洛杉矶河在上个世纪的一次转折后经历了戏剧化的转变。1938年一次毁灭性的洪水过后,工程兵团用混凝土重铸了她的河床和驳岸。此后,河流主要作为排放过载雨水的防洪渠道。于2008年1月份公布的“洛杉矶河总体规划”,要求将其51英里混凝土衬砌的水道恢复到自然状态。 2016年,有关于洛杉矶河的数据和相关信息对外公开,作为用于描述/分析/了解洛杉矶河的重要因素,并为河道振兴的规划带来的益处。重建洛杉矶河一直是加州洛杉矶市持续进行的项目。

The Los Angeles River has experienced dramatic changes since the turn of the last century. After the devastating flood of 1938, the army corps of engineers encased its riverbed and banks in concrete. Since then, the river has served primarily as a flood control channel fed by storm drains. The Los Angeles River Master Plan was unveiled in January of 2008 calling for the restoration of most of its 51-mile concrete-lined waterway to its natural state. In 2016, the LA River index was released online. The LA River Index shows data and relevant information to describe/analyze/understand important factors about the Los Angeles River, and it projects possible benefits generated by its revitalization. The rehabilitation of the Los Angeles River has been an on-going project in the city of Los Angeles, California.

MetropolitanmomentuM 事务所的设计师为洛杉矶河重新描绘了两段独特的景观构成。其中一个项目是洛杉矶河居住桥梁。它是围绕洛杉矶大桥第一街建成的新建筑。与现有的历史高架桥完全脱离。它被设计为通向城市,地方生态系统、艺术、文化及其他多样性空间的门户。桥梁两侧的多个垂直交通塔将游客和居民带入上层空间体验桥上多层次的滨河景观。住宅,办公和零售空间位于最高层。人行道,受保护的自行车道和汽车道位于第一街大桥的底层。桥梁连接洛杉矶河的两岸,它附带的公园在底层。洛杉矶河公园同时希望为居民提供各种活动,包括社区/教育花园,娱乐区,艺术和运动区。

MetropolitanmomentuM reimagines two segments of the Los Angeles River with two distinctly unique projects. One of these projects is the Los Angeles River Habitable Bridge. It is a new structure built around the 1stStreet Los Angeles Bridge. It is completely detached from the existing historical viaduct. It is designed as a gateway that welcomes people to the city, its local ecosystems, and its diverse art and culture. Multiple vertical circulation towers located at both sides of the bridge welcome visitors and residents to experience multiple levels above the river. Residential, office and retail spaces are located at the top levels. A sidewalk, protected bicycle lanes, light-rail, and automobile lanes are located at the 1st Street Bridge level. It connects to the Los Angeles River, and its proposed parks at the ground floor level. Los Angeles River parks are ambitioned to offer a variety of activities including community/educational gardens, recreational areas, art, and sports.

该项目靠近社区、公共艺术、公园和自然栖息地,处在一个对整个城市空间来说非常主要的位置。随着对洛杉矶市区私人汽车的减少以及城市密度增加的预测,公共交通运输,服务业将在近期重塑城市景观。因此,该项目建议为城市现有道路,停车场和基础设施配置新功能空间。

The project connects communities, public art, parks, and natural habitats together at one main location. It also anticipates the reduction of private motor vehicles in downtown Los Angeles and the increase of urban density. Public transportation, ridesharing, autonomous vehicles, and private mobility services are expected to reshape the urban landscape in the near future. Therefore, it proposes the allocation of new functions to the city’s existing roads, parking lots, and infrastructure.

该项目旨在建立沿主要道路运行的双向自行车道,并呼吁市民使用更多的公共交通工具。建议将未被充分利用的现有停车场重新设计为植被区/公园/花园。 主张去除不必要的人行道/硬质表面,包括沿洛杉矶河岸的一部分区域。洛杉矶河可居住桥梁被设计为一个通道以及目的地,以悬挂的水平大型结构连接当地社区、现有的基础设施、新的公园和自然生境。使得洛杉矶的大区内的功能被整合在一起。

The project calls for a two-way protected bicycle lane running along all of its main roads, and the use of more public transportation. It alsorecommends redesigning underutilized existing parking lots as vegetated areas/parks/gardens. It proposes the removal of unnecessary pavement/concrete surfaces including specific areas along the Los Angeles River banks. The Los Angeles River Habitable Bridge is designed as a gateway and a local destination in the form of a suspended horizontal megastructure that connects local communities, existing infrastructure, new parks, and natural habitats within the Los Angeles metropolitan area closer together.

第二个项目是河道旁的一处花园,为濒危植物物种的临时处理提供了动态监测和控制环境。花园在洛杉矶历史悠久的国家公园内展示了这些独特的植物。花园里展示的这些独特的植物,位于洛杉矶历史悠久的州立公园旁,毗邻洛杉矶河。它为当今森林和植物的困难生境,包括当地的生态系统,带去了一丝曙光。这个项目是为了让大自然激发内城市内的人对景观环境的渴求。因此,根据植物的需要,花园内的结构被建成透明的,半封闭的或完全开放的。它们将植升高,使其根部像叶片一样暴露在空气中。灌溉系统将冷凝后的水分和养分混合,植物将从冷凝塔中吸收这些营养。 雾培系统将水溶液直接喷洒到他们的根系来培育这些植物。

The second project is a garden by the river, and it is named the Floating Gardens*. The garden offers a dynamic monitored and controlled environment for the temporary treatment of endangered plants species. The garden showcases these unique plants within the Los Angeles Historic State Park located next to the Los Angeles River. It brings to light the difficult challenges forests and plants are facing today, and they include local ecosystems. The garden is also meant to let nature inspire people within an inner-city park. The structures are mediators between nature and man-made systems. Thus, the garden's structures are transparent, semi-enclosed, or completely open depending on the plants’ needs. They elevate plants, and they expose their roots the same way they expose their leaves.The irrigation system absorbs moisture from the environment using moisture collecting towers via condensation, and it mixes its water with nutrients. Aeroponic systems spray the water solution directly to their visible roots to feed them.

当人们从洛杉矶历史国家公园或洛杉矶河进入到漂浮花园时,他们会看到生长在空中的植物。随着植物逐渐更新,地面的设计会引导人们通过花园。它将他们带到透明结构之下,游人们可以看到清晰、俏皮、动态的植物生长过程。它是一个新的城市公园,将社区、自然、人造结构和环境聚集在一起。

As people approach the vertical garden from the Los Angeles Historic State Park or from the Los Angeles River, they see its vegetation elevated in the air. The plants gradually reveal more of themselves. The ground is designed to guide people through the garden. It takes them underneath the transparent structures. They are clear, playful, and dynamic. It is a new urban park where communities, nature, man-made structures, and environmental systems come together.

MetropolitanmomentuM 通过这两个截然不同的项目重新描绘了洛杉矶河的空间,但他们都对于该区域未来的重建以及与现有城市结构,当地社区与河流有形和无形的联系有着类似的指导思想。洛杉矶河居住桥梁和浮动花园两个项目的核心都是河流的恢复和发展。其中一个主要的原因是,公园和公共空间中可以举办一些在其他城市空间中不能进行的大量的活动。此外,位于大都市核心的公园,对提升市民生活质量至关重要。因此,这两个项目旨在直接连接到未来的自然植被和沿河开放的公共空间。他们协调并提出了该地区的重建工作,在现有的基础设施,自然,技术,艺术,多样性和洛杉矶市的城市增长的密度之间取得平衡。

MetropolitanmomentuM reimagines the Los Angeles River with these two distinctively different projects, but both of them embrace similar ideas regarding the future redevelopment of the region and its tangible and intangible connections to their existing urban fabric, local communities, and the river. The Los Angeles River Habitable Bridge and the Floating Gardens place the rehabilitation of the river and the development if its future parks at the heart of their general vision. One of the main reasons for this is the idea that parks and open public space allow for a multitude of activities in ways no other urban space can. Also, parks are at the heart of a well-balanced metropolis, and they can be essential to a good quality of life. Consequently, both of these projects aim to connect directly to future vegetated areas and open public spaces along the river. And, they anticipate and propose a coordinated redevelopment effort of this region embracing a balance between existing infrastructure, nature, new technologies, art, diversity, and the increase of urban density in the city of Los Angeles.
