2008年北卡罗莱纳州达勒姆遭遇创纪录的干旱,导致全市范围内要求减少饮用水消耗。认识到城市的挑战,杜克大学试图减少他们的冷冻机系统的摄入量,在这一点上每年大约用1亿4000万加仑为校园内的建筑提供空调。一个工程团队提出了一个拦蓄池来收集来自校园的径流,NBW也加入了这个项目,使其超越了严格的基础设施,以体现该场地的生态、教育和娱乐潜力。

这是一个如何将基础设施转化为场所建设的问题。然后是关于智能工程和智能设计——以及它们如何协同工作的问题。“杜克大学的常驻景观设计师马克·霍夫”,

该项目占地12英亩,其中约一半被蓄水池占据,根据降雨量,蓄水池的水位在8至12英尺之间。20世纪20年代,当奥尔姆斯特德兄弟设计了校园总体规划时,他们打算在这个遗址附近安装一个湖,但当时由于财政拮据而被排除在外。这个项目完成了他们近一个世纪的愿景。

“水塘沿沙溪路线布置,可根据需要通过进出口调节水位,使水塘在通过时有独特的机会改善雨水水质。前池允许沉积物沉淀,而大量湿地植物在水流向下游受威胁的河流系统之前过滤掉磷。

在池塘开发之前,倾斜的河岸上长满了入侵物,侵蚀使沉积物流入河流。新的池塘利用由秃塞浦路斯二级杉构成的湿地架子,提供不同层次的生长,提供视觉趣味,同时有助于小湖泊的生态性能。

池塘也可作为沉浸式教育资源,如NBW的埃文格林所解释;“我们与尼科尔森环境学院的教授合作,开发完全是本地物种的植物,因此它可以用作室外教室。”

建设始于2013年4月,历时两年才完全完成。在整个设计和实施过程中,特别注意确保对该地区的破坏最小,并以反映项目精神的方式使用材料。树木是通过对场地进行仔细的分级而保存下来的,或在建筑中用作木材;石头来自大学自己的采石场。

“一系列的路径为大学和大达勒姆社区提供了便捷的通道,同时设计提供了一系列主动和被动的参与机会,从圆形剧场的小型集会到安静的学习区域。修复后的栖息地还允许学生和教员监控功能并进行现场研究项目。

In 2008 Durham North Carolina experienced record drought, resulting in a city-wide mandate to reduce potable water consumption. Recognizing the city’s challenge, Duke University sought to reduce the intake of their chiller system, which at that point was using approximately 140 million gallons each year for providing air conditioning for buildings on campus. An engineering team proposed a retaining pond to collect runoff from the campus and NBW was brought on board to evolve this project beyond strict infrastructure to manifest the ecological, educational, and recreational potential of the site.

“It was a question of how to turn infrastructure into place-making. Then it was about smart engineering and smart design – and how they can work together.” Mark Hough, Duke University’s resident landscape architect.

The project area spans twelve acres, about half of which are occupied by the retention pond with between eight and twelve feet of water depending on rainfall. When the Olmsted brothers designed the campus master plan in the 1920s, they intended to install a lake within proximity of this site, but at the time it was ruled out due to financial constraints. This project brings to completion their vision nearly a century in the making.

The pond is placed along the route of Sandy Creek, allowing it to regulate water levels as needed through inflow and outflow and giving the pond the unique opportunity to improve stormwater quality as it passes through. A forebay allows sediment to settle while a multitude of wetland plants filter out phosphorus before the water travels to the threatened river system downstream.

Prior to the pond development, the sloped stream banks were overgrown with invasives and erosion allowed sediment to run off into the stream. The new pond utilizes wetland shelves, structured by Bald Cyprus Taxodium distichum, to provide distinct tiers of growth that provide visual interest while contributing to the ecological performance of the small lake.

Altogether around95,000 wetland plants and 2,500 trees were installed across the site, creating a thriving and diverse habitat for wildlife and pollinators. The plants span emergent, wetland, and upland growing conditions, and are tolerant to seasonal fluctuations in water level.

The pond also serves as an immersive educational resource, as explained by NBW’s Evan Grimm; “We worked with the Nicholson School of Environment professors to develop plantings that are entirely native species, so it can be used as an outdoor classroom.”

Construction began in April 2013 and took two years to fully complete. Throughout the design and implementation process, special care was taken to ensure minimal disruption to the area and to use materials in ways that reflected the ethos of the project. Trees were preserved through careful grading of the site or utilized as lumber in the construction; the stone was sourced from the University’s own quarry.

A series of paths provide easy access for the University and the greater Durham community while the design provides an array of active and passive engagement opportunities from small gatherings in the amphitheater to quiet study areas. The restored habitat also allows students and faculty to monitor the functionality and conduct onsite research projects.

The resulting design balances natural and cultural elements while reducing the University’s annual use of potable city water by roughly 200 million gallons all while significantly enriching the campus with a beautiful and engaging civic space.
