Even after Sandy and Ida, NYC still lacks a solid evacuation plan for emergency flash floods

MOCEJ is taking a multilayered strategy to local weather adaptation that addresses a number of hazards corresponding to heavy precipitation, sea stage rise and excessive warmth. On the forefront are inexperienced infrastructure and coastal safety initiatives corresponding to sea partitions.

The citywide plan might be launched pursuant to native regulation, and based mostly on environmental projections from the New York Metropolis Panel on Local weather Change. These predictions might be translated into a number of languages informing communities what to anticipate throughout an excessive climate occasion. It will additionally supply particular options suited to particular person neighborhoods.

The workplace additionally needs to launch the town’s first complete research on environmental justice as required by native regulation 60 and 64 of 2017. It’ll establish deprived communities and decide which of them are lacking out on the advantages of local weather resiliency initiatives and funding.

One such challenge is known as Cloud Burst. It will be piloted in 4 neighborhoods that make the most of the panorama and infrastructure to seize rain from heavy downpours and retailer it safely with inexperienced roofs and increasing inexperienced house.

Different initiatives embody increasing NYCHA’s inexperienced infrastructure and parks, and the town’s plan for a $2.5-billion overhaul of the sewers of southeast Queens and coastal safety initiatives.

“We simply cannot construct these unprecedented large-scale projects,” mentioned Charles-Guzman, who has been on the job for about two months. “This study will lay the groundwork for future potential infrastructure projects.”

Guzman insisted she needs the plan to have a data-driven framework, that means topography, land use, inexperienced house and socioeconomic elements might be assessed to establish options that meet a neighborhood’s wants.

Inexperienced infrastructure corresponding to rain gardens and grass are solely good for absorbing about a couple of inches, in line with Dr. George Guo, a civil engineering professor at Rutgers College. And if it rains 3 inches in a single hour, prefer it did throughout Hurricane Ida, Cloud Burst alone wouldn’t be sufficient. Guo mentioned extra storage is required corresponding to underground or roof high reservoirs, and it should be massive sufficient to deal with an excessive storm. When precipitation is even simply 1 inch per hour, that’s still intense and tough to divert into a pool when it comes down that tough. Then there’s the issue of what to do with the rain water when it’s collected.

“We need to find a way to take the water to the ocean,” Guo mentioned. “There’s a lot of storage right there, and we don’t need to build it.”
