Risk Factor™ is a free online tool created by the nonprofit First Street Foundation® that makes it easy for Americans to find their property’s risk from environmental threats such as flooding and wildfires and understand how risks are changing because of a changing environment.

First Street Foundation’s mission is to address the asymmetry in access to high-quality climate change data by quantifying and communicating America’s environmental risks so that everyone can make informed decisions for the future. By making flood and fire risk data accessible and easy to understand, individuals and communities can prepare for and mitigate risks before they become a reality.

Look up your zipcode to get an assessment of environmental disaster risk in your area.

Wikihouse is an archive of open source building designs contributed by engineers and architects around the world. Each design is peer-reviewed and analyzed by others to ensure that the designs are sound. Some of them have already been built and the results posted for further review. The design principles include being as easy to build by people with minimal formal training, as energy efficient as possible, and easy to modify to fit a particular purpose. All designs are made in Google Sketchup and can be cut with an automill if available.
