Comment

Having looked at the site from an ordinary watercourse, surface water and ground water flooding point of view we have the following comments:

Drainage Category 2 - The site could be drained by sustainable drainage, however there are constraints and these need to be considered in the design

Reason – Potential risk from Parish Brook which runs along the boundary of the site. Parish Brook will need modelling.  Small areas of 1 in 30 surface water risk

infiltration/soakaway test required and consider whether infiltration can be used as a SuDS technique alongside water storage (in ponds/chambers) and re-use
