 New toolkit helps bring community voices to local planning
Meaningful community engagement is vital to any successful planning effort. Local voices should be heard at every stage, especially when community members may be unfamiliar with the planning process or how to give input.
Now, Commerce has a new resource to help bring those voices to the table.
The Plan Together, Grow Together toolkit includes a video, graphic novel and workbook designed to introduce core concepts around comprehensive planning and ways community-based organizations can get involved.
Commerce developed the toolkit in partnership with local governments and community-based organizations across Washington as part of the Advancing Meaningful Engagement pilot program.

Washington population growth is slowing, OFM says
Washington’s population continues to grow, though at a much slower rate than it did during the last decade, according to the latest population estimates released by the Office of Financial Management.
OFM reported the state’s population had grown by 79,400 to 8.1 million people as of April 1. Net migration, the main driver of population growth, fell to the lowest level (outside of the COVID-19 pandemic) since 2013.

Commerce tool can estimate middle housing returns
Commerce has an updated resource to estimate financial feasibility for middle housing projects. The Middle Housing Pro-Forma Tool, which was previously applicable only to Puget Sound, has been revised for use across the state.
Pro-formas are essentially a developer's way of evaluating a real estate project to see if it makes financial sense. Commerce’s middle housing pro-forma can be used to model many middle housing building types and provide estimates of local construction costs, rents and sales prices.
Unit lot subdivisions fact sheet updated
Commerce has revised its Unit Lot Subdivisions fact sheet to reflect updates to state law made during the 2025 legislative session. The fact sheet now reflects Chapter 271, Laws of 2025 (SB 5559), which provides guidance on how unit lot subdivisions are defined and processed
For questions, contact Lilith Vespier at [email protected].

Draft statewide transportation plan available for public review
The Washington State Transportation Commission released its draft 20-year transportation plan and is asking for review and feedback by Friday, July 18.
The Washington Transportation Plan Vision 2050 provides a high-level policy transportation blueprint for the state, counties, cities, and transportation operators to use in crafting their transportation plans. The plan was shaped through engagement with city and county governments, regional planning organizations, state transportation agencies, tribes, private-sector partners, and the public.
Comments on the draft plan can be emailed to [email protected] or submitted via an online form. The commission is expected to adopt the final plan later this summer.

Ecology adding new Chapter 173-217 WAC – State Waters Alteration Permit
Ecology initiated state rulemaking to add a new chapter to Washington Administrative Code (WAC) establishing State Waters Alteration Permit (SWAP), a formal permitting program for projects that could alter or impact state waters.
Currently, Ecology issues administrative orders under the Water Pollution Contract Act to authorize projects seeking to alter or impact state waters (including those no longer federally regulated). While administrative orders protect the environment, the process lacks public notice opportunities and timeline obligations for issuing decisions. A new state permitting program would replace the current administrative order process and provide positive customer service benefits by:
- Providing better clarity and predictability about our actions and requirements
- Creating general permits to streamline approvals for projects with minor impacts
- Establishing opportunities for public review
- Setting mitigation requirements for projects
Ecology filed the SWAP Rulemaking Announcement (CR-101) on June 10. Ecology will work with the public and interested parties through the GovDelivery email list as they develop rule language. Ecology will start the informal feedback period with the first tribal information session July 30 and first public information session July 31.
Please visit Ecology’s rulemaking webpage for more information or contact Sonal Gangawala Khanna, rulemaking lead, at [email protected].
