the problem with rolled curbs

2013/09/042013/09/04 Dan Allison1 Comment

Rolled curbs slope up from the gutter pan to the sidewalk, whereas standard curbs have a more vertical face. Standard curbs are both old and modern, but there was a period of time in the 1950s through 1970s when rolled curbs were very popular, seen as a sign of the new suburbs. In the grid area of Sacramento, including the first ring suburbs, standard curbs are quite common. In the second ring suburbs and the sprawl suburbs, rolled curbs are quite common, not only being found in residential neighborhoods but even on arterial roads.

parking up on the sidewalk with rolled curb

So, what’s the problem with rolled curbs? Drivers use rolled curbs to drive up on the edge of the sidewalk, constraining the sidewalk width, reducing walkability, and not infrequently causing blockage of the sidewalk for people in wheelchairs. ADA regulations require at least 36 inches of clear width. Combine the narrow 4-foot sidewalks that were popular in the suburbs with this driver behavior, and the car-influence zone is expanded to the complete width of the right of way, leaving no place for pedestrians. [Note: This photo is for illustration purposes only, not to give this driver a hard time. This is common practice, and I’ve seen many instances where much more of the sidewalk was blocked.]

A side affect of parking up on sidewalks is that it leaves more of the street width for moving motor vehicles, which then increases the speed at which people drive. By trying to get their vehicles out of the way of the “speeding drivers,” they are actually making it easier for drivers to speed.

What are the solutions?

whose responsibility are sidewalks?

broken sidewalk, Sutterville Road at 24th Street

Note: As I wrote this post, I realized that some background info was needed, hence two related posts: sidewalk buffers and surprisingly good sidewalks.

This week an article in the Sacramento Business Journal, “Rancho Cordova wants to make sidewalks problem of property owners,” talked about the city’s efforts to shift responsibility for sidewalks to the property owners, both residential and commercial. The city spokesperson, Davis Gassaway, attempts to gloss over the impact by saying that it should only cost $1000-1500 to repair a sidewalk, and that Sacramento, Roseville, and West Sacramento already have such ordinances. I think the costs quoted are on the low side. At about $4 per square foot (significantly more for curbs), $1000 would buy 50 linear feet of five foot wide sidewalk in a residential area, and 25 linear feet of ten foot wide sidewalk in a commercial/mixed use area. And just because another city is doing it doesn’t make it a good idea. So, what’s wrong with the idea?

repaired sidewalk around tree, P Street at 16th Street

When working on my post about responsibility for sidewalks, I realized I did not have a good illustrating photo for the post, so I went off walking in my neighborhood (midtown) looking for examples of broken sidewalks. After walking a couple of miles, I’d found only a few, and they were not bad. I guess my view of the world has been jaundiced by the time I spend in the suburbs, where many of the sidewalks are broken and deteriorating. There, it would take me less than a block in most areas to find something wrong with the sidewalk, or to find no sidewalk at all.

In midtown, that is not so. I see a lot of places where the sidewalk has been replaced or repaired, often many times over the years, in a patchwork of concrete of varying ages. There are asphalt patches over uneven sections, which work as long as they are kept up to date, but must eventually be repaired by removal and replacement.

sidewalk buffers

2013/09/022013/09/02 Dan Allison2 Comments

The purpose of sidewalk buffers, also called planting strips, is to isolate pedestrians from moving motor vehicles, where parking does not provide a sufficient buffer. Sidewalks adjacent to the curb are called attached sidewalks, while sidewalks with a buffer are called detached sidewalks.

Traditionally all residential, collector, and arterial streets had buffers. Retail areas often did not, in order to make getting from the car to the sidewalk more convenient.

Modern suburbs, however, usually eliminated the buffer strip from all streets in order to maximize the area available for development and roadways. Pedestrians do not like to walk next to fast traffic. In part, the elimination of buffers is why there is much less walking in the suburbs. The lack of buffers also makes an area look harsh, with a bland expanse of pavement rather than the welcoming and beautiful strip of nature. The planting strips and their vegetation require maintenance, and responsibility for those areas is another question of responsibility.

Choosing streets to walk

2013/08/17 Dan Allison2 Comments

business on a two-way, two-lane street (Capitol at 18th)

I walk a lot in midtown, going to and from various destinations such as the train station, nonprofits and agencies I work with, grocery stores, theatres, farmers markets, breweries, etc. I was thinking last night as I walked to and from Capital Stage about what streets I choose to walk on.

Almost all the time I choose to walk on two-way, two-lane streets. I rarely choose to walk on the multi-lane streets and the one-way streets, except for short distances as I zigzag to my destination. The two-way, two-lane streets are usually quieter, less traffic and traffic moving more slowly. I can relax more with the quiet, and I can look around more, paying more attention to everything around me and not just traffic.

Why is this significant?

Teaching children to cross

children crossing, Fauntleroy at Alaska, West Seattle (Seattle Bike Blog)

Streetsblog today posted an article “Our Streets Fail to Work for Children” which referred in turn to articles from Akron and Seattle. I commented on the Seattle Bike Blog post “We are failing our kids: A look at Seattle’s terrifyingly normal streets,” but I’d like to amplify my comments and specifically talk about pedestrian education.

Poor pedestrian infrastructure, as documented in these posts, is everywhere, more so in the suburbs and rural areas than in urban areas, but everywhere. The problems include:

The I Street mess

2013/04/032024/01/21 Dan Allison2 Comments

Thank you, Elle, for reminding me in your “transportation ‘planning’ downtown” that I wanted to write about I Street. Note: If you are looking at Google Maps, it does not show the current lane configuration on I Street since the repaving and re-striping project of last fall, nor the realignment of tracks and work on extending 5th and 6th streets over the tracks.

I Street from the 4th Street crosswalk; I have the walk signal but this is still scary

I Street in Sacramento approaching the train station is a mess. Starting with the confusing floating bike lane between 7th and 6th streets (subject of a future post), the street becomes worse and worse: five lanes wide, high speed, and completely unfriendly to bicyclists and pedestrians. For pedestrians, the crossing on the east side of the I/5th intersection is uncomfortable because westbound traffic is already moving at high speed and often runs the red light, and right turning cars from I to 5th often do not yield to pedestrians in the crosswalk. The west side is so unsafe due to traffic turning left off 5th Street, it is signed against pedestrian crossing, even though this is a logical walking route from downtown to the train station. A crosswalk has been added on the east side of the I/4th intersection, but it has the same challenges that drivers are moving too fast and often run the run light. When I used this new crosswalk, I was very concerned, and I have a much higher tolerance for danger than most people do.

The right-most two travel lanes lead to the high-speed northbound I-5 freeway onramp, so drivers passing 6th Street are already accelerating to freeway speeds, many times going 55 mph as they cross through the I/5th intersection. The next two lanes lead to a medium speed onramp to the I Street bridge over the Sacramento river, and to the southbound I-5 onramp. For pedestrians, the only way to go westbound towards Old Sacramento is to go through the parking lot for the train station and under the onramps along an ugly, dark, poorly marked pedestrian way.

Walkable City – live chat

2013/01/032013/01/03 Dan Allison4 Comments

I participated in the Walkable City live chat sponsored by Sacramento Press today, which featured Jeff Speck, author of Walkable City: How Downtown Can Save America, One Step at a Time, William Burg, and host Jared Goyette, which I advertised yesterday. I enjoyed hearing from both Speck and Burg. Burg is sort of the historian laureate of Sacramento, and his local perspective really added a lot.

You can review the recorded live chat by following the link from the live chat link above, and I highly recommend that you do. My take-aways from the conversation are:

Jeff Speck reiterated his “General Theory of Walkability” which defines a favored walk as including the elements of useful, safe, comfortable and interesting.
Speck said that in order to be walkable, a place must have “good bones”, short blocks in a grid pattern, with squares. Nearly always, these are pre-war neighborhoods. Burg pointed out that Sacramento downtown and midtown does have this, though our blocks are longer than many highly walkable cities, but our grid has been broken severely by the freeways and to some degree by the downtown mall and the convention center.
Speck said that many cities that have a great reputation for walkability started with just one great street, or even one great block, such as LoDo (lower downtown) in Denver. The one great place increased the draw for young creatives, which led to more widespread changes.Read More »

Walkable City

2013/01/02 Dan Allison2 Comments

Sacramento Press is sponsoring a live chat with Jeff Speck, the author of Walkable City: How Downtown Can Save America One Step At A Time. The live chat is tomorrow, January 3, at 12:30PM. The offline chat is already going on, if you want to check it out. I am currently reading the book, in the Kindle version, but am only part way through.

Many of the online comments so far have focused on creating a livable city, and it is wonderful to see so many positive ideas and accurate identification of challenges. Intelligent conversation like this is rare in the Sacramento news blogs. I’ll make some comments specifically on the walkability safety aspects. I’ve written about this before, but it is worth writing about again and again, because the problems still exist.

Traffic sewers: Multiple lane and one way streets are traffic sewers. This epithet is used to describe streets designed to flush traffic in and out of employment centers (and to homes in the suburbs) twice a day. They serve no other reasonable purpose, and they make a place very much less walkable. Three (or more) lane roadways are incompatible with walkability. They encourage high speed traffic, and provide too long a crossing distance to pedestrians to be comfortable with. They don’t meet the “8-80” criteria, of being safe and comfortable for people of all ages.Solutions:

Therefore, I think that all three-lane roadways in Sacramento must be narrowed to two lanes. If a true refuge median is provided between two directions of travel, at least three feet wide, so that a person can cross each direction of traffic separately, then roadways with a total of four lanes are acceptable. If not, then only a total of two lanes. Six lane or more roadways, common in the northern and southern suburbs of the City of Sacramento, are not acceptable.
One way streets also encourage high speed travel. I think that all of our one way streets should be converted to two way streets. This can be done over time as streets are repaved, it is not as high a priority as the narrowing of streets, above.

Aggressive midtown drivers

2012/03/232016/12/13 Dan Allison2 Comments

I’ve only lived in midtown a while, but from the first it was clear to me that here was a walker and bicyclist paradise, at least in comparison to where I’d lived before, Carson City, and where I work, Citrus Heights. It still seems a bicyclist paradise to me, but I’m seeing the dark side for pedestrians. This may be a recent development, or perhaps I’ve just become more aware of the reality. Though I bike more than I walk, I’m certainly a pedestrian too, and there are a large number of pedestrians in midtown.

Many drivers in midtown are aggressive towards pedestrians. At times I think this is mostly commuters who live elsewhere and just work here, but at times I’m sure it includes the people who live here as well. Driver behavior I see on a daily basis:

Speeding: drivers exceed the posted speed limit, especially on the one-way streets
Failure to yield: drivers do not yield to pedestrians in marked and unmarked crosswalks; this is a violation of the law
Failure to stop: drivers do not stop in additional lanes when one driver has stopped; this is a violation of the law
Aggressiveness: drivers do not yield to pedestrians waiting to use marked and unmarked crosswalks; this is a violation of human decency
