Flood Risk

Flood Risk Services

GTA Civils & Transport specialises in the preparation of Flood Risk Assessments (FRA) and other associated documents, including Hydrology Reports and Flood Risk Management Plans (also referred to as Flood Warning and Evacuation Plans).

We have an outstanding track record: since January 2010 we have issued over 1220 FRA reports, with a success rate of over 95%.

GTA Civils & Transport has been successful in obtaining approval for particularly difficult projects, including those lying within areas prone to coastal or river flooding. Surface Water flooding is now treated by many flood authorities as strictly as river/coastal flooding – and we have had many successes with these challenges.

We are happy to provide advice on the proposed levels and positioning of buildings in order to maximise the chances of success for our clients, both in relation to Local Planning Authority or Environment Agency approvals and to ensure the long term health and safety of sites’ occupants.

Our appointments have been many and varied, including projects comprising dwellings, commercial, retail, education, public assembly and worship, industrial and agricultural components. We have helped clients obtain planning permission for new builds, extensions, change of use and divisions (where a single dwelling is split into two or more flats – or HMOs).

We also prepare FRA reports for Prior Approval applications for change of use from agricultural and offices to residential dwellings.
