This bill updates Washington’s Growth Management Act requirements to ensure counties and cities regularly review and revise their comprehensive land use plans—every 10 years—with special attention to urban growth areas, critical areas, and climate resilience. It adds flexibility for very small cities and rural watersheds while requiring more detailed progress reporting from fast-growing areas.

  • Requires counties and cities to review and revise their comprehensive plans and development regulations every 10 years (starting between 2024 and 2027, depending on jurisdiction), with earlier deadlines for high-growth counties like King, Pierce, and Snohomish.
  • Allows small cities (population < 500, low growth, not near large cities) to opt out of full plan reviews but still requires updates to critical areas, capital facilities, and transportation elements.
  • Mandates that counties review and revise urban growth areas every 10 years to accommodate projected growth over the next 20 years, with strict limits on expansion (e.g., no net increase in total area, no conversion of high-value farmland, and no increase in rural land pressure).
  • Requires larger cities and high-density, fast-growing counties to submit implementation progress reports every 5 years, detailing progress on housing, permitting timelines, and climate action goals.
  • Strengthens public participation rules—requiring annual public schedules for plan updates and ensuring notice and comment opportunities for all major revisions, especially during emergencies or legal appeals.

Who is affected

  • Small rural cities (population < 500)Small cities with fewer than 500 people, not near large cities, and with low population growth may opt out of full plan reviews but must still update critical areas, capital facilities, and transportation elements.
  • All counties and cities in WashingtonCounties and cities must conduct periodic reviews of their comprehensive plans and development regulations every 10 years (starting in 2024–2027, depending on location), including updates to critical areas, urban growth areas, and housing elements.
  • Medium-to-large cities in fast-growing countiesLarger cities (population > 6,000 as of April 1, 2021) in high-growth or high-density counties must submit implementation progress reports every 5 years after their plan review, including details on housing, permitting, and climate actions.
  • Rural counties in agricultural watersheds with special agreementsCounties in participating watersheds that have elected special agricultural flexibility may delay updates to critical areas regulations for agricultural activities—unless specific triggers occur (e.g., court orders, health threats, or 3+ years since funding).
Effective: June 7, 2025Fiscal impact: The bill does not specify direct costs or savings, but it may increase state and local costs due to more frequent reviews, public participation efforts, and implementation reporting—especially for counties and cities required to submit implementation progress reports. State agencies are encouraged to provide technical assistance, but no new funding is allocated.

Pro/Con Analysis

Stronger case for benefits

Potential Benefits (5)
  • Mandates 10-year plan reviews with earlier deadlines for high-growth counties (e.g., King, Pierce, Snohomish), promoting more consistent and timely updates to housing elements—helping align land use with population growth and potentially easing housing shortages over time.

    HousingPeopleRef: Sec. 1(5)(a)-(d)
  • Requires high-growth counties and large cities to submit 5-year implementation progress reports covering housing affordability, permitting timelines, and climate actions—creating accountability for housing production and potentially accelerating permitting reforms and affordable housing supply.

    HousingPeopleRef: Sec. 1(9)(a)-(c)
  • Imposes strict limits on urban growth area expansion—no net increase in total area, no conversion of high-value farmland, and no increase in rural land pressure—helping preserve agricultural land, reduce sprawl, and curb carbon emissions from longer commutes.

    EnvironmentPeopleRef: Sec. 1(3)(c)(i)-(viii)
  • Requires annual public participation schedules and notice/comment opportunities for all major plan revisions—increasing transparency and civic engagement in land-use decisions, especially for vulnerable communities often excluded from planning processes.

    Local GovernmentPeopleRef: Sec. 1(2)(a)
  • Allows very small cities (<500 pop., low growth, remote from major cities) to opt out of full plan reviews—reducing regulatory burden on resource-constrained rural towns while still requiring updates to critical areas, capital facilities, and transportation elements.

    Local GovernmentLean peopleRef: Sec. 1(1)(b)
Potential Concerns (5)
  • Mandates more frequent comprehensive plan reviews (every 10 years, with earlier deadlines for high-growth counties), increasing administrative and staffing burdens on local governments—especially smaller jurisdictions without dedicated planning staff—without state funding to offset costs.

    Local GovernmentPeopleRef: Sec. 1(5)(a)-(d)
  • Imposes new 5-year implementation progress reporting requirements on medium-to-large cities and fast-growing counties, requiring staff time and technical analysis for housing, permitting, and climate metrics—diverting limited local resources from direct service delivery.

    Local GovernmentPeopleRef: Sec. 1(9)
  • Allows emergency or appeal-related plan amendments outside annual public schedules, potentially reducing public input during urgent legal or political pressures—undermining transparency in land-use decisions that directly affect property rights.

    Rights & LibertiesLean peopleRef: Sec. 1(2)(a)(v), (b)
  • Permits rural counties with agricultural watershed agreements to delay critical areas updates for up to 3 years—or indefinitely if benchmarks are met—risking degraded water quality, habitat loss, and long-term ecological harm in sensitive rural zones.

    EnvironmentLean peopleRef: Sec. 1(8)(a)-(c)
  • Allows small cities (<500 pop.) to opt out of full plan reviews but still require critical areas, capital facilities, and transportation updates—creating inconsistent regulatory burdens where small towns face disproportionate compliance costs relative to capacity, potentially discouraging growth and housing development.

Who Is Most Affected

Small rural cities (population < 500)Mixed Impact

Small rural cities (<500 pop.) benefit from reduced planning burden but still face costs for critical areas and infrastructure updates; many lack dedicated planning staff, so even partial compliance can strain local budgets and volunteer boards.

Medium-to-large cities in fast-growing countiesPositive Impact

High-growth counties and large cities face new reporting and planning obligations but gain long-term benefits from structured housing and climate accountability; these jurisdictions have more staff and resources to comply, giving them an advantage in accessing state grants tied to compliance.

Rural counties in agricultural watersheds with special agreementsMixed Impact

Rural counties in agricultural watersheds gain flexibility to delay critical areas updates if benchmarks are met, but risk environmental degradation and future legal liability if benchmarks are not sustained; the 3-year extension clause may delay necessary protections.

All counties and cities in WashingtonNegative Impact

All counties and cities must comply with more frequent plan reviews and public participation rules, increasing administrative costs without new funding—though compliance may improve long-term resilience and reduce costly legal challenges to land-use decisions.

Homebuyers and rentersPositive Impact

Homebuyers and renters benefit from increased accountability for housing production and climate-resilient planning in high-growth areas, potentially easing supply constraints and reducing exposure to climate-related property damage over time.
