Executive Summary Maryland House Bill 1350/1472 requires each coastal community that experiences nuisance flooding to prepare a Nuisance Flood Plan, to inform the public, and to take action in support of community resilience. Elements of the plan must include: • Inventory of nuisance flood areas • Thresholds for warning and response • Documentation of Events and Response Activity Ocean City MD experiences periodic nuisance flooding conditions (up to 1 foot deep* that cause inconvenience but not significant property damage). Nuisance flooding does not affect Ocean City uniformly – first to flood (lowest elevation) areas have been identified, along with areas that experience limited storm drainage capacity (flooding with heavy rainfall/flash flooding). Downtown streets along the bayside between the Inlet and 4th Street are the most frequently impacted, and create the greatest nuisance especially during the active tourist season. -

Tidal Flooding and Coastal Adaptation Responses in Pekalongan City
E3S Web of Conferences 202, 06027 (2020) https://doi.org/10.1051/e3sconf/202020206027 ICENIS 2020 Tidal flooding and coastal adaptation responses in Pekalongan City * Andrea Ramadhani Maharlika , Sudharto Prawata Hadi, Kismartini, and Ade Lenty Hoya Environmental Sciences, Postgraduate School, Diponegoro University, Semarang, Indonesia Abstract. Over the past 10 years, the coastal region of Pekalongan City has experienced the phenomenon of tidal flooding and has almost submerged coastal areas almost daily. At present, tidal floods have submerged 51% of the total area of Pekalongan City with a maximum inundation height of 1.1 meters. As a result, there has been damage to the economic, social, and physical (infrastructure). Adaptation response from all parties involved is needed to reduce negative impacts. The writing of this manuscript aims to find out the phenomenon of tidal flooding and the government's adaptation response together with the community in the coastal area of Pekalongan City. Lots of research on this issue, but in this manuscript focus on structural and non-structural adaptation responses. Data collection techniques in the study of literature and documentation. The results of the study showed that the tidal flooding in the coastal area of Pekalongan City in addition to sea-level rise and topography, this condition was also exacerbated by the phenomenon of land subsidence which reached minus 30-50 cm. Non-structural adaptation response by establishing disaster response organizations and disaster prepared posts, while early warning systems and flood control infrastructure are forms of structural adaptation responses. Keywords: Tidal flooding, Structural adaptation, Non-structural adaptation 1 Introduction Pekalongan City is one of the cities in Central Java which is located on the Northside of Java Island. -

Sea Level Rise: the City of Fort Lauderdale Is Taking It Seriously – but Often, Fighting the Effects of Climate Change Can Be a Lonely Job
By: Mike Seemuth Jul. 1, 2016 Sea Level Rise: The City of Fort Lauderdale is taking it seriously – but often, fighting the effects of climate change can be a lonely job. Periodic floods due to the Atlantic Ocean’s high tides, especially the annual king tides in fall, have become a soggy fact of life in Fort Lauderdale. In September 2015, king-tide flooding left standing water on Las Olas Boulevard and side streets for several days. Some owners of posh Las Olas shops barricaded their businesses with sandbags. That was mild compared to damage done in October 2012 when king tides coincided with powerful waves propelled by Hurricane Sandy offshore, eroding big chunks of the city’s northern beach, shattering a sidewalk, knocking down traffic signals and ripping asphalt off A1A. The street was so badly damaged that residents of the Finger Streets neighborhood just west of A1A – the only road into and out of the neighborhood – were unable to leave their homes by car for five days. Yet we may look back on this flood-prone era as the good old days. As sea level rises, periodic flooding in low-lying areas of Fort Lauderdale could give way to permanent inundation. “What we’re seeing with these tidal flooding events now could be a permanent condition going forward,” says Nancy J. Gassman, assistant public works director of the City of Fort Lauderdale. For planning purposes, the City of Fort Lauderdale has adopted a projection that sea level will rise 3 to 7 inches by 2030. “And if we look out to 2060, 2 feet of sea level rise is likely, and even higher than that is possible; 34 inches by 2060 is a possibility,” says Gassman, who heads the sustainability division of the city’s public works department. -

Our strategy calls for combining public investment, a secure social safety net, and fiscal discipline. In that framework, the Project puts forward innovative proposals from leading economic thinkers — based on credible evidence and experience, not ideology or doctrine — to introduce new and effective policy options into the national debate. The Project is named after Alexander Hamilton, the nation’s first Treasury Secretary, who laid the foundation for the modern American economy. Hamilton stood for sound fiscal policy, believed that broad-based opportunity for advancement would drive American economic growth, and recognized that “prudent aids and encouragements on the part of government” are necessary to enhance and guide market forces. -

BOWER A thesis submitted in partial fulfillment of the requirements for the Honors in the Major Program in Environmental Engineering in the College of the Engineering and Computer Science and in the Burnett Honors College at the University of Central Florida Orlando, Florida Fall Term 2019 Major Professor: Thomas Wahl, Ph.D. ABSTRACT Millions of people in low-lying areas are already affected by flooding, and the number will increase substantially in the future. Tidal flooding, the form of flooding caused by a combination of high tides and sea level rise to overcome protection levels, can cause damage and inconveniences such as road closures, overwhelmed drainage systems, and infrastructure deterioration from water damage. Tidal flooding already occurs annually in cities along the U.S. east coast, most notably Miami. However, the time it will take for other regions globally to begin to experience tidal flooding has not yet been assessed.
