项目陈述

Project Statement

7号码头公园公园与休闲码头汇聚了本地居民、游客与野生动植物，打造出一个富有趣味的交汇场所，其设计灵感源自水流的起伏变化。焕新的滨水空间邀请人们亲近水岸，通过开放的互动体验和对本地生态的融入，营造轻松愉悦的氛围。作为这条一英里长综合开发项目的核心，设计不仅呼应了水域与造船工艺的意象，还构建了一套能够过滤雨水、修复自然栖息地的生态系统。在华盛顿特区经历了数代人与水疏离的历史后，这一场所的广受欢迎，充分印证了宜人社区空间的深远影响，以及人们对陆地与水域交汇之地的本能向往。

The Wharf’s 7th Street Park and Recreation Pier draws a diverse mix of locals, visitors, and wildlife to a playful meeting point: a site that conceptually reflects the rise and fall of rolling current. A reimagined waterfront invites people to the water’s edge, uplifting spirits through accessible play and immersion in the local ecosystem. At the center of a mile long mixed-use development, the project evokes imagery of both water and shipbuilding and an ecology that filters stormwater and regenerates the natural habitat. After generations of limited water access in Washington, D.C., its resounding popularity reveals the impact of building an inviting community place and the innate desire to occupy the intersection of land and water.

项目说明

Project Narrative

7号码头公园与休闲码头位于华府码头的核心地带，这是一个占地24英亩的活力滨水开发项目，沿华盛顿水道展开。项目通过7号码头西南延伸段将城市与水岸紧密相连，响应了国家首都规划委员会关于连接华盛顿市中心、国家广场与周边河流的愿景。该地块承载着丰富的水岸历史，但公共水域通行权曾长期受限，如今，这一空间重新开放，为城市居民和游客提供了亲水体验。

景观设计团队以“健康滨水城区”的愿景为指引，使城市与水岸深度融合。项目采用以社区为导向的设计方法，利用趣味元素吸引多元人群，在自然水岸环境中打造独特的公共体验。设计团队结合手绘与Rhino、Grasshopper等3D建模工具，精细推敲场地坡度与无障碍通行，最终呈现出灵感源自水波律动的创新码头设计。

公园作为缅因大道与水岸之间的绿色过渡地带，乔木林立，树荫斑驳，坡地草坪成为锻炼、日光浴及聚会的理想场所。环绕公园的街道以步行优先，中央设有椭圆形草坪，由北端高点缓缓倾斜至南端雨水花园，园内原生湿地植物可净化场地雨水，形成生态友好的排水系统。

高架遮阳结构提供休憩空间，并设有俯瞰水面的观景平台，与互动喷泉相邻。码头呈新月形，延续公园步道的流线感，并由上层固定平台与下层浮动码头组成。码头北端连接挡土墙，中部微微下沉形成“鞍部”，随后再度升高至终点。“鞍部”区域设有金属栈桥通往浮动码头，为皮划艇租赁提供无障碍通道。码头甲板采用Kebony木材，这是一种经过环保热处理工艺改良的可持续木材。创新施工工艺使木材能够弯曲成流畅的曲面，塑造了起伏的坡道和攀爬墙。码头西侧设有木质长椅、嵌入抛物线框架的定制秋千，以及通向14英尺高定制火炬雕塑（“火炬”）的步道。这座雕塑每晚点燃，成为一年四季的聚集地标。

该项目通过优化生态环境，助力华府码头的可持续发展愿景。码头东侧的漂浮湿地有助于消散并净化来自公园地下90英寸雨水排放口的径流，恢复场地原生生态，并为水生生物与水鸟提供重要的栖息地。

项目的跨世代、包容性设计，使人们在坡面上漫步、滑行，或与朋友共乘秋千时感受到纯粹的欢乐，为城市提供了一个急需的社区活动空间。这里充满活力与惊喜，让人们在与彼此互动的同时，也重新感知水岸的魅力。

Project Narrative

The 7thStreet Park and Recreation Pier is situated at the heart of the District Wharf, a vibrant 24-acre development on the Washington Channel in DC. The project connects the city to the water at the urban street grid extension of 7thStreet, SW. This extension supports the National Capital Planning Commission’s vision to connect downtown D.C. and the National Mall to its rivers. The site has a storied history with the water’s edge, where public access to the water was restricted for generations.

The Landscape Architect brought the client’s vision of a healthy, waterfront district to life, connecting the water to the city. In an intensive, community-driven design effort, the design uses playful elements to draw a diverse community together in a fresh natural setting at the water’s edge. Design methods included hand sketching and 3D programs like Rhino and Grasshopper to investigate the subtleties of site grading and universal accessibility with sculptural built form. The result is a novel pier design that evokes the soft, undulating geometries of gentle waves.

The Park is a green threshold between Maine Avenue and the water. A resilient mix of canopy trees offers dappled light on a sloped lawn, used for exercise, sunning, and informal gathering. The shared street around the park prioritizes pedestrians, and at its center is an oval lawn that slopes from a high point at its northern end to a rain garden with riparian planting at the southern end to cleanse the site’s stormwater.

A tall shade structure is a place to pause with an overlook to the water adjacent to an interactive fountain. The pier is crescent shaped, extending the pedestrian movement of the park’s curvilinear pathways to the water. The pier consists of an upper, undulating fixed level and a lower floating dock. The pier meets the bulkhead at its northern end and descends into a saddle at the midpoint, before rising again to its upper terminus. The saddle serves as a point to reach the water, with a metal gangway that leads to the lower floating dock for accessible kayak rental. The decking material is Kebony, which uses an environmentally friendly process that thermally modifies sustainable softwood. An innovative installation made it possible to bend the wood into a series of radii, creating the sweeping sloped surfaces and climbing wall. The pier’s western side has wooden benches, custom swings set in parabolic frames, and light fixtures that lead to a 14 - foot - high custom fire sculpture affectionately named, the Torch, serving as a nightly beacon attracting people in all seasons.

This project supports the Wharf’s vision for a sustainable neighborhood and waterways by improving the surrounding habitat. Floating wetlands anchored to the east of the pier help dissipate and cleanse water from an existing 90” stormwater outfall that runs under the park and exits at the bulkhead beneath the overlook. Native riparian plantings recall the site’s ecological roots and provide a juvenile habitat for both aquatic organisms and various waterfowl.

The intergenerational and equitable design elicits joy from strolling and sliding on the sloped surfaces or swinging with friends, comfortable for all who visit as a much-needed place of community gathering and events. This project is lively and unexpected, helping people see each other and the environment around them anew.
