300 miles of creeks lie beneath streets and buildings of Portland. In this segment of Locus Focus we explore a creek that flows under the streets of SE Portland and what the city is doing to recognize and replicate the important functions that creek once performed. Brooklyn Creek's headwaters are on the west slope of Mt. Tabor (a dormant volcano that hovers on the near horizon of SE Portland). Until it was culverted many years ago, the creek flowed through what are now the Sunnyside, Richmond, Hosford, Abernathy and Brooklyn neighborhoods, on its way to the Willamette River.
