Many San Francisco tech companies are located in waterfront areas that are particularly vulnerable to sea level rise.
Companies like Square and Twitter appear to be safe, while the LinkedIn office is just shy of the predicted flood plain.
Google's San Francisco office runs up against the San Francisco Bay, making it one of the most likely tech companies to experience flooding.
Though floods aren't expected to reach the tops of buildings, they pose a severe threat to electrical grids and sewage pipelines.
Waterfront attractions at the Embarcadero, a popular area among tourists and locals, await a similar fate.
The city's historic Ferry Building, which has been around since the end of the 19th century, could soon be underwater.
Pier 39 receives around 11 million annual visitors, while Fisherman's Wharf sees about 12 million per year.
The Transamerica Pyramid, once the tallest tower in San Francisco, could experience flooding by 2100.
The city's controversial Millennium Tower is included in the flood plain, along with the Salesforce Tower, which is still under construction in this Google Earth photo.
The Millennium Tower already faces structural issues. The tower has sunk 17 inches and tilted 14 inches in the last decade.
By far one of the most devastating consequences of extreme flooding would be damage to the San Francisco International Airport.
The airport serves nearly 56 million passengers a year and employs around 43,000 people. If the area were to be hit by floods, it could have severe economic consequences both inside and outside the Bay Area.
