How much of the land within walking distance of a CTA station is zoned to allow multi-family housing?

November 17, 2017 / / 0 Comments

I recently created the Zoning Assessment tool on Chicago Cityscape, which shows a map of aggregated zoning districts in a given community area, ward, or near a CTA or Metra station. Per Paul Angelone’s suggestion, you can now show the walk shed – the area within walking distance to the station, following the streets.

The maps in this post show where one can build apartments (including a simple and common two-flat) within a 15 minute walk to the Logan Square Blue Line station, which has 24-hour service. Try it yourself.

Thirty-one percent of the walk shed allows multi-family housing.

In a second version of the same map, I’ve marked in red the gaps in the zoning map. These are areas that are zoned to allow only single-family housing. That doesn’t make sense: The land near rapid transit stations should be much denser than the land away from the stations.

Sixty-four percent of the walk shed allows only single-family housing. The remaining five percent are planned developments (at least the Mega Mall is going to have a couple hundred dwelling units), manufacturing, and parks.

And if most of the block is already zoned to allow multi-family housing, why are these parcels skipped?

This is the same map as the one above, but with areas that allow only single-family housing marked in red (however, I skipped some areas to save myself time).

How it works
The walk shed boundaries are generated by Mapzen’s isochrone service. The Zoning Assessment map asks Mapzen for the polygon of a specified walk shed (walk or bike, 10 or 15 minutes), receives the polygon and sends that polygon to a custom API on the Cityscape server, which compares that to the server’s copy of Chicago’s latest zoning map. The comparison is then returned to the browser and replaces the default Zoning Assessment map.

People want more walkability and property developers can make it happen

This is my favorite part of Sam Schwartz’s book “Street Smart” so far. You’ll find it on page 117 following a discussion of Walk Score, a tool used mostly by realtors that measures “walkability” of any place in American cities based on the location and diversity of services, shops, and amenities nearby.

Every way you slice the data confirms that what all the polls say is true: people want more walkability.

Why, then, is there so little of it?

Why is there such a mismatch between the supply of, and the demand for, walkable neighborhoods?

Is it because, as one observer wrote, “Americans would like to live in places that don’t really exist”?

Do you live in a walkable place? Answer, and then check your Walk Score. I’m curious to know if they match.

Schwartz answers these questions with “not really”.

They want to live in places that do exist, but there are far too few of them.

Schwartz mentions that the housing prices in the most walkable cities – San Francisco, Washington, D.C., and New York City – are so expensive, but being walkable is what makes them the “coolest” cities.

Higher Walk Scores positively correlate with higher housing prices, “which is a problem”, Schwartz says.

[It’s] also an opportunity. By definition, only a few neighborhoods can be the coolest places to live. But that doesn’t mean we can’t make everywhere cooler.

Many pages later Schwartz describes how one city attempted to get property developers to make their proposed buildings or complexes more receptive to walking and biking (active transportation).

Columbus, Ohio, needed to lose some body weight. The city’s sprawling nature contributed to 59 percent of adults being obese or overweight, and 38 percent of children in the third grade (here’s the citation).

The Columbus Healthy Places program was formed in 2006 and implemented by the transportation and public health departments. Here’s one of the strategies they undertook to affect the built environment.

[The transportation and public health officials] persuaded the [buildings] department to grant them an opportunity to comment on all requests from developers to rezone a particular bit of land.

With that opportunity, Schwartz explained on page 133, they proposed that developments with shopping centers, bus stops, schools, park, libraries, drugstores, or grocery stores, within half a mile of residences, “include a suite of active transportation elements” like bike parking, connections to bike lanes and trails, and wider sidewalks.

It worked, he said. Before the program only seven percent of projects requesting a zoning change included active transportation elements, but after it was reviewed by the Columbus Healthy Places managers it “jumped” to 64 percent.

Welcome back, Bloomingdale Trail

June 12, 2015 / / 2 Comments

Back to transportation service, that is.

Before it was the Bloomingdale Trail – associated parks comprising The 606 – it was the Bloomingdale Line, an elevated railroad route along Bloomingdale Avenue to serve industrial customers in Humboldt Park, Logan Square, Bucktown, and Wicker Park.

It was abandoned in the early 2000s. I don’t know when the last customer received a delivery via the line. It reopened to use for transportation on June 6, 2015, or 6/06. Now that same embankment transports pedestrians and bicyclists, in addition to providing new recreational and public space.

I’ve ridden and walked on it four times now since the opening and there are people all over the place on it. I tweeted as much last night.

On Monday, two days after opening, I filmed this 14-minute video of the entire west-to-east length and condensed it to 4 minutes.

The solution to its crowding problem (I guess one of those “good problems to have”) is more. More car-free spaces. More low-stress transportation spaces. Space for walking, and space for cycling. Which we currently don’t have on the ground.

Study recommends designing bike paths for bikes, not for sharing

running and bicycling on the lakefront trail

Some parts of the Chicago Lakefront Trail have a 2-foot wide side path designed for pedestrians but the study reviewed very cases where bicyclists crashed with pedestrians. It’s unknown if this side path results in fewer crashes than the parts of the Lakefront Trail without it. Photo: Eric Allix Rogers

The Active Transportation Alliance posted a link on Facebook to a new study [PDF] in the Open BMJ from December 2014, a free peer-reviewed “version” of the British Medical Journal, and said it “conclusively shows separated space reduces crashes and the severity of injuries when crashes occur”.

The posting was in the context that bicyclists and pedestrians using the Lakefront Trail should have separate paths. I agree, but there’s a problem in how they stated the study’s support for separation.

I wouldn’t say that the study “conclusively” shows that bicyclists would fare better on paths without pedestrians. The study reviewed fewer than 700 crashes in two Canadian cities. Only 11% of those crashes occurred on multi-use trails and only 5.9% of the crashes were with a pedestrian or animal (the two were grouped) – this sample size is too low from which to draw that kind of conclusion.

The study didn’t report the association (correlation) between crash severity and pedestrians. The authors didn’t even recommend that bicyclists and pedestrians have separate paths, but instead wrote “These results suggest an urgent need to provide bike facilities…that are designed [emphasis added] specifically for bicycling rather than for sharing with pedestrians”.

While I don’t discount the possibility that separating bicyclists and pedestrians in off-street corridors will reduce the number of crashes and injuries when those two user groups collide, it’s imprudent to call this study “conclusive” when linking it to the measure of crashes between bicyclists and pedestrians.

The study’s primary conclusion was that bicyclists crash more often when there are high slopes, fast moving cars, or no bike lanes and the authors recommended that bike infrastructure be built for bicycling. That’s a solid recommendation and I recommended that you sign Active Trans’s petition advocating for separate facilities in the North Lake Shore Drive reconstruction project.

What’s up from Europe: London pedestrian spaces

April 12, 2014 / / 0 Comments

I found walking around in London a tad stressful, as crossing the street can only be safely done at signalized intersections, or at zebra crossings with the flashing yellow globe. Crossing the street safely is then compounded by the left-driving traffic. The “< Look Left” and “Look Right >” messages aren’t printed at all intersections and there’s a delay at signalized intersections because you can’t cross every other phase: you have to wait until the all-walk phase (when signals stop traffic in all directions).

However, London still has a lot of great pedestrian spaces and alleys (with bars and pubs) scattered around the town. It doesn’t have as much car-free space as city centers in the Netherlands and Germany. These three photos show three spaces on my many long walks around the town during my three-day trip there*.

Hay’s Galleria, seen on my Thames Path walk along the south bank. It was redeveloped in 1987 to the design and condition you see here. Like many pedestrian spaces I passed by and walked through this one is privately owned (and monitored). 

This pedestrian space off of St. John’s Road near the Clapham Junction station (with National Rail and London Overground services) was created simply by blocking car traffic from entering or exiting St. John’s Road. It has distinct pavers that match the high street – it’s not exactly a shared space as buses have priority but there is limited traffic otherwise because only delivery and construction workers can access the road. 

Old Spitalfields Market has been redeveloped – it maintains the old buildings and look on the edges with shops and restaurants but has a modern glass and steel roof with modern construction on the interior for more shops and restaurants. Even if you aren’t shopping here passersby can use it as a shortcut through the block.

* Calling it three days is a stretch because I was tired and slept a lot, missing precious walking and exploring time. I still managed to spend over an hour walking around Queen Elizabeth Olympic Park and go shopping at Westfield Stratford City for about two hours.
