Traveling is one of my favorite hobbies. Photography not only captures beautiful sceneries, but preserves my travel memories and feelings.When taking pictures, I consider colors, scales, and a 2-point perspective to deliver a sense of places.

Photography can also express social aspects. These three photos have the same theme called “seating”. The photos were taken on the same day and same place. Interestingly, people indirectly showed their mood/feelings through their behaviors based on how and where they sit.

The homeless lady was sitting on the corner

of the bench that was located in dark area.

She seems not confident at all. This shows the feeling of loneliness.

On the other hand, one couple was lying down on a similar bench. They seem really happy and were relaxed in the bright sunlight on a Sunday afternoon.

This lady chose to sit down on the edge of the wooden walking

deck, not a regular bench. She seems really tired from walking in the hot weather, so she sits

down anywhere she feels comfortable.

The wetland functions as a water filtration system as well as an important habitat for our focal species. The polluted water being pumped from the arboretum flows through the wetland and is cleaned before it enters Putah Creek. Mule deer, otters, giant garter snakes and many other birds and a wetland dwelling animals will be able to utilize the newly created habitat. This wetland will enhance the quality of Putah Creek an the surrounding landscape.

Schematic section shows how the

wetland manages flood situations and fluctuating mudflat

levels, which provides habitat for

animals.Note:

and Hannah Levy rendered the plan.

The playhouse project was for 2-5 years old kids at the Center for Children and Family Studies at UC Davis. Based on the analysis of the site and kids’ behaviors, the children need a playhouse that educates nature, provides adventure, and promote active play. Different elevations can give them physical strength by making them move up and down. Green roofs and walls can give them learning experience of nature and plants.

The current condition of the UC Davis courtyardsnear Shields Library and the Olsen Hall contain plenty of impervious surface and lack of vegetationin the site. Concrete materials show signs of aging and erosion due to the improper design of handling stormwater runoff.

The heavily used bike parking lot in front of Olsen Hall is on a surface of decomposed granite, which cannot absorb stormwater runoff. The current design of the walkway creates inconvenient connections to other places. However, this area has the potential to be improved by creating a stormwater management system such as rain gardens and improving circulation of bikes and pedestrians by wider walkways.

Site Analysis

Shields Side PathA Shields Rain GardenB

CThe former amphitheater transformed into a unique outdoor gathering space to inform visitors the importance and function of treating stormwater runoff. The curvilinear walls represent the flow of water. Water runnel planters allow water to fill each terrace that not only helps the absorption of runoff but also gives an aesthetic appeal. From an engineer’s perspective, the stair runnels are also feasible to build since the design keeps the existing concrete stairs.

The site in front of the Olsen Hall is redesigned to not only treat stormwater runoff, but also to improve pedestrian circulation. Increasing the width of the entrance path creates a sense of gate way to Olsen.The courtyard near Shields Library is utilized by creating a food court so that truck vendors can come inside. People can sit at the tables and have small snacks between classes.Note: The project was done by a group. Ray Papa rendered perspectives and Gary Ng rendered sections.
