From 2008 to 2018, NV5 assisted the project team, the City and the stakeholders with this park master plan and development covering nearly 25 acres of the former Killingsworth Fast Disposal Landfill. NV5 provided geotechnical and environmental support for the two final conceptual plans, including preliminary recommendations outlining the key geotechnical constraints for development, which involved landfill settlement and slope stability.
Environmental services included recommendations for maintaining the integrity of the landfill liner, modifications to the landfill gas extraction system and modifications to the leachate collection system to accommodate features of each conceptual plan.
NV5 also provided planning-level cost estimates and helped to facilitate construction and implementation the master plan elements. NV5 prepared the comprehensive Engineering Design Report, which included a site-specific Health and Safety Plan and a Soil/Solid Waste Management Plan. Additionally, NV5 provided engineering technical support and construction observation, working closely with the Oregon Department of Environmental Quality’s Brownfield and Solid Waste project managers.
Cully Park opened to the public in Summer 2018. This project received the Oregon Brownfields Redevelopment Award in 2018, the People’s Pick Poster Award at the 2019 National Brownfields Conference and the Daily Journal of Commerce Oregon Top Projects 2019 Award (Infrastructure – 3rd Place). Phase II of the park development is underway.
