Centennial Mills Project
PDC acquired Centennial Mills from ADM Milling Company in 2000 using urban renewal and City of Portland Bureau of Environmental Services (BES) funds. The property was acquired to fulfill the River District Urban Renewal Plan's stated objective of enhancing the waterfront with public open spaces and to facilitate connectivity between the River District, the Willamette River and the Willamette River Greenway.
In 2006, PDC together with the Bureau of Planning completed the Centennial Mills Framework Plan which outlines Portland's interest and aspirations for redevelopment of the site. The framework plan is the result of a six month public process and was approved by the Portland City Council in December 2006. The plan does not posit particular redevelopment schemes for the property. Rather, it outlines various development opportunities and lays out five key principles to guide redevelopment: Provide Open Space, Capture History, Define a Community Focal Point, Strengthen Connections, and Embrace Sustainability. Redevelopment of the site is also anticipated to further the goals of the city's Economic Development Strategy.
In March 2013, PDC and Harsch Investment Properties signed a non-binding Memorandum of Understanding, summarizing the intent of both parties to work toward a successful negotiation of a binding disposition and development agreement for redevelopment of the Centennial Mills site.
In December 2014, the PDC Board adopted Resolution 7089, making an emergency declaration relating to the current condition of Centennial Mills, and instructed staff to seek a contractor for the selective demolition and salvage of the property. PDC announced in March 2015 the selection of Tigard, OR-based Northwest Demolition & Dismantling as the Construction Manager/General Contractor (CMGC) for that work.
From April to June 2015, PDC staff, with assistance from KLK Consulting and Northwest Demolition and Dismantling, performed a series of pre-demolition investigations to determine the scope, schedule, and safety measures necessary for accomplishing the selective demolition of the site.
The Mounted Patrol Unit vacated the site on May 31, 2015, relocating its daily operational offices to the east end of the Hawthorne Bridge. The horse stables have been relocated to the Lake Oswego Hunt Club
On July 16, the PDC Board of Commissioners approved Resolution 7137
, beginning the first phase of the selective demolition of Centennial Mills. While the resolution excluded demolition of the Feed and Flour Mill buildings, the Mayor’s office has requested additional investigation into the costs and feasibility of preserving these structures.
Early preparatory work began on site in August and September 2015. Work included installation of temporary roadways for heavy equipment, utilities termination and rerouting, artifact salvage, and temporary structural shoring. During this period, demolition crews witnessed several instances of structural collapse and accelerating deterioration. Due to the heightened danger, non-demolition personnel are no longer permitted on the Property.
Phase One demolition of Warehouses A, B, C, D, and F as well as Elevators A, B, and C began the first week of October 2015 and will conclude in June 2016. Phase Two of the demolition is scheduled to begin in July 2016.
