When the drainage by gravity of any locality is such that in the opinion of the police juries of the respective parishes, it becomes necessary to organize or create gravity drainage districts composed partly of land situated in two or more parishes, then the drainage districts may be created by joint resolution of the police juries of the respective parishes, or by a resolution to that effect passed by the police jury of one parish and approved by the police jury or juries of the other parish or parishes. The police juries shall create the district upon a petition being presented to them as provided in R.S. 38:1751 covering the creation of gravity drainage districts from lands lying in one parish.
