This climate resilience plan was created collaboratively by Greater Miami and the Beaches (GM&B) – a unique partnership between Miami-Dade County, the City of Miami, and the City of Miami Beach. The unified adaptation strategy integrates climate change planning and preparedness for the low-lying coastal communities in southeast Florida (which share area code 305). The Resilient305 Strategy offers 59 action items that will help municipalities to better prepare for and respond to increasing occurrences of hurricanes, sunny day flooding, and sea level rise, as well as social and economic inequities.
In June 2019, the Norfolk City Council adopted a policy authorizing the creation of Special Service Districts (SSD) to support implementation of local flood risk reduction and water quality improvement projects in the City of Norfolk, Virginia. SSDs enable a group of residents to agree to pay a tax to finance additional services in a particular neighborhood. The Norfolk policy allows SSD funding to be used to pay for flood mitigation, dredging, water quality improvements, and coastal protection projects.
NOAA’s fifth annual update of the State of Coastal High Tide Flooding (HTF) provides HTF projections to inform adaptation and decision-making for the following year, and over the longer term. High tide flooding (aka ‘sunny day’ or ‘nuisance’ flooding) occurs when water levels measured at NOAA tide gauges exceed heights based on the minor-flood thresholds set by NOAA’s National Weather Service. This report updates high tide flood frequencies during 2018 (based on the meteorological year: May 2018-April 2019) at 98 NOAA tide gauge locations, and provides a statistical outlook for 2019 (May 2019 – April 2020).
Maine Governor Janet Mills signed into law LD 563, “An Act to Help Municipalities Prepare for Sea Level Rise” in May 2019. The law amends the State’s growth management and local land-use planning requirements (at Title 30-A, Chapter 187 of the Maine Code) to address the effects of sea-level rise. It allows coastal municipalities and “multimunicipal” regions including coastal municipalities to consider sea level rise projections and potential effects on buildings, transportation infrastructure, sewage treatment facilities, and other municipal or private facilities.
From the San Francisco Estuary Institute (SFEI) and the San Francisco Planning and Urban Research Association (SPUR), the San Francisco Bay Shoreline Adaptation Atlas offers nature-based coastal climate resilience strategies for the San Francisco Bay Area region of California. The Atlas presents a new view of the Bay area in a map divided into areas with common physical characteristics for which specific adaptation strategies can be developed to prepare for sea level rise. The report is intended to inform the regulatory community, regional governments, landscape designers, planners, developers, engineers, and other members of local communities in coordinating and planning for regional resilience – including flood control, transportation, parks, land use, and ecosystem restoration.
The Texas General Land Office (GLO) updated Coastal Resiliency Master Plan provides a framework for the protection and adaptation of coastal infrastructure and natural resources across the most vulnerable regions of the Texas Gulf coast. The Resiliency Plan adopts the most current storm surge and sea level rise models to determine the implication of projected climate impacts, coastal hazards, and prioritization of these projects. The priority issues of concern identified for resilience planning on the Texas coast focus on degraded or lost habitat, beach and dune erosion, storm surge, coastal flooding, impacts on water quality and quantity, loss of marine and coastal resources, and shoreline debris.
Mexico Beach is on the Gulf of Mexico in Bay County, Florida and faces climate enhanced hurricanes, coastal storm surge, sea level rise and flooding impacts. In October 2018, Hurricane Michael, a Category 4 storm, made landfall in Mexico Beach demolishing 70% of the town’s homes. The coastal community has amended the Federal Emergency Management Agency (FEMA) flood zones maps to reflect storm surge flood levels and high risk floodplain areas as implicated by Hurricane Michael flooding. An ordinance has been adopted in which new construction in Mexico Beach must be elevated at least a foot and a half higher than FEMA’s base-level flood predictions in both the region’s 100-year and 500-year floodplains.
This report issued by the U. S. Geological Survey and the U. S. Department of the Interior quantifies the value of U. S. coral reefs in protecting people and infrastructure from coastal hazards that will be exacerbated by climate change and sea-level rise including extreme weather events, flooding, and erosion. The report is intended to inform stakeholders and decision-makers of the value of coral reefs in reducing risk from coastal hazards, and to provide quantitative data that can be used to consider the role coral reefs should play in adaptation and risk mitigation planning.
The Eastern Shore Land Conservancy partnered with the Georgetown Climate Center (GCC), the Eastern Shore Regional GIS Cooperative, and the University of Maryland Environmental Finance Center for this analysis on sea level rise preparedness in Maryland’s Eastern Shore region. GCC offers a discussion of strategies related to floodplain, zoning and regulatory standards to support sea level rise and coastal flooding resilience policies and decision making.
The Regional Resilience Exposure Tool (R2ET) is an interactive mapping tool that illustrates current and projected coastal flooding risks to resources in the Northeast Florida region. The types of flooding mapped are FEMA flood hazard zones, storm surge, depth of flood at defined storm occurrence intervals, and sea level rise at defined water levels. Users can select data layers for resources to overlay on flooding layers including critical facilities, priority wildlife species, and vulnerable populations.
