The City of Bend, Oregon, has gone a long way towards preserving natural vegetation along the shore of the Deschutes River, which flows through the city.
But heavy pedestrian use of the area, insufficient barriers, and grey infrastructure upstream fail to adequately protect water quality. Away from the stream bank, Bend has all the usual urban problems of polluted runoff.
Bend has excellent landscape design in waterfront parks, but in the rest of the city, it has all the usual urban problems with stormwater runoff.
