Economic development in flood plains
Development of regional or sub-regional economic importance may be permitted in flood plains, requiring justification of the location choice and evidence of a thorough search for alternative sites outside the flood plain.
While most economic development is best located outside of flood plains, it is accepted that certain projects because of their nature, size or site specific requirements, may require a site that happens to fall within a flood plain. In such circumstances the policy allows for development that is demonstrated to be of significant regional or sub- regional economic importance. Normally, such a proposal will be expected to demonstrate its particular contribution to the regional economy. However, a proposal may also be considered acceptable if it is of significant sub-regional economic importance, for example, in providing employment for a substantial number of people living in one or more district council areas. In regard to such proposals, developers must justify the need for a location within the flood plain. As part of this process, there will be a requirement to demonstrate that a thorough search for sites outside the flood plain has been undertaken and to justify why these are considered unsuitable.
