on the Transformative Impact of Landscape Architecture
Across Tennessee, HargreavesJones has transformed inaccessible, polluted industrial riverfronts into rich, multifaceted parks. What has the investment in the revitalization of Tennessee’s riverfronts meant to you? What trends are you seeing in Tennessee with public space more broadly?
It's not just Nashville and Tennessee. We have found mid-tier cities are not just thinking about their post-industrial riverfronts, but also their place in the market and their ability to draw businesses and people. They’re more open to transformation, so that’s how we ended up doing major riverfront projects in cities such as Louisville, Kentucky; Chattanooga and Nashville, Tennessee; and Davenport, Iowa.
The steel industry left the riverfront in Nashville in a post-industrial state. The community embraced the idea of truly making something completely different out of their riverfront because they had nothing. It's harder to come into cities like Los Angeles, New York City, or San Francisco with such sweeping transformations. In Nashville, Chattanooga, and Louisville, landscape architects can design signature waterfront experiences, address the dynamics of rivers, and restore ecosystems that can be a healthy part of a river system.
In Nashville, your firm designed the 6.5-acre Cumberland Park as part of a broader riverfront revitalization plan. The park is a model of sustainability and resilience, reuses a bridge structure, sources geothermal, preserves the flood plain, captures and reuses a million gallons of stormwater, remediates toxic soils, and improves biodiversity. How did you make all the pieces fit together?
It was so evident, the opportunities were there. Just focusing on stormwater for a minute: there were walls beneath the gantry structure, so the first thing we said was, “don’t take this gantry structure down, it’s beautiful. Not only will we build a bridge to it and let it become an overlook, we'll also leave the heavy-duty concrete retaining walls below it. Let’s use the space to create an outlet for stormwater from the site and from the two bridges into a cistern.” We created a cistern that has an open air top so it’s actually quite beautiful to look down on, like a reflecting pool. You kind of want to jump in. Then there’s the river, so in flood times, it spills over to the river.
Bio-remediation is just dealing with the soil, which is the case on almost every project we do. We have to either bake or bury and cap soils, depending on the toxic substances and conditions. Geothermal became part of the building, an existing piece of infrastructure from the steel industry, which was then retrofitted by architects on our team to become the stair tower, concessions booth, and park office building. Even the toilets are mindfully designed for low water usage. With science, there are all these opportunities.
In Chattanooga, Tennessee, your firm also designed a 23.5-acre Renaissance Park, which transformed a former industrial site into a wetland park, and the 21st Century Waterfront Park, which reconnects the city to its riverfront and has led to $1 billion in new residential and retail development nearby. How do you design for multiple needs at once -- social life, economic development, equitable access, and environmental restoration? How do you prioritize?
As landscape architects, that’s our job. That is the beauty of landscape architecture. We are not just doing the science; it’s not just a matrix of solving problems. We also create places people will love. The result of that will be economic investment and stewardship. If we don’t make places people love, they won’t be taken care of.
We create social and economic change around these projects, but at the same time we’re providing something to the neighborhood around these projects. We’re revitalizing these neighborhoods.
We don’t think we can just restore nature. We can’t just make form, design, and feel good about that. We have to do both those things and think about what is fiscally responsible because that’s what is ultimately going to give a project its long life.
Another significant new riverfront park in the South that HargreavesJones designed is Crescent Park along the Mississippi River in New Orleans. By reusing surplus wharfs and derelict railroad sites a new public space was formed that celebrates the city’s infrastructural legacy instead of wiping it. What is the best way to tell landscape stories using the past? What are the other benefits of adapting and reusing legacy infrastructure?
Sometimes adaptive reuse -- reinventing and reinterpreting remnants -- makes your budget spread farther. An early groundbreaking project in this regard was Richard Haag’s Gas Works Park in Seattle. He left the old structures as is and created a green space around them.
But we’re taking it further now. There are remnants, but we interpret them in new ways. We aren’t just saving the rail tracks, we’re making gardens that follow the path of those rail tracks. We’re not strictly preserving, we’re amplifying through reinterpretation and twisting things that makes you see the infrastructure in a new way.
The transformation of Oklahoma City has been accelerated by the 70-acre Scissortail Park, the grand new central park that will connect the city to its waterfront and realize its core to shore plan. How did your firm's design for the park advance the plan?
We were really interested in the transition from urban to river and making that legible in the park design. Rather than thinking of the park as one piece, we thought of it as a gradation of landscape types so it progresses quite a lot as you move toward the river in terms of its design, landscape, and materials. Of course, there are some consistencies. The promenade and the lighting of the promenade goes all the way from core to shore, but the landscapes and the planting around it evolve quite a bit, as do some of the uses.
We wanted to accentuate that experience of moving toward the river, so that as a visitor, you become aware you’re entering a landscape that gets wilder and wetter. There’s an upper park and lower park, and they’re linked by the fabulous Skydance Bridge designed by Hans Butzer, who was part of our team. Before, visitors couldn’t see the river because of the levy along the river, so we created a high point at the southern terminus of the project, closest to the river.
We also designed the park to respond to climate change. That area of the city floods, so the design of the park accommodates floodwater with a big lake. The lake is also a holding basin for irrigation.
