SWA: 这个花费1500万美元的项目是休斯顿市对公共绿地进行过的最大投资之一，历史性的由公共私营合作为振兴休斯顿市中心的城市滨水区而建。SWA被聘请对这个长达两英里且地块环境极具挑战性的项目进行前期总体规划和后期完整的景观服务，在规划中，对高架桥、公用设备、陡峭的山坡、受限的访问和洪水海拔线的考虑至关重要。该项目将曾经被忽视的对行人来说十分难看而且不利于防洪的“眼中钉”转变成了距离城市公园3000纵尺，可以通向休斯顿市中心，甚至在休斯顿内城增添了20英亩公园空间的景观步道。该项目在设计中突出了坡度和缓的河岸、广袤的原生态景观、步行道和自行车道、公共艺术、极富戏剧性的艺术照明设施。新设立12个街区—河口的通道、楼梯和坡道能使游人更方便找到河口、自北向南的人行天桥、导引服务和解译标识。

SWA: One of the largest investments in public parkland ever carried out by the City of Houston, this $15 million project was the result of an historic public/private partnership to revitalize Houston’s downtown urban waterfront. SWA was retained to create a master plan and subsequent full landscape architectural services through two miles of some of the most challenging urban conditions: overhead freeways and utilities, steep slopes, limited access and critical flood water elevations. The project converts a once neglected eyesore—intimidating to pedestrians and detrimental to flood control efforts—into 3,000 linear feet of urban parkland providing a gateway to downtown Houston and adding over 20 acres of park space to Houston’s inner city. The project features naturalization of gently sloping banks, extensive native landscaping, hike and bike trails, public art, dramatic artistic lighting, 12 new street-to-bayou entryways, stairs and ramps reconnecting people to the bayou, a major north-to-south pedestrian bridge, way-finding, and interpretive signage.

河口堤岸上的自然河道和天然土壤使用填石铁笼、14000吨岩石和再生混凝土进行锚定加固。杂草和其他侵入性植物被逐步清理，取而代之的是近300000棵植物(多为本地多年生花卉、地被植物和树木)。照明系统是按照月亮圆缺亏满的变化来设置灯光的，从新月时散发蓝色灯光开始，逐渐变得洁白如满月。所有照明设施、植物种植和人行道设计都是为了抵抗河口周期性爆发的洪水。现在的水道中生活着鸭子、苍鹭、海龟和鱼等各种动物。美国陆军工兵部队现有的HEC模型确保本次改造对泄洪设施不会造成危害。这个河湾步道成为休斯顿市的新地标，对商业、休闲和文化活动以及居民的活力产生了有利的影响。

The natural channel and the soil along the banks of the bayou were stabilized through the use of gabions and the anchoring of 14,000 tons of rock and recycled concrete. Weeds and other invasive plants were replaced by nearly 300,000 plants (including native perennials, groundcover and trees). The lighting system provides glowing orbs that follow the monthly phases of the moon; lights are blue when the new moon occurs and gradually shift to white as the full moon emerges. All lighting, plantings, and walkways were designed to withstand the natural, periodic flooding of the bayou. The waterway now teems with ducks, herons, turtles, and fish. The Army Corps of Engineers’ existing HEC model was used to ensure that floodwater conveyance would not be compromised by the improvements. This new public space provides national prominence conducive to commercial, recreational, cultural, and civic vitality.
