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.

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.

EXECUTIVE SUMMARY Encroaching Tides How Sea Level Rise and Tidal Flooding Threaten U.S
EXECUTIVE SUMMARY Encroaching Tides How Sea Level Rise and Tidal Flooding Threaten U.S. East and Gulf Coast Communities over the Next 30 Years HIGHLIGHTS Today scores of coastal communities in the United States are seeing more frequent tidal flooding. And as global warming drives sea levels higher over the Sea level rise is visible today in communities next 15 to 30 years, flooding from high tides is expected to occur even more often up and down our coasts in the form and cause more disruption, particularly on the East Coast and, increasingly, on of increased tidal flooding. Given the the Gulf Coast. This flooding will redefine how and where people in affected areas live, work, and otherwise go about their daily lives. Coastal communities, accelerating rate at which sea levels and the nation as a whole, need to start planning today to cope with sea level rise are rising, the reach of the tides is poised and unprecedented tidal flooding, and to take swift and decisive action to limit longer-term damage to our coasts. to grow substantially. Our analysis explores projected changes in tidal flooding A Daily Cycle Gains Disruptive Force under a mid-range scenario of sea level High tides are having a greater impact on U.S. communities today than in decades rise, and the implications for East and past for two reasons. First, our shores are more heavily developed, so higher tides Gulf Coast communities in the absence of affect more people and infrastructure. Second, these tides are now occurring on top of elevated—and rising—sea levels.

Solutions to Coastal Flooding: Can National Parks Turn the Tide?
Solutions to Coastal Flooding: Can National Parks Turn the Tide? Cliff McCreedy Coastal regions of the US have experienced rapid population growth and environmen- tal change over the last half century. More than 39% of the US population, or over 123 million citizens, now live in coastal shoreline counties.1 Residential and commercial development has taken up coastal lands and consumed water resources that formerly provided ecosystem services. As a result, coastal systems and communities are now more vulnerable to flooding. While the reasons for flooding are not new—storm inundation, extreme precipitation, and tidal flooding—they are worsening in many areas due to development, rising sea levels, and stronger storms. Significant resources and assets in 80 ocean and coastal parks are located in low-lying ar- eas of the coast where various parks and adjacent communities have suffered storm damage, and concerns about storm surge, erosion, and tidal flooding remain high. At the same time, ecosystem services in the national parks, national wildlife refuges, and state parks provide various levels of natural resilience to coastal flooding, such as drainage and dissipation of storm surge and flood waters via beaches, wetlands, and soils, and wave dissipation via oyster reefs and coral reefs. In many places, these public lands offer rare, undeveloped shorelines along our densely populated coasts, providing the public with significant recreational and economic benefits in addition to natural flood control. The National Park Service (NPS) is tasked by Congress to preserve natural and cultural resources unimpaired and provide recreational opportunities, as well as maintain these nat- ural floodplain values of parks.
