RCW 70A.45.120
Local government comprehensive plans—Housing capacity and emissions reduction—Department guidelines.
(1) The department of commerce, in consultation with the department of ecology, the department of health, and the department of transportation, shall publish guidelines that specify a set of measures counties and cities may implement via updates to their comprehensive plans and development regulations that have a demonstrated ability to increase housing capacity within urban growth areas or reduce greenhouse gas emissions, allowing for consideration of the emissions reductions achieved through the adoption of statewide programs. The guidelines must prioritize measures that benefit overburdened communities, including communities that have experienced disproportionate harm due to air pollution and may draw upon the most recent health disparities data from the department of health to identify high pollution areas and disproportionately burdened communities. These guidelines must be developed consistent with an environmental justice assessment pursuant to RCW 70A.02.060 and the guidelines must include environmental justice assessment processes. The guidelines must be based on:
(a) The most recent greenhouse gas emissions report prepared by the department of ecology and the department of commerce pursuant to RCW 70A.45.020(2);
(b) The most recent city and county population estimates prepared by the office of financial management pursuant to RCW 43.62.035;
(c) The locations of major employment centers and transit corridors, for the purpose of increasing housing supply in these areas; and
(d) Available environmental justice data and data regarding access to public transportation for people with disabilities and for vulnerable populations.
(2)(a) The department of commerce, in consultation with the department of transportation, shall publish guidelines that specify a set of measures counties and cities may have available to them to take through updates to their comprehensive plans and development regulations that have a demonstrated ability to reduce per capita vehicle miles traveled, including measures that are designed to be achievable throughout the state, including in small cities and rural cities.
(b) The guidelines must be based on:
(i) The most recent greenhouse gas emissions report prepared by the department of ecology and the department of commerce pursuant to RCW 70A.45.020(2);
(ii) The most recent city and county population estimates prepared by the office of financial management pursuant to RCW 43.62.035; and
(iii) The most recent summary of per capita vehicle miles traveled as compiled by the department of transportation.
(3) The department of commerce shall first publish the full set of guidelines described in subsections (1) and (2) of this section no later than December 31, 2025. The department of commerce shall update these guidelines at least every five years thereafter based on the most recently available data, and shall provide for a process for local governments and other parties to submit alternative actions for consideration for inclusion into the guidelines at least once per year. The department of commerce shall publish an intermediate set of guidelines no later than December 31, 2023, in order to be available for use by jurisdictions whose periodic updates are required by RCW 36.70A.130(5) to occur prior to December 31, 2025. Jurisdictions whose periodic updates are required by RCW 36.70A.130(5)(b) may utilize the intermediate set of guidelines published by the department of commerce to meet the requirements of RCW 36.70A.070(9).
(4)(a) In any updates to the guidelines published after 2025, the department of commerce shall include an evaluation of the impact that locally adopted climate change and resiliency elements have had on local greenhouse gas emissions and per capita vehicle miles traveled reduction goals. The evaluation must also address the impact that locally adopted greenhouse gas emissions reduction subelements have had on meeting local housing goals and targets.
(b) The updates must also include an estimate of the impacts that locally adopted climate change and resiliency elements will have on achieving local greenhouse gas emissions and per capita vehicle miles traveled reduction goals. The evaluation must also include an estimate of the impact that locally adopted greenhouse gas emissions reduction subelements will have on meeting local housing goals and targets.
(c) The department may include in the specified guidelines what additional measures cities and counties should take to make additional progress on local reduction goals, including any measures that increase housing capacity within urban growth areas.
(5) The department of commerce may not propose or adopt any guidelines that would include any form of a road usage charge or any fees or surcharges related to vehicle miles traveled.
(6) The department of commerce may not propose or adopt any guidelines that would direct or require local governments to regulate or tax, in any form, transportation service providers, delivery vehicles, or passenger vehicles.
(7) The department of commerce, in the course of implementing this section, shall provide and prioritize options that support increased housing supply and diversity of housing types that assist counties and cities in meeting greenhouse gas emissions reduction, housing supply, and other requirements established under this chapter.
(8) The provisions of this section as applied to the department of transportation are subject to the availability of amounts appropriated for this specific purpose.
(9) For purposes of this section, "overburdened communities" and "vulnerable populations" means the same as provided in RCW 36.70A.030.
