ESI’s flood risk consultants offer technical support and advice throughout
the flood risk assessment process. Having supported many planning
applications ESI has built an excellent relationship with the various
Environment Agency regional offices and with local authority planning
officers.
Local planning authorities are likely to request a flood risk assessment for
any site which is situated on the modelled flood plain and within the vicinity
of a fluvial or tidal watercourse. Flood risk assessments are also requested
in areas of low fluvial or tidal flood risk if a proposed development is over
one hectare in size and/or lies within a critical drainage area. Certain areas
are also susceptible to groundwater flooding; under such conditions, ESI
can provide impact assessments for basement construction.
Dedicated points of contact: “I was very pleased with the work that ESI undertook for us. We were in
a position where our house sale had fallen through based on misleading
Dr Paul Ellis survey data. ESI understood our problem straight away and quickly turned
Technical Director around a very detailed report that satisfied our buyer. As a result the sale is
paulellis@esinternational.com now progressing. I found the report to be very comprehensive. It covered
the technical and geological data, but was also written in a way that was
Rosanna Fildes easy to understand. ”
