City: New York Country / US State / US Territory: New York Type of Solution: Seawalls and Living Shorelines Climate Impact: Seal Level Rise; Hurricanes and Storm Surge; Extreme Precipitation and Flooding Social Value Created: Educational and Career Development Opportunities; Active Living and Recreation; Community Engagement; Social Cohesion; Arts and Culture Cost: $60 million Funding Source: U.S. Department of Housing and Urban Development Rebuild by Design competition
Living Breakwaters is a project aimed at helping to reduce wave energy, lowering flooding risks during extreme storm events. The project was developed by SCAPE landscape Architecture for the Rebuild Design Competition, a competition held by the U.S. Department of Housing and Urban Development (HUD) to improve coastal resilience in response to Hurricane Sandy.
The Living Breakwaters approach uses structures to restore and enhance marine habitats, as well as improve biodiversity. Structures include reef ridges, reef streets, crenulated crests, and bio-enhancing concrete. This habitat mimics historic oyster reefs, which helps to restore the oyster population.
Additionally, the project co-creates social value. The project will help to prevent beach erosion and protect property values. The project also will improves access to the shoreline an recreational opportunities such as boating and fishing.
Also, an on-land Water Hub will be constructed on shore for visitoring groups, recreation, and educational programs. The Harbor School and Billion Oyster Project will create educational opportunities for local schools to learn about ecological stewardship and how they can help to protect Staten Island’s coastline. Implementation of the project also provides educational opportunities for research and skill development through project monitoring.
City: New York Country / US State / US Territory: New York Type of Solution: Canal Climate Impact: Extreme Precipitation and Flooding Social Value Created: Water Security and Quality; Public Health and Safety; Public Space; Active Living and Recreation Cost: $1.5 million Funding Source: Public health; access to public space; water quality; recreation; redevelopment and brownfields
In 2010, the canal was named an EPA Superfund site, and the Sponge Park project emerged as a solution that would not only remediate the site and prevent future pollution but also improve access to a number of public spaces. Currently, the NYC area does not meet federal water quality standards for swimming, fishing, and wildlife habitats due to its inability to prevent pollution, particularly sewer overflows during heavy rain events. The water quality poses a health hazard to community members.
Gowanus Canal Sponge Park was built to manage stormwater, helping to slow, absorb, and filter polluted surface water runoff. Street runoff is captured and stored in underground tanks, which are then filtered by artificial wetlands and then released into the canal. The park is estimated to capture and treat 1 million gallons of storm water annually. This project will help to improve water quality in the surrounding waterways for recreational use and protect wildlife habitat.
The New York City Department of Environmental Protection (DEP) and Department of Design and Construction also built 70 curbside rain gardens in South Brooklyn. These additional rain gardens can manage 133,000 gallons of stormwater runoff and will capture an estimated 6 million gallons of stormwater runoff annually. Long-term, the project aims to create 11.4 acres of revitalized canal space, 7.9 acres of public spaces and 3.5 acres of remediated wetland basins.
City: New York Country / US State / US Territory: New York Type of Solution: City Government Program Climate Impact: Hurricanes and Storm Surge; Extreme Precipitation and Flooding Social Value Created: Food security and nutrition; community cohesion, bikeability; livability; urban beautification
The Cloudburst Study was conducted by NYC through a collaborative project with Copenhagen to prevent flooding during heavy precipitation events, aka. Cloudbursts. NYC and Copenhagen are both facing rising sea levels and Cloudbursts, so the cities have partnered to develop new innovative projects to enhance stormwater management. Their solutions are aimed at creating inspiring urban areas and other co-benefits for citizens, local businesses, and the city.
South Jamaica Houses redevelopment is one pilot project that has emerged from the NYC Cloudburst Study. The project will increase liveability of the area, and will result in additional shared green space for recreation, bike paths, and urban gardening. Improved public spaces will help to improve community cohesion. Additionally, the college will be better integrated into the surrounding community, also contributing to social cohesion.
City: New York Country / US State / US Territory: New York Type of Solution: City Government Program Climate Impact: Seal Level Rise; Hurricanes and Storm Surge; Extreme Precipitation and Flooding Social Value Created: Affordable and Safe Housing; Social Justice and Equity for Vulnerable Communities; Public Health and Safety
The Built It Back Program was started after Hurricane Sandy struck in 2012. The Program provided homeowners, landlords, and tenants in low- and middle-income neighborhoods affected by the storm with funds sustainably rebuild homes. The goal of the program is to help vulnerable communities rebuild their homes and be better prepared for future hurricanes.
Homes must be rebuilt above Base Flood Elevation level and must be certified by Enterprise Green Communities, a certification for sustainable and energy efficient buildings, to improve communities’ resilience to flooding and Sea Level Rise. In addition to assistance in reconstructing homes, the Program funded legal counseling and temporary housing for residents affected.
The Program received 20,000 applications, and 16,000 completed the initial eligibility review. As of June 2018, the program has helped 12,500 households through reimbursement checks, construction starts, and acquisitions
City: Miami Country / US State / US Territory: Florida Type of Solution: Awareness Campaign Climate Impact: Sea Level Rise Social Value Created: Public Education; Community Engagement; Social Justice and Equity for Vulnerable Communities; Public Health and Safety
During King Tides, groundwater rises and seeps up into low-lying communities. While currently these events only occur a few times a year, they could occur as frequently as 30 to 40 times a year by 2030. Florida International University (FIU) is leading a volunteer program to help map and collect data on these King Tides, helping to inform adaptation solutions.
Local community members volunteer for a few hours during these King Tides to take and record measurements in a phone application, recording the depth, length, and location of the King Tide. This method improve community awareness and helps to engage community members in solution development.
One of these sampling events, Sea Level Solutions Day, occurred on November 4, 2017. Over 75 citizen scientists volunteered, assisting in sampling in six different Miami neighborhoods. Samples were taken for traces of fecal coliform and other indicators of contamination.
City: Washington Country / US State / US Territory: D.C. Type of Solution: Roof Climate Impact: Extreme Temperatures and Urban Heat Island Effect Social Value Created: Educational and Career Development Opportunities; Employment Opportunities; Public Health and Safety
Washington, D.C. has a Smart Roof Program that was implemented to counteract the Urban Heat Island (UHI) effect. The program integrated roof asset and energy management projects to retrofit roofs of 435 buildings, totalling 321 acres of roof area, including schools, police stations, fire stations, park and recreation centers, and office buildings.
Program objectives include energy conservation, stormwater management, heat reflection, solar energy production, carbon management, and leading through use of best practices and community involvement. The Washington, D.C. Department of General Services is projected to save $33 million over 20 years and will result in a reduction of 20,000 metric tons of CO2e annually. Additionally, the project addressed safety issues of the aging roofs.
The program focused on two types of roofs: vegetative (green) roofs and cool roofs. Vegetative roofs are used to teach students about botany, and solar PV installations on cool roofs are used as vocational education for students on renewable energy technologies through the DC Greenworks apprenticeship program. Projects were also used to support job creation and training in the local community.
City: Tampa Country / US State / US Territory: Florida Type of Solution: Agriculture Climate Impact: Invasive Species and Pests Social Value Created: Food Security and Nutrition; Living Wages Cost: N/A Financing: N/A
Fungus is common in Florida’s humid climate that will rot strawberries, and may become a larger problem in the future. To avoid rot, farmers overspray strawberries, costing them time and money. Additionally, the fungus may develop a resistance to the fungicide if the chemicals are sprayed too frequently. A system was developed to monitor temperature, leaf wetness, humidity and local weather to alert farmers when they should be spraying fungicide.
Improving crop yields and reducing fungicide use reduces operational costs, helping to ensure living wages for farmers. Improving crop yields also supports food security and nutrition, and reducing fungicide use reduces the environmental impact of agricultural practices. Additionally, customers have started to demand more natural strawberries, and reducing chemical use helps to meet customer expectations.

City: Tampa Country / US State / US Territory: Florida Type of Solution: Buildings and Housing Climate Impact: N/A Social Value Created: Public safety; public health; benefits vulnerable communities (including low-income and elderly populations); education; arts and culture; redevelopment Cost: $2 billion Financing: $28 million stimulus grant
A unique mixed-use redevelopment in Tampa Florida. The development includes a combination of multifamily housing, senior housing, retail, and office space that meets the criteria for the Leadership in Energy and Environmental Design (LEED) Gold certification. All of the housing is also classified as “affordable” housing. Previously, the space was a public housing development that was isolated from the broader community. The new development will increase community connectivity.
Green infrastructure is a major feature of the new development, helping to manage stormwater. A 33,000 cubic foot water-retention vault is being installed 12 feet underground. The vault is a very unique stormwater management system, collecting and treating water using nutrient separating baffle boxes and sediment chambers to remove pollutants from the water. Then, the water is stored and used for irrigation on-site. Any water exceeding the vault’s capacity is treated and released to Tampa Bay.
The site also includes permeable pavers and native plants, increasing groundwater infiltration of stormwater and reducing water demands landscaping. Additionally, there is a 16,000 square foot Technology Park above the stormwater vault that includes educational kiosks, solar public art, and the district chiller.
City: Seattle Country / US State / US Territory: Washington Type of Solution: Vacant Properties and Lots Climate Impact: Extreme Precipitation and Flooding Social Value Created: recreation; public gathering space; social cohesion; connectivity; employment; benefits vulnerable communities
The City of Seattle recently redeveloped undertook a nine-acre redevelopment project to repurpose an underutilized parking lot and the surrounding area. The Thornton Creek restoration is one component of the restoration project. Thornton Creek was previously been forced below the surface as the urban area developed.
The restoration project aimed to restore the creek to manage stormwater runoff from 680 acres. Impervious surfaces were also reduced by 78%, improving ground water infiltration and thereby reducing runoff. Native species were used for 85% of the project’s landscaping, reducing water consumption for landscaping and reducing maintenance needs. The project design also improves stormwater filtration to remove pollutants from stormwater runoff, removing 40-80% of total suspended solids from 91% of runoff in the 680 acre drainage basin.
Thornton Place is a combined residential and commercial space created in the redevelopment. The project added 530 units of mixed-income housing and 50,000 square feet of retail space, including 143 units of assisted-living housing for seniors. Thornton Place also includes a 14-screen cinema and a plaza area for public gatherings. Additionally, pedestrian links were created to link adjacent commercial and residential neighborhoods, improving walkability. Transit access was also improve by the design, increasing mobility and diversity of transportation.
City: Seattle Country / US State / US Territory: Washington Type of Solution: Bridge Climate Impact: Hurricanes and Extreme Storms Social Value Created: Diverse Transportation; Public Health and Safety; Active Living and Recreation
The Washington State Department of Transportation (WSDOT) is completed reconstruction of the Evergreen Point (SR 250) floating bridge spanning Lake Washington in April 2016. The bridge is the longest floating bridge in the world. Floating bridges are support by large, water-right concrete pontoons. The bridge was reconstructed to withstand that anticipated increase in wind loads from more frequent extreme storms and hurricanes. Stronger winds may result in bridge failure by breaking the drawspan, anchor cables, or pontoons.
The new bridge design has also addressed anticipated increases in traffic congestion by increasing the width of the lands and adding a transit/High Occupancy Vehicle (HOV) lane. Additionally, there will be a new 14-foot-wide bicycle and pedestrian path that connects to recreational trails, improving recreation and increasing diversity of transportation options for commuters. The new design include flexibility for the City to add on a light rail in the future, also supporting diverse transportation options.
