The spaces in between buildings and their roofs are good spots to hold rain water. This means that it can prevent excess water from flowing onto the streets and flooding them but instead stay on the roof of the buildings. Shoppings centres can collect the rain water on the roof and use it for flushing toilets or to water rooftop gardens. However, green buildings are expensive to build, hence experts suggest incorporating green strategies in future building plans.

2)Build a more pipes or drains
As it would be too expensive to build everything to prevent a flood, we cannot deny simple and less costly solutions like building another pipe or drain, at the cost of some land space. These extra pipes and drains can channel out a lot more excess rain water away to prevent floods in areas.
3) Have pavements made out of porous concrete or detention basins.
Porous concrete can store some rain water in their pores, while detention basins can stem the flow of water in the event of sudden heavy downpours, helping to reduce the possibility or severity of a flood.

4) Stop complaining, start acting
Instead of complaining about floods, we ourselves should do our part to prevent them. We should stop littering as litter can clog up drains and hence cause floods. The PUB will install more debris traps in drains too to prevent debris and litter from being washed into drains and clogging them.

Despite the worst weather-related natural disasters the world can offer--floods and tornados, as well as hurricanes, droughts, and forest fires--the ancestors of all our native wildlife evolved to deal with them. None of these phenomena ultimately affect healthy populations of wildlife. And of course no wildlife affect the weather.
