DEP Declogs Sewers, Helps Jamaica Bay by Ivan Pereira - YourNabe.com

Read original...

The city Department of Environmental Protection started its spring cleaning a little early and said it will not only result in less flooding in Springfield Gardens but also improve the Jamaica Bay ecosystem.

The agency announced Monday that it completed its work on the 12.2 miles of sewers under Linden and Springfield boulevards, where there have been several reports of flooding due to clogged storm drains.

For its initiative, DEP crews used Vactor trucks that suck the debris and garbage out of the sewers and transport the rubbish to a waste treatment plant in Manhattan before being shipped to a landfill. DEP Commissioner Cas Holloway said southeast Queens was chosen as the first location for the removal not only because of the complaints from homeowners who had to deal with the flooded streets, but also because of the area’s proximity to Jamaica Bay, where wastewater is discharged.

“We started this effort in Jamaica because we know that localized flooding is a problem for some residents and to protect Jamaica Bay — one of the ecological gems of New York City,” he said in a statement.

The trucks removed more than 1,500 tons of debris from the sewers that were clogging 20 percent of its pipe volume, according to the city agency. Some of the trash included tires, construction materials, large rocks and a 15-foot ladder, the agency said.

In 2001, the DEP installed an 8-foot-by-17-foot storm sewer in Springfield Gardens to deal with heavy floods in the area, but on several occasions, most recently in August, the neighborhood still experienced flooding during severe rain storms due to clogged drains.

Special sonar technology and closed-circuit cameras were used to pinpoint the exact locations of the debris in southeast Queens, the agency said.

The two $450,000 trucks contain a 30-foot hose that is inserted into the sewer through a manhole cover and sucks in the debris after the pipes are flushed by a separate water jet, according to the DEP.

The agency estimates that the cleanup reduced combined sewer overflow, which contains both wastewater and storm water, that goes into Jamaica Bay by 25 percent and will help improve the water quality in the ecosystem.

The bay has lost huge portions of its saltwater marshland due to a high concentration of nitrogen in the water. Four DEP wastewater facilities have been discharging the nitrogen into the bay and the agency has been working to fix the problem through several multimillion-dollar initiatives.


The DEP commissioner said the truck would be cleaning sewers in other parts of the city in the near future.

“Optimizing our existing sewer network is a key part of the NYC Green Infrastructure Plan, which will save New Yorkers more than $2 billion when fully implemented, and will dramatically reduce CSOs,” Holloway said.

'Green' Median Project between North and South Conduit Aves. to Take Strain Off Sewers by Lisa L. Colangelo - NY Daily News

Construction worker labors North and South Conduit Aves. project, which would reduce rainfall flowing into city sewers.
The grassy median between North and South Conduit Aves. in Ozone Park has become a test area for one of the city's largest green infrastructure projects.
The 13,000-square-foot site will be transformed into a natural water filter in an effort to keep stormwater and rainwater from overwhelming the sewer system, according to officials from the city Department of Environmental Protection.
"It's an innovative, ecological, green way to treat stormwater," said John McLaughlin, director of the DEP's Office of Ecological Services. Instead of treating stormwater as waste "it should be viewed as a resource."
As part of the $730,000 project, the grass will be enhanced with trees, wildflowers and shrubs. But the major work will take place below the surface where a bio-retention zone will be created with vegetation, sand and soil.
It is designed to divert about 200,000 gallons of stormwater from existing sewer lines. That's about 90% of the water from a moderate storm.
The project is part of a larger citywide push to find more environmentally-friendly and cheaper ways to cleans stormwater, officials said.
Mayor Bloomberg announced in September the $2.4 billion NYC Green Infrastructure Plan. The goal is to cut the amount of sewer overflows by 40%.
In many parts of the city, stormwater and wastewater are carried through one sewer system. When that system is overwhelmed - often by a influx of stormwater - a mix of the two is discharged into New York Harbor.
The city has been looking for ways to divert some of that stormwater through so-called green roofs and other places where water can be naturally absorbed and cleaned.
The alternative is additional sewer infrastructure, which could cost billions, officials said.
The challenge is finding and creating patches of green, large and small, around the city.
Green spaces have disappeared in Queens and other parts of the city, partly because of overdevelopment. Lawns have been paved over and open tracts of green land have been replaced with commercial and residential buildings.
"One system alone may not make a dent in the combined sewer overflow problem," said DEP Deputy Commissioner Angela Licata. "The idea is to have several of these strategies in an area."

Into The Tunnels: Exploring The Underside Of NYC by Jacki Lyden - NPR

Read original...


Listen to audio at site and see slideshow


Steve Duncan lives dangerously. The urban explorer goes underground, examining the hidden infrastructure of major cities all over the world — their tunnels, subways, sewers.
In New York City, his favorite underground adventure, he could drown when the tide comes in or succumb to toxic gases in the sewers. He could be hit by a train or step on the third rail. And if he gets caught, he would be so under arrest.
So why does he do it? If you could have followed Alice down that rabbit hole, or Jules Verne to the center of the Earth, or gone to see the mandrake god in Pan’s Labyrinth, wouldn't you do it? It's seductive. It's mysterious. It's what lies beneath.
Duncan, 32, is a graduate of Columbia University working on his doctorate in urban history at the University of California. He looks like a human sparkler, with a shock of white-blond hair.
Call him what you will — including crazy. But while you sleep, he's plunged far below the city surface — headlamp on, an urban mole, exploring the nether regions of New York.
Producer Brent Baughman and I followed Duncan — not down every manhole, but, hey, we stood anxiously beside a few — on a journey through 25 miles of New York City underground.

Steve Duncan, an urban explorer who has examined the hidden infrastructure of major cities all over the world, emerges from a manhole in New York City.
Exploring What Lies Beneath
Duncan, master of the "Undercity" (you can find his photographs at Undercity.org), had arranged a trek with Nordic explorer Erling Kagge. Kagge, who is in his late 40s, has completed the trifecta: He has summitted Everest, hiked the South Pole, and he was the first man to walk alone to the North Pole. He's killed a charging polar bear with a shot from a handgun.
Looking a bit like Thor, Kagge showed up in a cherry-red sweater with a big white furry heart.
"I'm always asking myself why I can't remain sitting in my chair," he said, changing into some webbed long underwear at midnight on a freezing Bronx street corner. "I'm not always waiting for the answer. I think most people underrate the possibilities to fulfill their own dreams. So I think much more is possible in life than people seem to believe. We're all born explorers."
He called the underground hike a trip "through New York's subconscious."
We waited in the snow as the explorers descended below, along with a videographer and a New York Times reporter. The men climbed over a wall and lowered themselves into a freezing stream flowing into a culvert. They vanished. They would have to walk 30 or 40 blocks, with their waders on, to a climb out of the previously scouted manhole on the residential street in the Bronx where we would be waiting. A colleague of Duncan’s patrolled with us.
One hour passed. Then two. Then three.
"Mole men, this is topside, come in!" spotter Will Hunt called into his radio over and over. Just after 5 a.m., they emerged, filthy and elated. They had been in beautiful, double-barreled brick sewers built in the 1890s. But there had been some water problems; Duncan jettisoned leaking waders.
Then, it was off to cross the Harlem River to the subway, head back south and find a place to sleep. We had sleeping bags and backpacks. We needed warmth. Columbia University, Duncan's alma mater, was the target.

'The Big Thing Here Is Not To Get Killed'
Employees filling vending machines in Buell Hall didn't give us a second glance as we headed downstairs to the basement. Steam tunnels below the university were made famous in the 1968 student sit-in. Duncan jimmied a locked door with a knife, and we wormed through darkness and beside pipes into a coffin-sized passageway next to heating ducts and the boiler. Oh, to be warm and dry — if dusty.
Each explorer seemed to sleep like a stone. Breakfast was bourbon and cough drops at 4 p.m. — for strength. Then, we climbed back up and emerged into the philosophy department — during the faculty Christmas party. Backpacks and hiking boots didn't quite fit the dress code, so we retreated back into the night, reluctantly.
The second night out was beginning, and after a brief stop at the New York Athletic Association on swanky 59th Street — an underground river runs beneath the building — we ended up somewhere off Delancey Street, contemplating visiting abandoned subway stations. By now, it was after 1 a.m.
Unfortunately, the subways I saw were nowhere near as abandoned as I'd expected. There were no express trains, but we had to avoid service trains and other, unscheduled locals. Duncan gave this inspiring speech:
"The big thing here is not to get killed. So don't touch the third rail. If a train's coming, get out of the way. That might mean — in the worst situation I can imagine — that might mean standing in between two third rails and two pillars with trains coming on either side of you. You will get seen, but you won't get killed."
We walked stealthily, single file like a special-ops team, until he halted.
"I could have sworn I saw a guy over there," he whispered. And then we were running. Was a train coming? Were we being chased? I was at the end; who knew? I heard a loud police whistle. A worker? A security guard? A cop? We ran. At a subway platform, to the astonishment of passengers, the men hauled me up, backpack and all. Why were we doing this? Well, this part may have been a miscalculation, Duncan said.
The Canal Street Sewer in Manhattan, New York's first covered sewer, was roofed over circa  1812 -- previously, it was an open ditch (the "Canal" of Canal Street).

The Canal Street Sewer in Manhattan, New York's first covered sewer, was roofed over circa 1812 — previously, it was an open ditch (the "Canal" of Canal Street).
"It was a little nerve-wracking tonight," he admitted. "But I think there's a lot of really fantastic parts of the city’s infrastructure that are not morally bad to experience. I'm not doing immoral things down here, and I think these things help people see the city for what it is: a fascinating place that's grown over time. But you try to explain that to a cop arresting you and you're not going to get very far."
In 2001, a SWAT team swarmed him on the roof of the Cathedral of St. John the Divine and nabbed him.
That's the dilemma of this kind of urban exploration — of seeing things most people will never see.
The 'Mole People,' And Another Close Call
Kagge, who is writing a book about happiness, wanted to interview the "Mole People" who live off the Amtrak tunnel below Riverside Drive. One of them, Brooklyn, lives in an "igloo," as she put it — a sort of dump beneath the tracks, which were lined with mural after mural of intense, weird graffiti.
"What do you think people above ground do wrong in life?" Kagge asked her.
"It's called appreciate what you got," Brooklyn said. "And hold on to it. And don't lose it. I don't know why people are miserable — they got everything that I don't have. And I'm happier than them."
Soon, she burst into Sister Sledge's "We Are Family."
After that, the explorers went on to crawl below Canal Street in lower Manhattan, in an old sewer they entered through a manhole. It was so narrow, they were soon lying flat. Rats and cockroaches ran past their heads. Raw sewage splashed them. They showed up at my flat at 7 a.m., frozen and happy and very, very filthy. But apart from a little scrubbing up, there was no stopping.
The last leg of the journey was through Queens. They had now been in nearly every borough of New York, and Duncan and Kagge wanted to hike through a storm sewer that emptied into Jamaica Bay. The manhole was in a forest in Queens. They popped the lid, climbed down rusted ladder runs — and walked into the Atlantic.
"It was pretty scary ... the tide came in about an hour earlier than I expected and I got wet to my waist. But it was awesome," Duncan said.
Kagge, the polar explorer, termed it "a proper expedition" — from the North Bronx all the way out to the Atlantic.
"It's been superb," he said.
And I'd agree.

Residents Seek Answers on Ozone Park Sewer Plan by Bryan Yurcan - Queens Chronicle

Hundreds of residents came out to the Ozone Park Civic Association meeting Tuesday looking for answers about potential eminent domain proceedings in the Centreville area.
About 500 Centreville residents received letters last week from the city Department of Design and Construction regarding the long-proposed HWQ411B sewer project. The letters stated that the city might need to use eminent domain to acquire some property in order to complete the work.

Civic Association President Howie Kamph said he was flooded with calls from concerned homeowners, and decided to invite DDC officials to the meeting to speak to them directly.
Rather than conduct the meeting in a traditional manner, DDC representatives set up seven different stations, and — according to their address — residents went to the proper table to find out what, if any, property the city might need to take.


“This was the best way to do it, this way the DDC can have a one-on-one conversation with every homeowner,” Kamph said. “It’s better than an open meeting with everyone screaming.”


Originally proposed 30 years ago, the HWQ411B plan calls for the replacement of several water mains and sanitary sewers in the area, along with the additions of new storm drains, which would help alleviate the community’s long-time flooding problem.


According to Narayana Venugopalan, an assistant commissioner with the DDC, about 150 properties in the neighborhood will be affected.


He said homeowners will lose no more than five to 10 feet of property, mostly curbs and sidewalks in front of their residences.


“It won’t be more than a sliver,” he said.


A public hearing on the $40 million project is scheduled for Nov. 30. Venugopalan said work on HWQ411B will begin either in late 2011 or the spring of 2012.


“We are finishing this project,” he said of the long-delayed plan.


Ozone Park resident Anna Quarto was one of many who received the eminent domain letter and came to the meeting with concerns.


Quarto said she found the session to be informative and was glad to discover that no one will be losing their house.


“I think people in general got scared when they read that their property might have to be acquired,” she said.


Her husband, Lenny, said he is glad the project appears to finally be moving forward.
“It will definitely make Ozone Park better,” he said.

City Finishes $20 Million Sewer Upgrade for Maspeth - Queens Ledger

Read original...


Two years and $20 million later, a flood-prone section of Maspeth has a new sewer system.

The city has finished replacing combined sewers, water mains and catch basins along 54th and Maurice avenues, Department of Environmental Protection (DEP) Commissioner Cas Holloway announced June 21.

The infrastructure project, started in August of 2008, targeted the section of 54th Avenue between Maurice Avenue and 58th Street, and Maurice Avenue between 54th and 56th avenues.

It was started in August of 2008, one year after severe flooding hit Maspeth and Middle Village. Since then, civic groups and elected officials have lobbied for a better sewer system.

The upgrade includes 35 new catch basins, 2,692 feet of new combined sewers, and the replacement of 3,392 feet of distribution water mains.

Holloway said it would “substantially reduce flooding in Maspeth, and ensure that the water supply network continues to deliver healthy, great tasting drinking water for years to come.”

The project is part of a larger effort to overhaul aging sewer and water distribution networks in Queens. The DEP has budgeted another $1.7 billion through fiscal year 2014 to carry out the work.

“Investments in our infrastructure make our communities safer, reducing sewage backups and providing our residents with a quality water distribution system they deserve,” said Councilman Jimmy Van Bramer. “The completion of this project marks a great day for Maspeth residents.”
