One year after Superstorm Sandy slammed the Big Apple and flooded basements of commercial buildings in Lower Manhattan, several property owners are taking action to make sure their properties aren’t soaked next time.

The New York Stock Exchange, 55 Water St., NYU Hospital, the MTA offices at 2 Broadway and the World Trade Center have each reached out to Presray, a maker of storm water gates, to safeguard their properties.

The Dutchess County-based company is fast becoming the go-to company for storm water solutions.

“We specialize in providing products for flood mitigation,” said Kevin Harris, in charge of the company’s field sales. “We can customize for any application.”

According to Harris, they are working on projects for a vast array of city buildings, ranging from the stock exchange to the New York Aquarium.

At the NYSE on Wall Street, architects and structural engineers are discussing a handful of options that include deploying free-standing barricades in front of the landmarked façade.

“People like their buildings and don’t want big pieces of steel and aluminum on them,” Harris said. A spokesman for the exchange declined to comment on any plans.

For a typical building, when a storm is on its way, barriers can be installed either around the structure or attached to everything but a few exit doors. “When the last person leaves they can put the last piece in,” Harris said.

The MTA is not just hardening its transportation arteries with submarine-like doors and tunnel “plugs,” but is also planning on circling the wagons around its 2 Broadway building using the Presray waterproof panel system.

Public bid results show the lowest price was $2.7 million for the multi-stage project that will include removing and then replacing granite from the façade’s columns after installing stainless steel panel hangers that make the barrier installation a breeze.

In July, the MTA’s Capital Plan was bumped to $34.8 billion due to adding $5.6 billion in mitigation projects on top of the previously approved $4.8 billion worth of Sandy projects.

The MTA has another 30 years to go on its triple net lease for the 1.6 million-square-foot T-shaped office building owned by the Sapir Organization. The agency is responsible for all upkeep and repairs to the downtown building, which at this time last year had some 30 feet of water in its basement.

Led by Alex Sapir and Rotem Rosen, the Sapir Organization has a net operating income of $30 million a year from this building, sources said. Neither was available to comment.

There are many entrances to the building that have to be protected, along with the entrance to the underground garage, which had also been flooded during Sandy.

On Tuesday, the Port Authority said it had spent more than $100 million on repair and mitigation measures throughout the World Trade Center site, and has approved more than $300 million more. Future plans include using security bollards as anchors for a flood barrier system.

Harris said if they are protecting one freestanding building they will make it watertight. But if water can leak into a neighboring basement, they will flood-protect critical underground rooms and install a watertight door.

“Anyone that is proactive knows it will happen again,” said one city source who declined to be identified. “It’s the 100-year storm that is not the 100-year storm.”

A 200-year-old Continental Grain Company will relocate its Midtown headquarters to the GM Building, where it has signed an approximately seven-year, 38,100-square-foot sublease for the entire 15th floor. The lease was extended for the long term directly through the Boston Properties ownership.

Established in 1813 in Belgium, the multinational conglomerate, headquartered in New York since 1964, is one of the world’s oldest food and agribusiness companies.

Continental Grain will move from its current offices at 277 Park Ave. in the last quarter of 2014.

The Newmark Grubb Knight Frank team of Moshe M. Sukenik and Eric Zemachson represented the tenant in the transactions completed with Andrew Levin, who handles leasing in-house at Boston Properties.

Peter Riguardi, Lloyd Desatnick and Michael Shenot of Jones Lang LaSalle, represented General Motors in the assignment to sublease three floors with an asking rent of $89 per square foot.

The 16th floor was previously rented to Reservoir Capital, while the 14th is still available.

Alan S. Cohen and Adam Maxon of ABS Partners are marketing one of the last development sites in TriBeCa that could host a 132,780-square-foot building.

The 10,965-foot development site at 353, 355-357 Broadway, between Leonard and Franklin streets, would be sold along with air rights from No. 359.

Pricing is expected to be about $500 a square foot or $66 million, with the land developed with a high-end residential condo with street retail, especially due to the success of the nearby 56 Leonard project.

The Empire State Building will provide a visual treat for tricksters Thursday night with an LED spooktacular that will incorporate its brand new antenna lighting. choreographed by lighting designer Marc Brickman to songs including the “Ghostbusters” theme and “Monster Mash.” Co-sponsored by Clear Channel, both Z100 and 103.5 KTU will carry the music at 8:30 p.m. If you are too busy walking in the 40th annual Greenwich Village parade, you can tune in later by clicking here.
