“Buy land, they’re not making it anymore.” – Mark Twain
As Seattle’s development boom continues without any sign of stopping, the city is rapidly approaching a point where Downtown is completely built out and there is no land left to build on. In many ways this is a desirable situation. Urban density has clearly documented benefits for environmental sustainability, economic vitality, and public health. However, as Downtown sees more jobs and residents arrive, decades of sluggish planning are catching up and exposing voids in important public infrastructure and services. Downtown’s housing stock grew 127% between 1996 and 2015, now totaling over 24,000 homes, but residents have not been supported by parallel growth rates in capital facilities like schools and parks. Downtown–and more broadly the Center City–is the thriving cultural and economic hub of the region. It encompasses and borders a variety of high-density, mixed-income, and diverse residential neighborhoods like the International District, First Hill, and Belltown. It is home to important institutions, entertainment venues, and social services used by people from across the region and state. Because Downtown affects the health and success of so many people and places it must become a more complete neighborhood.Study Area
The following analysis examines one aspect of this goal: the availability of public infrastructure through the lens of land demand and land supply. The study area is the Downtown Urban Center between the waterfront and Interstate 5 and between Denny Way and Dearborn Street. This is approximately 1.3 square miles (830 acres).
Demand
The first step is determining the scale of the infrastructure needs. The focus here is on capital facilities which are intricately linked to the availability of land: affordable housing, public schools, community facilities, and parks. A future analysis may consider other infrastructure like public safety and utilities.Public Housing
It is essential that cooks, custodians, security guards, cashiers, and other Downtown workers have opportunities to leave near where they work. Short commutes by foot, bike, and transit in compact neighborhoods help people spend more time with their families and easily access daily needs. Public housing (defined here as housing either owned or subsidized by city government) is a key component of building a more affordable Downtown. While most of Seattle’s public housing projects are lowrise, the city has a history of taking advantage of highrise zoning in the central city. Seattle Housing Authority (SHA) developments in the study area include:- Chinatown-International District: 12-story International Terrace;
- West Edge: 12-story Ross Manor;
- Belltown: 13-story Bayview Tower and 17-story Bell Tower;
- First Hill: 17-story Jefferson Terrace; and
- Capitol Hill: 12-story Denny Terrace.

Schools
To support the education of the next generation, especially for kids who live in public housing, a major issue is the lack of public schools in Downtown. The Downtown Seattle Association (DSA) has long recognized this with its “family-friendly” task force, whose focus is siting an elementary school. The DSA points out, “children are the fastest-growing demographic in our center city. More than 1,900 children live west of I-5 in downtown.” While the DSA defines Downtown much more broadly to include parts of Capitol Hill and First Hill, the point stands. Seattle Public Schools (SPS) also recognizes this necessity and in 2015 tried purchasing the old Federal Reserve Building, a centrally located site with multi-modal access. However, SPS revoked their bid due when they learned about the costs of renovation.


Community Facilities
Community centers are a key component of neighborhood life in Seattle, hosting everything from fitness classes and language lessons to public forums and holiday festivals. The Seattle Parks and Recreation Department recently published a standalone Community Center Strategic Plan. Among many policies and aspirations, a key planning goal is “Each Urban Center of the City is to be served by a community center.” Downtown is one of those Urban Centers; a small facility does exist in Belltown, but the facility is leased and may not last amid development pressures. There are also edge centers in Yesler Terrace and Chinatown-International District, but given the pace and location of recent residential construction they may need reinforcement with additional capacity. Beyond Downtown, the neighboring Urban Centers of First Hill, Capitol Hill, and South Lake Union are in a similar situation. Downtown’s smaller neighborhoods are also due for their own branch libraries. After opening in 2004, the flagship Central Library has been wildly popular. In a 2008 interview with Seattle PI architect Joshua Prince-Ramus noted, “What makes me happiest is the volume of people who are in it. We programmed for 3,000 people to use it daily and its usage is double or triple that”. The Central Library was the last to open in the system, and in the meantime some 100,000 more people have moved to Seattle. More neighborhood branches, even small ones, would make the library’s collection and many services even more accessible. The system map shows potential expansion opportunities in Chinatown-International District and Belltown.
Public Parks
Public parks and open spaces are critical for supporting people living and working in dense urban environments. They help urbanites relax, exercise, socialize, and host public events. Great parks provide momentary respite from busy streets, chances to people watch, views to landmarks and the open sky, soothing trees and water, and places to sit, eat, and play.


Given the intensity of existing development this gap may not be closed without aggressive or creative efforts. The proliferation of privately-owned public spaces (POPS) might help in limited ways. These are typically small plazas built in exchange for taller skyscrapers. A few Downtown POPS are successful and invite public use, but for most the name belies their design. Many are hidden, poorly designed, inactive, or feel unwelcoming due to security presence. They cannot be counted towards the public parks goal.
Another approach is converting streets into parks, an increasingly popular tactic where options are limited. Famous examples include Times Square and the banks of the Seine. Locally the Pavement to Parks program has adapted streets in places like Rainier Vista, First Hill, and Capitol Hill, providing space for public events and passive use. On the other hand, pavement parks have minimal potential due to their paved surfaces and constrained size. There is not an obvious Downtown street to close completely to traffic and replace with family-friendly features like playgrounds, sportcourts, dog runs, or splashpads. Bell Street Park, a refreshing pedestrian experience, does not qualify as a usable park because it operates as a vehicular street at most times.
Calculation: After Waterfront Seattle is completed, the remaining Downtown parks deficit is estimated to be 17 acres. Considering the enormity of this amount, a reasonable goal is half that: 8.5 acres.
Minimum Public Land Demand: 12.4 Acres
Adding up the demand categories, the estimated demand for Downtown public land is 12.4 acres. This is a fairly substantial figure but it is simple to visualize: six to nine city blocks (depending on the block size) or about the area of Cal Anderson Park. Importantly, less land is needed if multiple uses can be combined on single sites. This is discussed after the next step of examining public land supply.Supply
This section sifts through the current inventory of public land and follows with acquisition contingencies. The analysis is more refined than an approach recently taken by the King County Assessor’s office, which published an indecipherable map of all government-owned parcels within Seattle city limits. Examining the situation on the ground furnishes a clearer picture.1A. Inventory of city-owned land
The primary interest is action that can be taken by the City of Seattle, so this step only identifies city-owned properties. There are a number of them developed in Downtown. The larger sites include the administrative and public safety campus, Benaroya Hall, the Central Library, and the waterfront aquarium and piers. Smaller properties include parks and SHA apartment buildings.
- A 0.5-acre Seattle City Light substation at Western and Union could be relocated fully underground with public uses above
- A 0.2-acre Seattle City Light parking lot in Belltown could be used for a small capital facility. However, it may already be planned to become part of a new park when the adjacent Alaskan Way Viaduct is demolished.

1B. Inventory of all public land
Many other governments own land in Downtown. Among them are King County, the state government, the federal government, the Port of Seattle, and the University of Washington.
- In front of the Nakamura Federal Courthouse is 0.6 acres of park-like open space that is almost virtually unused, directly across the street from the Central Library. Working within the security constraints of a federal facility, this site could be formalized and programmed as a central park that is more welcoming, usable, and accessible.
- A 0.6-acre King County parcel along 5th Avenue appears to be an unofficial park, but current conditions do not invite recreational use
- A wooded 0.6 acre King County site at 6th and Yesler sits between a private office building and I-5. It’s possible the site is being landbanked for future King County office space, an objective that is not necessarily exclusive of other public purposes. A moderate slope and proximity to loud, polluting freeway traffic would require design mitigation.
- Between King Street Station and the Weller Street pedestrian bridge is a 0.2-acre parcel owned by the King County Wastewater Division. It has sat empty and fenced off for years.
- A 0.6-acre Sound Transit parcel next to the Paramount Theater, which hosts a tunnel ventilation tube, could be re-purposed for a variety of uses
- The federal post office at 3rd and Union sits on about 0.7 acres. Though not historically landmarked, it is a sturdy 1959 concrete building and the airspace above it might be utilized like how the old Federal Reserve building is being expanded.
- A 0.15-acre state-owned parking lot in Belltown is next to a building leased by the Department of Social and Human Services




2A. Private vacant parcels and surface parking lots
As essentially blank slate sites with limited demolition required, these parcels are the most straightforward to purchase and develop. Surface lots are becoming rare as demand for office space and new homes create development pressures, but a number remain. Smaller lots are likely to survive longer because they are less efficient to develop, though that is balanced against their lower land value.
- A full-block, 0.8-acre parking lot on the waterfront at Western and Spring;
- 0.3-acre surface lot at the corner of Washington and Occidental;
- 0.2-acre parking area and a narrow 0.2 vacant lot on the waterfront at Alaskan and Yesler;
- 0.15-acre parking lot on 4th Avenue behind the King County administrative building;
- 0.3-acre parking lot across from Pike Place Market on 1st Avenue;
- 0.5-acre parking lot at 7th and Stewart;
- 0.5-acre surface lot at Western and Bell;
- 0.3-acre parking lot at 1st and Blanchard;
- 0.3-acre parking lot on 3rd near Blanchard; and
- A smattering of small surface lots near the Dexter Avenue/Denny Way/Aurora Avenue intersections.


2B. Private above-ground parking garages
The next easiest strategy for land acquisition is above-ground parking garages. Many are approaching or beyond the end of the typical 50-year lifespan and have endured decades of heavy wear and tear. Further, underground parking is now the norm, allowing cars to be tucked away out of sight and freeing the airspace above for people to live and work. These factors along with high-rise zoning, evolving transportation preferences, and an impending wave of autonomous vehicles makes above-ground garages tempting candidates to tear down for higher and better uses. Replacing unsightly and polluting parking with public uses, especially housing, is also a powerfully efficient way to meet the city’s goals for reduced carbon emissions. Puget Sound Regional Council parking data demonstrates many Downtown garages are not well utilized. Among surveyed facilities, in 2013 the average occupancy for the central business district was 65%. Since 2010 Downtown has added 45,000 jobs without adding nearly as many cars, indicating a shift towards transit, walking, bicycling, and taxi services. The map below illustrates where these structures are located. This inventory excludes most above-ground garages with other uses above (such as the 520 Pike Street building) and those integrally attached to the principle building (such as at the Warwick Hotel). The map also excludes garages that are already planned for demolition, such as two garages that will make way for 4/C, potentially Seattle’s next tallest tower at 100 stories.
- The Securities Building has a complex of structured garages above retail stores at 3rd and Virginia. The combined facility sits on 1.3 acres, opened in 1960, and has 520 parking spaces.
- The Swiftsure Garage sits on 0.5 acres at 2nd and Union and opened in 1969. It is nine floors with 509 parking spaces.
- A block away the West Edge Garage is on 0.3 acres at 2nd and Pike. It opened in 1963. It is seven floors with 335 parking spaces.
- The CPS Garage at 1st and Columbia was built in 1970. It sits on a 0.6-acre site and has nine floors with 509 parking spaces.
- The Elliot Parking Garage on Western and Vine opened in 1979 on 0.7 acres with five floors and 593 spaces.
- The Denny Building Parking Garage at Bell and 6th opened in 1968. It has 244 spaces on five floors and a 0.3 acre site.
- The Cherry Street Parking Garage at 3rd and Cherry was built in 1900. It is on a 0.2-acre site with five floors and 210 parking spaces.
- The Olympic Garage is on a 0.6-acre site at 5th and Spring and opened in 1964. It is nine floors with 640 parking spaces and a small retail store. With its large site and central location it could be a prime opportunity for a mixed-use school and housing development in partnership between the UW, the city, and Seattle Public Schools, an idea explored in a 2014 design studio.
- The Washington Garage at 3rd and University. It sits on a 0.3-acre site, opened in 1966, and has seven stories with 316 parking spaces.


2C. Private 1-5 story buildings
This option would be the last resort because it is the most difficult, expensive, and controversial. Unlike the steps above, here a deep dive is postponed due to the wide range of technical and political factors. If the public properties and private parking sites turn out to be nonviable then a more thorough analysis will take place. The primary consideration is sites with no redevelopment plans currently on file. Examples include:- The two-story Markham office building at 3rd and Blanchard, built in 1928, is on a 0.15-acre parcel;
- At 2nd and Clay is a one-story retail store on a 0.3-acre site;
- In Pioneer Square the three-story Zoltar Building and one-story Fulton Building, combine with a surface parking lot to make a half-block site;
- At 6th and Jackson the two-story Washington Federal building sits on a 0.3 acre-site; and
- At 2nd and Seneca the five-story Security Pacific office building is on a 0.3-acre site.


- The five-story Seneca Building was demolished in 2017 for the 38-story 2+U tower;
- The four-story Chromer Building and an parking lot at 2nd and Pine will be redeveloped with a 15-story office tower;
- The four-story Terminal Sales Building Annex and flanking parking lots are due to be demolished for a 17-story hotel;
- The three-story College Club of Seattle headquarters made way for the 37-floor Madison Centre office tower;
- The three-story Seattle Metropolitan Credit Union and 2-story Seattle Trust Court near City Hall are slated for replacement by a 28-story commercial tower;
- The three-story Fassio office building in Denny Triangle will be torn down for 44- and 16-story residential buildings;
- The two-story Rainier Square mall is being replaced with a 59-story mixed-use tower and a 12-story hotel;
- The one-story Bergman Luggage building is likely to be replaced with an apartment tower, though the facade may be preserved; and
- A pair of one-story commercial buildings on 5th Avenue in Belltown will be redeveloped with an 18-story hotel and apartment building.

The Long View
In summary, there are about four acres of public land that can be put to better use and many more private sites that could be acquired. With so many parking lots and aging parking garages ripe for demolition, the city should move quickly to further analyze the best sites and negotiate with the property owners for purchase. These options will not last forever, but in theory this combination can meet the demand outlined above. In practice, the city government is unlikely to have an appetite for purchasing new property. In fact the city is actively shedding its inventory as quickly as it can. Public sites that would otherwise be available for meeting crucial community needs are being sold off to private interests, including the full block next to City Hall and a police communications shop in Denny Triangle. In March, the City Council declined to hold on to the Battery Street Tunnel for three acres of adaptive reuse. Further afield, a South Lake Union megablock created from the Mercer Street construction is likely to be sold without any public uses on the site, and under community pressure the city only reluctantly backtracked on selling 29 acres of land in the Duwamish Valley. Seven substation sites in northwest Seattle are currently for sale. The Real Estate Services website provides a list of other recently sold properties. Bruce Katz, a Brookings Institution Centennial Scholar, touched on this when delivering the keynote address at the 2018 State of Downtown. He said, “In the United States, think what we do when the government realizes they own something. It’s usually in the middle of an annual deficit and they go, ‘Oh, we better sell it. Get the best price right now, and if the value [would have appreciated] over time, whatever.’ ” As The Urbanist further points out, the communications shop site and others like it could be leveraged more sustainably:Acquiring land is one of the biggest hurdles affordable housing providers must negotiate. Typically non-profit builders seek city subsides to finance their projects after they’ve secured a site, which is an increasingly competitive bidding process as the real estate boom continues and prime sites get rarer. Better leveraging land the public already owns offers a way out of this conundrum. In some cases, perhaps public land can be leased rather than sold to keep the valuable sites in public hands. Additionally, to exert more control and pick up the pace of affordable development, Seattle could take a direct role in building public housing rather than relying so heavily on non-profit developers. Councilmember Mosqueda indicated she’s open to the idea of Seattle Office of Housing directly building public housing again.As a community we should put short-term thinking behind us and move towards a more resilient utilization and acquisition strategy for public land. Seattle should invest in real estate, especially Downtown, to help support a more prosperous and healthy future for the entire city. In just one example a large enough site could support a mixed-use tower with a school or community center on the bottom floors and public housing affordable to teachers and baristas above. Some floors could even be leased office space (taking a cue from the UW), providing a revenue stream to support housing and capital facility improvements in neighborhoods in all corners of Seattle. The city must also be creative with mixed-use infrastructure. The large Denny Substation in South Lake Union might have been better located underground with housing above. Similarly, Fire Station 10 in Pioneer Square, covering a full city block only steps from City Hall, could potentially have a tower built above it with housing and other uses; if that proves infeasible today, fire stations typically last 40-50 years (the facility opened 2008). Over the long term the city can build multiple uses at fire stations, libraries, community centers, transit hubs, and other public facilities citywide.
Conclusion
It’s conceivable that within 10 to 20 years the Downtown Seattle skyline will be “finished” as private construction develops the few remaining available sites. However, with continuing growth there remains a number of absent public infrastructure services in the city’s core, including affordable housing, schools, community centers, and public open space. The urgent need for leadership and action is reinforced with every private groundbreaking. Unless steps are taken to purchase private parcels or ink ground lease deals with landowners, the opportunities to provide these critical land uses in our urban core will quickly slip by. Investing in land today will help build a more sustainable, resilient, affordable, and healthy Seattle tomorrow. This article is a cross-post from The Northwest Urbanist.
