Watching brief of topsoil stripping by S P Dyer for SCAU and Cairn Energy PLC. No features of archaeological interest were observed. (265)

Fieldwork by R Ellaby and D W Williams in advance of golf course construction revealed no sites of interest except a late limekiln, but only limited work was possible.

A prominent brick tower is identified by P Sowan as an observatory for surveying the line of the Merstham Tunnel on the London & Brighton Railway Company line constructed in 1838-41. The structure is described and the possibility of its present appearance resulting from later modifications is discussed. (SIHG 76) Four substantial square brick pillars linked at the top with iron ties are identified by P Sowan as the remains of an observatory for the surveying of a tunnel on the London Brighton & South Coast Railway's Quarry Line, which opened in 1899.

Remains of buffer depot 124, one of a series built between November 1941 and December 1942 and used for storage of supplies in the Second World War and subsequent ‘cold war’ located by P Sowan. (SIHG 74)

Evaluation trial trenching by S P Dyer for SCAU and SCC failed to locate any finds or features earlier than the 19th century. (278)

Evaluation by trial trenching in advance of redevelopment, by G R Pattison of SCAU for Surrey County Council, revealed two medieval ditches, possibly early field boundaries, and an undated hearth and gully.

Test excavation some years previously by R Masefield of a possible RB tile production site located a large pit feature filled with 550 fragments of RB tile. They included much waster material represented by partially fired, overfired and distorted material, and a range of tile types, including roof, flue and hypocaust tiles. Fabric analysis by I Betts at the Museum of London demonstrated that the Reigate tilery had been supplying tiles to major sites in London. (282; see report in SyAC 90, 247-259)

Observation of foundation trenches by S P Dyer for SCAU and the Hancock Ward Company did not reveal anything of archaeological interest, probably because of levelling at some time in the past. (279)

Observation of works within the Cage by S P Dyer for SCAU and the Hancock Ward Company located two floor levels, but the lowest is thought to have been not more than 100 years old. There were no other discoveries of archaeological interest. (279)

Observation by D W Williams for the Hygate Partnership of the digging of foundation trenches revealed a stone wall probably dated post 1800 with an associated chalk surface. Beneath this surface deposits of late 12th/early 13th century date were found. (280)
