DEC: Hudson River Communities Must Prepare for Sea Level Rise

I haven't read the whole report, but I jumped to drinking water treatment because that's the first and most important impact I would expect Esopus will deal with. Here's what the report said:

Salt water intrusion...threatens the Hudson River, which is a primary water supply source for many communities.... Saltwater intrusion could affect freshwater intakes at the Chelsea Pumping Station, Castle Point Medical Center, Poughkeepsie, Port Ewen, Highland/Town of Lloyd, Dutchess County Water Authority, and Rhinebeck.

In addition, flooding and other sea level rise impacts pose many of the same risks to drinking water treatment facilities as those that threaten other infrastructure types: corrosion, erosion and deterioration.

Water treatment plants in the coastal zone are at risk from flooding and the associated corrosion caused by salt water infiltraion. In addition to the treatment facilities themselves, the substrate for distribution pipes could be damaged by erosion and a rising groundwater table....

Costs of necessary repairs, placements and updates to New York State's water infrastructure over the next 20 years have been estimated at $38.7 billion, although estimates of the costs of modifications to respond to climate change specifically have not been developed. These costs will, however, be significant.

In my mind, the Port Ewen water treatment plant has already likely been damaged by climate change, in combination with poor runoff management. Why? Climate change is expected to produce more frequent strong storms, and it's very strong storms on the order of 100-year storms that have repeatedly caused erosion that damaged the water treatment plant.

Upstream, Dealing With Flooding on the Wallkill

The TH Record today has a report about steps taken (or, mostly, not taken) to address flooding on the Wallkill River, as well as the Esopus and Minisink. The Wallkill forms the western boundary of the Town of Esopus. The article focuses on efforts in the Black Dirt area of Orange County, once the nation's premiere onion-growing region and still a major agricultural center. The Black Dirt region is essentially a prehistoric swamp that's been mostly drained to create amazingly rich and productive soils ... that are also highly erodable.

One interesting point in the article:

"Since 2005, the Black Dirt has suffered three floods that models predict should happen only once every 50 years."

Note that climate scientists have predicted that global warming will result in more intense short bursts of precipitation. The NYS Department of Environmental Conservation predicts that "Rising sea levels and strong storms will cause localized floods and threaten shoreline infrastructure and development," as one local consequence of global warming (from Fact Sheet: Climate Change in the Hudson Valley, also available as a printable pdf.

In other words, this upstream problem is likely to continue to affect the Town of Esopus in the coming years, so we should keep an eye on developments with this flood-control project.

1/22/09: Sea-Level Rise Meeting

Public Invited to Meetings on Rise of Sea Levels
State Task Force Seeks Input on Adaptation Planning

Thursday, January 22
4 to 7 PM: Open House
7 PM: Presentations
Nelly Goletti Theatre
Student Center, Marist College
Poughkeepsie, New York

The public is invited to a series of meetings about the effects of sea-level rise and the development of recommendations for dealing with rising sea levels, New York State Department of Environmental Conservation (DEC) Commissioner Pete Grannis announced today.

The meetings, sponsored by the New York State Sea-Level Rise Task Force, will be held at four different locations -- in Poughkeepsie and Manhattan and Suffolk and Nassau Counties.

Each meeting will feature an informal open house session followed by staff presentations and a public-comment period. The open house includes exhibits related to various aspects of climate change andsea level rise. Agency staff will be available to explain the exhibits and answer questions. Those interested may come at any time during the scheduled open house. The meetings give the public an opportunity to provide input on the task force's work plan.

"Global warming is one of the most significant environmental and economic issues of our generation. I commend Commissioner Grannis and his staff for convening this important planning group and urge thepublic and elected officials to participate in this process that will help the state chart a responsible course on this issue," said Governor David A. Paterson.

In his State of the State speech last week, Governor Paterson addressed global warming by calling for one of the most ambitious clean energy plans in the nation. He unveiled his "45 by 15" plan that calls for New York to meet 45 percent of its electricity needs through improved energy efficiency and clean renewable energy by 2015. This goal will alsocreate 50,000 new jobs for New Yorkers, helping build the workforce necessary for a clean energy economy. Governor Paterson also announced the creation of a consortium on hybrid electric batteries and energystorage technologies to make strides in the development of technology for plug-in hybrid electric vehicles.

New York State is a leader in taking action to address climate change and is implementing a broad portfolio of tactics to reduce greenhouse gas emissions, from promoting energy efficiency, conservation, and renewable energy programs to participating in the nation's first mandatory carbon cap-and-trade program for power plant emissions. As part of this proactive approach, the New York State Legislature established the State Sea-Level Rise Task Force in 2007, under a bill sponsored by Senator Carl Marcellino and Assemblyman Robert Sweeney. The task force will issue a report making recommendations toprotect New York's coastal ecosystems, natural habitats, infrastructure, and coastal communities from flooding and other potential impacts.

The task force is comprised of state agencies, local governments, not-for-profit organizations, community groups, and private citizens. Commissioner Grannis serves as chair of the task force.

The geographic scope of the task force report will include the five boroughs of New York City and the counties of Westchester, Nassau, and Suffolk. The tidal waters of the Hudson River to the Federal Dam at Troy are also included because of the potential risks from rising waters to Hudson River ecosystems, drinking water supplies, and infrastructure.
