Some of the recommendations of a report into last year's flooding in the north west could take two years to implement, the Department for Infrastructure (DfI) has said.
Hundreds of homes and businesses were flooded when record rain fell across counties Londonderry, Tyrone and Donegal on August 22.
More than 100 people had to be rescued as storms ripped through the region.
The DfI report, published on Tuesday makes a total of 14 recommendations.
DFI head of development Jonathan McKee told BBC Radio Foyle: "We would consider that all of the recommendations would be complete within two years but some much sooner than that. Some of the recommendations are quite complex.
"It is in our interests that these recommendations are put in place soon because it is our desire to be able to respond more effectively and to help the public where we can.
The report looked at how government agencies, the emergency services and the Derry City and Strabane council responded in the aftermath of the floods.
It notes the absence of a multi agency coordination centre during the floods and states the yellow weather warning failed to indicate the scale of the event.
It also recommends improving the effectiveness of the flooding incident helpline and has put the final repair bill at more than £12million.
The report further recommends the development of an online mapping tool to report and display emergency flood calls, the establishment of community response teams in flood risk areas and improved information sharing and coordination between agencies.
The department is holding a public information and engagement event is to be held on Thursday at Londonderry's Everglades Hotel.
