The benefits of Sponge City design

In many of cities, the under land of city is too hard and the consequence of this situation is the underground water become less and less. This makes a huge amount of waste of water resource. In my view, the solution of this problem is decreasing the hard landscape and increasing the soft landscape as well. Therefore, I will illustrate some methods of how to design a city to increase the underground water.

Firstly, we need increase the soft landscape to make the water permeating into the ground. The pavement plays an important role in it. There are many pavements can reaching this goal, such as “cross pattern paving” (Figure 1) and “water Permeation brick” (Figure 2). These pavements could help to keep the raining water and create a better micro- environment of city.(Figure 1: cross pattern paving)

Secondly, the roof garden could keep the rainwater as well. The most popular method we could see in roof garden is that using the water storage to keep the rainwater. After that, the water in the water storage could be filtered and for the usage of that building. On the other hand, roof garden is also good for making a green city. In many Asian cities, there are too many high rises just because of the high population. The roof garden is one good choice for Asian cities to make the city greener.

In conclusion, the water, which we gain from sponge city, can be used it for many things. Like flushing toilet or washing car and irrigation. In the future, I think this concept of urban design will become more popular. In many countries, “sponge city” has been written in the police. I hope this concept could benefit to all the cities in the world and make our earth better than before.

  1. Zack’s blog mentioned about an interesting topic – “Sponge City” that making me curious a lot. This concept is about making fully use of the underground water. In this blog, Zack discussed about two ways for “Sponge City”. First solution is combining soft landscape with hard landscape instead of fully hard landscape. The soft landscape is helpful to permeating the rain into the ground so that improving the water circulation of the rain and underground water. Secondly, he talked about the roof garden. The water storage on the roof is for collecting the rain waiter. It can not only sever the plantings, but also for the whole building. Because of the high population, there is a huge demand of resource for daily life. We can not only rely on the existing resource and consume it without worries. It is necessary for us to discover more methods to save and make sure we can make the most use of the resources. Sponge City is a great example for us to realize the sustainable scheme for our daily life.
