Pettygrove is the second of four parks designed by Lawrence Halprin as part of the Portland Sequence. This park is often forgotten since it’s design was less revolutionary than either Forecourt Fountain or Lovejoy Fountain, two of the other parks in the sequence. However, this park has the most ties to the Northwest and the history of park design. Local basalt, deposited here during one of many lava flows that spanned the region thousands of years ago, is crafted into low stone walls which are modeled after those found along the historic Columbia River Gorge Highway. The park’s miniature pastoral design recalls the work of Frederick Law Olmsted, especially his design for Central Park. My favorite design feature stems from how the linear elements play off each other – the silver 60s era light standards against the warm brown bark of the shade trees.
