Location: Jameson Square, Portland OR.  This boardwalk was build as a tie to the other three parks in a series.  The boardwalk is not only a reference to proximity to water but also serves as a raised sidewalk to allow healthier growth of the trees by limiting compaction due to construction and allowing water to percolate through the spaces between the wood.  Materials: wood, metal.  Dimensions: ~16'-18'width.  Will need to be replaced eventually.
