项目概述
蒙哥马利西南绿街是一项新兴的都市街道规划,使波兰在国内外的知名度不断上升。该规划覆盖多个街区,整合了这条市中心新兴街道的各种环保基础设施及可选交通策略。蒙哥马利西南绿街被认为是波兰迄今为止最大胆且最具创新性的市中心绿色街道项目。
 
项目描述
波兰发展委员会、波兰环境署、波兰州立大学及发展公司通力合作,力求制定一个覆盖五个街区的规划,整合从西南第十一大街经蒙哥马利西南街到东面的柏蒂格罗夫公园一带的各种可持续雨水管理策略。波兰市中心大学校区规划强调校园社区的发展,使之符合波兰市的发展目标,并使蒙哥马利西南街成为一个重要的东/西向人行廊道。蒙哥马利西南街沿路的多街区开发及再开发项目将以波兰市政府、波兰州立大学、私人开发商及各大企业在过去四十几年的长期努力为基础同时开展。这些元素的战略集合将成功激发社区活力,增强步行体验,促进可持续发展,并继续打造社区文化。蒙哥马利西南绿街规划表明,即使是在最城市化的的情况下,市中心街道也能通过规划和改造对雨水径流进行全面管理,打造、整合及保留活跃的步行空间。景观设计师根据要求发挥主要作用,以打造一个高度整合的城市步行街道景观愿景,从而使该廊道沿路的各种环保基础设施策略得以融为一体,包括雨水沼泽、花坛、绿植墙、绿色屋顶、巧妙的雨水引流及至关重要的无路缘街道设计。
项目总体目标
蒙哥马利西南绿街规划旨在实现为项目周围地区所制定的多个目标,其中有不少总体目标早在项目组开展规划工作时就已确定,包括:
· 提升波兰目前作为合作与创新型可持续设计和发展孵化基地的知名度;
· 将可持续雨水管理方法引入场地设计,并凸显都市活力环境的所有元素,从而形成一种可持续实践模式;
· 在大学、喷泉、公园、礼堂、博物馆、剧院及商场等便利设施之间建立主要通行途径,缩短市中心商务区的上下班路程,并通过有轨电车、轻轨电车及转运站的各条汽车路线连接大都市区域;
· 成功将城市中心广场扩展为活力四射的城市广场,并将其成果应用到整个项目廊道中;
· 结合设计愿景,使西山区与蒙哥马利西南街沿路的威拉米特河相连;
· 利用蒙哥马利西南绿街将整个地区与环保区联系起来。
绿街具体目标
除了以上所述总体目标外,景观设计师还需根据委托,为实现蒙哥马利西南项目廊道的具体绿街设计目标提供帮助,该目标包括:
· 建造宽阔的步道及无路缘街道,以方便底层零售区附近的各种景观设施建设。设有机动车道的街区应设有活跃的零售区,且应同时建有行车道及停车道,以便在举办特殊活动时,封闭道路,仅供行人通行;
· 引入能够形成视觉连贯性的景观元素,使之成为主要的雨水渠道或贯穿多个社区的共同主线,同时打造一条东西走向的环保通道,从而使市中心与波兰州立大学校区相连;
· 将拥有道路优先权的绿街设计与附近的开发项目结合,包括已规划的俄勒冈州可持续发展中心。发掘建造可同时吸纳街道及建筑屋顶径流的雨水共享花坛潜力;
· 改造项目廊道沿路的绿街元素,同时凸显南方公园社区、城市中心广场及柏蒂格罗夫公园的特色。
项目分析与实施
为全面实现蒙哥马利西南绿街规划,景观设计师需对该项目的场地特征进行研究,制定雨水管理总体目标,调查并针对该场地的限制因素采取应对措施,确定建设绿色街道的可行性,分析贯穿社区的各种交通模式。项目分析使180万加仑的雨水径流得以通过绿街的雨水主渠道进行管理,使该地区的重要交通模式得以从机动车基础设施向人行基础设施转变,同时使该街道的建设得以促进蒙哥马利西南绿街廊道一带的可持续私人再开发项目。这些分析最终促成了蒙哥马利西南绿街的规划,且经实践证明,该规划在短期及长期内均具有极高的可行性。蒙哥马利西南绿街规划正在进行多期项目的建设。景观设计团队已成功完成规划中的两个街区,即史密斯纪念馆学生会广场及城市中心广场改造项目。预计未来两年还将建造另外两个街区,包括拟定的俄勒冈州可持续发展中心——波兰最先进的绿色建筑,该建筑力求符合最严苛的“生态建筑挑战”标准。通过各方人士的战略合作及持续不断的规划与实施工作,蒙哥马利西南绿街走廊必将成功激发社区活力,在学术、住宅及商业社区之间形成可持续发展关系。该项目的实施将为街道规划树立新的理念,并为波兰及其他地区的市中心街道景观项目提供场地营造模式。

蒙哥马利西南绿街被认为是波兰最具创新性的绿色街道项目。该项目表明,即使是在最城市化的的情况下,市中心街道也能通过规划和改造对雨水径流进行综合管理,打造、整合及保留活跃的步行空间
The SW Montgomery Green Street is regarded as Portland's most innovative green street effort. The project demonstrates how, in even the most ultra-urban conditions, downtown streets can be planned and retrofitted not only to fully manage stormwater runoff but to also create, integrate, and preserve vibrant pedestrian spaces.

蒙哥马利西南绿街有五处核心区域会对用户模式产生影响:公园街区中心、城市入口、生活/学习中心、市中心以及南部滨水区。这些区域有望成为蒙哥马利西南绿街沿路率先实施的再开发项目
There are five focal points that will influence user patterns on the SW Montgomery Green Street: The Park Blocks Center, City Gateway, Living/Learning Center, Downtown Core, and the South Waterfront District. These areas should be expected to lead early redevelopment efforts along the SW Montgomery Green Street.

波兰1988年的中心城市规划将蒙哥马利西南街划定为重要的东西向人行廊道。在过去五年里,波兰市政府、波兰州立大学、私人开发商及各大企业集中发力,沿蒙哥马利西南街同时实施多街区开发及再开发项目。这些元素的战略集合将成功激发社区活力,增强步行体验,促进可持续发展,接续打造社区文化,同时着重以各组织机构在过去四十几年的长期努力为基础实施建设
Portland's 1988 Central City Plan designated SW Montgomery Street as a key east/west pedestrian corridor. In the last five years, there has been a concentrated effort by the City of Portland, Portland State University, private developers, and businesses to implement simultaneous multi-block development and redevelopment along SW Montgomery Street. The strategic convergence of these elements will successfully activate the neighborhood, enhance the pedestrian experience, foster sustainability, continue to build a community culture, and dramatically build upon the long-term efforts advanced over the past four decades.

蒙哥马利西南街具有兼收并蓄的特性。从郁郁葱葱且适合沉思冥想的柏蒂格罗夫公园到俄勒冈州可持续发展中心周围的可持续尖端设计,该廊道连接着诸多与众不同的空间。蒙哥马利西南绿街旨在保护和提升廊道沿途的各种独特空间,并加强与周围便利设施的联系。但是,和多数市中心雨水改造工作所面临的处境一样,设计团队也需要解决城市设计及雨水管理所面临的场地限制问题
The character of SW Montgomery Street is eclectic by nature. The corridor links a diverse collection of spaces from the verdant, contemplative Pettygrove Park to the cutting-edge sustainable design surrounding the Oregon Sustainability Center. The SW Montgomery Green Street seeks to preserve and enhance the unique spaces along the corridor and provide strong connections to surrounding amenities. However, like most downtown stormwater retrofit conditions, there are a variety of urban design and stormwater management site constraints that the design team needed to address.

这一最高水准的绿街项目不仅具有管理雨水径流的功能,还能促进交通模式的转变,使该街道从以机动车为主要交通工具转变为具有多种交通选择。蒙哥马利西南绿街通过权衡各种交通选择示范了完整的街道规划,同时着重强调增强步行及自行车基础设施的建设
The highest caliber green street looks beyond only managing stormwater runoff. It also promotes a transportation mode switch from primarily auto-centric design to a street that emphasizes alternative transportation. The SW Montgomery Green Street exemplifies complete street planning by providing a balanced set of transportation choices, but also provides a clear emphasis on enhanced pedestrian and bicycle infrastructure.

蒙哥马利西南绿街的雨水管理设施并非适用廊道内所有的街区。在许多情况下,由于地下设施或结构的存在,绿街的雨水渠道无法渗透雨水径流,因此可能需要使用溢流式雨水设施。当然,这并不排除对雨水管理景观系统的利用。恰恰相反,该设计建议着力实现城市雨水径流管理的非渗透性目标
Stormwater management along the SW Montgomery Green Street is not a one-size-fits-all condition for each block of the corridor. In many cases, the street's"stormwater spine"will not be able to infiltrate stormwater runoff due to underground utilities or structures and may force the use of flow-through stormwater facilities. This of course does not preclude using a landscaped-based system of stormwater management. Instead, it suggests focusing on non-infiltrative goals for managing urban stormwater runoff.

沿蒙哥马利西南绿街不断延伸的雨水渠道设计为一个极为实用的景观系统,用于收集和管理75 000多平方英尺(约0.7公顷)非渗透区的雨水径流。该渠道是该项目场地进行雨水管理的主力,穿行于廊道内的各个街区。不过,该景观系统的形态大小因地制宜,以适应各个街区的独特状况
The continuous stormwater spine along the SW Montgomery Green Street is planned as a highly functional landscape system used to capture and manage stormwater runoff from over 75,000 square feet of impervious area. The spine is the project site's"workhorse"for stormwater management. Each block along the corridor has the stormwater spine traversing through it, however, the form and size of the landscape system does vary in response to the unique conditions of each block.

蒙哥马利西南绿街全面建成后,每年可管理上千万加仑的雨水径流。但是,绿街建设并非千篇一律,该街道能达到何种绿色程度取决于多种因素。对于某些绿街而言,尤其是蒙哥马利西南绿街,每个单独的街区均可左右绿街的宏伟蓝图
Once fully implemented, the SW Montgomery Green Street has the potential to manage millions of gallons of runoff each year. However, there is a lot of variability in how"green"a street really is and all green streets are not created equal. Within some streets, and as in the case of SW Montgomery, individual blocks can vary on how aggressive the green street approach is.

蒙哥马利西南绿街的各个街区可通过多种方式,实现雨水径流的可持续管理。但是,唯独这三个主要用于机动车通行的街区还可对其机动车道进行改造,完善步行设施,使之与项目区域周围的城市和绿化空间相连。此外,该廊道沿途现有的许多建筑已准备好进行再开发或再利用工作。再开发项目的实施可增强这些区域的雨水径流收集,并将雨水引至蒙哥马利西南街的景观绿化系统
Opportunities abound on all of the blocks within the SW Montgomery Green Street to manage stormwater runoff in a more sustainable way. However, the three blocks that currently carry auto traffic hold a special opportunity to transform the auto-based vernacular into an enhanced pedestrian condition that connects to urban and green spaces surrounding the project area. In addition, many of the existing buildings along the corridor are poised for redevelopment or reuse. When redevelopment does occur, there will be the potential to capture stormwater runoff from these areas and redirect it into the SW Montgomery Green Street's landscaped system.

大学校区内的步行和雨水街景重新焕发新生,显示出蒙哥马利西南绿街的巨大潜力。宽阔的步道及无路缘街道方便了各种场地设施的建设,有利于激发新装上阵的底层零售区活力。可移动的路界护柱可灵活利用,偶尔或永远关闭该街道,以禁止汽车通行。该街道及再开发建筑的雨水径流被引至雨水渠道的景观系统中。除此之外,现有天桥系统还采用了各种绿墙技术,模仿波兰西山森林的多植被层
A revitalized pedestrian and stormwater streetscape at the University Services Block illustrates the enormous potential for the SW Montgomery Green Street. The wider sidewalks and"curbless"street condition allows for various site furnishings and will help activate newly refurbished ground-floor retail. Removable bollards provide the flexibility to occasionally or permanently close the street to automobile use. Stormwater runoff from the street and redeveloped buildings is conveyed to the stormwater spine's landscape system. In addition, various green wall technologies are also applied to the existing skybridge system to mimic the multiple vegetated layers of Portland's West Hill's forests.

城市中心广场是蒙哥马利西南绿街概念规划实施改造的第二个街区。波兰州立大学重建的广场目前设有三个雨水花坛,巧妙地分布于原有的喷泉旁,从而增强了蒙哥马利西南绿街的雨水渠道元素。从广场及临近步道收集来的近8 000平方英尺(约0.07公顷)的雨水径流通过一系列排水沟流入雨水设施中。雨水通过金属低坝及花岗岩小溪从一个花坛倾泻至另一个花坛,从而构成了一种视觉享受。城市中心广场的改造使水体、植物生命及都市空间得以灵活布局,令人赏心悦目
The Urban Center Plaza was the second block to undergo a retrofit under the SW Montgomery Green Street Concept Plan. Portland State University's rebuilt plaza now features three stormwater planters strategically placed next to the original water fountains to reinforce the stormwater spine element of the SW Montgomery Green Street. Approximately 8,000 square feet of runoff is captured from the plaza and adjacent sidewalks and is conveyed through a series of trench drains into the stormwater facilities. A visual showcase, the stormwater cascades from planter to planter through metal weirs and granite rills. The Urban Center Plaza retrofit provides a delightful display of water, plant life, and urban space.

波兰州立大学的史密斯纪念馆学生会广场是蒙哥马利西南绿街概念项目九个街景楼群中最先实施建设的楼群。整个广场空间经过重新分类改造,使雨水径流以片流形式流入雨水渠道。该渠道为5英尺(约1.5米)宽,与建筑立面平行,极为醒目。一系列精工细作的金属桥梁使行人得以跨越雨水渠道,见证桥下的潺潺流水。大学天桥系统的雨水径流也被引流至雨水花坛中,并随之渗入地下。该广场为蒙哥马利西南绿街其他街区的建设提供了成功的先例
Portland State University's Smith Memorial Student Union Plaza was the first of nine streetscape blocks to implement the SW Montgomery Green Street Concept Plan. The entire plaza space was re-graded to allow runoff to sheet flow into the prominent 5-foot wide stormwater spine running parallel to the building facades. A series of sleek metal bridges allow pedestrians to cross over the stormwater spine, but also allow water to flow underneath them. Runoff from the university's skybridge system is also directed into stormwater planters where it can infiltrate into the ground. The plaza has set a successful precedent for implementing the remaining blocks of the SW Montgomery Green Street.

俄勒冈州可持续发展中心是该国首个市中心高层建筑,其设计旨在满足卡斯卡迪亚地区环保建筑委员所设生态建筑挑战的苛刻先决条件。蒙哥马利西南绿街及俄勒冈州可持续发展中心已通过景观设计师的规划,成为雨水的综合管理区。第五级绿街状况有效地模糊了公共与私人雨水管理设施之间的界线,并将成为蒙哥马利西南绿街沿路最大胆的可持续场地发展范例。该项目已按计划于2013年开工建设
The Oregon Sustainability Center is the nation's first downtown high-rise building site designed to meet the rigorous prerequisites of the Cascadia Region Green Building Council's Living Building Challenge. The SW Montgomery Green Street and the Oregon Sustainability Center sites have been planned by the Landscape Architect to function as one integrated space for stormwater management. This Level 5 Green Street condition effectively blurs the line between public and private stormwater management and will be the boldest example of sustainable site development along the SW Montgomery Green Street corridor. The project is slated to be built in 2013.

Project Statement
The SW Montgomery Green Street demonstrates an emerging new urban street plan for which Portland is receiving national and international recognition. This multi-block plan incorporates a variety of green infrastructure and alternative transportation strategies throughout this emerging downtown neighborhood. The Southwest Montgomery Green Street is considered to be Portland's boldest and most innovative downtown green street project to date.
 
 
Project Narrative
Through a collaborative effort, the Portland Development Commission (PDC), Portland's Bureau of Environmental Services (BES) Portland State University (PSU), and Gerding Edlen Development, are pursuing a 9-block plan that incorporates a variety of sustainable stormwater management strategies from SW 11th Avenue east to Pettygrove Park via SW Montgomery Street. The Portland Central City University District Plan emphasizes the development of this neighborhood as an area where University uses mesh with City of Portland goals and designates SW Montgomery Street as a key east/west pedestrian corridor. Simultaneous multi-block development and redevelopment along SW Montgomery Street will dramatically build upon the long-term efforts advanced by the City, PSU, private developers, and businesses over the past four decades. The strategic convergence of these elements will successfully activate the neighborhood, enhance the pedestrian experience, foster sustainability, and continue to build a community culture. The SW Montgomery Green Street Plan demonstrates how, in even the most ultra-urban conditions, downtown streets can be planned and retrofitted not only to fully manage stormwater runoff but to also create, integrate, and preserve vibrant pedestrian spaces. The landscape architect was asked to take the primary role creating a highly integrated and pedestrian-oriented urban streetscape vision that incorporates a variety of green infrastructure strategies along the corridor including stormwater swales, planters, green walls, green roofs, artful stormwater conveyance, and a definitive "curbless" street design.
General Project Goals
• The SW Montgomery Green Street Plan aims to achieve many goals for the surrounding project area. Several general goals were identified by the project team early in the planning process, including:
• Enhancing Portland's current reputation as an incubator for collaborative and innovative sustainable design and development,
• Developing a model for sustainable practices by incorporating sustainable stormwater management approaches into the site design and celebrating all the elements of a vibrant urban environment,
• Creating a primary means of connectivity among amenities such as the University, fountains, parks, auditoriums, museums, theaters, and shopping; within walking distance of many central city business district jobs, also connect to the greater metropolitan area via the streetcar, future light rail, and numerous transit mall bus lines,
• Expanding the Urban Center Plaza's success as an active city plaza and let that success extend throughout the entire project corridor,
• Incorporating the vision to connect the West Hills with the Willamette River along SW Montgomery Street, and:
• Using the SW Montgomery Green Street to connect the overall area to an Eco-district.
Specific Green Street Goals
Along with the general goals outline above, the landscape architect was tasked to help achieve specific green street design goals for the SW Montgomery project corridor, including:
• Create wider sidewalks and "curbless" street conditions that allow for various site furnishings adjacent to ground floor retail areas. Blocks that carry auto traffic should have active retail with one lane of traffic and one lane of parking with the option to close for pedestrian-only special events,
• Introduce a visually continuous landscaped element that acts as a "stormwater spine" or common thread through multiple blocks and creates a "green" east/west connection through downtown and the Portland State University district,
• Integrate right-of-way green street design with adjacent developments including the planned Oregon Sustainability Center. Explore the potential of creating shared stormwater planters to accept both street and building rooftop runoff, and:
• Retrofit green street elements along the project corridor, while honoring the character found particularly at the South Park Blocks, Urban Center Plaza, and Pettygrove Park.
Project Analysis and Implementation
To fully realize the plan for the SW Montgomery Green Street, the landscape architect was asked to study the project's site character, determine the project's overall stormwater management goals, investigate and respond to the site's constraints, determine how bold of a green street is possible, and analyze the different modes of circulation throughout the neighborhood. This analysis provided the opportunity for 1.8 million gallons of stormwater runoff to be managed through the street's "stormwater spine," the potential for a significant transportation mode shift from auto-infrastructure to people-infrastructure, and the ability to have the street itself catalyze sustainable private redevelopment along the SW Montgomery Green Street corridor. The final product of these analyses is the creation of the SW Montgomery Green Street Plan which has proven to be highly implementable both in the near and long-term.
The SW Montgomery Green Street Plan is being implemented in multiple phases. Two blocks of the plan, the Smith Memorial Student Union Plaza and the Urban Center Plaza Retrofit, have been successfully completed by the landscape architect's design team. Two additional blocks are targeted for implementation within the next two years, including the proposed Oregon Sustainability Center- Portland's most technologically advanced, state-of-the-art green building site that aims to meet the rigorous criteria of the Living Building Challenge. With the strategic convergence of various partners and continued planning and implementation efforts, the SW Montgomery Green Street corridor will successfully activate the neighborhood and foster sustainability as a relationship between academic, residential, and business communities. This project's implementation will serve as a new concept for street planning and a place-making model for other downtown streetscape projects in Portland and beyond.
