Central City Mobility update: I Street

2023/09/27 Dan Allison1 Comment

This is Central City Mobility Project update #26.

Work is occurring on I Street this week. The street has been marked from 21st Street to 12th Street, and some of the white striping has been completed. No green paint yet. This section is all right side of the street bikeways.

The design is rather erratic:

21st Street to 20th Street, parking protected separated bikeway
20th Street to 19th Street midblock, bike lane
19th Street midblock to 16th Street, buffered bike lane
16th Street to 13th Street, buffered bike lane
13th Street to 12th Street, parking protected separated bikeway

At the intersection of 21st Street and I Street, there are markings for dashed green bike lanes on the west, south, and east legs, adjacent to the crosswalks (not yet painted). No sign of the promised bike signal yet. The markings imply to me that bicyclists continuing north on 21st Street will have to make a two-stage crossing, first across 21st Street, and then across I Street. This is not what was advertised, which was that bicyclists would have an exclusive signal phase during which they could go to any of the three destinations without any moving motor vehicle traffic. To to seen.

At 20th Street, the street becomes three motor vehicle lanes (general purpose travel lanes) and a curb-side regular bike lane. I’m guessing this is to provide stacking area for motor vehicles when trains are crossing. Makes some sense, but it also makes the bikeway erratic, and will encourage poor behavior as drivers speed into the third lane, and then have to merge back into two lanes.

At 16th Street, the street design is two motor vehicle lanes and a buffered bike lane. The reason for this is that the Memorial Auditorium loading dock extends into the street, which was an earlier design mistake that the city made to choose auditorium convenience over people walking (Sac permanently closes sidewalk).

12th Street is the end of the project, and I Street is again a three-lane traffic sewer towards the freeway. At 6th Street it becomes a five-lane traffic sewer.

Since work is actively going on today, I would guess that the white paint will be complete by the end of this week, and green paint added next week. There is still a national shortage of the green K-71 vertical delineators, so I would guess that only a few will be placed in the near future. There are a few places with gaps in the white stripes, which will be a designated color for parking or loading.

NACTO protected intersection and Sac semi-protected intersection

This is Central City Mobility Project update #25.

I have been getting questions from several people about how the turn wedges being installed as part of the Central City Mobility Project are supposed to work. In particular, this applies to all of the concrete wedges, which are at the intersection of the separated bikeways, but applies most of the other wedges as well.

First, the diagram from the Central City Mobility Project design document. This is turn wedge style 3, with concrete turn wedge. The other four styles have speed bumps and vertical delineators.

diagram, Central City Mobility Project, turn wedge style 3

Second, a photo of an actual concrete wedge in place.

photo, concrete turn wedge at 21st St & P St

The issue that has been pointed out by more than one reader is that a motor vehicle driver can also cut between the turn wedge and the curb, to the left of the turn wedge, rather than to the right, as was intended by the design. Wow! That is a flaw. How did this happen?

Well, the city has designed partially rather than fully protected intersections. Not only are these protections only on one corner, but they are not designed according to NACTO (National Organization of City Transportation Offices) guidance. Here is the NACTO diagram, from the Protected Intersections page.

What is different? Look at the approach from the left side of the diagram. There is a concrete island, labeled 3, which prevents motor vehicle drivers from cutting through between the turn wedge (‘corner island’ is the NACTO term) and the curb. It is likely that the area labeled 1 would also be a concrete island. This island not only protects bicyclists, but more importantly, protects walkers and shortens the crossing distance. I will include text from the NACTO page below, because the details are really important.

So, how to fix the Sacramento problem? Concrete islands need to be installed in the upstream direction, before the crosswalk. In the case of the photo above, this would be where the photographer is standing. Without such protection, this cannot be considered in any way a protected intersection or separated bikeway (protected bikeway). The radius of the turn wedge is also much greater than the NACTO recommendation, 30 feet rather than less than 18 feet (see second bullet below). So we are back to ‘turn wedges of death‘. I have to say, this is typical of the city, to take a good idea and sort of implement it.

Thank you to the reader who pointed out this design flaw, and caused me to look more closely, and think more closely.

Central City Mobility update: 19th St

2023/09/192023/09/19 Dan Allison4 Comments

This is Central City Mobility Project update #24.

For quite some while, the project on 19th Street had stopped at Q Street, but it is now continuing south to W St. White striping is done, there is some green paint but incomplete, curb and line colors for special parking is not started, and there are no vertical delineators. The block from Q Street to the light rail tracks is a buffered bike lane, due to a street dining area at Midtown Spirits. At the tracks, there are some swooping lines, that I think are intended to encourage bicyclists to cross the tracks at a closer to perpendicular angle, but it is not finished so I can’t tell if it being properly marked. The remaining blocks to W Street are parking protection separated bikeway.

photo, 19th St at Q St, buffered bike lane — 19th St at Q St, buffered bike lane

The section from W Street to Broadway has not been worked on. As is true of most of the separated bikeways, it is on the left side. South of Broadway, 19th Street becomes Freeport Blvd and is two way, with the southbound bike lane on the right side. At the moment, there is nothing to indicate how and where a bicyclist would transition from right side to left side. The two blocks are devoted to general purpose (motor vehicle) lanes, and is not a comfortable place for a bicyclist to be.

In the design diagrams, the transition appears to be at W Street, with no particular accommodation for bicyclists. Though the design diagrams do not indicate operations, just striping and signing, it looks as though bicyclists will cross W Street on the east side, with the regular signal, and then 19th Street on the south side, with the regular signal. There is no indication that the bicyclist crossing 19th Street will be protected from left turning motor vehicle traffic by an exclusive phase. Green paint is not sufficient communication for most drivers, hard physical control is required, such as no left turn during the bicyclist movement. I suspect, based on city implementation in other locations, that it was decided that an exclusive bicyclist phase was ‘not practical’ because it would slow motor vehicle drivers a bit.

design diagram, 19th Street from W Street to Broadway — 19th Street from W Street to Broadway

I believe that the city should develop and install signing specifically for bicyclists on the transition points, where a bikeway either ends or transitions to the other side. There is no indication that the city has done or intends to do this. The diagram indicates a R55(CA) (MOD) sign on the southeast corner, which is a mystery, since the standard R55 sign is ‘yield to uphill traffic’. Of course neither the federal MUTCD nor the California CA-MUTCD, which is similar, has much in the way of guidance or signage for bicycle facilities, since in the mind of FHWA and Caltrans, bicyclists are an afterthought. There are several note references around this intersection, several of which I have been unable to locate in the design document, but they must exist somewhere. Be aware that the city has ‘invented’ a number of traffic control signs that are not compliant with CA-MUTCD, so the excuse that there isn’t an official sign is just stonewalling on the part of the city.

I Street

There has been no work on I Street in quite a while, since the resurfacing, but there are new ‘no parking’ signs posted with control starting today, 2023-09-19, so perhaps work is about to start again.

Central City Mobility update: turn wedges

2023/09/072024/01/12 Dan Allison1 Comment

This is Central City Mobility Project update #23.

Concrete islands have been installed for the turn wedges at P & 21st, P & 19th, Q & 19th, and just today, at P & 9th and Q & 9th. The planned locations of these turn wedge islands are the intersections of the separated bikeways. The Q & 21st one is not installed yet, and I did not see any on 10th. The other intersections will have a different treatment, rubber speed bumps and vertical delineators.

The islands are centered by stamps red concrete. The curbs are four inches, and sloped at about 45 degree angle. Apparently these are poured on top of the pavement, I did not see any sign of excavation below the surface.

In a brief observation, about 20% of the turning drivers hit these islands. This is not surprising, as they are new, and drivers have gotten used to taking these corners at high speed, passing over what was just painted areas. I admit I almost hit one, as I had been riding straight through these intersections rather than swooping with the markings. But I pay more attention that most drivers, so I didn’t hit it.

Apparently the purpose of these is not to provide a wait area or bike box for bicyclists, but to slow drivers and have them pointing more perpendicularly to the bikeway and crosswalk, so they are more likely to see other people. But they do offer an area where bicyclists can get out ahead of and more visible to drivers.

Updates

P Street, Q Street, 21st Street: No significant changes.

19th St: Markings for the separated bikeway are marked from Q Street at least as far south as S Street. Not observed south of there.

I Street: No change, still just lane marking tabs. Paving was continued to 12th Street, so it is possible the project will be extended that far, but as designed, the separated bikeway and lane reduction ends at 15th Street.

10th Street: No significant change, is largely complete but some marking and delineators are still missing.

9th Street: I had speculated that the project would not be completed from L Street to Q Street, but it has been marked and partially painted now. There is a left side regular bike lane (two white lines but no buffer) from L Street to O Street, then mixed left side bike lane and separated from O Street to Q Street.

5th Street: No change.

Central City Mobility update: 9th, 10th, I

2023/08/282024/01/12 Dan Allison2 Comments

This is Central City Mobility Project update #22.

9th Street: 9th Street has a pavement overlay from L Street to Q Street. This is not repaving, removing old pavement and placing new, as has been done on many of the streets in the Central City Mobility Project, but a thin overlay. This was done very recently and there is no marking of any sort on the street. I had guessed that this section of 9th Street would not receive any treatment until the construction projects were complete, but I was wrong. I don’t know what kind of roadway allocation will be done in these five blocks. The left side is constrained by construction from L to Capitol Mall, and the right side from N Street to O Street and from P Street to Q Street. Note that in the photo below, there is a bus stop on the right hand side, which is why the city has designed the separated bikeway design on the left side.

10th Street: 10th Street is largely complete from W Street to Q Street, where a pre-existing separated bikeway continues north, but a few things are left unfinished and not all of the green vertical delineators have been installed. The block from Broadway to X Street has been marked. It does not appear that anything will be done with the block from X Street to W Street, under the freeway.

10th Street from Broadway to X St, new markings for separated bikeway

I Street: Nothing has been done on I Street since the pavement patching. There are lane marker tabs for three general purpose lanes and no bicycle facilities.

19th Street: Work south of Q Street is now underway, with repaving complete and the beginnings or markings for the left side separated bikeway. I have not ridden south on 19th to see what is being done beyond this point.

19th St at Q St, initial markings for separated bikeway

There is no change to the ‘turn wedges of death‘. The bicycle signal at 21st Street and I Street has not been installed. No further work is in evidence on 5th Street.

Central City Mobility update

This is Central City Mobility Project update #21.

I have been backpacking and traveling, so not keeping up as much with the Central City Mobility Project. I may do updates on my days back in town, about once a week.

19th St: Paint and vertical delineators are mostly complete from H St to W St. Nothing has happened in the two blocks from W St to Broadway. Though pavement has been patched from Q St to W St, no other work has occurred.

21st St: Paint and vertical delineators are complete from W St to I St. No bicycle signal at I St, so the intersection of 21st St and I St remains extremely hazardous to bicyclists (and walkers).

P St: Paint and vertical delineators are complete from 21st St to 15th St.

Q St: Paint is mostly complete from 14th St to 21st St. Vertical delineators have been installed on some blocks but not others, probably due to materials shortages. Some crosswalks are missing.

10th St: Paint is mostly complete from W St to Q St (Q St to I St was already ‘complete’ before this project). No vertical delineators yet. The block from Broadway to X St has a traditional bike lane on the right, but no changes. The block from X St to W St, under the freeway, has a wide right side shoulder, but it is not a bike lane, nor is it marked as such. The parking-protected separated bikeway on 10th St is on the right side, because 10th St does not have bus service to be accommodated by a left-side bikeway.

9th St: Other than some patching, nothing has happened on 9th St. The new bikeway from L St to Q St will be on the left side. A construction project from L St to Capitol Ave closes the left side bike lane, and there is no accommodation for bicyclists. Though there is a bus area on the right, followed by a parking lane, it is not marked as a bike lane, nor is it safe as a bike lane. There is no signed on 9th St approaching L St to indicate that the bikeway ends, nor how to ride south. See photo below.

9th St at L St, no bicycle accommodation

Another construction project from O St to P St closes the right side of the roadway, but the existing bike lane on the left hand side is still open. As previously noted, it is unlikely that the bikeway on 9th St will be installed until both construction projects are complete.

I St: Other than pavement patches, no other work has taken place. No-parking signs continue to be up even though no active work is occurring. Most blocks from 21st St to 12th St will be reduced from three general purpose travel lanes to two, but from 20th St to 19th St, and part way to 18th St, the three lanes will be retained. It is not clear why.

5th St: No further work has occurred.

Nothing has changed about the ‘turn wedges of death‘. A closer look at the design diagrams (thanks to the person who provided them) shows that the wedges at intersections of the separated bikeways are intended to have hard curbs, 4 inches with sloped sides (regular curbs are six inches or more) with stamped concrete interiors (style 3), but the other intersections will have ‘rubber speed bumps’, and vertical delineators. The bumps are apparently as shown in the photo below, though the photo shows a bump in the travel lane, and these are in the turn wedges. The bumps are 2.25 inches high, which won’t be even noticed by trucks and SUVs, though might be noticed and respected by passenger car drivers.

19th St gutter fix

2023/08/092023/08/16 Dan AllisonLeave a comment

This is Central City Mobility Project update #20.

Apparently it does help to complain, at least sometimes. The city is fixing the root heave and gutter on 19th Street between Matsui Alley and N Street, which I posted on recently (hazardous bikeway on 19th St). I had submitted several 311 reports on this issue, and so had other people, and it seems we got through to Public Works.

The gutter is being replaced at the root heave, and other deteriorated locations in that half block. The photo below shows a night-time view, and I’ll add a daytime view and a view when the project is complete. Note that the bikeway is being appropriately diverted into the parking lane. It is unusual for the city to provide an equivalent accommodation for bicyclists.

gutter fix work on 19th St bikeway between Matsui Alley and N St

Of course there are several more blocks on 19th Street where the gutter pan is deteriorated enough that it doesn’t provide a bikeway surface and the bikeway therefore does not meet standards. However, this was the worst and most dangerous location, so there is progress.

hazardous bikeway on 19th St

This is Central City Mobility Project update #19.

I have mentioned the problems with the gutter pan on several blocks of the new bikeway on 19th Street being so deteriorated that the effective width of the bikeway is only about two feet. It is clear that the city did not look at the existing conditions of the gutter before deciding to place the bikeway in this gutter. But, this is not an easy thing to fix. There are at least four blocks that are unacceptable, but it will probably require reconstruction of the gutter pan to fix it.

What can be fixed, but has not been, is the root heave in the 19th Street bikeway at Matsui Alley (note that Matsui is discontinuous, and is present only on the west side of 19th Street; the alley does not exist on the east side.) The photo below shows the root heave, but doesn’t really emphasize how big it is. There is a four inch displacement. This is a pavement flaw that could easily cause a bicyclist to crash. I don’t know whether the orange paint marking is from the city or bicyclists, but orange paint is not visible at night, and even in daytime it doesn’t make clear what the rider should do to avoid the hazard.

19th St bikeway at Matsui-Alley root heave — 19th St bikeway at Matsui Alley root heave

I have reported this issue to the city 311 app several times. I know of at least two other bicyclists who have reported it multiple times. The city 311 incident map shows only my latest report (230805-1907594), which means that the city has closed all the other reports without any action.

Allowing this type of hazard to exist, when it is a known hazard, particularly in a location designed to attract bicyclists, is criminally negligent. Let me repeat that for the idiots in Public Works, who seem to be hard of hearing – CRIMINALLY NEGLIGENT.

If you are a bicyclist who is using 19th Street, I encourage you to NOT use the bikeway in this block between Capitol Avenue and N Street. Ride in the middle of the general purpose travel lane instead. And if you have the time, file a 311 report on the hazard. It will become increasingly difficult for the city to claim it didn’t know about this problem (by closing the reports without action), the more people report it.

Central City Mobility update K71, curbs

2023/08/042023/08/04 Dan AllisonLeave a comment

This is Central City Mobility Project update #18.

Flexible delineators have been installed along part of 21st Street, and are undergoing active installation this week. These K-71 posts are more substantial that the traditional vertical delineators. They can still be run over, and are run over, but since they look more substantial, drivers are less likely to run over them. They are still plastic, so provide no actual protection from errant motor vehicles; only hard curbs or true bollards (steel or concrete) can do that, but still, an improvement over earlier designs.

Central City Mobility Project, 21st St, K71 delineators

I don’t know how quickly the otherwise completed sections of the Central City Mobility Project will have these delineators installed. Apparently there is a US-wide shortage of materials for separated bikeways, and many cities are not able to complete their projects.

A second change since my last posting is that some parking spot paint is showing up. I had thought that parts of the striping that were still missing after quite some while were just missed, but in fact at least some of them were intended for parking regulation marking. The photo below shows a yellow curb and yellow stripe adjacent to the parking spots. I am glad to see that both the curb and the parking lane are being marked with paint. Otherwise, many drivers would fail to see, or pretend not to see, the curb color alone. This is hard to miss!

Central City Mobility Project, 21st St, yellow curb and parking marking

In California, painted curbs have the following meaning:

red – no stopping, standing, or parking
yellow – commercial loading and unloading (can also be used for passenger loading and unloading, unless otherwise signed)
white – passenger loading and unloading
green – limited time parking, as posted on a sign or the curb
blue – disabled parking (must have a license plate or temporary hanger tag)

In Sacramento, and many places in California, parking enforcement takes a laissez faire attitude towards curb colors. Except for red curbs, they are seldom enforced, and even red curb enforcement is uneven. Note that red curbs are really intended to mean what they say. If you stop there, you are in violation. A typical driver excuse for any parking violation is that they were ‘just going in for a moment’. Moments turn into minutes turn into hours, as I have observed many, many times. If you get out of your car, you are parking, no matter what the driver calls it, the law calls it parking. Parking on white and yellow curbs is a violation. Obviously commercial loading and unloading may take some time, but if there is no active loading or unloading going on, that is a violation.

I like green curbs as a solution for businesses where people pick up food and beverages. Fast food places where people order ahead. Coffee shops. My local coffee shop has a green curb right outside, and it is used for its intended purpose by some drivers. Other drivers just take it as an open free parking spot. I have reported these to city 311 as violations, but the city has not enforced so far as I am aware. More green curbs, please! (note that in the photo, the motor vehicle had just pulled into the curb, and the driver was crossing the street to pick up food at one of the businesses on the west side of 15th St; the parking meters are not functional, but the 15 minute limit is clearly posted)

green curb 15 minute parking, 15th St, Naked Lounge

Because past enforcement has been laissez faire, it will take some signing and education to make these curb colors work. Most drivers in California don’t really understand curb colors; I used to work in Nevada, and I can tell you most drivers there know exactly what they mean.

I am very pleased to see that curb colors are being more actively used in the city. Illegal parking endangers bicyclists, in particular, but also walkers and drivers. Of course something must be done to get delivery vehicles out of bike lanes and out of blocking streets and crosswalks. The city is far, far from having a plan to address that.

Other

19th St: no active work south of Q St

10th St: street being prepared for repaving and re-striping

I St: street being prepared for repaving and re-striping

5th St, 9th St: no active work

Nothing has been installed in the ‘turn wedges of death‘. I looked at the detailed design for these turn wedges (another advocate was able to obtain them), and it is still not clear what is intended for these locations. The bicycle signal at 21st and H Sts has not been installed, nor is there any sign cautioning bicyclist from using the pedestrian signal, which exposes them to high speed left turning motor vehicles.

change it before someone gets killed

This is Central City Mobility Project update #17.

I regularly ride the newly repaved streets with separated and/or parking protected bikeways, because I want to see how bicyclists and drivers are dealing with the new design. Well, the turn wedges are a complete failure. At every intersection where there is a turn wedge for left turns, drivers are cutting the corner and turning at higher speeds than they did before. The city has created a danger that was not present before, when there were regular bike lanes. The city has not completed work on the turn wedges, and for now, they are an incredible danger to bicyclists. The city has not placed construction signs at these locations, though at least according to the rough designs the city has shared with the public, construction is not complete. Nothing has been installed in the turn wedges. That means that the city has left the project in an incomplete state, but is communicating to the public that the project is complete.

The number of close calls that I have personally experienced at these turn wedges now numbers over 40. As an experienced bicyclist, I know what to watch out for and respond, but having to slam on my brakes to keep from getting run over is not something I or any other bicyclist should have to do.

The city must stop this madness before people die. The city knowingly has installed unsafe roadways, and has not fixed them despite knowing that they are hazardous. This means that the city is legally responsible for any bicyclist-driver crashes that happen at those corners. I will happily testify against the city, and hope that they have to pay our millions for their incompetence. But of course someone will be dead or severely injured, and the city won’t have to be liable for that. Traffic engineers depend on ‘approved’ designs to isolate themselves from direct legal responsibility, but these are not approved designs, they are ones that the city invented using pieces and parts of internationally recognized designs.

City, fix this now, or suffer the consequences!
