It is vital to know about the risk that your property may face in order to understand how to prepare for it.
There are relatively small areas of the City which are at risk of flooding.
The City of London Strategic Flood Risk Assessment (2012) provides the most up-to-date information on the risks the City faces from tidal, surface water, sewer and groundwater flooding. You will find maps which show where the City's flood risks are in the Appendices.
Surface water flooding is one of the City's high risks. Surface water maps showing the flooding depths are at Appendix D6.
Business continuity is the capability of your organization to continue to deliver its products or services following a disruptive incident.
Robust business continuity arrangements are essential for businesses of any size - devising strategies to protect your key products, services and critical activities will enable you to trade through a disruption and recover promptly afterwards. The City of London's Contingency Planning Unit can support you in developing and exercising your business continuity arrangements.
There is no charge for these services for organisations based within the City of London.
