A place suffered from flooding twice yearly &, while it was waiting for millions of dollars to improve the draining system, it should have developed automatically triggered motorboats & floating warehouses to be used once a flood alarm was activated. Once the river water level reaches a critical level, the town shall have a floating warehouse (an inflatable warehouse with air and material strong enough to cope with floods) ready and allow low-lying residences to store their valuable assets in this floating warehouse. When there is a flood, motorboat rescue teams shall take all residents of low-lying land to a victims center on higher ground. Their valuable assets such as home appliances and furniture can all pre-stored at the floating warehouse to reduce losses. A special zone on higher ground shall be set aside for car owners to park their car.
