Description:

Abstract:

Boundaries of the Spheres of Influence of Napa County Cities.Last updated 2017

Purpose:

To show the area of the Sphere of Influence for each city in Napa County

Supplemental information:

A sphere of influence is a planning boundary outside of a city's legal boundary that designates the city's probable future boundary. This file was created  from LAFCO's hard-copy map  tax rate area (TRA) database provided by the County of Napa Assessor. The hard-copy maps used to generate this layer are available from LAFCO.
