Should Amazon.com build taller in Seattle?

Monday, March 12th, 2012
Do we want the Amazon buildings to look like the Russell Investments Center, the widest building on the Seattle skyline? Here is the Russell building times three. Photo montage by Scott Surdyke.

 

Scott Surdyke,  SeattleScape’s newest blogger, has some things to say about Amazon.com’s proposal to build a large office complex in downtown Seattle. Here is his take:

The news is REALLY BIG: Amazon and its architect, NBBJ, will present to the downtown Design Review Board on March 27th its proposal for a MASSIVE new office tower campus in the heart of the Denny Triangle. The proposal is expected  include up to three (3) 1-million-square-foot towers, and may include up to two towers per block. In ANY city today, this would be viewed as a once in a lifetime project, a signature addition to the skyline, and an equally important opportunity to provide great public benefits such as open space and other on-site amenities. However, the scale and potential bulk of these proposed towers is concerning when you consider just how big (wide) a million-square-foot building has to be when it only has 500 feet of height to work with.

A tale of Two Towers:

The widest building on the Seattle skyline is the Russell Investments Center (former Washington Mutual Tower). This is a 1.2 million SF building, also designed by NBBJ,  squeezed into 575 feet of height, and it is a full block wide. The size and shape of this building was determined by the former “CAP” on building heights, which were first reduced to 450’ in the late 1980s.  Since then, height limits for major towers have incrementally crept upward as Seattle has warmed up to the fact that taller, narrower buildings (think Vancouver BC) are much more desirable than squat, full block buildings, which tend to block out sunlight, create a “canyon” effect and offer little or no public open space.

A major contrast to the Russell Investments Center is the original Washington Mutual Tower, which at 772 feet is widely considered one of Seattle’s most beloved skyscrapers. That building, even though it’s approximately 200’ taller, is roughly the same size (1.1 Million square feet) as the Russell Investments Center, if not a little smaller. Not only  is the building, now called 1201 Third Avenue,  a striking and elegant addition to the Seattle skyline, but it also offers substantial public open space with its sunny and lushly landscaped plaza.

Today our city planners and leaders have thankfully embraced the blueprint for a truly sustainable and livable downtown, whereby taller, more slender towers are encouraged in order to provide greater public benefits such as open space, light and air between buildings. Vancouver, BC is an ideal model of how this can be achieved, and even that city has now raised its height limits in anticipation of buildings in the 600-700’ range. However, in order to achieve that height, new towers in that city are subject to more rigorous design review, and they are expected to meet greater architectural standards as well as increased open space and LEED requirements.

Similarly, heights in Seattle’s central downtown core have been lifted. However, the adjacent Denny Triangle, often considered a “secondary” office core, has height limits of only 500’. Perhaps there was an assumption that those million-square-foot tenants (of which there are very few) would likely go in a single tall (or is that double-tall?) tower in the central downtown core.  Such is not the case for the Amazon proposal, where the preferred location of its new towers is appropriately much closer to its new campus in South Lake Union.  Planners at the time likely did not conceive that there would someday be demand from a single user for 3 million square feet in a neighborhood that is largely known for vacant lots and  car dealerships. This, then, may be one of those instances where it makes much more sense to consider allowing buildings with a taller, leaner profile.  As Seattle gets denser, we will have precious fewer opportunities to for light, air, open space and the views that are cherished by so many. It would be prudent for Amazon and our city leaders to at least consider an option that allows for a taller tower configuration (much like the way the City already accommodated Vulcan and Amazon by raising height limits for several of its South Lake Union buildings). Rather than three or more towers of 500’ each,  a tower campus with a true variety of heights might achieve greater long-term benefits for our city.

Before the City accepts a proposal that could equate to the combined mass of three Russell Investments Centers (see above),  we should at least give Amazon and NBBJ the opportunity to consider narrower, taller buildings for its new tower campus.  The current density would not have to be increased, however allowing flexibility for taller and narrower buildings could bring more open space and provide other public benefits to our “new” downtown.

According to the city of Seattle, a public meeting will be held Tuesday, March 13 at 6:00-7:30 p.m. at Seattle Municipal Tower, Room 4050 to identify concerns about the site and to receive public input into establishing priorities for public benefits which may include low income housing, townhouse development, historic preservation, public open space, implementation of adopted neighborhood plans, improvements to pedestrian circulation, urban form, transit facilities and, or other elements that further an adopted city policy and provide a demonstrable public benefit.

A copy of the proposal materials are available at the DPD Public Resource Center, 700 5th Avenue,  Suite 2000. The center is open 8 a.m. to 4 p.m. on Monday, Wednesday, Friday and 10:30 a.m. to 4 p.m. on Tuesday and Thursday. The telephone number is (206) 684-8467.

City to remove Madison Park fence

Tuesday, December 20th, 2011

The city of Seattle will remove a fence in the Madison Park neighborhood that for decades has blocked public access to a block-long swatch of Lake Washington shoreline, one block north of Madison Beach park.
The decision by Acting Seattle Parks Superintendent Christopher Williams follows a campaign by Patrick Doherty in SeattleScape to get that area opened to the public.
Removal of the fence was opposed by some Madison Park residents who cited safety concerns.
The city expects to start taking down the fence in early 2012, Williams said on Seattle.gov.
He said that all the 20-plus miles of city-owned shoreline along Lake Washington and Puget Sound and associated tributaries is accessible to the public except that stretch.
The fence was installed in the mid-1940s.

This block-long stretch on Lake Washington has been behind a fence for decades.

Popular Mechanics has the inside story on how exactly crews will replace the 48-year-old  state Route 520 floating bridge across Lake Washington with a new six-lane bridge. If you’re wondering how they will get a quarter-million tons of concrete to float, this story tells you.

Trees and vines are taking over the ghost tower

Just fourteen years ago, the Sathorn Unique skyscraper in Bangkok, Thailand was being built as one of the city’s fanciest residential addresses,  according to abandonedjourney.com, which chronicles abandoned buildings. Never completed, it is yet another “ghost tower,” notes the site, which says trees and vines are beginning to take over the  four story archways and romanesque feature columns. It was built during the mid nineties, when the Thai economy was booming. In 1997, the Asian Financial Crisis changed all that. Developers stricken with debt were unable to finish many projects, the site notes. In the case of Sathorn Unique, the main concrete structure made it all the way to the top. The apartment fit-outs had begun in earnest, with wooden floor boards installed and polished. Connected bathtubs, wardrobes, and electrics show just how close this one was to completion. At ground floor, two escalators have been installed, climbing to nowhere in particular, the remnants of protective plastic still clinging onto their stainless steel sides.  With an amazing location close to the Chao Praya river that snakes its way through the center of Bangkok, it’s easy to see how this abandoned building would have been luxury living at its finest, the website says.

Steven Holl pushes edge of design in China

Tuesday, July 5th, 2011

 

A New York Times article looks at a new design in China by Bremerton-born architect Steven Holl. The Vanke Center on the edge of the city of Shenzhen is a surreal hybrid — part building, part landscape, part infrastructure, according to the Times, which notes that in China Holl has the freedom and means to bring to life some of his most potent urban ideas.  The Vanke Center shows what can happen when talented architects are allowed to practice their craft uninhibited by creative restrictions (or, to be fair, by the high labor costs of most developed societies), the Times notes. Steven Holl Architects, with offices in New York City and Beijing, has been recognized with some of architecture’s most prestigious awards and prizes. In July 2001, Time Magazine named Holl as America’s Best Architect, for ‘buildings that satisfy the spirit as well as the eye.’ Locally, Holl, a University of Washington graduate, designed the Chapel of St. Ignatius for Seattle University.

Magazine: Amanda Burden works to reclaim NYC’s waterfront

Tuesday, June 28th, 2011

WSJ Magazine, a publication of the Wall Street Journal, has an interesting article about Amanda Burden, daughter of well-known socialite Babe Paley and director of city planning for New York. The magazine says she is spearheading Mayor Michael Bloomberg’s effort to rezone nearly a quarter of New York City and reclaim the city’s waterfront. Her populist achievements include zoning for new affordable housing in East Harlem, Brookyln and the South Bronx, as well as the massively popular High Line, an abandoned railroad track that has been transformed into a popular tourist destination in the meatpacking neighborhood.

Time to add more options at light rail stations?

Monday, June 20th, 2011

Local news sites/blogs Seattle’s Land Use Code, Publicola and Citytank have been having an ongoing discussion about plans for an upzone in the Roosevelt neighborhood of Seattle. Those commenting have argued over how much density is needed near the light rail station planned for Roosevelt. But — as at least one of those commenting pointed out — how about the stations themselves: Why aren’t more useful things offered at transit hubs? As DJC contributor Clair Enlow noted, the stations could be mobility hubs, where commuters could grab a pre-reserved bike or park one, line up a taxi for the other end of the ride or pick up pre-delivered groceries on the way back. It’s a kind of multi-modal switching platform, where transportation meets information technology, and people can connect with essential goods and services, she writes. What do you think? Could we be doing more with the stations and the parking lots surrounding them?

This rendering provided by Cascadia Center for Regional Development shows a concept for a transit hub at the South Transit Park and Ride. It accommodates shared vehicles and places for pickup of pre-ordered goods. Passengers can transfer from rail to bus and find retail shops. King County Metro's plans to redevelop the park and ride do not include commuter rail. The site is along 108th Avenue Northeast, west of Interstate 405 and north of state Route 520.

It’s back

Four years ago, some of us were reminded (again) that the greater Downtown Seattle housing boom isn’t a birthright. Even with apartments and condos somewhat countercyclical, the whole shebang can slow dramatically, or even stop. But wow, if you love to see Seattle growing and filling in, the fun times are back.

From Lower Queen Anne to Broadway to the far side of First Hill and the CBD, something like 2,300 housing units are under construction right now, many of which I walked by in a big loop today, confirming actual starts vs. mere fence and site prep. That’s less than half the peak volume for that area, but a very healthy number, particularly since most started in a short period. More than 2006, these homes tend to be for the middle income ranges.

A couple thousand units isn’t a massive addition for that area in the scheme of things, with around 60,000 residents already here. But it’s part of greater Downtown’s march toward the real citydom. Slowly more neighborhoods have active sidewalks. Some gaps in our smile (parking lots) are getting fixed.

“Real citydom” is a concept whose meaning and desirability are very personal and subjective. For example, some argue, perhaps rightly, that the “real” part takes a decade or two at least, so that the neighborhood and building have had time to grow and adapt beyond their original states. Or maybe it’s about how much varied stuff is within walking distance, preferably including some good takeout pizza. On the flip side, some people prefer surface parking, and “city” is a bad thing. My bias isn’t a simple as “more is better,” but that’s a good start.

The Terrazza “apodment” project on 11th by Seattle U is very impressive, and one of the starts confirmed today. Per a recent DJC article, the 56 units will average 180 square feet, and there will be no elevator or parking. This is a crucial piece of Seattle’s affordability puzzle. While these homes aren’t for everyone, here’s a way people can live in a central neighborhood without subsidy at a low cost. This lets us focus levy funds et al where they’re really needed. Seattle keeps a few more of our bohemians or low-wage workers, a crucial aspect of any city’s success.

On the same walk, it was also fun to see tourist season in full swing. No, seriously! It’s fun for one’s city to be a host, even when people walk slowly four abreast. It’s sort of like being complimented. The waterfront was full of people all the way to the Sculpture Park, even with this week’s new crop of cruise passengers mostly loaded already. At the park, with the temperature pushing 70, several of the loungers clung to tiny havens of shade, apparently moving every 15 minutes…

Another topic for another day: While greater Downtown is growing housing at a good clip, the region isn’t. Does this suggest a low risk of overbuilding?

What kind of development will Seattle get post-viaduct?

Thursday, June 9th, 2011

A New York Times article says that preserving the High Line viaduct in New York as a public park revitalized that

area and generated $2 billion in private investment. The story quotes Mayor Michael R. Bloomberg as saying

that the deluxe apartment buildings and hundreds of art galleries, restaurants and boutiques near the High Line make up for the $115 million the city has spent on the park and the deals it has made to encourage developers to build along the High Line without blocking out the sun.

Do you see any parallels with the High Line and plans for the Alaskan Way Viaduct in Seattle and Seattle’s Central Waterfront?
