GreenWorks provided planting and irrigation design services for the Jughandle Project. Specifically, GreenWorks worked closely with the City of Oregon City and OBEC Consulting Engineers in developing planting designs for the following:
• A distinctive new landscape gateway feature complementing a rehabilitated Oregon City sign at Prairie Schooner Way, featuring a striking planting palette of native and low-water, adaptive plants
• Pedestrian-friendly streetscapes and green street stormwater facilities along Washington Street, including a roundabout intersection at Clackamas River Drive
• Private property frontage improvements with strategic vegetative screening at key locations
In addition, GreenWorks worked with the City in developing a long-term planting approach for the 6-acre floodplain mitigation site, including almost 4,300 native deciduous and coniferous trees and 2,400 native shrubs.
• One significant aspect is the sheer scale of Jughandle Project. In addition to the large number of trees and shrubs being planted at the floodplain mitigation site, the City will be planting 82 new street trees, over 500 landscape trees, and over 25,000 shrubs and groundcover plants. This will have a substantial positive visual impact on this gateway into Oregon City.
To irrigate all of these plants, the City will be installing six separate irrigation systems, each of which are specifically designed with an efficient water delivery system. To minimize energy needs, the City will be installing solar-powered irrigation controllers for each of the six systems during the planting establishment period, after which they can be uninstalled and re-used on future Oregon City planting and irrigation projects.
