GREEN & BLUE INFRASTRUCTURE
islands are created by simple cut and fill to transform the concretepaved ground into a spongy and porous landscape , which is expected to retain stormwater from the surrounding area during the monsoon season ( up to 200,000M3 ). This tilled landscape also turns the otherwise hard clay surface soil into a wet and spongy habitat allowing a rich native community to be established , with minimum irrigation or maintenance needed during the dry season . This modular landscape can be easily executed by one singular digger and minimizes its dependence on labor skill and makes the army operation feasible .
The foundation and foot of each islet are consolidated using recycled concrete materials . While preexisting trees are to remain at the center of individual islands , young seedlings of the canopy trees are planted on each of the newly constructed mounds at minimum cost . The wetlands are designed at two elevations , with a deeper core area and the terraced shallow shoreline . The latter is connected to the linear water remediating wetland built along the north and west border of the park that filtrates the contaminated water from the canal , and cleanses 8152m3 of water from the poorest V grade to III grade each day . The amount of cleansed water is enough to keep the wetlands nourished during the dry season and turn the shallow shoreline into a life supporting ecotone that allows a lush vegetation community to be established .
Secondly , while the major roads are preserved and reused , a leaner cut is made in the middle of the pavement
