Responding to reports of the continuing growth that the Puget Sound region will experience over the next 20 years, the Department of Planning and Development released a report on September 19th outlining the current development capacity of Seattle as a whole as well as its individual neighborhoods based on data up to April of this year.
State reporting agencies have estimated that the population of Seattle will increase by 20 percent with 120,000 people becoming residents of the city by 2035, equaling approximately 70,000 units. Additionally, employment is expected to increase by 23 percent with 115,000 new jobs added.
To meet this demand, the DPD’s Development Capacity Report estimates that Seattle has the capacity to add an additional 223,700 housing units under current zoning, as well as 232,000 new jobs. The report defines development capacity as “an estimate of how much new development could occur theoretically over an unlimited time period,” as well as clarifying how the DPD calculated this estimate.

“First, the model identifies which parcels could be available for development,” states the DPD in the report. “This includes vacant parcels as well as underdeveloped parcels. Second, the model estimates what type of development is likely to occur on that parcel. Last, the model calculates the difference between potential and existing development.”
The DPD stated that this data will be used to measure the potential impact of infrastructure growth on the environment, transit, and public facilities as well as whether changes to zoning laws will be required. Additionally, the DPD emphasized that although the capacity to meet demand is present, certain areas may be upzoned to promote “strategic growth” of certain areas, such as areas affected by the addition of the LINK light rail system.
For Capitol Hill, which currently contains 14,219 housing units occupying 1,627 parcels of land, the DPD’s report found that 552 parcels were considered vacant or underdeveloped when compared to the potential level allowed for on that parcel, and are therefore considered likely to redevelop in the years between now and 2035.
If redevelopment were to occur for these 552 parcels, the neighborhood could add an additional 5,431 mixed-use units added in that time period.
The entire First Hill/Capitol Hill Urban Center, which includes First Hill, the Pike/Pine corridor and the 12th Avenue business district in addition to Capitol Hill proper, has a total of 26,635 existing residential units across 2,680 parcels of land. 914 are considered vacant or underdeveloped, equaling a growth capacity of 19,009 potential new residential units by 2035.

First Hill has the largest development capacity for residential units of the combined area with the potential to add a further 9,336 units to the current amount of 6,631. 12th Avenue, which has the lowest number of residential units in the combined area at 1,957, also has the least capacity for residential growth at 1,615 units to be potentially added. Pike/Pine, which has 3,828 current units, has the capacity to add another 2,627 units.
However, in terms of employment, the report found that current zoning will only allow for the addition of an estimated 629 jobs to Capitol Hill’s existing employment level of 5,962. In total, the First Hill / Capitol Hill Urban Center has a current employment level of 40,090 jobs and the capacity to add a further 3,186.
First Hill also boasted the largest capacity for commercial development with the potential to add another 1,005 jobs to its existing level of 22,029, while 12th Avenue could add 949 jobs to its current amount of 5,242. The heavily-developed Pike/Pine corridor sports the lowest potential redevelopment capacity for employment with the potential to add only 603 new jobs to its current number of 6,857.
