After Hurricane Harvey hit Texas, Leah Halbina reached out to friends in the Houston area to see how she could help. When she found out about Sketch City, an open, nonprofit community of technology advocates and civic hackers that used technology to organize rescue efforts, help victims locate their nearest shelter and satisfy other pressing needs, she jumped in to help. Shortly after, Leah had to use the same technology in her home state of Florida as Hurricane Irma approached and made landfall.
