By Emily Underwood, EOS, August 20, 2018 "Not all floods are deadly disasters. As anyone who has ever waded through a flooded Washington, D.C., subway station can attest, many floods are merely bothersome, tangling public transportation and causing other daily hassles. As sea levels rise and populations grow, such “nuisance floods” are growing more frequent. A new study proposes a global definition for such floods, in the hope of helping governments, cities, and insurance companies plan for them and cope with rising costs."

Policy makers need to seriously consider how to accurately communicate increasing flood risks to the public. Reverting to old flood maps and granting variances to promote development is a recipe for more disasters down the road."

Some of the information is specific to the State of Massachusetts but most of it is applicable on a national level, as it pertains to FEMA. Some of the topics covered are: how flood zones are mapped, limitations of Flood Insurance Rate Maps, delineating V Zones in Primary Frontal Dunes, and requesting changes to FIRMs. Click here to download a PDF of the publication! | Climate Change, Extreme Precipitation, and Flooding: The Latest Science The Union of Concerned Scientists has compiled an informative and easy-to-read synopsis of the "latest scientific findings on how and why precipitation and flooding patterns have changed in the United States, a summary of possible future scenarios, and recommendations for how to make communities more flood-resilient." This report focuses primarily on the flooding inland areas.

NGVD 1929 is used as the reference datum on many Flood Insurance Rate Maps (FIRMs). It provides a vertical control for surveying and engineering, for measuring elevations above and below mean sea level. Newer, digital Flood Insurance Rate Maps reference the North American Vertical Datum (NAVD) of 1988.
