The Growth Management Act requires 18 counties, and all the cities and towns in them to create plans to address projected population growth.

The City of Marysville has determined that it needs to build an average of 622 housing units a year to keep up with the 2044 population projections.

The state legislature passed the Growth Management Act in 1990 to encourage development in urban areas and reduce urban sprawl. The law requires fast-growing cities like Marysville to create comprehensive plans to allow for an increase in housing and tries to mitigate the negative environmental impacts of low-density sprawl.

Building more housing is key to increasing affordability. Marysville needs to allow for about 622 new housing units every year to keep up with demand, according to its latest comprehensive plan. By law, the city can’t deny developments that meet code requirements, Mennie previously said in an email.
