—2014ASLA分析与规划专业奖评语

“This project highlights the powerful potential of landscape architects to lead groundbreaking design and planning processes for urban neighborhoods that engage across scales, from the stormwater system to the transit hub. The thoughtful integration of systems and strategies reveals the productive approach to eco-district thinking, setting the bar for projects far and wide. The project set no boundaries by addressing everything from the storm water overflow to the economic potential of development, revealing the vision of the landscape architects to imagine, design, and produce better cities for our future.”– 2014 Awards Jury

Zidell Yards场地是美国俄勒冈州波特兰市五个试点生态区之一。景观设计师带头组建一个合作工作室，致力于制定三个不同的方案。以下三个方案均采用绿色基础设施，融入过滤和地表引流系统，最终远超暴雨雨水管理的标准，完成了极具创意的棕地修复方案，为社区带来多重效益。

The Zidell Yards site was selected as one of five pilot eco-districts in Portland, Oregon.

The landscape architect led a collaborative, workshop-driven planning process to develop three distinct scenarios.

The following three scenarios apply green infrastructure solutions that capitalize on infiltration and surface conveyance with the goal of exceeding existing regulatory requirements for stormwater management and providing creative brownfield remediation solutions with multiple community benefits.

▲ 总体规划：Zidell街区占地33英亩，代表了波特兰市最大的棕地修复和二次开发场地之一。此项目是波特兰市首个完整而复杂地整合了区域规模的绿色基础设施。

Site Plan: The 33-acre Zidell site represents one of the largest brownfield remediation and redevelopment sites within Portland. This project offers the first holistic and comprehensive opportunity in the City of Portland to integrate green infrastructure at a district scale.

项目描述

占地33英亩的Zidell Yards场地，坐落于美国俄勒冈州波特兰市最大的棕地地带之一，项目针对场地修复和再开发提出绿色基础设施的解决方案。目标在于为棕地的二次开发提供综合性的绿色基础设施解决方案。

为了成功地完成项目，设计团队列出了以下目标清单：针对棕地修复独特的场地环境提出可变通的灵活解决方案

支持环境保护署为绿色基础设施达成的战略规划

设计当前暴雨雨水可持续管理技术

探索一系列绿色基础设施理念

最小化或消除新建河口管道的需求

设计价值

绿色基础设施的设计原则并不局限于棕地场地的环境，而是能够转化进新开发和二次开发以及填充场景里。每个场景方案提供了切实可行的绿色基础设施解决方法，包括公共空间和私人领地，每个元素都能混搭进整个场地里，同时适应新型的开发项目。

项目因为较高的可见性和市民强烈的参与意愿以及全市范围内暴雨雨水管理的示范意义，受到了各个市属管理机构的大力支持，甚至包括市政官员。Zidell Yards区是滨水区的理想之地，将成为大规模换乘活动的枢纽，包括新型轻轨线路和站点、波特兰有轨电车的延伸段以及连接5号州际公路和住宅小区的新步行桥。Zidell Yards区项目成为高可见度、多效益暴雨雨水管理的创新示范案例，那儿的居民和游客能够乐活每一天。这样的努力不仅见于广泛对话的初始，还延伸至设计团队对于绿色基础设施和棕地二次开发的研究和运用里。随着全美越来越多工业旧址的二次开发，设计群体也开始意识到各种绿色基础设施的潜力和局限，继而能够测试创新的暴雨雨水解决方案是否能够运用进因污染而具有局限性的区域里。

由于历史工业土地的使用，Zidell Yards区的场地和附近河流的沉积物受到了污染并列入俄勒冈州环境质量部门的自发清洁项目里。场地于2012年得到修复。

As a result of historical industrial land uses, the Zidell Yards site and adjacent river sediments became contaminated and were entered into Oregon’s Department of Environmental Quality (DEQ) Voluntary Cleanup Program. The site was remediated in 2012.

▲ 环境：周边的各项因素推进了场地的动态开发，比如毗邻波特兰市中心、南部滨水区的近期开发、俄勒冈健康与科学大学的扩建、连接轻轨与北部的新桥枢纽。

Context: The site is a dynamic development location catalyzed by its adjacency to downtown Portland, recent development of the South Waterfront District, expansion of Oregon Health Sciences University, and the new light-rail bridge terminus to the north.
