Flood Risk Assessments

Using the new GPS based OS Active Network RG Surveys can quickly relate your site to the OS datum.

Site surveys can be carried out based on the OS GPS levels and grid, allowing easy risk assessment to flood.

Additional information can also be collected and related to the site survey and OS datum. This would include surveying the flood risk itself, obtaining bed levels, water levels and river bank heights. The route to your site from the risk could also be surveyed along with any possible defenses and dry means of escape from your site.

From the Environment Agency the 1 in 100 year flood level for your site could be obtained and plotted as a contour where it falls in relation to the completed survey.

The completed survey in OS grid and levels showing the site survey including, the flood risk, the route to the site, the escape route from the site and the 1 in 100 year flood level makes a very effective tool in an application for developing a site that is under threat from a flood risk.
