DM 18.1 Development in the City Flood Risk Area

  1. Where development is proposed within the City Flood Risk Area evidence must be presented to demonstrate that:
    • the site is suitable for the intended use (see table 18.1), in accordance with Environment Agency and Lead Local Flood Authority advice;
    • the benefits of the development outweigh the flood risk to future occupants;
    • the development will be safe for occupants and visitors and will not compromise the safety of other premises or increase the risk of flooding elsewhere.
  2. Development proposals, including change of use, must be accompanied by a site-specific flood risk assessment for:
    • all sites within the City Flood Risk Area as shown on the Policies Map; and
    • all major development elsewhere in the City.
  3. Site-specific flood risk assessments must address the risk of flooding from all sources and take account of the City of London Strategic Flood Risk Assessment. Necessary mitigation measures must be designed into and integrated with the development and may be required to provide protection from flooding for properties beyond the site boundaries, where feasible and viable.
  4. Where development is within the City Flood Risk Area, the most vulnerable uses must be located in those parts of the development which are at least risk. Safe access and egress routes must be identified.
  5. For minor development outside the City Flood Risk Area, an appropriate flood risk statement may be included in the Design and Access Statement.
  6. Flood resistant and resilient designs which reduce the impact of flooding and enable efficient recovery and business continuity will be encouraged.
