THE PRODUCTIVE FOREST: Productive, Sustainable, and Educational Agricultural Systems

Site: Waterman Farm; Ohio State University Owned Agricultural Learning Landscape Location: Columbus, Ohio Type: Master Planning, Site Design, Agricultural Landscape, Recreation Planning, Campus Planning, Ecological Design Tools: AutoCAD, Adobe Illustrator, Adobe InDesign, Adobe Photoshop, Rhinoceros 3D Team: Yiran Yang Taking into consideration the history of agricultural and forested landscapes in the United States, along with the ever-growing climate crisis, this project aims to utilize the Green New Deal as a beginning framework for re-imaging agricultural systems in the United States. The Productive Forest seeks to challenge the idea that agricultural land and forested land must work in opposition, but rather, imagines a productive agricultural landscape that is completely forested.

Pattern making was used as a method for realizing the 261 acre master plan, with fluidity working as the central concept. The design utilizes fluidity to create a dynamic landscape with six unique ecological typologies (wetland, forest, orchard, wildlife corridor, tree crop, and pasture), all with different purposes, products, and planting densities. With this, different productive outputs would be expected and desired as each ecological system matures over time. The design is also meant to serve a dynamic role between typologies, with the locations and boundaries of each ecological typology shifting as natural processes and management needs dictate.

A closer look shows the role of Waterman Farm as an educational facility within the Ohio State University campus. As is shown with the Wetland-Pasture Dorm Community, this landscape will serve as a location where students are able to live, work, study, and socialize. By serving the educational, environmental, and nutritional needs of the community, this project aims to show Waterman Farm’s potential as a model urban agricultural park.

BUS STOP PARKLET: Elevating the Public Transportation Experience

Site: Public Bus Stop Location: COTA Bus Stop at Sullivant Ave and Hillitonia Ave in Columbus, Ohio Type: Site Design, Modular Design, Transportation Planning, Construction Planning Tools: AutoCAD, Adobe Illustrator, Adobe InDesign, Site Survey Team: Yichen Yin and Ricky Feria Partnership: Central Ohio Transit Authority (COTA) and Neighborhood Design Center With the goal of reducing the stigma around public transportation in Columbus, Ohio, the Central Ohio Transit Authority (COTA) created a plan to introduce parklets at bus stops as a way to elevate the experience of riding the bus.

Through a partnership between COTA, the Neighborhood Design Center, and Ohio State’s Knowlton School, students were given the opportunity to work in teams to design these bus stop parklets.

I, along with two fellow students, imagined a space that would extend the sidewalk into the street, creating opportunities for additional seating and the introduction of plants at the site. The project provided an opportunity to work through a design from conceptual sketches, through budgeting and more detailed drawings, to construction and completion.

UNWASTED LAND:

An Investigation into Landfills and Wildlife Corridors Site: Generic Site; Along Highway Location: Ohio/Midwest Type: 3D Modeling, Grading, Vegetation Planning, Site Design, Habitat Planning Tools: Adobe Illustrator, Adobe InDesign, Adobe Photoshop, Rhinoceros 3D, Physical Modeling, Trnio While we as humans all contribute to the waste steam, most of us have had little interaction with landfills beyond giving a passing glance while driving down the highway. Additionally, these large mound-like structures contribute little to biodiversity, often covered in a thin layer of soil and short grass. This project challenges current landfill construction practices, looking for ways to better utilize human waste to create landforms with more visual appeal and greater benefit to plants and wildlife.

This design aims to utilize the form of the landfill to connect wildlife habitat. Highways often form divisions in wildlife habitat, placing a strain on wildlife populations and creating dangerous situations for wildlife and human populations as animals attempt to cross roadways. Through the creation of two landfill forms on each side of a highway, which are then connected by a bridge, animals are able to cross over the roadway safely.

By separating organic material out of the waste stream, part of the waste stream can then be composted and used as a soil amendment on top of the landfill. With the ability to alter the landfill soil composition, this will allow for greater diversity in the plant communities chosen to cover the landfill. Placement of these communities will be first aimed at guiding wildlife away from the roadway and over the bridge. Secondly, the placement of plant communities will be guided by the characteristics of and placement of the landform.

QUARRY TRAILS:

Conceptual Renderings for Columbus Metro Parks Site: Quarry Trails Metro Park; Former Quarry Location: Columbus, Ohio Type: Conceptual Plan Rendering Tools: Adobe Illustrator, Adobe InDesign, Adobe Photoshop, AutoCad Team: Bill Buescher, RLA (Design Ideas and AutoCad Plan) While interning with Columbus and Franklin County Metro Parks, I had the opportunity to work with Bill Buescher of the Planning and Design team during the early stages of planning for Quarry Trails Metro Park. This new park design is located on the site of a former quarry, located along the Scioto River in Columbus, Ohio. This 223 acre park aims to provide adventure opportunities for the people of Central Ohio, including kayaking, rock climbing, mountain biking, hiking, and sledding.

The plans depicted here illustrate some of the earliest ideas for this park space. Through conversations within the design department and utilization of my graphics skills, I was able help bring these ideas to life.

ECOLOGICAL CENTER: Creating a Site Plan, Grading Plan, and Construction Details

Site: Open Lot in Urban Neighborhood Location: Columbus, Ohio Type: Site Planning, Grading, Construction Details, Learning Landscape Tools: AutoCad, Graphite Drafting Pencils, Scale, Trace Paper In order to gain experience with site planning, grading, and creating construction details, an open lot in a Columbus neighborhood was chosen as a study location. With an apartment complex currently residing on the site, the new design for this space was to include an ecological learning center, a wetland demonstration space, an outdoor education space, a community gathering space, a parking area, and a bus shelter.

My goal in creating the design was to utilize topography and vegetation to create unique spaces within the site where visitors would be able to have different experiences. A shaded parking lot prioritizes tree cover. The large figural landform offers opportunities for relaxation and a place for viewing performances in the pavilion below. Using a ramp system, visitors are able to visit a rooftop garden and experience city views. Paths leading through grassland and wetland planting areas provide learning opportunities connected to the ecological center.

LANDSCAPE OF TREES:

Increasing Urban Canopy Cover and Restructuring the Education System Site: Columbus Public School Grounds; Open Space in Downtown Columbus Location: Columbus, Ohio Type: Urban Planning, Site Design, Interactive Landscapes, Ecological Connectivity Tools: Adobe Illustrator, Adobe InDesign, Adobe Photoshop, AutoCad, Rhinoceros 3D, Physical Modeling, ArcGIS As the landscape has become more urbanized and the effects of climate change are becoming evident, urban design must aim to link fragmented habitat, provide relief for changing environmental conditions, and connect local residents with nature. The work included here comes from a larger study of the current tree scape in Columbus, Ohio. With a goal to increase canopy cover city wide, the ideas presented aim to imagine how restructuring the education system could lead to an increase in the number of trees in urban areas, with the ultimate goal of creating forested playgrounds, green corridors, tree access in areas with low canopy cover, and communities that are conscious about environmental decision making. The design was realized in multiple parts.

1. Re-imagining Curriculum and the Schoolyard: Current curriculum goals in the state of Ohio and current school yard landscapes were examined. A design plan was created that would lead to forested playgrounds, environmentally focused curriculum, and leadership opportunities for students. This system would help increase urban canopy cover and would connect into a city tree corridor.

2. The Singing Forest and the Educational Corridor: A tree corridor was imagined that would connect educational institutions throughout the city of Columbus. The corridor would provide opportunities for educational exchange, student service, and community learning and relaxation. The Singing Forest is one example of a tree scape that would be found along this green corridor. This design would provide opportunities for visitors to learn about trees and connect with local businesses.

THE SINGING FOREST: AN INTERACTIVE TREE SCAPE

BARK TEXTURE, MUSIC THEORY, AND PLANTING DESIGN

1. Photographic samples for each tree species were used to map the bark texture of that species for each stage of life.

2. Collected bark texture data could then be used to represent a unique set of musical notes. Each note would be linked to the intensity of bark texture in sampled locations.

3. Because bark texture data is considered from multiple points within a tree’s lifespan, the full range of music notes serves as an auditory timeline of each species’ life.

Planting Locations

4. A unique set of 15 notes for each species is then added to a planting plan.

Planting spaces on site are laid out to mimic the lines on a music staff. Visitors to the site can explore the link between tree bark texture and music theory.
