The Zidell block represents one ofPortland's largest brownfield restoration and secondary development sites. Thisproject is the first complete and complex integration of regional-scale greeninfrastructure in Portland. The project's focus demonstrates the great potentialof designers in pioneering design and planning to lead the city'sneighborhoods, from scales to stormwater systems to interchange hubs. Aftercareful deconstruction of various systems and strategies, it demonstrates ahighly productive design approach that covers the thinking of eco-blocks andlays the foundation for a broader range of projects. The project has no limitsand solves various problems, such as the flooding of rainstorms and thepotential development of the economy, showing the vision of landscapearchitects for a better city, incorporating imagination, design and solutions.

Designers are focusing on the comparison ofthe radio network and the focus network of green infrastructure solutions. Thiscomparison lays the groundwork for three scenario scenarios that are ultimatelyintegrated into a range of solutions needed for future green infrastructuredevelopment in brownfields. The diffuse + embedded scheme collects,communicates, and processes stormwater rain near the Zidell Yards area. As anevenly distributed network, the site's green infrastructure uses an integratedtechnology network to maximize stormwater filtration, incorporating eco-roofs,permeable paving and small green planting facilities. Aggregation +highlighting schemes integrate centralized and distributed systems through themanagement of storm submerged areas or settlements. This management technologyis specifically tailored to the building community, creating a distinctivemanagement area and settlement. In the center + focused program, storm water flowsthrough the open ditches network to large, centralized facilities in the area.Rainstorms in buildings and pavement areas are collected in sub-separated waterareas before being processed and filtered into large integrated facilities.

The design principles of greeninfrastructure are not limited to the environment of brownfield sites, but canbe transformed into new development and secondary development and fillingscenarios. Each scenario provides a viable green infrastructure solution, includingpublic spaces and private territories, where each element can be mashed intothe entire site while adapting to new development projects.
