Strategic Flood Risk Assessment: Aylesbury Town Level 2 Preliminary draft

The level 1 district-wide  strategic flood risk assessment (SFRA) identified the need for a level 2 assessment to guide development at Aylesbury. The level 2 study was commissioned to compare the flood risks of the 3 alternative directions of growth for the town, to define the functional floodplain, and to guide the detailed design of surface water and flood risk attenuation measures for development. A preliminary draft was published in February 2009, with the final version published in April 2009.

A similar level 2 assessment may be required to guide development outside Aylesbury. If needed, this will be completed to inform the future allocated sites development plan document.

The preliminary reports can be downloaded free of charge by following the links below. Please follow the link on the left to view or download the final version of the report. Alternatively, you can buy a hard copy, or view a copy at our Customer Services Centre, 66 High Street, Aylesbury HP20 1SD
