Ten Questions to Ask About Seattle's Draft Comprehensive Plan Update
An architect explains why you should care about the city's plan for growth.

By Andrew Grant Houston
It’s December 2023, and as a local architect and housing advocate, I—along with many other Seattleites—have now been waiting more than eight months since the city’s initial April release date for the Draft Environmental Impact Statement (DEIS) on the Housing Element of Seattle’s Comprehensive Plan Update.
The DEIS currently identifies five possible paths for Seattle’s growth over the next 20 years and how that growth—or lack thereof—will impact our urban and natural environment.
Although the Comprehensive Plan is a complete vision that includes a number of elements (as defined by the state’s Growth Management Act), typically the most contentious and complex of these elements is the Housing Element, which sets the upper limit for how many housing units Seattle will plan for in the next 20 years. This element, and the public engagement that will come with it, is a once-in-a-decade opportunity for Seattle residents to voice our views about whether that the number of homes in Seattle is sufficient or insufficient for us as well as future Seattleites, and to weigh in on where new homes should be added.
The city of Seattle has delayed releasing the draft statement multiple times, which should tip you off as to just how critical the Housing Element update is. But if you aren’t the sort of person who spends their time either wishing Seattle looked more like Paris or hoping your neighborhood will be preserved in amber until the end of time, what are the questions you should be asking yourself as you attempt to engage with such an important topic? There are certainly a multitude, but here are my top 10.
Population Growth
In May, the Seattle Times reported that, according to census data, Seattle is the fastest-growing large city in the United States. How does this news change the proposed number of housing units in the EIS draft, given that people are moving here faster than new homes are being produced?
Planned Growth vs. Actual Growth
How does the housing allocation proposed in the previous Comprehensive Plan, compared to actual housing production since that time, influence the proposed number of units in the Draft EIS, given our current housing deficit?
Zoning Capacity vs. What is Actually Built
New buildings typically have a lifespan of 50 to 100 years, meaning that there are tracts of land that have been developed since the previous Comprehensive Plan that may see zoning changes but will not see any actual increases in housing over the next 20 years. Are these parcels included in calculations around achieving increased housing capacity as part of the Draft EIS, or are they excluded?
Mandatory Housing Affordability
How is the Mandatory Housing Affordability (MHA) program being factored into the number of proposed housing units, given that the Community Indicators Report (September 2020) released by the City’s Equitable Development Initiative identified a need for 68,000 “affordable” units at all income levels below 80 percent of Seattle’s area median income, as well as the latest numbers from the city on MHA showing that just 7 percent of all housing units created over the last year qualify as “affordable?”
Homelessness
King County’s Point in Time count showed an increase in unsheltered individuals in 2022 compared to 2020, from 11,751 to 13,368. How does this increase in unsheltered homelessness influence the types of housing allowed as part of the Comprehensive Plan, as well as the allowed uses across Seattle?
The Urban Village (UV) Strategy
The Seattle Planning Commission’s 2020 paper “Evolving Seattle’s Growth Strategy” noted that the current Urban Village strategy perpetuated inequities that have existed in Seattle land use patterns since the creation of the city. A focus on equality would allow more homes in all neighborhoods, whereas a focus on equity would allow more homes in formerly redlined areas and neighborhoods that have seen little to no change in zoning since the implementation of the Urban Village strategy in 1994. Does the draft EIS address this and if so, how?
The 15-Minute City
How does the concept of creating a “15-Minute City” influence where the city will allow commercial or non-residential uses in each neighborhood? How does this inform the minimum number of homes we will allow on every lot in Seattle?
Climate Refugees
In 2023, we’ve seen a massive increase in heat waves across the US and in other countries. Given Seattle’s relatively mild climate, as well as the city’s status as a sanctuary city, how does the potential increase in climate refugees over the next 20 years the plan covers influence the number of proposed housing units across the city?
Trees
What methodology is being used to ensure that the tree canopy across the city is preserved or increased while also taking into account reductions in the buildable area on individual lots that may be necessary to achieve this goal?
The Climate Future of South Park
At the beginning of this year, South Park experienced a king tide, which flooded the neighborhood. Given that climate change will increase instances of this kind of phenomenon, including rising sea levels, does the Comprehensive Plan consider any forms of managed retreat and the impact climate change will have on proposed housing and development capacity in South Park and around the Duwamish floodplain?
The questions I’ve outlined above may appear intimidating, but I share them because, just as an informed voter is the best kind of voter, an informed citizen is the best kind of citizen. Seattle must change the way we do business in order to become the city we all wish it was for every resident—a place where everyone can work, live, and play safely and in community together.
But in order to get there we must first map the difficult road ahead. We must recognize that we are in a tumultuous time but that by working together we make overcoming the major issues our city faces that much easier for all of us. The Draft EIS must be the first plan for how we move forward, toward a Seattle for everyone. And if the city tries to turn away from this path, whether due to fear or a delusional sense of nostalgia, it’s up to us to collectively reject that false future.
When the draft plan is released, I encourage everyone in Seattle to take just five minutes to make one comment on the plan. That comment can simply say “we need to be more ambitious in how many homes we’re planning for” or “we need to be honest about how many people want to live here.” The amount of good each comment could do for our city would mean a lot less time having to write op-eds like this and a lot more time spent out enjoying all the best aspects of what it means to live here.

Great questions Ace! Here’s another one: As an accumulated result of Seattle’s participatory planning process, how does the Comp Plan balance the needs and wants of existing residents with the needs and wants of people who don’t yet live here?
