This page, Massachusetts Sea Level Rise and Coastal Flooding Viewer, is, in the scale of 1, Strongly Disagree, to 5, Strongly Agree, Professional Training & Career Development, Massachusetts Office of Coastal Zone Management, Shoreline Change - Maps, Data, and Guidance on Erosion and Accretion Rates, Assessing Vulnerability of Coastal Areas and Properties. The viewer and technical report are designed as a general vulnerability assessment and planning tool. Over the next 30 years, the study finds 1,100 homes in Revere could face flooding every other week. Dahl says that could be the subject of future research. This indicator comprises several metrics to describe past and future sea level rise globally and in European seas. Using data from scores of stations around the world, scientists can calculate a global average and adjust it for seasonal differences. If nothing is done to curb greenhouse gas emissions from their current levels — and if the world as it's known to climate scientists doesn’t shift in some dramatic way — the coastal communities of Massachusetts could face a grim reality. The Social Vulnerability Index , which shows areas of high human vulnerability to hazards, is based on population attributes from Census ⦠This map viewer illustrates the scale of potential coastal flooding after varying amounts of sea level rise. More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017,: 1554 which is a trend of roughly 30 cm (12 in) per ⦠Homes; The team also looked at whether the threat of sea level rise could disproportionately affect blacks and Hispanics and less affluent areas generally. This product should not be used for legal, engineering, or surveying purposes. The online viewer includes these sections: With the viewer, users can zoom in to an area of interest and then switch tabs to compare coastal flood data. The Curbside Compost Program will expanded to all buildings with 1 to 12 units on April 2. The near term forecast is less daunting, but should still serve as a wakeup call. The present value of these costs ranges from 0.17 to 3.08 million US$ depending on the sea level rise scenario. Things below in. Select any of the water levels on the left depict four levels of flooding: 0 feet is today's sea level. Water level. Video. Confidence (80%) of the mapped inundation area is also available and is based on the accuracy of the elevation data and the mean higher high water tidal surface. Nationally, sea levels have risen 6.5 inches since 1950. The community facilities and infrastructure mapped in the viewer are identified with an icon and facility outline. By 2050, sea-level rise will push average annual coastal floods higher than land now home to 300 million people, ... Boston, Cambridge, Quincy are all high risk areas. The Curbside Compost Program will expanded to all buildings with 1 to 12 units on April 2. The study suggests that if nothing changes, some 90,000 homes valued at $63 billion could face chronic flooding by the end of the century — and that’s just in Massachusetts. Sea level rise is increasing. ... Cambridge MA 02138, USA (617) 547-5552. Top-requested sites to log in to services provided by the state. Some 6,500 people live in these “at-risk” homes, according to the study. The study — "Underwater: Rising Seas, Chronic Floods, and the Implications for US Coastal Real Estate" — was overseen by climate scientist Kristy Dahl of the Union of Concerned Scientists. The measurements are also important for understanding overall sea level rise due to global warming that scientists warn is a risk to ⦠Select tide gauges within the U.S. where at least 30 years of hourly water level data are available also give flood risk projections which integrate sea level rise, based on methods described in more recent research (Tebaldi et al. sea level definition: 1. the average height of the sea where it meets the land: 2. the average height of the sea whereâ¦. 2050 Sea Level Rise; 2100 Sea Level Rise; 2050 Sea Level Rise + Major Storm; 2100 Sea Level Rise + Major Storm; TEXT. Given a moderate scenario for sea level rise, many Cape May coastal communities could see 15 percent or more of their land flooded 26 times or more per year, or every other week, on average, by the middle of the century. Tide gauge stations from around the world have measured the daily high and low tides for more than a century, using a variety of manual and automatic sensors. Change in Chlorophyll-a Concentration, v1 ( 1998 â 2007 ) Indicators of Coastal Water Quality The new study looks strictly at the threat posed by sea level rise, without taking into consideration the more complicated factors of storms and rain-induced flooding. A look at different solutions, and their timelines, that cities have turned to in response to sea level rise. (617) 626-1178. Modeling Sea Level Rise and Storm Surge Impacts from Climate Change Purpose The purpose of this report is to present key findings of sea level rise (SLR) and storm surge modeling for the City of Cambridge, and to summarize the two technical memoranda provided by the Woods Hole Group and MWH Global that ⦠Cambridge will become a seaside town by 2100 if rising sea levels continue as predicted, say the Met Office. So her team took the latest climate data (the 2014 National Climate Assessment), and mixed it with the latest housing data (Zillow), to quantify and locate the threat of sea level rise. Flooding has increased by an average of 233% in the last 20 years. “We knew that the data existed to understand this risk better, and so we wanted to analyze that data so that people are more able to see the threat clearly,” Dahl said. Site-specific assessments of elevations or boundaries (parcel, structure, or other) should be made by a certified survey professional. CZM developed the Sea Level Rise and Coastal Flooding Viewer to support the assessment of coastal flooding vulnerability and risk for community facilities and infrastructure, consistent with Governor Bakerâs Executive Order 569.
