Our Services – Flood Risk Topographical Survey2018-10-19T10:21:17+00:00


We assist clients with their floor risk applications by providing accurate survey data and drawings to national co-ordinates in plan and height.

Supporting Your Flood Risk Assessment

It is common for flood risk assessments to require an accompanying level survey to demonstrate the contours of the site. Flood risk assessments are generally carried out by specialist companies and comprise of an organised report outlining the issues and design considerations required for a plot of land.

Any site in a flood zone 2 or 3 is obliged to have one to supplement planning applications and a decision may rely upon the assessment together with a good quality topographical plan. Please note THS Concepts does not offer flood risk assessment reports, but you can learn more about flood risk assessment reports here.

Flood Risk Topographical Survey Drawing Example
Flood Risk Survey example

A topographical plan for a flood risk zone consists of a site visit and survey using a Total Station. The information obtained during the survey is then extracted and presented using CAD software in the form of a site plan. Whilst not as thorough as a conventional topographical plan, the key information regarding boundary positions, ground levels, tree locations and building perimeters are shown. If you require a full topographical survey or the gathering of specific data, this will not be a problem.
