How Google helps people seek refuge from Colorado floods

Google Crisis Maps and other digital media are becoming the go-to resource for those in a crisis, most recently those affected by the Colorado floods. But with any natural disaster, sometimes the crisis moves faster than what can be mapped.

"A big determinant is whether we can actually make a difference," he says.

For some Coloradans, it has even become a repeat resource. Michael St. James, a music executive who lives in Denver, first used the Crisis Map to track the wildfires that burned through parts of western Colorado last year. So when a friend needed navigation help during the flooding, he knew where to go.

“In Longmont, a friend with extra rooms in his house [had] put the word out to the residents who were evacuated, but providing directions for them to find a safe place was nearly impossible,” Mr. St. James says. “With the crisis map, we were able to plot a course to get them there safely. That night he hosted four people and pets.”

St. James also points out that the Google Crisis Map includes rural areas that don't get much media attention. Plus, the map is more compatible with mobile devices. Mobile sites from newspapers and TV stations, he says, often jumble important facts with advertisements and side stories.

“What people need is actionable, updated, uncluttered information delivered immediately in a crisis,” he says.

Google isn’t the only website using tech to get the word out. FEMA has an ongoing online photo directory showing what it looks like on the ground. Weld County (north of Denver) is updating a road closure map on its website. The Jefferson County Sheriff’s Department (west of Denver) created their own Google Map that showed specific information in their county, and were tweeting updates with the hashtag #JeffCoFlood.

And people are logging on. As of Sept. 17, the Jefferson County map had more than 1 million views.

However, when a natural disaster strikes, information isn’t always updated with accuracy or speed.

Lori Jarrett, who owns her own real estate company and lives in Kersey, Colo. with her daughter, tweeted the link to the Google Crisis Map on Sept. 14 as a resource to her friends and real estate clients. Two days later, however, she said it wasn’t what she hoped.

“The map is not accurate when I look at it, though it looks like they are starting to update it a bit,” she says. She points to highways she had tried to cross that were flooded, bridges that had been washed out, and the disparity of resources marked in more populated areas, such as Boulder, as opposed to those near her small town. The map has filled in over time, but wasn't complete when Ms. Jarrett needed it. Kersey, a town of about 1,500, is located near the South Platte River, which was rising at 100 times the normal rate on Friday. Weld County, where the town is located, estimates the floods have caused more than $230 million in damage. Falor says that, in areas that are being hit hard, it can be tough to stay on top of new developments.

“It’s a tricky business," he says. "What we try to do is be sure we are referencing the most official, most accurate sources possible."

Especially at times when the situation changes hour by hour, the emergency responders that provide Google with its information may not be able to stay on top of updating their website.

“We can't be everywhere but we want to make sure we have the tools so people can map their own community," Mr. Snoad says.
