For the Portland Water Bureau, Winterbrook led the land use and environmental compliance tasks for a new below-ground reservoir and the historic redevelopment of open water features in the Washington Park Reservoirs Historic District.  The plan calls for replacement of aging reservoirs with new reflecting pools and the historic restoration of Romanesque Dams and Gatehouses.  A new, below-ground reservoir will maintain the historic drinking water function provided by the original reservoirs – but will be engineered to withstand ongoing landslide encroachment and potentially catastrophic effects of a major earthquake.

For the first time since the 1970s, John Charles Olmsted’s vision of publicly-accessible, open water features as a contemplative and relaxing counterpoint to the bustle of urban life will again become a reality.

The consolidated conditional use and historic review application was favorably reviewed by the Portland Landmarks Commission, the Portland Hearings Officer and the Portland City Council and the project is now under construction.
