Planning applications for most developments now require a surface water management (SuDS) report, detailing how the surface water is to be managed on site; discharged off site and not increasing the flood risk to areas within or near the site.

Flo can provide a surface water management report; calculations and details for planning applications which will include:

• Surface water discharge destination hierarchy analysis;

• Sustainable drainage (SuDS) hierarchy analysis;

• Development plans showing the topography; SuDS systems; watercourses; and exceedance routes;

• Pre-development and post-development SuDS flow calculations for the 1 in 1-year storm to the 1 in 100-year storm including climate change using MicroDrainage WinDes computer software;

• SuDS flow calculation for the volume of attenuation required using MicroDrainage WinDes computer software;

• Details of pollution prevention measures;

• Detailed flood and drainage design drawings and layouts including details of inlets, outlets and flow controls, and exceedance routes;

• Management and maintenance regime for all elements of the SuDS system;

• Evidence of necessary third-party agreements for discharge.
