TIME LINE OF URA PLANNING

Waste of Resource

Water:

Let the stormwater stay longer in the low area and slow down the speed of water in Tagore Stream while irrigating the vegetation in the condo.

Trees: Plan the layout of building to follow the location of trees and utilize other trees to be the material of playful facilities and pavement.

Land: Apply the core tube as the structure of the building to fit the topography and minimum the earthwork and utilize the excavation to shape the landscape terrain.

How To Manage Water

The Role of Streams in Tagore Forest

Water sources of two streams

Tagore Stream has 4 managed sources however Lentor Stream has only 2 managed source, which means Tagore Stream is much more important than the Lentor Stream on the aspect of water connector due to its complicated structure.

How To Manage Water

Catchment of the Two Streams

According to the formula of the peak discharge calculation Q = c i A The peak discharge of Tagore is almost 2.6-times than that of Lentor. Because the catchment area of Tagore is 2.5-times than that of Lentor and the degree of slope in the catchment of Tagore is also much steeper than that of Lentor which effects the coefficient.

QTagore = 2.6 QLentor

Capacity of Flood Storage of the Two Streams

Tagore Stream has stronger capacity of floud storage than Lentor Stream.The lowest area is just the place where 4 source finally join and the cancel of Lentor also will give a little burden to Tagore. It can be used as bioretention swales. The concret canal of up reach of Tagore should be naturalized and also planed a small pond in the junction of the three branches.
