No gravity drainage district shall be created comprising the whole territory of a parish, nor shall it contain, within its limits, less than five landowners. The police jury, with the concurrence of the drainage commission may at any time prior to the incurring of debt, issuing of bonds, or levying tax, change the boundaries of the drainage district, so as to enlarge or diminish the limits, or to repeal entirely the ordinance creating the drainage district.
