Some Flooding Scenario Maps for Greenpoint and Long Island City

  In the maps below, I show some flooding scenarios based on  New York City RIM files.  These maps are produced on a "what if" basis if the polar ice caps should melt at a steady pace going to the year 2080.  These flood maps seem to be based on elevation.  In the recent local news, in the real estate sections are reporting  increased building activity in the Greenpoint and Long Island City areas of Queens.  Many of these zones of increased building activity are taking place a few hundred feet or less near the waterfront.  I am sure that the developers of these projects are taking into effect future water levels.  I would like to tell my readers that they should not make any decisions based on these maps.  I cannot tell if these maps are accurate or if the water level will rise due to melting ice caps.  I thought that the readers should be aware of this, if they are not so already.  Last weekend, the "G" train that was closed down for underwater tube reconstruction reopened.  It goes through the target area.  These Greenpoint tubes suffered much water damage due to superstorm Sandy.  I also wanted to show  mapping techniques as well.  It is possible to get a typographic map of New York City from the Rutgers' University Map Lab and bring it into a ARCGIS map. What is nice is that this file does not need to be geo referenced.

In the above map, I bring in the street pattern for Greenpoint Brooklyn and Long Island City Queens.  The black thick lines are the subway routes in the area.  You will see three flood scenarios for the area for years 2020, 2050 and 2080.  The location of the "G" line is indicated.  The "G" train crosses the Newtown Canal as indicated by the arrow.

In the map above, I brought in one flood stage scenario (2020), subway routes and a typographic map from around 1975 of the area.  This can be obtained from the Rutgers" University Map Lab.  It can be added to an ARCGIS map very easily.  At the Rutgers University Map Site, select New York City Typographic Maps.  Choose the "tile" that you need and download it as zip file to your desktop.  Open your already existing map in ARCGIS and add the *.tiff file after the file that was downloaded was unzipped.  It does not need to be geo referenced which can be a pain.

 

 



The map above is produced by GRASS and shows the direction and strength of water flow for the area based on rain and elevation.  The direction and thickness of the bars shows flow and direction.

I am not an expert in reading this but it seems that surface waterflow is not an issue for the area.  Notice the big waterflow vector for the Lower East Side of Manhattan to the left of the map.

New Proposals for Light Rail in Long Island City Queens and Red Hook

Hi Folks: I just looked at Bob Diamond's website and there is new information regarding proposed light rail for Long Island City Queens, New York City along 21st Street to Queens Plaza and to Red Hook later in the future. Just heard about this a half hour ago.

The picture below comes from one of the publications listed in Bob's posting on the subject.  I believe it is a rendition of a proposed light rail line in Queens.
Looks kind of cool?    But,  I do not see any wires.

Deputy Mayor Doctoroff & Other Prominent Urban Planners / Developers Enthusiastically Endorse BHRA's Brooklyn Streetcar Project Former First Deputy Mayor and Current Chairman of Bloomberg LP Daniel Doctoroff, the Chair of Brookfield Associates (and former NYC Planning Commission Chairman) John Zuccotti, and Former NYC Planning Commissioner Alexander Garvin (currently Garvin & Associates), have now whole heartedly embraced and validated our streetcar project. Adopting BHRA streetcar project's route selection, our construction cost estimate of $20 million per route mile, as well as the types of project financing, which we incorporated into the "New Streetcar Possibilities for Brooklyn" (BHRA' PowerPoint presentation on our Red Hook streetcar project), which we gave several months ago at several venues, and which has been publicly available ever since then. The full version of the "Next NYC" forum sponsored by the Regional Plan Association, introducing the streetcar line now being championed by Doctoroff, Zuccotti and Garvin is available here as a PDF or here is the web address. Doctoroff, Zuccotti, and Garvin, are extensively cited in the article above, and Doctoroff even stated that out of the 40 projects featured in their urban planning booklet, The Next New York, that OUR PROJECT (the streetcar project) IS THE BEST ONE - and I quote: "New York has never been a light-rail kind of town—“toy trains,” said a Koch deputy mayor dismissively in the 80s. Yet the time has surely come." "This is the book’s single best idea, said Doctoroff. It would knit together the emerging communities along the 7 and L lines, and would trigger all sorts of incremental growth on the Brooklyn-Queens waterfront, where the greatest potential for growth actually is. What’s more, light rail is cheap—some $20 million [per mile], he guesses." Compare this to the $/per mile figures we cited in Our Presentation. "Zuccotti agreed about light rail, and emphasized that new transportation projects should be in Queens, Brooklyn, and the Bronx, because that’s where housing can be built at reasonable cost in areas that are still zoned industrial. He cited the brilliant precedent of David Walentas, who showed definitively in Dumbo, Brooklyn, how to convert empty industrial space into a thriving mixed-used community. Can the same be done in the Bronx and Queens?" According to Garvin: "The capital cost of the new light rail line could be financed from the tax increment generated by new and renovated housing created on underutilized properties within walking distance of the new light rail line." Doctoroff, Zuccotti and Garvin even seem keen on some of the alternative funding mechanisms we presented. Please read the wording of both documents very carefully, especially the part about financing construction/operation via future real estate tax generated along the route (see slides 12 & 32 of Our Presentation) BTW, their entire booklet, The Next New York, can be downloaded here as a PDF. The streetcar project is on pages 12- 13. Note, the map on PDF page 13 of The Next New York, and compare with the maps page of our website. The light rail plan described in The Next New York even utilizes the exact route we've long advocated - passing through the Borough Hall mass transit nexus, then proceeds through the historic Atlantic Avenue Tunnel, and then down along Columbia Street into Red Hook, ending at a streetcar barn at Gowanus Bay Terminal :-) There's an old saying: no man is an island unto himself. In the spirit of this Election Day season, BHRA stands ready and eager to form new partnerships and coalitions with like- minded groups and individuals who share our common goal: to bring about the return of the streetcar as a key transportation mode in the City Of New York.
