Among the 15 measures in the draft strategic flood risk assessment is a proposal to vary density levels to create green space to soak up rain and flood water.
The idea emerged after major flooding affected 8,120 homes in the city this summer (Planning, 20 July, p5). The council wants to amend the city centre action plan and leave undeveloped land in the highest areas of flood risk to store water.
The city will be divided into six different risk zones and all new development will need flood-proofing. Permitted development rights for householders will be removed in major risk areas.
Committee chairman John Fareham said the recommendations will give flood risk a high priority and offer certainty to developers. The final document will go back to committee next month.
