Why Jefferson Park residents should allow more housing

August 20, 2018 / / 0 Comments

Short answer: To provide more shoppers for the local businesses. Read on for the longer answer. 

Over on Chicago Cityscape I added a new feature called “market analysis” which measures the number of people who live within specific walking areas (measured by time) and driving areas (measured by distance). 

I am in favor of removing apartment & condo bans in Chicago, especially in areas where they were previously allowed and near train stations.

Jefferson Park is centered around two co-located train stations, serviced by CTA and Metra respectively. There have been multiple proposals for multi-family housing near the stations (collectively called the Jefferson Park Transit Center) and some have been approved. 

Always, however, there are residents who resist these proposals and the number of originally proposed apartments or condos gets reduced in the final version (classic NIMBYism). 

There’re four reasons – at least – why more housing should be allowed near the Jefferson Park Transit Center:

  • Locally owned businesses require a significant amount of shoppers who live nearby and walk up traffic
  • More people should have the opportunity to live near low-cost transportation
  • It will include more affordable housing, through Chicago’s inclusionary zoning rules (the Affordable Requirements Ordinance, ARO)
  • There will be less driving, and therefore lower household transportation costs and less neighborhood pollution

To support the first reason, I used the “market analysis” tool to see just how many people live in a walkable area centered around Veterans Square, a mixed-use office and retail development adjacent to the train stations. 

Only 9,368 people live within a 10 minute walk to Veterans Square (get the Address Snapshot). 

Comparatively, 19,707 people live within a 10 minute walk to The Crotch, or the center of Wicker Park, at the intersection of Milwaukee/North/Damen (get the Address Snapshot). The Blue Line station is about 75 feet south of the center point.

I would grant the low Veterans Square number a small discount based on the proximity to the Kennedy Expressway, which severely truncates walking areas up and down the northwest side. Still, even with that discount, ending up with less than half the amount as the one in Wicker Park, is disturbing. Wicker Park is hardly characterized by high-density housing. In fact, all of the new high-rises are just outside the 10 minute walk shed!

Which Chicago buildings have the worst energy efficiency?

April 21, 2018 / / 0 Comments

About five years ago (I’m too lazy to look it up right now), the City of Chicago adopted an energy benchmarking law. This means that owners of buildings of a certain size would soon be required to report how much energy (electricity, natural gas, district steam, chilled water, and other fuels) their buildings use. Every few years they have to audit their reports.

The city has posted three years of energy reports for the “covered” buildings (the ones of a certain size) on its data portal. I copied the Chicago Energy Benchmarking dataset into the Chicago Cityscape database (for future features) and then loaded it into QGIS so I could analyze the data and find the least efficient buildings in Chicago.

The dataset has all three years so I started the analysis by filtering only for the latest year, 2016. I first visualized the data using the “ghg_intensity_kg_co2e_sq_ft” column, which is “greenhouse gas intensity, measured in kilograms of carbon dioxide equivalent per square foot”. In other words, how much carbon does the building cause to be emitted based on its energy usage and normalized by its size.

In QGIS, to symbolize this kind of quantitative data, it helps to show them in groups. Here are “small fry” emitters, medium emitters, and bad emitters. I used the “Graduated” option in the Symbology setting and chose the Natural Breaks (Jenks) mode of dividing the greenhouse gas intensity values into four groups.

There are four groups, divided using the Natural Breaks (Jenks) method. There’s only one building in the “worst” energy users group, which is Salem Baptist Church, marked by a large red dot. The darker red the dot, the more energy per square foot that building consumes.

Among the four groups, only one building in Chicago that reported in 2016 was in the “worst emitters” group: Salem Baptist Church of Chicago at 10909 S Cottage Grove Avenue in Pullman.

The Salem Baptist Church building was built in 1960, has a gross floor area of 91,800 square feet, and an Energy Star rating of 1 because it emits 304.6 kilograms of carbon dioxide equivalent per square foot (kgco2esf). (The Energy Star rating scale is from 1 to 100.)

The next “worse” emitter in the same “Worship Facility” category as Salem Baptist Church is several magnitudes of order lower. That’s St. Peter’s Church at 110 W Madison Street in the Loop, built in 1900, which emits 11.7 kilograms of carbon dioxide equivalent per square foot (but which also has an Energy Star rating of 1).

The vast difference is concerning: Did the church report its energy usage correctly, or are they not maintaining their HVAC equipment or the building and it’s leaking so much air?

A different building was in the “worst” emitter category in 2015 but improved something about the building by 2016 to use a lot less energy. Looking deeper at the data for Piper’s Alley, however, something else happened.

In 2015, Piper’s Alley reported a single building with 137,176 gross square feet of floor area. The building’s owner also reported 5,869,902 kBTUs of electricity usage and 1,099,712,681 kBTUs of natural gas usage. Since these are reported in kilo-BTUs that means that you multiply each number by 1,000. Piper’s Alley reported using 1 trillion BTUs of natural gas. Which seems like an insane amount of energy usage, but could be totally reasonable – I’m not familiar with data on how much energy a “typical” large building uses.

Piper’s Alley in Old Town is the building that reported two different floor areas and vastly different energy usage in 2015 and 2016. The building’s owner didn’t report data for 2014 (although it may not have been required to).

There’s another problem with the reporting for Piper’s Alley, however: For 2016, it reported a gross floor area of 217,250 square feet, which is 36 percent larger than the area it reported in 2015. The building reported using significantly more electricity (58 percent more) and significantly less natural gas (137 percent less), for a vastly lowered kgco2esf value.

I think the energy benchmarking data set needs more eyes on it. Discuss in the comments below, or reply to my Twitter thread.

Upzone the 606

Map of the single family-only zoning around the Bloomingdale Trail

The area in green only allows single-family houses to be built.

Something’s gotta give.

This is all of the land area within two blocks of the Bloomingdale Trail that allows only single-family housing to be built (view full map). This isn’t to say that multi-family housing doesn’t exist here; it definitely does, and there’s probably a handful of two-flats on a majority of the blogs.

All of the five parks of the 606 are within this two block radius, and 49.6 percent of the land allows only single-family housing to be built.

But why build a transportation corridor, a park, a new, expensive, public amenity, and not change the kind of housing – which often determines the kind of family and makeup of a household – that can afford to buy a home near here.

It’s already been shown that detached single-family housing prices have grown intensely the closer you get to the trail. That price growth has meant displacement for some, and “no chance to buy or build a house here” for many others.

There are still plenty of vacant lots within the mapped area; lots that should have a 2-4 unit building built on them, but where only a 1-unit building is allowed.

This map was made possible by the new Zoning Assessment tool on Chicago Cityscape. Read about it or use it now.

Yes, please, to Accessory Dwelling Units and adopting Vancouver’s policy

income property

There’s a couch house back there, providing an income opportunity for the owner of this single-family house. It’s hard to find photos of coach houses in Chicago because, given their position behind the house, it’s hard to see them from the street! Photo by Curtis Locke

I’m a huge opponent of how cities use zoning to keep densities very low and prevent people from moving into a neighborhood to enjoy high quality public schools and good access to transit. This is evidenced by many of my tweets about zoning analyses in Chicago over the last two weeks, and many blog posts I’ve written over the years.

I’m a proponent of Accessory Dwelling Units. In Chicago these are most commonly seen, in practice, as coach houses, which were built before most of us were born. ADUs, because they’re behind the primary building on a lot, are a nearly-hidden, low-impact way to provide affordable housing for a couple more people per lot without affecting the “character” of the neighborhood. And they generate rental income for the family that owns the primary building!

Coach houses, and ADUs, are illegal in Chicago. You’re allowed to keep the one you have, and it can be rented out to anyone else, so long as you don’t renovate it.

Bryn Davidson is an architect based in Vancouver, B.C., and his firm, Lanefab, designs ADUs in that city, a housing type that was legalized in 2009. He wrote an article in CityLab today and there are *so many quotable parts*.

In the article, Davidson offers five strategies for a city that’s developing an ADU legalization policy.

In the “Keep the approvals process simple” strategy, Davidson says that Vancouver’s policy means homeowners “don’t have to solicit feedback from neighbors”, adding, “The…is perhaps the most important. In North America we have a long history of granting neighbors truly extraordinary veto powers when it comes to adding new housing. Going forward, if we want to treat younger generations and renters more fairly, we need to stop trying to litigate housing on a lot-by-lot basis.”

This is one of the worst things about zoning today. Zoning is supposed to be the way that you tell property owners what they can expect to be able to build, and it’s a way for cities or residents to manage certain aspects about the way their area looks and who is living there.

But if everywhere in the city (cough Chicago cough) where people want to build is improperly zoned to begin with – for example, allowing only single-family houses near train stations in areas that have hundreds of apartment buildings that predate that zoning – you get a situation where so many property owners have to ask their city council member for a zoning change.

The next quotable is…the entire parking strategy. But here’s some choice parts:

  • “We argued at length about parking in Vancouver, but in the end, opted to require only one onsite parking space…”
  • “Some neighbors will get irate about the new competition for street parking, but here’s the counterpoint: If a neighbor is complaining about street parking, it’s because they’re using their garage…for something else”
  • “Either way, a lot of single-family-home residents are parking on city property for free while extracting extra value out of their private land.”

Chicago is experiencing gentrification, with rising property values and taxes in neighborhoods filled with households that can least afford it. Many of these households live in a single-family house – what do you think about giving them the opportunity to renovate and rent out an existing coach house in North Lawndale, or build a new coach house in Humboldt Park?

We can actually measure the “character of the neighborhood”

June 18, 2017 / / 0 Comments

The vacant lots on the 2300 block of W Erie Street are owned by the City of Chicago.

At many public meetings about development proposals, people oppose new housing on their block because it “doesn’t fit in with the character of the neighborhood”.

This is often a code or mask that the person is trying to prevent anything from changing on their block (a.k.a. NIMBY), and sometimes trying to prevent a certain kind of person (poor, Black, disabled, veteran, you name it) from living near them.

Chicago is selling six vacant lots (marked as one parcel & PIN) to a developer for $6 who will buy six single-family houses that will cost about $247,000. Only a person or family who earns up to 120 percent of the area median income could apply to purchase the house; they have to live in it for 15 years.

The other dominant building type on the block are these one-story single-family houses.

I personally think that two-flats should be built here, because land is expensive and scarce, and there should be more affordable housing everywhere in Chicago.

Are there objective ways to measure the character of a block or neighborhood? Sometimes when people say character they mean that the proposed buildings are too tall, relative to existing buildings. Other times they mean that theirs is a single-family neighborhood and thus anything with more than one unit per lot is “out of character”.

One of the common building types on the block are these masonry single-family houses.

I can measure that. I’ve started developing a query against the Cook County property tax database that Chicago Cityscape has which will count the different property types on any given block.

One of the six lots is 2327 W Erie St (it’s currently classified as “UnClassified”). Here’s a breakdown of the other property types on the block:

  • Residential garage (1 of these)
  • Apartment building with 2 to 6 units, any age (5 of these)
  • One Story Residence, any age, 1,000 to 1,800 square feet (10 of these)
  • Two or more story residence, up to 62 years of age, 2,001 to 3,800 square feet (8 of these)

The dominant building type is a single-family house smaller than 1,800 square feet. The proposed houses will have 2,500 square feet and two stories, which is similar to the characteristics of the second most present building type on the 2300 block of W Erie St.

I’ll be rolling out this feature within a couple of weeks on Chicago Cityscape after some more testing. (Right now it can only grab the properties in the red boundary on the above map, and not the corner properties that have addresses on the intersecting streets, because the query uses string matching to find addresses on “W ERIE ST” with building numbers between and including 2300 and 2399.)

Which block do you want me to test?

They didn’t pave paradise, but they still put up a parking lot

The building

Two light industrial building were purchased and demolished in order to build more car parking for WMS Gaming in the Avondale community area. Congratulations on the success of WMS Gaming that they are hiring more people, but this kind of development is transit “dis-oriented”.

Nearly an entire block face of California from Melrose to Roscoe will have a surface parking lot. Across the street to the west, and across the street to the south is entirely residential.

The Chicago Department of Planning and Development staff wrote in their report to the Chicago Plan Commission that the project “Promotes economically beneficial development patterns that are compatible with the character of existing neighborhoods (per 17-8-0103) as evidenced by the compatibility of off-street parking within the broader industrial park character of the surrounding area.”

The Plan Commission had to approve the demolition of these buildings and the additional parking lots because they were not allowed in Industrial Planned Development 1151.

The change was neither an economically productive use of the land, nor is it “compatible with the character” of half of the surrounding area.

This might be economically productive for WMS Gaming, so more of its workers can drive. But there are more ways to get around than driving.

WMS Gaming is near the 52-California bus route. It’s also two blocks from the 77-Belmont bus route and 152-Addison bus route. WMS Gaming can operate a shuttle to CTA or Metra stations.

Turning what was – and still could be – productive space has now been turned into entirely productive

What should this area in Chicago be called?

February 15, 2016 / / 1 Comment

The area is generally bounded by Harrison Street or Congress Parkway, Dan Ryan Expressway or Desplaines Street, Roosevelt Road, and the Chicago River.

The area is generally bounded by Harrison Street or Congress Parkway, Dan Ryan Expressway or Desplaines Street, Roosevelt Road, and the Chicago River.

Currently it’s called the South Loop, which is a neighborhood name. It’s in the “Near West Side” community area. See how the City of Chicago mapped the “South Loop” in the past when it used to keep track of neighborhood boundaries.

I think it should have a new name. It should not be called the South Loop because the commonly identified center of the South Loop is probably somewhere between Roosevelt and Harrison, and Michigan Avenue and State Street, very far from this area. It just might be the Roosevelt CTA station, which has over 12,000 boardings a day.

Saying that you’re going to some business that’s west of the river and saying that the business is in the South Loop would confuse a lot of people as to what its nearby.

It’s more of an industrial and commercial area that gained a lot of new big box (faceless) retail in the 2000s, so very few people live there. There are several stores that exist that came decades before the big box outlets; for fabric, clothing, shoes, and suits. It’s probably these independent store owners that can point to an older neighborhood name as they were the center of consumer commerce in this area.

It’s easy to give it a new name. Most of the housing is north of Harrison Street. It’s difficult to figure out how many people live here because the block groups for this area include more than the area in question.

It’s easy to argue that because of the land uses, it really has no current identifiable “place” or pattern that attracts people. I’d like to know more about its history and, South Loop being a modern name, its previous names.

Which places in Chicago get the most building permits?

December 13, 2015 / / 0 Comments

View from the CTA green roof

The Merchandise Mart in the Near North Side community area ranks second place in locations receiving the most building permits.

Ed. note: I changed the title of this blog post because one interpretation of the original, “Where are the most building permits issued in Chicago?”, has the answer “City Hall”, the location of the issuer. My bad. 

Without regard to type or construction cost, the most building permits in the City of Chicago are issued at 11601 W Touhy Ave.

Where is that? It depends on which geocoder you use.

Two buildings at 11601 W Touhy Ave from Google Street View. The City of Chicago has issued thousands of building permits to this address, but the work is actually distributed across the O'Hare airport grounds. Google Maps and the Cook County parcel map places these buildings in Des Plaines.

Google Maps puts it on this building that’s on a street called “Upper Express Drive” and in the city of Des Plaines, Illinois. But the City of Chicago wouldn’t issue building permits in another city.

Our own geocoder converts the geographic coordinates given in the city’s building permits database for these permits to the address “399 E Touhy Ave, Des Plaines, IL”. The Cook County parcel for the same location has the address “385 E Touhy Ave, Des Plaines, IL”.

Now where is this building?

It’s at O’Hare airport, and it’s one of a handful of addresses* the city’s buildings departments uses to denote permits issued to work at O’Hare. Since 2006 to Saturday, December 12, 2015, there’ve been 2,403 building permits issued here. The permits’ work descriptions indicate that a lot of the work occurs elsewhere on the airport grounds.

13 buildings have had more than 400 permits issued since 2006 to yesterday.

A pattern emerges: 10 of these 13 buildings are in the Central Business District and the other three are O’Hare airport, McCormick Place (2301 S Lake Shore Drive), and Midway airport (5700 S Cicero Ave).

The first location that’s outside the Central Business District and not one of the city’s airport or its convention center is at 1060 W Addison St – better known as Wrigley Field – in the Lake View community area with 321 building permits issued. It ranks #30. If you keep running down the list, the next most frequently issued location is 7601 S Cicero Ave – that’s the Ford City Mall and I think the city’s only sprawl-style indoor mall. It ranks #39 because it pulls monthly electric maintenance permits.

The Merchandise Mart’s position at #2 is notable because the majority of its permits are for small amounts of work: there is a lot of electrical rewiring done because of the frequent shows and exhibitions in the interior design materials “mall”.

The Mart sees other activity, though, including multi-million renovations for technology companies like Motorola Mobility and Braintree. The Mart also received a permit this year for a new $3 million staircase construction, part of its building-wide renovation project.

Rendering of new main (south) lobby staircase at the Merchandise Mart

This rendering shows a new grand staircase that will be built in the Merchandise Mart’s south lobby jutting from the side of the lobby that’s between the doors on the Chicago River side, and the reception desk and central elevator bank. A building permit issued this fall puts the construction cost at $3 million.

If you want to know more about building trends in Chicago, send me a message through the Chicago Cityscape website and I can put together a custom report for you.

* Other addresses I’ve noticed are:

  • 10000 N Bessie Coleman Dr
  • 10000 W Ohare St
  • 11600 W Touhy Ave
  • 11555 W Touhy Ave

Of these only the two Touhy Ave addresses are logical: O’Hare Street isn’t a real road, and 10000 N Bessie Coleman Dr is much further north than the northernmost point in Chicago.

How to use Chicago Cityscape’s upgraded names search tool

December 7, 2015 / / 0 Comments

Search for names of people who do business in Chicago.

I created a combined dataset of over 2 million names, including contractors, architects, business names, and business owners and their shareholders, from Chicago’s open data portal, and property owners/managers from the property tax database. It’s one of three new features published in the last couple of weeks.

Type a person or company name in the search bar and press “search”. In less than 1 second you’ll get results and a hint as to what kind of records we have.

What should you search?

Take any news article about a Chicago kinda situation, like this recent Chicago Sun-Times article about the city using $8 million in taxpayer-provided TIF district money to move the Harriet Rees house one block. The move made way for a taxpayer-funded property acquisition on which the DePaul/McCormick Place stadium will be built.

The CST is making the point that something about the house’s sale and movement is sketchy (although I don’t know if they showed that anything illegal happened).

There’re a lot of names in the article, but here are some of the ones we can find info about in Chicago Cityscape.

Salvatore Martorina – an architect & building permit expeditor, although this name is connected to a lot of other names on the business licenses section of Cityscape

Oscar Tatosian – rug company owner, who owned the vacant lot to which the Rees house was moved

Bulley & Andrews – construction company which moved the house

There were no records for the one attorney and two law firms mentioned.

A century old former radium extraction site in Bronzeville gets building permit

November 9, 2015 / / 0 Comments

Map of the Carnotite Reduction Company site near Bronzeville

The Carnotite Reduction Company site near Bronzeville. Map: OpenStreetMap

A recently-issued building permit on 26th Street just east of King Drive in the Prairie Shores neighborhood of the Near South Side community area (near Bronzeville) caught my eye.

Installation of temporary wood poles and aerial cable, to powering air monitors, for the Carnotite Reduction Company site project

Carnotite wasn’t a word I’ve heard before, and “Carnotite Reduction Company” isn’t a business I’ve heard of before, either.

I searched Bing and found that 4 of the 5 results were about cleaning up a contaminated site, and one of the results was a letter in PDF form hosted on the Centers for Disease Control and Prevention website prepared by a scientist at the Illinois Department of Public Health.

The letter is 11 pages long and tells the story about Carnotite Reduction Company, which had a factory in 1915 on what’s now known as the Michael Reese Hospital site, the buildings of which have all been demolished.

The Carnotite Co. mainly produced radium, along with some uranium and vanadium as byproducts.

The Carnotite Co. owned and operated mines in Colorado and Utah. In 1919, it was one of four companies that mined 95% of the carnotite ore produced in Colorado. The U.S. dominated the world radium market until 1922, when Belgium began using pitchblende ore from the Belgian Congo. The pitchblende was 40 to 100 times more pure than carnotite, and by 1923, Belgian competition ended carnotite ore processing in the U.S.

This article from the “Chicago Chemical Bulletin” publication in 1917 linked on the United States Environmental Protection Agency’s website about the cleanup project describes carnotite ore and mining process. They’ve cataloged this site as EPA ID# ILN000510371.

Chicago Chemical Bulletin: 1917 article about the Carnotite Reduction Company

The letter describes where radioactive, contaminated soil was found during boring tests made within the last three years, and how it potentially got there. The factory was extracting radium there, for an exploding cancer research trend, until 1920.

The company, the EPA believes, may have disposed its waste into public infrastructure.

The US Environmental Protection Agency (USEPA) suspects that the Carnotite Co. may have sent this liquid waste into the sewer, floor drains, or reintroduced it into the process for further refining. Because streets in the area, including Inglehart Court, were abandoned during the redevelopment in the 1950s and 1960s, sewers running along those abandoned streets likely also were abandoned. Other options for liquid waste disposal commonly used at the time included streams or ditches (with Lake Michigan in the vicinity), waste ponds, dug wells, and dumping wastes on porous ground (such as the sand on-site).

When the City of Chicago was preparing the site in 2009 for a potential Olympic Village for its 2016 Olympic Games bid – buying the property for an insane amount of cash and then razing it all, while eventually losing the bid to Rio de Janeiro – conducted “Phase I and Phase II environmental investigations” but didn’t survey for radiological contamination and didn’t uncover an important survey from 30 years prior.

The Illinois Department of Public Health found radioactive contamination after a “radiological surface survey” of the Michael Reese hospital site in 1979.

The IDPH Division of Radiological Health concluded that the contamination did not pose an immediate health threat, but should be taken into account before any future construction. In 1979, IDPH did not notify USEPA about the contamination they found.

The Illinois Emergency Management Agency surveyed the site in August 2009 and found the contamination, alerted the EPA, and met with the City of Chicago to discuss remediation.

The letter details further testing by AECOM, a global transportation, infrastructure, and engineering company, the levels of contamination, and risk assessment. It appears that the contamination won’t be a danger to most people.

The Illinois Department of Public Health concludes that exposure at the Carnotite Co. site to the area with the greatest surface radium and uranium concentration for 20 minutes per day, five days per week, 250 days per week, for 50 years is not expected to harm people’s health. IDPH considers this to be a maximum likely exposure scenario, given current conditions at the site.

It notes that a change in land use – the site is currently occupied by vacant hardscape, tennis courts, a park, sidewalks, and grassy areas – “could increase exposure duration”, especially if housing was built here.

The City of Chicago applied for a license in 2013 to temporarily store radioactive material on site before shipping it to a disposal facility. The EPA last updated its website in April 2014 to say that it was considering this application.
