Monitoring Report 8: Flood Management and Mitigation

This report is one of a series of topic based reports which together constitute the Christchurch and East Dorset Authorities' Monitoring Report.

These reports will be regularly updated. The date that the information was last updated is indicated alongside each table/section as appropriate. Further topic areas can be viewed in the Christchurch and East Dorset Authorities' Monitoring Report.

Flood risk

For the period 2015-2018, no planning permissions were approved in East Dorset or Christchurch that were contrary to Environment Agency advice on flooding.

National planning policies and local plan policies (Core Strategy Policy ME6) seek to steer development away from areas of flood risk (zones 2 and 3a) by applying the sequential test. The sequential test does not allow development in areas of flood risk if there are reasonably available sites in areas with a lower probability of flooding.

The tables below show permissions that have been granted in the monitoring years 2015-2018 for new additional dwellings in flood zones 2 and 3a. It should be noted that this excludes applications where part of the site boundary falls within the zones but where the footprint of the building is outside the zone; and it excludes replacement dwellings. As illustrated all these permissions were for changes of use which the national policy exempts from the sequential test. Therefore they were considered to accord with national and local planning policies for flood risk.

Permissions granted (1 April 2015 - 31 March 2016) for additional new dwellings in flood zones 2 and 3a (Christchurch and East Dorset)

These applications were all for changes of use. As such the sequential test for flood risk does not apply (para 104 of the National Planning Policy Framework, NPPF 2012), so the proposals did not conflict with national and local plan policies with regard to flood risk.

The new dwelling is located wholly outside the flood zone areas and is therefore not subject to the sequential and exception tests as set out in the Core Strategy and LPPF guidelines.

The extant planning consent for two dwelling houses on the site (following demolition of the existing bungalow -

ref: 8/08/0019) did not include any flood alleviation measures, it is considered that the current proposed development provides the opportunity to incorporate measures which would represent a betterment to the existing approval.

8/16/2157FUL

External alterations to the building, construction of a 3rd storey for accommodation to provide six apartments plus associated landscaping works.

30/12/2016

The change of use from offices to residential use was "Permitted Development" (prior approval decision 8/16/0074) so it was not subject to the sequential test.

This subsequent application for an additional storey (8/16/2157) was approved 30/12/16.
