Flood Plain Mapping

If you have been advised that your site falls within a flood risk area, we can provide levels based on Ordnance Survey datum derived from GPS satellite measurement to satisfy the Environment Agency and local authority requirements.

This is essential, as the Ordnance Survey no longer completely maintains or updates its historical benchmark system. Values from mapping cannot therefore be guaranteed to be current due to settlement.

We can also supply mapping and cross sections of flood defences in support of your flood risk assessment.
