City officials are betting on rain gardens to stop floods from the next hurricane

As the city marks the one-year anniversary of Hurricane Ida, the effects of which have some displaced families still living in hotels, Mayor Adams warns that climate change could lead to intermittent weather abnormalities becoming the norm.

“Thirteen New Yorkers died in their basement apartments due to flooding,” Adams said. “This traumatized our city. But climate change is bringing longer droughts, stronger storms and heavier rainfalls to places all over the globe.”

To help mitigate the effects of the next colossal rainfall event, Adams and other elected officials and department heads were in South Ozone Park last Thursday to announce the creation of an additional 2,300 rain gardens, the continued expansion of the city’s Bluebelt program and other green infrastructure initiatives aimed at relieving some of the burden on the city sewer system that was overwhelmed by last summer’s rainfall.

The city’s sewers were built to withstand rainfall at a rate of 1.75 inches per hour, according to Department of Environmental Protection Commissioner Rohit Aggarwala. Last summer alone, the city experienced two separate instances of rain falling at a faster rate: Hurrican Henri, when per hour totals reached 1.94 inches, and Ida, which dumped 3.75 inches per hour.

“Our path to resilience requires us to look to nature, to augment our sewer system, to build green infrastructure that will compliment our gray concrete infrastructure,” Aggarwala said. “Separately, neither would do the job, but the combination of well-maintained sewers and extensive green infrastructure can make New York City resilient in the face of the storms to come.”

While the city will continue to build out traditional “gray” infrastructure, including the installment of sewers in areas of Southeast Queens that had previously been overlooked, an Ida-level event cannot be contained by sewers alone. Aggarwala says the creation of green infrastructure initiatives eases the burden on the traditional drainage system by redirecting or storing excess rainwater until a storm passes.

Rain gardens — like the one at 135th Avenue and 127th Street where the officials spoke — are designed to absorb water into the ground and help keep the sewer system from being overwhelmed. Bluebelts, a program initiated on Staten Island that has expanded into Queens and the Bronx, involves the adaptation of naturally existing streams and wetlands into stormwater filters, bringing the water away from city streets and into larger bodies of water.

Also announced was a pilot of the city’s Cloudburst program, aimed at redirecting stormwater from city streets into specially targeted public places.

The program’s first run will take place at the New York City Housing Authority’s South Jamaica Houses. Construction is set to begin in 2023, with two grassy areas and a basketball court that will be rebuilt at a lower elevation targeted for water storage.

Similar projects are in planning stages in the St. Albans/Addisleigh Park neighborhood and in East Harlem.

Adams also announced an expansion of the city’s Floodnet sensors, designed to provide real-time flooding data to city agencies, residents, emergency response teams and researchers, along with “daylighting” plans to bring previously covered streams back to the surface in the Bronx.

“This is more than just infrastructure,” Adams said. “This is how we’re going to protect our city and people from rising sea levels and stronger storms. This is how we can create good jobs because it’s about also using one solution to address a multitude of problems.”

“We’re going to continue to be prepared for whatever challenges that we have to face. We will pivot and shift and adjust,” he added.

In a phone conversation with the Chronicle on Tuesday, state Sen. Jessica Ramos (D-Jackson Heights) offered a blunt assessment of the city’s current plan and its response, as well as the federal and state responses, to last summer’s storm.

“A lot of what was released in the current plan is kind of a recount of things that are already being worked on or projects that have been completed,” she said. “Rain gardens are great, bioswales are great, but, I mean, how many are we really going to build and is that going to be enough?”

“It just feels like everyone remembered hurricane season was rolling around again only lately,” she added. “Little has been done since Hurricane Ida last year.”

Major flaws in PlaNYC2030

From the Gotham Gazette:

PlaNYC2030 left out any role for the city's hundreds of neighborhoods, 59 community boards, and the countless civic, community and environmental groups that care about the future of the city. It was a top-down plan, conceived at City Hall with minimal input, and it was never approved as an official plan. In the long term this will only undermine the ability to sustain the plan itself, and both implement and improve it.

The plan now stands at a critical juncture, Rohit Aggarwala, director of the Mayor's Office of Long-term Planning and Sustainability, recently announced his resignation, and the city's budget situation and the overall economic situation have delayed and even derailed some of its initiatives. With Aggarwala's departure and the convening of a commission to review the City Charter, now is the time to fill the gap that excluded neighborhoods. An updated PlaNYC2030 could then be reviewed and voted on by community boards, borough presidents, the City Planning Commission, and City Council, as required in the City Charter.

While the rezonings have opened up opportunities for new development -- also a major goal of PlaNYC2030 -- and protected many other areas, they hardly pass muster as "plans." Rezoning for new development is often done without planning for new schools, transit and other services, nor does it entail measures to deal with existing service deficits or the myriad problems that face communities. In some neighborhoods that have undergone massive rezoning, such as Williamsburg, residents are now up in arms because new high-rise luxury development has overtaxed the capacity of local schools and transit.

While City Planning often echoes PlaNYC's call for "transit-oriented development" by promoting higher density development around subway stops, it does not insure that transit capacity will grow to meet increased needs. Trains and buses are even more overcrowded than they were before the rezoning, and with more service cutbacks planned, the situation promises to get worse. If that's planning it's surely not good planning.

New Yorkers are most familiar with the neighborhoods where they live and work. In this sense they are specialists, and neighborhood leaders and activists are usually a great source of knowledge. Surely they can be parochial and narrow-minded, but so too can people in government agencies. PlaNYC did not look at the city from the perspective of its hundreds of neighborhoods or incorporate the vast experiences and histories of its neighborhoods. Only after the giant spreadsheet was made were the citywide programs and projects broken down, but mostly for reporting purposes.

3rd term not exactly a charm

From the NY Post:

Four months into Mike Bloomberg’s third term — amid a fiscal crisis, the threat from Albany cutting 18,500 city jobs, and of a growing roll call of top aides departing City Hall — Bloomberg appears to be a Mayor alone, his old guard falling faster than the new blood trickles in.

Earlier this week Bloomberg’s longest serving and most loyal and powerful aide, Deputy Mayor of Operations Ed Skyler, announced that he would be leaving by the end of the month to run government relations for Citigroup, where he’ll earn a reported $1 million-a-year salary.

Skyler’s departure came on the heels of Deputy Mayor Kevin Sheekey’s March announcement that he would be assuming a lucrative top post at Bloomberg LP, as well as the departure of communications director James Anderson, who went to work for the Mayor’s charitable foundation.

Bloomberg’s sustainability guru and the architect of PlaNYC, Rohit Aggarwala, also announced this week that he will be following his wife to California after his April 10 wedding, where he’ll start looking for a new job.

After years of loyally beating the drum for their boss, Bloomberg’s top aides are now thinking first about what’s best for them before weighing what fits City Hall’s interests. In total, more than 15 high-level staffers and commissioners have announced their departure since Bloomberg decided to run for a third term.
