As an urban planner, my goal is to provide environments to ensure the safety, health, and welfare of communities and neighborhoods at human dimension through design and strategic planning. In cities, public space functions as transition and connection between properties. I believe planners should focus on the design quality of public urban space to make the best use of them providing complete infrastructure and public services to all neighbors.

A RENOVATION PLAN FOR DOWNTOWN CHAMPAIGN, IL Urban Analysis + Design, 2017

This Project contains two sections: an urban analysis of downtown Champaign and a proposal to improve existing issues and problems. The purpose of the analysis is to talk about when, how and why the downtown Champaign becomes the way it is. The proposal is to talk about what can it be in the future by analyzing its connections, land use, neighborhood development, infrastructure and to provide a design proposal. Lynch’s analyzing method will provide the basis for renovation plan, together with other study report, a more health-developed heart of Champaign could be created. The study area lies in Champaign-Urbana, a twin city in eastern Illinois. The oldest street in this neighborhood is over 60 years old while the youngest about 30 years. Here lives about 1505 people according to the U.S. census Bureau, The zip code they commonly use is 61820. When defining the study area, the team intentionally included all important buildings and landmarks that are closely related to the traditional civic functioning of downtown Champaign, as well as the residential and commercial units that are two blocks within the core area in order to dig into the interaction of different land usages and the effect of natural and artificial traffic obstructions (Healey Street detention basin and the rail) Course: UP 426 - Urban Design Principles Instructor: Devin Lavigne, Kai Tarum Collaborator: Nibing Peng, Claudlene Saint Vil

REGIONAL CONTEXT

Downtown Champaign sits at the intersection of south-north and east-west railroads. It also locates at the center of Champaign-Urbana Metropolitan. The strong connection to different directions, leading to some larger major urban centers such as Chicago in the north, St. Louis in the south, Springfield in the south-west, and Indianapolis in the east, make downtown Champaign potential for high concentration of commercial and service industry. With the campus town i.e. University of Illinois-Green street corridor, and downtown Urbana, several major employer centers are defined in the region: University of Illinois campus (for education); Carle and Presence Covenant Medical Center (for health services); Downtown Urbana and Savoy (for services and recreation); Market place (for retails and recreation); U of I research park (for research and innovation). For a long time, downtown Champaign had played a role mostly in civic service. It stays connected with it surrounding area mainly through bus and roads. East-west bound roads are more important regarding the layout of Champaign-Urbana is also east-west.

LAND USE ANALYSIS

Urban mixed use and multi-family residential occupy a high proportion of area of downtown. Commercial and urban mixed use develop along Neil Street and University Avenue, with parking lots surrounding the center. Public open spaces locate at the edges of downtown area and are attached to residential. Community facilities also massively locate in downtown area. Currently, the several industrial businesses still remain in downtown area along the rail road, reflecting the old rail-oriented pattern of industry. Referring to general context, Downtown Champaign is sparsely developed. Building sizes and location diverse a lot, commercial, mixed use, institutional and civic building are in relatively bigger sizes, tend to locate in central downtown and have bigger gaps in between due to vacant lot, parking lots or green space. Some gaps such as Boneyard Creek serves important environmental roles and should be well preserved, while some vacant lots have only negative effect to either traffic condition or neighborhood density. Surface parking also massively sits in downtown area which reduce the building density significantly.

VEHICLE, BIKE, TRUCK, SIGNAL LIGHT & ONE-WAY STREET

Most signal lights gather in main area; Too many one-ways (1 out of 2 arterials, 2 out of 3 collectors, plus 2 out of 5 paths) adds difficulty to route choosing; Number of collectors equals that of major arterial, thus collectors are not enough; Road width of is too narrow prevent traffic congestion during peak time. Take the only two arterials as example, Neil St. has 2 lanes for two directions and one spare lane, and Kirby Ave. has 2 lanes for two directions, no spare lane. There are two different shapes of street lights, one of them does not provide enough downward light for road. Currently these parking spot serve for banks, restaurants, car dealers, maintenance and interior decorating; Rich potential truck parking area could support further commercial development; There could be more truck parking spots in southeastern area if the density is to be improved. Compared to the area defined by the boundary, the 5 bike trails are far from enough; Sustainability of the neighborhood could be improved if there is an integrated net of bike lane, however currently these lanes are not fully connected; More bike lanes should be added to path, especially in eastern and northern part of the area.

LYNCH ANALYSIS OF EXISTING NEIGHBORHOOD ELEMENTS

This section analyzes the main elements of downtown area with Lynch Element Analysis. Nodes: three nodes clusters in central part, the buses around Illinois terminal could aggravate the traffic burden of Neil. St. Edges: Railroad and Healey Street detention basin in southeast are two edges that could not be bridged, west side park could only be accessed by pedestrians, other than that, transferring vacant land to buildings can strengthen the interconnection of different land parcels. Districts: in recent 20 years the major change of the neighborhood is the renovation of Neil St. Which tightens the connection of the neighborhood by improved traffic condition. Paths: the sidewalk width and railroad problem has been mentioned in last page. Landmarks: Although there is considerable portion of commercial land use, nearly all nodes marked belongs to civic service, partly due to the civic service role that the downtown has long been playing. Most nodes lie in west of the railway, which shows the railway barrier has hindered the spreading of civic service spot.

Existing Surface Parking

STRATEGY - SURFACE PARKING

The building density in downtown area remains relatively low due to the surface parking occupying space between buildings which shapes the fragmented pattern. The parking is design for more than actual demand regarding the number of parking. Up to thirty percent of parking is wasted. Moreover, the paved hard surface increase surface run-off during storm weather, and therefore, it creates significant stress on the drainage system and increases possibility of flood hazard. The renovation plan provides strategies to improve the exiting conditions. Currently, downtown Champaign has fifty-eight surface parking. Forty-two of them can provide less than forty percent of the total parking, 1500 space, which indicates that most of the surface parking can be integrated to a larger parking, Parking building is a feasible option for downtown. Two parking buildings are in use currently, providing seven hundred parking space. To utilize space most efficiently, the plan proposes to build a parking building with capacity of five hundred parking space at Walnut and Washington to replace surface parking at the north-east corner of downtown area. It also proposes to build a parking building at University and Neil with capacity of five hundred parking spaces to replace surface parking in the south-west of downtown area. The proposed south-east parking building at Illini Terminal providing four hundred parking space can serve as the parking center for Illini Terminal and the surrounding area. After the reconstruction, the city of Champaign can either change the land use of the original surface parking for new development or for open space and green infrastructure. This movement can beautify the downtown area and can create a walkable community for all.

Pedestrian

STRATEGY - COMPLETE STREET

Walking is encouraged in downtown area to reduce stress on the traffic system. Streetfront area for stores are enlarged to create more space for walking.

Current traffic condition in downtown Champaign is not satisfied. Speed limits on Neil Street is 35 mph. However, drivers report that when passing through downtown area, speed can hardly reach 25 mph. Moreover, the downtown area is not friendly for neither pedestrian nor bikers. Due to the one-way setting of Neil Street, bike lanes

Instead of filling the gaps with buildings, another ideal plan is to introduce a green infrastructure system and low impact development.

The part of the water will be transferred to detention basins, while the remaining can fulfill the water consumption of the green roof in dry weather. The installation of green roof system requires a strong structural intensity of the roof and building itself. About forty percent of commercial and urban mixed-use buildings are qualified for this renovation. A twenty-year plan is made for this movement, with public buildings being the first, then the commercial and mixed-use buildings, lastly, a part of residential.

800 SQ. FT. DWELLING Architectural Design, 2018

The building locates on a ten-degree slope inclination, with a northwest-southeast creek running through. To adapt the dry climate, also to make the best use of exterior space, the stairway is installed inside the wall, instead of in the building. And therefore, the vertical circulation is implanted to the wall. The building is built with concrete and giving a sense of heaviness. The thick outer wall can be as thick as two feet to bear the stair and structure upon it. The inner wall, is set to be four inches to increase heat exchange. Several openings are set on the building to promote light and circulation of fresh air. In total of four floors, the first floor and the third floor are defined as double height to create a comfortable space for the living room and the study, while the kitchen / dining room, and the bedroom keep to height of nine feet to generate private experience.

THE 301 HOUSE Architecture Design, 2018

The 301 House is a dwelling for a young couple in Kyoto, Japan. Commissioned in a 4 x 10 m site, this building rises to three floors allowing a total area of 120 sq. m to fits living room, kitchen, bedroom, recreation room, and an art studio. Due to the restriction of the site, the project starts with stacking cuboid. With pushing, offsets are set at each floor. Pushed walls are filled with concrete. The un-pushed sides are installed frosted glass. The whole building stresses a combination of heaviness and lightness. Major components are frosted glass and concrete. Walls and floors are built with solid, plain concrete without any cover on the surface. Frosted glass surrounds the exterior of the entity of building without touching the walls. The glass is hung on the large concrete support which is also supporting the floors. The frosted glass material is set to allow lighter coming in to the building which is closed in three elevations and surrounded by houses from three directions. The facade is open to street. To provide better privacy, arrayed concrete sticks rise in behind glass, preventing direct penetration of light and unexpected view from outside. A concrete gate in front of the building is a abstract version of the Torii (鳥居) reflecting the couple’s Japanese identification. The gate does not provide real security. Instead, it helps create an extra cover for the living room and stair up to the bedroom.

VILLA FARNESE GIACOMO BAROZZI, 1559 Architectural Analysis, 2018

Villa Farnese (Palazzo Farnese) was built by the grandson of Pope Paul III and designed by Giacomo Barozzi in 1559. The regular-pentagonal building stands at the key point of the town of Caprarola. At each of the vertex of the pentagon, there is a observatory. A tower standing at the top vertex is the highest point of the complex even in the town. The regular-pentagonal floor plan makes all the vertexes of the five observatories touch the boundary of a perfect circle which includes the whole building. Squares and circles are most commonly used to manage space. Pentagonal arrangement of space creates a structure with thick walls at every direction and therefore these walls provide complete protection to the delicate courtyard and the interior of the fortress. The designer utilized space maximumly through creating rectangular floor plans for rooms and setting spiral staircases at the corners. Spiral staircases can make the best use of space and more importantly, well connection to all directions, where lookout windows are usually set. Structures facing inward to the courtyard are fabricated with less solid materials such as wood and veneer masonry.
