Over 50 years ago, the Portland Development Commission (“PDC”) took the bold step of redeveloping a 55-block swath of the city as its first urban renewal project. And in what would become a tradition of making public space an intrinsic part of modern Portland’s urban fabric, the PDC set aside three full blocks and a series of adjoining streets for parks and garden-lined pedestrian walks. And to design the ensemble, the PDC hired one of the most visionary landscape architecture firms of the 20th century: Lawrence Halprin and Associates.

The Source Fountain, Lovejoy Fountain, Pettygrove Park, Forecourt Fountain (later named Ira Keller Fountain), and the adjacent pedestrian malls—collectively dubbed by Halprin as the Portland Open Space Sequence (the “Sequence”)—changed the history of American urban space, pioneering a path from passive parks and squares to more dynamic, participatory merging of parks and art.

Formed in 2001, the Halprin Landscape Conservancy (“the Conservancy”) is a non-profit organization under Sections 501 (c)(3) of the Internal Revenue Code. The Conservancy's mission is to honor and preserve the Sequence by increasing awareness of the Sequence as an important city and national cultural resource; improving the Sequence according to the original vision of Lawrence Halprin; and assuring the Sequence's upkeep at the level of a residential garden. Since its formation, the Conservancy has worked with the City, surrounding stakeholders, and donors to carry out several aspects of that mission.  

The Conservancy submitted a nomination to the National Parks Service, and the Sequence was designated as a National Historic Registry District on the National Register of Historic Places in March 2013.  The Conservancy is pursuing a National Historic Landmark designation at the National Park Service for the Sequence which will recognize the international significance of the Sequence and its architects.

The City's Parks, Maintenance, Transportation, and Water Bureaus all have had responsibility for the operation and maintenance of various elements of the Sequence through a 1979 Ordinance No 147584, titled: An Ordinance accepting the transfer of certain parcels of land for use as pedestrian malls located in the South Auditorium Urban Renewal Project to the City in accordance with Urban Renewal Plan from the Portland Development Commission, and declaring an emergency.

Over time, simple aging, along with deferred maintenance due to City budgeting challenges, have left the plazas and fountains in dire need of care and restoration.  The City recognized the international significance of the Sequence and wanted to seek additional support through charitable contributions and participation by the community. The City recognized the contributions of the Conservancy in support of these goals and the Council adopted Ordinance No. 184646 on June 8, 2011 authorizing an agreement with Halprin Landscape Conservancy to fundraise and undertake repair and maintenance of the fountains and surrounding park areas in the Portland Open Space Sequence.
