More than 800 flood claims have been filed in New Orleans, though that number might not represent all the damage from the Aug. 5 flood that was caused by an extreme rain event and failures with the city’s pumping system. The number, released by the city Monday night, was calculated through FEMA’s National Flood Insurance Program. Because the flooding was so different from block to block, the city is going door-to-door in impacted areas to try to assess the damage. The city is seeking volunteers to help with going door-to-door and also asks that anyone with questions on debris collection, flood assessment or flood cleanup call 311 as this helps the city get more information about specific impact of flooding.
