Isle of Man Government: Planning Committee: Planning application index maps A collection of Ordnance Survey County Series and National Grid maps for the Isle of Man that serve as an index to planning applications submitted to the Isle of Man Government from 1936 to the 1990s. The maps are annotated with planning application reference numbers for individual properties and land. This system was likely established by the Development Board in the 1930s and was in use until the late twentieth century (1999), when the Planning division began using an electronic database to record planning applications. These maps form the main starting point for searching the Isle of Man historic planning application filing system. The early index maps, covering planning application submitted to the Development Board from 1936 onwards, are annotated onto Ordnance County Series maps (sub-series S90/1) and County Series Town plans (sub-series S90/2) to 1:2500 scale (and 1:1250 scale for Douglas and Onchan). When Ordnance Survey established the National Grid system in the mid 20th century, the new resulting maps were adopted for built up areas of the Island, providing more space for recording application numbers. These National Grid maps can be found in sub-series S90/3 and S90/4. The planning reference numbers already on the County Series maps were not transferred to the National Grid maps, and so it is necessary to consult both sets of maps to search for applications for some areas of the Island. For some rural areas where there has been limited development, no National Grid maps are available and all planning references appear on the County Series maps. The reference numbers used for planning applications following a running number from 1 to 57073 (from 1936-1983). In 1982, Tynwald approved the Isle of Man Planning Scheme (Development Plan) Provisional Order, which brought changes to the Planning Commitee. This was reflected in a change to the reference number systemFrom 1983, planning reference numbers include the year followed by the number they are assiged with on registration (e.g.: 83/2378) To use the index maps: - Identify the map sheets (both Ordnance Survey and National Grid) where the property is located. This can be done by referring to the overview index map sheets at the start of each sub-series; - Consult the individual map sheets for the particular area of the Island, find the property itself on the maps and note down any planning application numbers written on the maps for that property. The application numbers identified on the index maps can then be researched further using the planning application registers (catalogue reference S89), planning application files (catalogue reference S10) and planning committee minutes (catalogue reference S92). The index plans are in paper format, but a set of digital scans of the index maps are available (with the exception of the National Grid scale 1:10560 plans in S90/4). These can be viewed online by clicking the link on each online catalogue entry. 1936-1999
