The Green Line is a proposed long term boundary that helps define where Dixon plans for future urban growth to end. It also serves to provide notice to other governmental agencies that the City is interested in any proposed land use changes within this boundary. By including it in the Notice of Preparation (NOP), the City is setting a clear framework for planning ahead instead of reacting to ongoing, project-by-project development requests.

For residents, it provides a clearer sense of where urban development is intended to stop and where lower density or rural land uses are intended to remain, which helps reduce uncertainty about how the Dixon community may evolve over time.

For agricultural areas, it helps reinforce that certain lands are intended to stay in production and not transition into urban development, which supports long term preservation of farming uses in this area.

For the City, it creates a more stable planning boundary for infrastructure decisions regarding water supply, sewer service and roadway development. That makes it easier to design systems efficiently because planners are working from a defined growth area rather than a constantly shifting city footprint.
