This model law provides a template for Louisiana parishes wishing to implement a green space ordinance to preserve water resources. The model law creates a servitude on the property between the property owner and the parish government and is a mandatory prerequisite for the issuance of any and all building permits. The servitude provides for a certain percentage of land on a property that shall remain in a natural, undisturbed or revegetated state, and allows the parish to enter the land for random inspections or following a complaint; the parish has the authority to abate any violations at the expense of the property owner.
