New York State’s, offered in three specific, geographically bounded neighborhoods, requires that the land procured be preserved as open space. The City’s acquires any substantially damaged properties, with the goal of redeveloping them as more resilient housing.

  • Guidelines for Storm Preparedness
    Eleven Days after Hurricane Carol slammed the Island in August 1964, Hurricane Edna struck on September 11, flooding Edgartown (Vineyard Gazette Archive) Guidelines for Storm Preparedness West Tisbury Climate Action Committee May 2020 May 3-9, 2020: Hurricane Preparedness Week National Weather Service 1 of 11 Storm Preparedness It should come as no surprise that Martha’s Vineyard is vulnerable Nor’easter storms formed over the cold Atlantic between September and April; and hurricanes formed over warm tropical waters from June to November. The absence of hurricanes in recent years have lulled some into thinking they are no longer a serious threat to the Vineyard. The truth is that storms and hurricanes will lash the Vineyard, flooding low-lying portions of our villages, uprooting trees, bringing down power lines, snatching boats from their moorings, and disruption ferry service to the mainland. It is not a question of if; it is a matter of when and with what degree of severity. What is equally sure is that with a modicum of preparedness, your chances of riding out a storm and coping with the inevitable disruptions in the aftermath — the loss of power, telephone and internet connections, and delayed resupplying from the mainland — increase substantially. This manual breaks down emergency preparedness into stages; What you can do immediately without a storm in sight. What you can do when you know a storm is on its way. And, what you can do to make your surroundings as safe as possible when the storm hits. Storm risk varies by the size and path of the storm and by the population of the Vineyard.

  • Hurricane and Tropical Storm
    State of New Jersey 2014 Hazard Mitigation Plan Section 5. Risk Assessment 5.8 Hurricane and Tropical Storm 2014 Plan Update Changes The 2014 Plan Update includes tropical storms, hurricanes and storm surge in this hazard profile. In the 2011 HMP, storm surge was included in the flood hazard. The hazard profile has been significantly enhanced to include a detailed hazard description, location, extent, previous occurrences, probability of future occurrence, severity, warning time and secondary impacts. New and updated data and figures from ONJSC are incorporated. New and updated figures from other federal and state agencies are incorporated. Potential change in climate and its impacts on the flood hazard are discussed. The vulnerability assessment now directly follows the hazard profile. An exposure analysis of the population, general building stock, State-owned and leased buildings, critical facilities and infrastructure was conducted using best available SLOSH and storm surge data. Environmental impacts is a new subsection. 5.8.1 Profile Hazard Description A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or sub-tropical waters and has a closed low-level circulation. Tropical depressions, tropical storms, and hurricanes are all considered tropical cyclones. These storms rotate counterclockwise in the northern hemisphere around the center and are accompanied by heavy rain and strong winds (National Oceanic and Atmospheric Administration [NOAA] 2013a). Almost all tropical storms and hurricanes in the Atlantic basin (which includes the Gulf of Mexico and Caribbean Sea) form between June 1 and November 30 (hurricane season). August and September are peak months for hurricane development.

  • Understanding Our Coastal Environment
    Preface The South Carolina Beachfront Management Act In the Beginning The Coastal Zone Management Act of 1977 was enacted to protect our coastal resources from unwise development. This legislation served the beaches well during its first decade, but as South Carolina became a more popular tourist destination, it became apparent that the portion of the Act that dealt with beaches was inadequate. As development crept seaward, seawalls and rock revetments proliferated, damaging the public’s beach. In many areas there was no beach left at high tide. In some areas, there was no beach at low tide, either. In 1988 and again in 1990, South Carolina’s legislators took action and amended and strengthened the Coastal Zone Management Act. The resulting Beachfront Management Act protects South Carolina’s sandy shores by increasing the state’s jurisdiction and encouraging development to move landward. South Carolina’s Beachfront Jurisdiction To find the boundaries of this jurisdiction, staff from the Office of Ocean and Coastal Resource Management must first locate the baseline, which is the crest of the primary oceanfront sand dune. Where there are no dunes, the agency uses scientific methods to determine where the natural dune would lie if natural or man-made occurrences had not interfered with nature’s dune building process. The setback line is the most landward boundary and is measured from the baseline. To find the depth of the setback line, the beach’s average annual erosion rate for the past forty years is calculated and multiplied by forty. For example, if the erosion rate is one foot per year, the results will be a setback line that stretches forty feet from the baseline.

  • Richmond, VA Hurricanes
    Hurricanes Influencing the Richmond Area Why should residents of the Middle Atlantic states be concerned about hurricanes during the coming hurricane season, which officially begins on June 1 and ends November 30? After all, the big ones don't seem to affect the region anymore. Consider the following: The last Category 2 hurricane to make landfall along the U.S. East Coast, north of Florida, was Isabel in 2003. The last Category 3 was Fran in 1996, and the last Category 4 was Hugo in 1989. Meanwhile, ten Category 2 or stronger storms have made landfall along the Gulf Coast between 2004 and 2008. Hurricane history suggests that the Mid-Atlantic's seeming immunity will change as soon as 2009. Hurricane Alley shifts. Past active hurricane cycles, typically lasting 25 to 30 years, have brought many destructive storms to the region, particularly to shore areas. Never before have so many people and so much property been at risk. Extensive coastal development and a rising sea make for increased vulnerability. A storm like the Great Atlantic Hurricane of 1944, a powerful Category 3, would savage shorelines from North Carolina to New England. History suggests that such an event is due. Hurricane Hazel in 1954 came ashore in North Carolina as a Category 4 to directly slam the Mid-Atlantic region. It swirled hurricane-force winds along an interior track of 700 miles, through the Northeast and into Canada. More than 100 people died. Hazel-type wind events occur about every 50 years. Areas north of Florida are particularly susceptible to wind damage.
