Coexistence of Water and Green Space—The Park Plays an

Important Role in the City

In designing the flood retention amount, although the Central Park’s area cannot hold all the
flood retention amount in the re-planning district, it plays a critical role anyway. Two grass
slope flood retention ponds were designed since the Central Park has to accommodate 7519
m3. Generally, for the rainfall less than the amount of 5-year recurrence period, rain can flow
into the box culverts through the road ditches without decreasing the water amount. Besides,
the runoff with more serious pollution can flow into the flood retention grass slope, so that
it will not cause sediment that affects space utilization. In fact, only the rainfall more than
the 5-year recurrence period’s amount flows into the grass slope through the box culverts,
and slowly infiltrates as time goes by, so that the flooding speed and the water pressure in
the downstream can be lessened. By conducting a test, the result proves that the grass slope
remains green even it is soaked with rain, which carries out the design concept of coexistence
of ecological flood retention and green space.

Memory in the Space, New Life in the Old Camp Dormitories

There are originally 22 dormitories in the Ping-shih Camp, and 17 of them were torn down
and recovered as the permeable green space. Two dormitories’ walls in the northern camp
district were broken down to be reconstructed as the pavilions, toilet room, and leaf compost
field, while three in the southern district was transformed as “the Environmental Art Center”
by the architecture design team. The inner space’s compartment was also torn down to conduct
structure strengthening and internal decoration. In addition, the ceiling structure was exposed
as decoration so as to serve as the space for exhibitions and activities. It is expected to be rented
by the citizens or exerted as the space for the civil groups, foundation, or cultural and creative
units. Actually, what links the three buildings is the gallery which shape is like wind dancing
in the woods. As a result, the gallery is designed as the curve that ingeniously shuttles through
the woods in order to coexist with the trees. By such design, the gallery not only connects three
dormitories, but also defines the skeleton of the exhibition & performance space, showing that
it is a vital image of the south-to-north and east-to-west entrances.
