Arlington's preliminary estimate is that Hurricane Sandy caused at least $1.17 million in damage in the county.

The amount, which is expected to increase, includes damage to county property, overtime for staff during the storm and recovery, equipment and supplies. 

“We’re still early in this process,” Jack Brown, director of the county’s Office of Emergency Management, said in a statement. “That estimate will go up, not down.”

Arlington County ended its declaration of a local emergency Thursday just before noon — about four days after County Manager Barbara Donnellan declared it, according to a news release.

Aside from public costs, county officials know of at least one private home that was destroyed by the superstorm. Seventeen more suffered major damage and 27 suffered minor damage, the news release states.

Arlington's damage estimates already are well above the threshold for federal disaster relief. The county will submit its estimates to the state to be included for reimbursements through the Federal Emergency Management Agency.
