Administrative / Biographical History

The Board of Trade and its successors were responsible for approving plans for works and improvements in relation to railways, docks, fisheries, dredging, sewerage, sea walls, piers and harbours. The maps and plans submitted to them show works constructed on Crown foreshore land and were used as legal proof of Crown ownership of the foreshore and to regulate foreshore development to provide for safe navigation. The General Department of the Board of Trade administered this from 1840 but was amalgamated with other departments at intervals up to the 1980s, by which time authority rested with the Department of Transport for works such as piers, slipways and bridges and with the Commissioners of the Crown Estates for the general foreshore.
