Approval-ready Sustainable Drainage System strategies for new developments under Schedule 3 of the Flood and Water Management Act. Hydraulic modelling, source control design, attenuation calculations, and SAB-compliant reports.
→ 02Drainage strategies, flood risk assessments, and surface water management plans for planning applications. Catchment analysis, runoff modelling, and integration with local authority requirements.
→ 03LiDAR-derived terrain models, contour analysis, and site classification that feed every drainage and SuDS deliverable we produce. The geospatial engine behind the consultancy.
→Every SuDS strategy starts with terrain. We build a 3D model of your site from LiDAR data and overlay the hydrological context: catchment boundaries, flow paths, infiltration potential, impermeable surfaces.
"Where does water go on this site, today and after development?" The model answers that before a single attenuation tank is sized.
SuDS design depends on understanding where water goes. We turn LiDAR-derived terrain into catchment boundaries, slope analysis, and impermeable-surface mapping at 1 m resolution.
The result: defensible runoff calculations, accurate attenuation sizing, and SuDS strategies that pass approval first time.
Most SuDS reports are still produced from desktop drawings and rough catchment estimates. Calculations happen in spreadsheets. Iteration is slow.
We start every project with real LiDAR-derived terrain. Catchments are delineated from actual elevation data, not eyeballed boundaries. Runoff is computed against measured surfaces. AI-assisted classification flags impermeable areas, building footprints, and vegetation in minutes, not days.
Every output carries a chartered ICE engineer's review and signature. The result: faster delivery, defensible numbers, strategies that pass SAB review first time.
