Recommendations to the Secure Commonwealth Panel on the Issue of Sea Level Rise and Recurrent Flooding in Coastal Virginia
September 5, 2014
From the Recurrent Flooding Sub-Panel of Virginia’s Secure Commonwealth Panel, this draft report provides recommendations on actions Virginia can take to prepare for sea level rise and increased flooding as caused by climate change. This comprehensive report also offers analysis of which tools, authorities, initiatives and resources already exist, what actions can be taken, and how to coordinate it all into a united effort to adapt to these impacts.

Danish Road Directorate - Blue Spot Analysis
September 2014
The Danish Road Directorate (DRD) developed a Blue Spot Analysis to identify roadways vulnerable to flooding under present conditions and future climate projections and to inform its climate change adaptation response. A “Blue Spot” is a section of road where there is both a high risk of flooding and significant consequences from flooding. Road flooding is the primary climate adaptation challenge for Denmark and is the focus of the DRD’s climate adaptation planning. The DRD’s strategy to adapt to road flooding is to manage flooding that occurs, improve roads when financially feasible, and to prevent climate-related impacts whenever possible.

EPA Flood Resilience: A Basic Guide for Water and Wastewater Utilities
September 2014
The U. S. Environmental Protection Agency (EPA) developed this guide to help drinking water and wastewater utilities become more resilient to flooding. In the approach, the utility would examine the threat of flooding, determine impacts to utility assets and identify cost-effective mitigation options. A simple, 4-step assessment process is outlined to help water utilities understand their flooding vulnerability and identify practical mitigation options to protect critical assets. The guide is particularly useful for small and medium utilities.

Designing with Water: Creative Solutions from Around the Globe
August 1, 2014
Developed by The Boston Harbor Association (TBHA) and Sasaki Associates, this report focuses on urban design solutions to sea level rise resulting from climate change. Designing with Water provides Boston-relevant case studies and innovative designs for city planners and developers to adapt to flooding and enhance urban resiliency. The report is the second in the Preparing for the Rising Tides series, which the TBHA first released in 2013, assessing the neighborhood-level sea level rise flooding risk to Boston.

Sea Level Rise and Nuisance Flood Frequency Changes Around the U.S.
June 2014
This technical report from National Oceanic and Atmospheric Administration (NOAA) describes the increased rate and severity of recurrent coastal flooding events as related to sea level rise. It also addresses what climatic patterns are associated with year-to-year differences in flooding, and during what season nuisance floods typically occur and why.

Prince George's County, Maryland Repetitive Loss Area Analysis Report
2014
In 2014, Prince George’s County, a Class 5 Community Rating System (CRS) community, prepared a repetitive loss area analysis (RLAA) report through its Department of Environmental Protection. CRS is a voluntary program administered by the Federal Emergency Management Agency (FEMA) under the National Flood Insurance Program that allows participating local governments to earn discounts on their residents’ flood insurance premiums. Prince George's County commissioned the report to inform the development of its hazard mitigation plan due to an increase in the number of repetitive loss properties in the county.

North Carolina Flood Risk Information System
May 19, 2014
In North Carolina, the state developed a Flood Risk Information System to improve the accuracy and functionality of the state's floodplain maps, and to help local governments and state agencies make decisions about how to reduce flood losses (or mitigate flood risks). The state digitized the floodplain maps developed by Federal Emergency Management Agency (FEMA) using high-resolution LiDAR data for the entire state, and developed this System to make the maps more accurate and easier to use. This System incorporates additional data layers not included on FEMA floodplain maps - such as flood depth damage information determined from building footprints, parcel information, and first floor elevations.

The Prevalence and Cost of Urban Flooding
May 2014
Investigating Cook County, Illinois as a case study, this report assesses the financial cost related to urban flooding between 2007-2011. Urban flooding as described here can include overflow from rivers and streams, sewage pipe backups, water seepage through building walls and floors, and stormwater accumulation. Cook County is primarily urban and densely populated with the City of Chicago making up approximately 54% of the population. The study found that urban flooding is chronic and often repetitive in this county, costing a total of $773 million in insurance claims over five years.

Floods in Boulder: A Study of Resilience
April 2014
This research examines a potentially catastrophic flooding event in Boulder, Colorado in September 2013. Though the scale of flooding was unprecedented, “only” 10 lives were lost, most infrastructure was maintained, and the recovery has been considered successful. In this study, the Institute for Social and Environmental Transition (ISET) examines Boulder’s demonstrated flood resilience, and how the physical and human systems, as well as legal and cultural norms played into Boulder's flood response.
