  • General Plans 1828-1974 (ACC 2423/X/001-300) A collection of more general plans relating to projects focusing on improvements to the Lea River and Navigation, the Stort River and Navigation, the Bow Back Rivers and the Grand Union Canal.

  • Administrative and Legal Documents 1829-1977 (ACC 2423/AL/001-119) Administrative files relating to accidents and damage, together with inventories of assets, minutes of meetings, and engineers' reports. Legal documents include material on agreements for sale and tenancy, the conveyance of property, and contracts.
