2016 72HOURS URBAN ACTION Awarded 1st Prize Site: 906-16, Bangbae-dong, Seoul, South Korea Instructor: Youngmin Kim Coworkers: Somi Go, Sujung Kim 72 Hour Urban Action is an upcoming voice in the global movement of participatory tactical urbanism. The teams design, build, sleep and party on site to generate interventions in public space within 3 days, a tight budget and limited space.

RESTORE 225

SEOUL ZOO - SQUIRREL EXHIBITION DESIGN

Site: 13702 leighwood avenue, Baton Rouge, Louisiana

Site: Seoul Zoo Squirrel Exibition, Seoul, South Korea

In the wake of the recent floods in Louisiana community, there are a number of great opportunities for those of people not affected to volunteer and give back. My primary goal as a landscape architect – fueled by experience volunteering ‘Restore 225’ on last semester to help flood victims in our community – is to achieve environmental and social equity through projects.

What we did was helping them to take apart all the floors and built-in furniture.

Behavioral enrichment is the environmental enhancement of the lives of animals in a managed setting by providing them with mental and physical stimulation to increase natural and healthy behavior. In other words; adding a little creativity, fun and stimulation to our animals’ lives.

Design is founded on their natural habitat to reproduce endangered prevost’s squirrels.

Geographic Information System Practice, Fall 2012 Instructor: Eunhyung Kim Site: Suwon-si, Gyeonggi-do, South Korea The incoming population grows as Gwanggyo New Town is built. This, there has been a gradual decline in the quality of water because of recreational facilities and domestic waste water. To restore the quality of water, it is necessary to establish a sewage disposal plant.

Geographic Information System plays a significant role in searching the suitable land for sewage disposal plant. I found good areas and bad areas by geoprocessing, then extracted and buffered data layers. When I erase bad areas from good areas, finally I could find suitable areas.

Solution 1. Bus Bay Problem : Bus Stop is too close from the intersection and the entrance of transfer center.

60m

Solution : Move 60 meters to the west and then install ‘bus bay’ which relieves traffic tie up and enhance passengers safety. decleration busstopacceleration lane lane lane

bus station length 60m total length (160m)

Solution 2. Reversible Lanes Based on traffic volume, change one Sanseong exit lanes into entry lane during rush hour to shorten queues

Solution 3. Lengthen Entry

TRANSPORTATIOIN ENGINEERING Studio: Transportation Engineering, Fall 2013 Instructor: IlJun Jang Site: Bokjeong Intersection, Jangji-dong, Songpa-gu, Seoul, South Korea This project is to ease the traffic congestion in Bok-Jeong Intersection by planning highway facilities and controlling traffic volume elastically. This plan would help reduce travel time expectation and move people and goods safely and efficiently on streets and highways.

Move 100 meters from Bokjeong Intersection to Sanseong direction. Lengthen entry lane increase in lane capacity and change traffic cycle elastically.

Award: 6th Urban Forest Design Competition, Director of Korea Forest Service Prize (3rd) Site: Sinheung-dong, Gunsan-si, Jeollabuk-do, Korea People would experience the modern history of the Gunsan. Start with the ‘Japanese Colonial Forest’, visitors would go through independence plaza and experience historical stage. People can enjoy the top of the forest, appreciating the beautiful panoramic scenery of the city. Without saying a word, people can be engaged in Gunsan history.

Zone A: Forest of Japanese Colonial

Zone B: Forest of Development

Zone C: Forest of Gunsan Future

People might feel the oppressed history of Japanese imperialism when they pass through the forest composed of Metasequoia in high density.

As go through Independence, people would be dynamic and active. They overlook the panoramic view of the city and Keum River Estuary at the top of the forest.

Citizens could rewrite noble history with every generation. Without saying a word, every generation can be part of Gunsan future.

CATFISH PLAYGROUND Studio: LA7021 Site Design Site: St. Louis Street, Baton Rouge Louisiana Instructor: Cat Marshall The site is a sloped, empty lot that is surrounded on three sides by busy primary and secondary street. In the past, the site was called ‘Catfish Town’. Solution to the problem is founded on a strong design concept: Catfish to cope with major drainage problems and create a playful space.

impervious paving that related stormwater management issues. This concept intends to play a significant role in improving stormwater management cleansing the storm water runoff by reducing bacteria in the watershed.With several design components such as a cistern for irrigation, this concept shows that we can overcome this challenge in artful and interpretive way.The concept is designed to enhance the water quality in Capitol Lake, with the goal of reducing runoff and filtering rainwater runoff before it leaves the mansion’s impervious surfaces.

This project is for the multiple purposes of reduction in bacteria loading, public education, and recreation of a stormwater demonstration for visitors and students.
