Data Center: 10 Places You Don’t Want to Build

If you agree, or disagree with the order of our list, or would like to suggest additional location criteria, cast your vote/send your input.

1. Below sea level or in a floodplain
The National Flood Insurance Program (NFIP), created by the U.S. Congress in 1968 created Flood Insurance Rate Maps (FIRM). FIRMS show floodplains in the same way topographic maps show terrain. A 10-year floodplain can be expected to meet or exceed a given flood level every 10 years, a 100-year floodplain every 100 years, etc. FIRMs are accessible on the FEMA web site (address below). Input State, then County, then Community (cities or areas) and available maps are presented for review.

Moderate to Low Risk Areas (ideal for data centers)
B and X: between 100 and 500-year floodplains
C and X: above the 500-year flood zone (best)

High Risk (poor data center locations)
A: 1% chance of flooding in a given year with a 26% chance of flooding over 30 years
V: Coastal area with similar probabilities to “A”

2. In a location that suffers from frequent natural disasters
Between 1955 and 2004, Florida averaged 55 tornadoes (F3-F5) annually, according to NCDC (National Climactic Data Center). Texas averages 139 annually. By comparison, Virginia averages 10. Between 1851 and 2004, Texas experienced direct hits from 19 major (F3-F5) hurricanes (approximately 21% of total U.S. hits), according to NOAA memorandum NWS TPC-4. Florida experienced 35 major hurricane hits (approximately 38% of total U.S. hits). Virginia experienced a single F3 hurricane hit between 1851 and 2004.

Locations at highest risk for dangerous weather and are not ideally suited for data centers.
