A Sunshine Coast Regional Council report has found severe flooding earlier this year was exacerbated by blockages in creeks and waterways, particularly on state land.
The council report to today's ordinary meeting will outline how 74 homes were flooded and 22 deemed uninhabitable during severe flooding in February and March this year.
Communities from Pomona to Buddina were affected.
The report found the extreme rainfall events were well above the required design level for roads, drains and buildings.
Some homes and businesses went under, despite being above one-in-100-year flood levels.
It also found council crews and other emergency services were stretched beyond capacity.
In some areas the need for improved drainage in creeks and waterways and removal of silt and vegetation on state land is highlighted.
Council is working with government agencies to improve maintenance in high risk areas.
A flood review panel has been established to investigate the worst affected areas and any improvements needed.
