休斯顿河湾绿道规划设计解读

1、项目陈述PROJECTSTATEMENT河湾之城？放眼看去，休斯顿地区扩张性的城市发展，超级运输系统与占据大量空间的工业区使得这座历史名城的绰号不过只是一句欺骗性的空话。建立在ArthurComeyi93i年的报告“休斯顿，实验性城市发展计划”的基础上，近期完成的河湾绿道总体规划创造了一条300英里长的线性公园系统，将哈里斯县10条主要的水道流域范围内的190万城市居民连接起来，并将带来包括经济、环境与身体及精神健康方面的多项收益。据来自德克萨斯农工大学的JohnCrompton教授估算，其每年的效益将超过1.17亿美元。从源头到汇流处，河湾绿道的每一部分都是基于生态遗产多样性以及保证市民生活

2、品质的前提下建立的。在2012年经选举人投票通过，1亿美元的公共资金以及1.05亿元美金的私人投资将全部被用于第一阶段巧0英里长的绿道建设。最终的建设成果展现了区域的特色，为市民所津津乐道。BayouCity?Atfirstglance,theHoustonregionssprawlingdevelopmentfootprint,hyperengineeredtransportationsystems,andmassiveindustrialcomplexesseemtorenderthishistoriccitynicknamemoredelusionthanreality.BasedonA

8、近期完成的河湾绿道总体规划创造了一条300英里长的线性公园系统，将哈里斯县10条主要的水道流域范围内的190万城市居民连接起来，并将带来包括经济、环境与身体及精神健康方面的多项收益。据来自德克萨斯农工大学的JohnCrompton教授估算,其每年的效益将超过1.17亿美元。从源头到汇流处，河湾绿道的每一部分都是基于生态遗产多样性以及保证市民生活品质的前提下建立的。最终的建设成果展现了区域的特色，为市民所津津乐道。断开的连接人们对休斯敦水道的认知与态度是不断地在变化。讽刺的是，与河口区域缓慢变化的自然类似，休斯顿己经耗费了近百年来认识和积极面对标志性的自然系统带来的益处。在19世纪快速城镇化之前

9、，东部富饶的山地和山地森林内蕴含着丰富的水资源向着西侧流淌，最终汇入沿海的广阔草原。这些生态系统能够适应该地区的气候，包括不时的洪涝，为区域带来了活力。休斯顿建于1836年，丰富的自然资源带来了人口、城市与商业的迅速发展。从19世纪中叶到20世纪初期，该地区的居民试图通过疏浚河道，采伐木材以及发展海湾沿岸商业的方式来激发水道的潜力。随着河溪之城的人口增长与城市化进程的加速，洪水的破坏性也随之增加。因此对大部分人而言，河流不是资产而是累赘。然而，一些人还是认识到这些河流资源的巨大潜力。在1913年规划师ArthurComey提岀了将河流转变为一个线性公园系统的方案。他在报告“休斯顿，实验性城市发

10、展计划”中，建议修建一个河湾公园系统为不断增长的人口提供更好的环境与生态服务，提高连接各城镇河流周边的开放空间质量。这一河湾绿道的前身没有得到大家的支持。为了减少洪水泛滥，许多城市的河道在世纪中叶被硬化或被加以河渠。同时由于道路的铺设，延绵数千英里的高速公路与街道将许多原本联系在一起的水道河流截断分离。直到20世纪70年代，保护河流系统的提议再次获得了舆论的支持。到2012年，支持河道系统的声音推动了休斯顿最大的公园建设的决策。最终，城市重新与其自然遗产融为一体，在沿线“为休斯顿创建均匀分布的公园地带”。重新连接规划方案经过了百年时间和主要系统重组之后，规划师面对的是一个极大地转变和扩展的景观

11、问题。在总体规划进程的初期，规划团队研究了河口之城的历史，以及当地当下和未来的发展趋势，并基于直升机空中调研，数百英里的徒步以及几百万字节的地理数据创建了详细的数据库。总体规划在当今时代展示了多种可能性，实现了Comey的理想并满足了社区的愿望。成果是一个综合性的研究：展现了主次道路网络确定了步道口，自行车共享机会以及亲水点确认具有可替代性的交通策略建议临近的社区相互连接确定洪泛滞留与缓和区域描述自然景观类型的修复机会提岀粗略的设计指南量化相关维护要求和相关成本项目机遇河湾绿道解决了全国第四大城市市民日常生活中无数的健康，安全以及福利问题。休斯顿一度被评为全国最不健康、公园空间最匮乏、经济最分

12、裂、城市扩张以及发展最快的城市之一，面临着巨大的社会问题。休斯顿的面积早己是大部分北美城市面积的5倍，且到2035年人口预计将翻倍。河湾绿道正在通过创造人与自然以及不同人群的连接，来塑造城市发展结构。虽然休斯顿拥有明确的公园空间和步行系统，但是由于城市没有分区，因此历来无法有效地建设足够的开放空间并连接它们。根据公共土地信托数据显示，在公园空间排名中，休斯顿在75个主要都市区中仅排第58。而增加城市开放空间的关键在于区域洪泛区。相对平坦的地形，密集的降雨以及城市化的流域创造了广阔的管辖洪泛区。由于发展限制以及哈里斯县洪水控制区的监管控制，大量的土地被作为不能使用的绿地或空地。河湾绿道规划建议充

13、分利用这些空间在1.5英里范围内为6/10的休斯顿人创造步道走廊，新公园以及洪水缓解设施。由此产生的网络绵延超过300英里，将4000英亩新的土地与街区、学校、教堂以及其他社区资产连接到一起。汇水区将包括如今被物理阻挡或管辖地区，增加缓解洪水的机会，帮助重新连接当前分散的生态。在这些河流廊道中形成的洪水缓解设施将每年有1%的可能被洪水淹没，但在其余的时间中都将为居民提供实用的休闲娱乐空间。由于尺度巨大，多数廊道需要被设计成低维护的功能性生态系统。精心维护的区域仅岀现在步道尽头周边与高度城市化的区域，而沿着绿道边缘、大面积的洪水滞留区和自然公园内则是低维护草地以及再造林区。项目实施休斯顿市除主城

14、区外，还拥有4个县界，140个市政公用区，88个超级街区，40个管理区以及23个税收再投资区，因此该项目跨越多个管辖区，遇到各种实施障碍。或许迄今为止最大的成功是公众对实现这一愿景的高度热情。作为实施的第一步，设计团队引入了大胆的举措以为连接城市内所有缺失的连接筹集资金。这项名为“河湾绿道2020”的举措在整体规划策略中至关重要。而作为比较，拥有全国第二大绿地系统的波特兰的绿道总长不过仅为“河湾绿道2020-150英里多用途绿道的一半。2012年，河湾绿道在城市策略公投中获得了最高的支持率，选举人投票通过将1亿美元的公共资金以及1.05亿元美金的私人投资用作绿道建设。目前，河湾绿道项目继续向建

15、设迈进。业主利用该方案，从整体性的项目规划与分析中拆分岀独立的项目片段，并招募当地公司深化建设。当招募完成后，每个项目则将朝施工图纸绘制、审批和招投标继续推进。到目前为止，一些小的项目片段已经落成，并受到了市民的欢迎，而其余部分也向着建造程序稳步推进。总结公园对城市有着极为重要的意义。河湾绿道项目使得不同尺度开放空间的作用发挥到极致，并提升了生活的品质。简单的概念，复杂的执行，创造了一个新的休斯顿传奇。BAYOUGREENWAYS$：RECONNECTINGHOUSTONWITHITS亍ONCEFORGOTTENBAYOUS根据ArthurComeyi93i年的报告，这个愿景规划的制定己历经百

16、年。而在这百年中，城市的发展、对环境的忽略以及碎片化的发展模式己经改变了Comey当初的基线。河湾绿道项目直观的将河溪系统与Comey的愿景重新连接在一起，创造了休斯顿传奇。BASEDONARTHURCOMEYS1913REPORT,THEVISIONARYPLANHASBEENOVER100YEARSINTHEMAKING.ACENTURYOFCITYGROWTH,NEGLECT,ANDFRAGMENTATIONHAVECHANGEDCOMEYSBASELINE.BAYOUGREENWAYSINTUITIVELYRECONNECTSTHEBAYOUSYSTEMSANDHISVISIONRES
