Marysville finds no significant environmental impact from housing and zoning changes
The city issued a determination that its state-required housing and zoning amendments won't significantly harm the environment, with appeals due June 20, 2025. 1
What the records say
On June 6, 2025, the City of Marysville issued a Determination of Non-Significance (DNS) for its proposed housing and zoning code amendments. A DNS means the city reviewed the proposal and decided it will not have a probable significant adverse impact on the environment, so no environmental impact statement (EIS) is required. 1
- The city issued a Determination of Non-Significance on June 6, 2025, finding the proposal won't have a significant adverse environmental impact, so no environmental impact statement is required. 1
- The amendments respond to state mandates: House Bill 1110 (middle housing in residential zones), House Bill 1337 (accessory dwelling units), and House Bill 5258 (unit lot subdivisions). 1
- The city proposes to rezone existing single-family zones (R-4.5, R-6.5, R-8, and WR-R-4-8) to a Neighborhood Residential zone, and to add the Residential Mobile Home Park zone to the comprehensive plan map for existing parks. 1
- The mobile home park map change applies to Crystal Tree Village, Emerald Hills Estates, Glenwood Mobile Estates, and La Tierra. 1
- Because the DNS used the optional process, there is no further public comment period. Appeals must be filed in writing by 4 p.m. on June 20, 2025, with a $500 filing fee. 1
Why it matters
The amendments would allow more housing types in neighborhoods currently zoned for single-family homes, including middle housing, accessory dwelling units, and unit lot subdivisions. The city would also add existing mobile home parks to the comprehensive plan map. 1 Analysis: The DNS is a procedural step; it does not adopt the changes, but it clears an environmental review hurdle before the city moves forward.
