项目陈述
PROJECT STATEMENT

位于美国康涅狄格州斯坦福市的弥尔河公园曾经是被人为开挖、污染严重的河岸地区，而今却是一个郁郁葱葱的、非常有活力的城市空间，并彻底改善了城市生态和社会结构。景观设计团队同工程师和生态学家密切合作，通过重塑河道和引进数百种原生植物，打造出一个一举两得的景观项目：一方面复苏了水陆栖息地的活力，另一方面降低了城市洪水风险。公园取得的变革性效果将生态的可持续性融入到社会可持续性及公共正义之中。一个世纪以来，沿河步行道第一次打通了前往河岸的通道，将富有生命力的景观和周围街区重新联系在一起。这一设计为迫切需要公园空间的人们提供娱乐场所，多功能的“大草坪和观景平台”为大型公共活动提供场地。作为定义活跃的城市生活的典范，弥尔河公园是住宅、企业、商业开发项目增长的催化剂，为经济的可持续性发展创造条件。

Formerly a polluted, derelict riverfront, Mill River Park and Greenway is now a verdant, animated civic space that mends the ecological and social fabric of downtown Stamford, Connecticut. Working closely with engineers and ecologists, the team conceived of a landscape designed to revitalize aquatic and terrestrial habitats and reduce flooding by restoring the channelized river’s edge and introducing hundreds of new native plants. The transformative effect of this park builds on ecological sustainability into social sustainability and social justice. A series of walking paths along the river reconnect neighborhoods to this vibrant landscape, granting access to the river’s edge for the first time in a century. The design provides much needed park space for active and passive recreation and a flexible “Great Lawn and Overlook” for large programmed events. A model for redefining active urban life, the park is a catalyst for residential, corporate and commercial growth and economic sustainability.

项目说明
PROJECT NARRATIVE

康涅狄格州斯坦福市内的弥尔河在筑坝、河渠开挖、杂物堆放、淤泥堆积等等恶性作用下，大大增加了市区洪水的风险。为了降低这一风险，美军陆军工程部和斯坦福市执行了一项景观工程：移除两侧的混凝土堤坝，让弥尔河自17世纪以来第一次得以自由地流淌。这一绿色基建工程不仅恢复了沿河的栖息地，降低了城市洪水风险，还借机开发出周边的公园空间，将市区同河岸结为一体，实现了区块的整体复兴。

近100年来，斯坦福市一直梦想在市区打造一座中央公园，并沿着历史悠久的弥尔河河岸建设一条绿色的廊道。在联邦政府、州政府、市政府联手的财政支持下，设计团队得以为该地区制定总体规划，并对一座28英亩的公园和一条3英里长的绿色廊道进行景观设计。景观设计团队同陆军工程部紧密合作，负责该区域总体规划的设计和实施，这一规划将持续性地促进栖息地的生长，经过近十年的时间重新连接起城市与自然。这一工程的实现要感谢传奇的城市规划师Herbert Swan。在1929年，Swan追随Fredrick Law Olmsted的愿景，“设计出大都市中的郊野”，将目光投注到在城市环境中塑造公园空间的重要性上。

弥尔河绿色廊道总体规划的生态组成要素之一是增加该地区的生物多样性，即通过移除大坝，引入多样化的栖息物种为原生的野生动物群体提供支持。与生物栖息生态学家紧密合作，设计师通过塑造河滩、集水区和蜿蜒的河道来模拟自然的河流形态。原生树木、灌木、草类构成的稳定的植被组合，被用以固定河岸土壤，同时为野生动物提供食物、栖息地和筑巢的场所。被重新引入的洪泛区在城市的中心创造出重要的盐沼栖息地，为从盐水迁徙到淡水中溯河产卵的鱼类提供前往集水区的通道；360年来，1200条河水青鱼第一次回到这里产卵；潮水交换效应为陆地和水域带来惊人的生物多样性。得益于多样化的河岸形态和河水深度的设计，其他物种得以在此栖息。

如今，重新分级的河岸与自然的、防护性的洪泛平原相类似，能够消除雨水对周边街道和街区带来的损害。这条曾经给附近街区带去持续性洪水威胁的河流，如今已经能够自行处理暴风雨带来的水量波动。事实上，在最近的两次飓风中，洪水对公园和周边地区并未造成严重影响。今天，蜿蜒的河流在步行道、休息区和公园设施中穿行而过，为人类和野生动物营造出平和而生机勃勃的环境。

种植的第一阶段移栽了超过400株原生树木和灌木。原生野花和草类的种子也散播在潮湿区、半潮湿区和城市高地三个不同的区域。播种后的春天，强烈的暴风雨冲走了一部分，但绝大多数种子就地生根、发芽。更重要的是，新洪泛区的效果跟设计预想的一样，对小路和河岸没有损害和侵蚀。同年第二次播种下的五颜六色的野花的种子让种植设计的效果更加丰富。野花、草类、灌木和树木的组合为陆居物种创造出全新的栖息环境。当地社区也积极融入到公园的维护中来，经过培训的志愿者在除去偶尔出现的入侵物种方面给予了很大的帮助。学生团体在这里获得原生植物的知识，并加深了对植被看护工作的理解。公园的访客将他们拍摄到的野生动物，如水獭和在地面筑巢的鸟类的照片上传到弥尔河公共网站上，这些野生动物出现在与市中心如此接近的地区是非常罕见的。从这些图片中，可以辨认出超过50余个独立的植物物种，它们在此生根生长，为野生动物提供食物和栖息地。

景观中的设计元素首先要尊重基地的历史，其次要经久耐用。摆放得当的长凳和大块的回收来的卵石，沿着小路和观景平台，为访客提供就坐休息的场所。地面铺装材料具有很好的抗洪水腐蚀性能。设计师保留了历史悠久的石墙，并将从建筑工地中挖掘出来的石头放置在景观之中，用以昭示当地的历史和地理特质。作为公园与市区相连接的典例，美洲香槐列队组成的林荫大道从城市的入口延续进来，通向为举办大型活动和沿河娱乐项目提供开放性空间的“大草坪和观景平台”。此外，设计团队还考虑到当地社区民众对樱桃树的喜爱，尽可能地将原有树木保留下来，并在施工期间倍加看护，之后将所有的老樱桃树和新树的一起，移植到通往大草坪和观景平台的小路旁。

设计还为将于未来出现的设施预留了空间，包括Steven & Alexandra Cohen喷泉和溜冰场、Brownstein / Selkowitz纪念亭、Nissen转盘、弥尔河公园凉亭以及中心公园探索园等。

自开放使用以来，社区居民常年到访弥尔河公园和绿廊，带来了几百个节目，也带来了志愿者。水路的清理和设计减少了污染和杂物堆放，更改变了人们之前随意抛扔垃圾的习惯。当地居民持续的清理工作让公园自然的美感得以维持。

关于总体规划未来阶段的实施，人们更加强烈地认识到城市与生态共生的必要性，它能让市区和周边环境成为互惠互利的存在。这一项目将成为一个永不停歇地自我再生式的景观。原生的植物和野生动物会不断地回到这里。景观设计将可持续性、娱乐性、公民参与、文化教育融入到郁郁葱葱的、具有生态多样性的环境中，使之成为为子孙后代服务的城市绿色基础设施。

Obstructed by damming, channeling, pollution debris and silt buildup, the tidal and partially brackish Mill River posed a significant flood risk to downtown Stamford, Connecticut. To mitigate this threat, the U.S. Army Corps of Engineers and the City of Stamford executed a project resulting in the removal of two concrete dams, allowing the river to flow freely for the first time since the 1600s. This green infrastructure project not only provided habitat rehabilitation and reduced risk of flooding, but an opportunity to develop surrounding park space and unite the downtown with the waterfront, offering revitalization to the area as a whole.

For nearly 100 years, Stamford had dreamed of a Central Park in the heart of its downtown and a greenway along the banks of the historic Mill River. Thanks to the funding efforts of a community collaborative of city, state, and the federal government, along with local corporations and private citizens, a design team was hired to envision a master plan and create a landscape design for a 28-acre park and 3-mile greenway. Collaborating closely with the Army Corps of Engineers, the design team was tasked with designing and implementing a master plan that would facilitate sustained habitat growth and work towards the project’s nearly decade-long mission to reconnect the city to nature. The realization of this project is a tribute to the legacy of city planner Herbert Swan who in 1929 was inspired to follow the vision of Fredrick Law Olmsted to “Plan a Metropolitan Suburb,” focusing on the importance of park space in the urban environment.

One of the ecological components of the Mill River Greenway Master Plan was to capitalize on the potential for increased biodiversity that would result from the removal of the dam, helping to create a variety of habitats to support native wildlife communities. Working closely with bio-habitat ecologists, riffles, pools and meanders were recreated to mimic the natural morphology of the river. A robust palette of native trees, shrubs, grasses, and forbs were planted to stabilize the river’s edge and to provide food, habitat and nesting places for wildlife. The reintroduced floodplain offers crucial salt marsh habitat in the heart of an urban metropolis—anadromous fish, migrating from salt to fresh water, have been granted passage to the watershed; 1,200 river herring have returned to spawn for the first time in 360 years; an open tidal exchange welcomes amazing diversity on land as well as in water. A refuge for other species resulted from the design of a variety of riparian edge conditions and water depths.

Today, the regraded river’s edge resembles a natural, protective floodplain thereby eliminating the damaging effects of stormwater in the surrounding streets and neighborhood. The river that once posed a continual threat of flooding to nearby streets, is now capable of handling the fluctuation of water volume in storm events. In fact, there was no significant damage to the park or surrounding area due to flooding during the two most recent hurricanes. Today, the meandering flow of the river winds its way through walking paths, rest areas and park amenities creating a peaceful and stimulating environment for humans and for wildlife.

In the first phase of planting, more than 400 native trees and shrubs were installed. In addition, seed mixes comprising native grasses and wildflowers were sown in three distinct zones: hydric, mesic and urban upland. The spring following seeding brought unusually strong storms that washed away some seed, but the majority of the seed germinated. More importantly, the new floodplain performed exactly as it was designed to with no damage to paths or erosion of grading. A second planned over-seeding of color blended wildflower swaths was added that year to complete the planting design. A composition of wildflowers, grasses, shrubs and trees bring an entirely new habitat environment to terrestrial species. The community is actively involved in maintaining the park and volunteers are trained to remove invasive species that pop up occasionally. Student groups are introduced to native plants and gain a critical understanding of stewardship. Visitors to the park have posted pictures of wildlife on the Mill River Collaborative’s website, such as river otters and ground nesting birds that are rarely seen this close to a bustling city center. The Mill River Collaborative has identified images of over 50 individual plant species that have germinated and continue to provide food and habitat in the park.

Elements of the design pay homage to the history of the site, and were selected for their durability. Well placed benches and large reclaimed boulders create rest areas along pathways and overlooks on the site. Paving materials were selected for their ability to withstand flooding events. Historic stone walls were restored, and local stone boulders were unearthed from a nearby construction and incorporated into the project as a celebration of local history and regional geology. A Grand Allee of yellowwood trees now proceeds from the city entrance and is an example of the park’s link to the adjacent downtown. The corridor leads to the “Great Lawn and Overlook,” a flexible open space for large events and waterfront entertainment. The design team also responded to the community’s love of historic cherry trees by saving as many as possible in a holding nursery during construction. Afterward, all were replanted along with new cherry trees lining the paths leading to the Great Lawn and Overlook.

The design holds place for future amenities that will include the Steven & Alexandra Cohen Skating Center & Fountain, Brownstein/Selkowitz Pavilion, Nissen Carousel, Mill River Park Pergola, and the Discovery Center Park Building.

Since its opening, the community has embraced Mill River Park and Greenway with year-round visitation, in addition to hundreds of programs and volunteer efforts. The design and clearance to the waterway has resulted in a drop in pollution and debris, altering previous littering habits. The community cleanup efforts continue to maintain the site’s natural beauty.

Plans to implement future phases of the master plan confirm the recognition that urban and ecological cohabitation is necessary to provide mutual benefits for the city and surrounding environment. This is a self-regenerating landscape. Native plants and wildlife continue to return to this downtown area. With a design that emphasizes sustainability, recreation, civic engagement, culture and education within an ecologically diverse and lush environment, the green infrastructure will serve the city for generations to come.
