Assessments are used to fund the day-to-day maintenance of the levees, canals, pump stations, small capital projects, and the first response during a flood emergency for those who reside within the boundaries of RD1000. Property assessments are collected by the local property taxing authority, the Sacramento County Tax Collector, and the Sutter County Tax Collector.

The assessment for each property is determined by its location, the size of the parcel, and its land use (eg: residential, commercial, industrial, or agricultural) and the relative benefit assigned to that land use. 

A typical single-family home on an urban residential lot will pay $25 per year for essential direct public safety benefits to all of our residents. The District is divided into several geographic zones of benefit based on the potential depth of flooding should the perimeter levee system fail as well as interior drainage services provided by the District. The District's annual operations and maintenance costs are spread proportionally among the properties within Natomas.
