Neighborhoods and towns covered around Portland

Each area page keeps to what is true of that place: when its houses were built, what they sit on, which creeks and roads run through it and the water problems that come up there. Portland has its combined sewers and West Hills, Milwaukie and Gresham share Johnson Creek, and Fairview and Troutdale sit inside the Columbia levee system.

Two of the towns are in Washington. Vancouver and Camas are in Clark County, where contractors register with the state Department of Labor & Industries rather than Oregon's CCB. The western towns, such as Beaverton, Tigard, Tualatin and Hillsboro, face Fanno Creek, Beaverton Creek and the Tualatin River instead.
