This award winning project explored strategies for infrastructural opportunism. Analyzing the systems of coal-fired power plants led to many potential interventions. The use of excess or wastes in its systems provided an opportunity for interventions. Through thickened hedgerows, power plant waste water reuse, carbon sequestration, and biomass as renewable energy production gives Picway Power Plant a new meaning. By simply understanding existing systems and augmenting them by repositioning their own wastes, Picway Power Plant achieves not only a new aesthetic, but also new operative - habitat patches and corridors are enhanced, thickened impoundment caps provide cover for both animals and a plane for biomass cultivars to be produced, waste water provides a 365-day water fowl environment and subsequently birding on a new scale introduces the human to this machine, and potential CO2 capturing provides

a future energy resource as Ohio looks to diversify its energy portfolio.

Over 72,000 gallons of water are pumped from the Scioto and used to condense water from gas to liquid daily. The water is then outlet, usually at temperatures 15 degrees warmer than at initial intake, before entering the Scioto River again. Thermal shock occurs near outlets jeopardizing plant and animal life. Understanding this cycle led to one of the first interventions - keep water on-site to ensure proper heat dissipation and in turn create freakologies and augment plant and animal life. Standing water during winter months (higher water temperature) allows for waterfowl habitat instead of migrating to other regions.

The Strategic Management and Planting Timeline shows four operations or variables throughout the life of the power plant. Historically, the site has experienced deterioration of riparian corridors, adjacent hedgerows, soils, and water ecolgoies. Interventions in different phases allow for new growth, program, and ecologies to be introduced or emerge. Disturbance regimes allow for control of invasives, establishment of pioneer and planted ecologies so as to help ensure their success. Programmatic interventions are increased with the opening up of wetlands and other lands which the power plant will not use.

Picway Power Plant Land Management Strategy

6Section through Wetland and Capped Areas

A massive cut/fill strategy is reorganized. Creation of wetland areas are produced by the need for capping impoundments - dried slurry. Larger or broader cuts create thickened caps, capable of facilitating a diversity of plant life and therefore fostering more wildlife and bio-mass potential. These mounds now create vantage points and activities unfamiliar to the Columbus area.

Section through Warm Water Ponds

Condenser water is pumped in to the ponds for thermal dissipation. This water - generally 15-20 degrees higher than at intake - funnels through a series of ponds. Warmer water tempratures help produce biota foreign to the region - freakologies. The water remains open throughout the winter providing waterfowl habitat in a 365-day environment.

The Presidio is one of San Francisco’s most precious hidden treasures. Its landscape is divorced from the fabric of the city in several ways; differing geometries, suburban fabric, expansive views, varying and uncomfortable scales,

infrastructure, and vegetation.

At the Main Post of the Presidio we encounter the Presidio Bluff, an area which will open up lands/connections to Crissy Field, with the tunneling of Doyle Drive. In this proposal historic geometries are upheld and language from Crissy Marsh is pulled through the site - carrying both tidal water and stormwater run-off. Through vegetation and other interventions the site provides a new dynamic and scale to the expansive Crissy Field area. The bluff itself borrows its language specifically from topographic anomolies along much of Baker Beach to the west as well as the serpentinite and colma outcroppings found along the Bay. The expanded main parade lawn holds strong throughout the site as it makes its way across Mason Street. It will be home to new progammatic space as well as a place for the new visitors center to reside - recessed slightly into the bluff to conceal and uphold panoramic views to the bay.

The term sustainability is pervasive. How do we integrate stormwater management ideas, which are thought of as singular objects, into the urban fabric while activating the public realm? The Short North Cultural District in Columbus, Ohio provides us with many areas, both conventional and unconventional, when we think of the public realm. Can we add green infrastructure to the mix of High Street, a well travelled corridor to improve the quality of life along it? The following studio had a unique development in that 1) groups were formed to analyze area data, resulting in bold infographics, 2) space typologies in the Short North - niches, setbacks, and open lots - were explored through a SWM lens (see typologies and detail), and 3) to intervene in a specific typology and develop it (see Service Station Re-use).

How Green is C-bus?

Groups were formed to analyze multiple data. In this case, transportation data allowed our group to understand current modes of transport as well as relative conditions in the Short North. As an avid cyclist bicycle data was vary compelling. Infographics help convey the stark contrast in auto vs. bicycle facilities - locally and regionally. These graphics were my own creation and interpretation of data.

The Short North District has varying setbacks along High Street - from 8-20 feet. Addressing these variations presents challenges. Permeability, as a lens, was put to test on each typology at varying ratios (25% to 100%). Explorations initially in sketch lead to several considerations for varying setback

conditions.

The intent for this infill project was to capture not only the history of the parcel, but also its performative potential, while providing a much needed open space in the Short North District. Also, to provide overlapping programmatic spaces, or layers, through which visitors can engage with the site in various degrees. And finally, to work programmatic zones in with ecological

processes - harmoniously.

The outdoor “Lawn” allows for multiple activities atop and below. Beneath the plinth, visitors (and transit patrons) can store items in lockers, lock their bikes, or grab a quick snack. Furthermore, the rear face of the Lawn couples as a climbing wall. Wetlands provide remediation of water as it works its way through the site collecting from various point and non-point

sources. Through these areas, visitors may not be able to engage directly at ground level due to toxins present in soils, but can engage partially through elevated boardwalks.

Ohio State’s Chadwick Arboretum is home to an array of wood plant material. It is being pressured by long-term visions for west campus as OSU begins to create critical mass east of the Olentangy. Chadwick is to be re-envisioned as a place for learning, an array of experiences, habitat enhancement along the Olentangy, and an extension of ideas put forth in the One Framework Plan by Sasaki Associates. Exercises were completed

to understand context - at varying scales - and its implications at the site.

Through this course we are challenging some initial ideas and proposals put forth in the previous quarter. Within design development our proposals were further developed through ideas of character, management, and space as ways to portray and further understand design intent. Various scales and edge conditions

were explored.

TRANSECT DETAIL DEVELOPMENT

Iterative exercises led to the challenging of initial proposals within our Schematic Plan. I explored another transect in the next phase of design development - two programmatic areas near the Nature Center. Here, details and smaller organizational elements were explored; water runnels, tree vegetation, material selection, and a redesign of the Center’s architecture were explored. A construction documentation phase will follow in Spring term.

Exploration of this Modernist residence began with modeling, drafting, and understanding Neutra’s design intent with the Kaufman House. This home would then be placed on a site in Columbus, OH. We were to analyze its own systems and conditions through site analysis and inventory. With this information I iterated through the siting of the building

which was to then be developed into a set of preliminary construction documents.

In this proposal, inspiration was drawn from the slight variation in topography near the south edge of the site. A depression of about 12 feet allowed me to site so when approaching the home one would only see a small second floor. As you approach the home your view is deflected away from the home where only slight glimpses of the house itself are seen until it appears before you as you enter the small auto court. As with its original intent, the home was sited to maximize southern exposure for solar thermal uptake. Further details include a robust outdoor lawn, viewing

terraces toward the river, contrasting vegetation, and a Corten retaining wall mimicking Neutra’s design concept.
