Midtown Atlanta, GA 2016.1 ULI Competition Susan Piedmont The project is developed by a 5-person multidisciplinary student team 2 Architecture, 1 Landscape Architecture, 1 Urban Planning, 1 real estate management
Atlanta’s Midtown holds a promising and vibrant future. Though lacking a dynamic residential neighborhood, the development site sits at a nexus of cultural, educational, and economic institutions critical to the identity of Atlanta. The core concept of The Midtown Gateway is to stitch together the area’s underutilized assets and cultural landmarks through the creation of a dynamic, retail-centric mixed-use neighborhood. The substantial ad acencies of Georgia Tech, The V arsity Restaurant, The 19 9 6 Olympic Torch Tower, and the B ank of America Center lack safe, pedestrian oriented connections. The Midtown Gateway strengthens these ad acencies in multiple dimensions.

The pro ect site is located at one of the most walkable and crowded area in Atlanta. B y providing a node point like a gateway, we believe that this pro ect would be very successful in both revitalization and profit.

According to existing topography, proposed rain garden is located at the very low point of the site to collect and filter as much runoff as possible.

The success of this pro ect lies in connecting Georgia Tech, Peachtree Street and Public Transit, block D by developing pedestrian tunnel, new bike trail system and walkable sidewalk.
Block E, which is where MARTA station with a bus hub is located, is the only high- density development allowed area. We transf ered the bus stop to the on- street parking area on West Peachtree Street and manage to come up with an o ce tower that not only matches the exsiting context but also goes up to 0 oors high.

With the development of waste industry, more and more landfills are abandoned around the world. However, the pollutants and potential hazards remain. How to resolve the pollution and renovate old landfill sites become a big challenge for landscape architects. By presenting our study through drawings and diagrams, we are trying to build a basic understanding of waste and landfills.

BALTIMORE As cities in the U.S thrived during industrial revolution in mid-nineteenth Century, people soon found the severe pollutions and bad living space became the most important issues. The result was the birth of the modern public parks. PARK Baltimore’s park system began around mid nineteenth Century. The oldest public park in Baltimore, Patterson Park, which is the biggest green area in the map, still serves the public as a 137-acre recreational space in the middle of the city.
SYSTEM ANALYSIS
site analysis
The study of exisitng piers and decks around the Baltimore Inner Harbor helped me think about the similarities and connections between oyster farming and deck structures. Taking advantages of the existing structures help me to fit my proposal into the Inner Harbor area or even the whole Baltimore Park system.
multifunctional oyster spit
In the Chesapeake Bay, the eastern oyster population is experiencing a resurgence after decades of dramatically low numbers. Baltimore Bivalves challenges designers to transform a 16-acre portion of Baltimore’s urban waterfront into an Urban Oyster Garden: an environment that celebrates oyster cultivation and consumption and creatively fosters public engagement with food production. The design aims to create an aquatic and terrestrial public landscape with on-site oyster cultivation, bivalve water filtration zones to cleanse urban water, and seasonal oyster markets. I explore the spatial qualities and performance of oyster beds, artificial reefs, and oyster shell stockpiles and will expand the traditional design palette of the landscape architect.
