§ Andy BurnhamTo ask the Deputy Prime Minister what steps he is taking to address problems with flooding in areas of new housing development. [72362]
§ Mr. McNultyIn July 2001 the Government published Planning policy guidance note (PPG) 25Development and flood risk. This introduces a risk-based approach to planning for new development that gives priority to lower risk areas. Within high-risk areas priority is given to those areas that are already developed. Built development should be wholly exceptional within the functional flood plains that are essentially unobstructed by defences and existing development.
Those proposing new development are advised to carry out a flood-risk assessment. This should assess the risks of flooding to the development, its impact on flooding elsewhere (including the impact of increased 946W run-off due to development) and identify any mitigation measures that may be required. Where flood defences or other mitigation is required because of a new development, its provision and future maintenance should be fully funded by the developer as part of the development.
In February 2002, DTLR published Preparing for floods. This contains interim guidance for improving the flood resistance of domestic and small business properties. It provides practical advice for existing property owners whose properties are at risk of flooding and for all those involved with construction of new properties or renovation of existing buildings in areas of flood risk. The Environment Agency, together with the Construction Industry Research and Information Association, has also produced guidance on temporary measures to protect against flooding (such as flood boards) and on what to do after a flood.
