A rural community, Downside (and the adjacent hamlet of
Hatchford) is situated in open countryside between
Cobham to the north and
East Horsley to the south,
Stoke D'Abernon to the east and two similar size settlements across the
Surrey Wildlife Trust expanse of Wisley Heath and Ockham Common:
Ockham and
Wisley to the west. London is northeast, Guildford is southwest. Local administrative centre of Elmbridge,
Esher , is
NNE. This elevated community is part of the
Green Belt. Immediately to the south of the village is the
M25 motorway, where construction of a motorway service station began, despite determined local opposition, in 2011. To the north is
Cobham Park, a large country house that has been converted to apartments. Downside has a large
village green, on the northern edge of which is the Cricketers'
Inn, dating at its core to the 17th century and a Grade II
listed building. Immediately off the green in the south east corner is a listed hand-operated water pump.
Elevations, soils and geology Elevations of the central part of Downside, on all sides of the Common vary from
AOD in the southwest to
Above Ordnance Datum in the northeast, while the common itself ranges between 29-33m AOD. Immediately north of this the
River Mole begins to cut a valley and in Cobham, most of which, excluding
Fairmile is at 18-22m
AOD. Not within the narrow belt of raised soils of the north Surrey belt of acidic, sandy raised
heathland of the
Bagshot Formation, the soil stretching from Cobham and Downside as far as
Effingham and for a more considerable distance east and southwest is "slowly permeable loamy/clayey slightly acid but base-rich soil", which gives rise to
flora of trees, grasses and crops or which can be cultivated easily. As the later sandy soil mentioned above and certainly further chalk overlayers have been washed away, whereas sand may have been scant, hence why it appears further north; the geology of Downside is
Cretaceous: i.e.
Hastings Beds,
Weald Clay, then
pleistocene Folkestone and then covered by a considerable remaining layer of
Claygate Beds,
Gault Clay mixed in with some eroded
limestone from the north downs in the soil to the south. ==Demography==
