In 1918 the drainage legislation was reviewed and new concepts were introduced which proved to be unsatisfactory in certain regards, The 1918 Act gave Drainage Commissioners the option of laying drainage rates on an acreage basis or on annual value. In 1918 the Ministry decreed that lands which could be rated for direct benefit were the agricultural land below the 8ft (based on 8 ft of wheat roots) contour above the highest known local flood level; urban property was set at flood level. Agricultural land assessment at the coast was based on 5ft above spring tide level for benefit, The Act also set out the flood benefit criteria lines, Rates were usually established on the acreage basis as it was easier to administer. |t was difficult to raise sufficient money under that arrangement, Only lands which received benefit paid prior to 1930. The Land Drainage Act of 1930 (1) created one authority (Catchment Board) for each main basin; (2) departed from the principle of assessing all the cost of drainage against land in proportion to direct benefit; and (3) established the principle of government grants-in-aid for agricul tural land, There were 20,000 miles of main river.
