Tanner Creek
Tanner Creek is a small tributary of the Willamette River in Portland in the U.S. state of Oregon. Named after a tannery owned by one of the city's founders, it begins in what is now the Sylvan–Highlands neighborhood in the Tualatin Mountains (West Hills) west of downtown. In the 19th century the creek flowed on the surface, running northeast across the city, past what later became Providence Park and into a shallow lake (Couch Lake) and wetlands in what became the Pearl District, bordering the river. Late in the century, the city began re-routing Tanner Creek and other West Hills streams into combined sewers and filling their former channels and basins to make flat land for homes and businesses. In the 21st century, Tanner Creek is nearly invisible, flowing through a conduit (but not a combined sewer) that empties into the Willamette at Outfall 11, near the Broadway Bridge. Structures along the former course of the creek include Vista Bridge and Tanner Springs Park as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tualatin Valley
The Tualatin Valley is a farming and suburban region southwest of Portland, Oregon in the United States. The valley is formed by the meandering Tualatin River, a tributary of the Willamette River at the northwest corner of the Willamette Valley, east of the Northern Oregon Coast Range. Most of the valley is located within Washington County, separated from Portland by the Tualatin Mountains. Communities in the Tualatin Valley include Banks, Forest Grove, Cornelius, Hillsboro, Aloha, Beaverton, Sherwood, Tigard, and Tualatin. History In the early 19th century, the valley was inhabited by the Atfalati, a hunter-gatherer Kalapuyan band that spoke a dialect of Northern Kalapuyan. In the middle 19th century, the Atfalati lived in several villages in the valley, including Chakeipi ("Place of the Beaver", translated by early white settlers as "Beaver Dam"). Early Euro-American settlers called the valley the "Twality Plains", a corruption of the name of the Atfalati tribe. Ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

West Side CSO Tunnel
Eastside Big Pipe under construction The West Side Combined Sewer Overflow Tunnel (also West Side Big Pipe) is a tunnel in Portland, Oregon, United States. It receives and stores overflow from the combined sewer system before it can reach the Willamette River. The main tunnel is in diameter and long for a capacity of and connects to dozens of smaller sewer overflow interceptors along the west side of the Willamette River. The tunnel receives flows that might otherwise reach the river. Instead, the CSO tunnel transports them to the Swan Island Pump Station. Portland's 1930s sewer design combined street and surface runoff with sewage in a common system that was overwhelmed during heavy precipitation. The original system handled overflows by sending excess flow into the river. The tunnel is below ground level. It passes under the Willamette River between the NW Nicolai Street shaft () to the confluent vertical shaft on Swan Island (), which also receives the East Side Bi ...
