Reservoirs without Condition Assurance - Permitted Development

Development near reservoirs without demonstrated condition assurance is only permitted in specific circumstances: replacement/change of use of existing buildings with no material increase in flood risk, minor development with negligible flood risk effect, or where a Flood Risk Assessment demonstrates downstream flood risk would not preclude development.

In cases where assurance on the condition, management and maintenance regime of the relevant reservoir cannot be demonstrated the development will only be permitted in the following circumstances: (a) The replacement or change of use of an existing building(s) provided it is demonstrated that there is no material increase in reservoir flood risk to the development or elsewhere; or (b) The development proposal constitutes minor development that is likely to have a negligible effect on reservoir flood risk. For the purposes of this policy, minor development has the same meaning as that provided under policy DM 46; or (c) Where the Council is satisfied, in consultation with DfI Rivers, that it has been demonstrated through a Flood Risk Assessment (FRA), or other analysis, that the downstream flood risk in the event of an uncontrolled release due to reservoir failure would not preclude the development proceeding.
