At a street corner in South Jamaica Community, Queens, New York City, the original plain asphalt pavement has been transformed into a sunken green space. When rainstorm comes, it will absorb tens of thousands of gallons of rainwater like a sponge. This seemingly simple renovation is one of the most iconic attempts by New York City to address climate change——The epitome of rainstorm Pilot Projects.

thisresilienceUrban reform originates from aAn unexpected disaster——The rainstorm brought by Hurricane Ida in 2021New YorkThe fragility of the traditional drainage system has been exposed, and the entire city60% of the areaDue to the use of sewage and rainwaterCombined sewer systemofDrainage system,Once the rainstorm drops sharply, the drainage system is unable to discharge excess rainwater in time due to insufficient design capacity, namely, lack of buffer capacity. Sewage and rainwater overflow together, forming urban waterlogging and combined overflow pollution, indirectly leading to bacterial breeding, and also causing digestive tract and respiratory tract infections of the affected residents.

Queens South Jamaica CommunityThe narrow strip close to Jamaica Bay is reduced to"reservoirThe 72 hour torrential rain of Hurricane Ida in 2021,Encountered the most severe flood disaster,Community waterlogginghighestDepth reaching1.8 meters.Among the residents living here,30% of the annual income is below the poverty line of the United States. The rainstorm has completely overturned their low, damp, but narrow residence with the last bit of body temperature. According to statistics, more than 20000 residents were affected, accounting for 70% of the total number of permanent residents,This century old city urgently needs new solutions，It can not only solve the raging rainstorm and flood, but also help the vulnerable groupscreateComfortable, safegreenofSpace.

New York CitygovernmentRealizing that it is necessary toDisaster preventionFacilities and CommunitiesCare for vulnerable groupsdeep integration，This dual appeal has led to the rainstorm pilot plan，andPriority should be given to South Jamaica community in Queens, where rainstorm occurs frequently and poverty rate is high. Through the combination of natural system and gray infrastructure, the city should be reconstructedresiliencehydrologic cycle.

In terms of design and planning, New YorkCombining rainstorm management with community renewalconstructSunken green space，Adopting a layered structure, planting flood resistant plants on the surface, filling the middle layer with crushed stones to accelerate drainage, laying anti-seepage membranes on the bottom layer to prevent groundwater pollution, transforming the school playground into a permeable ground, and even laying permeable asphalt in the fire escape. These facilities are usually used as public spaces, and the water storage function will be automatically started in rainstorm. existIn the summer rainstorm of 2024, the time of waterlogging and ponding will be shortened from an average of 4 hours to 45 minutes.

New York will alsoThe abandoned street corner green space in the South Jamaica community has been transformed into a sunken rain garden,andPlanting organic vegetables，pass throughThe 'From Rainwater to Dining Table' plan directly supplies 300 low-income households in the surrounding area. Residents participate in planting, picking and receiving vegetables for free, and the rainwater collection system provides irrigation water for crops.

Even more innovative isThe "blue-green roof" system combines traditional roof greening with rainwater collection devices,Built in water level sensor,Weaving a monitoring network through the Internet of Things,abilityreal timeSend eachNodalwater levelStatus, data directly connected to the urban emergency command center，Provide data support for rainstorm disaster relief plan.

In the next five years, New York plans to expand the pilot experience of South Jamaican communities throughout the cityIn 20 high-risk areas, the standardization of the rainstorm Manual in New York was promoted simultaneously. This urban revolution centered on "resilience care" is not only reflected in technological breakthroughs，The deeper significance lies in endowing vulnerable groups with dignity through spatial transformation, bridging social rifts with technological innovation, and making climate resilience a solemn commitment of cities to every individual's life. As the climate advisor of the Mayor's Office said:We not only need to prevent cities from being submerged, but also make every raindrop an opportunity for community rebirth. The essence of this resilience revolution is to pour the steel and iron bones of the city with humanistic warmth
