Comprehensive Plans

Master and Subarea Plans

Master plans

A master plan is a land use plan focused on one or more sites within an area that identifies access, general improvements and needed infrastructure. These plans are intended to guide growth, development, and improvements over a number of years and in phases.

Subarea plans

Every community is made up of smaller areas, each with its own set of unique attributes, issues, opportunities and challenges that contribute to the whole. Subarea plans are targeted for these smaller areas and provide a way to help the residents and businesses in these areas, such as corridors, neighborhoods, etc., figure out how their area fits into the “big picture” in terms of achieving the overall goals of the comprehensive plan, while addressing issues or concerns of particular importance to the small area. These might include dealing with an aging mall or vacant businesses, increased traffic flow, development densities along corridors and how to make the density “fit” into the neighborhood, and how to address walkability, connectivity, and open space. 

The city has adopted detailed Subarea Plans for several of the centers where focused growth is anticipated. Subarea Plans include detailed Comprehensive Plan land use designations, and development standards that are the zoning for the areas.  

Smokey Point Master Plan


Marysville is engaged in an aggressive economic development strategy to establish a prosperous economic future by creating a climate conducive to business. Marysville’s economy is characterized by a healthy mix of small business, corporate headquarters, aerospace and composites companies, light industrial and manufacturing, and service sector business.

The 675-acre Smokey Point Master Plan area constitutes the largest developable concentration of commercial and light industrial-zoned property along I-5 from the U.S.-Canadian border to south of Seattle-Tacoma. Its proximity to Arlington Municipal Airport and the City’s Airport Business Park expansion plans makes this area an economic development oasis.

The Smokey Point area is master planned with the potential to create 10,000 jobs in high-tech, other light industry, aerospace and other manufacturing. These are jobs that can support families and reduce travel times for commuters so that they have more time to spend with their families.

Three I-5 interchanges, including 116th and 172nd exits, provide access to the master plan area. 156th Street overcrossing, funded through a partnership of the City and property owners, opened in November 2012 and will provide even better access to the Smokey Point area. Working together with our neighbors the Tulalip Tribes, City of Arlington, Snohomish County and other economic partners, we are building toward a sounder regional economy.
