Powell Butte Reservoir & Nature Park


Portland Water Bureau


Winterbrook managed the land use and environmental compliance process for the Powell Butte Reservoir #2 project, which included an update to the master plan for Powell Butte Nature Park.  Winterbrook staff participated in a series of Project Advisory Committee meetings, public workshops and open houses over the course of the two-year project.

In Phase 1 of the project, Winterbrook conducted environmental assessments, prepared mitigation plans and obtained land use permits for site preparation and excavation.

In Phase 2, Winterbrook guided the work of engineers, architects, and landscape architects in development of a reservoir and park plan that met local, state and federal regulations while building a broad base of public support.  Final land use and environmental permits were obtained in 2011 and the project is currently under construction.
