2.14. Fluvial flooding from the Angarrack Stream and Loggan’s Mill leat, located to the west of
the Loggan’s Moor roundabout, is reported to have occurred to the south-west of the
roundabout and downstream of the site on seven occasions since 1966.
2.15. Unauthorised operation of a sluice in the Angarrack Stream system north of the site is
reported to have led to flooding in 1983. Overtopping of a fluvial channel is understood to
have caused flooding of farmland close to the former sewage treatment works to the
north-east of the site in 1985.
2.16. Pluvial flooding from surface water run-off occurred at Golden Sands caravan park and
along Marsh Lane and Guildford Road to the south-west of Loggan’s Moor roundabout on
four occasions between 1986 and 1994. No flooding events along Marsh Lane to the
east of Loggan’s Moor roundabout have been reported.
