Flood Risk and Drainage

DHA Transport are experienced in providing a range of Flood Risk and Drainage services associated with all forms of development from residential to commercial. 

DHA can prepare Flood Risk Assessments (FRA) and drainage statements / strategies to help inform masterplans and accompany planning applications through to detailed design and obtaining agreement with the various statutory authorities. 

FRAs are required to accompany planning applications for development where the site area exceeds one hectare and for all developments located within Flood Zones 2 and 3. 

For major developments i.e. greater than 10 dwellings or 1,000 m2 of commerical space, planning applications need to be accommpanied by a drainage statement which demonstrates how surface water is to be dealt with.
