Pre-application and application

What is it?

Water is often the constraint nobody scoped for. Drainage assessment, hydrological survey and water environment advice establish how a scheme interacts with watercourses, groundwater and surface water drainage, and what is needed to satisfy both the planning authority and the relevant regulator.

When is it required?

Where a scheme affects a watercourse, alters drainage, or sits within or adjacent to a floodplain or designated water body, and wherever the authority raises water environment constraints.

What happens

  1. 01Review of existing drainage, watercourses and designated water bodies
  2. 02Hydrological survey where site conditions require it
  3. 03Assessment of effects on the water environment
  4. 04Mitigation and compliance recommendations

What happens next

Water environment work sits alongside ecological assessment rather than replacing it, and the two are stronger delivered together.
