The Amazing Bollards of the Boston Fed

Bollards—those vertical posts used to keep cars off of bike trails or separate lanes of traffic—are also used to protect sensitive buildings from vehicular incursions. Many government buildings—and most of the city of Washington, D.C.—are surrounded by steel or concrete posts. In most cases, these are architectural afterthoughts, and in many cases they are ugly as sin. While they seem to crop up everywhere, their use, especially after incidents like the 1995 Oklahoma City bombing, is probably justified in some situations. They are relatively inexpensive, don’t impede pedestrian flow, and are quite effective (i.e. not just security theater).

And they don’t have to be ugly as sin.

Take, for example, the Boston Federal Reserve bank. Considering it is one of 12 banks in the country charged with distributing the nation’s cash supply, you probably don’t want people to be able to ram a car in to it. The modernist building is striking—it’s by far the tallest Federal Reserve Bank branch in the country and one of the tallest buildings in the city of Boston—so it has quite a bit of symbolic value. For a variety of reasons, you don’t want cars driving in willy-nilly. (If you do drive in, you go through a heated inspection building where they inspect your vehicle, including peering underneath with mirrors on sticks.)

Around the time of the Big Dig (check it out on HistoricAerials, or this picture from the installation firm) the plaza around the building was rebuilt, and instead of a bunch of concrete or aluminum-and-steel bollards, the landscape architects got creative. There are no fewer than 15 distinct types of bollard (!)—or other fencing with a similar function—combining different materials and serving multiple purposes. Many of these are cleverly camouflaged in to the landscape. You still get the idea that they don’t want you trying to ram through the doors in a car, but it’s not as ugly or overbearing as most such security.

I noticed this (yet again) coming back from a talk by Julie Campoli, who has cataloged housing types and walkability beautifully in presentations and books, and decided to do something similar with the Fed bollards. Here is a compendium, with descriptive names I made up.

Left: Steel-and-bench
Center: Single-indent concrete
Right: Double-indent concrete

Left: Slate-with-bench
Center: Wide steel
Right: Marble and stacked-slate

Left: Upside-down boat keel
Center: Square steel
Right: Big round planter

Left: Trapezoidal-ish steel
Center: Boat keel with bench
Right: Torpedo/candlepin bowling pins

Left: Beveled concrete with square holes
Center: Corners with benches
Right: Beveled concrete with extending benches

There would be a larger project here to walk (or bike) around the city and find all the different examples of anti-vehicle security. Maybe when it’s above 20 degrees.
Walking around the Fed, you get the idea that someone put some thought in to the landscape. It is a large and looming building (it’s tall and attractive, but it looms) but the plaza is built to a human scale without being monotonous and without losing its security purpose. There are a multitude of materials (granite, slate, concrete, aluminum, steel, brick, grass), shapes and sizes. Much of the plaza is functional. Benches provide a place to stop and sit. Trees provide shade. And it’s unobtrusive (unlike the horrible Tip O’Neill balls o’ concrete or the mid-sidewalk steel bollards down Atlantic Avenue at Rowes Wharf). Hopefully new buildings, when they need this type of security, will have some scrutiny as to how it is designed. This is a good example.
Now, there’s the argument that this site sacrifices a lot of density by having this big plaza, and despite the height of the building its floor-area ration (FAR) is not that high, only about 4:1! (In other words, if there was a four story building built across the whole site (which is what this building replaced) it would be denser, despite the fact that this is the third tallest building in the city! But at least the security outside is pleasant.
