surface parking to residential

2018/10/032023/03/19 Dan AllisonLeave a comment

Wasted space for parking. This was once residences, and should be again.

Part two of posts about O Street activation, but also of more general applicability. See also my related post No more pure office buildings downtown.

The activation of O Street under the CADA-led ‘Envision O Street: A Community Planning Process to Transform the Streetscape‘ effort will be only partially successful unless there are a lot more residents along O Street and the adjacent neighborhood to activate it. As it currently stands, the street is largely dead evenings and weekends. Even the homeless folks don’t much like hanging out there.

So, forthwith, my modest proposal. All surface parking lots along N, O, P and Q streets will be transferred to CADA and developed for residential and/or mixed use. These developments might even include some office space, but no development would be purely office. We have enough state office space as it is, and we have enough parking garages (decks) as it is. Significant parts of the parking decks are empty even on weekdays, and they are completely wasted space the rest of the time. Many of them are even locked up evenings and weekends, so they could not be used even if people wanted them to be used. The state seems to not care about whether downtown and its part of midtown (extending to 17th Street) are dead. It sees downtown as just a collection of office buildings, and is fine with the buildings and streets being empty off work hours. The state also believe that it is their responsibility to provide unlimited parking for their employees, no matter how much that parking decreases the livability of the places they work. I’m not sure if these attitudes come only from DGS (Department of General Services) which manages state property, or is a more general view, but it is wrong. The state should be encouraging workers to get out of their cars and onto transit (light rail runs on O Street), bicycles and foot, not providing them free and low cost parking. The state should be encouraging livability, not thwarting it.

All surface parking lots along N, O, P and Q streets will be transferred to CADA and developed for residential and/or mixed use.

O Street Activation

2018/10/032023/03/19 Dan Allison3 Comments

CADA (Capital Area Development Authority) is undertaking a process to activate O Street between 7th and 17th streets in downtown and midtown Sacramento. There was a community meeting at noon today, which I participated in. Not many people there, but there is also a meeting this evening which might gather residents who work during the day.

There are a lot of intriguing ideas and overall I think the draft framework is a good one. CADA said the diagrams and maps would be posted within a few days, so you will be able to see them at http://www.cadanet.org/projects/o-street-improvements-project.

Some comments I made:

the design needs to be compatible with the new light rail stations that will be constructed, probably in phases, to accommodate the new low-floor rail cars which require an 8-inch curb above the rails; the mini-high platforms needed for the current fleet of high-floor rail cars will eventually be removed, making for a much more pleasant street environment
rather than putting in bicycle facilities on O Street, separated bikeways on P Street and Q Street (partially complete) and N Street (not started) should handle most of the through bicycle traffic; instead, these things should be done to make the street bikeable without any special facilities:
- speed limit 15 mph throughout
- most sections become single-lane one-way, with narrowed travel lane; where two-way sections are needed (if at all), streets should be narrowed significantly
- textured pavement, for streets or crosswalks or intersections, should either be sufficiently smooth to accommodate bicyclists, or have smooth pathways specifically for bicyclists
without bicycle-specific infrastructure, more of the right-of-way width can be devoted to pedestrians, sidewalks and the amenity zone; the pedestrian space will make the biggest difference in how the street is perceived
no section that is now closed to motor vehicles (9th to 10th and 11th to 12th) should be opened to motor vehicles, and no section that is currently one-way should become two-way
all corners should have bulb-outs (curb extensions) to calm motor vehicle speeds, reduce crossing distances, and preserve visibility at corners from parked vehicles; many corners are proposed for bulb-outs, but not all
raised intersections should be considered for all intersections
traffic on 15th Street (southbound) and 16th Street (northbound) must be calmed; it is currently difficult and hazardous for both walkers and bicyclists to cross through these intersections, traveling along O Street

The big issue, though, is that there is insufficient residents along the corridor, specifically between N Street and Q Street, to activate the corridor. More about that in my next post.

The improvements to O Street will be very expensive, if all are completed, but there are low cost items to start with, and I’m hopeful about seeing some of these in the near future.

preserving access during construction

2018/09/282021/03/20 Dan AllisonLeave a comment

Sacramento central city is booming with construction, which I consider to be a wonderful thing. Mixed use buildings, single lot apartments and homes, state office buildings. But the construction is having a serious impact on walkability, and often bikeability. (Note: this post is not about road construction or about temporary closures, which also need to be addressed, but not today.)

Two examples, both of state developments, but with principles applicable to private developments, will illustrate the issues. For the new California Natural Resources Agency building between O and P, and 8th and 7th, the sidewalk, parking and one travel lane on the south side (P St) were removed from service. These are not being used in any way for the project. Perhaps they will be eventually, but in the meanwhile, presumably for the entire life of the construction project, they are just sitting empty and unused. For the new O Street office building at O and 12th, the sidewalk and parking were removed from the east side of 12th between the N-O alley and the O-P alley. The section to the north, where the building is being constructed, needs closure, as the underground level is being dug and the sidewalk will be replaced. But on the section to the south, which is being used for storing construction materials, do not need to be closed. There is plenty of space on this former parking lot.

For some of the private construction going on, of which there are many examples, some closures are no doubt necessary. But the closures seem to be occurring from the very first day of construction to the very last day of construction, even though it is needed for only part of the time.

Construction companies are doing this because they can, out of convenience or laziness. And the city is allowing them to. Each construction project requires a traffic control plan, and the permit specifies allowable areas and time frames.

When I questioned the closure on the southern section of 12th Street, Matt from Construction Services in Public Works argued that since parking was removed, it was only fair that the sidewalk access be removed. His thinking was that fairness required making everyone lose something, and that the loss of parking was equivalent to the loss of sidewalk access.

This of course is a ridiculous argument. Parking is in no way equivalent to access. And priority must be given on all roadways to the most vulnerable users, which are in order of importance, pedestrians, bicyclists, and motor vehicle drivers.

At the recent Sacramento Active Transportation Commission meeting, Jennifer said that she though there might be guidance on access restrictions, but wasn’t sure, and would look into it.

In the meanwhile, let me propose:

For any roadway with more than one lane in a direction, space will be taken from a general purpose travel lane:
- If a sidewalk or informal walking path is present, pedestrian access will be preserved by the creation of a temporary sidewalk protected by delineators or barriers.
- If a bike lane or separated bikeway is present, access will be preserved by the creation of a temporary bike lane protected by delineators or barriers.
For any roadway with a single lane in a direction, space will be taken by closing the general purpose lane in one direction, with appropriate detours for motor vehicles:
- If a sidewalk or informal walking path is present, pedestrian access will be preserved by the creation of a temporary sidewalk protected by delineators or barriers.
- If a bike lane or separated bikeway is present, access will be preserved by the creation of a temporary bike lane protected by delineators or barriers.

JUMP update

2018/09/252021/11/05 Dan Allison1 Comment

The credit for returning a low battery $ bike to a drop zone is now $1.00, up from 50 cents.

I notice a lot of scrapes on the bikes. It seems that there are a lot of minor crashes occurring. I have not heard of any major injuries, but there must be a lot of minor injuries going on, because there are minor injuries to the bikes. In addition to the scrapes on the basket, the brake lever, particular the right, is often turned under, which requires some impact to accomplish. The front fenders seem to get bent out of alignment as well.

I have heard directly from several people about crashes on the tracks, particularly along K Street. I initially discounted the rumors, as I assumed that it would be hard for these wide-tired bikes to have problems with tracks, but apparently I was wrong. I’m not sure if these are occurring at the rail crossover (between 9th and 10th), or all along K. K probably sees more bike share bikes than any other street with rails in Sacramento. There are many inexperienced bike riders on these bikes, who may not know that tracks should be crossed at a high angle, 90 degrees perpendicular if possible, but at least 45 degrees. Anything less risks capturing the wheel and taking you someplace you didn’t intend to go.

There seem to be new bikes out (nice and shiny, without scrapes), with 6000 series numbers, so I think that the overall total is now above 600, but I don’t have any specific numbers.

I’m seeing more and more bikes outside the system boundary in Sacramento, some miles outside. I’m not sure if JUMP has given up on charging the out-of-bounds fee, or these are people with money to pay it, but it kind of irritates me, as these bikes are often unavailable until picked up by JUMP field staff, meaning they are used much less than those that stay within the boundaries. I know that an expansion of the boundaries is planned, but I’d heard it will not occur until the system reaches its total of 900 bikes.

The transformation of the central city continues, at least during evenings. There are many fewer private vehicles, fewer ride hailing vehicles, and a continuous stream of JUMP bikes. When I park a bike, it is often gone within five minutes. These bikes are getting used!

Roundabouts and traffic circles

2018/08/27 Dan Allison8 Comments

It is common for people to use the terms roundabout and traffic circle interchangeably, as though there is no difference between the two. Sadly, Streetsblog San Francisco, whose mission is to educate the public, claims that there is no significant difference and that it is OK to use the terms interchangeably (SFMTA Launches “Muni Backwards” Program). That is not true.

A roundabout has two very significant features:

significant horizontal deflection which slows traffic
yield signs at all approaches

Traffic circles do not usually have these features.

Sac_7th-St_roundabout — roundabout, Sacramento

The photo at right shows a roundabout in the River District/Township 9 in Sacramento. It is quite a bit bigger than a roundabout needs to be, and was installed in a new development, not at an existing intersection, but you can see the deflection and yield signs.

Significant horizontal deflection means that vehicles must change significantly from a straight line of travel, which requires that they slow significantly. This slowing reduces the number of crashes somewhat, and almost eliminates the number of severe crashes and fatalities (about 80% reduction). They are safer because they greatly reduce the number of conflict points in an intersection.

Yield signs on all approaches means that vehicles only have to stop for other vehicles already in the roundabout. Otherwise, they proceed at their reduced speed and never have to stop. This yield approach benefits motor vehicles and bicyclists who ride in the travel lane. It does not, and is not really intended to, benefit bicyclists in bike lanes or pedestrians, but at the same time, if does not hurt them. There is one standard MUTCD sign used at roundabouts, shown at right, but you will also see many other signs at both roundabouts and traffic circles.

Traffic circles vary widely in size, and therefore the amount of deflection. At least in California, they almost always have stop signs on two of the approaches, so that one street does not stop and the other does. The photo at right shows a traffic circle in downtown Sacramento. It has some deflection, but not enough to really slow traffic, and with the stop sign, does not ease the flow of traffic. These traffic circles also squeeze bicyclists who do not know they need to take the lane to safety navigate the intersection. The traffic circle sign is not a federal or state standard sign, but does communicate.

There are a a number of traffic circles in Sacramento central city, most of which were put in years ago, but a few newer ones also exist. Depending on the size of the circle, they have varying traffic calming benefits. The reason traffic circles are used instead of roundabouts is that you can’t just plop a roundabout into the footprint of an existing urban intersection. They require more space.

There are a lot more features of roundabouts than just the two that I mentioned. If you want to become a traffic nerd on roundabouts, I recommend the FHWA roundabout page, particularly the publication Roundabouts: An Informational Guide, Second Edition. For an international best practices perspective that focuses on bicyclist benefits, check Explaining the Dutch roundabout abroad.

Multi-lane roundabouts probably do not have significant safety outcomes over regular intersections. Many Sacramento people have experienced multi-lane roundabouts in Roseville and in Truckee at the Interstate 80 – Hwy 89 interchange. It makes me nervous to even watch these, and I always label these as multi-lane roundabouts to distinguish them from single-lane roundabouts or just roundabouts, which do have very significant safety outcomes.

SF_new-traffic-circle-McAllister-Lyon Lastly, the type of traffic circle that engendered the discussion in San Francisco is at right. It has several non-standard features, even given the variability of traffic circles.

Parking in the protected bike lane

2018/08/27 Dan Allison2 Comments

People are again parking in the protected bike lane (correctly called a separated bikeway in California) on 10th Street in Sacramento, approaching K Street. This happened for about two weeks after the facility was installed, and then seemed to stop as people adjusted to a different street configuration, but now it is happening again. I was not sure whether this is illegal or not, but the city confirmed that it is illegal. The parking meters are for the parking spaces in the parking lane to the left of the bike lane, not for the curb. Confusingly, the red curb was painted over, probably in a misguided attempt to follow city design guidelines without thinking about the real world.

The bike lane here needs to be changed to prevent this from happening. The 10th Street bikeway is full of compromises made with parking. Mostly, it works, despite that, but in this particular place, it does not.

Next year, a real earth day

2018/08/272018/08/27 Dan AllisonLeave a comment

I have been long frustrated with the drift of Earth Day into irrelevance. I helped organize the first Earth Day in Las Vegas, 1970, when I was 18 years old. I and my one-year-older friends who were attending the university had a lot of hope for the future and really wanted a celebration of the earth, and of the change we know had to happen. In the years since, regulation has solved a lot of our pollution problems, but forward progress on that has stalled, and been reversed by the present administration. Most people are now far more disconnected from the earth than were people back then, spending a lot of time with devices and very little with the earth. So, I’d like to suggest some ideas for the next Earth Day.

First, it is a weekend, not one day. One of the days, everyone heads for natural environments, and spends time there with friends and family, sans electronic devices. For large numbers of people in the US, access to natural areas is difficult, and almost requires a car. So I’d encourage carpooling and provision of free public transit on that day. Nationwide. In Sacramento, we are fortunate to have the American River Parkway and several other natural areas not far from transit, so long trips are not necessary. Yes, I’m serious.

The second day (the order is not important to the concept), we all gather and shut down a major road, creating an open street event. No permits, this is an action of the people having nothing to do with government and police. If the agencies who populated the booths at last year’s Earth Day really feel they have something to say and share, they can come, bring some displays and materials, as much as they can bring on a cargo bike. No driving. People will be strongly discouraged from driving to the event, in all of the publicity, so it needs to be somewhere close to transit so that people can make their entire trip, or at least the last part, on transit. Again, free transit for the day. Nationwide. The electric vehicles, which have nearly taken over Earth Day the last few years, are not welcome. They are not a significant part of the solutions we need. Electric cars running entirely on solar energy is a dream that is many years away, and in the meanwhile they are still really running on fossil fuels and nuclear energy. The better solution is just to not use cars at all. Yes, I’m serious.

The point is that the people take back Earth Day from the sponsors, and make it an event of the people. People spend the two days talking about how they can change their lives, and how we can come together to change culture and society. Hopefully we commit to taking action every day to end fossil fuels, but also end consumption and inequity and income inequality, take back our government from the rich and the corporations, end industrial agriculture, and house everyone. Earth Day should be the first day of radical action to make the world a better place. Yes, I’m serious.

Since hopefully everyone is participating in these two days, much of business as usual stops. If it doesn’t have to do with caring for and celebrating people and the earth, it doesn’t need to happen. Yes, I’m serious.
