Washington, D.C.: Overview

Download all of Washington, D.C. as PDF Print

Everything in the main manual and the skill guides applies in Washington, D.C. exactly as written. What’s different here is the specific hazard profile and the district’s unusual legal status, a federal district with no state legislature, its own emergency management agency, and gun and water law shaped by that status rather than by a typical state code. This page is the starting point; the other three pages under D.C. go deeper on laws, local resources, and the data behind the risks named here.

The August 2011 Virginia earthquake: damage nobody expected in a city that isn’t supposed to have earthquakes

A magnitude 5.8 earthquake centered near Mineral, Virginia, roughly 83 miles southwest of the district, shook Washington on August 23, 2011. D.C. isn’t considered an earthquake-prone city, and that’s exactly what made the damage instructive: the Washington Monument sustained more than 150 cracks, some deep enough to let daylight through, and closed for 32 months before reopening in May 2014 after a $15 million repair, split between $7.5 million in federal funds and a matching $7.5 million donation. The Washington National Cathedral came off worse: three of its four central-tower corner spires were severely damaged, along with cracked flying buttresses and destroyed masonry, at an estimated $34 million in damage that ordinary insurance didn’t cover, since it doesn’t cover earthquake damage. Restoration has run in phases since, funded entirely by private donations, with the Cathedral’s own projection putting full completion around 2029, eighteen years after the quake. See the Risks page for the full data.

The June 2012 derecho: one storm, a multi-day outage, and a heat wave that turned it dangerous

A line of hurricane-force straight-line winds, gusting past 87 mph in the Baltimore-Washington corridor, tore through the region on the evening of June 29, 2012, with almost no advance warning: derechos develop fast and don’t carry the days of lead time a hurricane does. Roughly 68,000 D.C. customers lost power, part of a multi-state outage that topped a million customers regionally, and utilities weren’t back to 90% restoration in the district until days later. The timing made it worse than a typical summer outage: a heat wave settled in immediately behind the storm, with D.C.’s daily high staying at or above 95°F for over a week and peaking at 105°F on July 7, air conditioning down across much of the city the entire time. See the Risks page for the full data.

What this means for how you use the rest of this manual

The manual’s Tier structure and the skill guides apply without modification. What’s different in D.C.: this manual’s Energy & Heat chapter assumes a heat wave and a power outage are separate risks that sometimes overlap; the 2012 derecho is a documented case of them arriving together with no warning, which is the harder planning case, not the easier one. And the 2011 earthquake is a reminder that this manual’s Shelter & Structural Safety guidance isn’t just for households in an obviously seismic state: D.C.’s older masonry rowhouses and monuments weren’t built to a seismic code, because nobody expected to need one, and the actual damage shows that mattered.
