5ft Flood Projection
This map shows exactly what areas in Savannah that would be affected by a single flood that is 5 feet higher than the longer high-tide line. It is also the new projected shoreline if sea-levels were to rise 5 feet higher than they are now. A 5-foot flood is projected to happen at least once by the year 2080.
Due to Savannah’s low elevation and close proximity to the ocean, chronic flooding and rising water levels are a relevant environmental vulnerability (Surging Seas, 2016). Storm surges cause intense, sudden flooding when strong storms from the ocean make landfall on the cost. These storm surges are projected to only get worse as global warming raises sea levels and produces stronger storms every year. This map, taken from elevation and water-level data available from the National Oceanic and Atmospheric Association (NOAA), shows the areas in and around Savannah that experience flooding in the event of a flood 5 feet above the local normal high tide. According to experts, there is a 23% likelihood of such a flood occurring between now and 2060, and is 100% likely by 2080 (Surging Seas, 2016). This map can be cross-examined with spatial analysis of various social and economic issues to determine which demographics of Savannah would be most impacted by potential sea level rise-induced flooding.

Tree Canopy
The City of Savannah is known for its large trees and iconic Spanish moss. This foliage also helps cool down the city, especially in Savannah’s 22 Historic Squares. This map shows the density of tree coverage in the City of Savannah and the surrounding areas.
A city’s tree canopy has a strong effect on the local ground temperature and air quality, so plotting this for the city of Savannah was crucial in understanding the full environmental scope of the present green infrastructure of the region. This map, available through the U.S. Forest Service as part of the National Land Cover Database 2016 (NLCD2016), was developed using satellite imaging and medium spatial resolution (1 pixel = 30m). Each pixel is weighted by percent tree canopy cover on a scale of 0 to 100 percent (U.S. Forest Service, 2019).

Urban Heat Island Effect
This map shows the ground temperature of the areas around the City of Savannah. Notice the higher heat levels in the more developed regions, demonstrating the idea that cities are generally hotter than their surroundings.
A heat island occurs when the built infrastrastructure in a city traps heat near the ground level, causing higher temperatures than nearby rural areas. The heat island effect causes an increase in energy consumption and air pollutants and it also affects human health. This map shows the urban heat island effect in Savannah and indicates areas in the city where the effect is most severe. Severity is rated from 1 to 5, where 1 is a relatively mild heat area (slightly above the mean for the city) and 5 is a more severe heat area (significantly above the mean for the city). The map was sourced from the Trust for Public Land and shows the urban heat island effect for every major metropolitan area in the United States. The data was originally obtained from Landsat 8 imagery with thermal band 10, which is a ground-level thermal sensor, from the summers of 2018 and 2019. Using Python and the Descartes Lab platform the Trust was able to create these urban heat island effect maps (The Trust for Public Land, 2020).

Groundwater Pollution
The city of Savannah sources its water from either the Savannah River or the Floridan aquifer, which is an underground layer that contains water. In the map above, we show which areas of the city are more likely to be affected by pollution trickling down into this underground layer.
Savannah sources most of its water from two different sources: the Savannah River and the Floridan Aquifer. However, these two different water sources face issues such as pollution as a result of chemical waste and aquifer depletion (Groundwater Pollution, 2020). The map, sourced from the Savannah Area GIS Open Data, helps provide a rating for which areas of the city are more susceptible to groundwater pollution. The map above uses a DRASTIC-index to measure groundwater vulnerability. This index measures seven different parameters: depth to water, net recharge, aquifer media, soil media, topography, vadose zone and hydraulic conductivity (Trent 1992). The first parameter measures the depth from the ground surface to the water table. The net recharge measures the total amount of rain water that infiltrates to reach the shallow unconfined aquifer. The aquifer media analyzes which earth materials from the aquifer. The soil media pertains to the upper portion of the vadose zone that consists of significant biological activity. Topography looks at the slope and slope variability in that parcel of land. The vadose zone refers to the area above the water table which is unsaturated or discontinuously saturated and finally, the hydraulic conductivity determines the ability of a material to transmit water (Trent 1992).

CO2 Factory Emissions
This map shows the locations of factories in the Savannah area that produce the most pollutants. Most of these factories lie along the river, which pollute the river along with the air. The larger the grey circle representing the factory, the more pollutants that factory produces.
To better understand the air quality of Savannah, we plotted nine factories with substantial greenhouse gas emissions using data from 2018 from the EPA’s FLIGHT tool. All emissions data is presented in units of metric tons of carbon dioxide equivalent using GWP's (Global Warming Potentials) from IPCC's AR4 (EPA, 2018). Greenhouse gas emissions are known to cause climate change by trapping heat, along with the potential to cause respiratory diseases due to increased air pollution. With this information, a rough extrapolation can be made about what areas of the city of more polluted air and overall lower air quality.

Sea Level Rise Sensors
The map above shows the location of different sea level sensors installed through Dr. Kim Cobb’s research. These sea level sensors continuously collect and report data on water level, air temperature, and air pressure.
Flooding can occur rapidly without much warning. Properly warning residents of incoming floods requires real-time monitoring of environmental characteristics like air temperature, water levels, and atmospheric pressure. In collaboration with Dr. Kim Cobb, we have created a map detailing the locations of each of her Smart Sea Level Sensors around the Savannah area. Each sensor measures different metrics based on their capabilities (i.e. one sensor measures air temperature and water level while another measures water level barometric pressure). Clicking on a sensor on our map leads to a link detailing that device’s real time data, along with any past data the sensor may have collected. This map was created by plotting the latitude and longitude of each sensor as points on our map, and attaching links to each point corresponding to the appropriate sensor (Cobb, 2020).

Energy Burden by Census Track
This map shows the energy burden by census track in Bryan, Chatham, and Effingham counties (Greenlink, 2020). The energy burden is calculated by the amount of electricity and gas consumed compared to the household median income.
Household energy burden is defined as a large portion of the house income that is spent in home energy bills, including electricity, gas, and other heating fuels (US Department of Energy, 2018).
Low-income households suffer a disproportionate energy burden - the national average energy burden for low-income households is 0.086 (8,6%), which is three (3) times higher than for non-low-income households (US Department of Energy, n.d.).
Low-income Georgians face high energy burden despite having some of the lowest energy rates in the United States (ACEE, n.d.).

Poverty by Zip Code
This map showcases poverty rates in Chatham County, organized by ZIP code boundaries. Poverty rate is a rather direct measure of the economic vitality, or vulnerability, of an area which in hand allows us to approximate which areas are and will be more prepared to combat the effects and future costs of climate change.
The poverty variable shows the percentage of the population that’s at or above the poverty line in Savannah. Areas on the map with higher poverty rates indicate areas with an increased inability to combat climate change. The lighter colors closer to cream signify poverty rates at or below 4%. The closer to a darker brown that the map gets signifies poverty rates at or above 26%.

Increased Need for Flooding Insurance
This map showcases the zones where Flood Insurance Needs decreased or increased.
Flood insurance protects owners from property loss due to flooding. The most recurrent problems for Savannah in recent years are minor flash floods caused by surface water runoff in locations of low elevation, particularly where storm drains are blocked by debris (City of Savannah, 2015). This layer was produced by the Chatham County government in collaboration with FEMA. It shows the likelihood of flooding in a given year from storm surges and outlines where there is a need for flood insurance. Properties falling within the red-lined boundary have an increase in need for flood insurance, while properties falling within the blue-lined boundary have a lessened need for flood insurance.

Unemployment Rate.png
This map shows the unemployment rate by area within Chatham County. Unemployment rate is being used as a proxy for the economic vulnerability of an area.
The unemployment rate variable represents the percent of Chatham County residents that are jobless despite them actively seeking work. This gives us an indication of the economic vulnerability of an area. Lighter colors represent lower unemployment rates which exhibit a stronger economic base within the area, while darker colors exhibit higher unemployment rates which convey an underlying economic vulnerability for that area. As costs of living rise due to climate change going into the future, economically vulnerable areas will be less able to compensate.

This map shows the total electricity consumption (residential, commercial, and industrial) by zip codes normalized by percentage of the population living in the City of Savannah in kWh for the year 2019.
Georgia Power, the local utility in Savannah, provided a consolidated data of electricity consumption in the residential, commercial, and industrial sectors by zip code (N. Deffley, personal communication, July 7, 2020). In order to determine the percentage of this electricity consumed exclusively within the City of Savanna limits, we used the percentage of the area of Savannah within those respective zip codes as a proxy (City-Data, 2020)

Energy Burden by Census Track
This map shows the energy burden by census track in Bryan, Chatham, and Effingham counties (Greenlink, 2020). The energy burden is calculated by the amount of electricity and gas consumed compared to the household median income.
Household energy burden is defined as a large portion of the house income that is spent in home energy bills, including electricity, gas, and other heating fuels (US Department of Energy, 2018).
Low-income households suffer a disproportionate energy burden - the national average energy burden for low-income households is 0.086 (8,6%), which is three (3) times higher than for non-low-income households (US Department of Energy, n.d.).
Low-income Georgians face high energy burden despite having some of the lowest energy rates in the United States (ACEE, n.d.).

Poverty by Zip Code
This map showcases poverty rates in Chatham County, organized by ZIP code boundaries. Poverty rate is a rather direct measure of the economic vitality, or vulnerability, of an area which in hand allows us to approximate which areas are and will be more prepared to combat the effects and future costs of climate change.
The poverty variable shows the percentage of the population that’s at or above the poverty line in Savannah. Areas on the map with higher poverty rates indicate areas with an increased inability to combat climate change. The lighter colors closer to cream signify poverty rates at or below 4%. The closer to a darker brown that the map gets signifies poverty rates at or above 26%.

All Businesses by Major Category
This map showcases all businesses registered with the Savannah Area Chamber of Commerce, color coded by category.
The Savannah Area Chamber of Commerce provided our team with their member businesses information such as names, addresses and business type. The businesses were organized by type into the following categories: private businesses & resources, events, tourism & arts, civic organizations, advertising & design, cargo, and other. The ‘All Businesses by Major Category Map’ can be used to layer with other maps like the food desert map to guide developers in making sustainable urban development planning decisions. Also, the map can be used by residents and tourists to locate a type of business and get a better idea of the areas in Savannah.

Increased Need for Flooding Insurance
This map showcases the zones where Flood Insurance Needs decreased or increased.
Flood insurance protects owners from property loss due to flooding. The most recurrent problems for Savannah in recent years are minor flash floods caused by surface water runoff in locations of low elevation, particularly where storm drains are blocked by debris (City of Savannah, 2015). This layer was produced by the Chatham County government in collaboration with FEMA. It shows the likelihood of flooding in a given year from storm surges and outlines where there is a need for flood insurance. Properties falling within the red-lined boundary have an increase in need for flood insurance, while properties falling within the blue-lined boundary have a lessened need for flood insurance.

Unemployment Rate.png
This map shows the unemployment rate by area within Chatham County. Unemployment rate is being used as a proxy for the economic vulnerability of an area.
The unemployment rate variable represents the percent of Chatham County residents that are jobless despite them actively seeking work. This gives us an indication of the economic vulnerability of an area. Lighter colors represent lower unemployment rates which exhibit a stronger economic base within the area, while darker colors exhibit higher unemployment rates which convey an underlying economic vulnerability for that area. As costs of living rise due to climate change going into the future, economically vulnerable areas will be less able to compensate.

Food Deserts
This map shows low-income census tracts where a significant portion of the population has low-access to grocery stores and supermarkets. A darker red represents a higher percentage of the population with low-access to grocery stores and supermarkets.
The USDA defines food desert census tracts as: Low-income census tracts where a significant number (at least 500 people) or share (at least 33 percent) of the population is greater than 1.0 mile from the nearest supermarket, supercenter, or large grocery store for an urban area or greater than 10 miles for a rural area. Low income census tracts are any tract where: The tract’s poverty rate is 20 percent or greater; or the tract’s median family income is less than or equal to 80 percent of the State-wide median family income; or the tract is in a metropolitan area and has a median family income less than or equal to 80 percent of the metropolitan area's median family income. It is important to note that a food desert by USDA definition is low access and low income (USDA, 2015).
Access to affordable, healthy foods is an important indicator of a community’s health and well-being. By mapping this data, we can see which areas of Savannah need assistance in accessing nutritious food, either by increasing accessibility to grocery stores, or by offering more affordable options.

SNAP
This map shows the percentage of households receiving Supplemental Nutrition Assistance Program (SNAP) benefits in each census tract. A darker purple color represents an area with a higher percentage of households receiving SNAP benefits.
The Supplemental Nutrition Assistance Program (SNAP, formerly the Food Stamp Program) is the Nation's largest domestic food and nutrition assistance program for low-income Americans. This data comes from the United States Department of Agriculture. As stated by the USDA, SNAP provides nutrition benefits to supplement the food budget of families so they can purchase healthy food and move towards self-sufficiency. A spatial analysis of the SNAP benefits data can provide insight into different issues surrounding food insecurity such as which communities may typically be less food secure.

Crime by Precinct
This map shows the concentration of crime in the 4 police precinct zones in Savannah, GA. A darker red represents an area with a higher crime rate.
The city of Savannah consists of four police precincts: Northwest, Southside, Central, and Eastside. The map shows the amount of crime, which is defined as all gun crimes, drug crimes, and felony crimes, in each of the precinct’s respective zones from January of 2020 to June of 2020. In the map, the central precinct is clearly the zone with the highest concentration of crime (Savannah Police, 2020). This data was received from the city of Savannah’s police department weekly crime report. Crime is an indicator of poverty and correlates with residents’ health, safety, and well-being. Additionally, how the police respond and react to crime, especially in relationship to the race of the resident, is an extremely relevant and urgent equity issue that must be addressed in Savannah, and in the rest of the United States.

Percent of African Americans
This map shows the percentage of Black residents of each census tract in Chatham County. A darker blue represents an area with a higher concentration of Black residents.
This information comes from the Atlanta Regional Commission Open Data. Black individuals in the United States continue to be neglected and suppressed by the government which can be seen in how they are disproportionately affected by the changing climate. By seeing where Black citizens reside in Savannah, we can see which vulnerabilities are concentrated in Black communities to give a better understanding if/why they need more help than others in order to obtain an equitable society.

Housing Burden
This map shows the percentage of households in each census tract that are burdened with housing problems. A darker purple represents an area with a higher percentage of burdened households.
what is shown is the percentage of households in each census tract with at least one of four housing problems. There are four housing problems in the CHAS data: 1) housing unit lacks complete kitchen facilities; 2) housing unit lacks complete plumbing facilities; 3) household is overcrowded; and 4) household is cost burdened. When it comes to the climate crisis, those with poor living conditions or those with no place to live are arguably the most vulnerable to a changing climate.Because of this, we must identify where these groups are concentrated and find solutions to mitigate the burden. This map was developed from the US Department of Housing and Urban Development Data along with the help of Mosaic Community Planning.

The map shows the amount of crime, which is defined as all gun crimes, drug crimes, and felony crimes, in each of the precinct’s respective zones from January of 2020 to June of 2020. In the map, the central precinct is clearly the zone with the highest concentration of crime (Savannah Police, 2020). This data was received from the city of Savannah’s police department weekly crime report. Crime is an indicator of poverty and correlates with residents’ health, safety, and well-being. Additionally, how the police respond and react to crime, especially in relationship to the race of the resident, is an extremely relevant and urgent equity issue that must be addressed in Savannah, and in the rest of the United States.

Percent of African Americans
This map shows the percentage of Black residents of each census tract in Chatham County. A darker blue represents an area with a higher concentration of Black residents.
This information comes from the Atlanta Regional Commission Open Data. Black individuals in the United States continue to be neglected and suppressed by the government which can be seen in how they are disproportionately affected by the changing climate. By seeing where Black citizens reside in Savannah, we can see which vulnerabilities are concentrated in Black communities to give a better understanding if/why they need more help than others in order to obtain an equitable society.

Housing Burden
This map shows the percentage of households in each census tract that are burdened with housing problems. A darker purple represents an area with a higher percentage of burdened households.
what is shown is the percentage of households in each census tract with at least one of four housing problems. There are four housing problems in the CHAS data: 1) housing unit lacks complete kitchen facilities; 2) housing unit lacks complete plumbing facilities; 3) household is overcrowded; and 4) household is cost burdened. When it comes to the climate crisis, those with poor living conditions or those with no place to live are arguably the most vulnerable to a changing climate.Because of this, we must identify where these groups are concentrated and find solutions to mitigate the burden. This map was developed from the US Department of Housing and Urban Development Data along with the help of Mosaic Community Planning.

Food Deserts
This map shows low-income census tracts where a significant portion of the population has low-access to grocery stores and supermarkets. A darker red represents a higher percentage of the population with low-access to grocery stores and supermarkets.
The USDA defines food desert census tracts as: Low-income census tracts where a significant number (at least 500 people) or share (at least 33 percent) of the population is greater than 1.0 mile from the nearest supermarket, supercenter, or large grocery store for an urban area or greater than 10 miles for a rural area. Low income census tracts are any tract where: The tract’s poverty rate is 20 percent or greater; or the tract’s median family income is less than or equal to 80 percent of the State-wide median family income; or the tract is in a metropolitan area and has a median family income less than or equal to 80 percent of the metropolitan area's median family income. It is important to note that a food desert by USDA definition is low access and low income (USDA, 2015).
Access to affordable, healthy foods is an important indicator of a community’s health and well-being. By mapping this data, we can see which areas of Savannah need assistance in accessing nutritious food, either by increasing accessibility to grocery stores, or by offering more affordable options.

SNAP
This map shows the percentage of households receiving Supplemental Nutrition Assistance Program (SNAP) benefits in each census tract. A darker purple color represents an area with a higher percentage of households receiving SNAP benefits.
The Supplemental Nutrition Assistance Program (SNAP, formerly the Food Stamp Program) is the Nation's largest domestic food and nutrition assistance program for low-income Americans. This data comes from the United States Department of Agriculture. As stated by the USDA, SNAP provides nutrition benefits to supplement the food budget of families so they can purchase healthy food and move towards self-sufficiency. A spatial analysis of the SNAP benefits data can provide insight into different issues surrounding food insecurity such as which communities may typically be less food secure.
