A Disaster Recovery Center is open in Marshalltown beginning today to give survivors from the Aug. 10 derecho storm options to submit documents for their disaster assistance application. The center will offer drive-thru service, and survivors are asked to stay in their vehicles when visiting. Applicants do not have to visit a center to submit documents to FEMA, and can mail, fax or submit them online at disasterassistance.gov. Those who have received a letter from FEMA and have questions can call 800-621-3362 between 6 a.m. and 10 p.m.
