VPRS 12758 Index Map Book

In 1892 the recently formed MMBW had contractors survey Melbourne as part of the task of establishing the metropolitan sewerage system. The survey fixed the location of structures within allotments and the associated levels.As a result of the survey a number of different types of records were created that documented the urban structure at the time and for the next 80 years. As the record system was understood in 2000, the systems major elements were:* Survey field books books used by surveyors to record their field observations.* Survey level books books that record levels above and below a datum point.* One inch to forty feet plans and their metric successors used for the location of structures and the sewerage system (including Detail Plans [DP], Sewerage Plans and Property Service plans). Lithographic copies of the forty feet to one inch plans were produced for distribution and working purposes and, later, plate photographic negatives of the DP and sewerage plans were made. Microfilm copies of house connections files containing Property Service plans were made in the 1970s and the 1980s.* Plans of other scales.* Index maps maps that index other maps and plans.
