Policy FLD 5: Development in Proximity to Reservoirs
New development in potential flood inundation areas of controlled reservoirs requires demonstration of reservoir safety assurance and submission of a Flood Risk Assessment covering controlled/uncontrolled water release scenarios and mitigation measures.
New development will only be permitted within the potential flood inundation area of a "controlled reservoir" as shown on the Strategic Flood Map, if:
• the applicant can demonstrate that the condition, management and maintenance regime of the reservoir is appropriate to provide sufficient assurance regarding reservoir safety, so as to enable the development to proceed;
• the application is accompanied by a Flood Risk Assessment which demonstrates:
1. an assessment of the downstream flood risk in the event of:
- a controlled release of water
- an uncontrolled release of water due to reservoir failure
- a change in flow paths as a result of the proposed development
and
2. that there are suitable measures to manage and mitigate the identified flood risk, including details of emergency evacuation procedures
