Climate Ready Boston Map Explorer
The Map Explorer features spatial data from Climate Ready Boston. Explore which areas in Boston are projected to be at risk of flooding (due to sea level rise and increased precipitation) and extreme heat (due to rising temperatures and the urban heat island effect). Overlay climate data with population demographics to better understand the social factors that intersect with and contribute to vulnerability. See the current and upcoming projects the City is working on to enhance climate resilience. And then dive deeper and download the data through the City's Analyze Boston platform.
Note: This tool is intended for educational and outreach purposes. It should not be used for technical planning.
Map ComponentsMap Components
The visibility and opacity of layers displaying data related to flooding, extreme heat, and social vulnerability can be adjusted in the “Layers” tab to compare specific datasets and create a unique look.
You can view information about each component and its source data by clicking the feature on the map. More details, source information and links to download the data are available in the “Details” tab.
In order to explore your neighborhood more in depth and get the look you desire, the “Basemap gallery” tab allows you to swap out the light grey underlying map for other street maps or satellite imagery.
About the DataAbout the Data
Details: Area of potential coastal and riverine flooding in Boston under various sea level rise scenarios (9-inch in 2030s, 21-inch in 2050s, and 36-inch in 2070s) at high tide and in the event of storms with an annual exceedance probability (AEP) of 10 and 1 percent.

Details: Approximate stormwater flooding extents from a 10-year, 24-hour rainfall event under various climate conditions, due to combined future sea level rise and extreme precipitation (5.6-inch, 5.8-inch, and 6-inch rainfall).

Note: This data should not be used for detailed analysis as it does not necessarily identify all areas subject to flooding particularly from local drainage sources of small size. Users should be aware that inundation areas are calculated by mathematical models with precision that is limited to historical calibrations.
Details: Areas designated urban heat islands with elevated daytime land surface temperatures (LST) averaging at least 1.25 degrees Fahrenheit above the mean daily temperature during late June/early July.

Details: Census tracts where the concentration vulnerable populations falls in the top quartile (25 percent) of Boston tracts. Social vulnerability is defined as the disproportionate susceptibility of some social groups to the impacts of hazards, including death, injury, loss, or disruption of livelihood. Groups identified as being more vulnerable are older adults, children, people of color, people with limited English proficiency, people with low or no incomes, people with disabilities, and people with medical illnesses.
