Requirements for major applications (submitted in OUTLINE)

Applications must be submitted with a concept SuDS plan and preliminary SuDS design strategy which may include the following:

• details of how runoff is collected from roofs, roads and other hard surfaces to keep water at or near the surface
• source control techniques for each sub-catchment
• site control features with approximate volumes and flow control locations and details
• flow routes including low flow, overflow and exceeding routes
• confirmation of conveyance features from place to place
• confirmation of appropriate “treatment stages” within each “sub-catchment” and “management train”
• confirmation of sub-catchments with location of flow controls
• regional (catchment) controls in public open space where appropriate
• confirm and demonstrate how the SUDS are integrated into the landscape, with sketches and sections as appropriate, including a management plan for the development
• confirm the destination of the “controlled flow of clean water” from the site – the ground by infiltration, a watercourse or the surface water sewer.
