored for up to 30 hours in a 4000 gallon cistern below grade. During the storage interval, the water is recirculated into elegant Cor-ten fountains in the courtyard. Detained runoff is then slowly released to the city stormwater system. Benjamin Rodes from Department of Landscape Architecture at University of Idaho has provided a Case Study of 10th@Hoyt.
