TREVIN STEWART 2021 Portfolio
Chadwick Arboretum North This project focused on creating a detailed maintenance regime for OSU’s Chadwick Arboretum North. The goals of my maintenance regime were to reduce emissions caused by mowing, improve biodiversity on the site, and create a unique and aesthetically appealing site through simply varying mowing techniques.

The +
Reduce emissions from mowing Increase amount of plant growth on site Increase biodiversity Offer an interesting aesthetic that challenges conventional mowing practices
Note: Mowing is still done to allow movement throughout the site to continue and to keep the park from looking abandoned, overrun, or uncared for. In still mowing, it makes it clear that the patterns and changes from conventional mowing are intentional. Targeted species: The target of the increased biodiversity is primarily pollinator plants, as they serve to both help the ecosystem while often being ornamental. Some plants in this list may not be pollinators but provide some other benefit to the ecosystem. In trimming, try to allow these plants to flourish by trimming growth around them, but not trimming these. The exception to this is if they begin to crowd out all other species, then trim them back or remove them. This list is meant to provide an idea of plants to look out for based upon their existence in other parts of the site but is not meant to be a comprehensive list. If species outside of this list are found that are also beneficial to the local ecology, they should be treated the same as these species. • • • • • •

The Arrow
The T
Use: A mix of fertilizer and sedum seeds should be filled roughly ¼”- ½” into the Arrow-ator and left to sit. The Arrow-ator itself can be moved once the fertilizer mix is filled into it. This will encourage both a faster growth of the grass under the fertilizer, and hopefully a strong sedum that can withstand some foot traffic. Try to use specific sedum based on the direction, for example use a Red Carpet for the northbound and eastbound rows and Summer Snow for the southbound and westbound rows.

A path is to be considered roughly the width of the mower
•
Reduce mowing to roughly once every week and a half, or until grass reaches roughly 6” in height, whichever comes first
Follow the curve of the berm using two turns, keeping mow paths at roughly the same elevation through the cut. Try to keep the turning points and angle the same for every row.
Mow East to West, and North to South. Skip a row between each mowed row, allow those squares to grow through the year.

•
Mow roughly once a week, increase frequency if grass is growing quickly enough to reach roughly 6” between mows.
•
Mow down entirety of Berm for a fresh start on the first and second mow
•
A row is to be considered roughly the width of the mower
Path’s should be straight, outside the mowing of the circle
•
•
Starting at the third mow, skip one row starting from the West, and add another row every other mow until you reach the top of the berm.
•
Any plants that cannot be managed by a mower or string trimmer (woody plants) should be removed as they are found
Use a string trimmer to trim down patches that are getting overgrown after mowing. No more than 25% of patches should be trimmed in one go, focusing on the most overgrown.
•
•
Pick 1-2 secondary paths to leave unmown every mow. These paths should be mowed with the next mow. Only one of these paths may be the same in next mow

The O
Tool: The Directionator’s These tools are meant to be used to create suggestive one-way paths throughout the park like the one-way paths we find in stores during COVID-19. Once the first mow of this ordinance is done, use the Arrow to make rows one-way paths through the site, determined by the installer, dependent on the manifestation of the mow patterns for the year. Then use the T and the + to dictate intersections as needed throughout the year. The O should be used to designate social distancing for seating. As its diameter is 3’, either spacing one apart or directing visitors to sit one apart will do.
The final part of the project was dedicated to producing a novel tool design that would be used on the site. The tool was meant to be unique, and was more meant to challenge the idea of the typical maintenance tool than to be something entirely practical. While several iterations of the tool were designed, only one prototype was constructed.

Maintenance Ordinance
Goal: To reduce the amount of mowing done on site in order to:
One of the features of this project is that the regime to be written out in an ordinance, something that could be provided to the caretaker to give them instructions on how to care for the space to create the desired effects. Rather than designing a site to be strictly managed in one specific way, the ordinance allows for some variation in maintaining the site, allowing it to grow and adapt over time.

Any plants that cannot be managed by a mower or string trimmer (woody plants) should be removed as they are found
Invasive and harmful species should be removed, ex:
•
•
Starting from the third mow and at the top of the berm, only mow every other row moving east. If there are unwanted species, mow over them and make a connection to the neighboring row
Invasive and harmful species should be removed, ex: • Amur Honeysuckle

•
Allow unmown patches to grow through the season, remove only unwanted species
Stop mowing on a strict schedule, instead aim to mow when the grass gets to be roughly 6” in length Reduce trimming throughout the season, goal should be no more than 10% of patches are trimmed at once
•
If a space is dedicated to mown, begin to keep it mown with the rows. These spaces are intended to provide inhabitable spaces for people, while also offering an interesting way to manage unwanted species. These zones may change and develop throughout the year as diversity changes.
• •
Total mowed area should never be more than 25% of the prairie
Invasive and harmful species should be removed, ex: • Amur Honeysuckle •
Poison Ivy
•
American Pokeweed
•
Garlis Mustard
Fall: •
Remove scheduled mowing, only mow when the grass of the paths reaches roughly 6” in height
•
Begin to choose a secondary path to leave unmown with every mow, and do not mow them again until spring
•
Exception for paths: they may detour around areas with interesting or biodiverse growth as needed, but should return to their straight direction when possible, and as in-line with the previous straight section as possible
•
Keep these paths mowed throughout the season, mowing roughly once a week
Spring: •
Mow three circles of varying sizes, one with one rotation of the mow, one with two rotations, and one with three. Aim for at least one of these circles to receive shade throughout the day
•
Connect the circles with straight mown paths that continue through the circles to the edge of the prairie on either side
•
Pick at least 3 secondary paths that connect the paths going through the circles with each other, the edge of the prairie, or both

THE TOOL
As I was creating more confined spaces during the era of social distancing, it felt appropriate that my tool design address that. Inspired by the one-way aisles of retailers in 2020, the goal of the tool is to fertilize a The Directionators section of grass to cause it to grow in a shape, helping direct people through the space in a safe way.
Step 1: Tool Placement
The Directionator is put into place and filled with an even layer of fertilizer.
The +
The T is used to direct visitors that a 4-way intersection is coming up in areas it may be more difficult to see all paths.
Step 2: Soil Absorption
The Directionator is removed and the fertilizer is left to be absorbed.
The Arrow
The Arrow suggests direction on paths to encourage social distancing in the newly confined areas.
Step 3:Accelerated Growth The areas where the fertilizer was applied should begin to see much faster growth.
The T
The T is used to direct visitors that a 3-way intersection is coming up in areas it may be more difficult to see all paths.
Step 4: Overgrown Directions The directions should be able to stand out throughout the season due to their fast growth.
The O
The O is used to create ground seating that is socially distanced. By having a 3’ diameter, a circle spaced by another circle allows visitors to be comfortably distanced.
Tuttle Park
A BOAT LAUNCH The goal of this project was to create a feature to be added to Tuttle Park. As the site had an area dedicated to a boat launch, I chose to improve on it. Through making an interesting aesthetic, these poles provide seating, boat racks, and a trellis space for plant growth.
As the curves between poles were all unique, creating a trellis structure between them became rather complex. To manage this, I developed a Grasshopper script to create a trellis between two curves, which is show above.

Proposed Axon
AN ADAPTED RIDGELINE As another improvement to the park, I proposed converting the currently empty ridge into a space for the park and neighborhood. By adding layers to the ridge in a stepped fashion it’s possible to create a lot of unique spaces and views to add to the park. The features added to the ridge are primarily focused on providing seating, with some of it dedicated to leisure, some to private seating areas, and some to large spaces to allow room for collaboration. A key driver for this design was its positioning inside a flood zone. Accordingly, it had to be carefully designed to not influence flood levels, as well as to withstand a possible flood.

A HOUSING SOLUTION
The final addition to the park was an area dedicated to providing housing. The goal of these units was to provide a unique living space that is more focused on vertical integration as it scales a roughly 30’ ridge set into the forest of the park. The units would be split into duplexes, with the top box acting as an entry way for both sides.

Example Floor plan The Theory The sizing for the units were inspired by shipping containers, following a recent trend in re-purposing old containers into shops and houses. Through stacking the different layers in different ways, it’s possible to create many unique spaces in the voids it creates. This allows for balconies of varying sizes for different activities that can be unique to each unit.
Preliminary Work Tackling housing was a new concept to me for this project, especially with the unique challenge posed by the steep ridgeline. It took many rough sketches before I decided on the approach I did. Climbing the ridge seemed like a much easier goal than trying to adapt the ridge to the needs of the housing. One key thing I wanted to focus on was allowing these units to each have a secluded feeling, even though they’re duplexes. By following a simple rule for windows on the north and south sides of the units, the sides facing each other, it would provide views of the forest without forcing views of your neighbor.

OSU’s Golf Course An Ecological Redesign
As golf has lost popularity through the years courses have begun to close at an alarming rate. This poses a unique opportunity, as golf courses often have special zoning rules applied to them it would likely be easy to adapt those rules to another unique situation, such as a zone dedicated to promoting local endangered species. As golf courses typically have very strict regiments of care and intensive drainage networks, they’re the perfect site to promote both prairie growth and reforesting with little terraforming or redesign. Because of this, this project was focused on restoring the population of American Bison, Karner Blue Butterflies, and Rusty Patch Bumble Bees. Some endangered plants, the Sugarberry, Scaly Blazing Star, and Little Bluestem, were key to promoting these species’ repopulation.
Riparian Perspec-
Existing Section
One goal of the site was to daylight the large drainage system that was installed into the golf course and use it to create a riparian for the Sugarberries.
Blind Perspective
Terraformed Section Regrowth Section
Final Section Another goal in the site design was to integrate people through the site and allow them to see the ecology without disturbing it. Accordingly, a blind had to be developed specifically for the site. A rendering of the view from the site as well as a section of it help to illustrate how a sunken tunnel would be used to get visitors close to the Bison

The Bison Prairie is an example of the zone the Bison would inhabit, as well as the blind dedicated to circulation. The Riparian Axon is an example of the day-lit drainage area after it’s reforestation. The Pollinator Prairie Axon is an example of prairie space dedicated to strictly pollinators, and providing some space for people to visit and sit while at the park.

FIT FISH
Fit Fish is a redesign of a parking lot along the Cuyahoga River in Cleveland, OH. The goals of this site were to provide a free outdoor space for people to work out while creating a smaller section of the river dedicated to becoming a spawning ground for Rainbow Trout and Walleye to help boost their populations. Different zones were dedicated for different work out activities, each in an attempt to create a unique and memorable place to get healthy. Some of the stream created on site was dedicated to room for water sports and activities, while some of it was restricted to the spawning ground for Walleye and Rainbow Trout.
Modeling Fit Fish
Models to help illustrate the plan for Fit Fish were created using a CNC mill, which allowed for precise details relating to the elevation changed made to the site.
Construction of Models
The construction of these models to a high degree of accuracy was made possible by using publicly available GIS data. The contours from this data were taken and run through a Grasshopper script in Rhino to turn them into a mesh. The buildings were then extruded to their proper heights using Google Earth to measure, and finally this was all complied in the CNC’s software to formulate cut paths.
A Landform of Wood
This project was done with the intention of portraying a landform through the use of wood. It was done in two stages, the first being a model of sticks and the second being an iteration of the stick model using planks instead. I approached this project in a unique way, with far more planning than normal. As I didn’t want to waste wood by making it solid I planned out my model ahead of time by making a plan market with elevation heights and then adapting that into individual sections. These sections allowed me to determine how many different sized pieces I’d need, collect the pieces, assemble them into sections, and then assemble the sections to produce the final model.
The Planar Model
Because of the careful planning I’d used in creating the stick model, it was very easy for me to adapt it to a planar one. I scanned my sectional drawings and loaded them into Autocad to trace. These traces were then used to laser cut precise sections. The flexibility of the laser-cutter allowed me to add in unique features that I couldn’t have done otherwise, like the cavern and archway.
A Collection In Space
An Internet of Things This project was done with two goals, to explore the vast amount of free 3D models available and to develop my skills with rendering using Vray for Rhino. A Collection in Space is just that, a collection of free 3D models envisioned upon a shelf drifting through space. Aboard the Ship is a model of my desk envisioned upon a ship and populated with models from the Collection. Where it began is a diorama also created using models from the Collection, though it uses solely models provided by NASA. While not dedicated to any practical design, I found this project to be very fun, unique, and intriguing. It gave me a chance to refine some of my skills with these programs while exploring a creative idea, which I greatly enjoyed. I admit, it feels like a cheat to use color solely for this page, but it’s a piece of work that truly lost a lot of detail in black and white, so I chose to leave it as it originally was.

A Daily Routine
These projects are primarily art related, but were essential to developing skills in Photoshop. Mapping Ephemerality is a collage done with the goals of showing the temporal nature of the site. From the passing of animals to the passing of planes, it tries to capture what it feels like to be at the site in a still image. A Daily Routine was focused on showing multiple steps and movement through the overlaying of many pictures and their blending. It’s simply a visualization to the steps of making tea. Rendering a Model was done with the goal of adding context to a theoretical landform designed and modeled in Rhino.

5th and Forsythe, Columbus This project involved creating rough construction documents for a proposed redesign of the unused elementary school found at 5th and Forsythe.
The school would be repurposed into apartments. The sports field would be dedicated to a learning center neighboring a plaza lined with a retention swale. The parking lot would be dedicated to an outdoor pavilion and open yard. There would be space dedicated to “flex” parking for events. This parking would be a large open field with many parking spaces constructed using mesh-like supports to prevent cars from suffocating the grass there.
Plan
Construction Pictured are drawings explaining the construction of some of the features on site.
Preliminary Work
This project was given with precise requirements for the size of different zones throughout the site. Due to this, it took several iterations done to help decided how to fit it all within the dedicated space. As much of the grading on site was changed, it was also important to figure out how the contours that illustrated that would appear and what these changes would do to the site.
W. Broad + S. Belle, Columbus This project was done in a City and Regional Planning class I took to further my understanding of zoning regulations. The focus of the project was to provide a development plan for a large parking lot neighboring Columbus’ Veterans Museum and Memorial. The goal was to transform a largely unutilized parking lot into a shopping center that would provide many amenities to the neighborhood while finding out what rules this development would have to follow. This ranges from anything from usage of the space, setbacks from the road, building design, to even the materials used to construct the building. This project was done through picking zones and the design of the space followed by drafting a thorough Planned Unit Development that would be submitted to the city for review before the project would be pushed further.

This project was done in a class as a collaboration with COTA and the Neighborhood Design Center. The goal was to design and create a small modular parks that could be placed at bus stops in the hopes of creating more public spaces. This is another project that simply lost too much in transferring to black and white, so it got a pass too.

Bus Stop Parklets - Columbus Along with designing a layout and purpose for the parklet, we were tasked with figuring out its construction as well. While the option was available to acquire prebuilt furniture, my group decided to figure out our own construction so we could create a more unique parklet. We stuck to simple shapes to allow it to be modular in case the design needs to be adapted to a different shape in the future.
*The constructed parklet you see here is not the one designed by my group. We were only able to get permitted to do one parklet over winter a test, the rest will be constructed in the spring.
