Site Plan of the Bergen Arches

Main Focus-The Arches About 50’ below its urban context, this sunken landscape is ignored by even people living next to it. To create more connections to surrounding communities and give people easy access to the Arches, I soften the southern edge of with cut and fill and created several ridges and valleys. The ridges will connect to the previous underutilized parking lots and form entries for communities. The valleys will function as bio-swales and treat runoff from those communities.

Grey & Green Infrastructure System In this proposal, grey and green infrastructures work together to manage storm water. Underground, the old railway tunnels will be connected to the re-oriented storm drain system and become cisterns for runoff. Inside the cisterns, the gross firstflush will get a centralized treatment before getting into the irrigation system. Above ground, the landscape are terraced and planted with different species so as to absorb different pollutants from the water.

Concept Formation Step 1: Locate underutilized parking lots

Step 2: Cut and fill to creat ridges and valleys

Step 3: Terrace the ground and plant according to soil humidity

Step 4: Lay out pathways and entries

Termite Control Strategies According to the studies on termite habit, the main foraging zone of termites is 10m-40m from the mound, where the soil suffers from nutrient depletion. However, the soil in the inner circle (within 10 meters from the mound) is free of foraging and stays nutrition-rich. The difference in soil condition results in completely different vegetation types. Therefore, my strategy is to create termite-repellent landscape in the outer circle, meanwhile set up symbiotic relationship between termite and plants in the inner circle.

How to live along with termites?

Mound with closed ventilation system

Compost

Offer adequate alternative food sources

Inner Zone with shallow passages underlain by deep radial passages

Main Foraging Zone with network of radial and cross passages

Peripheral Zone with small passages after ending blindly

Plant Litters

Manure

How to deal with the mounds?

Remove the mounds + Spread mound soil to enrich surrounding area

Use termite-repellent plants

Intercrop repellent and susceptible species Keep the mounds + Set up symbiotic relationships

Raize the termite resistance of the landscape Rotate between repellent and sesceptible species
