New fire bureau policy could allow speed bumps on more commercial streets

For years, as Portland has looked for ways to calm auto traffic in commercial districts like N Denver Avenue, SE Stark Street or NE 28th Avenue, the biggest tool in its shed — the speed bump — has been off limits.

“PBOT and Fire are in the middle of a conversation about the city’s emergency response network.”
— Diane Dulken, PBOT spokeswoman

The reason: Portland Fire and Rescue says major streets need to be flat and smooth enough for emergency trucks to rush down them, when necessary, without losing critical time when responding to emergencies.

But a new Fire and Rescue policy in the early stages of discussion would soften this rule by designating some major streets as being of secondary importance to emergency response routes. City officials say this might allow speed bumps on some such streets. But it’s not clear whether the decision by the city’s fire chief could be completed in time to affect the design of one street where the option might matter most: 28th Avenue.

“PBOT and Fire are in the middle of a conversation about the city’s emergency response network,” Portland Bureau of Transportation spokeswoman Diane Dulken wrote in an email Thursday. “As for 28th Avenue – it is way too soon to tell if traffic calming would be an option for any portion of that street.”

Rich Newlands, project manager for the ongoing 20s Bikeway project, said Tuesday that he’d seen a map indicating that 28th between NE Sandy and SE Stark might be one of the streets that could be allowed to get speed bumps under a revised fire bureau policy. If the city were in fact able to add speed bumps on 28th and/or 26th, that’d be important because it’s a way to improve the street for biking somewhat without removing auto parking.

“Speed bumps alone… won’t make the route comfortable enough for the interested but concerned.”
— Carl Larson, BTA

A professional biking advocate who’s following the 20s Bikeway project said he didn’t think that adding speed bumps would be enough to make 28th truly welcoming to most Portlanders if they wanted to ride a bicycle there.

“Speed bumps alone (absent extreme woonerf-style traffic calming AND traffic diversion) won’t make the route comfortable enough for the interested but concerned,” Bicycle Transportation Alliance Advocate Carl Larson wrote Thursday. “It’ll only improve things for bolder users. That’s not in keeping with the city’s goals.”

If the city were to install a traffic diverter on 28th, forcing auto traffic to turn east or west at some point, Larson said that might reduce traffic volumes on 28th enough to make most people willing to ride on the street. But he said the city has resisted such a big change.

“I pushed for calming and diversion and was flat-out denied,” Larson said. “PBOT does not seem interested in changing the road’s functional designation.”


The city’s current plan for 28th, as well as for other two commercial districts along the 20s Bikeway, is a so-called “couplet” that would include buffered bike lanes in one direction along the corridor, green-backed sharrow markings in the other, and a nearby parallel neighborhood greenway for bikers who prefer not to use the shared lane.

One shared lane and one buffered bike lane is the city’s lead option for several stretches of the 20s Bikeway. But under current fire bureau policies, the city isn’t allowed to include speed bumps in either direction.

But the need to remove parking from 28th to make way for the buffered bike lane has some businesses and landlords worried that it’d make the district less convenient to visit, and some nearby residents worried that commercial parking would fill up neighborhood streets.

Even some bicycling advocates say traffic calming might actually be preferable to a one-direction bike lane. Kirk Paulsen, a professional traffic analyst and advocate for better biking who sits on the 20s Bikeway advisory committee, said that the combination of green-backed sharrows, slightly raised crosswalks and speed bumps might be enough to make most Portlanders feel comfortable biking on 28th.

“If all three of those treatments would be used in combination, I honestly believe that the street layout could be left with on-street parking on both sides AND attract a portion of the interested but concerned demographic of bike riders that is highly sought after,” Paulson wrote Thursday. “Personally, I’d be more in favor of that design that keeps the roadway symmetrical (to all users) and focuses most of its attention on calming traffic as opposed to fighting the political battle to remove parking on one side for a design that only works well in one direction. It’d be much easier for all users to know what is expected of them with that very simple but effective design of calming traffic.”

Dulken, the city spokeswoman, downplayed the importance of speed bumps to the city’s decision about the best design for 28th and other commercial districts along the 20s bikeway.

“Even if they would be an option on a portion of 28th, they would be a component in a larger street design and by themselves would not change the overall conversation of whether bike lanes belong on any portion of 28th,” Dulken said.

Larson, meanwhile, welcomed the fire bureau proposal and said it’d be “good news for other projects” if it comes together. Stay tuned — we’ll definitely be covering its progress.

    If traffic speeds can be brought down to a natural 10 mph (and I think they can with the right design, maybe even *without* speedbumps), then I’m with Kirk. A shared road can be comfortable for the interested but concerned.

      I think we’re saying the same thing. “A natural 10 mph” environment is wildly different and would take more than just speed bumps to achieve. I see it as the ideal outcome but it doesn’t appear to be in the cards, even with this policy change.

      Sharrows alone would probably improve MY experience on 28th — no question — but this isn’t about riders like me.

      If a low-volume, 10 mph street is off the table, though, and a pair of buffered lanes is politically impossible, the couplet is actually a great compromise — a big step in the right direction.

      If a 10mph street is an explicit goal, then you are going to have a hard time selling the public on your vision. I want to be on a street where I can ride faster than 10mph. Plenty of 10mph streets already do exist in Portland…we have 59 miles of unimproved streets in our neighborhoods.

    Is that what those slices in the speed bumps on NW Cornell are for? Emergency vehicles? I always assumed it was so bicycles could come down the hill at speed. That’s what I’ve used them for. :) Interesting that PBOT’s emphasis is on preserving vehicle speed in case there is a future emergency situation, rather than reducing speed the rest of the time and thus perhaps preventing an emergency in the first place.

        Lowering the speed does not necessarily mean that your house burns to the ground either. The question is what’s the tradeoff between the extra 2 to 3 minutes it takes for someone to get to the house versus how many fewer people are hit by a car that is driving too fast. There’s a direct correlation between average rate of speed and accident frequency.

    This is an important and often forgotten discussion to have internally in a City…We in Vancouver (WA) had this internal discussion back in 2000-1 and it was very important as it allowed us to add traffic calming to arterials that had once been “hands off”.

    There were two critical factors in adopting this policy change: (1) both public works and fire departments’ end goals were pubic safety/ injury prevention [in Vancouver <25% of all fire truck responses are for fires...as most of them were traffic related injuries] and (2) the adoption of speed cushions instead of speed humps was also critical (raised crosswalks were still allowed.)

    Plus the Fire Department leadership realized over time that slower streets with traffic calming allowed more drivers to effectively yield to their operators and by requiring a 5 minute response window be maintained they would be more able to protect stations from closure…you may need more smaller dispersed stations or substations to keep the response time window low.

        Pretty much all new commercial buildings, including housing with 3 or more units, are already required to have sprinklers. The residential code, which applies to houses with 1 or 2 units, doesn’t currently require sprinklers, at least in Oregon. I tried to find statistics, but I don’t think there are enough new single family homes / duplexes being built in Portland every year to make a measurable difference.

    PS. And perversely the addition of bike lanes and road diets along many major arterials also helped improve response times by giving yielding drivers more space to pull over in less time thus improving response times.

    “Speed bumps alone (absent extreme woonerf-style traffic calming AND traffic diversion) won’t make the route comfortable enough for the interested but concerned,”

    Uhmmm…my “interested but concerned” partner rides 28th. While it’s one of her least favorite places to ride in Sunnyside she is still willing to tackle it when we are in too much of a hurry to walk (always our first active transport choice).

    “It’ll only improve things for bolder users. That’s not in keeping with the city’s goals.”

    Jennifer Dill conducted research and reported numbers that contrasted starkly with the ones Geller pulled out of nowhere:

    Strong and Experienced (most are not fearless):6%
    Enthused and Confident: 9%
    Interested but concerned who are comfortable riding in a bike lane: ~28%!

    http://ppms.otrec.us/media/1343164608500f10c0b01a0.pdf

    I personally have argued for the buffered bike lane option but I would certainly take speed bumps, less severe traffic calming, and super sharrows over nothing and I think that at least 25% of portland would be willing to ride 28th.

        Cool, never said I disagreed with it. You can lower vehicular speeds by a multitude of methods. Its mainly just comedic how up in arms everyone got about the speed bumps or traffic calming aimed specifically at cyclists due to a failure to yield causing an unsafe environment for pedestrians but as long as it only affects the big bad car we who bike can go on in our way of feeling entitled instead of looking at the whole picture (or getting oh so bitter when called out on it) and holding similar standards of safety across the board.

    Has it ever occurred to the Fire Bureau, that the easiest way to speed up their response time, would be to cut motor traffic congestion in half?

    Perhaps by, say, oh, I don’t know! Traffic calming our streets, and making them more appealing to people walking, biking, and taking transit, so that motorists aren’t clogging up our arterials when the fire trucks need to get through?

    I know. What a crazy idea! Motor traffic backed up six blocks on Burnside doesn’t impede emergency response times at ALL I’m sure. But a two-inch high speed table – OH MY GOD. The victims will be dead before the truck reaches them because of THAT.

    At some point there was a discussion about adding (Cornell like) speed bumps with gaps to SW Vermont as part of making this into a bike route (PBOT just started working on the sidewalk and bikelane construction between 30th and 35th). In one of the first community meetings PBOT said that Vermont could be the second road in Portland to get the divided speed bumps that they tested on Cornell. So I wonder if that’s still discussed for Vermont. After all it’s a steep hill so it’s easy to go beyond the speed limit downhill.

    In my experience speed bumps are a poor solution for traffic calming…they don’t even work for the most aggressive drivers…once those clowns figure out they can run them at well above the legal speed without damaging their cars those speed bumps just become a fun obstacle course where they get to launch their car. Motorcyclists really love them I have noticed…great fun!

    In my unscientific assessment the only effective means of slowing ALL the cars is the implementation of roundabouts. Roundabouts also have the added benefit of reducing the severity of collisions at that intersection when they inevitably occur because instead of getting struck at 90 degrees broadside most collisions are angling sideswipes that are far less violent. The whole emergency response time is a red herring with regards to speed bumps anyhow…I live on N Alberta and the cops haul ass at 50+ mph over the speed bumps…no slower than they did before the bumps were installed. Roundabouts with through cuts for the emergency vehicles are the best long term traffic calming solution…but it will never happen do to the higher cost.

    Something that is never discussed about speed bumps is the jarring noise they generate…every delivery truck with a loose loading platform, every landscaper’s trailer, every low front spoiler, every creaky suspension…CRASH!, K-BOOM!, SCRAPE!, CREAK!…all day and night…it is VERY noticeable and unavoidably intrusive…for the first month after the bumps were installed I was rushing to the front door daily thinking there were cars crashing in front of my house!

      I used to live in front of a speed bump on a bikeway, also. You didn’t mention the inevitable screech of breaks and then roar of engine that typifies a car going over a speed bump (not to mention the extra puff of exhaust for any old car or diesel). Most cars do not try a steady slow speed over speed bumps, but rather race/brake for them.

        And one more thing, the Fire Dept (Engine 25) drove their water truck and ladder truck up and down this street all the time since their station house was a few blocks away on 52nd. Why did they go down this street with speed bumps, I never knew – since they had plenty of other streets on the grid to choose from. They went in both directions, both to (with lights/sirens) and from emergencies. PFD always used this street with speed bumps – by choice.

      You can’t build roundabouts at every intersection, if you actually mean a roundabout, and not a traffic circle. Traffic circles only affect speeds for about 100 ft on either side of the intersection, and cost between $5k and $20k. Modern roundabouts cost 100 times more. Speed bumps cost about $2500 each and can be placed anywhere along a street segment.

    Police cars are like fire trucks the same way walking is like biking. Police vehicles have lots of added extras so they can safely operate at high speeds. Fire trucks only started getting shocks in the last 10 years. The horsepower to weight ratio is significantly different as well. Thanks for at least alerting us that you’re unscientific.
