Pre-Fall – Select menu items from the Sept 17, 2018 Cambridge City Council Agenda

City HallThe boys and girls return to the playground this week. Here are a few things that caught my eye.

Manager’s Agenda #1. A communication transmitted from Louis A. DePasquale, City Manager, relative to recommendations of the Community Preservation Act Committee (CPAC) for FY2019.

80% housing, 10% open space, 10% historic preservation – same as every year. Not negotiable.

Manager’s Agenda #4. A communication transmitted from Louis A. DePasquale, City Manager, relative to a recommended appointment of the following person as a member of the Cambridge Housing Authority for a term of 5 years: Elaine DeRosa

I cannot think of a better choice for this important appointment.

Committee Report #3. A communication was received from Paula Crane, Deputy City Clerk, transmitting a report from Councillor Sumbul Siddiqui, Chair of the Economic Development and University Relations Committee, for a public hearing held on Wed, June 20, 2019 to discuss the potential for a City-based Cannabis Social Equity Program, focusing on ways to reduce barriers to entry in the commercial Cannabis industry.

Manager’s Agenda #6. A communication transmitted from Louis A. DePasquale, City Manager, relative to a Planning Board recommendation to adopt the Cannabis Zoning Petition with suggested revisions and additional considerations.

I’m a little curious about this: "Board members suggested further study of whether mobile facilities could be allowed, given that a mobile facility operating on a temporary basis might provide lower barriers to entry for small businesses that cannot afford typical retail rents." Are they talking about pot trucks to go along with the food trucks? When I was a kid there was a Good Humor Man who got caught selling dope out of his ice cream truck. Nowadays they’d just call that economic empowerment.

Manager’s Agenda #8. A communication transmitted from Louis A. DePasquale, City Manager, relative to the reappointment of the following persons as a members of the Library Board of Trustees: Karen Kosko, Patricia Payne and Nancy Woods.

Excellent appointments all around.

Applications & Petitions #3. An application was received from the Office of the Mayor McGovern requesting permission for a temporary banner across Massachusetts Avenue in front of City Hall promoting the Indigenous Peoples’ Day from Oct 3, 2018 thru Oct 15, 2018.

Most people just celebrate this as Day Off. No banner necessary.

Resolution #3. Resolution on the death of Frances (DeGuglielmo) Tingle.   Councillor Simmons, Councillor Toomey

Resolution #6. Retirement of Attorney David Sullivan from the Massachusetts State Senate.   Mayor McGovern

Resolution #29. Retirement of William"Bill" Dwyer from the Department of Public Works.   Mayor McGovern

One thing not everyone knows is that the Department of Public Works is a community with many people who work for decades, sometimes their entire working life, within DPW. Retirements of people like Bill Dwyer are a very big deal indeed.

Order #1. That the City Manager is requested to work with the Community Development Department to establish a Senior Living Overlay District at the current site of Sancta Maria Nursing Facility to encourage and incentivize redevelopment specifically for continuum of care services.   Councillor Mallon

I think we’re starting to get a bit too prescriptive with Cambridge zoning, especially with the introduction of "overlay districts" for every imaginable use. Many of us would like to see opportunities for senior living or a place where artists can flourish. We would also like places to buy affordable groceries. Is the creation of an overlay district to dictate one use while preventing other potential good uses the right way to go? It’s one thing to classify land use as residential, commercial, industrial, etc., but how far down should this categorization go?

Order #3. That the City Manager is requested to confer with the appropriate City departments and relevant housing partners to aggressively attempt to obtain, or help others obtain, the Santa Maria property for purposes of affordable housing.   Councillor Kelley, Councillor Toomey, Mayor McGovern

Whatever happened to the idea of a relocated Public Works Yard? I’m not necessarily recommending this, but putting DPW on Concord Ave. and building mixed-income housing on the current DPW site isn’t a crazy idea.

Order #4. That the City Manager is requested to work with the Police Commissioner to increase enforcement of the Bike Lane Bill to keep our bicycle infrastructure free and unobstructed.   Mayor McGovern, Vice Mayor Devereux, Councillor Zondervan

Does this apply to Really Bad Bicycle Infrastructure (RBBI)?

Order #7. That the City Manager is requested to report back to the City Council on the tax status, zoning history, and sale of The Constellation Center’s Parcel C in Kendall Square.   Councillor Kelley, Councillor Toomey

Anyone who has followed this knew this Order would eventually come. That will be an interesting and likely fruitless journey down the road of Retroactive Zoning & Tax Classification. Looking forward would make a lot more sense, but I’m sure I’ll find the history interesting.

Order #12. That the City Manager is requested to work with the Economic Development Division to regularly update the vacant property database as well as review the strategies presented in the Storefront Vacancies Best Practices Report and report back on the feasibility of implementing these recommendations.   Councillor Siddiqui, Councillor Mallon, Councillor Zondervan, Councillor Carlone

I testified recently at a follow-up meeting of this committee about the potential unintended consequences of encouraging "pop up" businesses to occupy vacant spaces at (presumably) much lower rents than nearby businesses. I can easily see a seasonable "pop up" store showing up and stealing all the holiday business away from an existing business. The temporary filling of a vacant store could then lead to another vacancy.

Order #13. That the City Manager is requested to direct the City Solicitor to provide a legal opinion on a Motion to Rescind.   Councillor Zondervan

Order #14. That the City Council rescind its vote of July 30, 2018 failing to send the climate safety (Brown, et al) petition to a second reading, thereby taking no action on the petition.   Councillor Zondervan

Our petulant Councillor Zondervan continues to stomp his feet in protest over the failure of the Nakagawa-Brown petition to be passed to a 2nd Reading. First he tried to file reconsideration, and now he wants to go for the legislative equivalent of annulment. I am not a lawyer (IANAL) and I have no prior knowledge of anyone ever looking to do pull a "Motion to Rescind" on a prior vote, but consider the ramifications of such a thing. A local legislature votes on a zoning matter (one way or another) and the matter is finalized. A property owner then happily goes to the bank to secure financing now that the road has been cleared. Then a month or so later the local legislature comes back and cries "Do Over" like that annoying kid who didn’t like the fact that the other kids prevailed in the ball game.

Committee Report #5. A communication was received from Donna P. Lopez, City Clerk, transmitting a report from Councillor Dennis J. Carlone and Councillor Craig A. Kelley, Co-Chairs of the Ordinance Committee, for a public hearing held on Aug 13, 2018 to discuss revisions to the proposed Municipal Code amendment to create a new chapter 12.22 entitled “Surveillance Technology Ordinance;” said revisions were submitted to the City Council on June 25, 2018.

The interesting aspect of this (at least to me) is the legal separation of authority under the City Charter. The City Council may be the body that sets general policies, but can you imagine the ensuing chaos of having the Cambridge City Council micromanaging how the Cambridge Police Department conducts its day-to-day operations or how it responds to an emergency situation? It’s one thing to set parameters and maintain a dialogue, but police investigations should not be arbitrarily constrained by people trained more in politics than in police work.

Committee Report #6. A communication was received from Donna P. Lopez, City Clerk, transmitting a report from Councillor Dennis J. Carlone and Councillor Craig A. Kelley, Co-Chairs of the Ordinance Committee, for a public hearing held on July 23, 2018 to discuss a proposed amendment to the Municipal Code in Chapter 10.17 entitled “Vehicle Trip Reduction Ordinance” in section 10.17.070 entitled “Fees for Residential Parking Stickers.”

I attended this meeting. My impression is that we have several elected officials who have never seen a fee increase or a tax increase that they didn’t embrace and celebrate. The simplest way to understand fees is to make clear the distinction with taxes. A fee pays for a service, and the money raised has to support that service. It’s not just another revenue source like a tax that can be used for whatever pet project a councillor wants to support. Personally, I find the notion of renewing a parking sticker every year a bit ridiculous. We accept it only because we’re familiar with the routine (and the long lines for some). A much better system would be to pay a one-time fee for a sticker that’s good for as long as you own the vehicle and still live in Cambridge. It would be easy to encode the sticker for easy verification against City databases. The only people waiting on lines would then be for new residents or new vehicles.

Committee Report #8. A communication was received from Donna P. Lopez, City Clerk, transmitting a report from Councillor Dennis J. Carlone and Councillor Craig A. Kelley, Co-Chairs of the Ordinance Committee, for a public hearing held on Aug 8, 2018 to discuss City Council petition to amend the Zoning Ordinance in Article 5.000 as it relates to rainwater and flat roofs.

As an owner of a triple-decker with a flat roof, I completely understand the concerns about clogged drains and why someone might seek an alternative design. The ideas in this zoning petition have merit. The only issue should be how to ensure that one person’s cure is not another person’s cause of trouble, i.e. rainwater being diverted to an unwelcome place. – Robert Winters

Cambridge at cross purposes about traffic

Readers of the newsletter of the Belmont Citizens Forum will find much news there about neighboring North Cambridge. Editor Meg Muckenhoupt’s lead story in the September-October 2013 issue is about major, new housing developments planned for the part of Cambridge west of Alewife Brook Parkway and north of Fresh Pond Park. The article expresses concerns with traffic which is already approaching gridlock and affecting access to the Alewife T station.

Quoting from the story:

The decision document issued by Cambridge’s Planning Board for the 398-unit 160 Cambridgepark Drive, which is predicted to cause 1,324 new trips, states, “The project is expected to have minimal impact on traffic and will not cause congestion, hazard, or substantial change to the established neighborhood character.” Ominously, the decision continues: “It is also noted that the traffic generated by the project is anticipated to be less than that associated with the office/research and development project on 150, 180 and 180R Cambridgepark Drive for which entitlements currently exist under a previously granted special permit.” In short, if the city of Cambridge accepted a potential increase in traffic for a special permit in the past, the city should accept that increase in traffic for all future permits—no matter how much the population has increased in the meantime.

[…]

Concord Avenue and the Alewife Brook Parkway rotary won’t escape traffic woes. Cambridge’s 2005 Concord Alewife Plan included a “critical movement analysis” of the area. Critical movements are conflicting traffic movements. They are the times when vehicles block each other from moving, such as when a car turns left and crosses a lane of oncoming traffic. The Concord Alewife Plan reports that for the area roughly bounded by the Route 2/Route 16 intersection, the Alewife Brook Parkway, and Concord Avenue, service starts to deteriorate when a roadway reaches the “critical sum” of 1,500 vehicles per hour, or 1,800 vehicles per hour for rotaries. Below those numbers, and most motorists can get through an intersection in two or fewer light cycles. Above those thresholds, you’ll wait at that light a long time. As of 2005, the Concord/Route 2 rotary was already operating at 1,880 critical interactions—80 above the threshold—with a total traffic volume of 4,300 trips per day, while Concord Avenue at Blanchard Road had already reached 1,400 “critical sums” per hour, with 2,460 trips per day.

The report also predicted vehicle trips per day for 2024 for the area after Cambridge’s rezoning (which Cambridge enacted in June 2006.) The permitted 70 Fawcett Street development, which will be located between these two intersections, by itself promises to add enough vehicle trips to reach the predicted 2024 buildout trip level by 2014—and there’s plenty more space for apartments and garages alongside between the Concord Avenue rotary and Blanchard Road.

Also:

Of course, some of these buildings’ residents will take the T to work—if they can fit on the T…The Red Line is already “congested” and running at capacity, according to a June 2012 study by the Urban Land Institute titled Hub and Spoke: Core Transit Congestion and the Future of Transit and Development in Greater Boston.

So, Cambridge publishes a plan for the Alewife area which reports that traffic congestion is already a problem, but then it permits several large housing developments which will worsen it. The Belmont Citizens Forum article does report that design study has been funded for a new bridge over the commuter rail tracks west of Alewife Station, connecting it with Concord Avenue. That will relieve some congestion near the Alewife Brook Parkway/Concord Avenue rotary but will have little effect elsewhere. And this is still only a design study.

As a bicycling advocate and repeated critic of Cambridge’s treatment on Concord Avenue — see summary of my comments here — I have found another major inconsistency with the 2005 Concord-Alewife Plan: the recent reconstruction of Concord Avenue so as to maximize the number of conflicts between bicyclists and motorists. The new traffic signal just west of the Concord Avenue/Alewife Brook Parkway rotary backs up traffic into the rotary whenever a bicyclist or pedestrian actuates the signal to cross. The westbound sidewalk bikeway installed on the north side of Concord Avenue crosses a driveway or street on average once every 100 feet, requiring motorists to stop in the only westbound travel lane, blocking traffic, to yield to bicyclists overtaking on their right. Buses traveling both ways on Concord Avenue must stop in the travel lane, where their doors open directly into the bikeway. The conflicting turn movements between motorists and bicyclists, and bus passengers discharged onto the the bikeway, pose serious safety concerns too.

In previous posts on this blog and elsewhere, I recommended a two-way bikeway on the south side of Concord Avenue next to Fresh Pond Park, where there is only one signalized intersection, and maintenance of the previous roadway width and bike lanes.

The 2005 Concord-Alewife Plan contains no mention of the Concord Avenue bikeway — see recommendations for Concord Avenue on page 80 of the report. The plan therefore does not account for the congestion caused by the bikeway, on which construction began only 4 years later.

The overall impression I get is that Cambridge’s planning is disorganized, but also, Cambridge’s bicycle planning occurs in a fantasyland where the well-known conflict situations which cause crashes are greeted with a claim that the goal is to make bicycling more attractive, then, poof, when there are more bicyclists, by magic, bicycling will become safer. I call this the “Pied Piper” approach to bicycle planning. Well, actually, Cambridge is reporting a steady level of bicycle crashes in spite of an increasing volume of bicycle traffic. Some decrease in risk with increasing volume occurs with any mode of transportation as its users gain longer experience. The issue I have is with using this as an excuse for wishful thinking and crap design, and writing off the victims of preventable crashes as expendable. Cambridge has had some gruesome preventable crashes, and has intersections with the highest volumes of bicycle crashes anywhere in Massachusetts.

Another overall impression which I can’t shake is that Cambridge is very selective about reducing traffic congestion. The Concord Avenue project; the residential developments planned for the Alewife area; the Western Avenue roadway narrowing and sidewalk bikeway; and the proposed bikeways along Binney Street increase congestion at the portals to the city. It all strikes me as rather desperate and underhanded way to decrease congestion in the core of the city, but there you have it, as it appears to me.

[Added paragraphs, October 7, 7:40 AM] Residential development close to the urban core is certainly preferable to sprawling suburbs to minimize environmental impacts and traffic congestion, but resolving the traffic problems in the Alewife area would require major investments to increase Red Line and bus service, and disincentives (read: high cost) for single-occupant motor vehicle travel. The public resists all of these. If there is a logic to the City’s approach to these challenges, it is to break down resistance by making the problems so pressing that the pain becomes intolerable.

Bicycling and walking can make some contribution, but the plans for the new housing developments describe it as small. Quoting again:

To be fair, the developers of these various projects are attempting to make car-free commuting more attractive to their residents. Several of these buildings have extensive bicycle-parking facilities, including the Faces site and 160 Cambridgepark Drive. But the city of Cambridge doesn’t anticipate that those bicycles will get much use. For 398-unit 160 Cambridgepark Drive, for example, the city estimates the residents will make 1,324 daily car trips, and 202 pedestrian trips, but just 98 journeys by bike.

Most of the traffic in the area in any case is to or from more distant locations, or is passing through. Bicycling and walking may serve as feeder modes for these longer trips but don’t compete well with motorized modes to cover the distance.

Enjoying? the Concord Avenue “raised bike lanes”

The Cambridge City Council meeting on December 3, 2012 is to address issues of debris on the Concord Avenue “raised bike lanes”. These replaced conventional bike lanes at street level. I put the term “raised bike lanes” in quotes because a bikeway behind a curb is not a bike lane. By definition, a lane is at street level, so it is possible to merge to and from other lanes. Rather, this is a nonstandard bicycle path.

This post supplements comments which I posted on my own blog before Concord Avenue was reconstructed. The photos here are stills from video shot during a ride westbound at mid-day on November 20, 2012, with moderate motor traffic and very light bicycle traffic.

First photo: Crosswalk just west of the Alewife Brook Parkway rotary is backing up motor traffic. This already generates traffic jams with light bicycle traffic. The City expects the bikeways to attract more cyclists and to lead to a major increase in bicycle traffic.

Next photo: The westbound bikeway crosses 8 streets and 24 driveways in 3000 feet. The most persistent hazard on the westbound bikeway is of “right hook” and “left cross” collisions. The van in the photo not only is turning across the bikeway; it also might be hiding another vehicle preparing a left turn from ahead. The bikeway places bicyclists where they are defenseless against these threats. I say more about them, and how to avoid them, in my earlier blog post.

Next — bus stop. When the bike lanes were at street level, bicyclists could pass a stopped bus on the left, or wait behind it. Motorists also usually could pass a stopped bus. Passing would have been even easier with bus turnouts on the westbound side, where there is only one travel lane. Now that the roadway has instead been narrowed, converting the conventional bike lanes into “raised bike lanes”, buses must completely block the travel lane, and passengers getting off a bus step down directly into the path of bicyclists. A 2007 research study in Copenhagen showed an increase in bicyclist-pedestrian collisions of 17 times, and of injuries of 19 times, when bus stops were placed outside bikeways like this. More about that study.

That study was published well before construction on the Concord Avenue bikeway began. Not only that, the City’s bicycle coordinator repeatedly points to Copenhagen as a model of what Cambridge should do.

To resolve conflicts between bicyclists and passengers descending from buses, the City first painted bicycle markings. Those markings, however, suggest that bicyclists have priority, and these markings also may not be directly in front of a bus’s door when it opens, to warn the passengers. At some later time, green carpet painting was added. This is normally used to indicate where motorists yield to bicyclists (see Federal Highway Administration interim approval), but here it is intended to indicate where bicyclists must yield to pedestrians, a confused and contradictory message. This bus stop is at a driveway. Traffic has worn away some of the green paint and you can see the bicycle marking which was painted over.

One problem to be discussed at the City Council meeting is that snow clearance is not practical on the westbound bikeway, because of its repeated ups and downs. Ice also puddles there. Here’s a photo from another blogger, dr2chase, showing winter conditions on the westbound bikeway. dr2chase’s blog has many more photos.

dr2chase's photo of winter conditions on the Concord Avenue bikeway westbound

dr2chase’s photo of winter conditions on the Concord Avenue bikeway westbound

dr2chase also has made the point that snow clearance is much more practical on the eastbound bikeway, which has only one driveway entrance in its entire length. Here is his photo illustrating that:

drchase's photo of the eastbound bikeway in winter

drchase’s photo of the eastbound bikeway in winter

The bikeway on each side is designated as one-way. People are likely to use both of them for two-way travel, and not only in snow season, because a cyclist must stand in the street to lift the bicycle over the curb of the eastbound bikeway at most locations. Also note the seam between asphalt and concrete running down the middle of the photo above. It is intended to separate bicyclists from pedestrians. It won’t, especially with two-way bicycling, and over the years, it will deteriorate so it traps bicycle wheels. dr2chase and I have both made the point that a properly-designed, designated two-way bikeway on the south side of Concord Avenue, adjacent to Fresh Pond Park, would have made good sense, connecting with the existing bikeways in the park and crossing only one driveway in its entire length — at a signalized intersection. I also would have liked to keep the street at its previous width, with street-level bike lanes, to allow efficient through travel and make it possible to reach the eastbound bikeway without lifting a bicycle over a curb.

The next photo illustrates the crossing-the-street issue. Note the driveway at the right rear, and that there is no break in the curb on the far side of Concord Avenue. To cross without stopping in the street, and to avoid having to double back, cyclists will most likely ride eastbound in the westbound bikeway. That is illegal and hazardous: motorists pulling out of side streets and driveways look in the opposite direction for traffic.

The mailbox adjacent to the 5-foot-wide bikeway adds a nice touch as well. Nick it with your handlebar, and you go down hard. Even without such obstructions, 5 feet is minimal for one-way travel. This mailbox is one of a large number of fixed-object hazards adjacent to the bikeway.

Mailbox, and curb on far side of Concord Avenue

Not all hazards are fixed-object hazards. There are these trash barrels.

Behind the trash barrels, you may have noticed a car discharging passengers. A cyclist who regularly rides Concord Avenue reports that delivery vehicles also now stop in the bikeway.

My next photos show what I call the X-merge, or double-cross merge.

Normal traffic law requires a driver to maintain a constant lane position when another driver is overtaking. Here’s an excerpt from the Massachusetts law:

Except as herein otherwise provided, the driver of a vehicle passing another vehicle traveling in the same direction shall drive a safe distance to the left of such other vehicle and shall not return to the right until safely clear of the overtaken vehicle; and, if the way is of sufficient width for the two vehicles to pass, the driver of the leading one shall not unnecessarily obstruct the other.

Bicyclists may overtake on the right, according to another section of the law:

…the bicycle operator may keep to the right when passing a motor vehicle which is moving in the travel lane of the way…

When a bicyclist is directed to merge from right to left at an arbitrary location, and a motorist to merge from left to right at the same location, they are both violating the law. Green paint here is used to direct cyclists and motorists to operate illegally.

X-merge on Concord Avenue

I avoided right-hook threats by merging in behind the stopped car so the next vehicle turning right could safely pass me on the right.

Before Blanchard Road, a traffic island narrows the roadway. The bike lane, between the through travel lane and right turn lane, is too narrow to allow safe clearance on both sides. Note in the photo below that the narrow median on the far side of Blanchard Road allows much more room to the left of the bike lane. The traffic island predates the reconstruction: the bike lane has been shoehorned in by narrowing the other lanes. Concord Avenue is wide enough to accommodate turning traffic without the island’s being so wide.

Wide traffic island at Blanchard Road narrows bike lane on Concord Avenue

Well, enough. You get the idea. I’ll finish with a couple of quotes. Here’s one from MarkS, commenting on dr2chase’s blog post:

I don’t know why they wasted the time and money to put these tracks in in the first place. I find a bike lane much more convenient, and in some ways safer — clearly safer than that abomination on the north side of Concord Ave — the “outgoing” side. And, if ever we decide to re-design the situation, the expense of doing so will be significantly — and that’s an understatement — more than it would be to just re-paint the lines where the bike lane would have been.

Here’s another quote, from dr2chase:

…the west-bound side is about the most ineffective botch I have ever seen. But the eastbound side is quite nice (with the exception of the scary-high curbs). One extremely-low-traffic intersection, no driveways, hence none of those risks, and so wide that (with current bike/ped traffic levels) there is little harm in riding the wrong way on the good side. Technically illegal, but vastly safer, and I cannot fault someone for making the safer choice.

I agree! And have a look at the video online!

Concord Avenue, Under Construction

I just rode Concord Avenue last Sunday to see what was happening there.

I had thought that the construction project would have been completed by now, but it isn’t.

The image below is of the east end of the section under construction. I find a bit of irony here in that the “Bikes May Use Full Lane” sign is placed at the start of a project which intends to get bicycles off the road, and also it is nonstandard — diamond-shaped like a warning sign which is supposed to be yellow, but white like a regulatory sign, which is supposed to be rectangular (as with speed-limit and no parking signs). The message is a regulatory message: it is law.

Looking west at the east end of the Concord Avenue section under construction

Construction barrels divide the narrowed roadway into two lanes, rather than the three planned for when construction is complete. As the westbound bikeway is incomplete, I rode west on the roadway. Motorists still were able to overtake me without leaving their lane, as they were when the roadway was wider, with three travel lanes and a bike lane on either side. I was passed by a number of cars, no problem. I had one conflict with a driver who moved out of a side street into my path. Such conflicts will be much more common when bicyclists are riding in sidewalk space.

The road surface was very bumpy because the street has not yet been repaved. The effort is going into construction of the bicycle sidepaths at this time.

I shot video of my rides. It’s HD video and you will want to view it full screen to get all the details. This is the link to the video of my westbound ride. And here is my eastbound ride.

One other thing I hadn’t expected is that the south-side (eastbound) path was almost completely empty, except for me, though it was nearly finished, and unobstructed — on a warm, sunny Sunday afternoon when there was heavy bicycle and pedestrian traffic in Fresh Pond Park and on the Minuteman path.

I can say that if much traffic does appear on the south-side path, the situation will be very confused. There is no buffer between the 5′ wide bikeway (closer to the curb) and the wider walkway away from the curb. There was supposed to be a 2-foot-wide buffer, as I recall. Also, the concrete pavement of the pedestrian section, farther from the curb, is smoother. The bumpier asphalt pavement adjacent to the curb is supposed to be for eastbound bicyclists, in defiance of AASHTO guidelines, which require a 5′ spacing or a barrier, and also in defiance of normal path and road rules, which require riding on the right side. The City’s scheme would have eastbound bicyclists riding on the left side of the combined bikeway and walkway. Meanwhile, there also will be westbound bicyclists using this path to avoid the much worse path on the other side of the street, and probably keeping to the right as is usual.

As the path is behind a high curb, bicyclists who want to cross Concord Avenue will have to wait at the crosswalks rather than to merge into the roadway. At the few crosswalks, there is no waiting area (for example, at 1:24 in the eastbound video). Because the bikeway is between the walkway and the street, bicyclists and pedestrians who are waiting to cross the street will block the bikeway, and other bicyclists will have to divert onto the walkway.

As the concrete pavers of the pedestrian section and the asphalt of the bicycle section age and settle, a step could develop between them, just as on the parts of the Charles River paths, widened with asphalt next to the old stone retaining wall along the riverfront. Many bicyclists have gone down as a result.

Many aspects of the Cambridge bicycle program can be described as ideologically driven, and defying national and state design standards. Placing a longitudinal seam along a bikeway, and directing traffic to keep left, are merely incompetent.

Other than what I have described in this post, the project looks as though it will turn out as I expected, with the foreseeable problems I’ve already described in my earlier post; the right hook and left cross conflicts, inability to cross to the south side at most locations without dismounting in the street to lift the bicycle over a curb; resulting wrong-way riding on the north side, etc.

The party line about the Concord Avenue project, which I have in writing from two City employees (here and here) and verbally from a member of the Cambridge Bicycle Committee, is that “bicyclists will be riding in exactly the same place as they are now.” This statement turns a blind eye to the encouragement of wrong-way riding, and the keep right/keep left confusion. It ignores bicyclists’ crossing and turning maneuvers, and motorists’ being trapped by the curbs and forced to turn across the path of bicyclists; it denies that motorists block sidepaths so they can see approaching traffic in the street. Saying that “bicyclists will be riding in exactly the same place as they are now” is like saying that a bird in a cage, hanging in a tree, is in exactly in the same place as a bird sitting in that tree and free to fly off.

What really burns me up is that the City employees designing bicycle facilities appear to have no concept of how bicyclists actually are going to use them, or of the potential hazards. It’s all about “build it and they will come” and that means, build just anything they think will attract novice cyclists and children, and to hell with design standards and safety research. I see shoddy and incompetent mimicry of European designs, and astonishing hubris. So far, the Concord Avenue bikeway is half built with one side completely open, and very few bicyclists have come, except for me, and I was there on a discovery tour.

The city's own picture of this scene shows a cyclist happily steering straight toward a curb.

A picture of the same scene from the City's Web site shows a cyclist happily steering straight toward a curb, which is cropped out of the picture.

Looking from the opposite direction, this is the path a bicyclist must take, swerving toward traffic to reach the curb cut.

Looking from the opposite direction, this multiple-exposure photo shows the path a bicyclist must take, swerving toward Follen Street traffic to reach the curb cut at the crosswalk.

This post attempts to shed some light on agenda items on tonight’s City Council agenda.

The quoted sections are from another commenter. I’m not sure I know how to reach him, and time is pressing. I don’t know whether I have permission to use his name, so I won’t. The unindented paragraphs  are my own. We’ll start with the other person who commented.

Two of the three items on the city council agenda are interesting examples of problems related to bicycle infrastructure that has been implemented over the past several years.  The third is simply a request to fill potholes, but includes an ignorant comment about bicycles needing to ride near the curb (not true according to Massachusetts law or Cambridge ordinance).

That is agenda item O-7 on the page linked here

The first bicycle facility problem is a contra-flow lane through a blind corner where motorists have no expectation that there will be contra-flow traffic of any sort as they round the corner on a one-way street.

That is agenda item O-3 on the page linked here.

The street view is looking south on Follen Street as it intersects (Little) Concord Avenue.  The bike lane crosses in a contraflow manner from left to right, and then continues across the small brick plaza to the right to join with Garden Street and the continuation of Concord Avenue.  The intersection just beyond the plaza is the same one where Cambridge has installed a bike box critiqued by John Allen

(http://bit.ly/jQN595).

The contraflow bike lane is adjacent to wrong-way parking, another odd feature of this installation — see this for a description and explanation of wrong-way parking:

Upon reaching the corner, bicyclists have to ride out past a stop bar and stop sign before they can see around the corner. A stop sign requires two actions, a stop and a yield. The yield is what actually prevents a collision — but it is only possible where you can see conflicting traffic.

Many if not most of the bicyclists approaching this intersection are Harvard students headed up to the Radcliffe quadrangle. Are we to assume that they aren’t bright enough to figure out that they must yield? The problem is that nobody ever instructed them, and many have little bicycling experience as they suddenly find themselves dependent on a bicycle for transportation. Also, the stop bar isn’t where there’s anything to yield to unless a pedestrian happens to be crossing — it encourages running the stop sign, sort of like traffic ju-jitsu: aha– fooled ya!.

See Google Street View looking toward the stop sign:

I have a discussion of this contraflow bike lane in the page linked below this paragraph. The third photo down the page shows the stop sign. I prepared the page linked below years ago, shortly after the installation. This was clearly going to be a problem location.

The curb ramp on the far side of the intersection is located at the end of the crosswalk rather than in line with the bike lane. Bicyclists must ride toward approaching traffic to reach the ramp.

Bicyclists coming in the opposite direction off the little pedestrian plaza are hidden by a wall and subject to similar risks. This entire treatment is a prime example of Cambridge’s principle of Design by Wishful Thinking.

The second problem is at a rather unremarkable intersection, so it is not clear to me why there would be issues.

See Council Order O-19 on the page linked here.

The street view is looking south on Ellery Street as it approaches Broadway.  Ellery is a narrow one-way street with a bike lane.  Traffic is typically slow, but can be heavy at rush hour.  Broadway is a two-way narrow connecting through street with parking and no bicycle infrastructure in this area.  Traffic typically runs about 25-30mph, slower and heavier at rush hour.  The intersection is also at the corner of a local public high school campus.  Neither street is difficult to cycle on if you have at least modest traffic experience.

There is a flashing yellow and red overhead signal indicating a stop sign for Ellery Street entering from the north.  I tried to find data related to the several accidents cited, but did not see anything apparent on the Cambridge city web site.  I can speculate that most of the car/bike accidents are probably due to scofflaw behavior — either bicyclists in the Ellery bike lane not heeding the stop sign as they continue across Broadway, or wrong-way riders in the Ellery Street bike lane illegally approaching Broadway from the south.  Also likely would be standard right hook, left cross, and failure to yield collisions caused by motorists, but I don’t see why those would be any worse at this intersection.

I see a double-whammy right-hook provocation for bicyclists headed south on Ellery Street, in that the bike lane on the far side of the intersection is to the left of parking (and in the door zone, as is usual in Cambridge), while the bike lane on the near side is at the curb and carried all the way up to the intersection. So, bicyclists are encouraged to overtake motorists on the right, then merge left inside the intersection where motorists turn right.  I think that the high traffic volume and prevalence of high-school students probably also account for the number of crashes. There probably are scofflaw crashes too. Yes, it would be very interesting to see details so as to get a handle on what is actually happening here.

I’m not looking for any answers, but I thought people on this list might be interested in what Cambridge lawmakers are thinking.
