OMA提出了一项计划，意在全面遏制洪水和暴风雨对泽西城的影响。遵循国际惯例，由不同的团队为受桑迪飓风影响的区域提供设计计划，主题为“重新设计”。整体思路是在复杂的背景下，保护整个地区，并进行不同的独立设计。城市的供水策略是建立在详尽的研究上，并深入了解洪水的风险，确保大的项目相对集中并且高效。以期为类似项目提供参考经验，避免其他区域遭受同样的问题。

总体规划包括四个关键要素：抵抗——加强基础设施建设并建立景观化的海防；延迟——从政策、方针、基础设施等多方面来缓解雨水径流；存储——利用绿色基础设施收集过剩的雨水；释放——建立备用的排水渠道。作为防御暴风雨的根本，最重要的就是考虑到水位的问题，设计的防御措施的高度必须基于最极端的水位分析。为了应对洪水，“延迟”这一策略其实就是一块海绵，吸收处理大量的地面雨水。

威霍肯湾，一个公园景观作为防御屏障，保护该地区不受暴风雨和洪水侵害，这些湿地提供了天然的过滤器，同时加强社区休闲设施建设，并促进城市未来的发展。透水路面、雨水花园和生态调节沟都帮助城市管理地面水，进一步降低了洪水的风险，同时提高了城市的景观品质。

OMA has presented a comprehensive plan to curb the effects of flash flooding and storm surges across jersey city, hoboken and weehawken. the international practice are one of ten teams offering proposals for different sandy-affected regions, part of an ongoing initiative entitled ‘rebuild by design‘. identifying that individual and unconnected solutions do not work, the holistic approach acknowledges the density and complexity of the context, galvanizing and protecting the entire region.

the urban water strategy is based in the practice’s exhaustive research and understanding of flood risk, ensuring that the large-scale project is both focused and efficient. the innovations are imagined as replicable features that can be used in other areas suffering from similar problems.

the masterplan comprises four key elements: resist – programmed hard infrastructure and soft landscape for coastal defense; delay – policy recommendations, guidelines, and urban infrastructure to slow rainwater runoff; store – a circuit of interconnected green infrastructure to store and direct excess rainwater; discharge – pumps & alternative routes to support drainage.

as defense against storm surges is fundamentally a question of elevation, the height of the design’s defense measures is determined by an extreme water level analysis. in order to combat flash-flooding from rainfall, delay strategies act like a sponge. storage solutions temporarily take excess water out of the drainage system, which can be returned once capacity has been recovered. discharge plans comprising additional pumps and alternative drainage routes can increase the removal of liquid from the system, providing a robust, complete and cost effective defense.

at weehawken cove, a park landscape serves as a defensive barrier, protecting the region and its utilities from storm surges and flooding. these wetlands provide a natural filter, while simultaneously enhancing recreational amenities for the community and facilitating future development. permeable paving, rain gardens and bioswales help manage the city’s surface water – further reducing the risk of flash flooding while enhancing the cityscape.
